A Study of the Safety, Tolerability, and Efficacy of MK-8353 in Participants With Advanced Solid Tumors (MK-8353-001)
- Registration Number
- NCT01358331
- Lead Sponsor
- Merck Sharp & Dohme LLC
- Brief Summary
This study of the safety, tolerability, and efficacy of MK-8353 (formerly SCH 900353) given as single agent oral therapy for participants with advanced solid tumors will be done into two parts. In Part 1a, there will be a dose escalation to find the preliminary maximum tolerated dose (MTD), and in Part 1b, dose confirmation to find out the recommended Phase 2 dose (RPTD) that will be used in Part 2 of the study. In Part 2 of the study, participants with certain types of metastatic melanoma or metastatic colorectal cancer will be treated to see if MK-8353 is effective as single agent therapy.

- Primary Outcome Measures
Name Time Method Number of Participants With Dose-Limiting Toxicities (DLTs) Cycles of 28 days, up to approximately 9 months treatment and a 30-day follow-up period for a total time of up to approximately 10 months DLT was derived from the toxicities observed during the first cycle (28 days) for each dose level. DLT is defined as any hematologic or non-hematologic toxicity ≥Grade 3 as pre-specified per protocol, or drug-related toxicity, regardless of Common Terminology Criteria for Adverse Events (CTCAE) grade that causes \>20% of the intended total number of doses in Cycle 1 to be missed.
Number of Participants With Overall Response Rate Baseline, and every 8 weeks until disease progression or discontinuation from study up to approximately 10 months Overall Response rate is defined as the number of participants who had a Complete Response (CR: Disappearance of all target lesions) or Partial Response (PR: At least a 30% decrease in the sum of diameters of target lesions) per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.
