Durata Therapeutics Submits Marketing Authorization Application for
Dalbavancin

CHICAGO, Dec. 3, 2013 (GLOBE NEWSWIRE) -- Durata Therapeutics, Inc.
(Nasdaq:DRTX) today announced that it has submitted a Marketing Authorization
Application (MAA) to the European Medicines Agency (EMA) for dalbavancin
seeking approval for the marketing and sale of dalbavancin for the treatment
of patients with complicated skin and soft tissue infections (cSSTI) caused by
susceptible Gram-positive microorganisms, including Staphylococcus aureus
(including methicillin-resistant strains) and Streptococcus pyogenes, as well
as certain other streptococcal species. Following the standard EMA review
cycle timing, the Company anticipates a decision in 1H2015.

"The EMA marketing authorization application submission is an important
milestone in the development of dalbavancin. If approved, dalbavancin will be
the first drug for cSSTI with unique once-weekly dosing given in a short,
30-minute IV infusion time, which may help reduce the overall burden of care
without sacrificing patient outcome," said Paul R. Edick, Durata Therapeutics'
Chief Executive Officer. "In the US, there is a focus on optimizing the
location of treatment and clinical outcomes, as well as controlling the cost
of IV antibiotic delivery. We believe a similar shift will take place in
Europe in the next few years.With a long-acting, once weekly IV antibiotic
treatment option, there may be a dramatic potential savings in terms of total
cost of care when compared to daily IV antibiotic delivery."

The submission included results from the two Phase 3 trials, DISCOVER 1 and
DISCOVER 2, as well as a previous Phase 3 study (VER001-9). In the DISCOVER
trials, cSSTI was defined as cellulitis, wound infection, or major cutaneous
abscess with an associated area of surface erythema measuring at least 75 cm^2
accompanied by at least two other local signs of infection and at least one of
the following systemic signs of infection: fever, leukocytosis, or increased
immature neutrophils.

The EMA submission follows the US Food and Drug Administration's (FDA)
acceptance for priority review of the New Drug Application (NDA) for Dalvance™
(dalbavancin hydrochloride) with an action date of May 26, 2014, which was
announced on November 26, 2013.

ABOUT DALBAVANCIN

Dalbavancin is a second generation, semi-synthetic lipoglycopeptide, which
consists of lipophilic side-chains attached to glycopeptides. When compared to
vancomycin, dalbavancin has a longer half-life resulting in a duration of
antibacterial activity of 5-7 days per dose.^iIf approved by EMA,
dalbavancin would be the first drug for cSSTI requiring only two once-weekly
30-minute intravenous doses (1000 mg on Day 1 and 500 mg on Day 8). This may
shorten the length of stay for patients who are hospitalized and, for
appropriate patients, enable therapy in an outpatient setting eliminating the
hospital admission altogether.^ii Ultimately, this may lower the overall cost
of care for these patients.
