MUMBAI, India, and GERMANTOWN, USA, Oct. 1, 2013 /PRNewswire/ --Sun
Pharmaceutical Industries Ltd. (Reuters: SUN.BO, Bloomberg: SUNP IN, NSE:
SUNPHARMA, BSE: 524715), an international specialty pharmaceutical company
focused on chronic diseases, through its subsidiary, and Intrexon Corporation
(NYSE: XON), a leader in synthetic biology, today announced the formation of a
joint venture to develop controllable gene-based therapies for the treatment
of ocular diseases that cause partial or total blindness in millions of people
worldwide. Initial targets are dry age-related macular degeneration (AMD),
glaucoma and retinitis pigmentosa.

The joint venture will leverage Sun Pharma's global capabilities and
experience in developing and manufacturing complex dosage forms and specialty
pharmaceuticals for niche therapy areas. Intrexon and Sun Pharma will share in
both the financing of, and the revenues from, the joint venture.

Through an Exclusive Channel Collaboration (ECC), the joint venture will have
access to Intrexon's full suite of proprietary synthetic biology technologies,
including the RheoSwitch Therapeutic System^® (RTS^®) platform. RTS^® is a
clinically validated method for controlling the location, concentration and
timing of protein expression. RTS^® may address a long-standing limitation of
current approaches by enabling patients to receive a targeted biologic therapy
without having to endure a lifetime of injections.

In addition to the initial targets, the companies intend to further expand the
future pipeline of targeted ocular diseases to potentially include wet AMD,
macular edema, non-infectious uveitis and diabetic retinopathy.

Samuel Broder, M.D., Senior Vice President of Intrexon's Health Sector and
former Director of the National Cancer Institute, noted that current
treatments for major ocular disorders require frequent and often painful
interventions that, at best, only slow the progression of the disease.

"Using our RTS^® platform, the goal is to engineer a gene-based ocular
treatment in which the concentration, location and timing of protein
expression can be controlled with small molecule therapy," Dr. Broder said.
"In combination with Sun Pharma's tremendous development and manufacturing
experience, we hope to produce a therapy that is minimally invasive as well as
maximally effective in treating these debilitating diseases."

Dilip Shanghvi, Managing Director of Sun Pharma, said "We believe Intrexon's
biotechnology capabilities will enable us to develop not one, but several
highly effective, novel treatments for multiple ocular disorders where there
is currently an unmet need. Through this partnership it is our goal to
provide relief for millions of people who today have very few treatment
options and little hope of preserving their vision."

Randal J. Kirk, Chairman and Chief Executive Officer of Intrexon, said the
collaboration between Sun Pharma and Intrexon is a model relationship aligned
to accelerate development and production of new bio-engineered therapies.

"Today, more people suffer from ocular diseases than cancer," Kirk said. "To
address this immense unmet need, our innovative collaboration will unite Sun
Pharma's global capability to develop and manufacture complex pharmaceuticals
with Intrexon's proprietary cell and gene engineering technologies. We share
Sun Pharma's enthusiasm for the potential of our venture to produce a pipeline
of product opportunities aimed at well-validated therapeutic targets."
