Testing the Effect of M1774 on Hard-to-Treat Refractory SPOP-mutant Prostate Cancer (NCT05828082)

A Phase 2 Study of M1774 in Refractory SPOP-Mutant Prostate Cancer

🔵 Active, Not Recruiting Phase2 💊 Investigational Drug / Biologic Sponsor: National Cancer Institute (NCI)

🩺 Plain-English Summary (8th-Grade Level)

This phase II trial tests how well M1774 works in treating patients with prostate cancer that does not respond to treatment (refractory) and that has a mutation in the gene responsible for making the speckle type BTB/POZ protein (SPOP). M1774 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving M1774 may be able to shrink or stabilize refractory SPOP-mutant prostate cancer.

Who can join: To join this study, participants generally need to meet the listed inclusion criteria (23 items) and avoid the listed exclusions (8 items).

Location: Mayo Clinic Hospital in Arizona — Phoenix, Arizona
