Study Endpoints

Primary Endpoints

Overall Response Rate (ORR)
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.

Number of Participants Who Experienced Dose-limiting Toxicities (DLTs)
Cycle 1 (first dose and up to 4 weeks in Part A, 3 weeks in Parts B, C, E, and 6 weeks in Part D)

The following toxicities graded per the Common Terminology Criteria for Adverse Events version 4.0 (CTCAE v.4.0) were considered DLTs if judged by the investigator to be related to either study drug: * Grade (G) 4 neutropenia lasting \>7 days * Grade 3 and Grade 4 febrile neutropenia * Grade 4 thrombocytopenia (\<25,000/mm\^3) * Grade 4 anemia * Grade 4 non-hematologic toxicity (not laboratory) * Grade 3 non-hematologic toxicity (not laboratory) lasting \>3 days despite optimal supportive care * Any Grade 3 non-hematologic laboratory value if medical intervention is required to treat the participant or the abnormality persists for \>7 days. * (Part D only) Missing the second dose of pembrolizumab (Cycle1 Day 22) due to drug-related adverse event

Number of Participants Who Experienced at Least One Adverse Event (AE)
Up to approximately 51.3 months

An adverse event is defined as any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have to have a causal relationship with this treatment. An adverse event can therefore be any unfavourable and unintended sign (including an abnormal laboratory finding, for example), symptom, or disease temporally associated with the use of a medicinal product or protocol-specified procedure, whether or not considered related to the medicinal product or protocol-specified procedure. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a preexisting condition that is temporally associated with the use of the Sponsor's product, is also an adverse event.

Number of Participants Who Discontinued Study Treatment Due to an Adverse Event (AE)
Up to approximately 37.9 months

MK-3475 is in Phase 1 clinical development. It has received a Priority Review designation from the FDA. The drug is investigational and not yet approved, with ongoing trials assessing its use in various cancers.

What clinical trials is MK-3475 in?

MK-3475 is being studied in 17 clinical trials, with 5 active and 12 completed, enrolling over 8,000 participants. Notable trials include NCT02635360 for cervical cancer, NCT04875195 for Hodgkin's lymphoma and PMBCL, NCT04976634 for solid tumors, and NCT05815927 for head and neck cancer.

Is MK-3475 the same as pembrolizumab?

Yes, MK-3475 is the same as pembrolizumab, which is also known by the brand name KEYTRUDA. The drug is referred to by multiple names including Pembrolizumab 200 mg, Pembrolizumab Injection, and Pembrolizumab (MK-3475), among others.
