4.1 Therapeutic indications

Soliris is indicated in adults and children for the treatment of:

- Paroxysmal nocturnal haemoglobinuria (PNH).

Evidence of clinical benefit is demonstrated in patients with haemolysis with clinical symptom(s)indicative of high disease activity, regardless of transfusion history (see section 5.1).

- Atypical haemolytic uremic syndrome (aHUS) (see section 5.1).

- Refractory generalized myasthenia gravis (gMG) in patients aged 6 years and above who are anti-acetylcholine receptor (AChR) antibody-positive (see section 5.1).

Soliris is indicated in adults for the treatment of:

- Neuromyelitis optica spectrum disorder (NMOSD) in patients who are anti-aquaporin-4 (AQP4)antibody-positive with a relapsing course of the disease (see section 5.1).

4.2 Posology and method of administration

Soliris must be administered by a healthcare professional and under the supervision of a physicianexperienced in the management of patients with haematological, renal, neuromuscular or neuro-inflammatory disorders.

Home infusion may be considered for patients who have tolerated infusions well in the clinic. Thedecision of a patient to receive home infusions should be made after evaluation and recommendation fromthe treating physician. Home infusions should be performed by a qualified healthcare professional.

Posology

Paroxysmal Nocturnal Haemoglobinuria (PNH) in adults

The PNH dosing regimen for adult patients (≥18 years of age) consists of a 4-week initial phase followedby a maintenance phase:

* Initial phase: 600 mg of Soliris administered via a 25 - 45 minute (35 minutes ± 10 minutes)intravenous infusion every week for the first 4 weeks.

* Maintenance phase: 900 mg of Soliris administered via a 25 - 45 minute (35 minutes ± 10 minutes)intravenous infusion for the fifth week, followed by 900 mg of Soliris administered via a 25 -45 minute (35 minutes ± 10 minutes) intravenous infusion every 14 ± 2 days (see section 5.1).

atypical Haemolytic Uremic Syndrome (aHUS), refractory generalized Myasthenia Gravis (gMG) and

Neuromyelitis Optica Spectrum Disorder (NMOSD) in adults

The aHUS, refractory gMG and NMOSD dosing regimen for adult patients (≥18 years of age) consists ofa 4 week initial phase followed by a maintenance phase:

* Initial phase: 900 mg of Soliris administered via a 25 - 45 minute (35 minutes ± 10 minutes)intravenous infusion every week for the first 4 weeks.

* Maintenance phase: 1,200 mg of Soliris administered via a 25 - 45 minute (35 minutes ± 10minutes) intravenous infusion for the fifth week, followed by 1,200 mg of Soliris administered via a25 - 45 minute (35 minutes ± 10 minutes) intravenous infusion every 14 ± 2 days (see section 5.1).

Refractory gMG

Available data suggest that clinical response is usually achieved by 12 weeks of Soliris treatment.

Discontinuation of the therapy should be considered in a patient who shows no evidence of therapeuticbenefit by 12 weeks.

Paediatric patients in PNH, aHUS, or refractory gMG

Paediatric PNH, aHUS, or refractory gMG patients with body weight ≥ 40 kg are treated with the adultdosing recommendations.

In paediatric PNH, aHUS, and refractory gMG patients with body weight below 40 kg, the Soliris dosingregimen consists of:

Patient Body Initial Phase Maintenance Phase

Weight30 to <40 kg 600 mg weekly for the first 2 900 mg at week 3; then 900 mg every 2 weeksweeks20 to <30 kg 600 mg weekly for the first 2 600 mg at week 3; then 600 mg every 2 weeksweeks10 to <20 kg 600 mg single dose at week 1 300 mg at week 2; then 300 mg every 2 weeks5 to <10 kg 300 mg single dose at week 1 300 mg at week 2; then 300 mg every 3 weeks

Soliris has not been studied in patients with PNH or refractory gMG who weigh less than 40kg. Theposology of Soliris to be used in paediatric patients with PNH or refractory gMG patients weighing lessthan 40 kg is identical to the weight-based dose recommendation provided for paediatric patients withaHUS. Based on the pharmacokinetic (PK)/pharmacodynamic (PD) data available in patients with aHUSand PNH treated with Soliris, this body-weight based dose regimen for paediatric patients is expected toresult in an efficacy and safety profile similar to that in adults. For patients with refractory gMG weighingless than 40 kg this body-weight based dose regimen is also expected to result in an efficacy and safetyprofile similar to that in adults.

Supplemental dosing of Soliris is required in the setting of concomitant plasmapheresis (PP), plasmaexchange (PE), or fresh frozen plasma infusion (PI) as described below:

Abbreviation: IVIg = intravenous immunoglobulin

Treatment monitoringaHUS patients should be monitored for signs and symptoms of thrombotic microangiopathy (TMA) (seesection 4.4 aHUS laboratory monitoring).

Soliris treatment is recommended to continue for the patient’s lifetime, unless the discontinuation of

Soliris is clinically indicated (see section 4.4).

Elderly

Soliris may be administered to patients aged 65 years and over. There is no evidence to suggest that anyspecial precautions are needed when older people are treated - although experience with Soliris in thispatient population is still limited.

Renal impairment

No dose adjustment is required for patients with renal impairment (see section 5.1).

Hepatic impairment

The safety and efficacy of Soliris have not been studied in patients with hepatic impairment.

Paediatric population

The safety and efficacy of Soliris in children with refractory gMG aged less than 6 years old have not beenestablished.

The safety and efficacy of Soliris in children with NMOSD aged less than 18 years old have not beenestablished.

Method of administration

Do not administer as an intravenous push or bolus injection. Soliris should only be administered viaintravenous infusion as described below.

For instructions on dilution of the medicinal product before administration, see section 6.6.

The diluted solution of Soliris should be administered by intravenous infusion over 25 - 45 minutes (35minutes ± 10 minutes) in adults and 1-4 hours in paediatric patients under 18 years of age via gravity feed,a syringe-type pump, or an infusion pump. It is not necessary to protect the diluted solution of Soliris fromlight during administration to the patient.

Patients should be monitored for one hour following infusion. If an adverse event occurs during theadministration of Soliris, the infusion may be slowed or stopped at the discretion of the physician. If theinfusion is slowed, the total infusion time may not exceed two hours in adults and four hours in paediatricpatients under 18 years of age.

There is limited safety data supporting home-based infusions, additional precautions in the home settingsuch as availability of emergency treatment of infusion reactions or anaphylaxis are recommended.

Infusion reactions are described in Sections 4.4 and 4.8 on the SmPC.

4.3 Contraindications

Hypersensitivity to eculizumab, murine proteins or to any of the excipients listed in section 6.1.

Soliris therapy must not be initiated in patients (see section 4.4):

- with unresolved Neisseria meningitidis infection

- who are not currently vaccinated against Neisseria meningitidis unless they receive prophylactictreatment with appropriate antibiotics until 2 weeks after vaccination.

4.4 Special warnings and precautions for use

Traceability

In order to improve the traceability of biological medicinal products, the name and the batch number of theadministered product should be clearly recorded.

Soliris is not expected to affect the aplastic component of anaemia in patients with PNH.

Meningococcal Infection

Due to its mechanism of action, the use of Soliris increases the patient’s susceptibility to meningococcalinfection (Neisseria meningitidis). Meningococcal disease due to any serogroup may occur. To reduce therisk of infection, all patients must be vaccinated at least 2 weeks prior to receiving Soliris unless the riskof delaying Soliris therapy outweighs the risks of developing a meningococcal infection. Patients whoinitiate Soliris treatment less than 2 weeks after receiving a tetravalent meningococcal vaccine mustreceive treatment with appropriate prophylactic antibiotics until 2 weeks after vaccination. Vaccinesagainst all available serogroups including A, C, Y, W 135 and B, are recommended in preventing thecommonly pathogenic meningococcal serogroups. Patients must be vaccinated and revaccinated accordingto current national guidelines for vaccination use.

Vaccination may further activate complement. As a result, patients with complement-mediated diseases,including PNH, aHUS, refractory gMG and NMOSD, may experience increased signs and symptoms oftheir underlying disease, such as haemolysis (PNH), TMA (aHUS), MG exacerbation (refractory gMG) orrelapse (NMOSD). Therefore, patients should be closely monitored for disease symptoms afterrecommended vaccination.

Vaccination may not be sufficient to prevent meningococcal infection. Consideration should be given toofficial guidance on the appropriate use of antibacterial agents. Cases of serious or fatal meningococcalinfections have been reported in Soliris-treated patients. Sepsis is a common presentation ofmeningococcal infections in patients treated with Soliris (see section 4.8). All patients should bemonitored for early signs of meningococcal infection, evaluated immediately if infection is suspected, andtreated with appropriate antibiotics if necessary. Patients should be informed of these signs and symptomsand steps taken to seek medical care immediately. Physicians must discuss the benefits and risks of Soliristherapy with patients and provide them with a Patient guide and a patient card (see Package Leaflet for adescription).

Other Systemic Infections

Due to its mechanism of action, Soliris therapy should be administered with caution to patients with activesystemic infections. Patients may have increased susceptibility to infections, especially with Neisseria andencapsulated bacteria. Serious infections with Neisseria species (other than Neisseria meningitidis),including disseminated gonococcal infections, have been reported.

Patients should be provided with information from the Package Leaflet to increase their awareness ofpotential serious infections and the signs and symptoms of them. Physicians should advise patients aboutgonorrhoea prevention.

Infusion Reactions

Administration of Soliris may result in infusion reactions or immunogenicity that could cause allergic orhypersensitivity reactions (including anaphylaxis). In clinical trials, 1 (0.9%) refractory gMG patientexperienced an infusion reaction which required discontinuation of Soliris. No PNH, aHUS, refractorygMG or NMOSD paediatric patients experienced an infusion reaction which required discontinuation of

Soliris. Soliris administration should be interrupted in all patients experiencing severe infusion reactionsand appropriate medical therapy administered.

Immunogenicity

Infrequent antibody responses have been detected in Soliris-treated patients across all clinical studies. In

PNH placebo controlled studies low antibody responses have been reported with a frequency (3.4%)similar to that of placebo (4.8%).

In patients with aHUS treated with Soliris, antibodies to Soliris were detected in 3/100 (3%) by the ECLbridging format assay. 1/100 (1%) aHUS patients had low positive values for neutralizing antibodies.

In a refractory gMG placebo controlled study, none (0/62) of the Soliris treated patients showed antidrugantibody response during the 26 week active treatment, whereas in a refractory gMG extension study, atotal of 3/117 (2.6%) overall were positive for ADAs at any post-baseline visit. Positive ADA resultsappeared to be transient, as positive titers were not observed at subsequent visits, and there were noclinical findings in these patients suggestive of an effect of positive ADA titers.

In a NMOSD placebo controlled study, 2/95 (2.1%) of the Soliris treated patients showed antidrugantibody response post-baseline. Both patients were negative for neutralizing antibodies. Positive ADAsamples were low titer and transient. There has been no observed correlation of antibody development toclinical response or adverse events.

Immunization

Prior to initiating Soliris therapy, it is recommended that PNH, aHUS, refractory gMG and NMOSDpatients initiate immunizations according to current immunization guidelines. Additionally, all patientsmust be vaccinated against meningococcal infections at least 2 weeks prior to receiving Soliris unless therisk of delaying Soliris therapy outweighs the risks of developing a meningococcal infection. Patients whoinitiate Soliris treatment less than 2 weeks after receiving a tetravalent meningococcal vaccine mustreceive treatment with appropriate prophylactic antibiotics until 2 weeks after vaccination. Vaccinesagainst all available serogroups including A, C, Y, W 135 and B are recommended in preventing thecommonly pathogenic meningococcal serogroups. Patients must be vaccinated and revaccinated accordingto current national guidelines for vaccination use (see Meningococcal Infection).

Patients less than 18 years of age must be vaccinated against Haemophilus influenzae and pneumococcalinfections, and strictly need to adhere to the national vaccination recommendations for each age group.

Vaccination may further activate complement. As a result, patients with complement-mediated diseases,including PNH, aHUS, refractory gMG and NMOSD may experience increased signs and symptoms oftheir underlying disease, such as haemolysis (PNH), TMA (aHUS), MG exacerbation (refractory gMG) orrelapse (NMOSD). Therefore, patients should be closely monitored for disease symptoms afterrecommended vaccination.

Anticoagulant therapy

Treatment with Soliris should not alter anticoagulant management.

Immunosuppressant and anticholinesterase therapies
Refractory gMG

When immunosuppressant and anticholinesterase therapies are decreased or discontinued, patients shouldbe monitored closely for signs of disease exacerbation.

Neuromyelitis Optica Spectrum Disorder

When immunosuppressant therapy is decreased or discontinued, patients should be monitored closely forsigns and symptoms of potential NMOSD relapse.

PNH Laboratory Monitoring

PNH patients should be monitored for signs and symptoms of intravascular haemolysis, including serumlactate dehydrogenase (LDH) levels. PNH patients receiving Soliris therapy should be similarly monitoredfor intravascular haemolysis by measuring LDH levels, and may require dose adjustment within therecommended 14±2 day dosing schedule during the maintenance phase (up to every 12 days).

aHUS Laboratory MonitoringaHUS patients receiving Soliris therapy should be monitored for thrombotic microangiopathy bymeasuring platelet counts, serum LDH and serum creatinine, and may require dose adjustment within therecommended 14±2 day dosing schedule during the maintenance phase (up to every 12 days).

Treatment Discontinuation for PNH

If PNH patients discontinue treatment with Soliris they should be closely monitored for signs andsymptoms of serious intravascular haemolysis. Serious haemolysis is identified by serum LDH levelsgreater than the pre-treatment level, along with any of the following: greater than 25% absolute decreasein PNH clone size (in the absence of dilution due to transfusion) in one week or less; a haemoglobin levelof <5 g/dL or a decrease of >4 g/dL in one week or less; angina; change in mental status; a 50% increasein serum creatinine level; or thrombosis. Monitor any patient who discontinues Soliris for at least 8 weeksto detect serious haemolysis and other reactions.

If serious haemolysis occurs after Soliris discontinuation, consider the following procedures/treatments:blood transfusion (packed RBCs), or exchange transfusion if the PNH RBCs are >50% of the total RBCsby flow cytometry; anticoagulation; corticosteroids; or reinstitution of Soliris. In PNH clinical studies, 16patients discontinued the Soliris treatment regimen. Serious haemolysis was not observed.

Treatment Discontinuation for aHUS

Thrombotic microangiopathy (TMA) complications have been observed as early as 4 weeks and up to 127weeks following discontinuation of Soliris treatment in some patients. Discontinuation of treatment shouldonly be considered if medically justified.

In aHUS clinical studies, 61 patients (21 paediatric patients) discontinued Soliris treatment with a medianfollow-up period of 24 weeks. Fifteen severe thrombotic microangiopathy (TMA) complications in 12patients were observed following treatment discontinuation, and 2 severe TMA complications occurred inan additional 2 patients that received a reduced dosing regimen of Soliris outside of the approved dosingregimen (See Section 4.2). Severe TMA complications occurred in patients regardless of whether theyhad an identified genetic mutation, high risk polymorphism or auto-antibody. Additional serious medicalcomplications occurred in these patients including severe worsening of kidney function, disease-relatedhospitalization and progression to end stage renal disease requiring dialysis. Despite Soliris re-initiationfollowing discontinuation, progression to end stage renal disease occurred in one patient.

If aHUS patients discontinue treatment with Soliris, they should be monitored closely for signs andsymptoms of severe thrombotic microangiopathy complications. Monitoring may be insufficient to predictor prevent severe thrombotic microangiopathy complications in patients with aHUS after discontinuationof Soliris.

Severe thrombotic microangiopathy complications post discontinuation can be identified by (i) any two,or repeated measurement of any one, of the following: a decrease in platelet count of 25% or more ascompared to either baseline or to peak platelet count during Soliris treatment; an increase in serumcreatinine of 25% or more as compared to baseline or to nadir during Soliris treatment; or, an increase inserum LDH of 25% or more as compared to baseline or to nadir during Soliris treatment; or (ii) any one ofthe following: a change in mental status or seizures; angina or dyspnoea; or thrombosis.

If severe thrombotic microangiopathy complications occur after Soliris discontinuation, considerreinstitution of Soliris treatment, supportive care with PE/PI, or appropriate organ-specific supportivemeasures including renal support with dialysis, respiratory support with mechanical ventilation oranticoagulation.

Treatment discontinuation for refractory gMG:

Use of Soliris in refractory gMG treatment has been studied only in the setting of chronic administration.

Patients who discontinue Soliris treatment should be carefully monitored for signs and symptoms ofdisease exacerbation.

Treatment discontinuation for NMOSD:

Use of Soliris in NMOSD treatment has been studied only in the setting of chronic administration and theeffect of Soliris discontinuation has not been characterized. Patients who discontinue Soliris treatmentshould be carefully monitored for signs and symptoms of potential NMOSD relapse.

Educational materials

All physicians who intend to prescribe Soliris must ensure they are familiar with the guide for Healthcare

Professionals to prescribing. Physicians must discuss the benefits and risks of Soliris therapy with patientsand provide them with a Patient guide and a Patient card.

Patients should be instructed that if they develop fever, headache accompanied with fever and/or stiff neckor sensitivity to light, they should immediately seek medical care as these signs may be indicative ofmeningococcal infection.

Excipients with known effect
Sodium

Once diluted with sodium chloride 9 mg/mL (0.9%) solution for injection, this medicinal product contains0.88 g sodium per 240 mL at the maximal dose, equivalent to 44.0% of the WHO recommendedmaximum daily intake of 2 g sodium for an adult.

Once diluted with sodium chloride 4.5 mg/mL (0.45%) solution for injection, this medicinal productcontains 0.67 g sodium per 240 mL at the maximal dose, equivalent to 33.5% of the WHO recommendedmaximum daily intake of 2 g sodium for an adult.

Polysorbate 80

This medicinal product contains 6.6 mg of polysorbate 80 in each vial (30mL vial) which is equivalent to0.66 mg/kg or less at the maximum dose for adult patients and paediatric patients with body weight morethan 10 kg and is equivalent to 1.32 mg/kg or less at the maximum dose for paediatric patients with bodyweight 5 to <10 kg. Polysorbates may cause allergic reactions.

4.5 Interaction with other medicinal products and other forms of interaction

No interaction studies have been performed. Based on the potential inhibitory effect of eculizumab oncomplement-dependent cytotoxicity of rituximab, eculizumab may reduce the expected pharmacodynamiceffects of rituximab.

Plasma exchange (PE), plasmapheresis (PP), fresh frozen plasma infusion (PI) and intravenousimmunoglobulin (IVIg) have been shown to reduce eculizumab serum levels. A supplemental dose ofeculizumab is required in these settings. See Section 4.2 for guidance in case of concomitant PE, PP, PI, or

IVIg treatment.

Concomitant use of eculizumab with intravenous immunoglobulin (IVIg) may reduce effectiveness ofeculizumab. Closely monitor for reduced effectiveness of eculizumab.

Concomitant use of eculizumab with neonatal Fc receptor (FcRn) blockers may lower systemic exposuresand reduce effectiveness of eculizumab. Closely monitor for reduced effectiveness of eculizumab.

4.6 Fertility, pregnancy and lactation

The use of adequate contraception to prevent pregnancy and for at least 5 months after the last dose oftreatment with eculizumab should be considered for women of childbearing potential.

Pregnancy

There are no well-controlled studies in pregnant women treated with eculizumab. Data on a limitednumber of pregnancies exposed to eculizumab (less than 300 pregnancy outcomes) indicate there is noincreased risk of foetal malformation or foetal-neonatal toxicity. However, due to the lack of well-controlled studies, uncertainties remain. Therefore, an individual risk benefit analysis is recommendedbefore starting and during treatment with eculizumab in pregnant women. Should such a treatment beconsidered necessary during pregnancy, a close maternal and foetal monitoring according to localguidelines is recommended.

Animal reproduction studies have not been conducted with eculizumab (see section 5.3).

Human IgG are known to cross the human placental barrier, and thus eculizumab may potentially causeterminal complement inhibition in the foetal circulation. Therefore, Soliris should be given to a pregnantwoman only if clearly needed.

Breast-feeding

No effects on the breastfed newborn/infant are anticipated as limited data available suggest thateculizumab is not excreted in human breast milk. However, due to the limitations of the available data, thedevelopmental and health benefits of breastfeeding should be considered along with the mother’s clinicalneed for eculizumab and any potential adverse effects on the breastfed child from eculizumab or from theunderlying maternal condition.

Fertility

No specific study of eculizumab on fertility has been conducted.

4.7 Effects on ability to drive and use machines

Soliris has no or negligible influence on the ability to drive and use machines.

4.8 Undesirable effects

Summary of the safety profile

Supportive safety data were obtained from 33 clinical studies that included 1,555 patients exposed toeculizumab in complement-mediated disease populations, including PNH, aHUS, refractory gMG and

NMOSD. The most common adverse reaction was headache, (occurred mostly in the initial phase ofdosing), and the most serious adverse reaction was meningococcal infection.

Description of selected adverse reactions

In all clinical studies, the most serious adverse reaction was meningococcal sepsis which is a commonpresentation of meningococcal infections in patients treated with Soliris (see section 4.4).

Other cases of Neisseria species have been reported including sepsis with Neisseria gonorrhoeae,

Neisseria sicca/subflava, Neisseria spp unspecified.

Antibodies to Soliris were detected in 2% of patients with PNH using an ELISA assay, 3% of patientswith aHUS and 2% of patients with NMOSD using the ECL bridging format assay. In refractory gMGplacebo-controlled studies, no antidrug antibodies were observed. As with all proteins there is a potentialfor immunogenicity.

Cases of haemolysis have been reported in the setting of missed or delayed Soliris dose in PNH clinicaltrials (see also Section 4.4).

Cases of thrombotic microangiopathy complication have been reported in the setting of missed or delayed

Soliris dose in aHUS clinical trials (see also Section 4.4).

Paediatric population

In children and adolescent PNH patients (aged 11 years to less than 18 years) included in the paediatric

PNH Study M07-005, the safety profile appeared similar to that observed in adult PNH patients. The mostcommon adverse reaction reported in paediatric patients was headache.

In paediatric aHUS patients (aged 2 months to less than 18 years) included in the aHUS studies C08-002,

C08-003, C09-001r and C10-003, the safety profile appeared similar to that observed in adult aHUSpatients. The safety profiles in the different paediatric subsets of age appear similar.

In paediatric patients with refractory gMG (aged 12 to less than 18 years) included in

Study ECU-MG-303, the safety profile appeared similar to that observed in adult patients with refractorygMG.

Elderly population

No overall differences in safety were reported between elderly (≥ 65 years) and younger refractory gMGpatients (< 65 years) (see section 5.1).

Supportive safety data were obtained in 12 completed clinical studies that included 934 patients exposedto eculizumab in other disease populations other than PNH, aHUS, refractory gMG or NMOSD. Therewas an un-vaccinated patient diagnosed with idiopathic membranous glomerulonephropathy whoexperienced meningococcal meningitis. Adverse reactions reported in patients with disease other than

PNH, aHUS, refractory gMG or NMOSD were similar to those reported in patients with PNH, aHUS,refractory gMG or NMOSD (see Table 1 above). No specific adverse reactions have emerged from theseclinical studies.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allowscontinued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals areasked to report any suspected adverse reactions via the national reporting system listed in Appendix V.

4.9 Overdose

No case of overdose has been reported in any of the clinical studies.

5. PHARMACOLOGICAL PROPERTIES

5.1 Pharmacodynamic properties

Pharmacotherapeutic group: Complement Inhibitors, ATC code: L04AJ01

Soliris is a recombinant humanised monoclonal IgG2/4k antibody that binds to the human C5 complementprotein and inhibits the activation of terminal complement. The Soliris antibody contains human constantregions and murine complementarity-determining regions grafted onto the human framework light- andheavy-chain variable regions. Soliris is composed of two 448 amino acid heavy chains and two 214 aminoacid light chains and has a molecular weight of approximately 148 kDa.

Soliris is produced in a murine myeloma (NS0 cell line) expression system and purified by affinity and ionexchange chromatography. The bulk drug substance manufacturing process also includes specific viralinactivation and removal steps.

Mechanism of action

Eculizumab, the active ingredient in Soliris, is a terminal complement inhibitor that specifically binds tothe complement protein C5 with high affinity, thereby inhibiting its cleavage to C5a and C5b andpreventing the generation of the terminal complement complex C5b-9. Eculizumab preserves the earlycomponents of complement activation that are essential for opsonization of microorganisms and clearanceof immune complexes.

In PNH patients, uncontrolled terminal complement activation and the resulting complement-mediatedintravascular haemolysis are blocked with Soliris treatment.

In most PNH patients, eculizumab serum concentrations of approximately 35 microgram/mL are sufficientfor essentially complete inhibition of terminal complement-mediated intravascular haemolysis.

In PNH, chronic administration of Soliris resulted in a rapid and sustained reduction in complement-mediated haemolytic activity.

In aHUS patients, uncontrolled terminal complement activation and the resulting complement-mediatedthrombotic microangiopathy are blocked with Soliris treatment.

All patients treated with Soliris when administered as recommended demonstrated rapid and sustainedreduction in terminal complement activity. In all aHUS patients, eculizumab serum concentrations ofapproximately 50 - 100 microgram/mL are sufficient for essentially complete inhibition of terminalcomplement activity.

In aHUS, chronic administration of Soliris resulted in a rapid and sustained reduction in complement-mediated thrombotic microangiopathy.

In refractory gMG patients, uncontrolled terminal complement activation causes membrane attackcomplex (MAC) dependent lysis and C5a-dependent inflammation at the Neuromuscular Junction (NMJ)leading to failure of neuromuscular transmission. Chronic administration of Soliris results in immediate,complete, and sustained inhibition of terminal complement activity (eculizumab serum concentrations ≥116 microgram/ml).

In patients with NMOSD, uncontrolled terminal complement activation caused by autoantibodies against

AQP4 leads to the formation of the MAC and C5a-dependent inflammation which results in astrocytenecrosis and increased permeability of the blood brain barrier, as well as death of the surroundingoligodendrocytes and neurons. Chronic administration of Soliris results in immediate, complete, andsustained inhibition of terminal complement activity (eculizumab serum concentrations ≥ 116microgram/ml).

Clinical efficacy and safety
Paroxysmal Nocturnal Haemoglobinuria

The safety and efficacy of Soliris in PNH patients with haemolysis were assessed in a randomized,double-blind, placebo-controlled 26 week study (C04-001). PNH patients were also treated with Soliris ina single arm 52 week study (C04-002), and in a long term extension study (E05-001). Patients receivedmeningococcal vaccination prior to receipt of Soliris. In all studies, the dose of eculizumab was 600 mgevery 7 ± 2 days for 4 weeks, followed by 900 mg 7 ± 2 days later, then 900 mg every 14 ± 2 days for thestudy duration. Soliris was administered as an intravenous infusion over 25 - 45 minutes (35 minutes ± 10minutes). An observational non-interventional Registry in patients with PNH (M07-001) was also initiatedto characterize the natural history of PNH in untreated patients and the clinical outcomes during Soliristreatment.

In study C04-001 (TRIUMPH) PNH patients with at least 4 transfusions in the prior 12 months, flowcytometric confirmation of at least 10% PNH cells and platelet counts of at least 100,000/microliter wererandomized to either Soliris (n = 43) or placebo (n = 44). Prior to randomization, all patients underwent aninitial observation period to confirm the need for RBC transfusion and to identify the haemoglobinconcentration (the 'set-point') which would define each patient’s haemoglobin stabilization andtransfusion outcomes. The haemoglobin set-point was less than or equal to 9 g/dL in patients withsymptoms and was less than or equal to 7 g/dL in patients without symptoms. Primary efficacy endpointswere haemoglobin stabilization (patients who maintained a haemoglobin concentration above thehaemoglobin set-point and avoid any RBC transfusion for the entire 26 week period) and bloodtransfusion requirement. Fatigue and health-related quality of life were relevant secondary endpoints.

Haemolysis was monitored mainly by the measurement of serum LDH levels, and the proportion of PNH

RBCs was monitored by flow cytometry. Patients receiving anticoagulants and systemic corticosteroids atbaseline continued these medications. Major baseline characteristics were balanced (see Table 2).

In the non-controlled study C04-002 (SHEPHERD), PNH patients with at least one transfusion in the prior24 months and at least 30,000 platelets/microliter received Soliris over a 52-week period. Concomitantmedications included anti-thrombotic agents in 63% of the patients and systemic corticosteroids in 40% ofthe patients. Baseline characteristics are shown in Table 2.

In TRIUMPH, study patients treated with Soliris had significantly reduced (p< 0.001) haemolysisresulting in improvements in anaemia as indicated by increased haemoglobin stabilization and reducedneed for RBC transfusions compared to placebo treated patients (see Table 3). These effects were seenamong patients within each of the three pre-study RBC transfusion strata (4 - 14 units; 15 - 25 units;> 25 units). After 3 weeks of Soliris treatment, patients reported less fatigue and improved health-relatedquality of life. Because of the study sample size and duration, the effects of Soliris on thrombotic eventscould not be determined. In SHEPHERD study, 96 of the 97 enrolled patients completed the study (onepatient died following a thrombotic event). A reduction in intravascular haemolysis as measured by serum

LDH levels was sustained for the treatment period and resulted in increased transfusion avoidance, areduced need for RBC transfusion and less fatigue. See Table 3.

From the 195 patients that originated in C04-001, C04-002 and other initial studies, Soliris-treated PNHpatients were enrolled in a long term extension study (E05-001). All patients sustained a reduction inintravascular haemolysis over a total Soliris exposure time ranging from 10 to 54 months. There werefewer thrombotic events with Soliris treatment than during the same period of time prior to treatment.

However, this finding was shown in non-controlled clinical trials.

The PNH registry (M07-001) was used to evaluate the efficacy of Soliris in PNH patients with no historyof RBC transfusion. These patients had high disease activity as defined by elevated haemolysis (LDH≥1.5x ULN) and the presence of related clinical symptom(s): fatigue, haemoglobinuria, abdominal pain,shortness of breath (dyspnoea), anaemia (haemoglobin <100 g/L), major adverse vascular event (includingthrombosis), dysphagia, or erectile dysfunction.

In the PNH Registry, patients treated with Soliris were observed to have a reduction in haemolysis andassociated symptoms. At 6 months, patients treated with Soliris with no history of RBC transfusion hadsignificantly (p<0.001) reduced LDH levels (median LDH of 305 U/L; Table 4). Furthermore, 74% of thepatients without a history of transfusion and treated with Soliris experienced clinically meaningfulimprovements in FACIT-Fatigue score (i.e., increase by 4 points or more) and 84% in EORTC fatiguescore (i.e., decrease by 10 points or more).

Atypical Haemolytic Uremic Syndrome

Data from 100 patients in four prospective controlled studies, three in adult and adolescent patients (C08-002A/B C08-003A/B, C10-004) one in paediatric and adolescent patients (C10-003 ) and 30 patients inone retrospective study (C09-001r) were used to evaluate the efficacy of Soliris in the treatment of aHUS.

Study C08-002A/B was a prospective, controlled, open-label study which accrued patients in the earlyphase of aHUS with evidence of clinical thrombotic microangiopathy manifestations with platelet count ≤150 x 109/L despite PE/PI, and LDH and serum creatinine above upper limits of normal.

Study C08-003A/B was a prospective, controlled, open-label study which accrued patients with longerterm aHUS without apparent evidence of clinical thrombotic microangiopathy manifestations andreceiving chronic PE/PI (≥1 PE/PI treatment every two weeks and no more than 3 PE/PI treatments/weekfor at least 8 weeks before the first dose). Patients in both prospective studies were treated with Soliris for26 weeks and most patients enrolled into a long-term, open-label extension study. All patients enrolled inboth prospective studies had an ADAMTS-13 level above 5%.

Patients received meningococcal vaccination prior to receipt of Soliris or received prophylactic treatmentwith appropriate antibiotics until 2 weeks after vaccination. In all studies, the dose of Soliris in adult andadolescent aHUS patients was 900 mg every 7 ± 2 days for 4 weeks, followed by 1,200 mg 7 ± 2 dayslater, then 1,200 mg every 14 ± 2 days for the study duration. Soliris was administered as an intravenousinfusion over 35 minutes. The dosing regimen in paediatric patients and adolescents weighing less than40 kg was defined based on a pharmacokinetic (PK) simulation that identified the recommended dose andschedule based on body weight (see section 4.2).

Primary endpoints included platelet count change from baseline in study C08-002A/B and thromboticmicroangiopathy (TMA) event-free status in study C08-003A/B. Additional endpoints included TMAintervention rate, haematologic normalization, complete TMA response, changes in LDH, renal functionand quality of life. TMA-event free status was defined as the absence for at least 12 weeks of thefollowing: decrease in platelet count of > 25% from baseline, PE/PI, and new dialysis. TMA interventionswere defined as PE/PI or new dialysis. Haematologic normalization was defined as normalization ofplatelet counts and LDH levels sustained for ≥2 consecutive measurements for ≥4 weeks. Complete TMAresponse was defined as haematologic normalization and a ≥25% reduction in serum creatinine sustainedin ≥ 2 consecutive measurements for ≥ 4 weeks.

Baseline characteristics are shown in Table 5.

Patients in aHUS Study C08-002 A/B received Soliris for a minimum of 26 weeks. After completion ofthe initial 26-week treatment period, most patients continued to receive Soliris by enrolling into anextension study. In aHUS Study C08-002A/B, the median duration of Soliris therapy wasapproximately100 weeks (range: 2 weeks to 145 weeks).

A reduction in terminal complement activity and an increase in platelet count relative to baseline wereobserved after commencement of Soliris. Reduction in terminal complement activity was observed in allpatients after commencement of Soliris. Table 6 summarizes the efficacy results for aHUS Study C08-002A/B. All rates of efficacy endpoints improved or were maintained through 2 years of treatment.

Complete TMA response was maintained by all responders. When treatment was continued for more than26 weeks, two additional patients achieved and maintained Complete TMA response due to normalizationof LDH (1 patient) and a decrease in serum creatinine (2 patients).

Renal function, as measured by eGFR, was improved and maintained during Soliris therapy. Four of thefive patients who required dialysis at study entry were able to discontinue dialysis for the duration of

Soliris treatment, and one patient developed a new dialysis requirement. Patients reported improvedhealth-related quality of life (QoL).

In aHUS Study C08-002A/B, responses to Soliris were similar in patients with and without identifiedmutations in genes encoding complement regulatory factor proteins.

Patients in aHUS study C08-003A/B received Soliris for a minimum of 26 weeks. After completion of theinitial 26-week treatment period, most patients continued to receive Soliris by enrolling into an extensionstudy. In aHUS Study C08-003A/B, the median duration of Soliris therapy was approximately 114 weeks(range: 26 to 129 weeks). Table 6 summarizes the efficacy results for aHUS Study C08-003A/B.

In aHUS Study C08-003A/B, responses to Soliris were similar in patients with and without identifiedmutations in genes encoding complement regulatory factor proteins. Reduction in terminal complementactivity was observed in all patients after commencement of Soliris. All rates of efficacy endpointsimproved or were maintained through 2 years of treatment. Complete TMA response was maintained byall responders. When treatment was continued for more than 26 weeks, six additional patients achievedand maintained Complete TMA response due to a decrease in serum creatinine. No patient required newdialysis with Soliris. Renal function, as measured by median eGFR, increased during Soliris therapy.

Patients in aHUS Study C10-004 received Soliris for a minimum of 26 weeks. After completion of theinitial 26-week treatment period, most patients elected to continue on chronic dosing.

Reduction in terminal complement activity and an increase in platelet count relative to baseline wereobserved after commencement of Soliris. Soliris reduced signs of complement-mediated TMA activity, asshown by an increase in mean platelet counts from baseline to 26 weeks. In aHUS C10-004, mean (±SD)platelet count increased from 119 ± 66 x109/L at baseline to 200 ± 84 x109/L by one week; this effect wasmaintained through 26 weeks (mean platelet count (±SD) at week 26: 252 ± 70 x109/L). Renal function, asmeasured by eGFR, was improved during Soliris therapy. Twenty of the 24 patients who required dialysisat baseline were able to discontinue dialysis during Soliris treatment.

Longer term treatment with Soliris (median 52 weeks ranging from 15 to 126 weeks) was associated withan increased rate of clinically meaningful improvements in adult patients with aHUS. When Soliristreatment was continued for more than 26 weeks, three additional patients (63% of patients in total)achieved Complete TMA response and four additional patients (98% of patients in total) achievedhematologic normalization. At the last evaluation, 25 of 41 patients (61%) achieved eGFR improvementof ≥ 15 mL/min/1.73 m2 from baseline.

Refractory Generalized Myasthenia Gravis

Data from 139 patients in two prospective controlled studies (Studies C08-001 and ECU-MG-301), andone open-label extension trial (Study ECU-MG-302) were used to evaluate the efficacy of Soliris in thetreatment of patients with refractory gMG.

Study ECU-MG-301 (REGAIN) was a 26-week double-blind, randomized, placebo-controlled, multi-center Phase 3 study of Soliris in patients who had failed previous therapies and remain symptomatic. Onehundred and eighteen (118) of the 125 (94%) patients completed the 26-week treatment period and117 (94%) patients subsequently enrolled in Study ECU-MG-302, an open-label, multi-center long-termsafety and efficacy extension study in which all patients received Soliris treatment.

In Study ECU-MG-301, gMG patients with a positive serologic test for anti-AChR antibodies, MGFA(Myasthenia Gravis Foundation of America) clinical classification class II to IV and MG-ADL total score≥6 were randomized to either Soliris (n = 62) or placebo (n = 63). All patients included in the trial wererefractory gMG patients and met the following predefined criteria:

1) Failed treatment for at least one year with 2 or more immunosuppressant therapies (either incombination or as monotherapy), ie, patients continued to have impairment in activities of daily livingdespite immunosuppressant therapies

OR2) Failed at least one immunosuppressant therapy and required chronic plasma exchange or IVIg tocontrol symptoms, ie, patients require PE or IVIg on a regular basis for the management of muscleweakness at least every 3 months over previous 12 months.

Patients received meningococcal vaccination prior to initiating treatment with Soliris or receivedprophylactic treatment with appropriate antibiotics until 2 weeks after vaccination. In Studies ECU-MG-301 and ECU-MG-302, the dose of Soliris in adult refractory gMG patients was 900 mg every 7 ± 2 daysfor 4 weeks, followed by 1200 mg at Week 5± 2 days, then 1,200 mg every 14 ± 2 days for the studyduration. Soliris was administered as an intravenous infusion over 35 minutes.

The primary endpoint for Study ECU-MG-301 was the change from baseline in the MG Activities of

Daily Living Profile (MG-ADL - a patient reported outcome measure validated in gMG) total score at

Week 26. The primary analysis of the MG-ADL was a Worst-Rank ANCOVA with a mean rank of 56.6for Soliris and 68.3 for placebo, based on 125 study patients (p=0.0698).

The key secondary endpoint was the change from baseline in the Quantitative MG Scoring System (QMG- a physician reported outcome measure validated in gMG) total score at Week 26. The primary analysisof the QMG was a Worst-Rank ANCOVA with a mean rank of 54.7 for Soliris and 70.7 for placebo,based on 125 study patients (p=0.0129).

In Study ECU-MG-301, a clinical responder in the MG-ADL total score was defined as having at least a3-point improvement. The proportion of clinical responders at Week 26 with no rescue therapy was 59.7%on Soliris compared with 39.7% on placebo (p=0.0229).

In Study ECU-MG-301, a clinical responder in the QMG total score was defined as having at least a 5-pointimprovement. The proportion of clinical responders at Week 26 with no rescue therapy was 45.2% on Soliriscompared with 19% on placebo (p=0.0018).

Table 11 presents an overview of the patients reporting clinical deterioration and patients requiring rescuetherapy over the 26 weeks.

Of the 125 patients enrolled in ECU-MG-301, 117 patients subsequently enrolled in a long-term extensionstudy (Study ECU-MG-302), in which all received Soliris. Patients that were previously treated with Solirisin Study ECU-MG-301 continued to demonstrate a sustained effect of Soliris on all measures (MG-ADL,

QMG, MGC and MG-QoL15) over an additional 130 weeks of treatment with eculizumab in Study ECU-

MG-302. For patients who received placebo in Study ECU-MG-301 (placebo/eculizumab arm of Study

ECU-MG-302), improvement occurred after initiating treatment with eculizumab and was maintained formore than 130 weeks in Study ECU-MG-302. Figure 1 presents the change from baseline in both MG-ADL(A) and QMG (B) after 26 weeks of treatment in Study ECU-MG-301 and after 130 weeks of treatment (n= 80 patients) in Study ECU-MG-302.

In Study ECU-MG-302, physicians had the option to adjust background immunosuppressant therapies. Inthis setting, 65.0% of patients decreased their daily dose of at least 1 immunosuppressive therapy (IST);43.6% of patients stopped an existing IST. The most common reason for change in IST therapy wasimprovement in MG symptoms.

Twenty-two (22) (17.6%) elderly refractory gMG patients (> 65 years of age) were treated with Soliris inthe clinical trials. No substantial differences were seen in safety and efficacy related to age.

Neuromyelitis Optica Spectrum Disorder

Data from 143 patients in one controlled study (Study ECU-NMO-301) and from 119 patients whocontinued in one open-label extension trial (Study ECU-NMO-302) were used to evaluate the efficacy andsafety of Soliris in the treatment of patients with NMOSD.

Study ECU-NMO-301 was a double-blind, randomized, placebo-controlled, multi-center, Phase 3 study of

Soliris in patients with NMOSD.

In Study ECU-NMO-301, patients with NMOSD with a positive serologic test for anti-AQP4 antibodies, ahistory of at least 2 relapses in last 12 months or 3 relapses in the last 24 months with at least 1 relapse inthe 12 months prior to screening and an Expanded Disability Status Scale (EDSS) score ≤ 7, wererandomized 2:1 to either Soliris (n = 96) or placebo (n = 47). Patients were permitted to receivebackground immunosuppressant therapies at stable dose during the study, with the exclusion of rituximaband mitoxantrone.

Patients either received meningococcal vaccination at least 2 weeks prior to initiating treatment with

Soliris or received prophylactic treatment with appropriate antibiotics until 2 weeks after vaccination. Inthe eculizumab NMOSD clinical development program, the dose of Soliris in adult patients with NMOSDwas 900 mg every 7 ± 2 days for 4 weeks, followed by 1200 mg at Week 5 ± 2 days, then 1200 mg every14 ± 2 days for the study duration. Soliris was administered as an intravenous infusion over 35 minutes.

The majority (90.9%) of patients were female. Approximately half were White (49.0%). The median ageat first dose of study drug was 45 years.

Compared to placebo-treated patients, Soliris-treated patients had reduced annualized rates ofhospitalizations (0.04 for Soliris versus 0.31 for placebo), of intravenous corticosteroid administrations totreat acute relapses (0.07 for Soliris versus 0.42 for placebo), and of plasma exchange treatments (0.02 for

Soliris versus 0.19 for placebo).

The final analysis of Study ECU-NMO-302 demonstrates a significant and clinically meaningful reductionin On-trial ARR (as determined by the treating Physician) on eculizumab treatment, based on the median(min, max) change (-1.825 [-6.38, 1.02], p<0.0001) from historical ARR (24 months prior to screening in

Study ECU-NMO-301).

In Study ECU-NMO-302, physicians had the option to adjust background immunosuppressant therapies. Inthis setting, the most common change in immunosuppressant therapy was decreased immunosuppressanttherapy dose, which occurred in 21.0% of patients. Further, 15.1% of patients stopped an existing IST.

Soliris (eculizumab) has not been studied for the treatment of acute relapses in NMOSD patients.

Paediatric population
Paroxysmal Nocturnal Haemoglobinuria

A total of 7 PNH paediatric patients, with a median weight of 57.2 kg (range of 48.6 to 69.8 kg) and agedfrom 11 to 17 years (median age : 15.6 years), received Soliris in study M07-005.

Treatment with eculizumab at the proposed dosing regimen in the paediatric population was associatedwith a reduction of intravascular haemolysis as measured by serum LDH level. It also resulted in a markeddecrease or elimination of blood transfusions, and a trend towards an overall improvement in generalfunction. The efficacy of eculizumab treatment in paediatric PNH patients appears to be consistent withthat observed in adult PNH patients enrolled in PNH pivotal Studies (C04-001 and C04-002) (Table 3 and14).

Atypical Haemolytic Uremic Syndrome

A total of 15 paediatric patients (aged 2 months to 12 years) received Soliris in aHUS Study C09-001r.

Forty seven percent of patients had an identified complement regulatory factor mutation or auto-antibody.

The median time from aHUS diagnosis to first dose of Soliris was 14 months (range <1, 110 months). Themedian time from current thrombotic microangiopathy manifestation to first dose of Soliris was 1 month(range <1 to 16 months). The median duration of Soliris therapy was 16 weeks (range 4 to 70 weeks) forchildren < 2 years of age (n=5) and 31 weeks (range 19 to 63 weeks) for children 2 to <12 years of age(n=10).

Overall, the efficacy results for these paediatric patients appeared consistent with what was observed inpatients enrolled in aHUS pivotal Studies C08-002 and C08-003 (Table 6). No paediatric patient requirednew dialysis during treatment with Soliris.

A total of 22 paediatric and adolescents patients (aged 5 months to 17 years) received Soliris inaHUS Study C10-003.

In Study C10-003, patients who enrolled in the study were required to have a platelet count < lower limitof normal range (LLN), evidence of haemolysis such as an elevation in serum LDH above the upper limitsof normal and serum creatinine level ≥97 percentile for age without the need for chronic dialysis. Themedian patient age was 6.5 years (range: 5 months to 17 years). Patients enrolled in aHUS C10-003 hadan ADAMTS-13 level above 5%. Fifty percent of patients had an identified complement regulatory factormutation or auto-antibody. A total of 10 patients received PE/PI prior to eculizumab. Table 17 summarizesthe key baseline clinical and disease-related characteristics of patients enrolled in aHUS Study C10-003.

Patients in aHUS C10-003 received Soliris for a minimum of 26 weeks. After completion of the initial 26-week treatment period, most patients elected to continue on chronic dosing. Reduction in terminalcomplement activity was observed in all patients after commencement of Soliris. Soliris reduced signs ofcomplement-mediated TMA activity, as shown by an increase in mean platelet counts from baseline to 26weeks. The mean (±SD) platelet count increased from 88 ± 42 x109/L at baseline to 281 ± 123 x109/L byone week; this effect was maintained through 26 weeks (mean platelet count (±SD) at week 26: 293 ± 106x109/L). Renal function, as measured by eGFR, was improved during Soliris therapy. Nine of the 11patients who required dialysis at baseline no longer required dialysis after Study Day 15 of eculizumabtreatment. Responses were similar across all ages from 5 months to 17 years of age. In aHUS C10-003,responses to Soliris were similar in patients with and without identified mutations in genes encodingcomplement regulatory factor proteins or auto-antibodies to factor H.

Longer term treatment with Soliris (median 55 weeks ranging from 1day to 107 weeks) was associatedwith an increased rate of clinically meaningful improvements in paediatric and adolescent patients withaHUS. When Soliris treatment was continued for more than 26 weeks, one additional patient (68% ofpatients in total) achieved Complete TMA Response and two additional patients (91% of patients in total)achieved hematologic normalization. At the last evaluation, 19 of 22 patients (86%) achieved eGFRimprovement of ≥ 15 mL/min/1.73 m2 from baseline. No patient required new dialysis with Soliris.

Refractory Generalized Myasthenia Gravis

A total of 11 paediatric patients with refractory gMG received Soliris in study ECU-MG-303. The median(range) body weight of the treated patients was 59.7 kg (37.2 to 91.2 kg) at baseline, and the median(range) age of 15 years (12 to 17 years) at screening. All patients included in the study were patients withrefractory gMG who had one or more of the following:

1. Failed treatment ≥ 1 year with at least 1 IST, defined as: (i) Persistent weakness with impairment ofactivities of daily living, or (ii) Myasthenia gravis exacerbation and/or crisis while on treatment,or (iii) Intolerance to ISTs due to side effect or comorbid condition(s).

2. Require maintenance PE or IVIg to control symptoms (ie, patients who require PE or IVIg on aregular basis for the management of muscle weakness at least every 3 months over the last12 months prior to screening).

The baseline characteristics of the paediatric patients with refractory gMG enrolled in study ECU-MG-303are outlined in Table 19.

The primary endpoint of study ECU-MG-303 was the change from baseline in the QMG total score overtime regardless of rescue therapy. Paediatric patients treated with Soliris demonstrated a statisticallysignificant improvement from baseline in QMG total score throughout the Primary Evaluation Treatment

Period of 26 weeks. The results for the primary and main secondary endpoint in study ECU-MG-303 areincluded in Table 20.

The efficacy of Soliris treatment in paediatric patients with refractory gMG was consistent with thatobserved in adult patients with refractory gMG enrolled in the pivotal study ECU-MG-301 (Table 10).

In study ECU-MG-303, a clinical responder in the QMG and MG-ADL total scores was defined as havingat least a 5-point improvement and 3-point improvement from baseline, respectively. The proportion ofclinical responders in the QMG and MG-ADL total scores at Week 26 regardless of rescue therapy was 70%and 50%, respectively. The 10 patients who completed their visit at Week 26 achieved improved status of

MGFA Post-Interventional Status (MGFA-PIS) at Week 26. Seven (70%) patients achieved minimalmanifestation of refractory gMG at Week 26.

An event of clinical deterioration (MG crisis) was observed in 1 patient (9.1%) during the

Primary Evaluation Treatment Period requiring rescue therapy (PE) which was administeredbetween the Week 22 and Week 24 study visits. As a result and due to physician decision, thispatient did not have QMG, MG-ADL or other efficacy assessments after Week 20 and did notenter the extension period.Another 2 patients experienced clinical deteriorations (MG crisis)during the Extension Period requiring rescue therapy (PE and IVIg for clinical deterioration inone case and IVIg and 2 supplemental treatments of eculizumab in the second case).

During the entire study period in paediatric patients with refractory gMG (study ECU-MG-303), 4 out of11 patients (36.4%) decreased their daily dose of IST or anticholinesterase therapy due to improved MGsymptoms. An additional patient (9.1%) decreased and subsequently increased their daily dose during the

Extension Period due to improved and worsened MG symptoms respectively and 1 patient started a newcorticosteroid treatment due to worsened MG symptoms.

Long-term efficacy

All patients who completed the Primary Treatment Period (N=10) entered the Extension Period of up to208 weeks of treatment. Only two patients completed the Extension Period. Eight participantsdiscontinued the study during the Extension Period including 4 participants transitioned to eithercommercially available Soliris or Ultomiris or transferred to another ongoing Ultomiris paediatric study.

Patients consistently maintained the response through the study, which was of similar magnitude to thatreported to during the initial treatment period.

5.2 Pharmacokinetic properties

Pharmacokinetics and Drug Metabolism

Biotransformation

Human antibodies undergo endocytotic digestion in the cells of the reticuloendothelial system.

Eculizumab contains only naturally occurring amino acids and has no known active metabolites. Humanantibodies are predominately catabolized by lysosomal enzymes to small peptides and amino acids.

Elimination

No specific studies have been performed to evaluate the hepatic, renal, lung, or gastrointestinal routes ofexcretion/elimination for Soliris. In normal kidneys, antibodies are not excreted and are excluded fromfiltration by their size.

Pharmacokinetic/pharmacodynamic relationship(s)

In 40 patients with PNH, a 1-compartmental model was used to estimate pharmacokinetic parameters aftermultiple doses. Mean clearance was 0.31 ± 0.12 mL/hr/kg, mean volume of distribution was 110.3 ±17.9 mL/kg, and mean elimination half-life was 11.3 ± 3.4 days. The steady state is achieved by 4 weeksusing the PNH adult dosing regimen.

In PNH patients, pharmacodynamic activity correlates directly with eculizumab serum concentrations andmaintenance of trough levels above ≥ 35 microgram/mL results in essentially complete blockade ofhaemolytic activity in the majority of PNH patients.

A second population PK analysis with a standard 1 compartmental model was conducted on the multipledose PK data from 37 aHUS patients receiving the recommended Soliris regimen in studies C08-002A/Band C08-003A/B. In this model, the clearance of Soliris for a typical aHUS patient weighing 70 kg was0.0139 L/hr and the volume of distribution was 5.6 L. The elimination half-life was 297 h (approximately12.4 days).

The second population PK model was applied to the multiple dose PK data from 22 paediatric aHUSpatients receiving the recommended Soliris regimen in aHUS C10-003. The clearance and volume ofdistribution of Soliris are weight dependent, which forms the basis for a weight categorical based doseregimen in paediatric patients (see section 4.2). Clearance values of Soliris in paediatric aHUS patientswere 10.4, 5.3, and 2.2 mL/hr with body weight of 70, 30, and 10 kg, respectively; and the correspondingvolume of distribution values were 5.23, 2.76, and 1.21 L, respectively. The corresponding eliminationhalf-life remained almost unchanged within a range of 349 to 378 h (approximately 14.5 to 15.8 days).

The clearance and half-life of eculizumab were also evaluated during plasma exchange interventions.

Plasma exchange resulted in an approximately 50% decline in eculizumab concentrations following a1 hour intervention and the elimination half-life of eculizumab was reduced to 52.4 hours. Supplementaldosing is recommended when Soliris is administered to aHUS patients receiving plasma infusion orexchange (see section 4.2).

All aHUS patients treated with Soliris when administered as recommended demonstrated rapid andsustained reduction in terminal complement activity. In aHUS patients, pharmacodynamic activitycorrelates directly with eculizumab serum concentrations and maintenance of trough levels ofapproximately 50-100 microgram/ml results in essentially complete blockade of terminal complementactivity in all aHUS patients.

PK parameters are consistent across PNH, aHUS, refractory gMG and NMOSD patient populations.

Pharmacodynamic activity measured by free C5 concentrations of <0.5 ug/mL, is correlated withessentially complete blockade of terminal complement activity in PNH, aHUS, refractory gMG and

NMOSD patients.

Special Populations

Dedicated studies have not been conducted to evaluate the pharmacokinetics of Soliris in special patientpopulations identified by gender, race, age (geriatric), or the presence of renal or hepatic impairment.

Population PK (PopPK) analysis on data collected across studies in PNH, aHUS, gMG and NMOSDpatients showed that gender, race, age (geriatric), or the presence of renal or hepatic impairment functiondo not influence the PK of eculizumab.

Paediatric population

The pharmacokinetics of eculizumab was evaluated in Study M07-005 in PNH paediatric patients (agedfrom 11 to less than 18 years), in Studies C08-002, C08-003, C09-001r and C10-003 in aHUS paediatricpatients (aged 2 months to less than 18 years), and in Study ECU-MG-303 paediatric patients withrefractory gMG (aged from 12 years to less than 18 years) PopPK analysis showed that for PNH, aHUS,refractory gMG, and NMOSD, body weight was a significant covariate requiring body weight-baseddosing for pediatric patients.

5.3 Preclinical safety data

The specificity of eculizumab for C5 in human serum was evaluated in two in vitro studies.

The tissue cross-reactivity of eculizumab was evaluated by assessing binding to a panel of 38 humantissues. C5 expression in the human tissue panel examined in this study is consistent with publishedreports of C5 expression, as C5 has been reported in smooth muscle, striated muscle, and renal proximaltubular epithelium. No unexpected tissue cross-reactivity was observed.

Animal reproduction studies have not been conducted with eculizumab due to lack of pharmacologicactivity in non-human species.

In a 26 week toxicity study performed in mice with a surrogate antibody directed against murine C5,treatment did not affect any of the toxicity parameters examined. Haemolytic activity during the course ofthe study was effectively blocked in both female and male mice.

No clear treatment-related effects or adverse effects were observed in reproductive toxicology studies inmice with a surrogate terminal complement inhibitory antibody, which was utilized to assess thereproductive safety of C5 blockade. These studies included assessment of fertility and early embryonicdevelopment, developmental toxicity, and pre and post-natal development.

When maternal exposure to the antibody occurred during organogenesis, two cases of retinal dysplasia andone case of umbilical hernia were observed among 230 offspring born to mothers exposed to the higherantibody dose (approximately 4 times the maximum recommended human Soliris dose, based on a bodyweight comparison); however, the exposure did not increase foetal loss or neonatal death.

No animal studies have been conducted to evaluate the genotoxic and carcinogenic potential ofeculizumab.
