PhI/II Study of Amivantamab and Tepotinib Combo in MET-altered Non-small Cell Lung Cancer

An Open-Label Phase I/II Study to Evaluate the Safety and prelimiBasnary Efficacy of Amivantamab and Tepotinib Combination in MET-altered Non-small Cell Lung Cancer (NSCLC)

To learn if the combination of amivantamab and tepotinib can help to control NSCLC. The safety of this drug combination will also be studied.

Study Overview

• Status: Active, not recruiting
• Conditions: Non-small Cell Lung Cancer
• Intervention / Treatment: Drug: Amivantamab; Drug: Tepotinib

Detailed Description

Primary Objectives:

1. For the safety run-in portion of the trial:
2. To evaluate dose-limiting toxicity (DLT) and to establish the recommended phase II dose (RP2D) of amivantmab given in combination with tepotinib in patients with advanced MET-altered NSCLC. The primary endpoint is dose-limiting toxicity (DLT) and recommended phase 2 dose (RP2D).
3. For the efficacy portion of the trial:
4. To preliminarily assess efficacy of amivantamab + tepotinib combination in cohort A (MET exon 14 skipping TKI-naïve) , in terms of objective response rate.

Secondary Objectives

1. Determine whether amivantamab + tepotinib improves objective response rate in each cohort (cohort B and cohort C)
2. Determine whether amivantamab + tepotinib improves disease control rate (DCR) in each cohort
3. Determine whether amivantamab + tepotinib improves Duration of Response (DoR) in each cohort
4. Determine the safety and tolerability of amivantamab + tepotinib in each cohort

Exploratory Objectives

1. Explore the association of baseline genomic profiles (from tumor, germline DNA, and ctDNA) with clinical benefit in patients treated with amivantamab + tepotinib
2. Explore resistance mechanisms to amivantamab + tepotinib combination. At the time of progression, patients will undergo ctDNA genomic tests and a biopsy (optional). The purpose of this additional tissue acquisition is for molecular analysis and comparison with the initial specimen, to determine if there are changes in molecular alterations or pathways that shed light on mechanisms of resistance.
3. Determine the immunomodulatory effects of amivantamab + tepotinib combination.

6. Eastern Cooperative Oncology Group (ECOG) performance status 0-1
7. Measurable disease per RECIST 1.1.

12. A woman of childbearing potential must have a negative serum pregnancy test at screening and within 7 days of the first dose of study treatment and must agree to further serum or urine pregnancy tests during the study.

13. A woman must be compliant with the Contraceptive Guidance and Collection of Pregnancy Information:

    1. Not of childbearing potential
    2. Of child-bearing potential and practicing true abstinence during the entire period of the study, including up to 6 months after the last dose of study treatment is given
    3. Of childbearing potential and practicing 2 methods of contraception, including 1 highly effective user independent method and a second method.

    Participant must agree to continue contraception throughout the study and through 6 months after the last dose of study treatment.

    • Note: If the childbearing potential changes after start of the study (eg, woman who is not heterosexually active becomes active, premenarchal woman experiences menarche) the woman must begin birth control, as described above.

14. A woman must agree not to donate eggs (ova, oocytes) for the purposes of assisted reproduction during the study and for 6 months after receiving the last dose of study treatment.
