Thalidomide Celgene

Thalidomide Celgene Uses, Dosage, Side Effects, Food Interaction and all others data.

Thalidomide Celgene is a synthetic glutamic acid derivative immunomodulator with anti-inflammatory, antiangiogenetic, sedative and hypnotic activity.

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.

Thalidomide Celgene is an immunomodulatory agent with a spectrum of activity that is not fully characterized. Thalidomide Celgene 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.

Uses

Multiple Myeloma: Thalidomide Celgene in combination with dexamethasone is used for the treatment of patients with newly diagnosed multiple myeloma (MM).

Erythema Nodosum Leprosum: Thalidomide Celgene is used for the acute treatment of the cutaneous manifestations of moderate to severe erythema nodosum leprosum (ENL). Thalidomide Celgene is not used as monotherapy for such ENL treatment in the presence of moderate to severe neuritis. Thalidomide Celgene is also used as maintenance therapy for prevention and suppression of the cutaneous manifestations of ENL recurrence

Thalidomide Celgene is also used to associated treatment for these conditions: Chronic Graft Versus Host Disease, Multiple Myeloma (MM), Stomatitis, Aphthous, Uremic Pruritus, Waldenström's Macroglobulinemia (WM), Advanced Systemic light chain amyloidosis, Moderate Erythema nodosum leprosum, Refractory Graft versus host disease, Severe Erythema nodosum leprosum, Treatment naive multiple myeloma

Dosage

Thalidomide Celgene dosage

Multiple Myeloma: Thalidomide Celgene is administered in combination with dexamethasone in 28-day treatment cycles. The dose of Thalidomide Celgene is 200 mg administered orally once daily 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.

Patients who develop adverse reactions such as constipation, somnolence, or peripheral neuropathy may benefit by either temporarily discontinuing the drug or continuing at a lower dose. With the abatement of these adverse reactions, the drug may be started at a lower dose or at the previous dose based on clinical judgment. Erythema Nodosum Leprosum: For an episode of cutaneous ENL, Thalidomide Celgene dosing should be initiated at 100 to 300 mg/day, administered once daily with water, preferably at bedtime and at least 1 hour after the evening meal. Patients weighing less than 50 kilograms should be started at the low end of the dose range.

In patients with a severe cutaneous ENL reaction, or in those who have previously required higher doses to control the reaction, Thalidomide Celgene dosing may be initiated at higher doses up to 400 mg/day once daily at bedtime or in divided doses with water, at least 1 hour after meals.

In patients with moderate to severe neuritis associated with a severe ENL reaction, corticosteroids may be started concomitantly with Thalidomide Celgene. Steroid usage can be tapered and discontinued when the neuritis has ameliorated.

Dosing with Thalidomide Celgene should usually continue 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.

Side Effects

Severe and irreversible peripheral neuropathy, constipation, dizziness, orthostatic hypotension, drowsiness, somnolence, bradycardia, increase of viral load in HIV-infected patients, hypersensitivity reaction.

Toxicity

The R-configuration and the S-configuration are more toxic individually than the racemic mixture. The LD50 could not be established in mice for racemic thalidomide, whereas LD50 values for the R and S configurations are reported to be 0.4 to 0.7 g/kg and 0.5 to 1.5 g/kg, respectively.

Precaution

All females of childbearing potential must use 2 reliable forms of contraception simultaneously 4 wk before starting therapy, during and 4 wk after therapy is discontinued. Therapy to be stopped immediately if pregnancy occurs. Male: Use of barrier methods of contraception if partner is of child-bearing potential. Do not donate blood or sperm during therapy. Patient should not drive or operate machinery. Discontinue therapy if any skin rash develops. Do not resume therapy if the rash is exfoliative, purpuric, or bullous, or if Stevens-Johnson syndrome or toxic epidermal necrolysis suspected

Interaction

Thalidomide Celgene enhances sedative activity of barbiturates, alcohol, chlorpromazine and reserpine. Avoid use of other drugs that have the potential to cause peripheral neuropathy. Increased risk of thromboembolic events with darbepoetin-alfa and doxorubicin.

Food Interaction

  • Avoid alcohol. Ingesting alcohol may increase the drowsiness caused by thalidomide.
  • Take after a meal. Wait at least 1 hour after eating before taking thalidomide.

[Moderate] GENERALLY AVOID: Alcohol may potentiate some of the pharmacologic effects of CNS-active agents.

Use in combination may result in additive central nervous system depression and
MANAGEMENT: Patients receiving CNS-active agents should be warned of this interaction and advised to avoid or limit consumption of alcohol.

Ambulatory patients should be counseled to avoid hazardous activities requiring complete mental alertness and motor coordination until they know how these agents affect them, and to notify their physician if they experience excessive or prolonged CNS effects that interfere with their normal activities.

Thalidomide Celgene Disease Interaction

Moderate: seizures, HIV infection, hypotension, neutropenia, peripheral neuropathy

Elimination Route

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.

Half Life

The mean half-life of elimination ranges from approximately 5 to 7 hours following a single dose and is not altered upon multiple dosing.

Elimination Route

Thalidomide Celgene itself has less than 0.7% of the dose excreted in the urine as unchanged drug.

Pregnancy & Breastfeeding use

Pregnancy Category X. Studies in animals or human beings have demonstrated foetal abnormalities or there is evidence of foetal risk based on human experience or both, and the risk of the use of the drug in pregnant women clearly outweighs any possible benefit. The drug is contraindicated in women who are or may become pregnant.

Contraindication

Pregnancy and lactation.
