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.

1 INDICATIONS AND USAGE 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. 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).

10 OVERDOSAGE Hemodialysis can remove pomalidomide from circulation.

7 DRUG INTERACTIONS 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) ] .

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Pomalidomide is an analogue of thalidomide with immunomodulatory, antiangiogenic, and antineoplastic properties. Cellular activities of pomalidomide are mediated through its target cereblon, a component of a cullin ring E3 ubiquitin ligase enzyme complex. In vitro, in the presence of drug, substrate proteins (including Aiolos and Ikaros) are targeted for ubiquitination and subsequent degradation leading to direct cytotoxic and immunomodulatory effects. In in vitro cellular assays, pomalidomide inhibited proliferation and induced apoptosis of hematopoietic tumor cells. Additionally, pomalidomide inhibited the proliferation of lenalidomide-resistant multiple myeloma (MM) cell lines and synergized with dexamethasone in both lenalidomide-sensitive and lenalidomide-resistant cell lines to induce tumor cell apoptosis. Pomalidomide enhanced T cell- and natural killer (NK) cell-mediated immunity and inhibited production of pro-inflammatory cytokines (e.g., TNF-α and IL-6) by monocytes. Pomalidomide demonstrated anti-angiogenic activity in a mouse tumor model and in the in vitro umbilical cord model. 12.2 Pharmacodynamics Pomalidomide exposure-response analyses showed that there was no relationship between systemic pomalidomide exposure level and efficacy or safety following pomalidomide dose of 4 mg. Cardiac Electrophysiology The QTc prolongation potential of pomalidomide was evaluated in a single center, randomized, double-blind crossover study (N=72) using 4 mg pomalidomide, 20 mg pomalidomide, placebo, and 400 mg moxifloxacin (positive control). No significant QTc prolongation effect of pomalidomide was observed following pomalidomide doses of 4 and 20 mg. 12.3 Pharmacokinetics In patients with MM who received POMALYST 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 POMALYST 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 POMALYST, 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 POMALYST 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 POMALYST 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 POMALYST with drugs that are CYP1A2 inducers has not been studied. CYP1A2 Inhibitors: Co-administration of fluvoxamine (a strong CYP1A2 inhibitor) with POMALYST increased mean [90% confidence interval] pomalidomide exposure by 125% [98% to 157%] compared to POMALYST alone in healthy subjects. Co-administration of fluvoxamine in the presence of ketoconazole (a strong CYP3A4 and P-gp inhibitor) with POMALYST increased mean pomalidomide exposure by 146% [126% to 167%] compared to POMALYST 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 POMALYST administered alone. Strong CYP1A2 Inducers: Co-administration of POMALYST 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 POMALYST with 20 mg to 40 mg dexamethasone (a weak to moderate inducer of CYP3A4) to patients with MM had no effect on the pharmacokinetics 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 POMALYST, 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 .

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Studies examining the carcinogenic potential of pomalidomide have not been conducted. One of 12 monkeys dosed with 1 mg/kg of pomalidomide (an exposure approximately 15-fold of the exposure in patients at the recommended dose of 4 mg/day) developed acute myeloid leukemia in a 9-month repeat-dose toxicology study. Pomalidomide was not mutagenic or clastogenic in a battery of tests, including the bacteria reverse mutation assay (Ames test), the in vitro assay using human peripheral blood lymphocytes, and the micronucleus test in orally treated rats administered doses up to 2000 mg/kg/day. In a fertility and early embryonic development study in rats, drug-treated males were mated with untreated or treated females. Pomalidomide was administered to males and females at doses of 25 to 1000 mg/kg/day. When treated males were mated with treated females, there was an increase in post-implantation loss and a decrease in mean number of viable embryos at all dose levels. There were no other effects on reproductive functions or the number of pregnancies. The lowest dose tested in animals resulted in an exposure (AUC) approximately 100-fold of the exposure in patients at the recommended dose of 4 mg/day. When treated males in this study were mated with untreated females, all uterine parameters were comparable to the controls. Based on these results, the observed effects were attributed to the treatment of females.

This Medication Guide has been approved by the U.S. Food and Drug Administration. Revised: March 2023 MEDICATION GUIDE POMALYST ® (POM-uh-list) (pomalidomide) capsules What is the most important information I should know about POMALYST? Before you begin taking POMALYST, you must read and agree to all of the instructions in the POMALYST REMS ® program. For more information, call 1-888-423-5436 or go to www.pomalystrems.com. Before prescribing POMALYST, your healthcare provider will explain the POMALYST REMS program to you and have you sign the Patient-Physician Agreement Form. POMALYST 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 POMALYST. POMALYST is similar to the medicine thalidomide (THALOMID). We know thalidomide can cause severe life-threatening birth defects. POMALYST has not been tested in pregnant females. POMALYST has harmed unborn animals in animal testing. Females must not get pregnant: o For at least 4 weeks before starting POMALYST o While taking POMALYST o During any breaks (interruptions) in your treatment with POMALYST o For at least 4 weeks after stopping POMALYST Females who can become pregnant: o 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. o 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 POMALYST. o 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 POMALYST. If you become pregnant while taking POMALYST, 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: o FDA MedWatch at 1-800-FDA-1088, and o REMS Call Center at 1-888-423-5436 There is a pregnancy exposure registry that monitors the outcomes of females who take POMALYST during pregnancy, or if their male partner takes POMALYST and they are exposed during pregnancy. You can enroll in this registry by calling the REMS Call Center at the phone number listed above. POMALYST can pass into human semen: o 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 POMALYST, during any breaks (interruptions) in your treatment with POMALYST, and for 4 weeks after stopping POMALYST. o 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. o Do not donate sperm while taking POMALYST, during any breaks (interruptions) in your treatment, and for 4 weeks after stopping POMALYST. If a female becomes pregnant with your sperm, the baby may be exposed to POMALYST and may be born with birth defects. Men, if your female partner becomes pregnant, you should call your healthcare provider right away. • Blood clots in your arteries, veins, and lungs, heart attack, and stroke can happen if you take POMALYST. Most people who take POMALYST will also take a blood thinner medicine to help prevent blood clots. Before taking POMALYST, tell your healthcare provider: o If you have had a blood clot in the past o If you have high blood pressure, smoke, or if you have been told you have a high level of fat in your blood (hyperlipidemia) o About all the medicines you take. Certain other medicines can also increase your risk for blood clots Call your healthcare provider or get medical help right away if you get any of the following during treatment with POMALYST: • Signs or symptoms of a blood clot in the lung, arm, or leg may include : shortness of breath, chest pain, or arm or leg swelling • Signs or symptoms of a heart attack may include : chest pain that may spread to the arms, neck, jaw, back, or stomach area (abdomen), feeling sweaty, shortness of breath, feeling sick or vomiting • Signs or symptoms of stroke may include: sudden numbness or weakness, especially on one side of the body, severe headache or confusion, or problems with vision, speech, or balance. What is POMALYST? POMALYST is a prescription medicine used to treat adults with: • Multiple myeloma. POMALYST is taken along with the medicine dexamethasone, in people who: o have received at least 2 prior medicines to treat multiple myeloma, including a type of medicine known as a proteasome inhibitor and lenalidomide, and o their disease has become worse during treatment or within 60 days of finishing the last treatment • AIDS-related Kaposi sarcoma (KS). POMALYST is taken when highly active antiretroviral therapy (HAART) has not worked well enough or stopped working (failed) • KS who do not have HIV infection (HIV negative). It is not known if POMALYST is safe and effective in children. Who should not take POMALYST? Do not take POMALYST if you: • are pregnant, plan to become pregnant, or become pregnant during treatment with POMALYST. See "What is the most important information I should know about POMALYST?" • are allergic to pomalidomide or any of the ingredients in POMALYST. See the end of this Medication Guide for a complete list of ingredients in POMALYST. What should I tell my healthcare provider before taking POMALYST? Before you take POMALYST, tell your healthcare provider if you: • smoke cigarettes. POMALYST may not work as well in people who smoke • have liver problems • have kidney problems and are receiving hemodialysis treatment • have any other medical conditions • are breastfeeding. You should not breastfeed during treatment with POMALYST. It is not known if POMALYST passes into your breast milk and can harm your baby. Tell your healthcare provider about all the medicines you take , including prescription and over-the-counter medicines, vitamins, and herbal supplements. POMALYST and other medicines may affect each other, causing serious side effects. Talk with your healthcare provider before taking any new medicines. Know the medicines you take.

14 CLINICAL STUDIES 14.1 Multiple Myeloma Trial 1 Trial 1 was a phase 2, multicenter, randomized open-label study in patients with relapsed multiple myeloma (MM) who were refractory to their last myeloma therapy and had received lenalidomide and bortezomib. Patients were considered relapsed if they had achieved at least stable disease for at least 1 cycle of treatment to at least 1 prior regimen and then developed progressive disease. Patients were considered refractory if they experienced disease progression on or within 60 days of their last therapy. A total of 221 patients were randomized to receive POMALYST alone or POMALYST with Low-dose Dex. In Trial 1, the safety and efficacy of POMALYST 4 mg, once daily for 21 of 28 days, until disease progression, were evaluated alone and in combination with Low-dose Dex (40 mg/day given only on Days 1, 8, 15, and 22 of each 28-day cycle for patients aged 75 years or younger, or 20 mg/day given only on Days 1, 8, 15, and 22 of each 28-day cycle for patients aged greater than 75 years). Patients in the POMALYST alone arm were allowed to add Low-dose Dex upon disease progression. Table 7 summarizes the baseline patient and disease characteristics in Trial 1. The baseline demographics and disease characteristics were balanced and comparable between the study arms.

Patients with creatinine clearance ≥ 45mL/min qualified for the trial. A total of 455 patients were enrolled in the trial: 302 in the POMALYST + Low-dose Dex arm and 153 in the High-dose Dex arm. Patients in the POMALYST + Low-dose Dex arm were administered 4 mg POMALYST orally on Days 1 to 21 of each 28-day cycle. Dexamethasone (40 mg) was administered once per day on Days 1, 8, 15 and 22 of a 28-day cycle. Patients > 75 years of age started treatment with 20 mg dexamethasone using the same schedule. For the High-dose Dex arm, dexamethasone (40 mg) was administered once per day on Days 1 through 4, 9 through 12, and 17 through 20 of a 28-day cycle. Patients > 75 years of age started treatment with 20 mg dexamethasone using the same schedule. Treatment continued until patients had disease progression. Baseline patient and disease characteristics were balanced and comparable between the study arms, as summarized in Table 9. Overall, 94% of patients had disease refractory to lenalidomide, 79% had disease refractory to bortezomib and 74% had disease refractory to both lenalidomide and bortezomib.

A total of 28 patients (18 HIV-positive, 10 HIV-negative) received POMALYST 5 mg orally once daily on Days 1 through 21 of each 28-day cycle until disease progression or unacceptable toxicity. All HIV-positive patients continued highly active antiretroviral therapy (HAART). The trial excluded patients with symptomatic pulmonary or visceral KS, history of venous or arterial thromboembolism, or procoagulant disorders. Patients received thromboprophylaxis with aspirin 81 mg once daily throughout therapy. The median age was 52.5 years, all were male, 75% were White, and 14% Black or African American. Seventy-five percent of patients had advanced disease (T1) at the time of enrollment, 11% had ≥ 50 lesions, and 75% had received prior chemotherapy. The major efficacy outcome measure was overall response rate (ORR), which included complete response (CR), clinical complete response (cCR), and partial response (PR). Response was assessed by the investigator according to the AIDS Clinical Trial Group (ACTG) Oncology Committee response criteria for KS. The median time to first response was 1.8 months (0.9 to 7.6). Efficacy results are presented in Table 11.

8.5 Geriatric Use Multiple Myeloma Of the total number of patients in clinical studies of POMALYST, 44% were aged older than 65 years, while 10% were aged older than 75 years. No overall differences in effectiveness were observed between these patients and younger patients. In these studies, patients older than 65 years were more likely than patients less than or equal to 65 years of age to experience pneumonia. Kaposi Sarcoma Of the 28 patients who received POMALYST, 11% were 65 years or older, and 3.6% were 75 years of age or older. The clinical study did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger patients.

8.4 Pediatric Use The safety and effectiveness of POMALYST have not been established in pediatric patients. The safety and effectiveness were assessed but not established in two open-label studies: a dose escalation study in 25 pediatric patients aged 5 to <17 with recurrent, progressive or refractory CNS tumors [NCT02415153] and a parallel-group study conducted in 47 pediatric patients aged 4 to <17 years with recurrent or progressive high-grade glioma, medulloblastoma, ependymoma, or diffuse intrinsic pontine glioma (DIPG) [NCT03257631]. No new safety signals were observed in pediatric patients across these studies. At the same dose by body surface area, pomalidomide exposure in 55 pediatric patients aged 4 to < 17 years old was within the range observed in adult patients with MM but higher than the exposure observed in adult patients with KS [see Clinical Pharmacology (12.3) ] .

8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in females exposed to POMALYST during pregnancy as well as female partners of male patients who are exposed to POMALYST. This registry is also used to understand the root cause for the pregnancy. Report any suspected fetal exposure to POMALYST to the FDA via the MedWatch program at 1-800-FDA-1088 and also to the REMS Call Center at 1-888-423-5436. Risk Summary Based on the mechanism of action [see Clinical Pharmacology (12.1) ] and findings from animal studies, POMALYST can cause embryo-fetal harm when administered to a pregnant female and is contraindicated during pregnancy [see Contraindications (4) , and Warnings and Precautions (5.1) ] . POMALYST is a thalidomide analogue. Thalidomide is a human teratogen, inducing a high frequency of severe and life-threatening birth defects such as amelia (absence of limbs), phocomelia (short limbs), hypoplasticity of the bones, absence of bones, external ear abnormalities (including anotia, micropinna, small or absent external auditory canals), facial palsy, eye abnormalities (anophthalmos, microphthalmos), and congenital heart defects. Alimentary tract, urinary tract, and genital malformations have also been documented, and mortality at or shortly after birth has been reported in about 40% of infants. Pomalidomide was teratogenic in both rats and rabbits when administered during the period of organogenesis. Pomalidomide crossed the placenta after administration to pregnant rabbits (see Data ) . If this drug is used during pregnancy or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential risk to a fetus. If pregnancy does occur during treatment, immediately discontinue the drug. Under these conditions, refer patient to an obstetrician/gynecologist experienced in reproductive toxicity for further evaluation and counseling. Report any suspected fetal exposure to POMALYST to the FDA via the MedWatch program at 1-800-FDA-1088 and also to the REMS Call Center at 1-888-423-5436. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. The estimated background risk in the U.S. general population of major birth defects is 2%-4% and of miscarriage is 15%-20% of clinically recognized pregnancies. Data Animal Data Pomalidomide was teratogenic in both rats and rabbits in the embryo-fetal developmental studies when administered during the period of organogenesis. In rats, pomalidomide was administered orally to pregnant animals at doses of 25 to 1000 mg/kg/day. Malformations or absence of urinary bladder, absence of thyroid gland, and fusion and misalignment of lumbar and thoracic vertebral elements (vertebral, central, and/or neural arches) were observed at all dose levels. There was no maternal toxicity observed in this study. The lowest dose in rats resulted in an exposure (AUC) approximately 85-fold of the human exposure at the recommended dose of 4 mg/day. Other embryo-fetal toxicities included increased resorptions leading to decreased number of viable fetuses. In rabbits, pomalidomide was administered orally to pregnant animals at doses of 10 to 250 mg/kg/day. Increased cardiac malformations such as interventricular septal defect were seen at all doses with significant increases at 250 mg/kg/day. Additional malformations observed at 250 mg/kg/day included anomalies in limbs (flexed and/or rotated fore- and/or hindlimbs, unattached or absent digit) and associated skeletal malformations (not ossified metacarpal, misaligned phalanx and metacarpal, absent digit, not ossified phalanx, and short not ossified or bent tibia), moderate dilation of the lateral ventricle in the brain, abnormal placement of the right subclavian artery, absent intermediate lobe in the lungs, low-set kidney, altered liver morphology, incompletely or not ossified pelvis, an increased average for supernumerary thoracic ribs, and a reduced average for ossified tarsals. No maternal toxicity was observed at the low dose (10 mg/kg/day) that resulted in cardiac anomalies in fetuses; this dose resulted in an exposure (AUC) approximately equal to that reported in humans at the recommended dose of 4 mg/day. Additional embryo-fetal toxicity included increased resorption. Following daily oral administration of pomalidomide from Gestation Day 7 through Gestation Day 20 in pregnant rabbits, fetal plasma pomalidomide concentrations were approximately 50% of the maternal C max at all dosages (5 to 250 mg/kg/day), indicating that pomalidomide crossed the placenta.

8 USE IN SPECIFIC POPULATIONS • Lactation: Advise women not to breastfeed ( 8.2 ). 8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in females exposed to POMALYST during pregnancy as well as female partners of male patients who are exposed to POMALYST. This registry is also used to understand the root cause for the pregnancy.

Additional embryo-fetal toxicity included increased resorption. Following daily oral administration of pomalidomide from Gestation Day 7 through Gestation Day 20 in pregnant rabbits, fetal plasma pomalidomide concentrations were approximately 50% of the maternal C max at all dosages (5 to 250 mg/kg/day), indicating that pomalidomide crossed the placenta. 8.2 Lactation Risk Summary There is no information regarding the presence of pomalidomide in human milk, the effects of POMALYST on the breastfed child, or the effects of POMALYST on milk production. Pomalidomide was excreted in the milk of lactating rats (see Data ) . Because many drugs are excreted in human milk and because of the potential for adverse reactions in a breastfed child from POMALYST, advise women not to breastfeed during treatment with POMALYST. Data Animal Data Following a single oral administration of pomalidomide to lactating rats approximately 14 days postpartum, pomalidomide was transferred into milk, with milk to plasma ratios of 0.63 to 1.46. 8.3 Females and Males of Reproductive Potential Pregnancy Testing POMALYST can cause fetal harm when administered during pregnancy [see Use in Specific Populations (8.1) ]. Verify the pregnancy status of females of reproductive potential prior to initiating POMALYST therapy and during therapy. Advise females of reproductive potential that they must avoid pregnancy 4 weeks before therapy, while taking POMALYST, during dose interruptions and for at least 4 weeks after completing therapy. Females of reproductive potential must have 2 negative pregnancy tests before initiating POMALYST. The first test should be performed within 10-14 days, and the second test within 24 hours prior to prescribing POMALYST. Once treatment has started and during dose interruptions, pregnancy testing for females of reproductive potential should occur weekly during the first 4 weeks of use, then pregnancy testing should be repeated every 4 weeks in females with regular menstrual cycles. If menstrual cycles are irregular, the pregnancy testing should occur every 2 weeks. Pregnancy testing and counseling should be performed if a patient misses her period or if there is any abnormality in her menstrual bleeding. POMALYST treatment must be discontinued during this evaluation. Contraception Females Females of reproductive potential must commit either to abstain continuously from heterosexual sexual intercourse or to use 2 methods of reliable birth control simultaneously: one highly effective form of contraception – tubal ligation, IUD, hormonal (birth control pills, injections, hormonal patches, vaginal rings, or implants), or partner's vasectomy, and 1 additional effective contraceptive method – male latex or synthetic condom, diaphragm, or cervical cap. Contraception must begin 4 weeks prior to initiating treatment with POMALYST, during therapy, during dose interruptions, and continuing for 4 weeks following discontinuation of POMALYST therapy. Reliable contraception is indicated even where there has been a history of infertility, unless due to hysterectomy. Females of reproductive potential should be referred to a qualified provider of contraceptive methods, if needed. Males Pomalidomide is present in the semen of males who take POMALYST. Therefore, males must always use a latex or synthetic condom during any sexual contact with females of reproductive potential while taking POMALYST and for up to 4 weeks after discontinuing POMALYST, even if they have undergone a successful vasectomy. Male patients taking POMALYST must not donate sperm. Infertility Based on findings in animals, female fertility may be compromised by treatment with POMALYST [see Nonclinical Toxicology (13.1) ] . 8.4 Pediatric Use The safety and effectiveness of POMALYST have not been established in pediatric patients. The safety and effectiveness were assessed but not established in two open-label studies: a dose escalation study in 25 pediatric patients aged 5 to <17 with recurrent, progressive or refractory CNS tumors [NCT02415153] and a parallel-group study conducted in 47 pediatric patients aged 4 to <17 years with recurrent or progressive high-grade glioma, medulloblastoma, ependymoma, or diffuse intrinsic pontine glioma (DIPG) [NCT03257631]. No new safety signals were observed in pediatric patients across these studies. At the same dose by body surface area, pomalidomide exposure in 55 pediatric patients aged 4 to < 17 years old was within the range observed in adult patients with MM but higher than the exposure observed in adult patients with KS [see Clinical Pharmacology (12.3) ] . 8.5 Geriatric Use Multiple Myeloma Of the total number of patients in clinical studies of POMALYST, 44% were aged older than 65 years, while 10% were aged older than 75 years. No overall differences in effectiveness were observed between these patients and younger patients. In these studies, patients older than 65 years were more likely than patients less than or equal to 65 years of age to experience pneumonia. Kaposi Sarcoma Of the 28 patients who received POMALYST, 11% were 65 years or older, and 3.6% were 75 years of age or older. The clinical study did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger patients. 8.6 Renal Impairment In patients with severe renal impairment requiring dialysis, the AUC of pomalidomide increased by 38% and the rate of SAE increased by 64% relative to patients with normal renal function; therefore, starting dose adjustment is recommended. For patients with severe renal impairment requiring dialysis, administer POMALYST after the completion of hemodialysis on dialysis days because exposure of pomalidomide could be significantly decreased during dialysis [see Dosage and Administration (2.7) and Clinical Pharmacology (12.3) ] . 8.7 Hepatic Impairment Pomalidomide is metabolized primarily by the liver. Following single dose administration, the AUC of pomalidomide increased 51%, 58%, and 72% in subjects with mild (Child-Pugh class A), moderate (Child-Pugh class B), and severe (Child-Pugh class C) hepatic impairment, respectively compared to subjects with normal liver function. Dose adjustment is recommended in patients with hepatic impairment [see Dosage and Administration (2.8) and Clinical Pharmacology (12.3) ] . 8.8 Smoking Tobacco Cigarette smoking reduces pomalidomide AUC due to CYP1A2 induction. Advise patients that smoking may reduce the efficacy of pomalidomide [see Clinical Pharmacology (12.3) ] .
