NCT ID NCT05872347

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

Summary

This Phase 2 trial tests a new oral drug called SPH4336 combined with standard hormone therapy for people with HR-positive, HER2-negative breast cancer that has spread to the brain. The study aims to see if the combination can shrink brain tumors and control the disease. About 52 participants will be enrolled, and the main focus is on how well the treatment works inside the brain.

What this could mean

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

Active substance

SPH4336 (a targeted drug taken orally) combined with endocrine therapy (letrozole, fulvestrant, or exemestane)

What this could lead to

If successful, this could offer a new treatment option for people with HR-positive, HER2-negative breast cancer that has spread to the brain, potentially shrinking or controlling brain tumors.

What could go wrong

This is an early Phase 2 trial with only 52 participants, so results may not apply to everyone. The drug may cause side effects or fail to improve outcomes compared to existing treatments.
