Custom-Made vaccine takes on ovarian cancer

NCT ID NCT03839524

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This Phase 1 trial tested a personalized immunotherapy called TG4050 in 64 women with advanced ovarian, fallopian tube, or peritoneal cancer who had completed standard chemotherapy and were in complete remission. The treatment is made from each patient's unique tumor mutations and given as injections to help the immune system recognize and attack any remaining cancer cells. The main goal was to check safety and tolerability, with some early looks at whether it might help prevent recurrence.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

TG4050 (a personalized cancer vaccine made from the patient's own tumor mutations)

What this could lead to

If successful, this could point toward a new way to keep ovarian cancer from coming back after standard treatment.

What could go wrong

This is an early Phase 1 trial with only 64 participants, so it is mainly checking safety, not yet proven to work. The treatment is personalized and complex, which may limit how widely it can be used.
