What this trial studies

This Phase I clinical trial aims to assess the safety, pharmacokinetics, and preliminary anti-tumor activity of RO7566802, both as a standalone treatment and in combination with atezolizumab, in patients with locally advanced, recurrent, or metastatic solid tumors. The study will be conducted in two stages: a dose escalation phase to determine the optimal dosing and an expansion phase to further evaluate the treatment's effects. Participants must have tumors that have progressed after standard therapies or for whom such therapies are not suitable.

Who should consider this trial

Good fit: Ideal candidates include individuals with locally advanced or metastatic solid tumors that have not responded to standard treatments.

Not a fit: Patients currently receiving other anti-cancer therapies or those with active infections like hepatitis or HIV 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 that are difficult to treat.

How similar studies have performed: Other studies have shown promise with similar immunotherapy approaches, suggesting potential for success in this trial.
