Scientists working on a new obesity drug program at Denmark's 7TM
Pharma say they've seen dramatic weight loss in rodents treated with a
second-generation cannabinoid receptor blocker. And they say that they
could be on to a successor to rimonabant, also known as Acomplia, which
was yanked from the European market two years ago due to the troubling
risk of psychiatric side effects.
This new drug, TM38837, is designed to work in human tissue and
organs, but not the brain. This is where rimonabant ran into trouble--a
number of patients on Acomplia complained of severe depression and
suicidal thoughts. In fact, the experimental therapy looks just as
effective as rimonabant in trimming weight. In mice, the drug was
associated with a 22 percent to 26 percent drop in body weight
compared with a placebo. Furthermore, drug-treated rats had 14 percent
lower body weights than placebo-treated rats, PhysOrg reports.
