NCT07221474

Brief Summary

Researchers want to know if intismeran autogene (the study treatment) given with pembrolizumab and chemotherapy can treat metastatic treatment-naive squamous non-small cell lung cancer (NSCLC). Intismeran autogene is designed to help a person's immune system attack their specific cancer. The goal of this study is to learn if people who receive intismeran autogene with pembrolizumab and chemotherapy live longer overall and without the cancer growing or spreading compared to people who receive placebo with pembrolizumab and chemotherapy. A placebo looks like the study treatment but has no study treatment in it. Using a placebo helps researchers better understand the effects of the study treatment.

Outcome Measures

Primary Outcomes (2)

  • Progression Free Survival (PFS)

    PFS is defined as the time from randomization to the first documented progressive disease (PD) or death due to any cause, whichever occurs first as assessed by Response Criteria in Solid Tumors Version 1.1 (RECIST 1.1). PD is defined as ≥20% increase in the sum of diameters of target lesions. In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of ≥5 mm. The appearance of one or more new lesions is also considered PD. PFS as assessed by blinded independent central review (BICR) will be presented.

    Up to ~32 months

  • Overall Survival (OS)

    OS, defined as the time from randomization to death due to any cause. OS will be presented.

    Up to ~42 months

Secondary Outcomes (4)

  • Overall Response Rate (ORR)

    Up to ~26 months

  • Duration of Response (DOR)

    Up to ~42 months

  • Number of Participants who Experience an Adverse Event (AE)

    Up to ~42 months

  • Number of Participants who Discontinue Study Intervention Due to an AE

    Up to ~24 months

Study Arms (2)

Intismeran Autogene + Pembrolizumab + Chemo

EXPERIMENTAL

Induction phase: Participants receive pembrolizumab 400 mg intravenous (IV) infusion on Day 1 of a six week cycle plus a platinum doublet chemotherapy regimen (carboplatin area under the curve (AUC) 6 or 5 mg/mL/min IV infusion every 3 weeks (Q3W) × 2 doses combined either with paclitaxel 200 or 175 mg/m\^2 IV infusion Q3W × 2 doses, OR with nab paclitaxel 100 mg/m\^2 IV infusion weekly × 6 doses). Intismeran Autogene 1 mg intramuscular (IM) injection is administered on Days 1 and 22 of Cycle 2 Induction (Q3W) for up to 2 doses. Maintenance phase: Participants receive pembrolizumab 400 mg IV infusion on Day 1 every 6 weeks (Q6W) for up to 15 doses. Intismeran Autogene 1 mg IM injection is administered on Days 1 and 22 (Q3W) for up to 7 doses during maintenance.
