18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  1. Be willing and able to provide written informed consent/assent for the trial.
  2. Be ≥ 18 years of age on day of signing informed consent.
  3. Patients must have received 1 line of prior systemic therapy for metastatic or resectable disease (i.e. patients may have received adjuvant gemcitabine and then later platin-based therapy for recurrent metastatic disease)

  6. Be willing to provide tissue from a newly obtained core or excisional biopsy of a tumor lesion. Newly obtained is defined as a specimen obtained up to 6 weeks (42 days) prior to initiation of treatment on Day 1. Subjects for whom newly obtained samples cannot be provided (e.g. inaccessible or subject safety concern) may submit an archived specimen only upon agreement from the sponsor-investigator. Subjects from whom a biopsy is not medically possible or safe may be enrolled on the study upon agreement from the principal investigator.

  9. Female subject of childbearing potential should have a negative urine or 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.
  10. Female subjects of childbearing potential should 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 (Reference Section in Appendix 3). Subjects of childbearing potential are those who have not been surgically sterilized or have not been free from menses for > 1 year.
  11. Male subjects should 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.

Exclusion Criteria:

  1. A history of anaphylaxis to olaparib
  2. Is currently participating and receiving study therapy or has participated in a study of an investigational agent and received study therapy or used an investigational device within 4 weeks of the first dose of treatment.
  3. A woman of childbearing potential (WOCBP) who has a positive urine pregnancy test within 72 hours prior to 1st dose of treatment (see Appendix 3). If the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required.

  7. Has had prior chemotherapy, targeted small molecule therapy, or radiation therapy within 2 weeks prior to study Day 1 or who has not recovered (i.e., ≤ Grade 1 or at baseline) from adverse events due to a previously administered agent.

    NOTE: Subjects with ≤ Grade 2 neuropathy are an exception to this criterion and may qualify for the study.

    NOTE: If subject received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy.

  8. Has a known additional malignancy that is progressing or requires active treatment. Exceptions include basal cell carcinoma of the skin or squamous cell carcinoma of the skin that has undergone potentially curative therapy or in situ cervical cancer.

Subjects with previously treated brain metastases may participate provided they are stable (without evidence of progression by imaging for at least four weeks prior to the first dose of trial treatment and any neurologic symptoms have returned to baseline), have no evidence of new or enlarging brain metastases, and are not using steroids for at least 7 days prior to trial treatment. This exception does not include carcinomatous meningitis, which is excluded regardless of clinical stability.
  10. Has active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids, or immunosuppressive drugs). Replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment.
  11. Has known history of, or any evidence of active, non-infectious pneumonitis.
  12. Has an active infection requiring systemic therapy.
  13. 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 site investigator.
  14. Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.
  15. Is pregnant or breastfeeding, or expecting to conceive or father children within the projected duration of the trial, starting with the pre-screening or screening visit through 120 days after the last dose of trial treatment.
  16. Has received prior therapy with an anti-PD-1, anti-PD-L1, or anti-PD-L2 agent.
  17. Has a diagnosis of immunodeficiency or is receiving chronic systemic steroid therapy (in dosing exceeding 10 mg daily of prednisone equivalent) or any other form of immunosuppressive therapy within 7 days prior to the first dose of study drug.
  18. Has known active Hepatitis B without HBV treatment (HBV infection with ongoing HBV treatment is allowed); chronic Hepatitis C infection is allowed. Any patient receiving treatment for HCV should wait at least 14 days after completion of HCV treatment before beginning study treatment. No patient should receive HCV treatment while receiving study treatment. Note: no testing for Hepatitis B and Hepatitis C is required unless mandated by local health authority.
  19. Has received a live vaccine within 30 days prior to the first dose of study drug. Examples of live vaccines include, but are not limited to, the following: measles, mumps, rubella, varicella/zoster (chicken pox), yellow fever, rabies, Bacillus Calmette-Guérin (BCG), and typhoid vaccine. Seasonal influenza vaccines for injection are generally killed virus vaccines and are allowed; however, intranasal influenza vaccines (e.g., FluMist®) are live attenuated vaccines and are not allowed.

5. Study Description

Brief Summary
The investigators propose an open label, one-arm study to assess the safety and efficacy of olaparib and pembrolizumab in patients with cholangiocarcinoma who have progressed on or cannot tolerate gemcitabine-based therapy.
Detailed Description
The primary objective of the study is to assess the ORR of patients with advanced cholangiocarcinoma receiving a combination of pembrolizumab and olaparib. It is hypothesized that the addition of olaparib will improve the response rate of second line systemic therapy from 17.5% to 35% in patients with advanced cholangiocarcinoma. The study is designed to enroll 33 subjects (for 85% power) with advanced stage cholangiocarcinoma to test the hypothesis that the combination of olaparib and pembrolizumab will increase the ORR in comparison with the ORR from second line systemic chemotherapy (historical control) in this patient population. As the primary study endpoint, which is also being used to determine the sample size of the study, the investigators propose that the combination of olaparib and pembrolizumab will increase the ORR to 35% from 17.5% (achieved with systemic cytotoxic chemotherapy including mFOLFOX-historical control). To allow a 10% patient drop off rate, the investigators expect to enroll a total of 36 subjects into this study. In addition, as secondary study endpoints the investigators expect to see an increase in the PFS and OS of patients receiving combination therapy compared to cytotoxic chemotherapy. In this study, the investigators propose the collection of three biopsies-one at baseline prior to the start of treatment, one at the beginning of week 4, three weeks after the administration of combination olaparib and pembrolizumab, and one at the time of cancer progression-for the elucidation of exploratory study endpoints. Patients will have a CT or MRI scan at the beginning of treatment and then every 6 weeks thereafter for the first six months of study treatment administration, then every 9 weeks for up to 12 months after the start of treatment, followed by every 12 weeks up to 24 months on study. All patients will continue to receive olaparib and pembrolizumab combination treatment as tolerated unless unacceptable toxicities or cancer progression occur, at which time therapy will cease. In the absence of any problems, the planned study duration is 20-36 months.
