2026년 8월 6일 업데이트: Washington University School of Medicine
A Phase Ib Study Evaluating the Safety and Tolerability of Sipuleucel-T (Sip-T) in Combination With N-803 in Patients With Metastatic Androgen Pathway Modulation Resistant (mAPMR) Prostate Cancer
This phase Ib single-center open-label de-escalation study uses a modified 3+3 design to determine the safety, tolerability, and recommended phase II dose (RP2D) of the combination of standard of care Sip-T and N-803 in patients with metastatic androgen pathway modulation resistant (mAPMR) prostate cancer.
Patients will receive treatment for up to 8 weeks.
