Brief Summary

This study is being done to test the safety and effectiveness of the combination of intravenous (IV) romidepsin and/or oral 5-azacitidine with IV MK-3475 in people with microsatellite stable (MSS) advanced colorectal cancer.

Detailed Description

This study is being done to test the safety and effectiveness of the combination of intravenous (IV) romidepsin and/or oral CC-486 with IV MK-3475 in people with microsatellite stable advanced colorectal cancer.

People with advanced colorectal tumors that are microsatellite stable (MSS) may join this study. Tumors that are MSS positive are not deficient in repair of DNA.

This is a pilot study that will look at different ways of making MSS colorectal tumors sensitive to MK-3475 by giving 14 or 21 days of an epigenetic agent (oral CC-486 and/or romidepsin).

Participants will be randomly assigned (by chance, like drawing numbers from a hat) to one of three study drug combinations:

A. Oral CC-486 taken daily for 21 days (and later shortened to 14 days if there are side effects) and IV MK-3475 given every 2 weeks.

B. IV romidepsin given once weekly for 3 weeks and IV MK-3475 given every 2 weeks C. Oral CC-486 taken daily for 21 days (and later shortened to 14 days if there side effects) and IV romidepsin given every 2 weeks and IV MK-3475 given every 2 weeks.

Each arm is repeated every 28 days and will continue until the point that the study drug are no longer working. It will not be possible to cross over onto another arm if a participant's disease does not respond to the study drugs.

In this study investigators are looking for the following information:

• What effects, good and/or bad, the combination of oral CC-486 and/or romidepsin in combination with MK-3475 has on participants' cancer; and
• If the genetic and chemical make-up of participants' blood and tumor cells play a role in a response to oral CC-486 and/or romidepsin in combination with MK-3475.

3. Be 18 years of age on day of signing informed consent

4. Have measurable disease

5. Have biopsiable disease. If biopsy is attempted and unsuccessful (the patient undergoes an invasive procedure), the patient may still be treated

6. Have a performance status of 0 or 1 on the ECOG Performance Scale at study entry

7. Demonstrate adequate organ function

8. Female subject of childbearing potential must have a negative urine or serum pregnancy test within 72 hours prior to receiving the first dose of study medication

9. Female subjects 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

10. Male subjects must agree to use an adequate method of contraception starting with the first dose of study therapy through 120 days after the last dose of study therapy

11. In patients with liver metastases, there should be <50% involvement of the liver.

12. Patients must have had < 3 prior therapies in the metastatic setting.

Exclusion Criteria

1. Patients whose tumors have progressed at the first restaging during first line therapy

2. Is currently participating in or has participated in a study of an investigational agent or using an investigational device within 4 weeks of the first dose of treatment

3. Has a diagnosis of immunodeficiency or is receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of trial treatment

4. Has had a prior monoclonal antibody within 4 weeks prior to study Day 1 or who has not recovered from adverse events due to agents administered more than 4 weeks earlier

5. Has had prior chemotherapy, targeted small molecule therapy, or radiation therapy within 4 weeks (6 weeks for nitrosureas or mitomycin C) prior to study Day 1 or who has not recovered from adverse events due to a previously administered agent

6. Has a known additional malignancy that is progressing or requires active treatment

7. Has known central nervous system (CNS) metastases and/or carcinomatous meningitis

8. Has an active autoimmune disease requiring systemic treatment within the past 3 months or a documented history of clinically severe autoimmune disease, or a syndrome that requires systemic steroids or immunosuppressive agents.

9. Has evidence of interstitial lung disease or active, non-infectious pneumonitis.

11. Any clinical or radiological ascites or pleural effusions

12. Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject's participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator

13. Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial
