A Dose Escalation Study of Adavosertib(MK1775) in Combination With 5-FU or 5-FU/CDDP in Patients With Advanced Solid Tumor (1775-005

August 31, 2023 updated by: Merck Sharp & Dohme LLC

A Phase I Dose Escalation Study of MK1775 in Monotherapy, in Combination With 5-Fluorouracil, and in Combination With 5-Fluorouracil and Cisplatin in Patients With Advanced Solid Tumor

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.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Participants With Dose Limiting Toxicities (DLTs)
Time Frame: Cycle 1 (21 days)
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.
Cycle 1 (21 days)
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
Time Frame: Cycle 1 (21 days)
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.
Cycle 1 (21 days)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
MTD of MK1775 in Combination With 5-FU/CDDP Determined by Number of DLTs Per Dose Level: Locally Advanced or Metastatic Solid Tumors
Time Frame: Cycle 1 (21 days)
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.
