A Study of Lazertinib as Monotherapy or in Combination With Amivantamab in Participants With Advanced Non-small Cell Lung Cancer (Chrysalis-2)

An Open-label Phase 1/1b Study to Evaluate the Safety and Pharmacokinetics of JNJ-73841937 (Lazertinib), a Third Generation EGFR-TKI, as Monotherapy or in Combinations With JNJ-61186372, a Human Bispecific EGFR and cMet Antibody in Participants With Advanced Non-Small Cell Lung Cancer

The purpose of this study is to confirm the tolerability of recommended Phase 2 dose (RP2D) of Lazertinib (Phase 1), to determine the tolerability and identify the recommended Phase 2 combination dose of Lazertinib when combined with Amivantamab (JNJ-61186372) (Phase 1b), to characterize the safety and tolerability of Lazertinib and Amivantamab combinations at the RP2CD in participants with advanced non-small cell lung cancer (NSCLC) with documented advanced or metastatic epidermal growth factor receptor (EGFR) mutation (Phase 1b expansion cohorts A, B, C, D and E), to estimate the antitumor activity of Lazertinib and Amivantamab combinations at the RP2CD in participants with advanced NSCLC with documented advanced or metastatic EGFR mutation (Phase 1b expansion cohorts A, B, C, and D), to validate the biomarker identified in Phase 1b expansion Cohort D as a predictor of antitumor activity of Lazertinib and Amivantamab combination (Cohort E) or Amivantamab monotherapy (Cohort F) in participants with osimertinib-relapsed, chemotherapy-naïve, EGFR Exon19del or L858R mutated NSCLC, to identify the recommended Phase 2 dose (RP2ChD) of Lazertinib when combined with Amivantamab and standard of care chemotherapy and to determine the tolerability of the Lazertinib, Amivantamab, and platinum-doublet chemotherapy (LACP) combination (Phase 1b LACP combination cohort) and to characterize the safety and tolerability of Lazertinib at the RP2ChD and Amivantamab and standard of care chemotherapy in participants with advanced or metastatic EGFR-mutated NSCLC (Phase 1b LACP combination cohort), to assess 2 potential biomarker strategies to identify participants at increased, or decreased, probability of tumor response with JNJ-61186372 and lazertinib combination in participants with EGFR Exon19del or L858R mutated NSCLC progressed on or after osimertinib (Phase 1b expansion Cohort D).

Study Overview

• Status: Recruiting
• Conditions: Carcinoma, Non-Small-Cell Lung
• Intervention / Treatment: Drug: Lazertinib; Drug: Amivantamab; Drug: Carboplatin; Drug: Pemetrexed

Detailed Description

Lung cancer is one of the most common types of cancer and is also the most common cause of death from cancer. NSCLC accounts for 85 percent (%) to 90% of lung cancers. Lazertinib is an oral, highly potent, mutant-selective, and irreversible EGFR-tyrosine kinase inhibitor (TKI) targeting both, the T790M mutation and activating EGFR mutations while sparing wild type EGFR. JNJ-61186372 (also referred to as amivantamab), is a low fucose, fully human immunoglobulin G1(IgG1)-based bispecific antibody. As a third generation EGFR-TKI targeting activating EGFR mutations, lazertinib has a distinct mechanism of action from JNJ-61186372, which targets the extracellular domains of both the EGFR and cMet proteins. The distinct mechanisms of action of lazertinib and JNJ-61186372 suggests potential to improve clinical outcomes through the combination of these two molecules. Phase 1 and 1b lazertinib + amivantamab, and Phase 1b LACP combination cohort are divided into 2 periods: screening and treatment period whereas Phase 1b expansion cohorts are divided into 3 periods: screening, treatment, and post-treatment follow up period. Safety assessment will include adverse events (AEs), serious adverse events (SAEs), physical examinations, Eastern Cooperative Oncology Group (ECOG) criteria for performance status, laboratory tests, vital signs, electrocardiograms, chest x-ray, baseline ophthalmologic examination (Phase 1b Expansion Cohorts), echocardiography or multigated acquisition, and concomitant medication usage. The overall duration of the study will be up to 5 years and 2 months.

DOR will be calculated as time from initial response of CR or PR to progressive disease (PD) or death due to any cause, whichever comes first, only for participants who achieve CR or PR as determined by the investigator using RECIST 1.1 criteria.	Up to 2.5 years
Clinical Benefit Rate (CBR) Among Participants with MET3+ Staining on >=25% of Tumor Cells (Phase 1b Expansion Cohorts E and F)	CBR among participants with MET3+ staining on >=25% of tumor cells will be reported. CBR is defined as the percentage of participants achieving complete or partial response, or durable stable disease (duration of at least 11 weeks) as determined by the investigator using RECIST 1.1 criteria.	Up to 2.5 years

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Number of Participants with Adverse Events (AEs) as a Measure of Safety and Tolerability (Phase 1 and Phase 1b)	An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study.	Up to 2.5 years
Plasma Concentration of Lazertinib (Phase 1 and Phase 1b)	Plasma samples will be analyzed to determine concentrations of Lazertinib.	Up to End of Treatment [EOT]) (30 days after last dose) (up to 2.5 years)
Serum Concentration of Amivantamab (Phase 1b)	Serum samples will be analyzed to determine concentrations of Amivantamab.	Up to EOT (30 days after last dose) (up to 2.5 years)
Number of Participants with Anti-drug Antibodies Against Amivantamab (Phase 1b)	Number of participants with anti-drug antibodies against Amivantamab will be reported.	Up to EOT (30 days after last dose) (up to 2.5 years)
Progression free survival (PFS) (Phase 1b Expansion)	PFS is defined as the time from first infusion of study intervention to PD or death due to any cause.	Up to 2.5 years
Time to Treatment Failure (TTF) (Phase 1b Expansion)	TTF is defined as the time from the first administration of the study intervention to discontinuation of treatment for any reason, including disease progression, treatment toxicity, death, and will be utilized to capture clinical benefit for patients continuing treatment beyond as determined by the investigator using RECIST 1.1 criteria.	Up to 2.5 years
Overall Survival (OS) (Phase 1b Expansion)	OS is defined as the time from first infusion of study intervention to death due to any cause as determined by the investigator using RECIST 1.1 criteria.	Up to 2.5 years
Duration of Response (DOR) (Phase 1b expansion)	DOR will be calculated as time from initial response of CR or PR to progressive disease (PD) or death due to any cause, whichever comes first, only for participants who achieve CR or PR as determined by the investigator using RECIST 1.1 criteria.	Up to 2.5 years
Clinical Benefit Rate (CBR) (Phase 1b expansion)	CBR is defined as the percentage of participants achieving complete or partial response, or durable stable disease (duration of at least 11 weeks) as determined by the investigator using RECIST 1.1 criteria.	Up to 2.5 years
Number of Participants with Venous Thromboembolic (VTE) Events by Severity	Number of participants with VTE events including pulmonary embolism and deep vein thrombosis by severity defined by the NCI-CTCAE Criteria Version 5.0 will be reported.	Up to 2.5 years
Number of Participants with Adverse Events (AEs) (Phase 1b Expansion Cohort F)	An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study.	Up to 2.5 years
ORR (Phase 1b expansion Cohorts E and F)	ORR is defined as the percentage of participants who achieve either a CR or PR as determined by the investigator using RECIST 1.1 criteria.	Up to 2.5 years
DOR (Phase 1b Expansion Cohorts E and F)	DOR will be calculated as time from initial response of CR or PR to PD or death due to any cause, whichever comes first, only for participants who achieve CR or PR as determined by the investigator using RECIST 1.1 criteria.	Up to 2.5 years
CBR (Phase 1b expansion Cohorts E and F)	CBR is defined as the percentage of participants achieving complete or partial response, or durable stable disease (duration of at least 11 weeks) as determined by the investigator using RECIST 1.1 criteria.	Up to 2.5 years
Intracranial Progression free survival (PFS) (Phase 1b Expansion E and F)	Intracranial PFS is defined as the time from first infusion of study intervention until the date of objective intracranial disease progression or death, whichever comes first, based on Investigator assessment using RECIST v1.1.	Up to 2.5 years
