Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is Phase IB, open label, non-randomized study designed to investigate the dose, safety, pharmacokinetics and anti-tumor activity of RO6870810 in combination with a fixed dose of atezolizumab. The study consists of four groups, Group 1 (Dose Escalation Group) and Group 2 (Sequential Dose Group), and Groups 3 and 4 (Expansion Groups), which will further evaluate the safety, pharmacokinetic, pharmacodynamic and preliminary clinical activity in patients with triple negaive breast cancer and/or ovarian cancer.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Groups 1 and 2: Participants with histologically confirmed advanced ovarian cancer or triple negative breast cancer who in the opinion of the Investigator are appropriate for this study
* Group 3: Participants with histologically confirmed TNBC who have received either one or 2 prior systemic treatments for metastatic breast cancer, and who have documented disease progression on or after the most recent treatment
* Group 4: Recurrent ovarian cancer participant who have received no more than two prior lines of platinum therapy in the recurrent setting and have progressed within 9 months from the last platinum containing regimen

* Acceptable hematologic status, liver and renal function
* Groups 1 and 2: Participants who have received prior treatment with CD137 agonists or immune checkpoint blockade therapies, including anti-CTLA-4, anti-PD-1, and anti-PD-L1 therapeutic antibodies, may be enrolled, provided the following requirements are met:
