IND Submission to FDA for IW-2143 (BNC210) Anti-Anxiety Drug Candidate

  *Bionomics' licensee Ironwood Pharmaceuticals has submitted an
    Investigational New Drug application to the US Food & Drug Administration
  *IND is a precursor to proceeding with clinical trials on IW-2143 in the US

ADELAIDE, Australia, Nov. 8, 2012 (GLOBE NEWSWIRE) -- Bionomics Limited
(ASX:BNO) (ADR:BMICY) has been advised by its licensee Ironwood
Pharmaceuticals Inc that an Investigational New Drug (IND) application was
submitted to the US Food and Drug Administration (FDA) for a clinical trial of
anti-anxiety drug candidate IW-2143.

Ironwood intends to initiate Phase I studies with IW-2143 in healthy
volunteers following the filing of the IND by the FDA. The initial Phase I US
trial is designed to further assess IW-2143's pharmacokinetics.

"Ironwood has a strong team that has developed a thorough clinical development
program for IW-2143," said CEO and Managing Director of Bionomics Dr Deborah

Preclinical studies conducted by Bionomics suggest that IW-2143 has
anti‐anxiety activity and promotes neurite outgrowth.

In the US alone, anxiety disorders affect 40 million Americans each year and
while there are therapies available, there remains a significant unmet need.
IW-2143 has the potential to fill a need in this market as an anxiety drug
that may not have the sedation, withdrawal syndrome or memory impairment
reported with other therapies.

About IW-2143 (BNC210)

IW-2143 is a novel small molecule discovered by Bionomics through a targeted
medicinal chemistry program. Data from several preclinical studies indicate
that IW-2143 has anti-anxiety activity and promotes neurite outgrowth in
vitro. In a phase I study that included placebo and lorazepam control arms,
healthy volunteers who took IW-2143 did not appear to have impaired attention.
Electroencephalography (EEG) data gathered on healthy subjects dosed with
IW-2143 in the study provided evidence of a pharmacodynamic effect.
