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
• Trial end date: 2012-11-01
• Target enrollment: 0
• Participant gender: Male

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.

5. Clinical laboratory safety tests must be within normal limits or clinically acceptable to the Principal investigator (PI)

• Subjects (with or without vasectomy) must agree to use barrier contraception (ie, latex condom or any non-latex condom not made out of natural [animal] membrane [eg, polyurethane]) and one other method (eg, spermicide) when engaging in sexual activity with woman of child-bearing potential during study conduct, and for 90 days after the last dose of study medication.

• Must agree to refrain from donating blood or plasma (other than for this study) while participating in this study and for at least 28 days after the last dose of study drug.

• Similarly, must agree to refrain from donating sperm while participating in this study and for at least 90 days after the last dose of study drug.
