Most patients taking THALOMID can be expected to experience adverse reactions. Adverse Reactions in Multiple Myeloma Controlled Clinical Trials The safety analyses were conducted in two controlled clinical studies (Study 1 and Study 2). The safety analysis in Study 1 was conducted on 204 patients who received treatment. Table 1 lists the most common adverse reactions (≥ 10%). The most frequently reported adverse reactions were fatigue, hypocalcemia, edema, constipation, sensory neuropathy, dyspnea, muscle weakness, leukopenia, neutropenia, rash/desquamation, confusion, anorexia, nausea, anxiety/agitation, tremor, fever, weight loss, thrombosis/embolism, neuropathy-motor, weight gain, dizziness, and dry skin. Twenty-three percent of patients (47/204) discontinued due to adverse reactions; 30% (31/102) from the THALOMID/dexamethasone arm and 16% (16/102) from the dexamethasone alone arm.

4 CONTRAINDICATIONS • Pregnancy ( Boxed Warning , 4.1 , 5.1 , 5.2 , 8.1 , 17 ) • Demonstrated hypersensitivity to the drug or its components ( 4.2 , 5.16 , 6.2 ) 4.1 Pregnancy THALOMID is contraindicated in females who are pregnant. THALOMID can cause fetal harm when administered to a pregnant female [see Boxed Warning , Warnings and Precautions (5.1) and Use in Specific Populations (8.1) ] . THALOMID is a powerful human teratogen, inducing a high frequency of severe and life-threatening birth defects, even after a single dose [see Boxed Warning ] . Mortality at or shortly after birth has been reported in about 40% of infants. 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 occurs during THALOMID treatment, the drug should be discontinued immediately. 4.2 Hypersensitivity THALOMID is contraindicated in patients who have demonstrated hypersensitivity to the drug or its components [see Warnings and Precautions (5.16) ].

11 DESCRIPTION THALOMID, α-(N-phthalimido) glutarimide, is an immunomodulatory agent. The empirical formula for thalidomide is C 13 H 10 N 2 O 4 and the gram molecular weight is 258.2. The CAS number of thalidomide is 50-35-1. Chemical Structure of Thalidomide Note: ∙ = asymmetric carbon atom Thalidomide is an off-white to white, odorless, crystalline powder that is soluble at 25°C in dimethyl sulfoxide and sparingly soluble in water and ethanol. The glutarimide moiety contains a single asymmetric center and, therefore, may exist in either of two optically active forms designated S-(-) or R-(+). THALOMID is an equal mixture of the S-(-) and R-(+) forms and, therefore, has a net optical rotation of zero. THALOMID is available in 50 mg, 100 mg, 150 mg and 200 mg capsules for oral administration. Active ingredient: thalidomide. Inactive ingredients: pregelatinized starch and magnesium stearate. The 50 mg capsule shell contains gelatin, titanium dioxide, and black ink. The 100 mg capsule shell contains black iron oxide, yellow iron oxide, titanium dioxide, gelatin, and black ink. The 150 mg capsule shell contains FD&C blue #2, black iron oxide, yellow iron oxide, titanium dioxide, gelatin, and black and white ink. The 200 mg capsule shell contains FD&C blue #2, titanium dioxide, gelatin, and white ink. Chemical Structure

2 DOSAGE AND ADMINISTRATION • MM: 200 mg orally once daily. The recommended dose of dexamethasone is 40 mg/day on days 1-4, 9-12, and 17-20 every 28 days. ( 2.2 ) • ENL: 100 to 300 mg/day for an episode of cutaneous ENL. Up to 400 mg/day for severe cutaneous ENL. ( 2.3 ) 2.1 Required Baseline Testing Drug prescribing to females of reproductive potential is contingent upon initial and continued negative results of pregnancy testing [see Warnings and Precautions (5.1 and 5.2) ] . THALOMID must only be administered in compliance with all of the terms outlined in the THALOMID REMS program. THALOMID may only be prescribed by prescribers certified with the THALOMID REMS program and may only be dispensed by pharmacists certified with the THALOMID REMS program. 2.2 Recommended Dosage for Multiple Myeloma The recommended dose of THALOMID in combination with dexamethasone is 200 mg once daily (in 28-day treatment cycles) orally with water, preferably at bedtime and at least 1 hour after the evening meal. The dose of dexamethasone is 40 mg daily administered orally on days 1-4, 9-12, and 17-20 every 28 days. 2.3 Recommended Dosage for Erythema Nodosum Leprosum The recommended dose of THALOMID for an episode of cutaneous ENL is 100 to 300 mg/day once daily orally with water, preferably at bedtime and at least 1 hour after the evening meal. Initiate dosing for patients weighing less than 50 kilograms at the low end of the dose range. Consider dosing in the higher dosage range for patients with a severe cutaneous ENL reaction, or in those who have previously required higher doses to control the reaction (possibly up to 400 mg/day) once daily at bedtime or in divided doses with water, at least 1 hour after meals. Consider concomitant use of corticosteroids in patients with moderate to severe neuritis associated with a severe ENL reaction. Steroid usage can be tapered and discontinued when the neuritis has ameliorated. Continue dosing with THALOMID until signs and symptoms of active reaction have subsided, usually a period of at least 2 weeks. Patients may then be tapered off medication in 50 mg decrements every 2 to 4 weeks. Patients who have a documented history of requiring prolonged maintenance treatment to prevent the recurrence of cutaneous ENL or who flare during tapering should be maintained on the minimum dose necessary to control the reaction. Tapering off medication should be attempted every 3 to 6 months, in decrements of 50 mg every 2 to 4 weeks. 2.4 Dosage Modifications for Adverse Reactions Interrupt THALOMID for constipation, somnolence, or peripheral neuropathy. Consider a reduced dose upon resumption of treatment. Consider dose reduction, delay, or discontinuation in patients who develop National Cancer Institute Common Toxicity Criteria (NCI CTC) Grade 3 or 4 adverse reactions and/or based on clinical judgment. Permanently discontinue THALOMID for angioedema, anaphylaxis, Grade 4 rash, skin exfoliation, bullae, or any other severe dermatologic reactions [see Warnings and Precautions (5.12 and 5.16) ] .

1 INDICATIONS AND USAGE • THALOMID in combination with dexamethasone is indicated for the treatment of patients with newly diagnosed multiple myeloma (MM). ( 1.1 ) • THALOMID is indicated for the acute treatment of the cutaneous manifestations of moderate to severe erythema nodosum leprosum (ENL). THALOMID is not indicated as monotherapy for such ENL treatment in the presence of moderate to severe neuritis. THALOMID is also indicated as maintenance therapy for prevention and suppression of the cutaneous manifestations of ENL recurrence. ( 1.2 ) 1.1 Multiple Myeloma THALOMID in combination with dexamethasone is indicated for the treatment of patients with newly diagnosed multiple myeloma (MM) [see Clinical Studies (14.1) ] . 1.2 Erythema Nodosum Leprosum THALOMID is indicated for the acute treatment of the cutaneous manifestations of moderate to severe erythema nodosum leprosum (ENL). THALOMID is not indicated as monotherapy for such ENL treatment in the presence of moderate to severe neuritis. THALOMID is also indicated as maintenance therapy for prevention and suppression of the cutaneous manifestations of ENL recurrence [see Clinical Studies (14.2) ].

9 DRUG ABUSE AND DEPENDENCE Physical and psychological dependence has not been reported in patients taking THALOMID; however, as with other tranquilizers/hypnotics, thalidomide has been reported to result in habituation to its soporific effects.

10 OVERDOSAGE There is no specific antidote for a THALOMID overdose. In the event of an overdose, the patient's vital signs should be monitored and appropriate supportive care given to maintain blood pressure and respiratory status.

7 DRUG INTERACTIONS • Use caution if other drugs which have sedative and hypnotic properties, slow cardiac conduction and/or cause peripheral neuropathy must be used. ( 7.1 , 7.2 , 7.3 ) • It is not known whether concomitant use of hormonal contraceptives further increases the risk of thromboembolism with THALOMID. ( 5.15 , 7.4 ) • Patients taking concomitant therapies such as erythropoietin stimulating agents or estrogen containing therapies may have an increased risk of thromboembolism. ( 7.7 ) 7.1 Opioids, Antihistamines, Antipsychotics, Anti-anxiety Agents, or Other CNS Depressants (Including Alcohol) The use of opioids, antihistamines, antipsychotics, anti-anxiety agents, or other CNS depressants concomitantly with THALOMID may cause an additive sedative effect and should be avoided. 7.2 Drugs which Cause Bradycardia The use of drugs which slow cardiac conduction concomitantly with THALOMID may cause an additive bradycardic effect and should be used with caution. Cardiovascular medications which may cause bradycardia include calcium channel blockers, beta blockers, alpha/beta-adrenergic blockers, and digoxin. Non-cardiac drugs that may cause bradycardia include H2 blockers (e.g., famotidine, cimetidine), lithium, tricyclic antidepressants and neuromuscular blockers (succinylcholine). In 16 healthy men, the pharmacokinetic profile of a single 0.5 mg digoxin dose was similar with and without the coadministration of THALOMID 200 mg/day at steady state levels. The single dose of digoxin had no effect on the pharmacokinetic profile of THALOMID. The safety of long-term concomitant use of THALOMID and digoxin has not been evaluated. 7.3 Drugs which Cause Peripheral Neuropathy The use of drugs which cause peripheral neuropathy (e.g., bortezomib, amiodarone, cisplatin, docetaxel, paclitaxel, vincristine, disulfiram, phenytoin, metronidazole, alcohol) can cause an additive effect and should be used with caution. 7.4 Hormonal Contraceptives Hormonal contraceptives increase the risk of thromboembolism. It is not known whether concomitant use of hormonal contraceptives further increases the risk of thromboembolism with THALOMID. In 10 healthy women, the pharmacokinetic profiles of norethindrone and ethinyl estradiol following administration of a single dose containing 1.0 mg of norethindrone acetate and 75 mcg of ethinyl estradiol were studied. The results were similar with and without coadministration of THALOMID 200 mg/day to steady-state levels. 7.5 Warfarin In 13 healthy men, the pharmacokinetic profile and international normalized ratio (INR) of prothrombin time for warfarin, following a single oral dose of 25 mg, were similar with and without the coadministration of THALOMID 200 mg/day at steady-state levels. The single dose of warfarin had no effect on the pharmacokinetic profile of thalidomide. 7.6 Drugs that Interfere with Hormonal Contraceptives Concomitant use of HIV-protease inhibitors, griseofulvin, modafinil, penicillins, rifampin, rifabutin, phenytoin, carbamazepine, or certain herbal supplements such as St. John's Wort with hormonal contraceptive agents may reduce the effectiveness of the contraception up to one month after discontinuation of these concomitant therapies. Therefore, females requiring treatment with one or more of these drugs must use two OTHER effective or highly effective methods of contraception while taking THALOMID. 7.7 Concomitant Therapies that may Increase the Risk of Thromboembolism Erythropoietic agents, or other agents that may increase the risk of thromboembolism, such as estrogen containing therapies, should be used with caution in multiple myeloma patients receiving THALOMID with dexamethasone [see Warnings and Precautions (5.3) ].

12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action The mechanism of action of THALOMID is not fully understood. Cellular activities of thalidomide are mediated through its target cereblon, a component of a cullin ring E3 ubiquitin ligase enzyme complex. THALOMID possesses immunomodulatory, anti-inflammatory and antiangiogenic properties. Available data from in vitro studies and clinical trials suggest that the immunologic effects of this compound can vary substantially under different conditions, but may be related to suppression of excessive tumor necrosis factor-alpha (TNF-α) production and down-modulation of selected cell surface adhesion molecules involved in leukocyte migration. For example, administration of thalidomide has been reported to decrease circulating levels of TNF-α in patients with erythema nodosum leprosum (ENL); however, it has also been shown to increase plasma TNF-α levels in HIV-seropositive patients. Other anti-inflammatory and immunomodulatory properties of thalidomide may include suppression of macrophage involvement in prostaglandin synthesis, and modulation of interleukin-10 and interleukin-12 production by peripheral blood mononuclear cells. Thalidomide treatment of multiple myeloma patients is accompanied by an increase in the number of circulating natural killer cells, and an increase in plasma levels of interleukin-2 and interferon-gamma (T cell-derived cytokines associated with cytotoxic activity). Thalidomide was found to inhibit angiogenesis in a human umbilical artery explant model in vitro . The cellular processes of angiogenesis inhibited by thalidomide may include the proliferation of endothelial cells. 12.3 Pharmacokinetics Absorption Absorption of THALOMID is slow after oral administration. The maximum plasma concentrations are reached approximately 2-5 hours after administration. The absolute bioavailability of thalidomide from thalidomide capsules has not yet been characterized in human subjects due to its poor aqueous solubility. Based on the 14 C-radiolabel thalidomide study in human, greater than 90% of the total radioactivity is recovered in urine suggesting good oral absorption. While the extent of absorption (as measured by area under the curve [AUC]) is proportional to dose in healthy subjects, the observed peak concentration (C max ) increased in a less than proportional manner (see Table 5 below). This lack of C max dose proportionality, coupled with the observed increase in T max values, suggests that the poor solubility of thalidomide in aqueous media may be hindering the rate of absorption. Table 5: Pharmacokinetic Parameter Values for THALOMID Mean (%CV) Population/ Single Dose AUC 0-∞ mcg∙hr/mL C max mcg/mL T max (hrs) Half-life (hrs) Healthy Subjects (n=14) 50 mg 4.9 (16%) 0.62 (52%) 2.9 (66%) 5.52 (37%) 200 mg 18.9 (17%) 1.76 (30%) 3.5 (57%) 5.53 (25%) 400 mg 36.4 (26%) 2.82 (28%) 4.3 (37%) 7.29 (36%) Patients with Hansen's Disease (n=6) 400 mg 46.4 (44.1%) 3.44 (52.6%) 5.7 (27%) 6.86 (17%) Coadministration of THALOMID (thalidomide) with a high-fat meal causes minor (<10%) changes in the observed AUC and C max values; however, it causes an increase in T max to approximately 6 hours. Distribution In human plasma, the geometric mean plasma protein binding was 55% and 66%, respectively, for (+)-(R)- and (-)-(S)-thalidomide. In a pharmacokinetic study of thalidomide in HIV-seropositive adult male subjects receiving thalidomide 100 mg/day, thalidomide was detectable in the semen. Metabolism In a 14 C-radiolabel ADME study in humans, unchanged drug is the predominant circulating component. Thalidomide is not a substrate of the cytochrome P450 system. At therapeutic concentrations, thalidomide is not an inhibitor or inducer of human cytochrome P450 enzymes in vitro . Pharmacokinetic drug-drug interactions with substrates, inhibitors or inducers of CYP450 are not anticipated. Elimination The mean elimination half-life of thalidomide in plasma following single oral doses between 50 mg and 400 mg was 5.5 to 7.3 hours. Following a single 400 mg oral dose of radiolabeled thalidomide, the total mean recovery was 93.6% of the administered dose by Day 8. The majority of the radioactive dose was excreted within 48 hours following dose administration. In humans, 14 C-thalidomide is primarily excreted in urine (91.9% of the radioactive dose) mainly as hydrolytic metabolites while fecal excretion is minor (<2% of the dose). Unchanged thalidomide is not eliminated by the kidney to a notable degree (<3.5% of the dose). Effects of Weight There is a linear relationship between body weight and estimated thalidomide clearance. In MM patients with body weight from 47-133 kg, thalidomide clearance ranged from approximately 6-12 L/h, representing an increase in thalidomide clearance of 0.605 L/h per 10 kg body weight increase. Effects of Age, Gender and Race Analysis of the data from pharmacokinetic studies in healthy volunteers and patients with Hansen's disease ranging in age from 20 to 69 years does not reveal any age-related changes. While a comparative trial of the effects of gender on thalidomide pharmacokinetics has not been conducted, examination of the data for thalidomide does not reveal any significant gender differences in pharmacokinetic parameter values. Pharmacokinetic differences due to race have not been studied. Pharmacokinetic Data in Special Populations HIV-seropositive Subjects: There is no apparent significant difference in measured pharmacokinetic parameter values between healthy human subjects and HIV-seropositive subjects following single-dose administration of THALOMID Capsules. Patients with Hansen's Disease: Analysis of data from a small study in Hansen's patients suggests that these patients, relative to healthy subjects, may have an increased bioavailability of THALOMID. The increase is reflected both in an increased area under the curve and in increased peak plasma levels. The clinical significance of this increase is unknown. Pediatric: No pharmacokinetic data are available in subjects below the age of 18 years. Patients with Renal Impairment: Renal impairment is not expected to influence drug exposure since <3.5% of the dose is excreted in the urine as unchanged drug. Patients with Hepatic Impairment: No clinical studies have been conducted in patients with hepatic impairment.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility Two-year carcinogenicity studies were conducted in male and female rats and mice. No compound-related tumorigenic effects were observed at the highest dose levels of 3,000 mg/kg/day to male and female mice (38-fold greater than the highest recommended daily human dose of 400 mg based upon body surface area [BSA]), 3,000 mg/kg/day to female rats (75-fold the maximum human dose based upon BSA), and 300 mg/kg/day to male rats (7.5-fold the maximum human dose based upon BSA). Thalidomide was neither mutagenic nor genotoxic in the following assays: the Ames bacterial ( S. typhimurium and E. coli ) reverse mutation assay, a Chinese hamster ovary cell (AS52/XPRT) forward mutation assay, and an in vivo mouse micronucleus test. Fertility studies were conducted in male and female rabbits; no compound-related effects in mating and fertility indices were observed at any oral thalidomide dose level including the highest of 100 mg/kg/day to female rabbits and 500 mg/kg/day to male rabbits (approximately 5- and 25- fold the maximum human dose, respectively, based upon BSA). Testicular pathological and histopathological effects (classified as slight) were seen in male rabbits at dose levels ≥30 mg/kg/day (approximately 1.5-fold the maximum human dose based upon BSA).

This Medication Guide has been approved by the U.S. Food and Drug Administration. Revised: December 2022 MEDICATION GUIDE THALOMID ® (tha-lo-mid) (thalidomide) capsules What is the most important information I should know about THALOMID? Before you begin taking THALOMID, you must read and agree to all of the instructions in the THALOMID REMS® program. For more information, call 1-888-423-5436 or go to www.thalomidrems.com. Before prescribing THALOMID, your healthcare provider will explain the THALOMID REMS program to you and have you sign the Patient-Physician Agreement Form. THALOMID can cause serious side effects including: • Severe and life-threatening human birth defects (deformed babies) or death of an unborn baby. Females who are pregnant or who plan to become pregnant must not take THALOMID. • Females must not get pregnant: o For at least 4 weeks before starting THALOMID o While taking THALOMID o During any breaks (interruptions) in your treatment with THALOMID o For at least 4 weeks after stopping THALOMID • 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. o 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 THALOMID. 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 THALOMID. o Stop taking THALOMID and call your healthcare provider right away if you have unprotected sex or if you think your birth control has failed. • If you become pregnant while taking THALOMID, stop taking it right away and call your healthcare provider. If your healthcare provider is not available, you should 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 THALOMID during pregnancy, or if their male partner takes THALOMID and they are exposed during pregnancy. You can enroll in this registry by calling the REMS Call Center at the phone number listed above. • THALOMID 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 THALOMID, during any breaks (interruptions) in your treatment with THALOMID, and for up to 4 weeks after stopping THALOMID. 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 THALOMID, during any breaks (interruptions) in your treatment, and for 4 weeks after stopping THALOMID. If a female becomes pregnant with your sperm, the baby may be exposed to THALOMID and may be born with birth defects. • Men, if your female partner becomes pregnant, you should call your healthcare provider right away. • Blood clots. People with multiple myeloma (MM) who take THALOMID may have an increased risk for blood clots in their arteries, veins, and lungs. This risk is even higher if you take the medicine dexamethasone with THALOMID to treat your MM. Heart attacks and strokes may also happen if you take THALOMID with dexamethasone. Before taking THALOMID, tell your healthcare provider 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 THALOMID: o 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 o 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 o 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 THALOMID? THALOMID is a prescription medicine used: • to treat people who have been newly diagnosed with multiple myeloma (MM) in combination with the medicine dexamethasone. • to treat people who have moderate to severe new lesions of leprosy. THALOMID is not used by itself to treat the skin lesions when there is moderate to severe nerve pain. • as maintenance treatment to prevent and keep the skin lesions of leprosy from coming back (recurring). It is not known if THALOMID is safe and effective in children under 12 years of age. Who should not take THALOMID? Do not take THALOMID if you: • are pregnant, plan to become pregnant, or become pregnant during treatment with THALOMID. See "What is the most important information I should know about THALOMID?" • are allergic to thalidomide or any of the ingredients in THALOMID. See the end of this Medication Guide for a complete list of ingredients in THALOMID. What should I tell my healthcare provider before taking THALOMID? Before you take THALOMID, tell your healthcare provider about all of your medical conditions, including if you: • have a history of seizures • drink alcohol • plan to have surgery • are breastfeeding. THALOMID must not be used by females who are breastfeeding. It is not known if THALOMID 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. THALOMID and other medicines may affect each other, causing serious side effects. Talk with your healthcare provider before taking any new medicines. Certain medicines can affect the way that birth control pills, injections, transdermal systems (patches), or implants work. You could become pregnant. See "What is the most important information I should know about THALOMID?" Know the medicines you take. Keep a list of them to show your healthcare provider and pharmacist. How should I take THALOMID? • Take THALOMID exactly as prescribed and follow all the instructions of the THALOMID REMS program. • Keep THALOMID in the blister pack until you take your daily dose. • Swallow THALOMID capsules whole with water. • THALOMID is taken 1 time each day, at least 1 hour after your evening meal. Bedtime is the preferred time to take THALOMID. • Do not open or crush THALOMID capsules or handle them any more than needed. o If powder from the THALOMID capsule comes in contact with your skin, wash the skin right away with soap and water. o If powder from the THALOMID capsule comes in contact with the inside of your eyes, nose, and mouth, flush well with water. • If you miss a dose of THALOMID and it has been less than 12 hours since your regular time, take it as soon as you remember. If it has been more than 12 hours, just skip your missed dose. Do not take 2 doses at the same time. • If you take too much THALOMID, call your healthcare provider right away. What should I avoid while taking THALOMID? • See "What is the most important information I should know about THALOMID?" • Females: Do not get pregnant and do not breastfeed while taking THALOMID. • Males: Do not donate sperm. • Do not share THALOMID with other people. It may cause birth defects and other serious problems. • Do not donate blood while you take THALOMID, during any breaks (interruptions) in your treatment, and for 4 weeks after stopping THALOMID. If someone who is pregnant gets your donated blood, her baby may be exposed to THALOMID and may be born with birth defects. • THALOMID can cause drowsiness and sleepiness. Avoid drinking alcohol, operating machinery, and driving a car when taking THALOMID. Avoid taking other medicines that may cause drowsiness without talking to your healthcare provider first. What are the possible side effects of THALOMID? THALOMID can cause serious side effects, including: • See "What is the most important information I should know about THALOMID?" • Drowsiness and sleepiness. See "What should I avoid while taking THALOMID?" • Nerve damage. Nerve damage is common with THALOMID. If the nerve damage is severe, it may not go away. Stop taking THALOMID and call your healthcare provider right away if you have any of these early symptoms of nerve damage in your hands, legs, or feet: o numbness o tingling o pain o burning sensation • Dizziness and decreased blood pressure when changing positions. THALOMID may cause a decrease in your blood pressure, and you may feel dizzy when you go from a lying down or sitting position to standing up. When changing positions, sit upright for a few minutes before standing to help prevent this. • Decreased white blood cell count. THALOMID can cause decreased white blood cell counts, including neutrophils. Neutrophils are a type of white blood cell that is important in fighting bacterial infections. Your healthcare provider should check your white blood count before and regularly while you take THALOMID. If your neutrophils are too low you should not start THALOMID and if they are low during treatment, your dose of THALOMID may need to be changed. • Decreased platelet count. THALOMID can cause decreased platelet counts. Your healthcare provider should check your platelet count before and regularly while you take THALOMID. If your platelets are too low, your healthcare provider may lower your dose, delay your dose, or completely stop treatment. Tell your healthcare provider if you have signs and symptoms of bleeding such as: o small red or purple spots on your body o unusual bleeding or bruising o nosebleeds o bright red or tar like stools o vomiting or coughing up blood • Increased HIV virus in the blood. If you are HIV positive, your healthcare provider should check your viral load after one month and three months of treatment, then every 3 months after that. • Slow heartbeat (bradycardia). Tell your healthcare provider if you have a slow heartbeat, fainting, dizziness or shortness of breath. • Severe skin reactions and severe allergic reactions. Severe skin reactions and severe allergic reactions can happen with THALOMID and may cause death. Call your healthcare provider right away if you develop any of the following signs or symptoms during treatment with THALOMID: o a red, itchy, skin rash o peeling of your skin or blisters o severe itching o fever Get emergency medical help right away if you develop any of the following signs or symptoms during treatment with THALOMID: o swelling of your lips, mouth, tongue, or throat o trouble breathing or swallowing o raised red areas on your skin (hives) o a very fast heartbeat o you feel dizzy or faint • Seizures. Tell your healthcare provider right away if you have a seizure while taking THALOMID. • Tumor Lysis Syndrome (TLS). TLS is caused by the fast breakdown of cancer cells. TLS can cause kidney failure and the need for dialysis treatment, abnormal heart rhythm, seizure and sometimes death. Your healthcare provider may do blood tests to check you for TLS. • Birth control risks. Certain birth control methods may pose a higher risk of serious side effects and should not be used in some females. These risks include severe decreased white blood cell counts, low platelet counts, and blood clots. Use of an intrauterine device (IUD) or implantable birth control may also increase your risk of infection or bleeding during insertion, removal or during use of the device. Your healthcare provider may tell you to decrease your dose, temporarily stop or permanently stop taking THALOMID if you develop certain serious side effects during treatment with THALOMID. The most common side effects of THALOMID for treatment of multiple myeloma include: • tiredness • decreased calcium levels • swelling of the hands and feet • constipation • numbness or tingling • shortness of breath • muscle weakness • low blood counts • skin rash or peeling. See "Severe skin reactions and severe allergic reactions" above. • confusion • decreased appetite • nausea • anxiety • decreased energy or strength • tremor • fever • weight loss • blood clots • muscle twitching and cramping • weight gain • dizziness • dry skin The most common side effects of THALOMID for treatment of leprosy include: • sleepiness • rash • headache These are not all the possible side effects of THALOMID. Call your doctor for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088. How should I store THALOMID? • Store THALOMID at room temperature between 68°F to 77°F (20°C to 25°C). • Protect from light. • Return any unused THALOMID to THALOMID REMS by calling 1-888-423-5346 or your healthcare provider.

14 CLINICAL STUDIES 14.1 Multiple Myeloma (MM) The efficacy and safety of THALOMID in patients with multiple myeloma were evaluated in two randomized, multi-center studies (Study 1 and Study 2). Study 1 was an open-label study which randomized 207 symptomatic patients with newly diagnosed MM to THALOMID plus dexamethasone (N = 103) versus dexamethasone alone (N=104). The THALOMID dose was 200 mg daily and the dexamethasone dose was 40 mg orally once daily on days 1-4, 9-12, and 17-20 every 28-days. Each group was treated for four 28-day cycles. Study 2 randomized 470 newly diagnosed patients with MM to THALOMID plus dexamethasone (N=235) versus placebo plus dexamethasone (N=235). In the THALOMID/dexamethasone arm, a starting dose of thalidomide 50 mg was escalated to 200 mg/day (cycle 2) once daily for 28 days. Patients in both treatment groups took 40 mg of dexamethasone once daily given on days 1-4, 9-12, and 17-20 (every 28 days). Beginning with Cycle 5, the dose of dexamethasone was reduced to 40 mg once daily on Days 1 to 4 of each cycle. Treatment continued as tolerated until disease progression. Baseline demographics for both studies are presented in Table 6 and disease characteristics for the study population are summarized in Tables 7 (Study 1) and 8 (Study 2).

Response rates based on serum or urine paraprotein measurements were significantly higher in the combination arm (52% vs. 36%). The primary efficacy endpoint in Study 2 was time to progression (TTP), defined as the time from randomization to the first documentation of disease progression, based on the myeloma response criteria. A preplanned interim analysis for Study 2 demonstrated that the combination of THALOMID plus dexamethasone was superior to placebo plus dexamethasone with respect to TTP (Table 9).

A subset of patients with ENL controlled on thalidomide demonstrated repeated relapse upon drug withdrawal and remission with reinstitution of therapy. Twenty U.S. patients between the ages of 11 and 17 years were treated with thalidomide, generally at 100 mg daily. Response rates and safety profiles were similar to that observed in the adult population. Thirty-two other published studies containing over 1600 patients consistently report generally successful treatment of the cutaneous manifestations of moderate to severe ENL with thalidomide.

8.5 Geriatric Use One hundred and seventy-six (52%) of 336 patients treated with THALOMID in combination with dexamethasone were ≥65 of age while 50 (15%) were ≥75. Patients ≥65 years of age on Study 2 had higher incidences of atrial fibrillation, constipation, fatigue, nausea, hypokalemia, deep venous thrombosis, hyperglycemia, pulmonary embolism, and asthenia compared to patients <65.

8.4 Pediatric Use Safety and effectiveness in pediatric patients below the age of 12 years have not been established.

8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in females exposed to THALOMID during pregnancy as well as female partners of male patients who are exposed to THALOMID. This registry is also used to understand the root cause for the pregnancy. Report any suspected fetal exposure to THALOMID to the FDA via the MedWatch program at 1-800-FDA-1088 and to the REMS Call Center at 1-888-423-5436. Risk Summary Based on the mechanism of action [see Clinical Pharmacology (12.1) ] , human and animal data (see Data ) , THALOMID can cause embryo-fetal harm when administered to a pregnant female and is contraindicated during pregnancy [see Boxed Warning , Contraindications (4.1) , and Warnings and Precautions (5.1) ] . THALOMID 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. Even a single dose taken by a pregnant woman can cause birth defects. 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 the patient to an obstetrician/gynecologist experienced in reproductive toxicity for further evaluation and counseling. Report any suspected fetal exposure to THALOMID to the FDA via the MedWatch program at 1-800-FDA-1088 and also the REMS Call Center at 1-888-423-5436. Thalidomide crossed the placenta after administration to pregnant hamsters (see Data ) . The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. 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 A pre- and postnatal reproductive toxicity study was conducted in pregnant female rabbits. Compound-related increased abortion incidences and elevated fetotoxicity were observed at the lowest oral dose level of 30 mg/kg/day (approximately 1.5-fold the maximum human dose based upon BSA) and all higher dose levels. Neonatal mortality was elevated at oral dose levels to the lactating female rabbits ≥150 mg/kg/day (approximately 7.5-fold the maximum human dose based upon BSA). No delay in postnatal development, including learning and memory functions, were noted at the oral dose level to the lactating female rabbits of 150 mg/kg/day (average thalidomide concentrations in milk ranged from 22 to 36 mcg per mL). In a study conducted in pregnant rabbits, thalidomide levels in fetal plasma were approximately 11% to 73% of the maternal C max . In a study conducted with 14 C-thalidomide (150 mg/kg orally) in pregnant hamsters, radioactivity was detected in the embryo, and the relative concentrations of radioactivity in the embryo and maternal plasma were about the same at 4, 12 and 24 hours after dosing. Based on the radioactivity data, thalidomide crossed the placental barrier, and the fetal levels of drug-related material were approximately similar to those of maternal levels.

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 THALOMID during pregnancy as well as female partners of male patients who are exposed to THALOMID.

Based on the radioactivity data, thalidomide crossed the placental barrier, and the fetal levels of drug-related material were approximately similar to those of maternal levels. 8.2 Lactation Risk Summary There is no information regarding the presence of thalidomide in human milk, the effects of THALOMID on the breastfed child, or the effects of THALOMID on milk production. Thalidomide is excreted in the milk of lactating rabbits (see Data ) . Because many drugs are excreted in human milk and because of the potential for adverse reactions in a breastfed child from THALOMID, advise women not to breastfeed during treatment with THALOMID. Data Animal Data In lactating female rabbits at an oral dose of 150 mg/kg/day, the average thalidomide concentrations in milk ranged from 22 to 36 mcg per mL. In the study of lactating female rabbits, high concentrations of thalidomide (7741 – 71425 ng per mL) were noted in milk during four weeks of pre-weaning period. Milk concentrations were 1.16 - 2.11, 1.05 – 2.43, and 0.64 – 3.63 times that of plasma at 30, 150 and 500 mg/kg thalidomide doses, respectively; thalidomide, as a lipophilic compound, distributed into milk, with concentrations attained similar to or slightly higher than those of systemic concentrations. 8.3 Females and Males of Reproductive Potential Pregnancy Testing THALOMID 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 THALOMID therapy and during therapy. Advise females of reproductive potential that they must avoid pregnancy 4 weeks before therapy, while taking THALOMID, during dose interruptions and for at least 4 weeks after completing therapy. Females of reproductive potential must have 2 negative pregnancy tests before initiating THALOMID. The first test should be performed within 10-14 days, and the second test within 24 hours prior to prescribing THALOMID. 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. THALOMID 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 THALOMID, during therapy, during dose interruptions, and continuing for 4 weeks following discontinuation of THALOMID 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 Thalidomide is present in the semen of males who take THALOMID. Therefore, males must always use a latex or synthetic condom during any sexual contact with females of reproductive potential while taking THALOMID, during dose interruptions and for up to 28 days after discontinuing THALOMID, even if they have undergone a successful vasectomy. Male patients taking THALOMID must not donate sperm. Infertility Based on findings in animals, male fertility may be compromised by treatment with THALOMID [see Nonclinical Toxicology (13.1) ] . 8.4 Pediatric Use Safety and effectiveness in pediatric patients below the age of 12 years have not been established. 8.5 Geriatric Use One hundred and seventy-six (52%) of 336 patients treated with THALOMID in combination with dexamethasone were ≥65 of age while 50 (15%) were ≥75. Patients ≥65 years of age on Study 2 had higher incidences of atrial fibrillation, constipation, fatigue, nausea, hypokalemia, deep venous thrombosis, hyperglycemia, pulmonary embolism, and asthenia compared to patients <65.

WARNING: EMBRYO-FETAL TOXICITY AND VENOUS THROMBOEMBOLISM WARNING: EMBRYO-FETAL TOXICITY AND VENOUS THROMBOEMBOLISM See full prescribing information for complete boxed warning. EMBRYO -FETAL TOXICITY • If THALOMID is taken during pregnancy, it can cause severe birth defects or embryo-fetal death. THALOMID should never be used by females who are pregnant or who could be pregnant while taking the drug. Even a single dose [1 capsule (regardless of strength)] taken by a pregnant woman during her pregnancy can cause severe birth defects. • Pregnancy must be excluded before start of treatment. Prevent pregnancy thereafter by the use of two reliable methods of contraception. ( 5.1 , 8.3 ) THALOMID is only available through a restricted distribution program, the THALOMID REMS ® program ( 5.2 ). VENOUS THROMBOEMBOLISM • Significant increased risk of deep vein thrombosis (DVT) and pulmonary embolism (PE) in patients with multiple myeloma receiving THALOMID with dexamethasone ( 5.3 ). EMBRYO-FETAL TOXICITY If THALOMID is taken during pregnancy, it can cause severe birth defects or embryo-fetal death. THALOMID should never be used by females who are pregnant or who could become pregnant while taking the drug. Even a single dose [1 capsule (regardless of strength)] taken by a pregnant woman during her pregnancy can cause severe birth defects. Because of this toxicity and in an effort to make the chance of embryo-fetal exposure to THALOMID as negligible as possible, THALOMID is approved for marketing only through a special restricted distribution program: THALOMID REMS program, approved by the Food and Drug Administration. Information about THALOMID and the THALOMID REMS program is available at www.thalomidrems.com or by calling the REMS Call Center at 1-888-423-5436. VENOUS THROMBOEMBOLISM The use of THALOMID in multiple myeloma results in an increased risk of venous thromboembolism, such as deep venous thrombosis and pulmonary embolism. This risk increases significantly when THALOMID is used in combination with standard chemotherapeutic agents including dexamethasone. In one controlled trial, the rate of venous thromboembolism was 22.5% in patients receiving THALOMID in combination with dexamethasone compared to 4.9% in patients receiving dexamethasone alone (p = 0.002). Patients and physicians are advised to be observant for the signs and symptoms of thromboembolism. Instruct patients to seek medical care if they develop symptoms such as shortness of breath, chest pain, or arm or leg swelling. Consider thromboprophylaxis based on an assessment of individual patients' underlying risk factors.
