Brief summary

This is a study evaluating the efficacy and safety of calderasib with pembrolizumab as first-line treatment in participants with locally advanced or metastatic non-small cell lung cancer (NSCLC) with identified Kirsten rat sarcoma viral oncogene homolog G12C (KRAS G12C) mutation and programmed cell death ligand 1 (PD-L1) tumor proportion score (TPS) ≥50%. There are two primary study hypotheses: Hypothesis 1: Combination of calderasib and pembrolizumab is superior to placebo plus pembrolizumab with respect to progression free survival (PFS) per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) by blinded independent central review (BICR). Hypothesis 2: Combination of calderasib plus pembrolizumab is superior to placebo plus pembrolizumab with respect to overall survival (OS).

Design outcomes

Primary

MeasureTime frameDescription
Progression-Free Survival (PFS)Up to approximately 42 monthsPFS is defined as the time from randomization until either documented disease progression per Response Criteria in Solid Tumors Version 1.1 (RECIST 1.1) or death due to any cause, whichever occurs first. PFS as determined by blinded independent central review (BICR) will be presented.
Overall Survival (OS)Up to approximately 56 monthsOS is defined as the time from randomization to death due to any cause.

Secondary

MeasureTime frameDescription
Objective Response Rate (ORR)Up to approximately 42 monthsORR is defined as the percentage of participants with Complete Response or Partial Response per RECIST1.1. The percentage of participants who experience CR or PR as assessed by BICR will be presented.
Duration of Response (DOR)Up to approximately 42 monthsFor participants who demonstrate confirmed CR or PR per RECIST 1.1 as assessed by BICR, duration of response is defined as the time from the first documented evidence of CR or PR until disease progression or death due to any cause, whichever occurs first.
Number of Participants Who Experience One or More Adverse Event (AEs)Up to approximately 56 monthsAn AE is any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE. The number of participants who experience an AE will be presented.
Number of Participants Who Discontinue Study Treatment Due to an Adverse Event (AE)Up to approximately 56 monthsAn AE is any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an AE. The number of participants who discontinue study treatment due to an AE will be presented.
