RARITAN, NJ, March 10, 2020 -- The Janssen Pharmaceutical Companies of Johnson & Johnson announced today that the U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy Designation for JNJ-61186372 (JNJ-6372) 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. JNJ-6372 is an EGFR-mesenchymal epithelial transition factor (MET) bispecific antibody that targets activating and resistant EGFR and MET mutations and amplifications.[1] Currently, there are no FDA-approved targeted therapies for patients with lung cancer who have EGFR Exon 20 insertion mutations.[2]

Patients with NSCLC and EGFR Exon 20 insertion mutations have a form of disease that is generally insensitive to EGFR tyrosine kinase inhibitor (TKI) treatments and carries a worse prognosis compared to patients with more common EGFR mutations (Exon 19 deletions/L858R substitution).[3] The current standard of care for this patient population is conventional cytotoxic chemotherapy.[4]

“JNJ-6372 is a novel bispecific antibody that we believe has the potential to benefit patients with Exon 20 mutation insertions who often do not respond to currently available oral EGFR-targeted or immune checkpoint inhibitor therapies,” said Peter Lebowitz, M.D., Ph.D., Global Therapeutic Area Head, Oncology, Janssen Research & Development, LLC. “This Breakthrough Therapy Designation is a significant milestone in our ongoing efforts to advance JNJ-6372 in clinical development and target genetically-defined lung cancer.”

The Breakthrough Therapy Designation is supported by data from a Phase 1, first-in-human, open-label, multicenter study (NCT02609776).5 The study evaluates the safety, pharmacokinetics and preliminary efficacy of JNJ-6372 monotherapy and in combination with lazertinib[i], a novel third-generation EGFR TKI, in adult patients with advanced NSCLC.5
The study seeks to determine the recommended Phase 2 dose in patients with advanced NSCLC.[5] Enrollment into the Part 2 dose expansion cohorts is ongoing, as the study evaluates JNJ-6372 monotherapy activity in multiple NSCLC sub-populations with genomic alterations such as those with C797S resistance mutation or MET amplification.5

A U.S. FDA Breakthrough Therapy Designation is granted to expedite the development and regulatory review of an investigational medicine that is intended to treat a serious or life-threatening condition.6 The criteria for Breakthrough Therapy Designation require preliminary clinical evidence that demonstrates the drug may have substantial improvement on at least one clinically significant endpoint over available therapy.[6]

About JNJ-61186372 (JNJ-6372)

JNJ-6372 is an EGFR-MET bispecific antibody with immune cell-directing activity that targets activating and resistant EGFR and MET mutations and amplifications.5,[7] The production and development of the antibody followed Janssen’s licensing agreement with Genmab for use of its DuoBody® technology platform.

About Non-Small Cell Lung Cancer (NSCLC)

In the U.S., lung cancer is the second most common cancer in both men and women, after skin cancer; NSCLC makes up 80-85 percent of all lung cancers.[8],[9] The main subtypes of NSCLC are adenoca rcinoma, squamous cell carcinoma, and large cell carcinoma.10 The most common driver mutation for NSCLC is the EGFR genetic alteration, which is a receptor tyrosine kinase that helps cells grow and divide.[10] 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.[11],[12],[13] EGFR exon 20 insertion mutations identify a distinct subset of lung adenocarcinomas, accounting for at least nine percent of all EGFR mutations.[14] The five-year survival rate for patients with metastatic NSCLC is currently six percent.[15]
