Brief summary: This research study is studying the combination of Pegylated Liposomal Doxorubicin (PLD) and Pembrolizumab as a possible treatment for Recurrent Ovarian, Fallopian Tube or Peritoneal Cancer that is resistant to platinum therapy.

The following interventions will be used in this study:

* Pegylated liposomal doxorubicin (PLD)
* Pembrolizumab

Detailed description: This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational drug to learn whether the drug works in treating a specific disease. "Investigational" means that the drug is being studied.

The investigators are looking to see if combining the standard therapy, PLD, and the study drug, Pembrolizumab, will be better than PLD alone. Pembrolizumab is a drug called a monoclonal antibody. Pembrolizumab blocks and interferes with a protein called PD-1; PD-1 can help the cancer cell evade the immune system, and thereby blocking PD-1 may help the immune system recognize and kill cancer cells.

This will be the first time this combination will be tested for participants with Ovarian, Fallopian Tube or Peritoneal Cancer. Therefore, a group of 6 participants will be treated in a "safety lead in" portion of the trial. This lead in will determine the safest dose of PLD when given in combination with the study drug Pembrolizumab. These 6 participants will be treated with Pembrolizumab and PLD at the FDA approved dose to see if the combination is well tolerated or too severe. If the combination is well tolerated, 20 additional participants will be added. If the side effects are too severe, the dose of PLD will be lowered.

The FDA (the U.S. Food and Drug Administration) has approved PLD as a treatment option for this disease, but has not approved Pembrolizumab.

Eligibility criteria: Inclusion Criteria:

* Be willing and able to provide written informed consent/assent for the trial.
* Be 18 years of age on day of signing informed consent.
* Have measurable disease based on RECIST 1.1 criteria.
* Have a histologically confirmed diagnosis of epithelial ovarian cancer, fallopian tube or peritoneal cancer. All histologies of epithelial ovarian cancer are eligible except for carcinosarcomas.
* Patients must have had one prior platinum-based chemotherapeutic regimen for management of primary disease containing carboplatin, cisplatin, or another organoplatinum compound. This initial treatment may have included intraperitoneal therapy, consolidation, biologic/targeted (non-cytotoxic) agents (e.g., bevacizumab) or extended therapy administered after surgical or non-surgical assessment.
* Patients must have platinum resistant cancer with a platinum free interval of \< 6 months. Progression after last platinum is based on investigator assessment.
* Patients are allowed to receive, but are not required to receive, up to two additional cytotoxic regimens for management of recurrent or persistent disease, with no more than 1 non-platinum, non-taxane regimen.
* Patients are allowed to receive, but are not required to receive, biologic/targeted (non-cytotoxic) therapy as part of their primary treatment regimen. For the purposes of this study, Poly (ADP-ribose) polymerase (PARP) inhibitors will be considered "cytotoxic." Patients are allowed to receive, but are not required to receive, PARP inhibitors for management of primary or recurrent/persistent disease (either alone or in combination with cytotoxic chemotherapy). Single agent hormonal therapies will not be counted as a line of treatment.
* Have adequate tissue from an archived specimen of ovarian cancer (between 10 to 15 slides of unstained tumor).
* Have a performance status of 0 or 1 on the ECOG Performance Scale (Appendix A).
* Demonstrate adequate organ function as defined in Table 1, all screening labs must be performed within 10 days of treatment initiation.

* Female participants of childbearing potential must have a negative serum pregnancy within 72 hours prior to receiving the first dose of study medication. If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.
* Female participants of childbearing potential must be willing to use 2 methods of birth control or be surgically sterile, or abstain from heterosexual activity for the course of the study through 120 days after the last dose of study medication. Participants of childbearing potential are those who have not been surgically sterilized or have not been free from menses for \> 1 year.
