Research and Markets: Targacept's TC-5619 - The prospects for this fully-owned alpha-7 neuronal nicotinic receptor agonist

Research and Markets
Posted on: 07 Jan 13

Research and Markets (http://www.researchandmarkets.com/research/g8jxmm/targacepts) has announced the addition of the "Targacept's TC-5619 - The prospects for this fully-owned alpha-7 neuronal nicotinic receptor agonist" report to their offering.

In 2011, Targacept reported that its phase II proof of concept study of TC-5619 in cognitive dysfunction in schizophrenia (CDS) met the pre-specified primary endpoint, while the trial in ADHD missed the primary endpoint but showed signals of drug activity. However, AstraZeneca subsequently decided not to exercise its option to license TC-5619, and Targacept retains full rights to the compound. The company plans to continue its development with a new phase IIb trial but with a slight change in direction.

In this report, we review the scientific rationale, the early safety and activity data as a means to gauge TC-5619's prospects in what is a huge market opportunity with a significant unmet need.
