A first in human study to evaluate the safety, tolerability, pharmacokinetics, and antitumor activity of BLU-924 / SAR449336, a pan-KRAS inhibitor, in participants with advanced Pancreatic Cancer, Non-Small Cell Lung Cancer, or Colorectal Cancer harboring KRAS mutations.

This is an open-label, multi-center, Phase 1/2 study designed to evaluate the safety, tolerability, pharmacokinetics (PK), and efficacy of BLU-924, a pan-KRAS inhibitor, in participants with metastatic KRAS mutant pancreatic ductal adenocarcinoma (PDAC), non-small cell lung cancer (NSCLC), or colorectal cancer (CRC). The monotherapy part of the study includes Dose Escalation, Dose Enrichment, and Dose Expansion. Participants enrolled during Dose Escalation and Dose Enrichment will be evaluated for dose limiting toxicities (DLTs) to determine the MTD. Participants enrolled into disease-specific Enrichment cohorts will enable a more robust characterization of safety, PK, pharmacodynamics, and preliminary clinical activity. Enrolment into Dose Expansion will follow the identification of at least 1 recommended dose for expansion (RDFE) based on data from the Dose Escalation and Dose Enrichment. No combination arm is active at this time.

Inclusion Criteria:

1. Pathologically confirmed diagnosis of metastatic Kirsten rat sarcoma viral oncogene homolog (KRAS)-mutant pancreatic ductal adenocarcinoma (PDAC), non-small cell lung cancer (NSCLC), or colorectal cancer (CRC) with evidence of a single KRAS G12C, G12D, G12V, G12A, G12S, or G13D mutation in tumor tissue or circulating tumor deoxyribonucleic acid (ctDNA).
2. Measurable disease by Response Evaluation Criteria in Solid Tumors (RECIST) v1.1.
3. Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0-1.
4. Patients must have received all standard therapies for their cancer type in the metastatic setting, unless they are unable to receive such therapies due to clinical characteristics, comorbidities, or other medically justified reasons.

Exclusion Criteria:

1. History of additional malignancy within the last 2 years, with some exceptions as specified in the protocol.
2. Active brain metastases (participants with asymptomatic brain metastases may be eligible).
3. Have received prior targeted treatment(s) against KRAS, including pan-KRAS inhibitors, multi-RAS inhibitors, mutant-selective KRAS inhibitors, and RAS or KRAS degraders.
4. Active or uncontrolled systemic infection, such as tuberculosis, Hepatitis B virus (HBV), Hepatitis C virus (HCV), or Human immunodeficiency virus (HIV).
