1 INDICATIONS AND USAGE Pomalidomide capsules are a thalidomide analogue indicated for the treatment of adult patients: in combination with dexamethasone, for patients with multiple myeloma (MM) who have received at least two prior therapies including lenalidomide and a proteasome inhibitor and have demonstrated disease progression on or within 60 days of completion of the last therapy ( 1.1 ). with AIDS-related Kaposi sarcoma (KS) after failure of highly active antiretroviral therapy (HAART) or in patients with KS who are HIV-negative. This indication is approved under accelerated approval based on overall response rate. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s) ( 1.2 ). 1.1 Multiple Myeloma Pomalidomide, in combination with dexamethasone, are indicated for adult patients with multiple myeloma (MM) who have received at least two prior therapies including lenalidomide and a proteasome inhibitor and have demonstrated disease progression on or within 60 days of completion of the last therapy. 1.2 Kaposi Sarcoma Pomalidomide capsules are indicated for the treatment of: Adult patients with AIDS-related Kaposi sarcoma (KS) after failure of highly active antiretroviral therapy (HAART). Kaposi sarcoma (KS) in adult patients who are HIV-negative. This indication is approved under accelerated approval based on overall response rate [see Clinical Studies (14.2 )]. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s).

2 DOSAGE AND ADMINISTRATION MM: 4 mg per day taken orally on Days 1 through 21 of repeated 28-day cycles until disease progression ( 2.2 ). Refer to section 14.1 for dexamethasone dosing ( 14.1 ). KS: 5 mg per day taken orally on Days 1 through 21 of repeated 28-day cycles until disease progression or unacceptable toxicity ( 2.3 ).

Multiple Myeloma (MM) In Trial 1, data were evaluated from 219 patients (safety population) who received treatment with Pomalidomide + Low-dose Dex (112 patients) or pomalidomide alone (107 patients). Median number of treatment cycles was 5. Sixty-seven percent of patients in the study had a dose interruption of either drug due to adverse reactions. Forty-two percent of patients in the study had a dose reduction of either drug due to adverse reactions. The discontinuation rate due to adverse reactions was 11%. In Trial 2, data were evaluated from 450 patients (safety population) who received treatment with Pomalidomide + Low-dose Dex (300 patients) or High-dose Dexamethasone (High-dose Dex) (150 patients). The median number of treatment cycles for the Pomalidomide + Low-dose Dex arm was 5. In the Pomalidomide + Low-dose Dex arm, 67% of patients had a dose interruption of pomalidomide capsules, the median time to the first dose interruption of pomalidomide was 4.1 weeks. Twenty-seven percent of patients had a dose reduction of pomalidomide, the median time to the first dose reduction of pomalidomide was 4.5 weeks. Eight percent of patients discontinued pomalidomide due to adverse reactions. Tables 3 and 4 summarize the adverse reactions reported in Trials 1 and 2, respectively. Table 3: Adverse Reactions in Any Pomalidomide Capsules Treatment Arm in Trial 1* * Regardless of attribution of relatedness to pomalidomide. a Pomalidomide alone arm includes all patients randomized to the pomalidomide alone arm who took study drug; 61 of the 107 patients had dexamethasone added during the treatment period. b Serious adverse reactions were reported in at least 2 patients in any pomalidomide treatment arm.

Data cutoff: 01 March 2013 Other Adverse Reactions Other adverse reactions of pomalidomide capsules in patients with MM, not described above, and considered important: Cardiac Disorders : Myocardial infarction, Atrial fibrillation, Angina pectoris, Cardiac failure congestive Ear and Labyrinth Disorders : Vertigo Gastrointestinal disorders: Abdominal pain General Disorders and Administration Site Conditions: General physical health deterioration, Non-cardiac chest pain, Multi-organ failure Hepatobiliary Disorders: Hyperbilirubinemia Infections and Infestations: Pneumocystis jiroveci pneumonia, Respiratory syncytial virus infection, Neutropenic sepsis, Bacteremia, Pneumonia respiratory syncytial viral, Cellulitis, Urosepsis, Septic shock, Clostridium difficile colitis, Pneumonia streptococcal, Lobar pneumonia, Viral infection, Lung infection Investigations : Alanine aminotransferase increased, Hemoglobin decreased Injury, poisoning and procedural complications : Fall, Compression fracture, Spinal compression fracture Metabolism and nutritional disorders : Hyperkalemia, Failure to thrive Nervous system disorders : Depressed level of consciousness, Syncope Psychiatric disorders: Mental status change Renal and urinary disorders: Urinary retention, Hyponatremia Reproductive system and breast disorders: Pelvic pain Respiratory, thoracic, and mediastinal disorders: Interstitial lung disease, Pulmonary embolism, Respiratory failure, Bronchospasm Vascular disorders : Hypotension 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. Tables 5 and 6 summarize the adverse reactions and select laboratory abnormalities reported in Trial 12-C-0047.

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Blood and Lymphatic System Disorders: Pancytopenia Endocrine Disorders : Hypothyroidism, hyperthyroidism Gastrointestinal Disorders: Gastrointestinal hemorrhage Hepatobiliary Disorders: Hepatic failure (including fatal cases), elevated liver enzymes Immune system Disorders: Allergic reactions (e.g., angioedema, anaphylaxis, urticaria), solid organ transplant rejection Infections and Infestations : Hepatitis B virus reactivation, Herpes zoster, progressive multifocal leukoencephalopathy (PML) Neoplasms benign, malignant and unspecified (incl cysts and polyps): Tumor lysis syndrome, basal cell carcinoma, and squamous cell carcinoma of the skin Skin and Subcutaneous Tissue Disorders: Stevens-Johnson Syndrome, toxic epidermal necrolysis, drug reaction with eosinophilia and systemic symptoms (DRESS)

12.3 Pharmacokinetics In patients with MM who received pomalidomide 4 mg daily alone or in combination with dexamethasone, pomalidomide steady-state drug exposure was characterized by AUC (CV%) of 860 (37%) ng∙h/mL and C max (CV%) of 75 (32%) ng/mL. In patients with Kaposi sarcoma (KS) who received pomalidomide 5 mg daily, pomalidomide steady-state drug exposure was characterized by AUC of 462.3 ng∙h/mL (82%) and C max of 53.1 ng/mL (50%). Absorption Following administration of single oral doses of pomalidomide, the maximum plasma concentration (C max ) for pomalidomide occurs at 2 to 3 hours postdose in patients with MM or KS. Effect of Food Co-administration of pomalidomide capsules with a high-fat meal (approximately 50% of the total caloric content) and high-calorie meal (approximately 800 to 1000 calories) (the meal contained approximately 150, 250, and 500 to 600 calories from protein, carbohydrates, and fat, respectively) delays the T max by 2.5 hours, decreased mean plasma C max and AUC in healthy subjects by about 27% and 8%, respectively. Distribution Pomalidomide has a mean apparent volume of distribution (Vd/F) between 62 and 138 L at steady state in patients with MM or KS. Pomalidomide is distributed in semen of healthy subjects at a concentration of approximately 67% of plasma level at 4 hours postdose (~T max ) after 4 days of 2 mg once-daily dosing. Human plasma protein binding of pomalidomide ranges from 12% to 44% and is not concentration dependent. Pomalidomide is a substrate for P-gp. Elimination Pomalidomide has a mean total body clearance (CL/F) of 7-10 L/h in patients with MM or KS. Pomalidomide is eliminated with a median plasma half-life of 9.5 hours in healthy subjects and 7.5 hours in patients with MM or KS. Metabolism Pomalidomide is primarily metabolized in the liver by CYP1A2 and CYP3A4. Minor contributions from CYP2C19 and CYP2D6 were also observed in vitro. Excretion Following a single oral administration of [ 14 C]-pomalidomide to healthy subjects, approximately 73% and 15% of the radioactive dose was eliminated in urine and feces, respectively, with approximately 2% and 8% of the radiolabeled dose eliminated unchanged as pomalidomide in urine and feces. Specific Populations Age (61 to 85 years old), sex and race have no clinically significant effect on the systemic exposure of pomalidomide. Patients with Renal Impairment Pomalidomide pharmacokinetic parameters were not significantly affected in patients with moderate (30 mL/min ≤ CLcr< 60 mL/min) or severe (15 mL/min ≤ CLcr< 30 mL/min) renal impairment relative to patients with normal renal function (CLcr ≥ 60 mL/min). Mean exposure (AUC) to pomalidomide increased by 38% in patients with severe renal impairment requiring dialysis (CLcr< 30 mL/min requiring dialysis) and 40% in patients with end stage renal disease (CLcr< 15 mL/min) on non-dialysis days. In patients with severe renal impairment requiring dialysis, the estimated dialysis clearance is approximately 12 L/h which is higher than pomalidomide total body clearance, indicating hemodialysis will remove pomalidomide from the blood circulation. Patients with Hepatic Impairment Mean exposure (AUC) of pomalidomide increased by 51%, 58% and 72% in subjects with mild, moderate or severe hepatic impairment as defined by Child-Pugh criteria, respectively. Drug Interaction Studies Clinical Studies Co-administration of pomalidomide with the following drugs did not increase pomalidomide exposure to a clinically significant extent: ketoconazole (a strong CYP3A4 and P-gp inhibitor), carbamazepine (a strong CYP3A4 inducer) and dexamethasone (a weak to moderate CYP3A4 inducer). Co-administration of pomalidomide capsules with drugs that are CYP1A2 inducers has not been studied. CYP1A2 Inhibitors: Co-administration of fluvoxamine (a strong CYP1A2 inhibitor) with pomalidomide increased mean [90% confidence interval] pomalidomide exposure by 125% [98% to 157%] compared to pomalidomide alone in healthy subjects. Co-administration of fluvoxamine in the presence of ketoconazole (a strong CYP3A4 and P-gp inhibitor) with pomalidomide increased mean pomalidomide exposure by 146% [126% to 167%] compared to pomalidomide administered alone in healthy subjects, indicating the predominant effect of CYP1A2 inhibition in the increase of pomalidomide exposure [see Dosage and Administration (2.6) and Drug Interactions (7.1 )]. Strong CYP3A4 and P-gp Inhibitors: Co-administration of ketoconazole (a strong CYP3A4 and P-gp inhibitor) in 16 healthy male subjects increased AUC of pomalidomide by 19% compared to pomalidomide administered alone. Strong CYP1A2 Inducers: Co-administration of pomalidomide capsules with drugs that are CYP1A2 inducers has not been studied and may reduce pomalidomide exposure. Strong CYP3A4 Inducers: Co-administration of carbamazepine to 16 healthy male subjects decreased AUC of pomalidomide by 20% with a 90% confidence interval [13% to 27%] compared to when pomalidomide was administered alone. Dexamethasone: Co-administration of multiple doses of 4 mg pomalidomide capsules with 20 mg to 40 mg dexamethasone (a weak to moderate inducer of CYP3A4) to patients with MM had no effect on thepharmacokinetics of pomalidomide compared to when pomalidomide was administered alone. Smoking: In 14 healthy male subjects who smoked 25 cigarettes per day for a total of 10 days, after single oral dose of 4 mg pomalidomide capsules, C max of pomalidomide increased 14% while AUC of pomalidomide decreased 32%, compared to that in 13 healthy male subjects who were non-smokers. In Vitro Studies Pomalidomide does not inhibit or induce cytochrome p450 enzymes or transporters in vitro.
