Study summary

The study evaluates safety of adavosertib in monotherapy, and in combination with 5-Fluorouracil (5-FU) alone or with 5-FU/cis-diamminedichloroplatinum (CDDP) in Japanese participants with solid tumor. The primary hypothesis is that adavosertib is safe and tolerable in participants with locally advanced or metastatic solid tumors.

What researchers measure

Primary outcomes

  1. Number of Participants With Dose Limiting Toxicities (DLTs)

    DLT was defined using National Cancer Institute Common Terminology Criteria for Adverse Events version 3.0 and included: any drug-related hematologic toxicity ≥Grade 4 with the exception of Grade 4 neutropenia \<7 days duration; Grade 3 or 4 neutropenia with fever \>38.5 degrees Celsius and/or infection or neutropenia requiring colony-stimulating factor OR non-hematologic DLTs that were any Grade 3, 4, or 5 toxicity with the following exceptions: Grade 3 nausea, vomiting, diarrhea, and dehydration occurring in a setting of inadequate treatment; inadequately treated hypersensitivity reactions; Grade 3 elevated transaminases or urine electrolyte abnormality ≤1 week in duration; Grade 3 serum electrolyte abnormality ≤72 hours in duration. DLTs also included: drug-related adverse experience that lead to a dose modification; unresolved drug-related toxicity preventing treatment for ≥3 weeks or preventing administration of ≥8 of 10 doses in Parts 1 or 2A1 or 4 of 5 doses in Part 2A2.

    Time frame: Cycle 1 (21 days)

  2. Maximum Tolerated Dose (MTD) of MK1775 in Combination With 5-FU/CDDP Determined by Number of DLTs Per Dose Level: Locally Advanced or Metastatic Esophageal, Head and Neck, or Gastric Cancer

    The maximum tolerated dose (MTD) of MK-1775 in combination with 5-FU/CDDP for participants with locally advanced or metastatic esophageal, head and neck, or gastric cancer was determined based on DLTs that occurred during Cycle 1 of Parts 2B and 3. The MTD for MK-1775 in combination with 5-FU/CDDP was defined as the dose level at which approximately 30% of the participants were expected to experience a DLT for the combination therapy. The study was terminated early and Parts 2B and 3 were not performed. No participants received the 5-FU/CDDP regimen therefore the MTD for MK-1775 in combination with 5-FU/CDDP was not established.

    Time frame: Cycle 1 (21 days)

Secondary outcomes

    The maximum tolerated dose (MTD) of MK-1775 in combination with 5-FU/CDDP for participants with locally advanced or metastatic solid tumors was determined based on DLTs that occurred during Cycle 1 of Parts 2B and 3. The MTD for MK-1775 in combination with 5-FU/CDDP was defined as the dose level at which approximately 30% of the participants were expected to experience a DLT for the combination therapy. The study was terminated early and Parts 2B and 3 were not performed. No participants received the 5-FU/CDDP regimen therefore the MTD for MK-1775 in combination with 5-FU/CDDP was not established.
