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

Summary

This early-phase trial is testing a combination of two immunotherapy drugs, naptumomab estafenatox and durvalumab, in 120 people with advanced or metastatic solid tumors like pancreatic, ovarian, and lung cancer. The main goal is to find a safe dose and see how the body reacts. Researchers are also checking if the combo can shrink tumors in certain cancers.

Active substance

naptumomab estafenatox and durvalumab (immunotherapy drugs)

What this could lead to

If successful, this could lead to a new combination treatment option for several advanced cancers that are hard to treat.

What could go wrong

This is a very early Phase 1 trial, so safety and the right dose are still being figured out. It may not work for all cancer types, and side effects from the immune system are possible.
