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.

| Primary | 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 | |
| Primary | 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 | Percentage Change in (Cluster of Differentiation 4 (CD4), CD8, Tregs, and Natural Killer (NK) Cells at Day 1 and 84 Days in All Participants | Regulatory T-Cells (CD4, CD8, Tregs, and NK cells) in peripheral blood mononuclear cell (PBMC)s were measured by 7-color flow cytometry. | Day 1 and 84 days | |
| Secondary | Number of Participants With a Sustained Decline in Carcinoembryonic Antigen (CEA) | A sustained 50% decline in CEA. A large magnitude decline in CEA may be associated with tumor responses. | every 3 weeks while on treatment and post treatment, up to 2 years | |
| Secondary | Number of Participants With a Sustained Decline in Calcitonin | A sustained 50% decline in calcitonin. A large magnitude decline in calcitonin may be associated with tumor responses. | every 3 weeks while on treatment and post treatment, up to 2 years | |
| Secondary | Progression-free Survival (PFS) | PFS is defined as the duration of time from start of treatment to time of progression or death, whichever occurs first. Progression, assessed by the Immune-Related Response Criteria (irRC), is defined as at least 20% increase in the sum of the largest diameter (SLD) compared with nadir (minimum recorded tumor burden) and an increase of at least 5mm over the nadir, confirmed by a repeat,consecutive observations at least 4 weeks from the date first documented. | 3 weeks for up to 2 years while on treatment than 2 weeks after last treatment | |
| Secondary | Overall Survival at 2 Years | Percentage of participants who are alive at 2 years. | 2 years | |
| Secondary | Number of Participants With Grade =1 Adverse Events Possibly, Probably, or Definitely Related to Pembrolizumab | Adverse events were assessed by the Common Terminology Criteria for Adverse Events (CTCAE v4.0). Grade 1 is mild. Grade 2 is moderate. Grade 3 is severe or medically significant but not immediately life-threatening. Grade 4 is life-threatening; urgent intervention indicated. Grade 5 is death related to adverse event. | Date treatment consent signed to date off study, approximately 25 months and 28 days for cohort 1 and 18 months and 12 days for cohort 2. | |
| Secondary | Number of Participants With Grade =1 Adverse Events Unlikely or Unrelated to Pembrolizumab | Adverse events were assessed by the Common Terminology Criteria for Adverse Events (CTCAE v4.0). Grade 1 is mild. Grade 2 is moderate. Grade 3 is severe or medically significant but not immediately life-threatening. Grade 4 is life-threatening; urgent intervention indicated. Grade 5 is death related to adverse event. | Date treatment consent signed to date off study, approximately 25 months and 28 days for cohort 1 and 18 months and 12 days for cohort 2. | |
| Secondary | Number of Participants With Serious and Non-serious Adverse Events Assessed by the Common Terminology Criteria for Adverse Events (CTCAE v4.0) | Here is the number of participants with serious and non-serious adverse events assessed by the Common Terminology Criteria for Adverse Events (CTCAE v4.0). A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life-threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned. | Date treatment consent signed to date off study, approximately 25 months and 28 days for cohort 1 and 18 months and 12 days for cohort 2. |
