O'Neil, M.J. (ed.). The Merck Index - An Encyclopedia of Chemicals, Drugs, and Biologicals. 13th Edition, Whitehouse Station, NJ: Merck and Co., Inc., 2001., p. 203


Bexarotene is indicated for the treatment of cutaneous manifestations of cutaneous T-cell lyphoma in patients who are refractory to at least one other prior systemic therapy. /Included in US product label/

Thomson/Micromedex. Drug Information for the Health Care Professional. Volume 1, Greenwood Village, CO. 2006., p. 615


4.3 Drug Warning

May cause fetal harm; teratogenicity and embryolethality demonstrated in animals. No adequate and well-controlled studies to date in humans. Pregnancy should be avoided during therapy. If used during pregnancy, apprise of potential fetal hazard. ... Male patients receiving the drug should use condoms during sexual intercourse with women who are or may become pregnant.

McEvoy, G.K. (ed.). American Hospital Formulary Service. AHFS Drug Information. American Society of Health-System Pharmacists, Bethesda, MD. 2006., p. 939


Effective contraception must be used for one month prior to the initiation of therapy, during therapy and for at least one month following discontinuation of therapy; it is recommended that two reliable forms of contraception be used simultaneously unless abstinence is the chosen method. Bexarotene can potentially induce metabolic enzymes and thereby theoretically reduce the plasma concentrations of oral or other systemic hormonal contraceptives.

Physicians Desk Reference 60th ed, Thomson PDR, Montvale, NJ 2006., p. 1720


Hyperlipidemia occurred in 79% of patients receiving oral bexarotene in phase II-III clinical studies. Elevations in fasting triglycerides and cholesterol and decreases in HDL-cholesterol were observed in more than half of patients receiving 300 mg/sq m or more. Lipid abnormalities usually developed within 2-4 weeks and were reversible with cessation of therapy. If fasting triglycerides are elevated or become elevated during treatment, antilipemic therapy should be instituted, and the dosage of bexarotene reduced or suspended.

McEvoy, G.K. (ed.). American Hospital Formulary Service. AHFS Drug Information. American Society of Health-System Pharmacists, Bethesda, MD. 2006., p. 939


Acute pancreatitis has been reported in several patients treated with bexarotene and has been fatal in at least one patient. The manufacturer states that patients with cutaneous T-cell lymphoma (CTCL) who have risk factors for pancreatitis (eg, prior pancreatitis, uncontrolled hyperlipidemia, excessive alcohol consumption, uncontrolled diabetes mellitus, biliary tract disease, or drugs associated with pancreatic toxicity or known to increase triglyceride concentrations) generally should not be treated with bexarotene.

4.4 Drug Indication

Used orally for the treatment of skin manifestations of cutaneous T-cell lymphoma (CTCL) in patients who are refractory to at least one prior systemic therapy. Also used topically for the treatment of skin lesions in early (stage IA and IB) CTCL in patients who experience refractory or persistent disease with the use of other therapies or are intolerant of other therapies.


FDA Label


Targretin capsules are indicated for the treatment of skin manifestations of advanced stage cutaneous T-cell lymphoma (CTCL) patients refractory to at least one systemic treatment.


5 Pharmacology and Biochemistry
5.1 Pharmacology

Bexarotene is a member of a subclass of retinoids that selectively activate retinoid X receptors (RXRs). These retinoid receptors have biologic activity distinct from that of retinoic acid receptors (RARs). Bexarotene is indicated for the treatment of cutaneous manifestations of cutaneous T-cell lymphoma in patients who are refractory to at least one prior systemic therapy. Bexarotene selectively binds and activates retinoid X receptor subtypes (RXR, RXR, RXR). RXRs can form heterodimers with various receptor partners such as retinoic acid receptors (RARs), vitamin D receptor, thyroid receptor, and peroxisome proliferator activator receptors (PPARs). Once activated, these receptors function as transcription factors that regulate the expression of genes that control cellular differentiation and proliferation. Bexarotene inhibits the growth in vitro of some tumor cell lines of hematopoietic and squamous cell origin. It also induces tumor regression in vivo in some animal models.

5.5 Absorption, Distribution and Excretion

Route of Elimination

Urinary elimination of bexarotene and its known metabolites is a minor excretory pathway (<1% of administered dose).


After oral administration, bexarotene is absorbed with a Tmax of about two hours. ...Studies in patients with advanced malignancies show approximate single dose linearity within the therapeutic range and low accumulation with multiple doses. Plasma bexarotene AUC and Cmax values resulting from a 75 to 300 mg dose were 35% and 48% higher, respectively, after a fat-containing meal than after a glucose solution. Bexarotene is highly bound (>99%) to plasma proteins. The plasma proteins to which bexarotene binds have not been elucidated, and the ability of bexarotene to displace drugs bound to plasma proteins and the ability of drugs to displace bexarotene binding have not been studied.

Physicians Desk Reference 60th ed, Thomson PDR, Montvale, NJ 2006., p. 1719


The renal elimination of bexarotene and its metabolites was examined in patients with Type 2 diabetes mellitus. Neither bexarotene nor its metabolites were excreted in urine in appreciable amounts. Bexarotene is thought to be eliminated primarily through the hepatobiliary system.

Physicians Desk Reference 60th ed, Thomson PDR, Montvale, NJ 2006., p. 1719


5.6 Metabolism/Metabolites

Four bexarotene metabolites have been identified in plasma: 6- and 7-hydroxy-bexarotene and 6- and 7-oxo-bexarotene. In vitro studies suggest that cytochrome P450 3A4 is the major cytochrome P450 responsible for formation of the oxidative metabolites and that the oxidative metabolites may be glucuronidated. The oxidative metabolites are active in in vitro assays of retinoid receptor activation, but the relative contribution of the parent and any metabolites to the efficacy and safety of /bexarotene/ is unknown.

Physicians Desk Reference 60th ed, Thomson PDR, Montvale, NJ 2006., p. 1719


Bexarotene has known human metabolites that include 6-hydroxy-bexarotene, 7-hydroxy-bexarotene, and 7-oxo-bexarotene.

5.7 Biological Half-Life

7 hours


Terminal half-life of bexarotene is about seven hours.

Physicians Desk Reference 60th ed, Thomson PDR, Montvale, NJ 2006., p. 1719


5.8 Mechanism of Action

Bexarotene selectively binds with and activates retinoid X receptor subtypes. There are three subtypes in total: RXR, RXR, RXR. The exact mechanism of action of bexarotene in the treatment of CTCL is unknown but the drug has activity in all clinical stages of CTCL.


Bexarotene selectively binds and activates retinoid X receptor subtypes (RXR(alpha), RXR(beta), RXR(gamma)). RXRs can form heterodimers with various receptor partners such as retinoic acid receptors (RARs), vitamin D receptor, thyroid receptor, and peroxisome proliferator activator receptors (PPARs). Once activated, these receptors function as transcription factors that regulate the expression of genes that control cellular differentiation and proliferation. Bexarotene inhibits the growth in vitro of some tumor cell lines of hematopoietic and squamous cell origin. It also induces tumor regression in vivo in some animal models. The exact mechanism of action of bexarotene in the treatment of cutaneous T-cell lymphoma (CTCL) is unknown.
