What this trial studies

This is a multicenter, open-label, uncontrolled phase I study aimed at evaluating the tolerability, safety, pharmacokinetics, and efficacy of ONO-4538HSC administered subcutaneously to participants with advanced or metastatic solid tumors. The study includes a tolerability confirmation part to determine the recommended dose for Japanese participants by assessing dose-limiting toxicities (DLTs), and an expansion part to further evaluate safety and pharmacokinetics while exploring efficacy. The study targets patients who are refractory or intolerant to standard therapies or for whom no standard therapies are available.

Who should consider this trial

Good fit: Ideal candidates include patients with advanced or metastatic solid tumors who have an ECOG performance status of 0 to 1 and a life expectancy of at least 3 months.

Not a fit: Patients with severe complications or a history of severe hypersensitivity to any antibody product may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option for patients with advanced or metastatic solid tumors who have limited alternatives.

How similar studies have performed: Other studies have shown success with similar approaches in treating advanced solid tumors, indicating potential for this novel treatment.
