Is this trial a fit for you?

Likely a good fit

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

Probably 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.

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

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.

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