Safety and Efficacy of BMS-986504 in Unresectable Malignant Peripheral Nerve Sheath Tumor

A Phase II Trial to Assess the Safety and Efficacy of BMS-986504 in Unresectable Malignant Peripheral Nerve Sheath Tumor Patients With Homozygous MTAP Deletion

Sponsor

Ankit Mangla, MD

Enrollment

17 participants

Start Date

Aug 1, 2026

Study Type

INTERVENTIONAL

Conditions

Malignant Peripheral Nerve Sheath Tumors MPNST

Summary

People who have a cancer called MPNST, or Malignant Peripheral Nerve Sheath Tumor, may be eligible for this study. The purpose of this study is to see if a new medicine called BMS-986504 may work better than other available medicines for people with MPNST. Methylthioadenosine Phosphorylase (MTAP) loss is a gene mutation that some people have. MTAP loss seems to increase the chance that BMS-986504 can kill MPNST cancer cells. People who are missing MTAP from their tumor may be able to enroll in this study. Treating MPNST based on MTAP loss is considered experimental and is not approved by the US Food and Drug Administration (FDA) for determining whether BMS-98650 will be active against cancer. The purpose of this study is to evaluate the safety and effectiveness of BMS-986504 in participants with MPNST.

Eligibility

Interventions

DRUGBMS-986504

Participants will receive 600 milligrams (mg) of BMS-986504 taken orally (by mouth) on Days 1-28 of each 28-day cycle. Treatment will continue until disease progression, unacceptable toxicity, or withdrawal of consent (up to 2 years). Participants who experience dose-limiting toxicity can be transitioned to 400 mg daily, then 200 mg daily of BMS-986504, or taken off the clinical trial. Nine participants will be enrolled in stage 1. If ≥ 1 participant demonstrates a complete or partial response in stage 1, the trial will proceed to stage 2, where an additional eight participants will be enrolled. If there are no responses or significant safety concerns arise, the trial will be halted.
