Durata Therapeutics Announces FDA's Acceptance for Priority Review of NDA for
Dalvance(TM) (dalbavancin hydrochloride)
PDUFA Action Date of May 26, 2014
CHICAGO, Nov. 26, 2013 (GLOBE NEWSWIRE) -- Durata Therapeutics, Inc.
(Nasdaq:DRTX) today announced that the New Drug Application (NDA) for its
investigational drug, Dalvance™ (dalbavancin hydrochloride) for injection, has
been accepted for priority review by the U.S. Food and Drug Administration
(FDA) with an action date of May 26, 2014. Durata is seeking FDA approval of
Dalvance™ for the treatment of patients with acute bacterial skin and skin
structure infections (ABSSSI) caused by susceptible Gram-positive
microorganisms, including MRSA (methicillin resistant Staphylococcus aureus).
The NDA, submitted on September 26, 2013, was based on the entire data set
from Durata Therapeutics' clinical development program, including results from
two Phase 3 trials DISCOVER 1 and DISCOVER 2, as well as a previous Phase 3
study (VER001-9). Both DISCOVER 1 and DISCOVER 2 trials were conducted under a
Special Protocol Assessment (SPA) with the FDA.
"We are very pleased with the FDA's acceptance for filing of our NDA, as this
represents an important achievement in the development of Dalvance™.We
believe that Dalvance™ has the potential to make a meaningful difference in
the lives of patients with ABSSSI," said Paul R. Edick, Durata Therapeutics
Chief Executive Officer. "If approved by the FDA, Dalvance™, with its once
weekly dosing, may help facilitate an important shift in treatment from the
hospital to ambulatory settings."
For the six month period of January to June 2010, a projected 9.2 million
patients were treated in U.S. hospitals for infections of any type, and nearly
17 percent of the diagnostic category presentations were for skin and skin
structure infections (SSSIs). Of these presentations for SSSI, approximately
74 percent were disease types included in ABSSSI.^i This category of infection
increased by 176 percent from 1997 to 2009 in hospitalized patients.^ii The
majority of skin and soft tissue infections in hospitalized patients are
caused by Staphylococcus aureus, and approximately 59 percent of these
infections are estimated to be caused by MRSA in the U.S.^iii,iv Failure to
successfully treat ABSSSI may result in hospital readmissions. Under the new
health care reform laws, hospitals may incur financial penalties for
preventable hospital readmissions, including unresolved infections.
Dalvance™ (dalbavancin hydrochloride) for injection is a second generation,
semi-synthetic lipoglycopeptide, which consists of lipophilic side-chains
attached to glycopeptides. When compared to vancomycin, Dalvance™ has a longer
half-life resulting in a duration of antibacterial activity of 5-7 days per
dose.^vIf approved, Dalvance™ would be the first drug for ABSSSI requiring
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.^vi Ultimately, this may lower the overall
cost of care for these patients.
