Sector Watch: An apple, or pill, a day

Bette Davis once said “old age is no place for sissies,” and to a degree, she was right. Old age not only brings wrinkles, but serious diseases such as Alzheimer’s and diabetes. Two drug companies that want to make the transition into your golden years a bit more tolerable are Transition Therapeutics Inc. (Nasdaq:TTHI) and Sirtris Pharmaceuticals Inc. (Nasdaq:SIRT).

Both companies have ample cash for funding further development efforts and have made noteworthy progress over the last year advancing lead compounds. While Transition and Sirtris are likely several years away from commercial sales, their drug candidates address huge, growing markets, estimated at hundreds of millions of patients worldwide, and have significant future revenue potential. 

Transition is developing novel drugs for treating Alzheimer’s disease and Type 2 diabetes. Its lead compound, ELND005, for the treatment of Alzheimer’s disease, works by breaking down neurotoxic fibrils in the brain and allowing certain peptides to clear the body before they can form plaque. Alzheimer’s disease is the fourth leading cause of death among U.S. adults and has no cure; it begins with memory loss and eventually progresses to overall loss of cognitive function. Most Alzheimer’s patients die within eight years of diagnosis. More than 30 million people worldwide currently suffer from the disease and their numbers are expected to increase dramatically as the number of seniors grows.

The company is partnering with Elan Corporation (NYSE:ELN) to develop and commercialize ELND005. Phase II clinical trials of the drug involving some 340 patients with mild to moderate Alzheimer’s disease began last December and are expected to last approximately 18 months. To help fund the trials, Transition received milestone payments from Elan totaling $7.5 million last October and $5 million this January.

Transition is also developing TT-223 for the treatment of Type 2 diabetes. TT-223 works by regenerating the body’s insulin-producing cells. Diabetes is the world’s fastest-growing disease; there are more than 200 million diabetics worldwide and it is estimated one in 10 patients will eventually die from complications of the disease. Type 2 diabetes accounts for 90% of all cases and usually develops in adulthood. Transition is partnering with Eli Lilly & Co. (NYSE:LLY) to develop and . . .
