Brief summary:
The purposes of this study were to estimate the relative (Rel) bioavailability (BA) of an oral solution (OS) formulation of alisertib in reference to a powder-in-capsule (PIC) formulation, to characterize the effect of food on the single-dose pharmacokinetics (PK) of alisertib OS and enteric-coated tablets (ECT), to characterize the multiple-dose safety, tolerability, and steady-state PK of alisertib administered as an OS, and to characterize the multiple-dose safety and tolerability of alisertib administered as an ECT.

Detailed description:
The drug being tested in this study is called alisertib (MLN8237). Alisertib is being tested to treat people who have advanced solid tumors. This study will look at the relative bioavailability (BA) (Part A), food effect and multiple-dose PK and safety of the oral solution (OS) (Part B) and food effect and safety of the enteric-coated tablet (ECT) formulation (Part C).

The study enrolled 53 patients (pts). Prior to initiation of Part A, 4 participants were enrolled in a dose escalation cohort. Participants in the study received:

• Alisertib 15 mg to 50 mg orally In the first 2 cycles of all 3 parts of the study, a single dose of alisertib was administered on Day 1 (PIC or OS in Part A \[n=19 pts\]; OS, in the fed or fasted state, in Part B \[n=6 pts\]; ECT, in the fed or fasted state, in Part C \[n=24 pts\]), In Part A, participants then continued on the PIC formulation at 40 mg BID for 7 days (Days 3 - 9). In Part B, participants continued on the OS formulation at a calculated dose administered BID for 7 days (Days 3 - 9). In Part C, the ECT formulation was continued at 40 mg BID for 7 days (Days 3 - 9); however, dose escalation to 50 mg BID was permitted after Cycle 1 based on tolerability and safety findings in the prior cycles. All participants took doses at a gap of 12 hours each day for 7 days followed by a 14-day rest period in a 21-days cycle for the remaining cycles.

This multi-center trial was conducted in the United States. The overall time to participate in this study was 30 months. Participants made multiple visits to the clinic, and final assessments were performed approximately 30 days after last dose of study drug.

Arms:
arm 1: A single dose of alisertib 15 mg, oral solution (OS) was administered on Day 1, followed by alisertib 40 mg, powder-in-capsule (PIC), orally, twice a day (BID) on Days 3 through 9, followed by a 14-day rest period in Cycle 1 in a 23-day cycle. A single dose of alisertib 50 mg PIC, orally, was administered on Cycle 2 Day 1 followed by alisertib 40 mg on Days 3 through 9, followed by a 14-day rest period in Cycle 2 in a 23-day cycle. Subsequent cycles, alisertib 40 or 50 mg (individual dosage based on tolerability in Cycles 1 and 2), PIC, orally, BID on Days 1 through 7, followed by a 14-day rest period in 21-day cycles until disease progression, occurrence of an unacceptable alisertib-related toxicity, or the start of another anticancer therapy. arm 2: A single dose of alisertib 25 mg, OS, administered on Day 1, followed by alisertib 40 mg PIC, orally, BID on Days 3 through 9, followed by a 14-day rest period in Cycle 1, in a 23-day cycle. A single dose of alisertib 50 mg PIC, orally, administered on Cycle 2 Day 1, followed by alisertib 40 mg, PIC, orally, BID on Days 3 through 9, followed by a 14-day rest period in a 23-day cycle. Subsequent cycles, alisertib 40-50 mg (individual dosage based on tolerability in Cycles 1 and 2), PIC, orally, BID on Days 1 through 7, followed by a 14-day rest period in 21-day cycles until disease progression, occurrence of an unacceptable alisertib-related toxicity, or the start of another anticancer therapy. arm 3: A single dose of alisertib 50 mg, PIC, orally administered on Day 1, followed by alisertib 40 mg, PIC, orally, BID on Days 3 through 9, followed by a 14-day rest period in Cycle 1, in a 23-day cycle. Cycle 2 Day 1 alisertib 25 mg, OS, once on Day 1, followed by alisertib 40 mg, PIC, orally, BID on Days 3 through 9, followed by a 14-day rest period in a 23-day cycle. Subsequent cycles followed by alisertib 40-50 mg (individual dosage based on tolerability in Cycles 1 and 2), PIC, orally, BID on Days 1 through 7, followed by a 14-day rest period in Cycle 3, in 21-day cycles until disease progression, occurrence of an unacceptable alisertib-related toxicity, or the start of another anticancer therapy. arm 4: Alisertib 35 mg (35 mg = relative bioavailability estimate in Part A as dose of OS that was calculated to yield the area under the concentration time curve of a 50-mg PIC dose): A single dose of alisertib 35 mg oral solution (OS), in fed state, administered on Day 1, followed by alisertib 30 mg, OS, BID on Days 3-9, followed by a 14-day rest period in Cycle 1, in a 23-day cycle. Cycle 2 Day 1 alisertib 35 mg administered, OS, in fasted state, once on Day 1, followed by alisertib 30 mg, OS, BID on Days 3-9, followed by a 14-day rest period in a 23-day cycle. Cycle 3 onwards, participants received alisertib 40 mg, PIC, orally, BID on Days 1-7, with dose reduction to 30 mg BID or escalation to 50 mg BID permitted, based on individual tolerance, followed by a 14-day rest period, in 21-day cycles until disease progression, occurrence of an unacceptable alisertib-related toxicity, or the start of another anticancer therapy. arm 5: A single dose of alisertib 35 mg, OS, in fasted state, administered on Day 1, followed by alisertib 30 mg, OS, BID on Days 3-9, followed by a 14-day rest period in a 23-day cycle.
