Plaque psoriasis

Pyzchiva is indicated for the treatment of moderate to severe plaque psoriasis in adults who failed torespond to, or who have a contraindication to, or are intolerant to other systemic therapies includingciclosporin, methotrexate (MTX) or PUVA (psoralen and ultraviolet A) (see section 5.1).

Psoriatic arthritis (PsA)

Pyzchiva, alone or in combination with MTX, is indicated for the treatment of active psoriatic arthritisin adult patients when the response to previous non-biological disease-modifying anti-rheumatic drug(DMARD) therapy has been inadequate (see section 5.1).

Crohn’s Disease

Pyzchiva is indicated for the treatment of adult patients with moderately to severely active Crohn’sdisease who have had an inadequate response with, lost response to, or were intolerant to eitherconventional therapy or a TNFα antagonist or have medical contraindications to such therapies.

Pyzchiva is intended for use under the guidance and supervision of physicians experienced in thediagnosis and treatment of conditions for which Pyzchiva is indicated.

Plaque psoriasis

The recommended posology of Pyzchiva is an initial dose of 45 mg administered subcutaneously,followed by a 45 mg dose 4 weeks later, and then every 12 weeks thereafter.

Consideration should be given to discontinuing treatment in patients who have shown no response upto 28 weeks of treatment.

Patients with body weight > 100 kg

For patients with a body weight > 100 kg the initial dose is 90 mg administered subcutaneously,followed by a 90 mg dose 4 weeks later, and then every 12 weeks thereafter. In these patients, 45 mgwas also shown to be efficacious. However, 90 mg resulted in greater efficacy. (see section 5.1,

Table 4).

Psoriatic arthritis (PsA)

The recommended posology of Pyzchiva is an initial dose of 45 mg administered subcutaneously,followed by a 45 mg dose 4 weeks later, and then every 12 weeks thereafter. Alternatively, 90 mg maybe used in patients with a body weight > 100 kg.

Consideration should be given to discontinuing treatment in patients who have shown no response upto 28 weeks of treatment.

No dose adjustment is needed for elderly patients (see section 4.4).

Ustekinumab has not been studied in these patient populations. No dose recommendations can bemade.

The safety and efficacy of ustekinumab in children with psoriasis less than 6 years of age or inchildren with psoriatic arthritis less than 18 years of age have not yet been established. The pre-filledpen has not been studied in the paediatric population and is not recommended for use in paediatricpatients. See section 4.2 of the pre-filled syringe SmPC for posology and method of administration inpaediatic patients 6 years and older with psoriasis.

Crohn’s Disease

In the treatment regimen, the first dose of Pyzchiva is administered intravenously. For the posology ofthe intravenous dosing regimen, see section 4.2 of the Pyzchiva 130 mg Concentrate for solution forinfusion SmPC.

The first subcutaneous administration of 90 mg Pyzchiva should take place at week 8 after theintravenous dose. After this, dosing every 12 weeks is recommended.

Patients who have not shown adequate response at 8 weeks after the first subcutaneous dose, mayreceive a second subcutaneous dose at this time (see section 5.1).

Patients who lose response on dosing every 12 weeks may benefit from an increase in dosingfrequency to every 8 weeks (see section 5.1, section 5.2).

Patients may subsequently be dosed every 8 weeks or every 12 weeks according to clinical judgment(see section 5.1).

Consideration should be given to discontinuing treatment in patients who show no evidence oftherapeutic benefit 16 weeks after the IV induction dose or 16 weeks after switching to the 8-weeklymaintenance dose.

Immunomodulators and/or corticosteroids may be continued during treatment with Pyzchiva. Inpatients who have responded to treatment with Pyzchiva, corticosteroids may be reduced ordiscontinued in accordance with standard of care.

In Crohn’s disease, if therapy is interrupted, resumption of treatment with subcutaneous dosing every8 weeks is safe and effective.

No dose adjustment is needed for elderly patients (see section 4.4).

Ustekinumab has not been studied in these patient populations. No dose recommendations can bemade.

The safety and efficacy of ustekinumab in treatment of Crohn’s disease in children less than 18 yearshave not yet been established. No data are available.

Pyzchiva 45 mg and 90 mg pre-filled pens are for subcutaneous injection only. If possible, areas of theskin that show psoriasis should be avoided as injection sites.

After proper training in subcutaneous injection technique, patients or their caregivers may inject

Pyzchiva if a physician determines that it is appropriate. However, the physician should ensureappropriate follow-up of patients. Patients or their caregivers should be instructed to inject theprescribed amount of Pyzchiva according to the directions provided in the package leaflet.

Comprehensive instructions for administration are given in the package leaflet.

For further instructions on preparation and special precautions for handling, see section 6.6.

Hypersensitivity to the active substance or to any of the excipients listed in section 6.1.

Clinically important, active infection (e.g. active tuberculosis; see section 4.4).

In order to improve the traceability of biological medicinal products, the tradename and the batchnumber of the administered product should be clearly recorded.

Ustekinumab may have the potential to increase the risk of infections and reactivate latent infections.

In clinical studies and a post-marketing observational study in patients with psoriasis, serious bacterial,fungal, and viral infections have been observed in patients receiving ustekinumab (see section 4.8).

Opportunistic infections including reactivation of tuberculosis, other opportunistic bacterial infections(including atypical mycobacterial infection, listeria meningitis, pneumonia legionella, andnocardiosis), opportunistic fungal infections, opportunistic viral infections (including encephalitiscaused by herpes simplex 2), and parasitic infections (including ocular toxoplasmosis) have beenreported in patients treated with ustekinumab.

Caution should be exercised when considering the use of ustekinumab in patients with a chronicinfection or a history of recurrent infection (see section 4.3).

Prior to initiating treatment with ustekinumab, patients should be evaluated for tuberculosis infection.ustekinumab must not be given to patients with active tuberculosis (see section 4.3). Treatment oflatent tuberculosis infection should be initiated prior to administering ustekinumab. Anti-tuberculosistherapy should also be considered prior to initiation of ustekinumab in patients with a history of latentor active tuberculosis in whom an adequate course of treatment cannot be confirmed. Patientsreceiving ustekinumab should be monitored closely for signs and symptoms of active tuberculosisduring and after treatment.

Patients should be instructed to seek medical advice if signs or symptoms suggestive of an infectionoccur. If a patient develops a serious infection, the patient should be closely monitored andustekinumab should not be administered until the infection resolves.

Immunosuppressants like ustekinumab have the potential to increase the risk of malignancy. Somepatients who received ustekinumab in clinical studies and in a post-marketing observational study inpatients with psoriasis developed cutaneous and non-cutaneous malignancies (see section 4.8). Therisk of malignancy may be higher in psoriasis patients who have been treated with other biologicsduring the course of their disease.

No studies have been conducted that include patients with a history of malignancy or that continuetreatment in patients who develop malignancy while receiving ustekinumab. Thus, caution should beexercised when considering the use of ustekinumab in these patients.

All patients, in particular those greater than 60 years of age, patients with a medical history ofprolonged immunosuppressant therapy or those with a history of PUVA treatment, should bemonitored for the appearance of skin cancer (see section 4.8).

Systemic and respiratory hypersensitivity reactions

Systemic

Serious hypersensitivity reactions have been reported in the postmarketing setting, in some casesseveral days after treatment. Anaphylaxis and angioedema have occurred. If an anaphylactic or otherserious hypersensitivity reaction occurs, appropriate therapy should be instituted and administration ofustekinumab should be discontinued (see section 4.8).

Respiratory

Cases of allergic alveolitis, eosinophilic pneumonia, and non-infectious organising pneumonia havebeen reported during post-approval use of ustekinumab. Clinical presentations included cough,dyspnoea, and interstitial infiltrates following one to three doses. Serious outcomes have includedrespiratory failure and prolonged hospitalisation. Improvement has been reported after discontinuationof ustekinumab and also, in some cases, administration of corticosteroids. If infection has beenexcluded and diagnosis is confirmed, discontinue ustekinumab and institute appropriate treatment (seesection 4.8).

Cardiovascular events including myocardial infarction and cerebrovascular accident have beenobserved in patients with psoriasis exposed to ustekinumab in a post-marketing observational study.

Risk factors for cardiovascular disease should be regularly assessed during treatment withustekinumab.

It is recommended that live viral or live bacterial vaccines (such as Bacillus of Calmette and Guérin(BCG)) should not be given concurrently with ustekinumab. Specific studies have not been conductedin patients who had recently received live viral or live bacterial vaccines. No data are available on thesecondary transmission of infection by live vaccines in patients receiving ustekinumab. Before liveviral or live bacterial vaccination, treatment with ustekinumab should be withheld for at least 15 weeksafter the last dose and can be resumed at least 2 weeks after vaccination. Prescribers should consult the

Summary of Product Characteristics for the specific vaccine for additional information and guidanceon concomitant use of immunosuppressive agents post-vaccination.

Administration of live vaccines (such as the BCG vaccine) to infants exposed in utero to ustekinumabis not recommended for twelve months following birth or until ustekinumab infant serum levels areundetectable (see sections 4.5 and 4.6). If there is a clear clinical benefit for the individual infant,administration of a live vaccine might be considered at an earlier timepoint, if infant ustekinumabserum levels are undetectable.

Patients receiving ustekinumab may receive concurrent inactivated or non-live vaccinations.

Long term treatment with ustekinumab does not suppress the humoral immune response topneumococcal polysaccharide or tetanus vaccines (see section 5.1).

Concomitant immunosuppressive therapy

In psoriasis studies, the safety and efficacy of ustekinumab in combination with immunosuppressants,including biologics, or phototherapy have not been evaluated. In psoriatic arthritis studies,concomitant MTX use did not appear to influence the safety or efficacy of ustekinumab. In Crohn’sdisease and ulcerative colitis studies, concomitant use of immunosuppressants or corticosteroids didnot appear to influence the safety or efficacy of ustekinumab. Caution should be exercised whenconsidering concomitant use of other immunosuppressants and ustekinumab or when transitioningfrom other immunosuppressive biologics (see section 4.5).

Immunotherapy

Ustekinumab has not been evaluated in patients who have undergone allergy immunotherapy. It is notknown whether ustekinumab may affect allergy immunotherapy.

Serious skin conditions

In patients with psoriasis, exfoliative dermatitis has been reported following ustekinumab treatment(see section 4.8). Patients with plaque psoriasis may develop erythrodermic psoriasis, with symptomsthat may be clinically indistinguishable from exfoliative dermatitis, as part of the natural course oftheir disease. As part of the monitoring of the patient’s psoriasis, physicians should be alert forsymptoms of erythrodermic psoriasis or exfoliative dermatitis. If these symptoms occur, appropriatetherapy should be instituted. Ustekinumab should be discontinued if a drug reaction is suspected.

Lupus-related conditions

Cases of lupus-related conditions have been reported in patients treated with ustekinumab, includingcutaneous lupus erythematosus and lupus-like syndrome. If lesions occur, especially in sun exposedareas of the skin or if accompanied by arthralgia, the patient should seek medical attention promptly. Ifthe diagnosis of a lupus-related condition is confirmed, ustekinumab should be discontinued andappropriate treatment initiated.

No overall differences in efficacy or safety in patients age 65 and older who received ustekinumabwere observed compared to younger patients in clinical studies in approved indications, however thenumber of patients aged 65 and older is not sufficient to determine whether they respond differentlyfrom younger patients. Because there is a higher incidence of infections in the elderly population ingeneral, caution should be used in treating the elderly.

Live vaccines should not be given concurrently with ustekinumab.

Administration of live vaccines (such as the BCG vaccine) to infants exposed in utero to ustekinumabis not recommended for twelve months following birth or until ustekinumab infant serum levels areundetectable (see sections 4.4 and 4.6). If there is a clear clinical benefit for the individual infant,administration of a live vaccine might be considered at an earlier timepoint, if infant ustekinumabserum levels are undetectable.

No interaction studies have been performed in humans. In the population pharmacokinetic analyses ofthe phase 3 studies, the effect of the most frequently used concomitant medicinal products in patientswith psoriasis (including paracetamol, ibuprofen, acetylsalicylic acid, metformin, atorvastatin,levothyroxine) on pharmacokinetics of ustekinumab was explored. There were no indications of aninteraction with these concomitantly administered medicinal products. The basis for this analysis wasthat at least 100 patients (> 5% of the studied population) were treated concomitantly with thesemedicinal products for at least 90% of the study period. The pharmacokinetics of ustekinumab was notimpacted by concomitant use of MTX, NSAIDs, 6-mercaptopurine, azathioprine and oralcorticosteroids in patients with psoriatic arthritis, Crohn’s disease or ulcerative colitis, or priorexposure to anti-TNFα agents, in patients with psoriatic arthritis or Crohn’s disease or by priorexposure to biologics (i.e. anti-TNFα agents and/or vedolizumab) in patients with ulcerative colitis.

The results of an in vitro study do not suggest the need for dose adjustments in patients who arereceiving concomitant CYP450 substrates (see section 5.2).

In psoriasis studies, the safety and efficacy of ustekinumab in combination with immunosuppressants,including biologics, or phototherapy have not been evaluated. In psoriatic arthritis studies,concomitant MTX use did not appear to influence the safety or efficacy of ustekinumab. In Crohn’sdisease and ulcerative colitis studies, concomitant use of immunosuppressants or corticosteroids didnot appear to influence the safety or efficacy of ustekinumab (see section 4.4).

Women of childbearing potential should use effective methods of contraception during treatment andfor at least 15 weeks after treatment.

Data from a moderate number of prospectively collected pregnancies following exposure toustekinumab with known outcomes, including more than 450 pregnancies exposed during the firsttrimester, do not indicate an increased risk of major congenital malformations in the newborn.

Animal studies do not indicate direct or indirect harmful effects with respect to pregnancy,embryonic/foetal development, parturition or postnatal development (see section 5.3).

However, the available clinical experience is limited. As a precautionary measure, it is preferable toavoid the use of ustekinumab in pregnancy.

Ustekinumab crosses the placenta and has been detected in the serum of infants born to female patientstreated with ustekinumab during pregnancy. The clinical impact of this is unknown, however, the riskof infection in infants exposed in utero to ustekinumab may be increased after birth.

Administration of live vaccines (such as the BCG vaccine) to infants exposed in utero to ustekinumabis not recommended for twelve months following birth or until ustekinumab infant serum levels areundetectable (see sections 4.4 and 4.5). If there is a clear clinical benefit for the individual infant,administration of a live vaccine might be considered at an earlier timepoint, if infant ustekinumabserum levels are undetectable.

Limited data from published literature suggests that ustekinumab is excreted in human breast milk invery small amounts. It is not known if ustekinumab is absorbed systemically after ingestion. Becauseof the potential for adverse reactions in nursing infants from ustekinumab, a decision on whether todiscontinue breast-feeding during treatment and up to 15 weeks after treatment or to discontinuetherapy with ustekinumab must be made taking into account the benefit of breast-feeding to the childand the benefit of ustekinumab therapy to the woman.

The effect of ustekinumab on human fertility has not been evaluated (see section 5.3).

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

The most common adverse reactions (> 5%) in controlled periods of the adult psoriasis, psoriaticarthritis, Crohn’s disease and ulcerative colitis clinical studies with ustekinumab were nasopharyngitisand headache. Most were considered to be mild and did not necessitate discontinuation of studytreatment. The most serious adverse reaction that has been reported for ustekinumab is serioushypersensitivity reactions including anaphylaxis (see section 4.4). The overall safety profile wassimilar for patients with psoriasis, psoriatic arthritis, Crohn’s disease and ulcerative colitis.

The safety data described below reflect exposure in adults to ustekinumab in 14 phase 2 andphase 3 studies in 6,709 patients (4,135 with psoriasis and/or psoriatic arthritis, 1,749 with Crohn’sdisease and 825 patients with ulcerative colitis). This includes exposure to ustekinumab in thecontrolled and non-controlled periods of the clinical studies for at least 6 months or 1 year (4,577 and3,253 patients respectively with psoriasis, psoriatic arthritis, Crohn’s disease or ulcerative colitis) andexposure for at least 4 or 5 years (1,482 and 838 patients with psoriasis respectively).

Table 1 provides a list of adverse reactions from adult psoriasis, psoriatic arthritis, Crohn’s disease andulcerative colitis clinical studies as well as adverse reactions reported from post-marketing experience.

The adverse reactions are classified by System Organ Class and frequency, using the followingconvention: Very common (≥ 1/10), Common (≥ 1/100 to < 1/10), Uncommon (≥ 1/1,000 to < 1/100),

In the placebo-controlled studies of patients with psoriasis, psoriatic arthritis, Crohn’s disease andulcerative colitis, the rates of infection or serious infection were similar between ustekinumab-treatedpatients and those treated with placebo. In the placebo-controlled period of these clinical studies, therate of infection was 1.36 per patient-year of follow-up in ustekinumab-treated patients, and 1.34 inplacebo-treated patients. Serious infections occurred at the rate of 0.03 per patient-year of follow-up inustekinumab-treated patients (30 serious infections in 930 patient-years of follow-up) and 0.03 inplacebo-treated patients (15 serious infections in 434 patient-years of follow-up) (see section 4.4).

In the controlled and non-controlled periods of psoriasis, psoriatic arthritis, Crohn’s disease andulcerative colitis clinical studies, representing 11,581 patient-years of exposure in 6,709 patients, themedian follow-up was 1.0 years; 1.1 years for psoriatic disease studies, 0.6 year for Crohn’s diseasestudies and 1.0 years for ulcerative colitis studies. The rate of infection was 0.91 per patient-year offollow-up in ustekinumab-treated patients, and the rate of serious infections was 0.02 per patient-yearof follow-up in ustekinumab-treated patients (199 serious infections in 11,581 patient-years offollow-up) and serious infections reported included pneumonia, anal abscess, cellulitis, diverticulitis,gastroenteritis and viral infections.

In clinical studies, patients with latent tuberculosis who were concurrently treated with isoniazid didnot develop tuberculosis.

In the placebo-controlled period of the psoriasis, psoriatic arthritis, Crohn’s disease and ulcerativecolitis clinical studies, the incidence of malignancies excluding non-melanoma skin cancer was 0.11per 100 patient-years of follow-up for ustekinumab-treated patients (1 patient in 929 patient-years offollow-up) compared with 0.23 for placebo-treated patients (1 patient in 434 patient-years offollow-up). The incidence of non-melanoma skin cancer was 0.43 per 100 patient-years of follow-upfor ustekinumab-treated patients (4 patients in 929 patient-years of follow-up) compared to 0.46 forplacebo-treated patients (2 patients in 433 patient-years of follow-up).

In the controlled and non-controlled periods of psoriasis, psoriatic arthritis, Crohn’s disease andulcerative colitis clinical studies, representing 11,561 patient-years of exposure in 6,709 patients, themedian follow-up was 1.0 years; 1.1 years for psoriatic disease studies, 0.6 year for Crohn’s diseasestudies and 1.0 years for ulcerative colitis studies. Malignancies excluding non-melanoma skin cancerswere reported in 62 patients in 11,561 patient-years of follow-up (incidence of 0.54 per 100 patient-years of follow-up for ustekinumab-treated patients). The incidence of malignancies reported inustekinumab-treated patients was comparable to the incidence expected in the general population(standardised incidence ratio = 0.93 [95% confidence interval: 0.71, 1.20], adjusted for age, genderand race). The most frequently observed malignancies, other than non-melanoma skin cancer, wereprostate, colorectal, melanoma and breast cancers. The incidence of non-melanoma skin cancer was0.49 per 100 patient-years of follow-up for ustekinumab-treated patients (56 patients in11,545 patient-years of follow-up). The ratio of patients with basal versus squamous cell skin cancers(3:1) is comparable with the ratio expected in the general population (see section 4.4).

During the controlled periods of the psoriasis and psoriatic arthritis clinical studies of ustekinumab,rash and urticaria have each been observed in <1% of patients (see section 4.4).

Paediatric patients 6 years and older with plaque psoriasis

The safety of ustekinumab has been studied in two phase 3 studies of paediatric patients with moderateto severe plaque psoriasis. The first study was in 110 patients from 12 to 17 years of age treated for upto 60 weeks and the second study was in 44 patients from 6 to 11 years of age treated for up to56 weeks. In general, the adverse events reported in these two studies with safety data up to 1 yearwere similar to those seen in previous studies in adults with plaque psoriasis.

Reporting suspected adverse reactions after authorisation of the medicinal product is important. Itallows continued monitoring of the benefit/risk balance of the medicinal product. Healthcareprofessionals are asked to report any suspected adverse reactions via the national reporting systemlisted in Appendix V.

Single doses up to 6 mg/kg have been administered intravenously in clinical studies withoutdose-limiting toxicity. In case of overdose, it is recommended that the patient be monitored for anysigns or symptoms of adverse reactions and appropriate symptomatic treatment be institutedimmediately.

Pharmacotherapeutic group: Immunosuppressants, interleukin inhibitors, ATC code: L04AC05.

Ustekinumab is a fully human IgG1κ monoclonal antibody that binds with specificity to the sharedp40 protein subunit of human cytokines interleukin (IL)-12 and IL-23. Ustekinumab inhibits thebioactivity of human IL-12 and IL-23 by preventing p40 from binding to the IL-12Rβ1 receptorprotein expressed on the surface of immune cells. Ustekinumab cannot bind to IL-12 or IL-23 that isalready bound to IL-12Rβ1 cell surface receptors. Thus, ustekinumab is not likely to contribute tocomplement- or antibody-mediated cytotoxicity of cells with IL-12 and/or IL-23 receptors. IL-12 and

IL-23 are heterodimeric cytokines secreted by activated antigen presenting cells, such as macrophagesand dendritic cells, and both cytokines participate in immune functions; IL-12 stimulates natural killer(NK) cells and drives the differentiation of CD4+ T cells toward the T helper 1 (Th1) phenotype,

IL-23 induces the T helper 17 (Th17) pathway. However, abnormal regulation of IL 12 and IL 23 hasbeen associated with immune mediated diseases, such as psoriasis, psoriatic arthritis, and Crohn’sdisease.

By binding the shared p40 subunit of IL-12 and IL-23, ustekinumab may exert its clinical effects inpsoriasis, psoriatic arthritis, and Crohn’s disease and through interruption of the Th1 and Th17cytokine pathways, which are central to the pathology of these diseases.

In patients with Crohn’s disease, treatment with ustekinumab resulted in a decrease in inflammatorymarkers including C-Reactive Protein (CRP) and fecal calprotectin during the induction phase, whichwere then maintained throughout the maintenance phase. CRP was assessed during the study extensionand the reductions observed during maintenance were generally sustained through week 252.

During the long term extension of Psoriasis Study 2 (PHOENIX 2), adult patients treated withustekinumab for at least 3.5 years mounted similar antibody responses to both pneumococcalpolysaccharide and tetanus vaccines as a non-systemically treated psoriasis control group. Similarproportions of adult patients developed protective levels of anti-pneumococcal and anti-tetanusantibodies and antibody titres were similar among ustekinumab -treated and control patients.

Plaque psoriasis (Adults)

The safety and efficacy of ustekinumab was assessed in 1,996 patients in two randomised,double-blind, placebo-controlled studies in patients with moderate to severe plaque psoriasis and whowere candidates for phototherapy or systemic therapy. In addition, a randomised, blinded assessor,active-controlled study compared ustekinumab and etanercept in patients with moderate to severeplaque psoriasis who had had an inadequate response to, intolerance to, or contraindication tociclosporin, MTX, or PUVA.

Psoriasis Study 1 (PHOENIX 1) evaluated 766 patients. 53% of these patients were eithernon-responsive, intolerant, or had a contraindication to other systemic therapy. Patients randomised toustekinumab received 45 mg or 90 mg doses at Weeks 0 and 4 and followed by the same dose every12 weeks. Patients randomised to receive placebo at Weeks 0 and 4 crossed over to receiveustekinumab (either 45 mg or 90 mg) at Weeks 12 and 16 followed by dosing every 12 weeks. Patientsoriginally randomised to ustekinumab who achieved Psoriasis Area and Severity Index 75 response(PASI improvement of at least 75% relative to baseline) at both Weeks 28 and 40 were re-randomisedto receive ustekinumab every 12 weeks or to placebo (i.e., withdrawal of therapy). Patients who werere-randomised to placebo at week 40 reinitiated ustekinumab at their original dosing regimen whenthey experienced at least a 50% loss of their PASI improvement obtained at week 40. All patients werefollowed for up to 76 weeks following first administration of study treatment.

Psoriasis Study 2 (PHOENIX 2) evaluated 1,230 patients. 61% of these patients were eithernon-responsive, intolerant, or had a contraindication to other systemic therapy. Patients randomised toustekinumab received 45 mg or 90 mg doses at Weeks 0 and 4 followed by an additional dose at16 weeks. Patients randomised to receive placebo at Weeks 0 and 4 crossed over to receiveustekinumab (either 45 mg or 90 mg) at Weeks 12 and 16. All patients were followed for up to52 weeks following first administration of study treatment.

Psoriasis Study 3 (ACCEPT) evaluated 903 patients with moderate to severe psoriasis whoinadequately responded to, were intolerant to, or had a contraindication to other systemic therapy andcompared the efficacy of ustekinumab to etanercept and evaluated the safety of ustekinumab andetanercept. During the 12-week active-controlled portion of the study, patients were randomised toreceive etanercept (50 mg twice a week), ustekinumab 45 mg at Weeks 0 and 4, or ustekinumab 90 mgat Weeks 0 and 4.

Baseline disease characteristics were generally consistent across all treatment groups in Psoriasis

Studies 1 and 2 with a median baseline PASI score from 17 to 18, median baseline Body Surface Area(BSA) ≥ 20, and median Dermatology Life Quality Index (DLQI) range from 10 to 12. Approximatelyone third (Psoriasis Study 1) and one quarter (Psoriasis Study 2) of subjects had Psoriatic Arthritis(PsA). Similar disease severity was also seen in Psoriasis Study 3.

The primary endpoint in these studies was the proportion of patients who achieved PASI 75 responsefrom baseline at week 12 (see Tables 2 and 3).

In Psoriasis Study 1 maintenance of PASI 75 was significantly superior with continuous treatmentcompared with treatment withdrawal (p < 0.001). Similar results were seen with each dose ofustekinumab. At 1 year (week 52), 89% of patients re-randomised to maintenance treatment were

PASI 75 responders compared with 63% of patients re-randomised to placebo (treatment withdrawal)(p < 0.001). At 18 months (week 76), 84% of patients re-randomised to maintenance treatment were

PASI 75 responders compared with 19% of patients re-randomised to placebo (treatment withdrawal).

At 3 years (week 148), 82% of patients re-randomised to maintenance treatment were PASI 75responders. At 5 years (week 244), 80% of patients re-randomised to maintenance treatment were

PASI 75 responders.

In patients re-randomised to placebo, and who reinitiated their original ustekinumab treatment regimenafter loss of ≥ 50% of PASI improvement 85% regained PASI 75 response within 12 weeks afterre-initiating therapy.

In Psoriasis Study 1, at week 2 and week 12, significantly greater improvements from baseline weredemonstrated in the DLQI in each ustekinumab treatment group compared with placebo. Theimprovement was sustained through week 28. Similarly, significant improvements were seen in

Psoriasis Study 2 at week 4 and 12, which were sustained through week 24. In Psoriasis Study 1,improvements in nail psoriasis (Nail Psoriasis Severity Index), in the physical and mental componentsummary scores of the SF-36 and in the Itch Visual Analogue Scale (VAS) were also significant ineach ustekinumab treatment group compared with placebo. In Psoriasis Study 2, the Hospital Anxietyand Depression Scale (HADS) and Work Limitations Questionnaire (WLQ) were also significantlyimproved in each ustekinumab treatment group compared with placebo.

Psoriatic arthritis (PsA) (Adults)

Ustekinumab has been shown to improve signs and symptoms, physical function and health-relatedquality of life, and reduce the rate of progression of peripheral joint damage in adult patients withactive PsA.

The safety and efficacy of ustekinumab was assessed in 927 patients in two randomised, double-blind,placebo-controlled studies in patients with active PsA (≥ 5 swollen joints and ≥ 5 tender joints) despitenon-steroidal anti-inflammatory (NSAID) or disease modifying antirheumatic (DMARD) therapy.

Patients in these studies had a diagnosis of PsA for at least 6 months. Patients with each subtype of

PsA were enrolled, including polyarticular arthritis with no evidence of rheumatoid nodules (39%),spondylitis with peripheral arthritis (28%), asymmetric peripheral arthritis (21%), distalinterphalangeal involvement (12%) and arthritis mutilans (0.5%). Over 70% and 40% of the patients inboth studies had enthesitis and dactylitis at baseline, respectively. Patients were randomised to receivetreatment with ustekinumab 45 mg, 90 mg, or placebo subcutaneously at Weeks 0 and 4 followed byevery 12 weeks (q12w) dosing. Approximately 50% of patients continued on stable doses of MTX(≤ 25 mg/week).

In PsA Study 1 (PSUMMIT I) and PsA Study 2 (PSUMMIT II), 80% and 86% of the patients,respectively, had been previously treated with DMARDs. In Study 1 previous treatment withanti-tumour necrosis factor (TNF)α agent was not allowed. In Study 2, the majority of patients (58%,n = 180) had been previously treated with one or more anti-TNFα agent(s), of whom over 70% haddiscontinued their anti-TNFα treatment for lack of efficacy or intolerance at any time.

Signs and symptoms

Treatment with ustekinumab resulted in significant improvements in the measures of disease activitycompared to placebo at week 24. The primary endpoint was the percentage of patients who achieved

American College of Rheumatology (ACR) 20 response at week 24. The key efficacy results areshown in Table 4 below.

ACR 20, 50 and 70 responses continued to improve or were maintained through week 52 (PsA Study 1and 2) and week 100 (PsA Study 1). In PsA Study 1, ACR 20 responses at week 100 were achieved by57% and 64%, for 45 mg and 90 mg, respectively. In PsA Study 2, ACR 20 responses at week 52 wereachieved by 47% and 48%, for 45 mg and 90 mg, respectively.

The proportion of patients achieving a modified PsA response criteria (PsARC) response was alsosignificantly greater in the ustekinumab groups compared to placebo at week 24. PsARC responseswere maintained through weeks 52 and 100. A higher proportion of patients treated with ustekinumabwho had spondylitis with peripheral arthritis as their primary presentation, demonstrated 50 and70 percent improvement in Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) scorescompared with placebo at week 24.

Responses observed in the ustekinumab treated groups were similar in patients receiving and notreceiving concomitant MTX, and were maintained through weeks 52 and 100. Patients previouslytreated with anti-TNFα agents who received ustekinumab achieved a greater response at week 24 thanpatients receiving placebo (ACR 20 response at week 24 for 45 mg and 90 mg was 37% and 34%,respectively, compared with placebo 15%; p < 0.05), and responses were maintained through week 52.

For patients with enthesitis and/or dactylitis at baseline, in PsA Study 1 significant improvement inenthesitis and dactylitis score was observed in the ustekinumab groups compared with placebo atweek 24. In PsA Study 2 significant improvement in enthesitis score and numerical improvement (notstatistically significant) in dactylitis score was observed in the ustekinumab 90 mg group comparedwith placebo at week 24. Improvements in enthesitis score and dactylitis score were maintainedthrough weeks 52 and 100.

Radiographic Response

Structural damage in both hands and feet was expressed as change in total van der Heijde-Sharp score(vdH-S score), modified for PsA by addition of hand distal interphalangeal joints, compared tobaseline. A pre-specified integrated analysis combining data from 927 subjects in both PsA Study 1and 2 was performed. Ustekinumab demonstrated a statistically significant decrease in the rate ofprogression of structural damage compared to placebo, as measured by change from baseline toweek 24 in the total modified vdH-S score (mean ± SD score was 0.97 ± 3.85 in the placebo groupcompared with 0.40 ± 2.11 and 0.39 ± 2.40 in the ustekinumab 45 mg (p < 0.05) and 90 mg(p < 0.001) groups, respectively). This effect was driven by PsA Study 1. The effect is considereddemonstrated irrespective of concomitant MTX use, and was maintained through Weeks 52 (integratedanalysis) and 100 (PsA Study 1).

Ustekinumab-treated patients showed significant improvement in physical function as assessed by the

Disability Index of the Health Assessment Questionnaire (HAQ-DI) at week 24. The proportion ofpatients achieving a clinically meaningful ≥ 0.3 improvement in HAQ-DI score from baseline was alsosignificantly greater in the ustekinumab groups when compared with placebo. Improvement in

HAQ-DI score from baseline was maintained through Weeks 52 and 100.

There was significant improvement in DLQI scores in the ustekinumab groups as compared withplacebo at week 24, which was maintained through weeks 52 and 100. In PsA Study 2 there was asignificant improvement in Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F)scores in the ustekinumab groups when compared with placebo at week 24. The proportion of patientsachieving a clinically significant improvement in fatigue (4 points in FACIT-F) was also significantlygreater in the ustekinumab groups compared with placebo. Improvements in FACIT scores weremaintained through week 52.

The European Medicines Agency has deferred the obligation to submit the results of studies withustekinumab in one or more subsets of the paediatric population with juvenile idiopathic arthritis. Thepre-filled pen has not been studied in the paediatric psoriasis population and is not recommended foruse by paediatric patients.

Crohn’s Disease

The safety and efficacy of ustekinumab was assessed in three randomised, double-blind, placebo-controlled, multicentre studies in adult patients with moderately to severely active Crohn’s disease(Crohn’s Disease Activity Index [CDAI] score of ≥ 220 and ≤ 450). The clinical development programconsisted of two 8-week intravenous induction studies (UNITI-1 and UNITI-2) followed by a 44 weeksubcutaneous randomised withdrawal maintenance study (IM-UNITI) representing 52 weeks oftherapy.

The induction studies included 1,409 (UNITI-1, n = 769; UNITI-2 n = 640) patients. The primaryendpoint for both induction studies was the proportion of subjects in clinical response (defined as areduction in CDAI score of ≥ 100 points) at week 6. Efficacy data were collected and analysedthrough week 8 for both studies. Concomitant doses of oral corticosteroids, immunomodulators,aminosalicylates and antibiotics were permitted and 75% of patients continued to receive at least oneof these medications. In both studies, patients were randomised to receive a single intravenousadministration of either the recommended tiered dose of approximately 6 mg/kg (see section 4.2 of theustekinumab 130 mg Concentrate for solution for infusion SmPC), a fixed dose of 130 mgustekinumab, or placebo at week 0.

Patients in UNITI-1 had failed or were intolerant to prior anti-TNFα therapy. Approximately 48% ofthe patients had failed 1 prior anti-TNFα therapy and 52% had failed 2 or 3 prior anti-TNFα therapies.

In this study, 29.1% of the patients had an inadequate initial response (primary non-responders),69.4% responded but lost response (secondary non-responders), and 36.4% were intolerant to anti-

TNFα therapies.

Patients in UNITI-2 had failed at least one conventional therapy, including corticosteroids orimmunomodulators, and were either anti-TNF-α naïve (68.6%) or had previously received but notfailed anti-TNFα therapy (31.4%).

In both UNITI-1 and UNITI-2, a significantly greater proportion of patients were in clinical responseand remission in the ustekinumab treated group compared to placebo (Table 5). Clinical response andremission were significant as early as week 3 in ustekinumab treated patients and continued toimprove through week 8. In these induction studies, efficacy was higher and better sustained in thetiered dose group compared to the 130 mg dose group, and tiered dosing is therefore the recommendedintravenous induction dose.

The maintenance study (IM-UNITI), evaluated 388 patients who achieved 100 point clinical responseat week 8 of induction with ustekinumab in studies UNITI-1 and UNITI-2. Patients were randomisedto receive a subcutaneous maintenance regimen of either 90 mg ustekinumab every 8 weeks, 90 mgustekinumab every 12 weeks or placebo for 44 weeks (for recommended maintenance posology, seesection 4.2).

Significantly higher proportions of patients maintained clinical remission and response in theustekinumab treated groups compared to the placebo group at week 44 (see Table 6).

In IM-UNITI, 29 of 129 patients did not maintain response to ustekinumab when treated every12 weeks and were allowed to dose adjust to receive ustekinumab every 8 weeks. Loss of responsewas defined as a CDAI score ≥ 220 points and a ≥ 100 point increase from the CDAI score at baseline.

In these patients, clinical remission was achieved in 41.4% of patients 16 weeks after dose adjustment.

Patients who were not in clinical response to ustekinumab induction at week 8 of the UNITI-1 and

UNITI-2 induction studies (476 patients) entered into the non-randomised portion of the maintenancestudy (IM-UNITI) and received a 90 mg subcutaneous injection of ustekinumab at that time.

Eight weeks later, 50.5% of the patients achieved clinical response and continued to receivemaintenance dosing every 8 weeks; among these patients with continued maintenance dosing, amajority maintained response (68.1%) and achieved remission (50.2%) at week 44, at proportions thatwere similar to the patients who initially responded to ustekinumab induction.

Of 131 patients who responded to ustekinumab induction, and were randomised to the placebo groupat the start of the maintenance study, 51 subsequently lost response and received 90 mg ustekinumabsubcutaneously every 8 weeks. The majority of patients who lost response and resumed ustekinumabdid so within 24 weeks of the induction infusion. Of these 51 patients, 70.6% achieved clinicalresponse and 39.2% percent achieved clinical remission 16 weeks after receiving the firstsubcutaneous dose of ustekinumab.

In IM-UNITI, patients who completed the study through week 44 were eligible to continue treatmentin a study extension. Among the 567 patients who entered on and were treated with ustekinumab in thestudy extension, clinical remission and response were generally maintained through week 252 for bothpatients who failed TNF-therapies and those who failed conventional therapies.

No new safety concerns were identified in this study extension with up to 5 years of treatment inpatients with Crohn’s Disease.

Endoscopy

Endoscopic appearance of the mucosa was evaluated in 252 patients with eligible baseline endoscopicdisease activity in a substudy. The primary endpoint was change from baseline in Simplified

Endoscopic Disease Severity Score for Crohn’s Disease (SES-CD), a composite score across 5 ileo-colonic segments of presence/size of ulcers, proportion of mucosal surface covered by ulcers,proportion of mucosal surface affected by any other lesions and presence/type of narrowing/strictures.

At week 8, after a single intravenous induction dose, the change in SES-CD score was greater in theustekinumab group (n = 155, mean change = -2.8) than in the placebo group (n = 97, meanchange = -0.7, p = 0.012).

Fistula Response

In a subgroup of patients with draining fistulas at baseline (8.8%; n = 26), 12/15 (80%) ofustekinumab-treated patients achieved a fistula response over 44 weeks (defined as ≥ 50% reductionfrom baseline of the induction study in the number of draining fistulas) compared to 5/11 (45.5%)exposed to placebo.

Health-related quality of life was assessed by Inflammatory Bowel Disease Questionnaire (IBDQ) and

SF-36 questionnaires. At week 8, patients receiving ustekinumab showed statistically significantlygreater and clinically meaningful improvements on IBDQ total score and SF-36 Mental Component

Summary Score in both UNITI-1 and UNITI-2, and SF-36 Physical Component Summary Score in

UNITI-2, when compared to placebo. These improvements were generally better maintained inustekinumab-treated patients in the IM-UNITI study through week 44 when compared to placebo.

Improvement in health-related quality of life was generally maintained during the extension throughweek 252.

Antibodies to ustekinumab may develop during ustekinumab treatment and most are neutralising. Theformation of anti-ustekinumab antibodies is associated with both increased clearance and reducedefficacy of ustekinumab, except in patients with Crohn’s disease where no reduced efficacy wasobserved. There is no apparent correlation between the presence of anti-ustekinumab antibodies andthe occurrence of injection site reactions.

The European Medicines Agency has deferred the obligation to submit the results of studies withustekinumab in one or more subsets of the paediatric population in Crohn’s Disease. The pre-filled penhas not been studied in the paediatric population and is not recommended for use by paediatricpatients.

The median time to reach the maximum serum concentration (tmax) was 8.5 days after a single 90 mgsubcutaneous administration in healthy subjects. The median tmax values of ustekinumab following asingle subcutaneous administration of either 45 mg or 90 mg in patients with psoriasis werecomparable to those observed in healthy subjects.

The absolute bioavailability of ustekinumab following a single subcutaneous administration wasestimated to be 57.2% in patients with psoriasis.

Median volume of distribution during the terminal phase (Vz) following a single intravenousadministration to patients with psoriasis ranged from 57 to 83 mL/kg.

The exact metabolic pathway for ustekinumab is unknown.

Median systemic clearance (CL) following a single intravenous administration to patients withpsoriasis ranged from 1.99 to 2.34 mL/day/kg. Median half-life (t1/2) of ustekinumab wasapproximately 3 weeks in patients with psoriasis, psoriatic arthritis, or Crohn’s disease, ranging from15 to 32 days across all psoriasis and psoriatic arthritis studies. In a population pharmacokineticanalysis, the apparent clearance (CL/F) and apparent volume of distribution (V/F) were 0.465 l/dayand 15.7 l, respectively, in patients with psoriasis. The CL/F of ustekinumab was not impacted bygender. Population pharmacokinetic analysis showed that there was a trend towards a higher clearanceof ustekinumab in patients who tested positive for antibodies to ustekinumab.

Dose linearity

The systemic exposure of ustekinumab (Cmax and AUC) increased in an approximatelydose-proportional manner after a single intravenous administration at doses ranging from 0.09 mg/kgto 4.5 mg/kg or following a single subcutaneous administration at doses ranging from approximately24 mg to 240 mg in patients with psoriasis.

Single dose versus multiple doses

Serum concentration-time profiles of ustekinumab were generally predictable after single or multiplesubcutaneous dose administrations. In patients with psoriasis, steady-state serum concentrations ofustekinumab were achieved by week 28 after initial subcutaneous doses at Weeks 0 and 4 followed bydoses every 12 weeks. The median steady-state trough concentration ranged from 0.21 μg/mL to0.26 μg/mL (45 mg) and from 0.47 μg/mL to 0.49 μg/mL (90 mg). There was no apparentaccumulation in serum ustekinumab concentration over time when given subcutaneously every12 weeks.

In patients with Crohn’s disease, following an intravenous dose of ~6 mg/kg, starting at week 8,subcutaneous maintenance dosing of 90 mg ustekinumab was administered every 8 or 12 weeks.

Steady state ustekinumab concentration was achieved by the start of the second maintenance dose. Inpatients with Crohn’s disease, median steady-state trough concentrations ranged from 1.97 μg/mL to2.24 μg/mL and from 0.61 μg/mL to 0.76 μg/mL for 90 mg ustekinumab every 8 weeks or every12 weeks respectively. The steady-state trough ustekinumab levels resulting from 90 mg ustekinumabevery 8 weeks were associated with higher clinical remission rates as compared to the steady-statetrough levels following 90 mg every 12 weeks.

Impact of weight on pharmacokinetics

In a population pharmacokinetic analysis using data from patients with psoriasis, body weight wasfound to be the most significant covariate affecting the clearance of ustekinumab. The median CL/F inpatients with weight > 100 kg was approximately 55% higher compared to patients with weight≤ 100 kg. The median V/F in patients with weight > 100 kg was approximately 37% higher ascompared to patients with weight ≤ 100 kg. The median trough serum concentrations of ustekinumabin patients with higher weight (> 100 kg) in the 90 mg group were comparable to those in patients withlower weight (≤ 100 kg) in the 45 mg group. Similar results were obtained from a confirmatorypopulation pharmacokinetic analysis using data from patients with psoriatic arthritis.

Dosing frequency adjustment

In patients with Crohn’s disease, based on observed data and population PK analyses, randomisedsubjects who lost response to treatment had lower serum ustekinumab concentrations over timecompared with subjects who did not lose response. In Crohn’s disease, dose adjustment from 90 mgevery 12 weeks to 90 mg every 8 weeks was associated with an increase in trough serum ustekinumabconcentrations and an accompanying increase in efficacy.

No pharmacokinetic data are available in patients with impaired renal or hepatic function.

No specific studies have been conducted in elderly patients.

The pharmacokinetics of ustekinumab were generally comparable between Asian and non-Asianpatients with psoriasis.

In patients with Crohn’s disease, variability in ustekinumab clearance was affected by body weight,serum albumin level, sex, and antibody to ustekinumab status while body weight was the maincovariate affecting the volume of distribution. Additionally in Crohn’s disease, clearance was affectedby C-reactive protein, TNF antagonist failure status and race (Asian versus non-Asian). The impact ofthese covariates was within ± 20% of the typical or reference value of the respective PK parameter,thus dose adjustment is not warranted for these covariates. Concomitant use of immunomodulators didnot have a significant impact on ustekinumab disposition.

In the population pharmacokinetic analysis, there were no indications of an effect of tobacco oralcohol on the pharmacokinetics of ustekinumab.

The bioavailability of ustekinumab following administration by syringe or pre-filled pen wascomparable.

The pre-filled pen has not been studied in the paediatric population and is not recommended for use bypaediatric patients.

Regulation of CYP450 enzymes

The effects of IL-12 or IL-23 on the regulation of CYP450 enzymes were evaluated in an in vitrostudy using human hepatocytes, which showed that IL-12 and/or IL-23 at levels of 10 ng/mL did notalter human CYP450 enzyme activities (CYP1A2, 2B6, 2C9, 2C19, 2D6, or 3A4; see section 4.5).

Non-clinical data reveal no special hazard (e.g. organ toxicity) for humans based on studies ofrepeated-dose toxicity and developmental and reproductive toxicity, including safety pharmacologyevaluations. In developmental and reproductive toxicity studies in cynomolgus monkeys, neitheradverse effects on male fertility indices nor birth defects or developmental toxicity were observed. Noadverse effects on female fertility indices were observed using an analogous antibody to IL-12/23 inmice.

Dose levels in animal studies were up to approximately 45-fold higher than the highest equivalent doseintended to be administered to psoriasis patients and resulted in peak serum concentrations in monkeysthat were more than 100-fold higher than observed in humans.

Carcinogenicity studies were not performed with ustekinumab due to the lack of appropriate modelsfor an antibody with no cross-reactivity to rodent IL-12/23 p40.
