Neurovance Receives Notice of Allowance for Composition of Matter Patent and Initiates Clinical Trial of New SR Formulation of EB-1020


2/21/2013 10:52:42 AM

Cambridge, MA – February 21, 2013 – Neurovance, Inc. today announced that the United States Patent and Trademark Office (USPTO) has issued a notice of allowance for a composition of matter patent for EB-1020. The patent provides Neurovance with proprietary protection for EB-1020 through July 2026. Neurovance also said that it has initiated a phase 1 clinical trial of EB-1020 with a new sustained-release (SR) formulation to treat adult attention deficit hyperactivity disorder (ADHD).

EB-1020 is being developed to improve efficacy compared to existing non-stimulants, but to do so with less risk of abuse liability and diversion, or non-medicinal use, than the current stimulants (amphetamine and amphetamine-like medications) that are the standard of care in ADHD. This phase 1 “umbrella” study will evaluate pharmacokinetics, food effects, and tolerability of a sustained-release formulation with multiple dose escalation in healthy volunteers. Results are expected during the second quarter, with plans for a phase 2a pilot study in the US later this year. According to IMS Health, the US ADHD market in 2011 was valued at $7.9 billion with significant growth coming from the adult segment of the market.

This follows recent completion by Neurovance of an initial phase 1 clinical trial of EB-1020 that evaluated single and multiple ascending doses in normal subjects. EB-1020 was well tolerated and safe across a broad dose range. However, the study also showed the plasma half-life of the immediate-release (IR) formulation was likely too short for optimal use in ADHD. Following that study, Neurovance developed sustained-release formulations of EB-1020 to improve dosing convenience for adults with ADHD.

Anthony A. McKinney, President and CEO of Neurovance, noted, "Taken together, these developments combine to significantly support the value of EB-1020. The US composition of matter patent is a critically important milestone, and with initiation of this phase 1 trial using the SR formulation, we have taken another step towards the treatment of adult ADHD. This sets the stage for our near-term plans to move beyond healthy volunteers and into patients in a phase 2a trial that should be initiated this fall."

EB-1020 is being developed for adult ADHD based on its potent norepinephrine (NE) reuptake inhibition, combined with moderate dopamine (DA) reuptake inhibition and very modest serotonin (5-HT) reuptake inhibition. EB-1020 has a norepinephrine profile similar to the pharmacology of the first-generation non-stimulant atomoxetine, but unlike atomoxetine, EB-1020 adds moderate dopamine neurotransmission that is believed to offer the potential for improved efficacy in ADHD. The level of dopamine activity associated with EB-1020 is less than that of stimulants – an important distinction because stimulants are addictive because they greatly activate dopamine neurotransmission, resulting in these Schedule II products (i.e. controlled substances) being tightly regulated by the government. By contrast, EB-1020 may have a lower risk of drug abuse liability and diversion, as suggested by preclinical and clinical data to-date.

The phase 1 umbrella trial is being conducted on behalf of Neurovance by INC Research and Nucleus Network in Melbourne, Australia.
