Brief summary

This study will investigate the safety, side effects and how well the body tolerates MK-5108 as well as determine different doses of MK-5108 in participants with advanced and/or refractory solid tumors. The corresponding primary hypotheses of this study are that 1) administration of oral MK-5108 (twice daily for 2 out of 14-21 days) to participants with advanced and/or refractory solid tumors will be safe and tolerable, and that 2) the spectrum of side effects observed in these participants after administration of oral MK-5108 alone and in combination with docetaxel will be dose-dependent and allow for definition of a maximum tolerated dose (MTD).

Interventions

DRUGMK-5108

MK-5108 will be administered orally, every 12 hours (Q12H) during the first 2 days of each cycle. Cycle length will be 14-21 days in Panel 1 and 21 days in Panel 2.

DRUGdocetaxel

Docetaxel will be administered intravenously (I.V.) at a dose of 60 mg/m\^2 Q12H during the first 2 days of each 21-day cycle.

MeasureTime frameDescription
Number of Participants Who Experienced an Adverse Event (AE)From Day 1 of study treatment until 30 days following the last dose of study treatment (up to 577 days)An AE was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the Sponsor's product, whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition which is temporally associated with the use of the Sponsor's product, was also an AE. The number of participants who experienced an AE was reported for each dose level group.
Number of Participants With Dose Limiting Toxicities (DLTs)Day 1 to Day 21 of study treatment (Cycle 1 for Panel 1, Panel 2, or Crossover)DLTs were AEs considered related to study drug that prevented escalation of the drug dose. Hematologic DLTs included any Grade 5 hematologic toxicity, Grade 4 neutropenia lasting for ≥7 days in duration, Grade 3 or Grade 4 neutropenia with fever \>38.5°C and/or infection requiring antibiotic or anti-fungal treatment, and Grade 4 thrombocytopenia (≤25.0 x 10\^9/L). Non-hematologic DLT was defined as any Grade 3, 4, or 5 non-hematologic toxicity, with the specific exceptions of: Grade 3 nausea or Grade 3 vomiting, Grade 3 diarrhea, or Grade 3 dehydration occurring in the setting of inadequate compliance with supportive care and lasting for \<48 hours, alopecia, inadequately treated hypersensitivity reactions, or Grade 3 elevated transaminases of ≤1 week in duration. Any drug-related AE leading to a dose modification of MK-5108, or any unresolved drug-related toxicity persisting\>6 weeks, was also considered a DLT.

Participant flow

Pre-assignment details

35 participants were enrolled and treated in this study. 14 enrolled into Panel 1 and received MK-5108 monotherapy. An additional 4 enrolled into Panel 1 and received MK-5108 as monotherapy prior to crossing over to Panel 2 and receiving MK-5108 with docetaxel. 17 enrolled into Panel 2 and received only the combination of MK-5108 and docetaxel.

Number of Participants Who Experienced an Adverse Event (AE)

An AE was defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the Sponsor's product, whether or not considered related to the use of the product. Any worsening (i.e., any clinically significant adverse change in frequency and/or intensity) of a pre-existing condition which is temporally associated with the use of the Sponsor's product, was also an AE. The number of participants who experienced an AE was reported for each dose level group.

Time frame: From Day 1 of study treatment until 30 days following the last dose of study treatment (up to 577 days)

Population: All participants that received one or more doses of study medication. Four participants who received MK-5108 monotherapy in Panel 1 and then crossed over to receive combination treatment in Panel 2 (Crossover) were included in both respective treatment groups and AEs were reported according to treatment received.
