Brief Summary:
The purpose of this study is to test the efficacy, safety, and tolerability of the combination of chemotherapy treatment, which could be either Cisplatin or carboplatin and etoposide, and the research study drug, Pembrolizumab (also known as MK-3475) in patients with high grade neuroendocrine carcinomas of the gastroenteropancreatic system or lung who are chemotherapy naïve. The chemotherapy treatment you receive will be either Cisplatin or carboplatin and etoposide. the participant's doctor will discuss this choice with you and determined which chemotherapy treatment is best for you.

Condition or disease Intervention/treatment Phase
Neuroendocrine Carcinoma Large Cell Neuroendocrine Carcinoma of the Lung High Grade Neuroendocrine Carcinoma, Any Site Drug: Pembrolizumab Phase 2

Detailed Description:

Combination chemotherapy is the mainstay of treatment for patients with high grade GEPNETs and neuroendocrine carcinomas of the lung.

This study will utilize pembrolizumab, a potent humanized immunoglobulin G4 (IgG4) monoclonal antibody (mAb) with high specificity of binding to the programmed cell death 1 (PD-1) receptor, thus blocks a protective mechanism of cancer cells and thereby allows the immune system to destroy them, in combination with chemotherapy.

Combination chemotherapy and pembrolizumab was recently FDA approved and ongoing trials are utilizing this or similar combination with preliminary data demonstrating a promising safety profile.

Layout table for eligibility information
Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

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. Must have cytologically or histologically proven high grade neuroendocrine carcinoma of the gastroenteropancreatic system or large cell neuroendocrine carcinoma as defined by the 2010 WHO classification.

    a. GEPNETs need to have Ki-67 greater than 55%.

  4. Have metastatic or unresectable disease.
  5. No prior systemic chemotherapy or immunotherapy for metastatic disease allowed.
  6. Concurrent use of somatostatin analogs is allowed for symptom control.
  7. Life expectancy greater than 12 weeks.
  8. Have measurable disease based on RECIST 1.1.
  9. 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/PI.
  10. Have a performance status of 0 - 1 on the ECOG Performance Scale.
  11. Demonstrate adequate organ function. All screening labs should be performed within 10 days of treatment initiation.
  12. 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.
  13. Female subjects of childbearing potential must be willing to use an adequate method of contraception for the course of the study through 120 days after the last dose of study medication.

    Note: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the subject.

  14. Male subjects of childbearing potential 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.

    Note: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the subject.

  15. Willing and able to comply with scheduled visits, treatment plan, laboratory tests, and other trial procedures.

Exclusion Criteria:

  1. 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.
  2. 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.
  3. Has a known history of active TB (Bacillus Tuberculosis)
