Phase I/II Study of the Anti-Programmed Death Ligand-1 Durvalumab Antibody (MEDI4736) in Combination With Olaparib and/or Cediranib for Advanced Solid Tumors and Advanced or Recurrent Ovarian, Triple Negative Breast, Lung, Prostate and Colorectal Can...

Study Overview
=================
Brief Summary
-----------------
Background: - Durvalumab is a drug that may help people s immune systems respond to and kill cancer cells. Olaparib is a drug that may inhibit repairing DNA damage of cancer cells. Cediranib is a drug that may stop the blood vessel growth of cancer cells. This study has two components. In the phase 1 component of the study, researchers want to investigate how well participants tolerate the combination of these drugs in treating advanced solid tumors, and in the phase 2 part of this study, researchers want to study if the combination treatments are effective in ovarian cancer. Objectives: - Phase 2 part of the study: To determine how effective this combination is in treating ovarian cancer. Eligibility: - Phase 2 part of the study: Adults age 18 or older with advanced or recurrent ovarian cancer that has no standard treatment. Design: Participants will be screened with medical history, physical exam, and blood and urine tests. They will have CT or MRI scans. For these, they will lie in a machine that takes pictures of their bodies. Phase 2 part of the study requests the participants to have tumor samples removed. Participants will get Durvalumab through an IV. A small plastic tube will be inserted into a vein. The drug will be given every 4 weeks until disease progression. Participants will take olaparib or cediranib by mouth every day. Every 28 days will be 1 cycle. For cycle 1, participants will have 2 study visits. All other cycles, they will have 1 visit. At these visits, they will repeat the screening procedures. Patients will keep a drug and diarrhea diary. Patients on cediranib will monitor their blood pressure and keep a blood pressure diary. Participants who can become pregnant, or have a partner who can become pregnant, must practice an effective form of birth control. After 12 cycles, participants will have 1-3 months of follow-up.

Detailed Description
-----------------
Background: Disruption of the immune checkpoint PD-1/PD-L1 pathway yielded clinical activity in subsets of advanced solid tumors, such as melanoma and lung cancer. Olaparib (O), a PARP inhibitor (PARPi), has demonstrated single agent activity in recurrent ovarian cancer (OvCa), and subsets of prostate, triple negative breast or lung cancers. Our recent randomized phase 2 study showed that O and cediranib (C), a VEGFR1-3 inhibitor was clinically superior to O alone in platinum-sensitive recurrent OvCa. We hypothesize that increased DNA damage by PARP inhibition and/or reduced angiogenesis by VEGFR inhibition will complement the anti-tumor activity of an immune checkpoint inhibitor, Durvalumab, in recurrent OvCa and other solid tumors. Objectives: Phase I: To determine the recommended phase II dose (RP2D) and the safety of doublet therapies (Durvalumab/olaparib [Durvalumab+O] and Durvalumab/cediranib [Durvalumab+C]) and triplet therapy (Durvalumab+O+C) in patients with advanced solid tumors.

Phase II Correlative studies: Research samples including whole blood, CTCs, cell free DNA and plasma will be obtained at pretreatment, prior to cycle 1 day 15, prior to cycle 3 day 1 and at progression. Mandatory baseline core biopsy and two optional biopsies will be obtained. Patients will be evaluated for toxicity every 4 weeks by CTCAEv4.0, and for response every two cycles (8 weeks) by RECIST 1.1.
