A Combination Therapy Study of MK-2206 and AZD6244 in Participants With Advanced Solid Tumors (MK-2206-010)

A Phase I Study of Oral MK-2206 in Combination With Oral AZD6244 in Patients With Locally Advanced or Metastatic Solid Tumors

This study will investigate the safety and tolerability of combination therapy with MK-2206 and AZD6244 (selumetinib) and determine the maximum tolerated dose (MTD) and recommended Phase 2 dose (RPTD) for this drug combination in the treatment of participants with locally advanced or metastatic solid tumors. Preliminary efficacy data will also be collected.

The primary hypotheses for this study are that: 1) the Dose-limiting Toxicities (DLTs) observed in participants with locally advanced or metastatic solid tumors after administration of combination therapy with MK-2206 and AZD6244 will be dose-dependent and allow for identification of the MTD, and 2) oral administration of combination therapy with MK-2206 and AZD6244 to participants with advanced solid tumors will be generally well-tolerated.

Inclusion Criteria:

• Participant has confirmed metastatic or locally advanced solid tumor that has failed to respond to standard therapy, progressed despite standard therapy, or therapies known to provide clinical benefit, or for whom efficacious standard therapy or any other therapy known to provide clinical benefit does not exist
• Participant has no history of prior cancer, except certain cervical, skin, or prostate cancers, or has undergone potentially curative therapy with no evidence of disease for 5 years
• At least 18 years of age
• Participant is able to swallow oral medications
• For participants enrolled in the MTD expansion cohorts, must have a diagnosis of Kirsten rat sarcoma viral oncogene homolog (KRAS) tumor-type non small-cell lung cancer (NSCLC). Additional tumor types (with specific mutations) may be added to the MTD expansion cohorts after discussion between Sponsor and Investigator

• Participant has known central nervous system metastases and/or carcinomatous meningitis
• Participant has a primary central nervous system tumor or spinal cord compression
• Participant is, at the time of signing informed consent, a regular user (including "recreational use") of any illicit drugs or had a recent history (within the last year) of drug or alcohol abuse
