2nd-generation Celexa, or TC-2216

Targacept is in the process of developing a “new class of [oral] drugs known as NNR (neuronal nicotinic receptor) Therapeutics.” They’re starting the first phase of a clinical trial called TC-2216 that targets depression and anxiety treatment.

“The trial is designed to evaluate the safety and tolerability of TC-2216 and to assess its pharmacokinetic profile. The trial is a double-blind, placebo-controlled crossover study, with sequential ascending single oral doses administered to healthy male volunteers.”

The next paragraph in the press release (basically) that I got this from goes on to explain that the new compound focuses in on the central nervous system and mood-regulating neurotransmitters, blah, blah, blah.

“In preclinical studies, TC-2216 showed greater potency than and anti-depressant effects comparable to selective serotonin reuptake inhibitors and tricyclics, which are commonly used treatments for depression, as well as anxiety-relieving effects.”

Because every new product in the clinical trial phase and has yet to receive FDA approval is better than everything currently out on the market. Of course.

“In November, the company announced positive top line results from a Phase II clinical trial of TRIDMAC, a treatment combination comprised of mecamylamine hydrochloride as an augmentation therapy to citalopram hydrobromide, in patients who did not respond adequately to citalopram alone. Mecamylamine hydrochloride binds non-selectively to various NNR subtypes, but there is a body of scientific evidence that suggests that its anti-depressant activity is derived through its antagonism at the alpha4beta2 NNR.”

What’s that mean? They’re basically working on Celexa II if people were treatment-resistant to the original Celexa. Like many other drug companies, they’re patenting a similar version of Celexa once Celexa’s eligible to become a generic brand.

“‘The results of our TRIDMAC trial not only substantiate the promise of the NNR mechanism in the treatment of depression and other mood disorders, but also further bolster our enthusiasm for the potential of TC-2216 said J. Donald deBethizy, Ph.D., Targacept’s President and Chief Executive Officer.’”

That’s a pretty bold statement for a company that’s just in Phase I of a clinical trial.
