This study will evaluate the effect of food and smoking on healthy older subjects taking pomalidomide.

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:

  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).

  1. 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.

     * = True abstinence is acceptable when this is in line with the preferred and usual lifestyle of the subject. Period abstinence (e.g., calendar, ovulation, symptothermal, post ovulation methods) and withdrawal are not acceptable methods of contraception 9.Must agree to refrain from donating sperm or semen while participating in this study and for at least 28 days following the last dose of study drug.

     10.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 following the last dose of study drug.

     11.Must agree to comply with the conditions described in the counseling document (part of the pomalidomide Pregnancy Prevention Risk Management Plan.

     4. Cohort A subjects (smokers) must have a history of smoking for >5 years and currently smoke ≥1 pack (20-25) cigarettes per day; and urine cotinine level at screening and baseline (Day -1) indicate subject is heavy smoker.

     9. 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.
