A Study of the Safety, Tolerability, and Efficacy of MK-8353 in Participants With Advanced Solid Tumors (MK-8353-001 AM4)

• Number of participants with dose-limiting toxicities (DLTs) [ Time Frame: Cycle 1 of Part 1 only (approximately 28 days) ] [ Designated as safety issue: Yes ]
• Number of participants with complete response (CR) or partial response (PR) [ Time Frame: Baseline, and every 8 weeks until disease progression or discontinuation from study ] [ Designated as safety issue: No ]

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.

Inclusion Criteria:

• Pathologically/histologically confirmed solid tumor (metastatic or locally advanced disease) that has failed to respond to standard therapy, progressed despite standard therapy, or for which standard therapy does not exist.
• Participants of childbearing potential must have negative pregnancy test; females and male must agree to use effective contraception during the course of the trial and for 90 days after stopping study drug.
• For Part 1b and Part 2, participant with metastatic melanoma or metastatic colorectal cancer with at least one measurable lesion
• Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1 with a life expectancy of ≥3 months.
• Adequate organ function.

Exclusion Criteria:

• Unstable or progressing central nervous system (CNS) metastasis unless asymptomatic for 3 months, with no need for steroids or antiseizure medications.
• Active gastrointestinal disease or a disorder or a history of surgery that significantly alters gastrointestinal motility or absorption.
• Has not recovered from previous therapy and had any chemotherapy, biologic, or hormonal therapy within 4 weeks of study enrollment.
• Radiation therapy (except palliative radiation to bone lesions) within 4 weeks of study enrollment.
• More than 3 prior regimens of chemotherapy, biologic therapy, hormonal therapy, or investigational drugs not including adjuvant or neoadjuvant treatments.
• Clinically relevant cardiovascular, hepatic, neurologic, endocrine, or other major systemic diseases.
• Mean QTcF interval (interval on the electrocardiogram corrected for heart rate using Fridericia's correction) > 450 msec at baseline.
• Known Human Immunodeficiency Virus (HIV) infection, hepatitis infection, or tuberculosis infection.
• Current participation in any other interventional clinical study.
• History of significant eye disease, including glaucoma, retinopathy, or retinal vein occlusion.
