Further analyses from the Phase 1/1b CHRYSALIS-2 study showed patients with osimertinib pre-treated EGFR-mutated lung cancer who have a MET positive biomarker had an overall response rate of 61 percent and a median PFS of 12.2 months when treated with the chemotherapy-free combination of RYBREVANT® and lazertinib
Updated safety analysis from the Phase 1 PALOMA study evaluating subcutaneous delivery of RYBREVANT® showed shorter administration time and a marked reduction in the incidence and severity of infusion-related reactions
CHICAGO, June 4, 2023 /PRNewswire/ — The Janssen Pharmaceutical Companies of Johnson & Johnson today announced long-term results from the CHRYSALIS study, which showed the combination of RYBREVANT® (amivantamab-vmjw) and lazertinib*, a third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI), was associated with sustained antitumor activity as a first-line treatment in patients with EGFR-mutated non-small cell lung cancer (NSCLC) (Abstract #9134).1 These findings and additional data, including an analysis of predictive biomarkers from Cohort D of the Phase 1/1b CHRYSALIS-2 study evaluating a chemotherapy-free regimen of RYBREVANT® in combination with lazertinib (Abstract #9013)2 and updated safety results from the Phase 1 PALOMA study evaluating the subcutaneous (SC) administration of RYBREVANT® as a monotherapy (Abstract #9126)3 were presented at the 2023 American Society of Clinical Oncology (ASCO) Annual Meeting.
Patients enrolled in the treatment-naïve cohort from the ongoing CHRYSALIS (NCT02609776) study had NSCLC characterized by either an EGFR exon 19 deletion (ex19del) (n=11) or L858R mutation (n=9).1,4 After a median follow-up of nearly three years (33.6 months), the median duration of response (DOR), median progression-free survival (PFS) and overall survival (OS) were not yet reached. The estimated PFS rate was 85 percent after one year, 65 percent at two years and 51 percent at three years. The longest ongoing duration of treatment is over three years (37.2 months), and longest DOR is nearly three years (35.7 months).1
Safety among patients in this cohort was consistent with previous reports and no new safety signals were identified. Treatment-related dose interruptions, reductions and discontinuations of either RYBREVANT® or lazertinib occurred in seven patients (35 percent), eight patients (40 percent) and one patient (5 percent), respectively.1
“Advanced NSCLC and EGFR-mutated lung cancer has a five-year survival rate of less than 20 percent, underscoring an urgent need for more targeted treatment options, especially in earlier lines of therapy,” 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 data for amivantamab and lazertinib introduce the potential for this combination therapy to be used as first-line treatment for this patient population.”
New Analyses on Predictive Biomarkers for Response to RYBREVANT® and Lazertinib Combination Therapy
Patients with advanced NSCLC harboring common EGFR mutations including ex19del or L858R who have experienced disease progression on or after osimertinib are a population with substantial unmet medical need. There are no approved targeted therapies, and the standard of care is platinum-doublet chemotherapy. Data from Cohort D of the Phase 1/1b CHRYSALIS-2 study, which enrolled such patients, were highlighted in an oral presentation at ASCO this year. CHRYSALIS-2 (NCT04077463) is an open-label study to evaluate the safety and pharmacokinetics of lazertinib as monotherapy or in combination with RYBREVANT®.5 Consistent with a prior presentation at ASCO 2021, these data indicate that immunohistochemical (IHC) staining (a testing method using antibodies to determine the relative level of certain antigens or markers in cancer tissue samples) for MET may identify patients more likely to benefit from treatment with the combination of RYBREVANT® and lazertinib.2,6 Among patients with MET overexpression as identified by immunohistochemistry, the response rate was 61 percent with a median PFS of 12.2 months. In contrast, patients with low MET expression had a response rate of 14 percent with a median PFS of 4.2 months.2
Updated Safety Data from the Phase 1 PALOMA Study Evaluating the Investigational Use of Subcutaneous RYBREVANT®
Results from the Phase 1 PALOMA study were featured in a poster presentation and showed RYBREVANT® SC dose was administered on the first day in less than seven minutes, removing the need for split dosing.3 The current approved RYBREVANT® intravenous (IV) infusion dosing is split over two days, with infusion times of approximately 4 to 6 hours for the RYBREVANT® 1050 mg and 1400 mg dose, respectively.8 PALOMA (NCT04606381) is an ongoing, open-label, multicenter study assessing the investigational SC administration of RYBREVANT® as a potential treatment for patients with advanced NSCLC.7 Meaningful reductions in the incidence and severity of infusion related reactions (IRRs) were also observed (16 percent [no grade 3 or higher IRR] with SC as compared to 67 percent [two percent grade 3 or higher IRR] previously reported with IV).3
“These data provide further evidence of the potential efficacy and safety profile of RYBREVANT as both monotherapy and combination therapy for the treatment of patients with EGFR-mutated NSCLC and support our commitment to advance personalized treatment regimens in areas of continued unmet need,” said Kiran Patel, M.D., Vice President, Clinical Development, Solid Tumors, Janssen Research & Development, LLC. “We look forward to continuing to evaluate the full potential of RYBREVANT in our ambition to make this novel therapy available earlier in the treatment paradigm for these patients and improve cancer care.”
About the CHRYSALIS Study
CHRYSALIS (NCT02609776) is a Phase 1 open-label, multicenter, first-in-human study to evaluate the safety, pharmacokinetics and preliminary efficacy of RYBREVANT® as a monotherapy and in combinations including with lazertinib, a novel third-generation EGFR TKI, in adults with advanced NSCLC. The study consists of two parts: RYBREVANT® monotherapy and combination dose escalations (Part 1) and RYBREVANT® monotherapy and combination dose expansions (Part 2). The study enrolled 780 patients with advanced NSCLC.4
The treatment-naive cohort of the ongoing CHRYSALIS study enrolled patients with EGFR ex19del or L858R-mutated advanced NSCLC. All patients received 1050 mg of RYBREVANT® intravenously (1400 mg if weighing at least 80 kg or more) and 240 mg of lazertinib orally. Disease response using overall response rate (ORR), per Response Evaluation Criteria in Solid Tumors Version 1.1♦ (RECIST v1.1) as evaluated by Blinded Independent Central Review (BICR), was the primary endpoint. Circulating tumor DNA was analyzed from plasma samples prior to initiation of treatment, at Cycle 3 Day 1, and at end of treatment.1
About the CHRYSALIS-2 Study5
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 combinations with RYBREVANT®, a human bispecific EGFR and cMet antibody in participants with advanced NSCLC. The study enrolled 460 patients with advanced NSCLC.
Cohort D of the ongoing CHRYSALIS-2 study seeks to validate one or both potential biomarker strategies (NGS and IHC), previously identified in Cohort E, in patients with osimertinib-relapsed and chemotherapy-naïve, EGFR ex19del or L858R-mutated NSCLC. Patients receive the recommended Phase 2 dose of lazertinib orally once daily and RYBREVANT® every seven days for the first 28-day cycle and every two weeks thereafter.
About the PALOMA Study7
PALOMA (NCT04606381) is a Phase 1, open-label, multicenter study assessing the feasibility of the SC administration of RYBREVANT® based on safety and pharmacokinetics, and to determine a dose, dose regimen and formulation for RYBREVANT® SC delivery.
In the ongoing PALOMA study, patients with various advanced solid tumors must have progressed after standard-of-care therapy for metastatic disease, be ineligible for, or have declined current standard therapies. In Part 1, the feasibility of SC administration of RYBREVANT® using the available intravenous (IV) formulation (50 mg/mL) at the recommended Phase 2 dose for IV administration, with and without recombinant human hyaluronidase (rHuPH20), will be assessed. In Part 2, dose escalation will be evaluated using a high-concentration formulation (160 mg/mL) of RYBREVANT®, with and without rHuPH20. This study is also evaluating administration of the full dose of RYBREVANT® on the first day.
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.8 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.
