Overview
Brief Summary
This study will assess the efficacy and safety of pembrolizumab (MK-3475) administered to participants with incurable advanced biomarker-positive solid tumors that have not responded to current therapy or for which current therapy is not appropriate.
The study hypothesis is that administration of pembrolizumab to participants with some types of solid tumors will result in a clinically meaningful response rate.
Detailed Description
Qualified participants who complete up to \~2 years of pembrolizumab treatment but progress after discontinuation may be eligible for a second course of pembrolizumab for up to \~1 additional year, at the Investigator's discretion. Per protocol, response or progression during this second course will not count towards efficacy outcome measures and adverse events during this second course will not count towards safety outcome measures.

Eligibility Criteria
Inclusion Criteria
- •Histologically or cytologically documented locally-advanced and/or metastatic solid malignancy that is incurable, and has failed prior standard therapy or for which standard therapy is not appropriate
- •Have biomarker-positive solid tumor
- •Have measurable disease based on Response Criteria in Solid Tumors Version 1.1 (RECIST 1.1)
- •Eastern Cooperative Oncology Group (ECOG) Performance status of 0 or 1
- •Adequate organ function
- •Female participants 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
- •Male participants of childbearing potential must agree to use an adequate method of contraception starting with the first dose of study medication through 120 days after the last dose of study medication
Exclusion Criteria
- •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 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 central nervous system \[CNS\] disease) prior to study Day 1 or not recovered from adverse events due to a previously administered agent
- •Known additional malignancy that is progressing or requires active treatment excepting basal cell carcinoma of the skin, squamous cell carcinoma of the skin that has undergone potentially curative therapy, or in situ cervical cancer
- •Known active CNS metastases and/or carcinomatous meningitis
- •Has an active autoimmune disease that has required systemic treatment in 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 evidence of interstitial lung disease or a history of (non-infectious) pneumonitis that required steroids or has current pneumonitis
- •Active infection requiring systemic therapy
- •Known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial
Outcomes
Primary Outcomes
Overall Response Rate (ORR)
Time Frame: Up to approximately 86 months
Overall response rate (ORR) was defined as the percentage of participants who experienced a complete response (CR; disappearance of all target lesions) or a Partial Response (PR; at least a 30% decrease in the sum of diameters of target lesions) and was assessed using modified Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 by the investigator.
Secondary Outcomes
- Number of Participants Who Discontinued From Study Treatment Due to an AE(Up to approximately 25 months)
- Overall Survival (OS)(Up to approximately 86 months)
- Number of Participants Who Experienced an Adverse Event (AE)(Up to approximately 28 months)
- Progression Free Survival (PFS)(Up to approximately 86 months)
- Duration of Response (DOR)(Up to approximately 86 months)
