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

Summary

This early-phase trial is testing an experimental oral drug called RGT-490 in about 63 adults with advanced solid tumors (including certain breast, ovarian, and endometrial cancers) that have a PIK3CA gene mutation and have stopped responding to standard treatments. The main goals are to check the drug's safety, find the right dose, and see if it can shrink tumors.

What this could mean

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

Active substance

RGT-490 (oral tablet)

What this could lead to

If successful, this could point toward a new treatment option for people with certain hard-to-treat cancers that have a PIK3CA mutation.

What could go wrong

This is a very early (Phase 1) study with only 63 participants, so it is primarily testing safety and dosing. The drug may not shrink tumors or may cause side effects.
