A Study of Pembrolizumab in Patients With Neuroendocrine Tumors

Completed · Phase 2

Conditions studied: Neuroendocrine Tumors

In brief

The purpose of this research study is to test if pembrolizumab is safe and effective for treating patients with metastatic high-grade neuroendocrine tumors who have failed platinum based chemotherapy.The study drug, pembrolizumab has been FDA approved for treating a type of skin cancer called melanoma and for metastatic non-small cell lung cancer. However, it is not approved for treatment of metastatic high-grade neuroendocrine tumors.

Patients must have normal organ and marrow function
Female participants of childbearing potential must have a negative serum pregnancy within 72 hours prior to receiving the first dose of study medication). They should also 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. Note: Abstinence is acceptable if this is the usual lifestyle and preferred contraception for the subject.

You may not qualify if…

Known active central nervous system (CNS) metastases and/or carcinomatous meningitis. 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.
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.
Diagnosis of immunodeficiency or receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days prior to the first dose of trial treatment.
Prior anti-cancer therapy with a monoclonal antibody (mAb) within 4 weeks prior to study Day 1 or not recovered from adverse events (improved to grade 1 or less) due to mAbs administered more than 4 weeks earlier.
Prior chemotherapy, targeted small molecule therapy, or radiation therapy within 2 weeks (12 weeks for measurable sites of CNS disease) prior to study Day 1 or not recovered from adverse events (improved to grade 1 or less) due to a previously administered agent. Note: Subjects with neuropathy or ≤ Grade 2 alopecia 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.
Known additional malignancy that is progressing or requires active treatment except superficial malignancies of the skin and in situ cervical cancer
Has an 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.
Has history of (non-infectious) pneumonitis that required steroids, evidence of interstitial lung disease or active non-infectious pneumonitis.
Active infection requiring systemic therapy at enrollment.
Has a known history of active TB (Bacillus Tuberculosis)
Hypersensitivity to pembrolizumab or any of its excipients
Has received a live virus vaccine within 30 days of planned start of trial treatment.
Pregnant, breastfeeding, or expecting to conceive or father children within the projected duration of the trial, starting with the screening period through 120 days after the last dose of trial treatment
Prior therapy with an anti-programmed cell death 1 (PD-1), anti-programmed cell death 1 ligand (PDL-1), anti-PD-L2, or with an agent directed to another co-inhibitory T-cell receptor (e.g. CTLA-4, OX-40, CD137)
Known history of human immunodeficiency virus (HIV)
Known active Hepatitis B (e.g., HBsAg reactive) or Hepatitis C (e.g., HCV RNA [qualitative]).
Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial
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.
