Bionomics Limited Advances BNC210, Anti-anxiety Lead Candidate

Published: Mar 11, 2008

Adelaide, Australia: Bionomics Limited (ASX: BNO) today announced the commencement of its formal safety and tolerability evaluation program in animals of BNC210, Bionomics’ anti-anxiety lead candidate.

The commencement of this program is a key milestone in the drug development process, with Bionomics on track to submit an Investigational New Drug (IND) application with the US Food and Drug Administration (FDA) by late 2008. The Company will use the results of the program to identify a safe starting dose in humans for clinical trials estimated to commence in the first half of 2009.

Dr Deborah Rathjen, Bionomics CEO & Managing Director said, “We are excited to commence these studies with anti-anxiety lead, BNC210. Our plans for BNC210 closely follow the path to clinical trial already established by our lead anti-cancer candidate BNC105, which commenced Phase I trials last week.”

This series of safety and tolerability studies is being conducted by WIL Research Laboratories, LLC, in Ashland, Ohio (USA) a contract research organization recognized worldwide for conducting quality Good Laboratory Practice (GLP) studies in line with FDA requirements.

“Our goal is to complete an IND submission at the end of this calendar year and we’re planning for a pre-IND meeting with the FDA in mid-2008,” continued Dr Rathjen.

BNC210 is a novel compound generated from Bionomics’ powerful medicinal chemistry platform technology. It was the best performing anxiety drug candidate out of a focussed library of compounds that were synthesized, evaluated and tested in a range of small animal models.

The Anxiety program leader, Dr Sue O’Connor commented, “WIL Research Laboratories, LLC is a contract research organisation (CRO) that provides toxicology, pharmacology, metabolism, and bio-analytical services to the pharmaceutical industry. They have a long-standing, strong reputation within the scientific community and we are looking forward to working with them to assess the safety and tolerability of BNC210 in the lead up to our IND submission.”

Preclinical data shows that in animals BNC210 is able to reduce anxiety without the common side effects of current anxiety drugs including drowsiness, impairment of memory and motor function. In addition, BNC210 was shown to be fast-acting and effective with a single daily dose.

Anxiety is a common debilitating condition that affects 19 million patients in the US alone, and has an estimated market value $5-$12 billion worldwide. Many of the largest blockbuster drugs are for treating anxiety including Valium, Prozac, Paxil, Buspar and Zoloft. The issue is that most of the current anxiety therapeutics are not ideal and have a range of side effects, including sedation and loss of memory.
