Patients with EGFR ex19del or EGFR L858R mutations, the most common EGFR mutations in NSCLC, currently face a poor prognosis and limited treatment options after disease progression on osimertinib1,2,3,4
In the MARIPOSA-2 study, amivantamab in combination with chemotherapy significantly reduced the risk of disease progression or death by 52 percent compared to chemotherapy alone, and is the first treatment regimen to show improvement in progression-free survival in this patient population5
BEERSE, BELGIUM , July 26, 2024 (GLOBE NEWSWIRE) -- Janssen-Cilag International NV, a Johnson & Johnson company, today announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) has recommended the approval of a Type II extension of indication for RYBREVANT®▼ (amivantamab) in combination with chemotherapy (carboplatin and pemetrexed), for the treatment of adult patients with advanced non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) Exon 19 deletions (ex19del) or Exon 21 L858R (L858R) substitution mutations, after failure of prior therapy including an EGFR tyrosine kinase inhibitor (TKI).6
“Resistance mechanisms after disease progression on osimertinib are diverse and polyclonal, with up to half being EGFR and MET-based alterations. There are no targeted therapies approved for the post-osimertinib setting, and outcomes with the current standard of care, platinum-based chemotherapy, are poor,” said Antonio Passaro, M.D., Ph.D., Medical Oncologist, Division of Thoracic Oncology at the European Institute of Oncology in Milan, Italy.* “The combination of amivantamab and chemotherapy offers renewed hope and a new standard of care for these patients, with improvements observed in response rates, progression-free survival, and intracranial efficacy, even in patients with previously untreated brain metastases.”
“EGFR gene mutations are the most common actionable oncogenic mutations in NSCLC, with ex19del or L858R mutations representing up to 90 percent of all EGFR mutations,” said Henar Hevia, Ph.D., Senior Director, EMEA Therapeutic Area Lead, Oncology, Johnson & Johnson Innovative Medicine. “At Johnson & Johnson, our dedication to transforming the treatment of lung cancer with innovative therapies is unwavering, and we are proud to take another step forward for patients in need of new, targeted treatment options.”
The CHMP recommendation for amivantamab is supported by data from the Phase 3 MARIPOSA-2 (NCT04988295) study, evaluating the efficacy and safety profile of amivantamab and chemotherapy in patients with locally-advanced or metastatic EGFR ex19del or L858R substitution NSCLC who had disease progression on or after treatment with osimertinib.5 The amivantamab plus chemotherapy arm met its primary endpoint, significantly reducing the risk of disease progression or death by 52 percent, compared to chemotherapy alone, with a median progression-free survival (PFS) of 6.3 months, versus 4.2 months (hazard ratio [HR]=0.48; 95 percent confidence interval [CI], 0.36–0.64; P<0.001).5 Additionally, amivantamab plus chemotherapy showed an objective response rate (ORR) of 64 percent, compared to 36 percent with chemotherapy alone.5
The data from MARIPOSA-2 also showed that amivantamab combination regimens may provide intracranial activity, critical for a disease where nearly 30 percent of patients develop brain metastases.7,8 Specifically, amivantamab plus chemotherapy reduced the risk of intracranial progression or death by 45 percent compared to chemotherapy alone, with a median intracranial progression-free survival of 12.5 versus 8.3 months (HR=0.55; 95 percent CI, 0.38–0.79; P=0.001).5
The safety profile of amivantamab plus chemotherapy is consistent with that of its individual components.5 Adverse events (AEs) of Grade 3 or higher, mainly due to haematologic toxicities, were reported by 72 percent of patients treated with amivantamab plus chemotherapy, and 48 percent with chemotherapy alone.5 The most common Grade 3 or higher AEs included neutropenia, thrombocytopenia, anaemia, and leukopenia.5 Grade 3 or 4 bleeding events were seen in one percent of patients treated with amivantamab plus chemotherapy, and in no patients with chemotherapy.5 Serious treatment-emergent AEs (TEAEs) were observed in 32 percent of patients treated with amivantamab plus chemotherapy and 20 percent with chemotherapy.5 Infusion-related reactions in the amivantamab plus chemotherapy arm were 58 percent (all grades).5 Treatment related AEs leading to death were infrequent in all arms (2 percent vs. 1 percent) in the amivantamab plus chemotherapy and chemotherapy alone arms respectively.5
“Today’s positive CHMP opinion is welcome news and demonstrates the results of our deep commitment to transforming outcomes for patients with NSCLC,” said Kiran Patel, M.D., Vice President, Clinical Development, Solid Tumours, Johnson & Johnson Innovative Medicine. “Amivantamab has already shown positive outcomes in treating patients with other EGFR mutations, and we now look forward to the next steps in making it available to further patients with common EGFR mutations after progression on osimertinib”
Results from MARIPOSA-2 were presented during a Presidential Symposium at the European Society for Medical Oncology (ESMO) 2023 Congress and simultaneously published in the Annals of Oncology.5,7
About MARIPOSA-2
MARIPOSA-2 (NCT04988295), which enrolled 657 patients, is a randomised, open-label Phase 3 study evaluating the efficacy and safety of two combination regimens of amivantamab (with and without lazertinib) and chemotherapy.5 Patients with locally-advanced or metastatic EGFR ex19del or L858R substitution NSCLC who had disease progression on or after treatment with osimertinib were randomised to treatment with amivantamab plus chemotherapy, amivantamab plus chemotherapy with lazertinib, or chemotherapy alone.5 The dual primary endpoint was used to compare the PFS (using RECIST v1.1 guidelines†) as assessed by blinded independent central review (BICR) for each experimental arm to chemotherapy alone.5 Secondary endpoints included objective response as assessed by BICR, overall survival (OS), duration of response (DOR), time to subsequent therapy, PFS2 and intracranial PFS.5
All study participants underwent serial brain imaging to allow for the robust assessment of intracranial endpoints and to assess the CNS activity of amivantamab and doublet chemotherapy with and without lazertinib.5 Because brain metastases can lead to significant burden and poor outcomes for patients, this aspect of the study design provides critical information in an area of high unmet need.8
About Amivantamab
Amivantamab is a fully-human EGFR-MET bispecific antibody that acts by targeting tumours with activating and resistance EGFR mutations and MET mutations and amplifications, and by harnessing the immune system.9,10,11,12
The European Commission (EC) granted conditional marketing authorisation of amivantamab in December 2021, for the treatment of adult patients with advanced NSCLC with activating EGFR exon 20 insertion mutations, after failure of platinum-based therapy.9 In June 2024, the EC granted full marketing authorisation for the use of amivantamab in combination with carboplatin and pemetrexed chemotherapy, for the first-line treatment of adult patients with advanced NSCLC with EGFR exon 20 insertion mutations, based on the PAPILLON study.6 Amivantamab is the first approved treatment in the European Economic Area specifically targeting EGFR exon 20 insertion mutations for NSCLC.13
In February 2024, a Type II extension of indication application was submitted to the EMA based on the MARIPOSA study, for amivantamab in combination with lazertinib, for the first-line treatment of adult patients with advanced (NSCLC with common EGFR ex19del or L858R substitution mutations.13 In May 2024, an application for the extension of amivantamab marketing authorisation was submitted seeking approval for the use of a subcutaneous (SC) formulation of amivantamab in combination with lazertinib for the first-line treatment of adult patients with advanced NSCLC with EGFR ex19del or L858R mutations, and for the use of SC amivantamab monotherapy in adult patients with advanced NSCLC with activating EGFR exon 20 insertion mutations after failure of platinum-based therapy.14

About Lazertinib
Lazertinib is an oral, third-generation, brain-penetrant EGFR TKI that targets both the T790M mutation and activating EGFR mutations while sparing wild-type EGFR.15 An analysis of the efficacy and safety of lazertinib from the Phase 3 LASER301 study was published in The Journal of Clinical Oncology in 2023.15 In 2018, Janssen Biotech, Inc., entered into a license and collaboration agreement with Yuhan Corporation for the development of lazertinib.
About Non-Small Cell Lung Cancer
In Europe, it is estimated that 484,306 people were diagnosed with lung cancer in 2022.16 NSCLC accounts for 85 percent of all lung cancer cases.17 Lung cancer is Europe’s biggest cancer killer, with more deaths than breast cancer and prostate cancer combined.16
The main subtypes of NSCLC are adenocarcinoma, squamous cell carcinoma and large cell carcinoma.17 Among the most common driver mutations in NSCLC are alterations in EGFR, which is a receptor tyrosine kinase controlling cell growth and division.17,18 EGFR mutations are present in 10 to 15 percent of Western patients with NSCLC with adenocarcinoma histology and occur in 40 to 50 percent of Asian patients.19,20,21,22 EGFR ex19del or EGFR L858R mutations are the most common EGFR mutations.23 The five-year survival rate for all people with advanced NSCLC and EGFR mutations treated with EGFR tyrosine kinase inhibitors (TKIs) is less than 20 percent.24
