NCT ID NCT07480681

First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This early-stage trial tests a new oral drug called HLX97 in 138 people with advanced solid tumors (breast, prostate, or lung cancer) that have stopped responding to standard treatments. The main goals are to check safety, find the right dose, and see if the drug can slow tumor growth. Some participants may also receive a second drug called fulvestrant.

What this could mean

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

Active substance
HLX97 (a KAT6A/B inhibitor taken as a pill)
What this could lead to
If this trial succeeds, it could point toward a new treatment option for advanced solid tumors like breast, prostate, or lung cancer.
What could go wrong
This is an early Phase 1 trial with only 138 participants, so it is too soon to know if HLX97 is safe or effective. The drug may cause side effects or fail to shrink tumors.
