Study Endpoints

Primary Endpoints

Dose Escalation and Enrichment: Percentage of Participants with Dose-limiting Toxicity (DLTs)
Up to 5 years

Any of the prespecified AEs that are attributable to the study treatment, occurring in the DLT observation period are considered DLTs, excluding toxicities clearly due to underlying disease or extraneous causes.

Dose Escalation, Enrichment and Expansion: Incidence and Severity of Treatment-emergent Adverse Events (TEAEs) and Serious AEs
Up to 5 years

An adverse event (AE) is any untoward medical occurrence in a participant who received study medication without regard to possibility of causal relationship to it.

Dose Escalation and Enrichment: Maximum Tolerated Dose (MTD) of BLU-924
Up to 5 years
Dose Escalation and Enrichment: Recommended Dose for Expansion (RDFE) of BLU-924
Up to 5 years
Dose Expansion: Overall Response Rate (ORR)
Up to 5 years

Secondary Endpoints

Dose Escalation and Enrichment: Overall Response Rate (ORR)
Up to 5 years
Dose Escalation, Enrichment, and Expansion: Duration of Response (DOR)
Up to 5 years
Dose Escalation, Enrichment, and Expansion: Disease Control Rate (DCR)
Up to 5 years

Treatment Arms

ArmTypeDescription
Monotherapy Part: BLU-924 Dose Escalation, Dose Enrichment, and Dose ExpansionEXPERIMENTALParticipants will receive BLU-924 oral tablet, once daily as monotherapy during Dose Escalation followed by Dose Enrichment. During Dose Enrichment, participants with PDAC, NSCLC or CRC will receive BLU-924 at selected dose levels below the current escalation dose or, if Dose Escalation is complete, below the MTD. During Dose Expansion, participants will receive RDFE of BLU-924 oral tablet, once daily as monotherapy determined during escalation monotherapy part. Dose Expansion may be initiated to further assess the safety, antitumor activity, PK, and pharmacodynamics of BLU-924 at RDFE in indication-specific cohorts (PDAC, NSCLC, or CRC) harboring a KRAS mutation.

Frequently asked questions about BLU-924

What is BLU-924 used for?

BLU-924 is an investigational small molecule being studied for the treatment of advanced solid tumors that harbor KRAS mutations. The Phase 1 trial enrolls adults with advanced solid tumors, including non-small cell lung cancer, colorectal neoplasms, and pancreatic ductal adenocarcinoma. It is not approved for any use and remains in clinical development.

Who is developing BLU-924?

BLU-924 is being developed by Sanofi, which trades on the New York Stock Exchange under the ticker SNY. Sanofi is running the first-in-human study of the compound, also identified as SAR449336, in patients with KRAS-mutant advanced solid tumors.

What phase is BLU-924 in?

BLU-924 is in Phase 1 development. The single trial of the program is a first-in-human, open-label, uncontrolled study that is currently recruiting participants. No Phase 2 or Phase 3 studies of BLU-924 have been initiated, and the drug has not been approved by the FDA.

What clinical trial is BLU-924 in?

BLU-924 is being evaluated in the trial NCT07629960, titled A First-in-Human Trial of BLU-924 (SAR449336) in Advanced Solid Tumors Harboring KRAS Mutations. The study is recruiting up to 265 adults aged 18 and older across sites in the United States and Spain, and it is not randomized or blinded.

Is BLU-924 the same as SAR449336?

Yes, BLU-924 is also known as SAR449336. The two names refer to the same investigational small molecule, and the first-in-human oncology trial lists both identifiers in its title. Sanofi is the developer behind both designations.

Is BLU-924 biomarker selected?

Yes, BLU-924 is being studied in a biomarker-selected population. The Phase 1 trial enrolls only patients whose advanced solid tumors harbor KRAS mutations, spanning non-small cell lung cancer, colorectal neoplasms, and pancreatic ductal adenocarcinoma. This enrichment strategy focuses the study on tumors with a defined molecular alteration.
