An Investigational Study of BG-75202 Alone and in Combination With Other Agents in Adults With Advanced Solid Tumors

9. november 2026 opdateret af: BeOne Medicines

En fase 1a/1b-studie, der evaluerer sikkerheden, tolerabiliteten, farmakokinetikken, farmakodynamikken og den foreløbige antikanceraktivitet af BG-75202, både alene og i kombination med andre midler, hos patienter med fremskreden solid tumor

The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics, and preliminary antitumor activity of BG-75202 (KAT6A/B inhibitor) alone and in combination with other therapies in participants with breast cancer and other advanced solid tumors.

Detaljeret beskrivelse

This study will enroll participants with advanced or metastatic solid tumors, including breast cancer. Breast cancer is one of the most common cancers in women.

BG-75202 is an experimental drug that blocks proteins called KAT6A and 6B. These proteins are believed to help tumor growth in a number of cancers including certain types of breast cancer and other solid tumors. By blocking KAT6A and 6B, BG-75202 may be able to slow down or stop the growth of tumor cells.

This study consists of 2 parts, one called dose escalation and safety expansion and the other called dose optimization and dose expansion.

During the dose escalation and safety expansion part, the study doctors will test different doses of the study drug. This part of the study will evaluate BG-75202 alone (monotherapy) and combined with another drug (combination therapy).

During the dose optimization and dose expansion part, the study doctors will test the study drug in a larger number of people using the dose(s) identified from dose escalation and safety expansion. In this part of the study, BG-75202 will be taken with 1 or 2 other drugs.

The study will enroll participants with advanced or metastatic solid tumors at multiple centers worldwide.

The overall time to participate in this study may be up to approximately five years. Participants will make regular visits to the clinic for treatment, health checks, blood tests, and tumor and imaging tests.
