About

The purpose of this study is to identify the recommended Phase 2 (combination) dose (RP2CD) of the amivantamab and cetrelimab combination therapy in participants with non-small cell lung cancer (NSCLC) in Phase 1 (combination dose selection); and to evaluate the antitumor effect of the combination at the selected RP2CD in participants with NSCLC characterized on the basis of epidermal growth factor receptor (EGFR) and Programmed-cell death Ligand (PD-L)1 status, in the Phase 2 (expansion).

Enrollment: 80 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Participant must have histologically or cytologically confirmed non-small cell lung cancer (NSCLC) (any histology), and must have metastatic NSCLC at the time of enrollment: Phase 1 (Combination Dose Selection) Cohort; Metastatic NSCLC progressed on or after standard of care systemic anti-cancer therapy and participant is declining other systemic treatment options, if any;1. Participants without known mutations must have had disease progression on, or have intolerance to, prior platinum-based chemotherapy and PD-(L)1-targeted immunotherapy given concurrently or sequentially, OR 2. Participants with NSCLC characterized by known driver mutations must have had disease progression on, or have intolerance to, appropriate targeted therapies as per local standard of care. Participants may have received prior therapy with amivantamab as long as discontinuation was not due to toxicity. Participants with EGFR mutation must not have had an anti-PD-1/PD-L1 therapy, Phase 2 Expansion Cohorts; Cohort A: Participant's tumor must have an EGFR exon19del or L858R mutation, as determined by local molecular testing, Cohort B: Participants must have tumors lacking known primary driver mutations and must have PD-L1 expression of greater than or equal to (>=)50 percentage (%), per local testing, and are treatment-naïve in the metastatic setting
• Participant must have at least 1 measurable lesion, according to Response Evaluation Criteria in Solid Tumors (RECIST) v1.1, that has not been previously irradiated
• Have an Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1

Exclusion criteria

• Participant has an uncontrolled illness, including but not limited to: a. Uncontrolled diabetes, b. Ongoing or active infection (includes infection requiring treatment with antimicrobial therapy [participants will be required to complete antibiotics 1 week prior to starting study treatment] or diagnosed or suspected viral infection), c. Active bleeding diathesis, d. Impaired oxygenation requiring continuous oxygen supplementation, e. Psychiatric illness or any other circumstances (including social circumstances) that would limit compliance with study requirements
• Medical history of (non-infectious) interstitial lung disease (ILD)/pneumonitis, or has current ILD/pneumonitis, or where suspected ILD/pneumonitis cannot be ruled out by imaging at screening
• Has an active autoimmune disease or a documented history of autoimmune disease that requires systemic steroids or immunosuppressive agents
• Participant has received radiotherapy for palliative purposes less than 14 days prior to the first dose of study treatment
• Participant has a. (or has a history of) leptomeningeal disease (carcinomatous meningitis), b. spinal cord compression not definitively treated with surgery or radiation

Trial design

Primary purpose: Treatment

Allocation: Non-Randomized

Interventional model: Sequential Assignment

Masking: None (Open label)

---

80 participants in 2 patient groups

Phase 1 (Combination Dose Selection)

Experimental group

Description:

Participants will receive amivantamab low dose or high dose intravenous (IV) infusion based on body weight from Cycle 1 Day 1, Day 2, and subsequently Day 8, Day 15, and Day 22 and then every 2 weeks from Cycle 2 in combination with cetrelimab IV infusion from Cycle 1 Day 2 (after the Day 2 infusion of amivantamab). Doses will be escalated or de-escalated based on the dose limiting toxicities (DLTs) and the recommended Phase 2 combination dose (RP2CD) will be determined by the study evaluation team (SET).

Treatment:

Drug: Cetrelimab

Drug: Amivantamab

Phase 2 (Dose Expansion)

Experimental group

Description:

Participants will receive amivantamab in combination with cetrelimab in Cohorts A and B at the RP2CD determined by the SET in Phase 1. Participants will continue study treatment until disease progression, unacceptable toxicity, or until another criterion for discontinuation of study treatment is met.

Treatment:

Drug: Cetrelimab

Drug: Amivantamab
