Is this trial a fit for you?

Likely a good fit

Adults 18–75 with advanced solid tumors who have progressed on or cannot tolerate standard treatments, have ECOG performance status 0–1, expected survival ≥3 months, adequate organ function, and at least one evaluable/measurable lesion are ideal candidates.

Probably not a fit

Patients outside the 18–75 age range, with ECOG ≥2, inadequate organ function, active pregnancy, or without evaluable/measurable lesions are unlikely to benefit or be eligible.

What this trial studies

This Phase Ia/Ib trial follows a dose-escalation (Phase Ia) then dose-expansion (Phase Ib) design to identify safe dose levels and gather early signs of anti-tumor activity. Participants are adults aged 18–75 with advanced solid tumors, ECOG 0–1, and at least one evaluable or measurable lesion per RECIST 1.1. The study will collect safety, tolerability, pharmacokinetics, and preliminary efficacy data after administering HS387. Enrollment and treatments are conducted at Zhejiang Cancer Hospital in Hangzhou, Zhejiang.

Why it matters

Potential benefit: If successful, HS387 could provide a new treatment option with acceptable safety and measurable anti-tumor activity for patients with advanced solid tumors who have no standard therapies left.

How similar studies have gone: Dose-escalation followed by expansion cohorts is a common early-phase approach and has identified effective regimens for other agents, but HS387 itself is an early-phase investigational agent with unproven clinical benefit.
