Overview
Brief Summary
The main purpose of this study is to evaluate the effect of varying degrees of impaired hepatic function (by Child Pugh classification) on the plasma PK of siremadlin after a single oral dose. In addition, safety and tolerability of siremadlin after a single oral dose will be evaluated. The results of this study will inform the decision whether a dose adjustment may be recommended when treating patients with various degrees of impaired hepatic function.
Detailed Description
Participants will be recruited into one of 4 groups according to the Child-Pugh classification score. Participants with HI will be enrolled into either mild (Child-Pugh A; Group 2), moderate (Child Pugh B; Group 3) or severe (Child-Pugh C; Group 4) HI groups. Healthy control participants (Group 1) will be matched to 1 or more participants with HI with respect to age (± 10 years), body weight (± 20%) and sex. Each participant in the matched healthy control group (Group 1) can be matched to participant(s) in any HI group (Groups 2, 3, and 4). The study will enroll the four groups in parallel. Therefore, enrollment in Group 1 will remain open until enrollment in the mild, moderate and severe HI groups is complete and each HI participant has a matched healthy control (Group 1) participant. Participants from Group 1 will be enrolled after at least 3 participants from each of Groups 2 and 3 have completed all scheduled assessments. The study consists of a screening period of up to 28 days (Days -29 to -2), a baseline evaluation on Day -1, a single dose administration of siremadlin on Day 1 followed by PK sampling up to 144 hours post-dose (Day 7). All baseline safety evaluation results must be available and reviewed prior to the dosing. All eligible participants will be domiciled from Day -1 until Day 7. Safety assessments will include physical examinations, ECGs, vital signs, standard clinical laboratory evaluations (hematology, blood chemistry, urinalysis, coagulation), AE and serious adverse event (SAE) monitoring. All participants will have a post-study safety follow-up contact conducted approximately 30 days after administration of study treatment. The study will be considered complete once all the participants have finished the required assessments, dropped out, or been lost to follow-up before completing the required assessments. The total study duration for each participant is expected to be up to maximum of 59 days, including the Screening period and the 30-day post-study safety contact follow up period.
