Intervention model description: Open-Label, Non-Randomization Phase 2 clinical trial with Safety Run-In (3 parts): Part 1 in 20 newly diagnosed patients who have Stage II-III breast cancer, with the primary cancer in place. These patients have not received prior therapy and intend to undergo surgery after completion of investigational neoadjuvant therapy. Parts 2 and 3 in 20 PRROC and gastric cancer patients, respectively. Enrollment of patients in each of the 3 parts will begin with 3 patients. If no dose-limiting toxicities (DLTs, defined as toxicity ≥Grade 3) are observed during the first cycle, enrollment can continue for the remaining 17 patients. If 1 of the first 3 patients experiences a DLT, the enrollment will be expanded to a total of 6 subjects. If no more than 1 of 6 subjects experiences a DLT, enrollment can continue for the remaining 14 patients. If 2 or more of the first 2-6 subjects experience a DLT, enrollment may be paused and the study data will be reviewed.
Primary purpose: TREATMENT

Brief summary: Safety and tolerability of combination of Nivolumab and Ipilimumab will be studied in patients with 3 different types of cancers in 3 parts of the study, as shown below:

Part 1 - Neoadjuvant Therapy of Breast Cancer;

Part 2 - Therapy of Ovarian Cancer; and

Part 3 - Therapy of Gastric Cancer.

Detailed description: Open-Label, Non-Randomization and Safety Run-In: Part 1 of the study is a Phase 2 clinical trial in 20 newly diagnosed patients who have Stage II-III breast cancer, with the primary cancer in place. Parts 2 and 3 of the Study are Phase 2 clinical trials in 20 platinum resistant refractory ovarian cancer (PRROC) and gastric cancer patients, respectively.

Also in all Parts 1, 2 and 3 of the study, there will be a safety run-in involving 3-6 patients. Specifically, the enrollment of patients in each of the 3 parts of the study will begin with 3 patients. If no dose-limiting toxicities (DLTs, defined as toxicity ≥Grade 3) are observed in the first 3 patients during the first cycle, enrollment can continue for the remaining 17 patients. If 1 of the first 3 patients experiences a DLT, the enrollment will be expanded to a total of 6 subjects. If no more than 1 of 6 subjects experiences a DLT, enrollment can continue for the remaining 14 patients. If 2 or more of the first 2-6 subjects experience a DLT, enrollment may be paused. The study data will be reviewed to determine whether alternate dose levels or treatment schedules should be evaluated.

Eligibility criteria: Inclusion Criteria: Patients must meet all inclusion criteria before enrollment:
