Frequently asked questions about INCA33890

What is INCA33890?

INCA33890 is an investigational small molecule in clinical development by Incyte Corporation for oncology. It is being studied in colorectal cancer, resectable locally advanced head and neck squamous cell carcinoma, and advanced or metastatic solid tumors. It is designed as a bispecific agent directed at TGFβR2 and PD-1, and it is not yet approved for any use.

What does INCA33890 target?

INCA33890 targets TGFβR2 and PD-1 as a bispecific small molecule, engaging both the TGF-beta receptor 2 pathway and the PD-1 immune checkpoint. This dual targeting is intended to combine checkpoint blockade with TGF-beta pathway inhibition in a single agent, and it is being evaluated in biomarker-selected patient populations.

Who is developing INCA33890?

INCA33890 is being developed by Incyte Corporation, which trades on Nasdaq under the ticker INCY. Incyte is the sponsor of the clinical program, which includes a Phase 3 trial in metastatic microsatellite stable colorectal cancer and earlier-phase studies in head and neck cancer and solid tumors.

What phase is INCA33890 in?

INCA33890 is in Phase 3 development. Its most advanced trial is a Phase 3 study in first-line metastatic microsatellite stable colorectal cancer, and additional Phase 2 studies are planned in circulating tumor DNA-positive colorectal cancer and resectable locally advanced head and neck squamous cell carcinoma. INCA33890 remains investigational and is not approved.

What clinical trials is INCA33890 in?

INCA33890 is being studied in four registered trials. NCT07284849 is a recruiting Phase 3 trial adding INCA33890 to standard chemotherapy and bevacizumab in first-line metastatic microsatellite stable colorectal cancer. NCT05836324 is a recruiting Phase 1 solid tumor study. NCT07823322 and NCT07876414 are Phase 2 trials not yet recruiting.

Is INCA33890 approved by the FDA?

No, INCA33890 is not approved by the FDA. It is an investigational agent still in clinical development, with its lead program in Phase 3 testing in metastatic microsatellite stable colorectal cancer. Safety and efficacy have not been established, and access is currently limited to participation in its clinical trials.
