Thalomid

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) ].

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) ] .

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.

Table 2 lists the most common adverse reactions (≥10%) that were observed. Table 3 lists the most common Grade 3/4 adverse reactions (occurring at >2%) that were observed. The adverse reactions most often reported by patients treated with THALOMID/dexamethasone were constipation, peripheral edema, tremor, asthenia, dizziness and fatigue. Adverse reactions with a frequency at least 2-fold higher in the THALOMID/dexamethasone group than in the placebo/dexamethasone group include constipation, tremor, deep vein thrombosis and peripheral sensory neuropathy. Twenty-six percent of patients (121/466) discontinued due to adverse reactions; 37% (86/234) from the THALOMID/dexamethasone arm and 15% (35/232) from the placebo/dexamethasone arm.

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) ].
