What this trial studies

This clinical trial investigates the effectiveness of amivantamab in combination with tyrosine kinase inhibitors (TKIs) for patients with advanced non-small cell lung cancer (NSCLC) who have specific genetic alterations (ALK, ROS1, or RET). The study aims to address the issue of acquired resistance to TKIs by targeting both the ERBB and cMet pathways, which may help improve treatment outcomes. Participants must have previously shown clinical progression on at least one TKI and have documented genetic alterations. The trial is designed to evaluate the safety and efficacy of this combination therapy in a phased approach.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with advanced NSCLC harboring ALK, ROS1, or RET fusions who have progressed on prior TKI therapy.

Not a fit: Patients without documented ALK, ROS1, or RET alterations or those who have not previously received TKI therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new effective option for patients with advanced NSCLC who have developed resistance to existing therapies.

How similar studies have performed: Other studies have shown promising results with similar combination therapies targeting resistance pathways in lung cancer, indicating potential for success in this approach.

    1. Have 1 negative pregnancy test as verified by an Investigator prior to starting study therapy. This applies even if the subject practices true abstinence\* from heterosexual contact.
    2. Either commit to true abstinence\* from heterosexual contact (which must be reviewed on a monthly basis) or agree to use and be able to comply with a barrier method plus a hormonal method of contraception without interruption 28 days prior to starting investigational product, during the study therapy (including dose interruptions), and for 3 months after discontinuation (or longer if required by local requirements) of study therapy. The method of contraception must be a barrier method plus a hormonal method to prevent pregnancy.
    3. Participants must agree to continue contraception throughout the study and continuing through 3 months after the last dose of study drug. Note: If the childbearing potential changes after start of the study (e.g., woman who is not heterosexually active becomes active, premenarchal woman experiences menarche) the woman must begin a highly effective method of birth control, as described above.
    4. A woman of childbearing potential must have a negative serum or urine (b- human chorionic gonadotropin \[b-hCG\]) at Screening.
    5. 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 drug.
