A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the safety, tolerability, and anti-cancer effects of HSK39775 in patients diagnosed with advanced solid tumors. Participants must be at least 18 years old and have tumors that have either failed standard treatments or for which no standard therapy is available. The study will involve administering HSK39775 as a monotherapy to assess its efficacy and safety profile in this patient population.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for patients with advanced solid tumors who have limited treatment choices.

How similar studies have gone: While there have been studies on similar treatments, the specific approach with HSK39775 is novel and has not been extensively tested.
