Ruxolitinib and Enzalutamide for the Treatment of Metastatic Castration-Resistant Prostate Cancer
Is NCT06616155 recruiting? Yes, currently enrolling (May 2026). This Phase 1/2 trial studies multiple treatments including Enzalutamide and Ruxolitinib for castration-resistant prostate carcinoma.
Treatment: Enzalutamide · Ruxolitinib — This phase I/II tests the safety, side effects and best dose of ruxolitinib in combination with enzalutamide and how well it works in treating patients with prostate cancer that remains despite blocking hormone production (castration-resistant) and that has spread from where it first started to other places in the body (metastatic). Ruxolitinib, a kinase inhibitor, slows down the growth of the tumor by blocking the proteins, JAK1 and JAK2, tumors use to grow. Enzalutamide, an androgen receptor inhibitor, works by blocking the effects of androgen (a male reproductive hormone). This may help stop the growth and spread of tumor cells that need testosterone to grow. Giving ruxolitinib in combination with enzalutamide may be safe, tolerable, and/or effective in treating metastatic castration-resistant prostate cancer.
