Updated Amivantamab and Lazertinib Combination Data Demonstrate Durable Responses and Clinical Activity for Osimertinib-Relapsed Patients with EGFR-Mutated Non-Small Cell Lung Cancer

May 19, 2021 (RARITAN, N.J.) – The Janssen Pharmaceutical Companies of Johnson & Johnson today announced updated data from the Phase 1 CHRYSALIS study showing treatment with amivantamab in combination with lazertinib led to a median duration of response (DOR) of 9.6 months in chemotherapy-naïve patients with non-small cell lung cancer (NSCLC) and epidermal growth factor receptor (EGFR) exon 19 deletion or L858R mutations whose disease had progressed after treatment with osimertinib.[1] These data, which will be presented in an oral presentation at the 2021 American Society of Clinical Oncology (ASCO) Annual Meeting on Friday, June 4, also provide new insights on the importance of biomarkers to identify a subgroup of patients more likely to respond to amivantamab and lazertinib (Abstract #9006). Results from the CHRYSALIS study have led to new studies to further evaluate the potential of amivantamab and lazertinib combination therapy, which include the Phase 3 MARIPOSA study and Phase 1/1b CHRYSALIS-2 study.[2],[3]“Typically, patients whose disease no longer responds to osimertinib therapy would have little opportunity to seek additional treatments, other than chemotherapy. However, the durable responses we are seeing with the combination of amivantamab and lazertinib suggest an additional targeted option may be possible,” said Byoung Chul Cho, M.D., Ph.D., Yonsei Cancer Center, Yonsei University College of Medicine in Seoul, South Korea, and lead study investigator...
