Testing BR101 injection in patients with advanced solid tumors

A Phase Ia Open-label, Dose-escalation Study to Evaluate the Safety, Tolerability, Pharmacokinetics, Immunogenicity, and Antitumor Activity of BR101 Injection, as a Single Agent in Subjects With Advanced Solid Tumors

Phase 1 Interventional BioRay Pharmaceutical Co., Ltd. · NCT06001580

This study is testing a new injection called BR101 to see if it can help people with advanced solid tumors who haven't had success with other treatments.

What this trial studies

This phase I study evaluates the safety and tolerability of BR101, a monotherapy, in patients with advanced solid tumors. Participants will receive single and multiple doses of BR101 to determine the maximum tolerated dose (MTD) and the recommended phase 2 dose (RP2D). Additionally, the study will explore the pharmacokinetics, immunogenicity, and antitumor activity of BR101. The goal is to assess how well this treatment works in patients who have not responded to standard therapies.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with advanced or metastatic solid tumors that are not amenable to surgical resection and have failed or been intolerant to standard treatments.

Not a fit: Patients with early-stage tumors that can be surgically removed or those who have not yet undergone standard treatment may not benefit from this study.

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 performed: While this approach is not widely tested, similar studies of novel therapies in advanced solid tumors have shown promise in the past.
