Is this trial a fit for you?

Likely a good fit

Ideal candidates include individuals with advanced, recurrent, or metastatic solid tumors that have confirmed RAS mutations and meet specific health criteria.

Probably not a fit

Patients with untreated central nervous system metastases or those with significant gastrointestinal issues 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 study evaluates the safety and tolerability of RO7673396 in patients with advanced solid tumors that have RAS mutations. It consists of two stages: the first stage focuses on determining the recommended doses for further testing, while the second stage assesses the preliminary anti-tumor activity of these doses. Participants will be closely monitored for any adverse effects and the effectiveness of the treatment. The study aims to provide insights into the potential of RO7673396 as a therapeutic option for this patient population.

Why it matters

Potential benefit: If successful, this treatment could offer a new therapeutic option for patients with advanced solid tumors harboring RAS mutations.

How similar studies have gone: While this approach is novel in targeting RAS mutations specifically, similar studies have shown promise in evaluating targeted therapies for solid tumors.
