Zogenix Announces Initiatives to Reach Key Business Milestones

Cost Control Initiatives Extend Cash Runway

SAN DIEGO, June 5, 2013 (GLOBE NEWSWIRE) -- Zogenix, Inc. (Nasdaq:ZGNX), a
pharmaceutical company commercializing and developing products for the
treatment of central nervous system disorders and pain, announced today
initiatives to extend its cash runway to reach key business milestones that
may occur over the remainder of the year. These milestones include the
Company's efforts to gain U.S. Food and Drug Administration (FDA) approval for
its New Drug Application (NDA) for Zohydro ER^TM (hydrocodone bitartrate
extended release capsules) for chronic pain, to secure a development partner
for Relday^TM, a once-monthly injectable formulation of risperidone for
schizophrenia, and to out-license the Company's proprietary DosePro
needle-free delivery technology. The initiatives underway are expected to
extend the Company's cash runway beyond the potential achievement of one or
more of these milestones during the second half of 2013.

The Company's initiatives include:

  *A reduction in the Company's workforce of 148 by a total of 55 full-time
    equivalent employees (approximately 37%) across all functional areas of
    the Company.
  *Maintaining the Company's core commercial capabilities and ability to
    support the potential launch of Zohydro ER three to four months after
    potential approval by retaining 93 full-time equivalent employees,
    including 57 in sales and marketing. The expected timeline for FDA action
    on the Zohydro ER NDA is unchanged and remains sometime this summer.
  *Cost control initiatives to further reduce operating expenses and capital
  *Increase focus on reaching SUMAVEL DosePro brand-level profitability, and
    to leverage the Zogenix sale force presence in neurology. The Company is
    making encouraging progress towards securing a second product to
    co-promote with a goal of beginning sometime this summer.

Roger L. Hawley, chief executive officer of Zogenix, stated, "We have not
received any new updates from the FDA on the timing of their decision
regarding the Zohydro ER NDA and remain confident in the Zohydro ER program.
In addition, Zogenix has other upcoming value creating milestones that could
occur in the second half of the year. We are implementing these initiatives to
ensure we are in a position to benefit from these potential milestones while
also continuing to support our existing commercial business and partners. Our
approach includes a balance of expense reduction, a reduction in workforce,
cost controls, and progress in business development efforts.

Mr. Hawley concluded, "The reduction to our workforce was an extremely
difficult decision for our management team and our Board. I have great respect
for all of our employees and thank them for the contribution they make every
day for the patients we serve. I would like to thank all of our departing
employees for their hard work, enthusiasm and dedication to our corporate
mission. Planning for our future, we have preserved our core commercial
capabilities while reducing the size of our team in light of the unfortunate
FDA delay on Zohydro ER."

Zogenix expects to record most of the expense related to the reduction in
force with a one-time charge of approximately $1.0 million in the second
quarter 2013. To date, the Company has not raised any capital through its $25
million At The Market ("ATM") facility.
