Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Treatment: Drugs - RO7296682
Treatment: Drugs - Atezolizumab

Experimental: Part I - Dose-Escalation: Mixed solid tumors participants will receive ascending doses of RO7296682 with a fixed dose of Atezolizumab, every three weeks (Q3W) until either the Maximum Tolerated Dose (MTD)/Recommended Phase 2 Dose (RP2D) is defined.

Experimental: Part II - Dose-Expansion: Will start once MTD/RP2D dose of RO7296682 in combination with Atezolizumab is defined in Part I. Participants with selected tumor types will receive a fixed dose of RO7296682 in combination with Atezolizumab.

Experimental: Part III (Exploratory) - Dose-Expansion: Will start once MTD/RP2D dose of RO7296682 in combination with Atezolizumab is defined in Part I and if clinical activity is seen in this trial or in the single agent study (WP41188). Participants with selected tumor types will receive a fixed dose of RO7296682 in combination with Atezolizumab at the dosing regimen established in Part I.

RO7296682 will be administered as per the schedules specified in the respective arms.

Treatment: Drugs: Atezolizumab
