Thalidomide may fight blood vessel disorder: Nosebleeds eased with once-maligned drug

April 05, 2010 – A very recent article by msnbc.com indicates that thalidomide, a drug that caused birth defects when it was launched as a morning sickness pill half a century ago, may be useful for treating a hereditary condition that affects blood vessels.

In a study in the journal Nature Medicine, French researchers found giving thalidomide to patients with a disorder called hereditary hemorrhagic telangiectasia (HHT) reduced the severity and frequency of nosebleeds, one of the main symptoms.

Franck Lebrin, who led the study with colleagues from the National Institute for Health and Medical Research in Paris, said experiments on mice with HHT showed thalidomide treatment was able to repair blood vessel wall defects through a mechanism involving proteins involved in cell growth. “Biopsies of the nasal surface tissue from patients with HHT showed that similar mechanisms may explain the effects of thalidomide treatment in humans,” he wrote in the study.

HHT affects about one in 5,000 people. Many patients develop recurrent, difficult-to-treat nosebleeds which can significantly harm their quality of life.

Thalidomide was used to treat nausea during pregnancy in the 1960s. The drug was taken off the market after severe teratogenic congenital defects appeared in the newborns of mothers who had taken it (referred to as “contergan scandal” in germany).

More recently, thalidomide – which has powerful anti-cancer properties – experienced a revival and is now being used to treat certain forms of cancer such as multiple myeloma, and the drug is on the market in the US as Thalidomide [Thalomed]. U.S. drugmaker Celgene has developed a successor drug to thalidomide, called Lenalidomide [Revlimid], which is also approved to treat multiple myeloma.
