First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tested a combination of two drugs—pembrolizumab (an immunotherapy) and cyclophosphamide (a chemotherapy)—in 129 people with advanced sarcomas that had spread or could not be removed by surgery. The goal was to see if the combination could shrink tumors or stop them from growing for at least 6 months. The trial included different types of sarcoma to see which might benefit most.

Active substance

Pembrolizumab (MK3475) and cyclophosphamide

What this could lead to

If successful, this combination could offer a new treatment option for people with advanced sarcomas that are hard to treat.

What could go wrong

This is a phase 2 trial, so results are preliminary. The combination may not work for all sarcoma types and could cause side effects like immune-related reactions.
