SYDNEY, Feb. 2, 2017 /PRNewswire/ -- Benitec Biopharma Limited (ASX:BLT; NASDAQ:
BNTC; NASDAQ: BNTCW) is pleased to announce today that it has made significant progress with the Company's ddRNAi technology for
the development of therapeutics for the treatment of ocular diseases. Of particular importance is the output from Benitec's
collaboration with 4D Molecular Therapeutics to identify novel viral vectors for delivery to the back of the eye using direct
intravitreal injection, a commercially attractive route of administration.
- Data to be presented at industry leading conferences
The results of this work will be presented by Dr David Suhy, Benitec's Chief Scientific
Officer, at the Association for Research in Vision and Ophthalmology (ARVO)-Asia meeting being
held in Brisbane on February 5th to February 8th, and the Translational Vision Summit (TVS), being held in conjunction. ARVO-Asia
is a leading conference dedicated to eye and vision research in the Asia-Pacific region. The TVS
meeting highlights "revolutionary approaches to advancing innovation in the diagnosis and treatment of eye disease".
- Development of novel viral vectors for delivery to the back of the eye
Dr David Suhy commented, "Having a commercially attractive route of administration is a
significant step forward in the program. One of the major limitations of most ocular gene therapy applications is the use
of a highly complex surgical technique called subretinal injection for delivery into the eye. We are developing viral vectors
which can efficiently transduce cells within the retina following an office-friendly, intravitreal injection. This is the
same route of administration used for the standard of care treatments for Age-Related Macular Degeneration (AMD), including
Lucentis® and Eylea®.
- Expanded potential of developing ddRNAi technology into ocular indications
David continued, "Being able to deliver drugs in therapeutically relevant concentrations is a key challenge in drug
development. It has taken significant time and effort, but we believe that these outcomes demonstrate the commercial
applicability of having a vector that can transduce the retina following an intravitreal injection. The AMD program is our
first program in this space and we anticipate being able to build a ddRNAi franchise for other ocular indications, in particular
retinal diseases, using these novel viral vectors as a key component in that platform."
Benitec's ddRNAi technology is a unique combination of gene silencing using RNA interference coupled with the long term
therapeutic activity of gene therapy vectors. The lead ocular candidate, BB-201, is designed to treat patients with the wet form
of AMD and will be featured in the ARVO-Asia presentations.
As a gene therapy approach, BB-201 has been designed for long term expression of the therapeutic short hairpin RNA from a
single injection. BB-201 is comprised of a novel adeno associated virus capsid (AAV) and a recombinant DNA cassette
engineered to express steady state levels of three short hairpin RNA (shRNA) that inhibit VEGF-a, VEGF-b and PlGF, three
clinically validated targets whose expression is shown to lead to the progression of the disease.
The full presentation will be posted on the Benitec website.

About Age-Related Macular Degeneration (AMD):
AMD is a disease that has been estimated to account for 8% of blindness worldwide and has been projected to impact up
to 196 million patients by 2020 and up to 288 million by 2040. The wet form of the disease accounts for about 10% of all
AMD patients but accounts for up to 90% of all the blindness. The wet form of the disease is characterised by the growth of new
blood vessels into the eye, a phenomenon that has been associated with the abnormally high expression of abnormally high levels
of proteins from the vascular endothelial growth factor (VEGF) family. The most commonly used standard of care treatments for AMD
require an intravitreal injection into the eye as frequently as monthly or bi-monthly. Such injections may be required
indefinitely to be able to halt progression of the disease and stabilise vision.
About Benitec Biopharma Limited:
Benitec Biopharma Limited (ASX: BLT; NASDAQ: BNTC; NASDAQ: BNTCW) is a biotechnology company developing innovative
therapeutics based on its patented gene-silencing technology called ddRNAi or 'expressed RNAi'. Based in Sydney, Australia with laboratories in Hayward, California (USA), and
collaborators and licensees around the world, the company is developing ddRNAi-based therapeutics for chronic and
life-threatening human conditions including hepatitis B, wet age-related macular degeneration and OPMD. Benitec has also licensed
ddRNAi to other biopharmaceutical companies for applications including HIV/AIDS, Huntington's Disease, chronic neuropathic pain,
cancer immunotherapy and retinitis pigmentosa.
