New breast cancer drug candidate BL0175 enters first human safety trial

NCT ID NCT07366632

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This Phase 1 study will test a single injection of BL0175, a new polymer-linked form of the breast cancer drug fulvestrant, in 27 healthy postmenopausal women. The goal is to see if BL0175 is safe and how long it stays in the body compared to standard fulvestrant. This is an early-stage trial that does not involve cancer patients and will not measure whether the drug works against tumors.

What this could mean

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

Active substance

BL0175 (a polymer-linked form of fulvestrant)

What this could lead to

If successful, this early study could pave the way for a longer-lasting version of fulvestrant, potentially reducing injection frequency for breast cancer treatment.

What could go wrong

This is a very early Phase 1 trial with only 27 healthy volunteers, not patients. It only tests safety and drug levels, not whether the drug works against cancer. Many early-stage drugs fail to show benefit later.
