Summary

This phase 2 trial is testing an experimental drug called ubamatamab, alone or combined with other cancer drugs, in 220 people with advanced ovarian, fallopian tube, or primary peritoneal cancer that has stopped responding to platinum-based chemotherapy. The study aims to see how safe and effective these combinations are, and how they affect tumor growth and side effects.

What this could mean

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

Active substance

Ubamatamab (a bispecific antibody that targets cancer cells and immune cells)

What this could lead to

If successful, this could provide a new treatment option for people with ovarian cancer that no longer responds to platinum-based chemotherapy.

What could go wrong

This is a phase 2 trial, so it is still early. The drug may not work as hoped, and side effects like cytokine release syndrome are possible.
