/BOXED WARNING/ WARNING: EMBRYO-FETAL TOXICITY. If thalidomide is taken during pregnancy, it can cause severe birth defects or embryo-fetal death. Thalidomide 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 (thalidomide) as negligible as possible, Thalomid (thalidomide) is approved for marketing only through a special restricted distribution program: Thalomid REMS program, approved by the Food and Drug Administration. This program was formerly known as the "System for Thalidomide Education and Prescribing Safety (S.T.E.P.S. program)".

/BOXED WARNING/ WARNING: VENOUS THROMBOEMBOLISM. The use of Thalomid (thalidomide) in multiple myeloma results in an increased risk of venous thromboembolism, such as deep venous thrombosis and pulmonary embolism. This risk increases significantly when thalidomide 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 thalidomide 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.

Use of thalidomide in patients with multiple myeloma is associated with increased risk of venous thromboembolic events (e.g., deep venous thrombosis, pulmonary embolus). Such risk increases substantially when thalidomide is used in combination with standard chemotherapy, including dexamethasone. In a controlled clinical trial, an increased incidence of venous thromboembolic events was observed in patients receiving thalidomide in combination with dexamethasone compared with those receiving dexamethasone alone (22.5 versus 4.9%). Patients and clinicians are advised to watch for signs and symptoms of thromboembolism. Patients should be instructed to notify a clinician if they develop shortness of breath, chest pain, and/or arm or leg swelling.

Thalidomide is known to cause nerve damage that may be permanent. Peripheral neuropathy is a common (> or =10%) and potentially severe adverse reaction of treatment with thalidomide that may be irreversible. Peripheral neuropathy generally occurs following chronic use over a period of months; however, peripheral neuropathy following relatively short-term use has been reported. The correlation with cumulative dose is unclear. Symptoms may occur some time after thalidomide treatment has been stopped and may resolve slowly or not at all.

Thalidomide is an immunomodulatory agent with a spectrum of activity that is not fully characterized. Thalidomide is racemic — it contains both left and right handed isomers in equal amounts: one enantiomer is effective against morning sickness, and the other is teratogenic. The enantiomers are converted to each other in vivo. That is, if a human is given D-thalidomide or L-thalidomide, both isomers can be found in the serum. Hence, administering only one enantiomer will not prevent the teratogenic effect in humans.
Teratogens
An agent that causes the production of physical defects in the developing embryo. (See all compounds classified as Teratogens.)
Immunosuppressive Agents
Agents that suppress immune function by one of several mechanisms of action. Classical cytotoxic immunosuppressants act by inhibiting DNA synthesis. Others may act through activation of T-CELLS or by inhibiting the activation of HELPER CELLS. While immunosuppression has been brought about in the past primarily to prevent rejection of transplanted organs, new applications involving mediation of the effects of INTERLEUKINS and other CYTOKINES are emerging. (See all compounds classified as Immunosuppressive Agents.)
Leprostatic Agents
Substances that suppress Mycobacterium leprae, ameliorate the clinical manifestations of leprosy, and/or reduce the incidence and severity of leprous reactions. (See all compounds classified as Leprostatic Agents.)
Angiogenesis Inhibitors
Agents and endogenous substances that antagonize or inhibit the development of new blood vessels. (See all compounds classified as Angiogenesis Inhibitors.)

Absorption
The absolute bioavailability has not yet been characterized in human subjects due to its poor aqueous solubility. In studies of both healthy volunteers and subjects with Hansen’s disease, the mean time to peak plasma concentrations (Tmax) ranged from 2.9 to 5.7 hours indicating that thalidomide is slowly absorbed from the gastrointestinal tract.
Route of Elimination
Thalidomide itself has less than 0.7% of the dose excreted in the urine as unchanged drug.
... Thalidomide given orally to rats was poorly absorbed.

Thalidomide itself does not appear to be hepatically metabolized to any large extent, but appears to undergo non-enzymatic hydrolysis in plasma to multiple metabolites. Thalidomide may be metabolized hepatically by enzymes of the cytochrome P450 enzyme system. The end product of metabolism, phthalic acid, is excreted as a glycine conjugate.
Studies on thalidomide metabolism in humans have not been done. In animals, nonenzymatic hydrolytic cleavage appears to be the main pathway of degradation, producing seven major and at least five minor hydrolysis products. Thalidomide may be metabolized hepatically by the enzymes of the cytochrome p450 enzyme system. Thalidomide does not appear to induce or inhibit its own metabolism. However, it may interfere with enzyme induction caused by other compounds. The end product of metabolism, phthalic acid, is excreted as a glycine conjugate.

The chiral inversion and hydrolysis of thalidomide and the catalysis by bases and human serum albumin were investigated by /utilizing/ a stereoselective HPLC assay. Chiral inversion was catalyzed by albumin, hydroxyl ions, phosphate and amino acids. Basic amino acids (arginine and lysine) had a superior potency in catalyzing chiral inversion compared to acid and neutral ones. The chiral inversion of thalidomide is thus subject to specific and general base catalysis and it is suggested that the ability of HSA to catalyze the reaction is due to basic groups of the amino acids arginine and lysine and not to a single catalytic site on the macromolecule. The hydrolysis of thalidomide was also base catalyzed. ... Albumin had no effect on hydrolysis and there was no difference between the catalytic potencies of acidic, neutral and base amino acids. ... Chiral inversion is deduced to occur by electrophilic substitution involving specific and general base catalysis, whereas hydrolysis is thought to occur by nucleophilic substitution involving specific and general base as well as nucleophilic catalysis. As nucleophilic attack is sensitive to steric properties of the catalyst, steric hindrance might be the reason albumin is not able to catalyze hydrolysis. (1)H NMR experiments revealed that the three teratogenic metabolites of thalidomide, in sharp contrast to the drug itself had complete chiral stability. This leads to the speculation that, were some enantioselectivity to exist in the teratogenicity of thalidomide, it could result from fast hydrolysis to chirally stable teratogenic metabolites.

Thalidomide has been shown to be an inhibitor of angiogenesis in a rabbit cornea micropocket model; however, it has failed to demonstrate this activity in other models. These results suggest that the anti-angiogenic effects of thalidomide may only be observed following metabolic activation of the compound. This activation process may be species specific, similar to the teratogenic properties associated with thalidomide. Using a rat aorta model and human aortic endothelial cells, we co-incubated thalidomide in the presence of either human, rabbit, or rat liver microsomes. These experiments demonstrated that thalidomide inhibited microvessel formation from rat aortas and slowed human aortic endothelial cell proliferation in the presence of human or rabbit microsomes, but not in the presence of rat microsomes. In the absence of microsomes, thalidomide had no effect on either microvessel formation or cell proliferation, thus demonstrating that a metabolite of thalidomide is responsible for its anti-angiogenic effects and that this metabolite can be formed in both humans and rabbits, but not in rodents. /There are five primary metabolites of thalidomide [4-OH-thalidomide, 3-OH-thalidomide, 39-OH-thalidomide, 49-OH-thalidomide, and 59-OH-thalidomide], and the antiangiogenic property could be the result of either of these compounds, or of an intermediate. Also, thalidomide undergoes rapid spontaneous hydrolysis in aqueous solutions at a pH of 6.0 or greater to form three primary products [4-phthalimidoglutaramic acid, 2-phthalimidoglutaramic acid, and a-(o-carboxybenzamido) glutarimide] and eight minor products. Furthermore, each of the five metabolites of the parent compound undergoes similar hydrolysis./

Three CD-1 mice were dosed orally with 3000 mg/kg thalidomide in 1% carboxymethylcellulose daily for three days and plasma samples were obtained 2, 4 and 6 hours postdose on the third day. Extracts of mouse plasma from thalidomide treated mice contained at least four components that absorbed at 230 nm, not observed in control plasma extracts. The first two components did not match any standards and may represent other metabolites, possibly hydrolysis products of thalidomide. The second pair of components closely matched standards for 4-hydroxythhalidomide and thalidomide respectively.

The mean half-life of elimination ranges from approximately 5 to 7 hours following a single dose and is not altered upon multiple dosing.
... The pharmacokinetics and hemodynamic effects of two oral doses of thalidomide (100 and 200 mg) were investigated, using a randomized two period crossover design, in a group of asymptomatic male HIV seropositive subjects. Thalidomide pharmacokinetics were linear at the doses studied, and were best described by a one compartment model with first order absorption and elimination processes. The drug was rapidly absorbed with a mean absorption half life of 0.95 hr (range 0.16-2.49 hr) and 1.19 hr (0.33-3.53 hr) after 100 and 200 mg doses, respectively. The corresponding Cmax values were 1.15 +/-0.24 ug/mL (100 mg) and 1.92 +/- 0.47- ug/mL (200 mg; p<0.001) which were achieved (Tmax) at 2.5 +/-1.5 hr and 3.3 +/-1.4 hr, respectively. Plasma concn of thalidomide declined thereafter, in a log linear manner, with elimination half lives of 4.6+/-1.2 hr (100 mg) and 5.3+/-2.2 hr -(200 mg). The apparent volumes of distribution (Vdss/F) were 69.9+/-1.56 L (100 mg) and 82.7+/-34.9 L (200 mg) while total body clearances (C1F) were 10.4+/-2.1 and 10.8+/- 1.7 L/hr, respectively. ...

The mean elimination half-life of thalidomide following a single 200-mg oral dose ranges from 3-6.7 hours and the elimination half-life appears to be similar following multiple doses of the drug. In a study in healthy adults who received a single 50-, 200-, or 400-mg oral dose of the drug, the mean elimination half-life of thalidomide was 5.5, 5.5, or 7.3 hours, respectively. The mean elimination half-life of thalidomide was 6.9 hours in adults with leprosy who received a single 400-mg oral dose and 4.6-6.5 hours in HIV-infected adults who received a single 100- to 300-mg dose.

In patients with erythema nodosum leprosum (ENL) the mechanism of action is not fully understood. Available data from in vitro studies and preliminary 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-a) 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-a in patients with ENL, however, it has also been shown to increase plasma TNF-a levels in HIV-seropositive patients. As a cancer treatment, the drug may act as a VEGF inhibitor.
The sedative drug thalidomide ([+]-alpha-phthalimidoglutarimide), once abandoned for causing birth defects in humans, has found new therapeutic license in leprosy and other diseases, with renewed teratological consequences. Although the mechanism of teratogenesis and determinants of risk remain unclear, related teratogenic xenobiotics are bioactivated by embryonic prostaglandin H synthase (PHS) to a free-radical intermediates that produce reactive oxygen species (ROS), which cause oxidative damage to DNA and other cellular macromolecules. Similarly, thalidomide is bioactivated by horseradish peroxidase, and oxidizes DNA and glutathione, indicating free radical-mediated oxidative stress. Furthermore, thalidomide teratogenicity in rabbits is reduced by the PHS inhibitor acetylsalicylic acid, indicating PHS-catalyzed bioac
