Expanded Access Program Established for Patients in the U.S. Who May Benefit from Investigational Therapy While Application is Under Review

RARITAN, NJ, USA I December 03, 2020 I The Janssen Pharmaceutical Companies of Johnson & Johnson announced today the submission of a Biologics License Application (BLA) to the U.S. Food and Drug Administration (FDA) seeking approval of amivantamab for the treatment of patients with metastatic non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) exon 20 insertion mutations whose disease has progressed on or after platinum-based chemotherapy. The application marks the first-ever regulatory submission for the treatment of patients with NSCLC with EGFR exon 20 insertion mutations.1 The Company has also established an expanded access program (EAP) [NCT04599712]2 for patients in the U.S. who may be eligible to obtain access to amivantamab during review of the BLA. For information about Janssen’s pre-approval access program, visit https://www.janssen.com/compassionate-use-pre-approval-access.

Amivantamab is an investigational, fully-human EGFR and mesenchymal epithelial transition factor (MET) bispecific antibody with immune cell-directing activity that targets tumors with activating and resistance EGFR and MET mutations and amplifications.3,4,5,6 In March 2020, amivantamab received Breakthrough Therapy Designation from the FDA for this population.7

“This submission marks an important step forward in our drive toward evolving the treatment landscape for patients with NSCLC who have EGFR exon 20 insertion mutations and for whom there are no FDA-approved targeted treatment options,” said Peter Lebowitz, M.D., Ph.D., Global Therapeutic Area Head, Oncology, Janssen Research & Development, LLC. “We are committed to the development of therapies like amivantamab that progress precision medicine and target specific pathways, and to providing access through expanded access programs.”

The BLA submission for amivantamab is based on data from the monotherapy arm of the Phase 1 CHRYSALIS study, a multi-center, open-label, multi-cohort study evaluating the safety and efficacy of amivantamab as a monotherapy and in combination with lazertinib*, a novel third-generation EGFR tyrosine kinase inhibitor (TKI)8, in adult patients with advanced NSCLC.9 In the study, investigators assessed efficacy using overall response rate per Response Evaluation Criteria in Solid Tumors Version 1.1** (RECIST v1.1), clinical benefit rate, and duration of response and progression-free survival, as well as the safety profile of amivantamab.8,10 Early data about amivantamab as a monotherapy treatment in patients with NSCLC with EGFR exon 20 insertion mutations were presented at the American Society of Clinical Oncology (ASCO) 2020 Virtual Scientific Program (Abstract #9512).10

“Lung cancer remains the leading cause of cancer deaths worldwide. Given this significant unmet need, we at Johnson & Johnson are committed to improving outcomes for patients diagnosed with this complex, deadly disease. With today’s submission for amivantamab, we are one step closer to that goal,” said Mathai Mammen, M.D., Ph.D., Global Head, Janssen Research & Development, Johnson & Johnson. “We are steadfast in our focus to advance novel therapeutics and medicines that will transform the trajectory of some of the most challenging and deadly diseases of our time, including lung cancer.”

EGFR mutations, leading to uncontrolled cancer cell growth and division11, are some of the most common mutations in NSCLC.12 EGFR exon 20 insertion mutations are the third most prevalent primary EGFR mutation.13 However, EGFR exon 20 insertion mutations are also often undetected.13 Next Generation Sequencing (NGS) is effective at detecting EGFR exon 20 insertion mutations and broader use of NGS can help to detect these mutations.14 Cancer driven by EGFR exon 20 insertion mutations is generally insensitive to approved EGFR TKI treatments and, in addition, carries a worse prognosis compared with cancer driven by more common EGFR mutations, including exon 19 deletions/L858R substitutions.15 Patients with EGFR exon 20 insertion mutations have a median survival of less than 17 months16, which is much shorter than patients with EGFR exon 19 deletions or L858R mutations, who have a median survival of 32-39 months.17

*In 2018, Janssen entered into a license and collaboration agreement with Yuhan Corporation for the development of lazertinib.

**RECIST (version 1.1) refers to Response Evaluation Criteria in Solid Tumors, which is a standard way to measure how well solid tumors respond to treatment and is based on whether tumors shrink, stay the same, or get bigger.

About Amivantamab

Amivantamab is an investigational, fully-human EGFR-MET bispecific antibody with immune cell-directing activity that targets tumors with activating and resistance EGFR mutations and MET mutations and amplifications.3,4,5,6 Amivantamab is pending regulatory review as a potential treatment for patients with NSCLC with EGFR exon 20 insertion mutations whose tumors typically do not respond to current standard of care. Companion diagnostics to identify patients with EGFR exon 20 insertion mutations have been an integral part of the development program for amivantamab. The production and development of the antibody followed Janssen Biotech, Inc.’s licensing agreement with Genmab for use of its DuoBody® technology platform.

About the Amivantamab Expanded Access Program Protocol (EAP)

The amivantamab EAP is for U.S. patients 18 years of age or older who have histologically or cytologically confirmed unresectable or metastatic NSCLC with an EGFR exon 20 insertion mutations who are not amenable to curative therapy and whose disease has progressed during or after current standard of care platinum-based chemotherapy, who may benefit from treatment with amivantamab prior to its potential FDA approval.2 The EAP has specific inclusion and exclusion criteria for patients to be considered for enrollment in the program, and patients must not be eligible for another amivantamab study.2 Interested patients should contact their physician to discuss whether they may be a candidate for amivantamab through the EAP.2 Additional information about the expanded access protocol can be found on clinicaltrials.gov (NCT04599712) and at https://www.janssen.com/compassionate-use-pre-approval-access.

About Non-Small Cell Lung Cancer (NSCLC)

Worldwide, lung cancer is the most common cancer, and NSCLC makes up 80 to 85 percent of all lung cancers.18,19 The main subtypes of NSCLC are adenocarcinoma, squamous cell carcinoma and large cell carcinoma.19 Among the most common driver mutations in NSCLC are alterations in EGFR, which is a receptor tyrosine kinase supporting cell growth and division.11 EGFR mutations are present in 10 to 15 percent of patients with NSCLC and occur in 40 to 50 percent of Asian patients who have NSCLC adenocarcinoma.20 The five-year survival rate for all patients with metastatic NSCLC with EGFR mutations treated with EGFR TKIs is less than 20 percent.21,22 Estimated median overall survival for patients with NSCLC and EGFR exon 20 insertion mutations is shorter than in patients with common EGFR mutations.11
