Debiopharm begins Phase II trial for a once daily oral formulation of ZT-1

4-May-2011

For the treatment of Alzheimer\'s disease

Lausanne-based Debiopharm is to start a Phase II trial this year for dose-finding and efficacy assessment of a once daily oral formulation of ZT-1, a novel cholinesterase inhibitor, for the treatment of Alzheimer\'s disease (AD).

The multicentre trial will be conducted in France, Belgium and Switzerland, and will enroll 180 patients suffering from mild to moderate AD.

ZT-1\'s dual pharmacological mechanism of action offers the potential to slow deterioration, while improving cognitive function. In addition to its established anti-acetylcholinesterase (AChE) activity, ZT-1 has neuroprotective properties, one of them being mediated possibly by the N-methyl-D-aspartate (NMDA) receptor. After oral administration, ZT-1 is progressively hydrolysed into the active compound huperzine A (hup A). Hup A is one of the most potent AChE inhibitors and was originally isolated by Chinese scientists from the club moss Huperzia serrata.

Debiopharm is currently developing an injectable sustained-release formulation of ZT-1. The pharmacokinetic results in animals showed a stable release pattern over several weeks. This confers the potential to further benefit AD patients due to improved compliance and a close medical follow-up with monthly injections.
