Food Effect and CYP1A2 Induction Study in Healthy Subjects

This study will be conducted in two parts. Parts 1 and 2 may be conducted in parallel and subjects are only allowed to participate in one part.

In Part 1, subjects will be randomly assigned to receive a single oral dose of 4 mg pomalidomide on Day 1 under fed (standard high fat breakfast) or fasted conditions. After a washout period of at least 3 and no more than 7 days, subjects will receive a single oral dose of 4 mg pomalidomide under the opposite condition to what they received in the first period.

In Part 2, healthy male smoker subjects must smoke approximately 20 cigarettes per day for a total of 10 days. Non-smokers will neither smoke nor be in the presence of smokers. All subjects will receive orally a 200-mg caffeine capsule on Day 6, and on Day 8, subjects will receive a single oral dose of 4 mg pomalidomide.

For both Parts 1 and 2, serial blood samples will be collected for determination of plasma pomalidomide concentrations.

Inclusion criteria

• Part 1: 1.Must understand and voluntarily sign a written Informed Consent prior to any study-related procedures being performed.

2.Must be able to communicate with the Investigator, understand and comply with the requirements of the study, and agree to adhere to restrictions and examination schedules.

3.Must be male or postmenopausal* women of any race between ≥61 to ≤85 years of age (inclusive) at the time of signing the Informed Consent, and in good health as determined by a physical exam, clinical laboratory safety test results, vital signs, and 12 lead Electrocardiogram.

• =Naturally postmenopausal for at least 24 consecutive months (ie, who has not had menses at any time in the preceding 24 consecutive months) 4.Subjects must be a non smoker. 5.Clinical laboratory tests must be within normal limits or acceptable to the Principal Investigator (PI).

6.Must have a normal or clinically acceptable 12-lead Electrocardiogram. 7.Must be afebrile (febrile is defined as ≥ 38.0ºC or 100.4 Fahrenheit), with supine systolic blood pressure (BP): 90 to 150 mmHg, supine diastolic blood pressure: 60 to 95 mmHg, and pulse rate: 40 to 110 bpm and controlled on medications if they are indicated (especially for blood pressure).

• If a subject has a diagnosis of hypertension, the range for BP and pulse rate will be the one that is considered well controlled on medication.

8.Must practice true abstinence* or agree to use a condom during sexual contact with a pregnant female or a female that can get pregnant while participating in the study, during dose interruptions and for at least 28 days following study drug discontinuation, even if he has undergone a successful vasectomy.
