ExonHit announces publication of EHT 0202 Phase IIa results in Current Alzheimer Research
Data show good safety and tolerability in patients
Efforts are ongoing to pursue EHT 0202 development in Phase IIb either through partnering or alternative financing
under the supervision of Professor Bruno Vellas, Head of the Alzheimer’s Disease Clinical Research Center and of the Gérontopôle, Toulouse University Hospital, France. A total of 197 ambulatory patients 60 to 90 years old and suffering from mild to moderate Alzheimer’s disease were selected and 159 of them were randomized to receive oral study treatment over a three-month period.
About EHT 0202
EHT 0202 is ExonHit’s lead candidate in Alzheimer’s disease and potentially first in a new class of disease modifying therapies which stimulate
Phase I studies demonstrated good tolerability of EHT 0202 in both young and aged healthy volunteers.
Preclinical studies have shown that EHT 0202 protects cortical neurons against Aâ42-induced toxicity and that this neuroprotection is associated with sAPPá induction. EHT 0202 has also demonstrated procognitive properties in several animal models: age-related memory impairment and scopolamine-induced amnesia (3).
Alzheimer’s disease is a progressive neurodegenerative condition that is the most frequent cause of dementia in the elderly. It is a disease of multifactorial origin that involves environmental and genetic factors. Worldwide, an estimated 26.6 million people had Alzheimer’s disease in 2006. This number is set to quadruple by 2050 to more than 100 million; 1 in 85 people worldwide will be living with the disease (4). In France alone, 800,000 people, or 18% of the population over-75, have Alzheimer’s disease (5).http://www.exonhit.com.

Paris, France – April 4, 2011 -
"The publication of these promising first patient data in a peer-reviewed Alzheimer’s disease journal highlights the interest of the Alzheimer’s scientific community in our EHT 0202 compound. Such interest further supports our efforts to pursue the development of EHT 0202 in Phase IIb either through partnering or alternative financing,"
said Matthew Pando, PhD, Executive Vice President, Therapeutics of ExonHit Therapeutics. "We have also identified several potential biomarkers, including response signatures using our GWSA platform that will strengthen the likelihood of success in future EHT 0202 clinical trials."
The study was conducted in 23 centers across France
This randomized, double-blind, placebo-controlled study was designed to assess the clinical safety and tolerability, as a primary objective, and also exploratory efficacy of EHT 0202 in patients with Alzheimer’s disease. The effect of two different doses of EHT 0202 (either 40 or 80 mg twice a day) as adjunctive therapy to one acetylcholinesterase inhibitor was evaluated in comparison to placebo.
ExonHit Therapeutics (Alternext: ALEHT) today announced the publication of Phase IIa results for EHT 0202, its lead candidate for the treatment of Alzheimer’s disease, in the journal Current Alzheimer Research. Study data demonstrate good safety and tolerability of EHT 0202 hence supporting its advancement into Phase IIb to assess clinical efficacy and confirm tolerability in a larger cohort of Alzheimer’s patients over a longer treatment duration (1).
