Kaposi Sarcoma (KS)
The safety of pomalidomide capsules in patients with KS was evaluated in Trial 12-C-0047 [see Clinical Studies (14.2)]. Twenty-eight patients received pomalidomide capsules 5 mg taken orally once daily on Days 1 through 21 of repeated 28- day cycles. The study excluded patients with procoagulant disorders or a history of venous or arterial thromboembolism. Patients received DVT prophylaxis with daily low dose aspirin. Across all patients treated on Trial 12-C-0047, 75% were exposed to pomalidomide for 6 months or longer and 25% were exposed for greater than one year.
Serious adverse reactions occurred in 18% (5/28) of patients who received pomalidomide capsules. The following serious adverse reactions each occurred in 1 patient: anemia, decreased neutrophil count, and hematuria.
Permanent discontinuation due to an adverse reaction occurred in 11% (3/28) of patients who received pomalidomide capsules.
Dosage interruptions due to an adverse reaction occurred in 14% (4/28) of patients who received pomalidomide capsules. The most frequent adverse reaction requiring dosage interruption was decreased neutrophil count, which occurred in 3 patients.
The pomalidomide capsules dose was reduced due to an adverse reaction in 1 patient due to gout.

Table 10 summarizes the progression free survival (PFS) and overall response rate (ORR) based on the assessment by the Independent Review Adjudication Committee (IRAC) review at the final PFS analysis and overall survival (OS) at the OS analysis. PFS was significantly longer with pomalidomide capsules + Low-dose Dex than High-dose Dex: HR 0.45 (95% CI: 0.35-0.59 p < 0.001). OS was also significantly longer with pomalidomide capsules + Low-dose Dex than High-dose Dex: HR 0.70 (95% CI: 0.54-0.92 p = 0.009). The Kaplan-Meier curves for PFS and OS for the ITT population are provided in Figures 1 and 2, respectively.

MEDICATION GUIDE
Pomalidomide (poe˝-ma-lid’-oh-mide) capsules
What is the most important information I should know about pomalidomide capsules?
Before you begin taking pomalidomide capsules, you must read and agree to all of the instructions in PS-Pomalidomide REMS. For more information, call 1-888-423-5436 or go to www.PS-PomalidomideREMS.com. Before prescribing pomalidomide capsules, your healthcare provider will explain PS-
Pomalidomide REMS to you and have you sign the Patient-Physician Agreement Form.
Pomalidomide capsules can cause serious side effects including:
- Possible birth defects (deformed babies) or death of an unborn baby. Females who are pregnant or who plan to become pregnant must not take pomalidomide capsules.
Pomalidomide capsules are similar to the medicine thalidomide (THALOMID). We know thalidomide can cause severe life- threatening birth defects. Pomalidomide capsules have not been tested in pregnant females. Pomalidomide capsules have harmed unborn animals in animal testing.
Females must not get pregnant:
- For at least 4 weeks before starting pomalidomide capsules
- While taking pomalidomide capsules
- During any breaks (interruptions) in your treatment with pomalidomide capsules
- For at least 4 weeks after stopping pomalidomide capsules
Females who can become pregnant:
- Will have pregnancy tests weekly for 4 weeks, then every 4 weeks if your menstrual cycle is regular, or every 2 weeks if your menstrual cycle is irregular.
If you miss your period or have unusual bleeding, you will need to have a pregnancy test and receive counseling.
- Must agree to use two acceptable forms of birth control at the same time, for at least 4 weeks before, while taking, during any breaks (interruptions) in your treatment, and for at least 4 weeks after stopping pomalidomide capsules.
- Talk with your healthcare provider to find out about options for acceptable forms of birth control that you may use to prevent pregnancy before, during, and after treatment with pomalidomide capsules.
If you become pregnant while taking pomalidomide capsules, stop taking it right away and call your healthcare provider. If your healthcare provider is not available, you can call the REMS Call Center at 1-888-423-5436.
Healthcare providers and patients should report all cases of pregnancy to:
- FDA MedWatch at 1-800-FDA-1088, and
- REMS Call Center at 1-888-423-5436
There is a pregnancy exposure registry that monitors the outcomes of females who take pomalidomide capsules during pregnancy, or if their male partner takes pomalidomide capsules and they are exposed during pregnancy. You can enroll in this registry by calling the REMS Call Center at the phone number listed above.
Pomalidomide can pass into human semen:
- Males, including those who have had a vasectomy, must always use a latex or synthetic condom during any sexual contact with a pregnant female or a female that can become pregnant while taking pomalidomide capsules, during any breaks (interruptions) in your treatment with pomalidomide capsules, and for 4 weeks after stopping pomalidomide capsules.
- Do not have unprotected sexual contact with a female who is or could become pregnant. Tell your healthcare provider if you do have unprotected sexual contact with a female who is or could become pregnant.
- Do not donate sperm while taking pomalidomide capsules, during any breaks (interruptions) in your treatment, and for 4 weeks after stopping pomalidomide capsules. If a female becomes pregnant with your sperm, the baby may be exposed to pomalidomide capsules and may be born with birth defects.
Men, if your female partner becomes pregnant, you should call your healthcare provider right away.
