Study of Amivantamab, a Human Bispecific EGFR and cMet Antibody, in Participants With Advanced Non-Small Cell Lung Cancer (CHRYSALIS)

A Phase 1, First-in-Human, Open-Label, Dose Escalation Study of JNJ-61186372, a Human Bispecific EGFR and cMet Antibody, in Subjects With Advanced Non-Small Cell Lung Cancer

The purpose of study is to evaluate the safety, pharmacokinetics, and preliminary efficacy of Amivantamab as a monotherapy and in combination with lazertinib, and to determine the recommended Phase 2 dose (RP2D) (monotherapy), recommended Phase 2 combination dose (RP2CD) (combination therapy), and to determine recommended Phase 2 Dose (RP2q3W) with combination chemotherapy (Amivantamab in combination with standard of care carboplatin and pemetrexed) in 21 day treatment cycle for participants with advanced non-small cell lung cancer (NSCLC).

Study Overview

• Status: Active, not recruiting
• Conditions: Non-Small-Cell Lung Cancer
• Intervention / Treatment: Drug: Amivantamab; Drug: Amivantamab; Drug: Lazertinib; Drug: Carboplatin; Drug: Pemetrexed

Detailed Description

This open label (all participants know the identity of the study drug), multicenter (more than one study site), first-in-human study consists of 2 parts. Part 1 is a Amivantamab Monotherapy and Combination Dose Escalations and Part 2 Amivantamab Monotherapy and Combination Dose Expansions. In Part 1, participants with evaluable NSCLC will be enrolled into cohorts at increasing dose levels of Amivantamab monotherapy, the RP2CD of the Amivantamab and lazertinib combination which will be administered in 28 day treatment cycles, and RP2q3W of Amivantamab in combination with standard of care carboplatin and pemetrexed (chemotherapy combination) which will be administered in 21 day treatment cycles. The dose will be escalated until the maximum tolerated dose (MTD, or maximum administered dose [MAD], if no MTD is found) is reached. Part 1 will follow a traditional 3+3 design. At each dose level, 3 participants will complete Cycle 1. If no dose limiting toxicity (DLT) occurs in these 3 participants, then escalation will continue in a new cohort of 3 participants. Data from Part 1 will be used to determine one or more RP2D regimen(s). In Part 2, participants with documented epidermal growth factor receptor (EGFR) mutations and measurable disease, whose disease has progressed after previous treatment will be enrolled and receive Amivantamab at the RP2D determined in Part 1 as a monotherapy at the RP2D regimen(s), or in combination with lazertinib at the RP2CD regimen. For both parts, the study consists of following periods: an optional pre-Screening period; a Screening period (up to 28 days prior to the first dose of study drug); a Treatment period (first dose of study drug until 30(+7) days after the last dose of study drug or prior to starting any subsequent anti-cancer treatment, whichever comes first); and a Follow Up period (approximately 6 months). All participants will be followed for survival in the post-treatment follow-up period until the end of study and safety will be monitored throughout the study.

In cases where participants refuse currently available therapeutic options, this must be documented in the study records. For Part 1 Chemotherapy Combination Cohort only: Participants must have histologically or cytologically confirmed NSCLC that is metastatic or unresectable and be eligible for treatment with combination carboplatin and pemetrexed, in accordance with standard of care, and be willing to receive additional investigational therapy with Amivantamab

For Part 1 Chemotherapy Combination Cohort: Participants may be diagnosed with EGFR mutated or EGFR wild type NSCLC. For Part 2 Cohorts C, D, MET-1, and MET-2 only: Participants must also have disease with a previously diagnosed activating epidermal growth factor receptor (EGFR) mutation (includes both inhibitor sensitive primary mutations such as Exon 19 deletion and L858R (Cohort C, E, and MET-1), as well as marketed TKI-resistant mutations such as Exon 20 insertion (Cohort C, D and MET-1) or activating cMet Exon 14 skipping mutation (Cohort MET-2). Documentation of primary activating EGFR or cMet mutation eligibility by CLIA-certified laboratory (or equivalent) testing is required. For Part 2 Cohorts WT-Ad and WT-Sq: Participants must have wild-type EGFR, anaplastic lymphoma kinase (ALK), and absence of MET Exon 14 skipping mutation as tested by the Food and Drug Administration (FDA) approved test or a CLIA-certified laboratory (or equivalent).

Thoracentesis, if needed, and percutaneous biopsy for baseline tumor tissue sample may be done less than 4 weeks prior to Cycle 1 Day 1, as long as the participant has adequately recovered from the procedure prior to the first dose of study drug in the clinical judgement of the investigator; b. Significant traumatic injury within 3 weeks before the start of Cycle 1 Day 1 (all wounds must be fully healed prior to Day 1); c. Any medical condition that requires intact wound healing capacity and is expected to endanger subject safety if wound healing capacity would be severely reduced during administration of the investigational agent; d.
