Data presented at WCLC showed combining RYBREVANT ®, lazertinib and chemotherapy may address the diverse resistance that emerges after disease progression on osimertinib
SINGAPORE, Sept. 11, 2023 /PRNewswire/ -- The Janssen Pharmaceutical Companies of Johnson & Johnson today announced follow-up results from the Phase 1b/2 CHRYSALIS-2 study cohort evaluating the safety and tolerability of the combination of RYBREVANT® (amivantamab-vmjw), a bispecific antibody targeting epidermal growth factor receptor (EGFR) and mesenchymal-epithelial transition (MET), with lazertinib, an oral third-generation EGFR tyrosine kinase inhibitor (TKI), plus platinum-based chemotherapy (carboplatin and pemetrexed) in patients with relapsed/refractory non-small cell lung cancer (NSCLC) and EGFR mutations. These findings are being presented at the International Association for the Study of Lung Cancer (IASLC) 2023 World Congress on Lung Cancer (WCLC) from September 9-12 in Singapore.1
"Often, patients with EGFR-mutated NSCLC develop resistance to treatment during the course of therapy. Resistance in patients is typically diverse and polyclonal, meaning their tumors can have more than one type of resistance caused by different pathways. These variables can make their disease much harder to control and treat with targeted therapy alone," said Se-Hoon Lee,* M.D., Ph.D., professor of medicine at the Samsung Medical Center and Sungkyunkwan University School of Medicine and presenting author. "These long-term follow-up data from the CHRYSALIS-2 study in patients with previously treated EGFR-mutated NSCLC demonstrate the importance of treatment strategies that combine chemotherapy with targeted therapy to better address complex resistance patterns after treatment with third-generation EGFR TKIs."
CHRYSALIS-2 (NCT04077463) is an ongoing, multicohort, clinical study evaluating RYBREVANT® in combination with lazertinib in patients with advanced NSCLC with EGFR exon 19 deletion mutations (ex19del) or L858R activating mutations.2 One cohort of CHRYSALIS-2 evaluated the combination of RYBREVANT® and lazertinib with platinum-based chemotherapy in patients with EGFR-mutated advanced NSCLC who experienced disease progression on EGFR TKIs, a regimen similar to the one being evaluated in the ongoing MARIPOSA-2 study. Results from the RYBREVANT®, lazertinib and chemotherapy combination cohort (n=20), were featured in a mini oral presentation (Abstract #MA13.06) at the IASLC 2023 WCLC. Enrolled patients received a median of two prior lines of therapy. Prior therapies included osimertinib (70 percent) and first- and second-generation EGFR TKIs (45 percent).1
The combination of RYBREVANT® and lazertinib with chemotherapy yielded an objective response rate of 50 percent, with 11 out of 20 patients remaining on treatment. Median duration of response was not reached after a median follow-up of 13.1 months. Median progression-free survival (PFS) was 14 months. Eight of 10 responders had a response duration of at least six months. Five patients were treated beyond progression, with a median incremental treatment duration of 4.2 months. The most common treatment-emergent adverse events included low white blood cell count (neutropenia; 90 percent), rash (75 percent) and infusion-related reactions (65 percent).1
"The strong anti-tumor activity of RYBREVANT in EGFR-driven cancers reinforces the utility of this targeted, bispecific therapy in patients whose tumors are resistant," said Kiran Patel, M.D., Vice President, Clinical Development, Solid Tumors, Janssen Research & Development, LLC. "These results provide important insights into the treatment of patients with advanced non-small cell lung cancer with EGFR-mutated disease who have progressed on the current standard of care. We look forward to upcoming late-stage Phase 3 study readouts."
About the CHRYSALIS-2 Study
CHRYSALIS-2 (NCT04077463) is an open-label Phase 1/1b study to evaluate the safety and pharmacokinetics of lazertinib, a third generation EGFR-TKI, as monotherapy or in combination with RYBREVANT®, a human bispecific EGFR and c-MET antibody in participants with advanced NSCLC. The study enrolled 460 patients with advanced NSCLC.2
About RYBREVANT®
RYBREVANT® (amivantamab-vmjw) received accelerated approval by the U.S. Food and Drug Administration (FDA) in May 2021 for the treatment of adult patients with locally advanced or metastatic NSCLC with EGFR exon 20 insertion mutations, as detected by an FDA-approved test, whose disease has progressed on or after platinum-based chemotherapy.3 This indication is approved under accelerated approval based on overall response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in the confirmatory trials. RYBREVANT® has also received approval from health authorities in Europe, as well as other markets around the world.
The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines®) for Non-Small Cell Lung Cancer◊ prefer NGS-based strategies over PCR-based approaches for the detection of EGFR exon 20 insertion variants and include amivantamab-vmjw (RYBREVANT®) as a subsequent therapy option with a Category 2A recommendation for patients that have progressed on or after platinum-based chemotherapy with or without immunotherapy and have EGFR exon 20 insertion mutation-positive advanced NSCLC.4†^
In addition to the Phase 1b/2 CHRYSALIS-2 study, RYBREVANT® is being studied in multiple clinical trials in NSCLC, including:

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. An analysis of the efficacy and safety of lazertinib from the Phase 3 study was published in The Journal of Clinical Oncology in 2023.14 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
Worldwide, lung cancer is one of the most common cancers, with NSCLC making up 80 to 85 percent of all lung cancer cases.15,16 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.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.19,20,21,22,23 EGFR ex19del or EGFR L858R mutations are the most common EGFR mutations.24 The five-year survival rate for all people with advanced NSCLC and EGFR mutations treated with EGFR TKIs is less than 20 percent.25,26
