Melinta Therapeutics' Phase 3 Study of I.V. and Oral Delafloxacin has Begun Enrolling Patients with Acute Bacterial Skin and Skin Structure Infections

NEW HAVEN, Conn, May 5, 2014 (GLOBE NEWSWIRE) -- Melinta Therapeutics today announced that patient enrollment has commenced in a Phase 3 trial of oral and intravenous (I.V.) delafloxacin, a novel fluoroquinolone, in adults with acute bacterial skin and skin structure infections (ABSSSI). This study compares the efficacy and safety of both formulations of delafloxacin to a control regimen of I.V. vancomycin plus aztreonam. Delafloxacin was designated a Qualified Infectious Disease Product (QIDP) by the FDA for the treatment of ABSSSI, a classification that provides an additional five years of market exclusivity (for a total of ten years) following approval.

Dr. Eugene Sun, executive vice president, research and development of Melinta, commented, "ABSSSI is a broad term describing a variety of challenging skin infections, often involving methicillin-resistant Staphylococcus aureus (MRSA), which are best addressed with multiple treatment options. To address this need, Melinta is developing oral and I.V. formulations of delafloxacin to provide flexibility in the management of these patients."

Results from this Phase 3 study (ML-3341-303; NCT01984684) and those from a second, ongoing Phase 3 study of I.V. delafloxacin (ML-3341-302;

NCT01811732) are expected to support the filing of regulatory applications with the U.S. Food and Drug Administration (FDA) and foreign regulators.

Mary Szela, Melinta's chief executive officer concluded, "We believe that the development of an oral formulation of delafloxacin in addition to an I.V. formulation will be an important factor for hospitals and physicians when evaluating treatment options for their patients."

About the Study

The ML-3341-303 study is a double-blind and double-dummy design in which approximately 660 patients with ABSSSI are expected to be enrolled. Patients will be randomized to receive either delafloxacin or vancomycin plus aztreonam. Patients in the delafloxacin arm will receive I.V. delafloxacin twice daily for three days, after which they will switch to oral delafloxacin twice daily. Patients in the control arm will receive I.V. vancomycin plus aztreonam every 12 hours. All patients will receive a minimum of 5 days of dosing, with a maximum of 14 days of treatment at the investigators' discretion.
