• Bexarotene (LGD-1069) is a synthetic retinoid analog with specific affinity for the retinoid X receptor and belongs to a group of compounds called rexinoids.  It is an oral, noncytotoxic drug that was approved in Europe and in the U.S.A. for the treatment of refractory advanced-stage cutaneous T-cell lymphomas (CTCL).  Gniadecki, R., et al.  "The optimal use of bexarotene in cutaneous T-cell lymphoma."  Br. J. Dermatol. 157:  433-440 (2007).

• Compared with historical results with combination chemotherapy alone, bexarotene in combination with chemotherapeutic agents has showed an encouraging median survival for patients with advanced non-small cell lung cancer.  Rigas, J.R. and Dragnev, K.H.  "Emerging Role of Rexinoids in Non-Small Cell Lung Cancer: Focus on Bexarotene."  The Oncologist 10:  22-33 (2005).

• The receptor-selective retinoids might be particularly useful in preventing ER-negative breast cancer.  Wu, K., et al.  "The retinoid X receptor-selective retinoid, LGD1069, prevents the development of estrogen receptor-negative mammary tumors in transgenic mice."  Cancer Res. 62:  6376-6380 (2002).

• Results from cell culture treatments and in vivo xenograft models suggested that bexarotene in combination with chemotherapeutic agents might play an important role in preventing and overcoming acquired drug resistance in advanced prostate cancer, breast carcinoma, and non-small cell lung cancer.  Ye,n W.C. and Lamph, W.W.  "A selective retinoid X receptor agonist bexarotene (LGD1069, Targretin) prevents and overcomes multidrug resistance in advanced prostate cancer."  Prostate 66:  305-316 (2006).  Yen, W.C. and Lamph, W.W.  "The selective retinoid X receptor agonist bexarotene (LGD1069, Targretin) prevents and overcomes multidrug resistance in advanced breast carcinoma."  Mol. Cancer Ther. 4:  824-834 (2005).  Yen, W.C., et al.  "A selective retinoid X receptor agonist bexarotene (Targretin) prevents and overcomes acquired paclitaxel (Taxol) resistance in human non-small cell lung cancer."  Clin. Cancer Res. 10:  8656-8664 (2004).
