A Phase 1 Open-Label Study to Evaluate the Effect of CYP450 and P-gp Inhibition and Induction on the Pharmacokinetics of Pomalidomide (CC-4047) in Healthy Male Subjects — DDI  

Healthy Clinical Trial

Official title: A Phase 1 Open-Label Study to Evaluate the Effect of CYP450 and P-gp Inhibition and Induction on the Pharmacokinetics of Pomalidomide (CC-4047) in Healthy Male Subjects

Status Completed

Clinical Trial Summary

1. To evaluate the pharmacokinetics (PK) of pomalidomide administered with the CYP3A4/P-gp inhibitor ketoconazole compared with pomalidomide alone in healthy male subjects.

2. To evaluate the PK of pomalidomide administered with the CYP3A4/P-gp inhibitor ketoconazole plus the CYP1A2 inhibitor fluvoxamine compared with pomalidomide alone in healthy male subjects.

3. To assess the PK of pomalidomide administered with the CYP1A2 inhibitor fluvoxamine and the CYP3A4/P-gp inhibitor ketoconazole compared with pomalidomide plus the CYP3A4/P-gp inhibitor ketoconazole in healthy male subjects.

Part 2

1) To evaluate the pharmacokinetics of pomalidomide administered with the CYP3A4 inducer carbamazepine compared with pomalidomide alone in healthy male volunteers.

Secondary Objectives

1) To evaluate the safety of pomalidomide in Part 1 and Part 2 when administered with ketoconazole, fluvoxamine and/or carbamazepine.

In addition: To evaluate the safety of pomalidomide in Part 1 and Part 2 when administered with ketoconazole, fluvoxamine and/or carbamazepine.

Clinical Trial Description

This will be a single-center, open label non randomized, 2-part study with 3 periods in Part 1, and 2 periods in Part 2. Parts 1 and 2 will be conducted in parallel. The entire study will consist of a screening phase, two dosing parts, and a follow-up telephone call for safety. All Periods will be separated by a washout period of at least 3 days (no more than 5 days) from the last pomalidomide dose to the next drug dose.

Safety will be monitored throughout the study. Safety evaluations will include adverse event (AE) reporting, concomitant medications, PEs, vital sign measurements, 12-lead ECGs, and clinical laboratory safety tests.

Thirty-two healthy (16 per each Part), male adult subjects 18 to 55 years of age who meet all inclusion criteria and do not meet any of the exclusion criteria will be enrolled in the study. Subjects enrolled in Part 1 cannot participate in Part 2 and vice versa.

Study treatments (pomalidomide, ketoconazole, fluvoxamine and carbamazepine) should be administered with meals and subjects should be a served a standard meal (ie, breakfast or dinner) approximately 30 minutes prior to dosing. The meal should be consumed within 30 minutes from serving and dosing must occur 30 minutes (±5 minutes) after serving the meal. Subjects should be encouraged to consume the whole meal served prior to dosing. After each dosing, food and beverages (except water) will be withheld from all subjects until at least 4 hours post dose; thereafter, subjects will be served standard meals and snacks.

For determination of plasma concentrations of pomalidomide, ketoconazole, fluvoxamine and carbamazepine (and its active metabolite carbamazepine 10,11-epoxide) in each dosing regimen (Period), serial blood samples will be collected.

A safety follow-up will be conducted by telephone within 4 to 7 days from the last dose. In the event a subject discontinues from the study prematurely, an early termination visit will be performed within 4 days following the day of discontinuation. ;
