Zogenix and Battelle Extend DosePro Co-Marketing Partnership

Zogenix and Battelle Extend DosePro Co-Marketing Partnership

SAN DIEGO and COLUMBUS, Ohio, March 27, 2013 (GLOBE NEWSWIRE) -- Zogenix, Inc.
(Nasdaq:ZGNX), a pharmaceutical company commercializing and developing
products for the treatment of central nervous system disorders and pain, and
Battelle, the world's largest independent research and development
organization, today announced they have extended their co-marketing
partnership for the DosePro® needle-free drug delivery system through March
29, 2014. The partnership is focused on advancing out-licensing opportunities
for DosePro, with a focus on co-marketing the technology to potential
biopharmaceutical and government clients.

William Dunlevy, Vice President and General Manager, Process and Product
Development at Battelle, said, "Over the course of the past year, we have
worked closely with Zogenix to develop and implement a focused co-marketing
campaign that highlights key attributes of the DosePro needle-free delivery
system. We have received positive feedback regarding our study of DosePro
delivery of a monoclonal antibody and our self-injection survey of patients
with rheumatoid arthritis. These findings clearly demonstrate the benefits and
capabilities of the DosePro system. This has driven strong interest in the
DosePro technology from our clients, particularly in the delivery of highly
viscous formulations and biologics."

The campaign highlights a study by Battelle that demonstrates the ability of
the DosePro system to effectively deliver a monoclonal antibody therapeutic,
AbbVie's Humira® (adalimumab). The in vitro study showed that DosePro can
deliver Humira without incremental risk to protein denaturation and equivalent
biological integrity as compared to delivery by pre-filled syringe.

John Turanin, Vice President and General Manager, DosePro Technology, at
Zogenix, commented, "In the three years since its launch, we have produced
more than 2 million commercial units of our first commercial DosePro product,
SUMAVEL^® DosePro^®. The introduction of a needle-free delivery option has
reinvigorated growth of injectable sumatriptan, including from patients that
were previously not interested due to needle-phobia and/or the complexity of
delivery. We are pleased to provide an enhanced needle-free option for these
patients and look forward to continue working with Battelle to introduce the
benefits of the DosePro system to potential partners in the biopharmaceutical
and government sectors."

In accordance with the extension of their co-marketing partnership, Zogenix
and Battelle will continue to market DosePro, using the "Less is More"
campaign, to Battelle's clients in strategic product planning meetings, at
medical and industry conferences, in trade publications, and through other
marketing communications. The campaign, which was launched in July 2012,
emphasizes the simplicity and benefits of the DosePro technology and its
ability to provide instantaneous, needle-free, subcutaneous drug delivery. For

About DosePro®

The DosePro system is a first-in-class, easy-to-use drug delivery system
designed for self-administration of a pre-filled, single dose of sterile
liquid drug, subcutaneously, without a needle. The platform is currently used
by Zogenix's first commercial product, SUMAVEL DosePro^®. The Company believes
that DosePro offers several benefits to patients compared to other
subcutaneous needle-based delivery methods, and that it has the potential to
become a preferred delivery option for patients and physicians. These benefits
include less anxiety or fear due to the lack of a needle, easier disposal
without the need for a sharps container, no risk of needle stick injury or
contamination, an easy-to-use three step administration process, no need to
fill the device prior to use, reliable performance, discreet use and
portability. In several clinical trials and market research studies, DosePro
has been shown to be preferred by patients over conventional needle-based
