Exon 20 insertion mutations, after failure of platinum-based therapy.
4.2 Posology and method of administration
Treatment with Rybrevant should be initiated and supervised by a physician experienced in the use ofanticancer medicinal products.
Rybrevant should be administered by a healthcare professional with access to appropriate medicalsupport to manage infusion-related reactions (IRRs) if they occur.
Before initiation of Rybrevant therapy, EGFR mutation status in tumour tissue or plasma specimensmust be established using a validated test method. If no mutation is detected in a plasma specimen,tumour tissue should be tested if available in sufficient amount and quality due to the potential forfalse negative results using a plasma-test. Testing may be performed at any time from initial diagnosisuntil the initiation of therapy; testing does not need to be repeated once EGFR mutation status hasbeen established (see section 5.1).
PosologyPremedications should be administered to reduce the risk of IRRs with Rybrevant (see below “Dosemodifications” and “Recommended concomitant medicinal products”).
Every 3 weeks
The recommended dosages of Rybrevant, when used in combination with carboplatin and pemetrexed,is provided in Table 1 (see below “Infusion rates” and Table 5).

Infusion-related reactionsInfusion should be interrupted at the first sign of IRRs. Additional supportive medicinal products (e.g.,additional glucocorticoids, antihistamine, antipyretics and antiemetics) should be administered asclinically indicated (see section 4.4).
- Grade 1-3 (mild-severe): Upon recovery from symptoms, resume infusion at 50% of theprevious rate. If there are no additional symptoms, the rate may be increased per therecommended infusion rate (see Tables 5 and 6). Concomitant medicinal products should beadministered at the next dose (including dexamethasone (20 mg) or equivalent (see Table 4).
- Recurrent Grade 3 or Grade 4 (life-threatening): Permanently discontinue Rybrevant.
Venous thromboembolic (VTE) events with concomitant use with lazertinib
At the initiation of treatment, prophylactic anticoagulants should be administered to prevent VTEevents in patients receiving Rybrevant in combination with lazertinib. Consistent with clinicalguidelines, patients should receive prophylactic dosing of either a direct acting oral anticoagulant(DOAC) or a low-molecular weight heparin (LMWH). Use of Vitamin K antagonists is notrecommended.
For VTE events associated with clinical instability (e.g., respiratory failure or cardiac dysfunction),both drugs should be withheld until the patient is clinically stable. Thereafter, both medicinal productscan be resumed at the same dose. In the event of recurrence despite appropriate anticoagulation,discontinue Rybrevant. Treatment can continue with lazertinib at the same dose.
Skin and nail reactions
Patients should be instructed to limit sun exposure during and for 2 months after Rybrevant therapy.
Alcohol-free emollient cream is recommended for dry areas. For further information aboutprophylaxis for skin and nail reactions, see section 4.4. If the patient develops a Grade 1-2 skin or nailreaction, supportive care should be initiated; if there is no improvement after 2 weeks, dose reductionshould be considered for persistent Grade 2 rash (see Table 3). If the patient develops a Grade 3 skinor nail reaction, supportive care should be initiated, and interruption of Rybrevant should beconsidered until the adverse reaction improves. Upon recovery of the skin or nail reaction to≤ Grade 2, Rybrevant should be resumed at a reduced dose. If the patient develops Grade 4 skinreactions, permanently discontinue Rybrevant (see section 4.4).
Interstitial lung diseaseRybrevant should be withheld if interstitial lung disease (ILD) or ILD-like adverse reactions(pneumonitis) is suspected. If the patient is confirmed to have ILD or ILD-like adverse reactions (e.g.,pneumonitis), permanently discontinue Rybrevant (see section 4.4).
Recommended concomitant medicinal products
Prior to infusion (Week 1, Days 1 and 2), antihistamines, antipyretics, and glucocorticoids should beadministered to reduce the risk of IRRs (see Table 4). For subsequent doses, antihistamines andantipyretics are required to be administered. Glucocorticoids should also be re-initiated afterprolonged dose interruptions. Antiemetics should be administered as needed.

Special populationsPaediatric populationThere is no relevant use of amivantamab in the paediatric population in the treatment of non-small celllung cancer.
ElderlyNo dose adjustments are necessary (see section 4.8, section 5.1, and section 5.2).
Renal impairmentNo formal studies of amivantamab in patients with renal impairment have been conducted. Based onpopulation pharmacokinetic (PK) analyses, no dose adjustment is necessary for patients with mild ormoderate renal impairment. Caution is required in patients with severe renal impairment asamivantamab has not been studied in this patient population (see section 5.2). If treatment is started,patients should be monitored for adverse reactions with dose modifications per the recommendationsabove.
Hepatic impairmentNo formal studies of amivantamab in patients with hepatic impairment have been conducted. Based onpopulation PK analyses, no dose adjustment is necessary for patients with mild hepatic impairment.
Caution is required in patients with moderate or severe hepatic impairment as amivantamab has notbeen studied in this patient population (see section 5.2). If treatment is started, patients should bemonitored for adverse reactions with dose modifications per the recommendations above.
Method of administrationRybrevant is for intravenous use. It is administered as an intravenous infusion following dilution withsterile 5% glucose solution or sodium chloride 9 mg/mL (0.9%) solution for injection. Rybrevant mustbe administered with in-line filtration.
For instructions on dilution of the medicinal product before administration, see section 6.6.
Infusion rates
Following dilution, the infusion should be administered intravenously at the infusion rates presented in
Table 5 or 6 below. Due to the frequency of IRRs at the first dose, amivantamab should be infused viaa peripheral vein at Week 1 and Week 2; infusion via a central line may be administered forsubsequent weeks when the risk of IRR is lower (see section 6.6). It is recommended for the first doseto be prepared as close to administration as possible to maximise the likelihood of completing theinfusion in the event of an IRR.

4.3 Contraindications
Hypersensitivity to the active substance(s) or to any of the excipients listed in section 6.1.
4.4 Special warnings and precautions for use
TraceabilityIn order to improve the traceability of biological medicinal products, the name and the batch numberof the administered product should be clearly recorded.
Infusion-related reactionsInfusion-related reactions commonly occurred in patients treated with amivantamab (see section 4.8).
Prior to initial infusion (Week 1), antihistamines, antipyretics, and glucocorticoids should beadministered to reduce the risk of IRRs. For subsequent doses, antihistamines and antipyretics shouldbe administered. The initial infusion should be administered in split doses on Week 1, Day 1 and 2.
Patients should be treated in a setting with appropriate medical support to treat IRRs. Infusions shouldbe interrupted at the first sign of IRRs of any severity and post-infusion medicinal products should beadministered as clinically indicated. Upon resolution of symptoms, the infusion should be resumed at50% of the previous rate. For recurrent Grade 3 or Grade 4 IRRs, Rybrevant should be permanentlydiscontinued (see section 4.2).
Interstitial lung diseaseInterstitial lung disease (ILD) or ILD-like adverse reactions (e.g., pneumonitis) have been reported inpatients treated with amivantamab, including fatal events (see section 4.8). Patients should bemonitored for symptoms indicative of ILD/pneumonitis (e.g., dyspnoea, cough, fever). If symptomsdevelop, treatment with Rybrevant should be interrupted pending investigation of these symptoms.
Suspected ILD or ILD-like adverse reactions should be evaluated and appropriate treatment should beinitiated as necessary. Rybrevant should be permanently discontinued in patients with confirmed ILDor ILD-like adverse reactions (see section 4.2).
Venous thromboembolic (VTE) events with concomitant use with lazertinib
In patients receiving Rybrevant in combination with lazertinib, VTE events, including deep veinthrombosis (DVT) and pulmonary embolism (PE), including fatal events, were reported (seesection 4.8). Consistent with clinical guidelines, patients should receive prophylactic dosing of either adirect acting oral anticoagulant (DOAC) or a low-molecular weight heparin (LMWH). Use of
Vitamin K antagonists is not recommended.
Signs and symptoms of VTE events should be monitored. Patients with VTE events should be treatedwith anticoagulation as clinically indicated. For VTE events associated with clinical instabilitytreatment should be withheld until the patient is clinically stable. Thereafter, both drugs can beresumed at the same dose.
In the event of recurrence despite appropriate anticoagulation, Rybrevant should be discontinued.
Treatment can continue with lazertinib at the same dose (see section 4.2).
Skin and nail reactions
Rash (including dermatitis acneiform), pruritus and dry skin occurred in patients treated withamivantamab (see section 4.8). Patients should be instructed to limit sun exposure during and for2 months after Rybrevant therapy. Protective clothing and use of broad-spectrum UVA/UVBsunscreen are advisable. Alcohol-free emollient cream is recommended for dry areas. A prophylacticapproach to rash prevention should be considered. This includes prophylactic therapy with an oralantibiotic (e.g., doxycycline or minocycline, 100 mg twice daily) starting on Day 1 for the first12 weeks of treatment and after completion of oral antibiotic therapy, topical antibiotic lotion to thescalp (e.g., clindamycin 1%) for the next 9 months of treatment. Non-comedogenic skin moisturiser onthe face and whole body (except scalp) and chlorhexidine solution to wash hands and feet should beconsidered beginning on Day 1 and continued for the first 12 months of treatment.
Prescriptions for topical and/or oral antibiotics and topical corticosteroids are recommended to beavailable at the time of initial dosing to minimise any delay in reactive management should rashdevelop despite prophylactic treatment. If skin reactions develop, topical corticosteroids and topicaland/or oral antibiotics should be administered. For Grade 3 or poorly-tolerated Grade 2 events,systemic antibiotics and oral steroids should also be administered. Patients presenting with severe rashthat has an atypical appearance or distribution or lack improvement within 2 weeks should be referredpromptly to a dermatologist. Rybrevant should be dose reduced, interrupted, or permanentlydiscontinued based on severity (see section 4.2).
Toxic epidermal necrolysis (TEN) has been reported. Treatment with this medicinal product should bediscontinued if TEN is confirmed.
Eye disordersEye disorders, including keratitis, occurred in patients treated with amivantamab (see section 4.8).
Patients presenting with worsening eye symptoms should promptly be referred to an ophthalmologistand should discontinue use of contact lenses until symptoms are evaluated. For dose modifications for
Grade 3 or 4 eye disorders, see section 4.2.
Sodium contentThis medicinal product contains less than 1 mmol (23 mg) sodium per dose, that is to say essentially“sodium-free”. This medicinal product may be diluted in sodium chloride 9 mg/mL (0.9%) solutionfor infusion. This should be taken into consideration for patients on a controlled sodium diet (seesection 6.6).
Polysorbate content
This medicinal product contains 0.6 mg of polysorbate 80 in each mL, which is equivalent to 4.2 mgper 7 mL vial. Polysorbates may cause hypersensitivity reactions.
4.5 Interaction with other medicinal products and other forms of interaction
No drug interaction studies have been performed. As an IgG1 monoclonal antibody, renal excretionand hepatic enzyme-mediated metabolism of intact amivantamab are unlikely to be major eliminationroutes. As such, variations in drug-metabolising enzymes are not expected to affect the elimination ofamivantamab. Due to the high affinity to a unique epitope on EGFR and MET, amivantamab is notanticipated to alter drug-metabolising enzymes.
Vaccines
No clinical data are available on the efficacy and safety of vaccinations in patients takingamivantamab. Avoid the use of live or live-attenuated vaccines while patients are taking amivantamab.
4.6 Fertility, pregnancy and lactation
Women of child-bearing potential/Contraception
Women of child-bearing potential should use effective contraception during and for 3 months aftercessation of amivantamab treatment.
PregnancyThere are no human data to assess the risk of amivantamab use during pregnancy. No animalreproductive studies were conducted to inform a drug-associated risk. Administration of EGFR and
MET inhibitor molecules in pregnant animals resulted in an increased incidence of impairment ofembryo-foetal development, embryo lethality, and abortion. Therefore, based on its mechanism ofaction and findings in animal models, amivantamab could cause foetal harm when administered to apregnant woman. Amivantamab should not be given during pregnancy unless the benefit of treatmentof the woman is considered to outweigh potential risks to the foetus. If the patient becomes pregnantwhile taking this medicinal product the patient should be informed of the potential risk to the foetus(see section 5.3).
Breast-feedingIt is unknown whether amivantamab is excreted in human milk. Human IgGs are known to be excretedin breast milk during the first few days after birth, which is decreasing to low concentrations soonafterwards. A risk to the breast-fed child cannot be excluded during this short period just after birth,although IgGs are likely to be degraded in the gastrointestinal tract of the breast-fed child and notabsorbed. A decision must be made whether to discontinue breast-feeding or to discontinue/abstainfrom amivantamab therapy taking into account the benefit of breast-feeding for the child and thebenefit of therapy for the woman.
FertilityThere are no data on the effect of amivantamab on human fertility. Effects on male and female fertilityhave not been evaluated in animal studies.
4.7 Effects on ability to drive and use machines
Rybrevant may have moderate influence on the ability to drive and use machines. Please seesection 4.8 (e.g., dizziness, fatigue, visual impairment). If patients experience treatment-relatedsymptoms, including vision-related adverse reactions, affecting their ability to concentrate and react, itis recommended that they do not drive or use machines until the effect subsides.

Description of selected adverse reactionsInfusion-related reactionsIn patients treated with amivantamab monotherapy, infusion-related reactions occurred in 67% ofpatients. Ninety-eight percent of IRRs were Grade 1-2. Ninety-nine percent of IRRs occurred at thefirst infusion with a median time to onset of 60 minutes, and the majority occurring within 2 hours ofinfusion start. The most frequent signs and symptoms include chills, dyspnoea, nausea, flushing, chestdiscomfort, and vomiting (see section 4.4).
In patients treated with amivantamab in combination with carboplatin and pemetrexed,infusion-related reactions occurred in 50% of patients. Greater than 94% of IRRs were Grade 1-2. Amajority of IRRs occurred at the first infusion with a median time to onset of 60 minutes (range0-7 hours), and the majority occurring within 2 hours of infusion start. Occasionally an IRR can occurat re-initiation of amivantamab after prolonged dose interruptions of more than 6 weeks.
In patients treated with amivantamab in combination with lazertinib, infusion-related reactionsoccurred in 63% of patients. Ninety-four percent of IRRs were Grade 1-2. A majority of IRRsoccurred at the first infusion with a median time to onset of 1 hour, and the majority occurring within2 hours of infusion start. The most frequent signs and symptoms include chills, dyspnoea, nausea,flushing, chest discomfort, and vomiting (see section 4.4)
Occasionally an IRR can occur at re-initiation of amivantamab after prolonged dose interruptions ofmore than 6 weeks.
Interstitial lung diseaseInterstitial lung disease or ILD-like adverse reactions have been reported with the use of amivantamabas well as with other EGFR inhibitors. Interstitial lung disease or pneumonitis was reported in 2.6% ofpatients treated with amivantamab monotherapy, 2.3 % of patients treated with amivantamab incombination with carboplatin and pemetrexed and 3.1% of patients treated with amivantamab incombination with lazertinib, including 1 (0.2%) fatal case. Patients with a medical history of ILD,drug-induced ILD, radiation pneumonitis that required steroid treatment, or any evidence of clinicallyactive ILD were excluded from the clinical study (see section 4.4).
Venous thromboembolic (VTE) events with concomitant use with lazertinib
When Rybrevant is used in combination with lazertinib, VTE events, including deep venousthrombosis (DVT) and pulmonary embolism (PE), were reported in 37% of the 421 patients receiving
Rybrevant in combination with lazertinib. Most cases were Grade 1 or 2, with Grade 3-4 eventsoccurring in 11% of patients receiving Rybrevant in combination with lazertinib and deaths occurringin 0.5% of patients receiving Rybrevant in combination with lazertinib. For information onprophylactic anticoagulants and management of VTE events, see sections 4.2 and 4.4.
In patients receiving Rybrevant in combination with lazertinib, the median time to first onset of a VTEevent was 84 days. VTE events led to Rybrevant treatment discontinuation in 2.9% of patients.

Most events were
Grade 1 or 2, with Grade 3 nail toxicity occurring in 11% of patients (see section 4.4).
Eye disordersEye disorders, including keratitis (0.5%), occurred in 9% of patients treated with amivantamab alone.
Other reported adverse reactions included growth of eyelashes, visual impairment, and other eyedisorders. All events were Grade 1-2.
Eye disorders, including keratitis (0.3%), occurred in 11% of patients treated with amivantamab incombination with carboplatin and pemetrexed. Other reported adverse reactions included growth ofeyelashes, visual impairment, uveitis, and other eye disorders. All events were Grade 1-2 (seesection 4.4).
Eye disorders, including keratitis (2.6%) occurred in patients treated with amivantamab incombination with lazertinib. Other reported adverse reactions included growth of eyelashes, visualimpairment, and other eye disorders. Most events were Grade 1-2 (see section 4.4).
Special populationsElderlyThere are limited clinical data with amivantamab in patients 75 years of age or over (see section 5.1).
No overall differences in safety were observed between patients ≥ 65 years of age and patients< 65 years of age.
ImmunogenicityAs with all therapeutic proteins, there is the potential for immunogenicity. In clinical studies ofpatients with locally advanced or metastatic NSCLC treated with amivantamab, 4 of the 1862 (0.2%)participants who were treated with Rybrevant and evaluable for the presence of anti-drug antibodies(ADA), tested positive for treatment-emergent anti-amivantamab antibodies. There was no evidence ofan altered pharmacokinetic, efficacy, or safety profile due to anti-amivantamab antibodies.
Reporting of suspected adverse reactionsReporting 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.
4.9 Overdose
No maximum tolerated dose has been determined in a clinical study in which patients received up to2100 mg administered intravenously. There is no known specific antidote for amivantamab overdose.
In the event of an overdose, treatment with Rybrevant should be stopped, the patient should bemonitored for any signs or symptoms of adverse events and appropriate general supportive measuresshould be instituted immediately until clinical toxicity has diminished or resolved.
5. PHARMACOLOGICAL PROPERTIES
5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Monoclonal antibodies and antibody drug conjugates, ATC code:
L01FX18.
Mechanism of actionAmivantamab is a low-fucose, fully-human IgG1-based EGFR-MET bispecific antibody with immunecell-directing activity that targets tumours with activating EGFR mutations such as Exon 19 deletions,
Exon 21 L858R substitution, and Exon 20 insertion mutations. Amivantamab binds to the extracellulardomains of EGFR and MET.
Amivantamab disrupts EGFR and MET signalling functions through blocking ligand binding andenhancing degradation of EGFR and MET, thereby preventing tumour growth and progression. Thepresence of EGFR and MET on the surface of tumour cells also allows for targeting of these cells fordestruction by immune effector cells, such as natural killer cells and macrophages, throughantibody-dependent cellular cytotoxicity (ADCC) and trogocytosis mechanisms, respectively.
Pharmacodynamic effectsAlbumin
Amivantamab decreased serum albumin concentration, a pharmacodynamic effect of MET inhibition,typically during the first 8 weeks (see section 4.8); thereafter, albumin concentration stabilised for theremainder of amivantamab treatment.
Clinical efficacy and safetyPreviously-untreated NSCLC with EGFR Exon 19 deletions or Exon 21 L858R substitution mutations(MARIPOSA)
NSC3003 (MARIPOSA) is a randomised, open-label, active-controlled, multicenter phase 3 studyassessing the efficacy and safety of Rybrevant in combination with lazertinib as compared toosimertinib monotherapy as first-line treatment in patients with EGFR-mutated locally advanced ormetastatic NSCLC not amenable to curative therapy. Patient samples were required to have one of thetwo common EGFR mutations (Exon 19 deletion or Exon 21 L858R substitution mutation), asidentified by local testing. Tumour tissue (94%) and/or plasma (6%) samples for all patients weretested locally to determine EGFR Exon 19 deletion and/or Exon 21 L858R substitution mutation statususing polymerase chain reaction (PCR) in 65% and next generation sequencing (NGS) in 35% ofpatients.
A total of 1074 patients were randomised (2:2:1) to receive Rybrevant in combination with lazertinib,osimertinib monotherapy, or lazertinib monotherapy until disease progression or unacceptable toxicity.
Rybrevant was administered intravenously at 1050 mg (for patients < 80 kg) or 1400 mg (for patients≥ 80 kg) once weekly for 4 weeks, then every 2 weeks thereafter starting at week 5. Lazertinib wasadministered at 240 mg orally once daily. Osimertinib was administered at a dose of 80 mg orally oncedaily. Randomisation was stratified by EGFR mutation type (Exon 19 deletion or Exon 21 L858R),race (Asian or non-Asian), and history of brain metastasis (yes or no).
Baseline demographics and disease characteristics were balanced across the treatment arms. Themedian age was 63 (range: 25-88) years with 45% of patients ≥ 65 years; 62% were female; and 59%were Asian, and 38% were White. Baseline Eastern Cooperative Oncology Group (ECOG)performance status was 0 (34%) or 1 (66%); 69% never smoked; 41% had prior brain metastases; and90% had Stage IV cancer at initial diagnosis. With regard to EGFR mutation status, 60% were
Exon 19 deletions and 40% were Exon 21 L858R substitution mutations.
Rybrevant in combination with lazertinib demonstrated a statistically significant improvement inprogression-free survival (PFS) by BICR assessment.
With a median follow up of approximately 31 months, the updated OS HR was 0.77; (95% CI: 0.61,0.96; p=0.0185). This was not statistically significant as compared to a 2-sided significance level of0.00001.

Previously treated NSCLC with EGFR Exon 19 deletions or Exon 21 L858R substitution mutations(MARIPOSA-2)
MARIPOSA-2 is a randomised (2:2:1) open-label, multicentre Phase 3 study in patients with locallyadvanced or metastatic NSCLC with EGFR Exon 19 deletions or Exon 21 L858R substitutionmutations (mutation testing could have been performed at or after the time of locally advanced ormetastatic disease diagnosis. Testing did not need to be repeated at the time of study entry once EGFRmutation status was previously established) after failure of prior therapy including a third-generation
EGFR tyrosine kinase inhibitor (TKI). A total of 657 patients were randomised in the study, of which263 received carboplatin and pemetrexed (CP); and 131 which received Rybrevant in combinationwith carboplatin and pemetrexed (Rybrevant-CP). Additionally, 263 patients were randomised toreceive Rybrevant in combination with lazertinib, carboplatin, and pemetrexed in a separate arm of thestudy. Rybrevant was administered intravenously at 1400 mg (for patients < 80 kg) or 1750 mg (forpatients ≥ 80 kg) once weekly through 4 weeks, then every 3 weeks with a dose of 1750 mg (forpatients < 80 kg) or 2100 mg (for patients ≥ 80 kg) starting at Week 7 until disease progression orunacceptable toxicity. Carboplatin was administered intravenously at area under theconcentration-time curve 5 mg/mL per minute (AUC 5) once every 3 weeks, for up to 12 weeks.
Pemetrexed was administered intravenously at 500 mg/m2 on once every 3 weeks until diseaseprogression or unacceptable toxicity.
Patients were stratified by osimertinib line of therapy (first-line or second-line), prior brain metastases(yes or no), and Asian race (yes or no).
Of the 394 patients randomised to the Rybrevant-CP arm or CP arm, the median age was 62 (range:31-85) years, with 38% of the patients ≥ 65 years of age; 60% were female; and 48% were Asian and46% were White. Baseline Eastern Cooperative Oncology Group (ECOG) performance status was 0(40%) or 1 (60%); 66% never smoked; 45% had history of brain metastasis, and 92% had Stage IVcancer at initial diagnosis.
Rybrevant in combination with carboplatin and pemetrexed demonstrated a statistically significantimprovement in progression-free survival (PFS) compared to carboplatin and pemetrexed, with a HRof 0.48 (95% CI: 0.36, 0.64; p<0.0001). At the time of the second interim analysis for OS, with amedian follow-up of approximately 18.6 months for Rybrevant-CP and approximately 17.8 months for
CP, the OS HR was 0.73 (95%CI: 0.54, 0.99; p=0.0386). This was not statistically significant (testedat a prespecified significance level of 0.0142).

Intracranial metastases efficacy data
Patients with asymptomatic or previously treated and stable intracranial metastases were eligible to berandomised in MARIPOSA-2. Treatment with Rybrevant-CP was associated with a numeric increasein intracranial ORR (23.3% for Rybrevant-CP versus 16.7% for CP, odds ratio of 1.52; 95% CI (0.51,4.50), and intracranial DOR (13.3 months; 95% CI (1.4, NE) in the Rybrevant-CP arm compared with2.2 months; 95% CI (1.4, NE) in the CP arm). The median follow-up for Rybrevant-CP wasapproximately 18.6 months.
Previously-untreated non-small cell lung cancer (NSCLC) with Exon 20 insertion mutations(PAPILLON)
PAPILLON is a randomised, open-label, multicentre Phase 3 study comparing treatment with
Rybrevant in combination with carboplatin and pemetrexed to chemotherapy alone (carboplatin andpemetrexed) in patients with treatment-naïve, locally advanced or metastatic NSCLC with activating
EGFR Exon 20 insertion mutations. Tumour tissue (92.2%) and/or plasma (7.8%) samples for all308 patients were tested locally to determine EGFR Exon 20 insertion mutation status using nextgeneration sequencing (NGS) in 55.5% of patients and/or polymerase chain reaction (PCR) in 44.5%of patients. Central testing was also performed using the AmoyDx® LC10 tissue test, Thermo Fisher
Oncomine Dx Target Test, and the Guardant 360® CDx plasma test.
Patients with brain metastases at screening were eligible for participation once they were definitivelytreated, clinically stable, asymptomatic, and off corticosteroid treatment for at least 2 weeks prior torandomisation.
Rybrevant was administered intravenously at 1400 mg (for patients < 80 kg) or 1750 mg (for patients≥ 80 kg) once weekly through 4 weeks, then every 3 weeks with a dose of 1750 mg (for patients< 80 kg) or 2100 mg (for patients ≥ 80 kg) starting at Week 7 until disease progression orunacceptable toxicity. Carboplatin was administered intravenously at area under the concentration-time curve 5 mg/mL per minute (AUC 5) once every 3 weeks, for up to 12 weeks. Pemetrexed wasadministered intravenously at 500 mg/m2 on once every 3 weeks until disease progression orunacceptable toxicity. Randomisation was stratified by ECOG performance status (0 or 1), and priorbrain metastases (yes or no). Patients randomised to the carboplatin and pemetrexed arm who hadconfirmed disease progression were permitted to cross over to receive Rybrevant monotherapy.
A total of 308 subjects were randomised (1:1) to Rybrevant in combination with carboplatin andpemetrexed (N=153) or carboplatin and pemetrexed (N=155). The median age was 62 (range: 27 to92) years, with 39% of the subjects ≥ 65 years of age; 58% were female; and 61% were Asian and36% were White. Baseline Eastern Cooperative Oncology Group (ECOG) performance status was 0(35%) or 1 (64%); 58% never smoked; 23% had history of brain metastasis and 84% had Stage IVcancer at initial diagnosis.
The primary endpoint for PAPILLON was PFS, as assessed by BICR. The median follow-up was14.9months (range: 0.3 to 27.0).

Previously-treated non-small cell lung cancer(NSCLC) with Exon 20 insertion mutations(CHRYSALIS)
CHRYSALIS is a multicentre, open-label, multi-cohort study conducted to assess the safety andefficacy of Rybrevant in patients with locally advanced or metastatic NSCLC. Efficacy was evaluatedin 114 patients with locally advanced or metastatic NSCLC who had EGFR Exon 20 insertionmutations, whose disease had progressed on or after platinum-based chemotherapy, and who had amedian follow-up of 12.5 months. Tumour tissue (93%) and/or plasma (10%) samples for all patientswere tested locally to determine EGFR Exon 20 insertion mutation status using next generationsequencing (NGS) in 46% of patients and/or polymerase chain reaction (PCR) in 41% of patients; for4% of patients, the testing methods were not specified. Patients with untreated brain metastases or ahistory of ILD requiring treatment with prolonged steroids or other immunosuppressive agents withinthe last 2 years were not eligible for the study. Rybrevant was administered intravenously at 1050 mgfor patients < 80 kg or 1400 mg for patients ≥ 80 kg once weekly for 4 weeks, then every 2 weeksstarting at Week 5 until loss of clinical benefit or unacceptable toxicity. The primary efficacy endpointwas investigator-assessed overall response rate (ORR), defined as confirmed complete response (CR)or partial response (PR) based on RECIST v1.1. In addition, the primary endpoint was assessed by ablinded independent central review (BICR). Secondary efficacy endpoints included duration ofresponse (DOR).
The median age was 62 (range: 36-84) years, with 41% of the patients ≥ 65 years of age; 61% werefemale; and 52% were Asian and 37% were White. The median number of prior therapies was 2(range: 1 to 7 therapies). At baseline, 29% had Eastern Cooperative Oncology Group (ECOG)performance status of 0 and 70% had ECOG performance status of 1; 57% never smoked; 100% had
Stage IV cancer; and 25% had previous treatment for brain metastases. Insertions in Exon 20 wereobserved at 8 different residues; the most common residues were A767 (22%), S768 (16%), D770(12%), and N771 (11%).

Paediatric populationThe European Medicines Agency has waived the obligation to submit the results of studies with
Rybrevant in all subsets of the paediatric population in non-small cell lung cancer (see section 4.2 forinformation on paediatric use).
5.2 Pharmacokinetic properties
Based on Rybrevant monotherapy data, amivantamab area under the concentration-time curve(AUC1 week) increases proportionally over a dose range from 350 to 1750 mg.
Based on simulations from the population pharmacokinetic model, AUC1 week was approximately2.8-fold higher after the fifth dose for the 2-week dosing regimen and 2.6-fold higher after the fourthdose for the 3-week dosing regimen. Steady-state concentrations of amivantamab were reached by
Week 13 for both the 3-week and 2-week dosing regimen and the systemic accumulation was 1.9-fold.
DistributionBased on the individual amivantamab PK parameter estimates in population PK analysis, thegeometric mean (CV%) total volume of distribution, is 5.12 (27.8%) L, following administration ofthe recommended dose of Rybrevant.
EliminationBased on the individual amivantamab PK parameter estimates in population PK analysis, thegeometric mean (CV%) linear clearance (CL) and terminal half-life associated with linear clearance is0.266 (30.4%) L/day and 13.7 (31.9%) days respectively.
Special populationsElderlyNo clinically meaningful differences in the pharmacokinetics of amivantamab were observed based onage (21-88 years).
Renal impairmentNo clinically meaningful effect on the pharmacokinetics of amivantamab was observed in patientswith mild (60 ≤ creatinine clearance [CrCl] < 90 mL/min), moderate (29 ≤ CrCl < 60 mL/min) orsevere (15 ≤ CrCl < 29 mL/min) renal impairment. Data in patients with severe renal impairment arelimited (n=1), but there is no evidence to suggest that dose adjustment is required in these patients.
The effect of end-stage renal disease (CrCl < 15 mL/min) on amivantamab pharmacokinetics isunknown.
Hepatic impairmentChanges in hepatic function are unlikely to have any effect on the elimination of amivantamab since
IgG1-based molecules such as amivantamab are not metabolised through hepatic pathways.
No clinically meaningful effect in the pharmacokinetics of amivantamab was observed based on mild[(total bilirubin ≤ ULN and AST > ULN) or (ULN < total bilirubin ≤ 1.5 x ULN)] or moderate(1.5×ULN < total bilirubin ≤ 3×ULN and any AST) hepatic impairment. Data in patients withmoderate hepatic impairment are limited (n=1), but there is no evidence to suggest that doseadjustment is required in these patients. The effect of severe (total bilirubin > 3 times ULN) hepaticimpairment on amivantamab pharmacokinetics is unknown.
Paediatric populationThe pharmacokinetics of Rybrevant in paediatric patients have not been investigated.
5.3 Preclinical safety data
Non-clinical data reveal no special hazard for humans based on conventional studies of repeated dosetoxicity.
Carcinogenicity and mutagenicityNo animal studies have been performed to establish the carcinogenic potential of amivantamab.
Routine genotoxicity and carcinogenicity studies are generally not applicable to biologicpharmaceuticals as large proteins cannot diffuse into cells and cannot interact with DNA orchromosomal material.
Reproductive toxicologyNo animal studies have been conducted to evaluate the effects on reproduction and foetaldevelopment; however, based on its mechanism of action, amivantamab can cause foetal harm ordevelopmental anomalies. As reported in the literature, reduction, elimination, or disruption of embryofoetal or maternal EGFR signaling can prevent implantation, cause embryo foetal loss during variousstages of gestation (through effects on placental development), cause developmental anomalies inmultiple organs or early death in surviving foetuses. Similarly, knock out of MET or its ligandhepatocyte growth factor (HGF) was embryonic lethal due to severe defects in placental development,and foetuses displayed defects in muscle development in multiple organs. Human IgG1 is known tocross the placenta; therefore, amivantamab has the potential to be transmitted from the mother to thedeveloping foetus.

6.6 Special precautions for disposal and other handling
Prepare the solution for intravenous infusion using aseptic technique as follows:
Preparation- Determine the dose required and the number of Rybrevant vials needed based on patient’sbaseline weight (see section 4.2). Each vial contains 350 mg of amivantamab.
- For every 2-week dosing, patients < 80 kg receive 1050 mg and for patients ≥ 80 kg, 1400 mgonce weekly for a total of 4 doses, then every 2 weeks starting at Week 5.
- For every 3-week dosing, patients < 80 kg receive 1400 mg once weekly for a total of 4 doses,then 1750 mg every 3 weeks starting at Week 7, and for patients ≥ 80 kg, 1750 mg once weeklyfor a total of 4 doses, then 2100 mg every 3 weeks starting at Week 7.
- Check that the Rybrevant solution is colourless to pale yellow. Do not use if discolouration orvisible particles are present.
- Withdraw and then discard a volume of either 5% glucose solution or sodium chloride 9 mg/mL(0.9%) solution for injection from the 250 mL infusion bag that is equal to the required volumeof Rybrevant solution to be added (discard 7 mL diluent from the infusion bag for each vial).
Infusion bags must be made of polyvinylchloride (PVC), polypropylene (PP), polyethylene(PE), or polyolefin blend (PP+PE).
- Withdraw 7 mL of Rybrevant from each vial needed then add it to the infusion bag. Each vialcontains a 0.5 mL overfill to ensure sufficient extractable volume. The final volume in theinfusion bag should be 250 mL. Discard any unused portion left in the vial.
- Gently invert the bag to mix the solution. Do not shake.
- Visually inspect for particulate matter and discolouration prior to administration. Do not use ifdiscolouration or visible particles are observed.
Administration- Administer the diluted solution by intravenous infusion using an infusion set fitted with a flowregulator and with an in-line, sterile, non-pyrogenic, low protein-binding polyethersulfone(PES) filter (pore size 0.22 or 0.2 micrometer). Administration sets must be made of eitherpolyurethane (PU), polybutadiene (PBD), PVC, PP, or PE.
- The administration set with filter must be primed with either 5% glucose solution or 0.9%sodium chloride solution prior to the initiation of each Rybrevant infusion.
- Do not infuse Rybrevant concomitantly in the same intravenous line with other agents.
- The diluted solution should be administered within 10 hours (including infusion time) at roomtemperature (15°C to 25°C) and in room light.
- Due to the frequency of IRRs at the first dose, amivantamab should be infused via a peripheralvein at Week 1 and Week 2; infusion via a central line may be administered for subsequentweeks when the risk of IRR is lower. See infusion rates in section 4.2.
DisposalThis medicinal product is for single use only and any unused medicinal product that is notadministered within 10 hours should be disposed of in accordance with local requirements.
