Pharmacokinetics of Alisertib in Adults With Advanced Solid Tumors or Relapsed/Refractory Lymphoma With Varying Degrees of Hepatic Function

The purpose of this study is to evaluate the effect of moderate or severe hepatic impairment on the single-dose pharmacokinetics of alisertib in adult participants with cancer.

The drug being tested in this study is called alisertib. Alisertib was tested to assess how it was processed by the body in participants with advanced solid tumors or relapsed/refractory lymphoma with varying degrees of liver function. This study also assessed laboratory results and safety. The study enrolled 36 participants. Participants were assigned to 1 of the 3 treatment groups based on the status of their liver function: Normal hepatic function (Total bilirubin ≤ upper limit of the normal range \[ULN\] and alanine aminotransferase \[ALT\] level ≤ ULN), moderate hepatic impairment (Total bilirubin \> 1.5-3 x ULN and ALT level = Any), or severe hepatic impairment (Total bilirubin \> 3 x ULN and ALT level = Any). All participants were administered one 50 mg dose of alisertib on Day 1, Cycle 1. Alisertib was administered again on Days 8 through 14 of Cycle 1, followed by a 14-day rest period. Doses administered on Days 8-14 were 50, 30, or 20 mg of alisertib, depending on hepatic function. Alisertib was then continued at the same dose as in Cycle 1, Days 8-14 in 21-day cycles (7 days of alisertib followed by a 14-day rest period) for up to 1 year (approximately 16 cycles). This multicenter trial was conducted in USA only. The overall time to participate in this study was up to 312 Days. Participants made multiple visits to the clinic including an end-of-study visit 30 days after the last dose of study drug for a follow-up assessment.
