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.
| Arm | Type | Interventions | Description |
|---|---|---|---|
| Group 1 - Escalation Dose: RO6870810 + Atezolizumab | Experimental | Drug: Atezolizumab; Drug: RO6870810 | Participants will be administered escalating doses of RO6870810 (0.3 milligram per kilogram \[mg/kg\], 0.45 mg/kg, and 0.65 mg/kg) subcutaneously (SC) once daily (QD) along with fixed dose of atezolizumab 1200 mg intravenously (IV) on Day 1 of each cycle (21 day cycles), every 3 weeks. RO6870810 will be given during the first 14 days. |
| Group 2 - Sequential Dose: RO6870810 + Atezolizumab | Experimental | Drug: Atezolizumab; Drug: RO6870810 | Participants will be administered RO6870810 monotherapy (starting dose 0.30 mg/kg) during the first 14 days of 21-day Run-in period. Following the Run-in period, participants will continue to receive RO6870810 at the same dose in combination with fixed dose of atezolizumab 1200 mg IV every 3 weeks in 21-day cycles. |
| Group 3 - Expansion in TNBC Group: RO6870810 + Atezolizumab | Experimental | Drug: Atezolizumab; Drug: RO6870810 | Participants will be administered dose of RO6870810 established in Group 1 (either 0.3 mg/kg, 0.45 mg/kg, or 0.65 mg/kg) SC QD along with fixed dose of atezolizumab 1200 mg IV on Day 1 of each cycle (21 day cycles), every 3 weeks. RO6870810 will be given during the first 14 days. |
| Group 4 - Expansion in OC Group: RO6870810 + Atezolizumab | Experimental | Drug: Atezolizumab; Drug: RO6870810 | Participants will be administered dose of RO6870810 established in Group 1 (either 0.3 mg/kg, 0.45 mg/kg, or 0.65 mg/kg) SC QD along with fixed dose of atezolizumab 1200 mg IV on Day 1 of each cycle (21 day cycles), every 3 weeks. RO6870810 will be given during the first 14 days. |

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 * Measurable disease by RECIST criteria version 1.1 prior to study drug administration * Performance status of 0 or 1 on the eastern Cooperative Oncology Group (ECOG) scale * Life expectancy, in the opinion of the Investigator, of at least 3 months * Disease-free of active second/secondary or prior malignancies for => 2 years with the exception of squamous cell carcinoma of the skin, or carcinoma in situ of the cervix or breast * Willing to provide the protocol specified tumor biopsies * 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: * Minimum of 5 months from the last dose of anti-PD-1, anti-CTLA-4, anti-PD- L1 or CD137 agonist treatment * No history of severe immune-related adverse effects from CD137 agonist, anti-CTLA-4, anti-PD-1 or anti-PD-L1 (NCI CTCAE Grade 3 and 4). Any toxicity related to the therapy must have resolved completely, no residual toxicity as assessed by NCI CTCAE (v4.03) * Agree to use protocol defined methods of contraception - For all participants, the reliability of sexual abstinence must be evaluated in relation to the duration of the clinical study and the preferred and usual lifestyle of the participant. Periodic abstinence (e.g., calendar, ovulation, symptothermal, or post-ovulation methods) and withdrawal are not acceptable methods of contraception Exclusion Criteria: * Participants with history of prior malignancy except solid tumor treated curatively more than 3 years ago without evidence of recurrence * Asymptomatic or symptomatic, untreated, or actively progressing central nervous system (CNS) metastases * History of leptomeningeal disease * Uncontrolled tumor-related pain * Uncontrolled pleural effusion, pericardial effusion, or ascites requiring recurrent drainage procedures.

Any electrocardiogram (ECG) abnormality, including pericarditis, which in the opinion of the Investigator would preclude safe participation in the study. * Active, uncontrolled bacterial, viral, or fungal infections within 7 days of study entry requiring systemic therapy. Participants with active TB infection are excluded from the study. * Known clinically important respiratory impairment * History of major organ transplant * History of an autologous or allogeneic bone marrow transplant * Serious non-malignant disease that could compromise protocol objectives in the opinion of the Investigator and/or the Sponsor * Pregnant or nursing women * Any systemic anticancer therapy within 3 weeks prior to Cycle 1 Day 1 * Any radiation treatment to metastatic site within <= 14 days of Cycle 1 Day 1 * Major surgical procedure, open biopsy, or significant traumatic injury within 30 days prior to Cycle 1 Day 1 or anticipation of need for major surgical procedure during the course of the study * History of severe allergic, anaphylactic, or other hypersensitivity reactions to chimeric, human or humanized antibodies or fusion proteins * Known hypersensitivity or allergy to biopharmaceuticals produced in Chinese hamster ovary cells or any component of the atezolizumab formulation * Active or history of autoimmune disease * History of idiopathic pulmonary fibrosis (including pneumonitis), drug-induced pneumonitis, organizing pneumonia (i.e., bronchiolitis obliterans, cryptogenic organizing pneumonia), or evidence of active pneumonitis on screening chest computed tomography (CT) scan.
