Janssen to Highlight Commitment to Lung Cancer Science and Innovation with Eight Data Presentations at the International Association for the Study of Lung Cancer's 2020 World Conference on Lung Cancer

RARITAN, N.J., Jan. 12, 2021 /PRNewswire/ -- The Janssen Pharmaceutical Companies of Johnson & Johnson announced today that eight company-sponsored presentations, including two oral presentations, will be featured at the International Association for the Study of Lung Cancer's (IASLC) 2020 World Conference on Lung Cancer (WCLC) Singapore taking place virtually January 28-31, 2021. The presentations include updated data from the Phase 1 CHRYSALIS study (NCT02609776) evaluating amivantamab in patients with NSCLC and EGFR exon 20 insertion mutations and two studies that characterize the high unmet need and lack of standard of care in patients with exon 20 insertion mutations and the underdiagnosis of these patients in real-world settings.

Amivantamab is an investigational, fully human bispecific antibody that targets tumors by directing immune cell activity against tumors with activating and resistance EGFR mutations and mesenchymal epithelial transition factor (MET) mutations and amplifications.^1,2,3,4  Janssen has filed regulatory submissions in the U.S. and Europe seeking approval of amivantamab for the treatment of patients with NSCLC and EGFR exon 20 insertion mutations whose disease has progressed on or after platinum-based chemotherapy.⁵ These applications mark the first-ever regulatory submissions of a treatment for patients with NSCLC and EGFR exon 20 insertion mutations.⁶ 

"We see an important opportunity to improve the diagnosis and treatment of patients with EGFR-mutated non-small cell lung cancer, especially for individuals with exon 20 insertion mutations. To that end, we look forward to presenting data highlighting the potential of amivantamab in this patient population, and the importance of genetic testing to identify mutations that may impact treatment outcomes," said Kiran Patel, M.D., Vice President, Clinical Development, Solid Tumors, Janssen Research & Development, LLC. "We are focused and committed to transforming the trajectory of lung cancer through improved diagnostics, novel therapeutics and interception strategies."

Lung cancer is one of the most common cancers and is the leading cause of cancer deaths worldwide, with NSCLC making up 80 to 85 percent of all lung cancers.^7,8 Patients with EGFR exon 20 insertion mutations have a median survival of less than 17 months⁹, which is much shorter than patients with EGFR exon 19 deletions or L858R mutations, who have a median survival of 32-39 months on current therapies.¹⁰

Amivantamab Phase 1 CHRYSALIS Study Shows Promise for Patients with NSCLC and EGFR Exon 20 Insertion Mutations
New data from the Phase 1 CHRYSALIS study evaluating the safety and efficacy of amivantamab in patients with metastatic NSCLC and EGFR exon 20 insertion mutations whose disease has progressed on or after platinum-based chemotherapy will be presented as an oral presentation (Abstract #3031). Early results from the CHRYSALIS study were presented at the American Society of Clinical Oncology (ASCO) 2020 Virtual Scientific Program (Abstract #9512).¹¹ 

Mini-Oral Presentation Underscores Unmet Need of Patients with EGFR Exon 20 Insertion Mutations  
A mini-oral presentation based on real-world data will provide new insights into the differences in prognoses for patients with NSCLC and EGFR exon 20 insertion mutations compared to those with other EGFR mutations (Abstract #3390).

Real-World Datasets Spotlight Underdiagnosis for Patients with Lung Cancer with Genetic Alterations
Accurate identification of driver mutations is an important part of lung cancer diagnostic and staging processes.¹² A new analysis of real-world genomic data that will be presented at the meeting (Abstract #3399) estimates that genetic tests using polymerase chain reaction (PCR) may miss up to 50 percent of tumors with EGFR exon 20 insertion mutations, suggesting significant underdiagnosis exists.   

Further details about these data and the science that Janssen is advancing for patients with lung cancer will be made available throughout the IASLC 2020 WCLC via the Janssen Oncology Virtual Newsroom.

Company-sponsored abstracts to be presented at the meeting include:

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.^1,2,3,4  Companion diagnostics using Next Generation Sequencing, which are necessary to identify patients with EGFR exon 20 insertion mutations, have been an integral part of the development program for amivantamab. The bispecific antibody is being studied as a monotherapy in patients with EGFR exon 20 insertion mutations. Amivantamab is also being studied in combination with lazertinib, a third-generation tyrosine kinase inhibitor (TKI)¹³, in adult patients with advanced NSCLC.¹⁴ The production and development of the antibody followed Janssen Biotech, Inc.'s licensing agreement with Genmab for use of its DuoBody^® technology platform. 

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 Interim safety and efficacy results from the lazertinib Phase 1-2 study were published in The Lancet Oncology in 2019. 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 (NSCLC)
Worldwide, lung cancer is one of the most common cancers, and NSCLC makes up 80 to 85 percent of all lung cancers.^7,8 The main subtypes of NSCLC are adenocarcinoma, squamous cell carcinoma and large cell carcinoma.⁸ Among the most common driver mutations in NSCLC are alterations in EGFR, which is a receptor tyrosine kinase supporting cell growth and division.¹⁶ 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.¹⁷ The five-year survival rate for all patients with metastatic NSCLC and EGFR mutations treated with EGFR TKIs is less than 20 percent.^18,19 Estimated median overall survival for patients with NSCLC and EGFR exon 20 insertion mutations is shorter than in patients with common EGFR mutations.¹⁶
