This trial will evaluate the safety and efficacy of vicriviroc (MK-7690) at 2 dose levels in combination with pembrolizumab (MK-3475) in participants with advanced/metastatic microsatellite stable (MSS) colorectal cancer (CRC).

Safety and Efficacy of Vicriviroc (MK-7690) in Combination With Pembrolizumab (MK-3475) in Participants With Advanced/Metastatic Microsatellite Stable (MSS) Colorectal Cancer (CRC) (MK-7690-046)

Objective 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 Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 by the investigator. ORR was estimated and analyzed using Clopper-Pearson interval.

DLTs were assessed during the first cycle (21 days) \& were defined as: Grade (Gr) 4 nonhematologic toxicity; Gr 4 hematologic toxicity lasting ≥7 days, except thrombocytopenia, Gr 4 thrombocytopenia of any duration, Gr 3 thrombocytopenia associated with bleeding; nonhematologic adverse event (AE) ≥ Gr 3 (with exceptions); Gr 3 or 4 nonhematologic lab abnormality (if medical intervention was required, lead to hospitalization, or persisted for \>72 hours); Gr 3 or 4 febrile neutropenia; inability to receive ≥75% of the planned vicriviroc dose because of drug-related tolerability; drug-related toxicity that caused a \>2 week delay in Cycle 2 initiation; elevated aspartate aminotransferase or alanine aminotransferase lab value that is \>3× upper limit of normal (ULN) \& an elevated total bilirubin value \>2× ULN \& an alkaline phosphatase value \<2× ULN, in which no alternative reasons were found.

An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a study intervention. The number of participants with at least one AE was assessed.

The number of participants who discontinued treatment due to an AE was assessed

An objective response rate was defined as the percentage of participants who experienced an immune-based complete response (iCR: disappearance of all target lesions) or immune-based partial response (iPR: at least a 30% decrease in the sum of diameters of target lesions). The percentage of participants who experienced an iCR or iPR using immune-based therapeutics Response Evaluation Criteria in Solid Tumors (iRECIST) per investigator was presented. ORR was estimated and analyzed using Clopper-Pearson interval.

PFS was defined as the time from the first dose of study treatment to the date of the first documentation of disease progression, as determined by investigator per RECIST 1.1 or death due to any cause (whichever occurred first). Disease progression was defined as at least 20 percent (%) increase (including an absolute increase of at least 5 millimeter \[mm\]) in the sum of diameter of target lesions, taking as reference the smallest sum and/or unequivocal progression of existing non-target lesions and/or appearance of 1 or more new lesions. PFS was estimated and analyzed using Kaplan-Meier method.

PFS was estimated and analyzed using Kaplan-Meier method.

OS is defined as the time from the first dose of study treatment until death from any cause.

Plasma vicriviroc concentration was quantified for each arm to determine AUC 0-8hrs, defined as the area under the concentration vs. time curve for vicriviroc from 0 to 8 hours.

Plasma vicriviroc concentration was quantified for each arm to determine Cmax, defined as the maximum observed concentration of vicriviroc in plasma.

Plasma vicriviroc concentration was quantified for each arm to determine Ctrough, defined as the minimum plasma concentration of vicriviroc observed after administration and just before the subsequent dose.

All-cause mortality includes all randomized participants. Safety includes participants who received ≥1 dose of study treatment. Per protocol, disease progression was not considered an AE, unless related to study treatment. Thus, MedDRA preferred terms "Neoplasm progression", "Malignant neoplasm progression" and "Disease progression" not related to study treatment were excluded as AEs.

Participants received vicriviroc 150 mg tablets per os (PO) every day (QD) of each 21-day cycle up to 35 cycles and pembrolizumab 200 mg administered as a 30-minute intravenous (IV) infusion on Day 1 of each 21 day cycle up to 35 cycles (cycle length: 21 days).
