DSP107 plus atezolizumab versus fruquintinib for advanced colorectal cancer

Official title: A Randomized, Open-label, Phase 2b Study to Compare the Efficacy of DSP107 in Combination With Atezolizumab Versus Fruquintinib in Patients With Advanced Microsatellite Stable Colorectal Cancer

Run by Kahr Medical · NCT07235293 · Data updated 2026-11-12

This test will see if giving DSP107 together with atezolizumab works better and is as safe as fruquintinib for adults with advanced microsatellite-stable colorectal cancer who have already tried standard treatments.

Is this trial a fit for you?

Likely a good fit

Adults (≥18) with histologically confirmed inoperable MSS or pMMR colorectal cancer, measurable disease, and progression or intolerance after standard therapies (up to three prior lines) who have not received fruquintinib or regorafenib are the intended candidates.

Probably not a fit

Patients with MSI-high tumors, active autoimmune disease, unresolved grade 2+ toxicities from prior therapy, recent other malignancies, or prior fruquintinib/regorafenib exposure are unlikely to benefit or are ineligible.

What this trial studies

This Phase 2b, randomized, open-label, multicenter study enrolls adults with advanced MSS or pMMR colorectal cancer who have progressed on or are intolerant to standard therapies. Participants are randomized 1:1 to receive DSP107 plus atezolizumab on a 28-day cycle or oral fruquintinib on days 1–21 of each 28-day cycle, with treatment continued until progression or unacceptable toxicity. The trial will measure tumor response by RECIST v1.1, safety and tolerability, and pharmacokinetics, with regular imaging and safety assessments. Enrollment occurs at several U.S. academic centers and excludes prior treatment with fruquintinib or regorafenib.

Why it matters

Potential benefit: If successful, the combination could improve tumor response and extend disease control for people with MSS colorectal cancer who have limited treatment options.

How similar studies have gone: Previous efforts to make checkpoint inhibitors effective in MSS colorectal cancer have shown limited success, so this specific DSP107 plus atezolizumab approach is relatively novel with limited prior proof-of-concept.
