Brief summary

The primary purpose of this study is to investigate the Dose Limiting Toxicities (DLTs), pharmacokinetics (PK), and pharmacodynamics (PD) of MK-2206 administered orally to participants with advanced solid tumors. The preliminary efficacy of MK-2206 will also be investigated.

Interventions

MK-2206 administered as an oral formulation in rising dose levels on a QOD schedule (30 mg, 60 mg, 75 mg, and 90 mg) or QW schedule (90 mg, 135 mg, 200 mg, 250 mg, and 300 mg) in repeating 4 week cycles, depending upon allocation.

Number of Participants With Dose Limiting Toxicities (DLTs)Day 1 to Day 28 (Cycle 1)DLT was any drug-related AE, regardless of grade, leading to a dose modification of MK-2206. Dose-limiting hematologic and nonhematologic toxicities were defined differently and were based on events occurring during the first cycle of study drug administration. Hematologic DLT defined as any Grade (Gr) 4 or greater hematologic toxicity except neutropenia described as follows: Neutropenia that was Gr 4 lasting for ≥7 days, or Gr 3/Gr 4 with fever \>38.5°C and/or infection requiring antibiotic or anti-fungal treatment considered DLT. Gr 4 thrombocytopenia (≤25.0 x 10\^9/L) was also considered DLT. Non-hematologic DLTs were defined as any Gr 3, 4, or 5 nonhematologic toxicity, with the specific exceptions of: Gr 3 nausea, vomiting, diarrhea, or dehydration occurring with inadequate supportive care and lasting \<48 hours; alopecia; inadequately treated hypersensitivity reactions; and Gr 3 elevated transaminases of ≤1 week in duration. A participant could have more than one DLT.
Number of Participants With One or More Adverse Events (AE)Up to 269 daysAn 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 was temporally associated with the use of the SPONSOR's product, was also an AE. The number of participants that experienced one or more AEs was reported for each dose level group.

Secondary

MeasureTime frameDescription
Number of Participants With Confirmed Response as Per Response Evaluation Criteria in Solid Tumors (RECIST)From Cycle 1 Day 1 through the End of Study Visit (up to 6 months)Overall tumor response was assessed during the study by diagnostic anatomic imaging using RECIST. The number of participants with a confirmed Complete Response (CR: Disappearance of all target lesions) as per RECIST was reported for each dose level group.
Phosphorylated Protein Kinase B (pAkt) Level on Cycle 1 Day 15 (C1D15) After Treatment With MK-2206 at the Maximum Tolerated Dose (MTD)Baseline, Cycle 1 Day 15To determine the inhibition of pAkt by MK-2206 in participants treated at the MTD, levels of Akt phosphorylated at the serine 473 residue (pAkt Ser473 Akt) were measured in snap-frozen tumors collected at baseline and Day 15 of Cycle 1 using a MesoScale enzyme-linked immunosorbent assay (ELISA). Per protocol, pAkt levels were determined only for the MK-2206 MTD (60 mg QOD) group.

Number of Participants With Dose Limiting Toxicities (DLTs)

DLT was any drug-related AE, regardless of grade, leading to a dose modification of MK-2206. Dose-limiting hematologic and nonhematologic toxicities were defined differently and were based on events occurring during the first cycle of study drug administration. Hematologic DLT defined as any Grade (Gr) 4 or greater hematologic toxicity except neutropenia described as follows: Neutropenia that was Gr 4 lasting for ≥7 days, or Gr 3/Gr 4 with fever \>38.5°C and/or infection requiring antibiotic or anti-fungal treatment considered DLT. Gr 4 thrombocytopenia (≤25.0 x 10\^9/L) was also considered DLT. Non-hematologic DLTs were defined as any Gr 3, 4, or 5 nonhematologic toxicity, with the specific exceptions of: Gr 3 nausea, vomiting, diarrhea, or dehydration occurring with inadequate supportive care and lasting \<48 hours; alopecia; inadequately treated hypersensitivity reactions; and Gr 3 elevated transaminases of ≤1 week in duration. A participant could have more than one DLT.

Time frame: Day 1 to Day 28 (Cycle 1)

Population: The All Participants as Treated (APaT) population: All participants who received at least one dose of study treatment.

Number of Participants With One or More Adverse Events (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 was temporally associated with the use of the SPONSOR's product, was also an AE. The number of participants that experienced one or more AEs was reported for each dose level group.

Number of Participants With Confirmed Response as Per Response Evaluation Criteria in Solid Tumors (RECIST)

Overall tumor response was assessed during the study by diagnostic anatomic imaging using RECIST. The number of participants with a confirmed Complete Response (CR: Disappearance of all target lesions) as per RECIST was reported for each dose level group.

Time frame: From Cycle 1 Day 1 through the End of Study Visit (up to 6 months)

Population: All participants with measurable disease at baseline per RECIST.

Phosphorylated Protein Kinase B (pAkt) Level on Cycle 1 Day 15 (C1D15) After Treatment With MK-2206 at the Maximum Tolerated Dose (MTD)

To determine the inhibition of pAkt by MK-2206 in participants treated at the MTD, levels of Akt phosphorylated at the serine 473 residue (pAkt Ser473 Akt) were measured in snap-frozen tumors collected at baseline and Day 15 of Cycle 1 using a MesoScale enzyme-linked immunosorbent assay (ELISA). Per protocol, pAkt levels were determined only for the MK-2206 MTD (60 mg QOD) group.

Time frame: Baseline, Cycle 1 Day 15

Population: Participants treated at the MTD (60 mg QOD) dose level with measurable disease at baseline per RECIST and paired tumor samples at baseline and C1D15. Per protocol, no other dose level groups were analyzed.
