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) ] .

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) ].

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. 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. 8.2 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. …

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.

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

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.
