Brief Summary

Background: Medullary thyroid cancer (MTC) is a tumor of the thyroid gland. Surgery is the only current treatment to cure it. The drug pembrolizumab (MK-3475) is a new type of cancer therapy. It works by allowing the immune system to detect and kill tumor cells. Objective: To test how pembrolizumab affects people with MTC and if it can offer them clinical benefit. Eligibility: People ages 18 and older with MTC Patients who have recurrent or metastatic MTC, for whom surgery is not a curative option Patients with some imaging evidence of MTC Patients with minimal symptoms related to MTC Design: Participants will be screened with:

• Medical history
• Physical exam
• Blood, urine, and heart tests
• Computed tomography (CT) scan or magnetic resonance imaging (MRI): They lie in a machine that takes pictures of the body.
• Bone scan Participants will be put in a group based on their treatment history:
• Group 1 if they have had an immune stimulating cancer vaccine
• Group 2 if they have had no vaccine Participants will receive the study drug as a 30-minute intravenous (IV) infusion every 3 weeks. Treatment will continue for up to 2 years as long as they tolerate it and their disease does not get worse. Participants will have physical exams and blood tests on the day of each infusion. They will have CT and bone scans every 3 months. Participants may save biopsies before treatment and after starting treatment. Participants will have a final visit 3-4 weeks after stopping treatment. This will include a physical exam and blood and heart tests. After this study, participants can join a long-term follow-up study.

Outcome Measures

Primary Outcomes (2)

• Clinical Response

  Participants with medullary thyroid cancer were administered a programmed cell death protein 1 (PD1) inhibitor to determine if any experienced a 50% or greater decline in calcitonin levels. A calcitonin response is defined as participants with a ≥50% decline from baseline that is then confirmed on a subsequent calcitonin assessment at least one week later.

  2 years

• Percentage of Participants With a Partial Response and Complete Response by Computed Tomography (CT) or Magnetic Resonance Imaging (MRI)

  Participants were imaged by CT or MRI and followed for response using the Immune-Related Response Criteria (irRC). Partial Response is a ≥30% decrease in the sum of the largest diameter (SLD) compared with baseline confirmed by a consecutive assessment at least 4 weeks after the first documentation. Complete Response is a 100% disappearance of all lesions, whether measurable or not, and no new lesions, in two consecutive observations not less than 4 weeks from the date first documented.

  2 years

Secondary Outcomes (8)

• Percentage Change in (Cluster of Differentiation 4 (CD4), CD8, Tregs, and Natural Killer (NK) Cells at Day 1 and 84 Days in All Participants

  Day 1 and 84 days

• Number of Participants With a Sustained Decline in Carcinoembryonic Antigen (CEA)

  every 3 weeks while on treatment and post treatment, up to 2 years

• Number of Participants With a Sustained Decline in Calcitonin

  every 3 weeks while on treatment and post treatment, up to 2 years

• Progression-free Survival (PFS)

  3 weeks for up to 2 years while on treatment than 2 weeks after last treatment

• Overall Survival at 2 Years

  2 years

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Diagnosis: Patients must have histologically confirmed medullary thyroid cancer by the Laboratory of Pathology or a pathology report and history consistent with medullary thyroid cancer. It is not uncommon for a secondary, minor pathologic focus of another form of thyroid cancer to be coincidentally found in 15-20% of patients with medullary thyroid cancer. In such cases, eligibility is based on the discretion of the investigator.
• Patients must have evidence of metastatic medullary thyroid cancer including disease that is evaluable on bone, computed tomography (CT) scan or magnetic resonance imaging (MRI). (Patients who are surgical candidates and potentially rendered disease free with surgical resection are not eligible.)
• Patients must have elevated calcitonin levels greater than 40 pg/mL
• Patients must have minimal or no disease related-symptoms (Minimal symptoms will include those that do not affect activities of daily living or pain that does not require regularly scheduled narcotics.)
• Patients must have evaluable disease on imaging
• No history of seizures, encephalitis, or multiple sclerosis.
• Age greater than or equal to 18 years
• Eastern Cooperative Oncology Group (ECOG) performance status of 0-1 at study entry (Karnofsky greater than or equal to 70).
• 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.
• Female subjects of childbearing potential must be willing to use an adequate method of contraception, 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
• Male subjects of childbearing potential must agree to use an adequate method of contraception. 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
• Willing to travel to the National Institutes of Health (NIH) for follow-up visits
• Able to understand and sign informed consent.
• Demonstrate adequate organ function, all screening labs should be performed within 10 days of treatment initiation.
• Adequate Organ Function Laboratory Values

You may not qualify if:

• 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.
• 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.
• Has a known history of active TB (Bacillus Tuberculosis)
• Hypersensitivity to pembrolizumab or any of its excipients.
• Has had a prior anti-cancer monoclonal antibody (mAb) within 4 weeks prior to study Day 1 or who has not recovered (i.e., less than or equal to Grade 1 or at baseline) from adverse events due to agents administered more than 4 weeks earlier.
• Has had prior targeted small molecule therapy, or radiation therapy within 2 weeks prior to study Day 1 or who has not recovered (i.e., less than or equal to Grade 1 or at baseline) from adverse events due to a previously administered agent. Note: Subjects with less than or equal to 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.
• 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.
• Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis. Subjects with previously treated brain metastases may participate provided they are stable for 6 months (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.
• Has history of (non-infectious) pneumonitis that required steroids, evidence of interstitial lung disease or active, non-infectious pneumonitis.
• Has an active infection requiring systemic therapy.
• Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subjects 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.
• Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial.
• Is pregnant or breast feeding 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.
• Has received prior therapy with an anti-Programmed cell death protein 1 (PD-1), anti- programmed cell death-1 ligand 1 (PD-L1), or anti-Programmed death ligand 2 (PD-L2) agent.
• Has Human Immunodeficiency Virus (HIV) (HIV 1/2 antibodies).
