Testing ROSE12 alone and with other cancer treatments for solid tumors

A Phase Ia/Ib Open-label, Dose-escalation Study to Evaluate the Safety and Pharmacokinetics of ROSE12 as a Single Agent and in Combination With Other Anti-tumor Agents in Patients With Locally Advanced or Metastatic Solid Tumors

PHASE1 · Chugai Pharmaceutical · NCT05907980

This study is testing a new cancer treatment called ROSE12, both on its own and with other therapies, to see how safe it is and how well it works for people with advanced solid tumors.

What this trial studies

This Phase I open-label study evaluates the safety and pharmacokinetics of ROSE12, both as a standalone treatment and in combination with other anti-tumor agents, in patients with locally advanced or metastatic solid tumors. The study is structured in three parts: a dose-escalation phase to determine the optimal dosage, a biopsy phase to assess biomarkers, and an expansion phase to further evaluate the treatment's efficacy. Participants will be closely monitored for safety and response to the treatment.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with locally advanced or metastatic solid tumors that have not responded to standard treatments.

Not a fit: Patients with significant cardiovascular or liver disease or those who have experienced severe immune-mediated adverse events from previous cancer therapies may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new treatment option for patients with solid tumors that are resistant to standard therapies.

How similar studies have performed: Other studies have shown promise with similar approaches in targeting solid tumors, suggesting potential for success in this novel treatment strategy.
