Manufacture of BNC101 Commences at Lonza

ADELAIDE, South Australia, April 23, 2013 (GLOBE NEWSWIRE) -- Bionomics
Limited (ASX:BNO) (ADR:BMICY) announced today that it has initiated
manufacturing activities for BNC101, its lead anti-cancer stem cell candidate
following completion of key preclinical studies.

Dr Deborah Rathjen, Bionomics CEO & Managing Director commented, "The start of
manufacturing activities for BNC101 signals a significant step towards
clinical trials. We anticipate that Bionomics will commence clinical trials of
BNC101 in 2014".

"BNC101 is a novel therapeutic antibody designed to target cancer stem
cells.Eliminating cancer stem cells represents a new cancer treatment
paradigm that could offer a distinct advantage over existing treatment
strategies and a solution for resistance to chemotherapy," said Dr Rathjen.

Lonza will manufacture BNC101 at its facility in Slough, UK.

"We consider Lonza to be a leader in the area of contract development and
manufacturing, and we are pleased to announce this important milestone in the
BNC101 development program," said Christopher Reyes, Ph.D., Vice President of
Research and Development Biologics.

Preclinical data has shown that BNC101 has demonstrated functional activity
against LGR5, a high value cancer stem cell receptor. In addition, BNC101
significantly reduces cancer stem cell frequency and prevents tumour
re-growth in long term animal studies involving primary colorectal cancer
patient samples with multiple underlying gene mutations.

The clinical strategy for BNC101 will target solid tumours expressing LGR5
where there is a high rate of relapse. Colorectal cancer and pancreatic cancer
have been chosen as initial priority indications.

About Bionomics Limited

Bionomics (ASX:BNO) is an Australian based international biotechnology company
which discovers and develops innovative therapeutics for cancer and diseases
of the central nervous system. Bionomics has small molecule and antibody
product development programs in the areas of cancer, anxiety, and memory loss.
Its oncology approach includes cancer stem cell therapeutics as well as
vascular disruption in solid tumours.

BNC105, which is undergoing Phase II clinical development in a range of solid
tumour types,is based upon the identification of a novel compound that
potently and selectively restricts blood flow within tumours. BNC105 offers
blockbuster potential if successfully developed. A clinical program is also
underway for the treatment of anxiety disorders and depression based on
IW-2143(BNC210), a novel compound which stimulates neurite outgrowth. IW-2143
is partnered with Ironwood Pharmaceuticals.

Bionomics' discovery and development activities are driven by its four
proprietary technology platforms: Angene®, a drug discovery platform which
incorporates a variety of genomics tools to identify and validate novel
angiogenesis targets (involved in the formation of new blood vessels);
MultiCore®, a diversity orientated chemistry platform for the discovery of
small molecule drugs; ionX® , a set of novel technologies for the
identification of drugs targeting ion channels for diseases of the central
nervous system; and CSC Rx Discovery™, which identifies antibody and small
molecule therapeutics that inhibit the growth of cancer stem cells. These
platforms drive Bionomics' pipeline and underpin its established business
strategy of securing partners for its key compounds.
