POMALYST

Pomalidomide is a thalidomide analog. The chemical name is (RS)-4-Amino-2-(2,6-dioxo-piperidin-3-yl)-isoindoline-1,3-dione and it has the following chemical structure: The empirical formula for pomalidomide is C 13 H 11 N 3 O 4 and the gram molecular weight is 273.24. Pomalidomide is a yellow solid powder. It has limited to low solubility into organic solvents and it has low solubility in all pH solutions (about 0.01 mg/mL). Pomalidomide has a chiral carbon atom which exists as a racemic mixture of the R(+) and S(-) enantiomers. POMALYST is available in 1-mg, 2-mg, 3-mg, and 4-mg capsules for oral administration. Each capsule contains pomalidomide as the active ingredient and the following inactive ingredients: mannitol, pregelatinized starch, and sodium stearyl fumarate. The 1-mg capsule shell contains gelatin, titanium dioxide, FD&C blue 2, yellow iron oxide, white ink, and black ink. The 2-mg capsule shell contains gelatin, titanium dioxide, FD&C blue 2, yellow iron oxide, FD&C red 3, and white ink. The 3-mg capsule shell contains gelatin, titanium dioxide, FD&C blue 2, yellow iron oxide, and white ink. The 4-mg capsule shell contains gelatin, titanium dioxide, FD&C blue 1, FD&C blue 2, and white ink. pom-chem-structure

POMALYST is 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 POMALYST, in combination with dexamethasone, is 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 POMALYST is 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.

• Pregnancy ( 4.1 ) • Hypersensitivity ( 4.2 ) 4.1 Pregnancy POMALYST is contraindicated in females who are pregnant. POMALYST can cause fetal harm when administered to a pregnant female [see Warnings and Precautions (5.1) and Use in Specific Populations (8.1) ]. Pomalidomide is a thalidomide analogue and is teratogenic in both rats and rabbits when administered during the period of organogenesis. If the patient becomes pregnant while taking this drug, the patient should be apprised of the potential risk to a fetus. 4.2 Hypersensitivity POMALYST is contraindicated in patients who have demonstrated severe hypersensitivity (e.g., angioedema, anaphylaxis) to pomalidomide or any of the excipients [see Warnings and Precautions (5.7) , Description (11) ] .

Multiple Myeloma (MM) In Trial 1, data were evaluated from 219 patients (safety population) who received treatment with POMALYST + Low-dose Dex (112 patients) or POMALYST 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 POMALYST + Low-dose Dex (300 patients) or High-dose Dexamethasone (High-dose Dex) (150 patients). The median number of treatment cycles for the POMALYST + Low-dose Dex arm was 5. In the POMALYST + Low-dose Dex arm, 67% of patients had a dose interruption of POMALYST, the median time to the first dose interruption of POMALYST was 4.1 weeks. Twenty-seven percent of patients had a dose reduction of POMALYST, the median time to the first dose reduction of POMALYST was 4.5 weeks. Eight percent of patients discontinued POMALYST 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 POMALYST Treatment Arm in Trial 1* * Regardless of attribution of relatedness to POMALYST. a POMALYST alone arm includes all patients randomized to the POMALYST 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 POMALYST treatment arm.

Twenty-eight patients received POMALYST 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 POMALYST. 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 POMALYST. Dosage interruptions due to an adverse reaction occurred in 14% (4/28) of patients who received POMALYST. The most frequent adverse reaction requiring dosage interruption was decreased neutrophil count, which occurred in 3 patients. The POMALYST 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)

Strong CYP1A2 Inhibitors: Avoid concomitant use of strong CYP1A2 inhibitors. If concomitant use of a strong CYP1A2 inhibitor is unavoidable, reduce POMALYST dose to 2 mg ( 2.6 , 7.1 , 12.3 ). 7.1 Drugs That Affect Pomalidomide Plasma Concentrations CYP1A2 inhibitors : In healthy subjects, co-administration of fluvoxamine, a strong CYP1A2 inhibitor, increased C max and AUC of pomalidomide by 24% and 125% respectively [see Clinical Pharmacology (12.3) ] . Increased pomalidomide exposure may increase the risk of exposure related toxicities. Avoid co-administration of strong CYP1A2 inhibitors (e.g. ciprofloxacin and fluvoxamine) . If co-administration is unavoidable, reduce the POMALYST dose [see Dosage and Administration (2.6) ] .
