NEW HAVEN, Conn, Aug. 11, 2014 (GLOBE NEWSWIRE) -- Melinta Therapeutics today announced top-line results of a Phase 1 clinical study that demonstrated that the administration of single doses of 450 mg oral and 300 mg intravenous (I.V.) formulations of delafloxacin provide similar blood exposure. Delafloxacin is an investigational fluoroquinolone under development for acute bacterial skin and skin structure infections and uncomplicated gonorrhea.

In this study of 56 healthy adults, the oral formulation provided total comparable exposure (area under the curve-AUC) compared to I.V. administration, meeting pre-defined criteria. Peak blood levels were lower with the oral compared with I.V. dosing. Since antimicrobial activity for delafloxacin is correlated with AUC, these data support "step-down" from intravenous to oral dosing. Single doses in both groups were well tolerated.

Complete results from these studies will be presented at the 54th annual Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC), an American Society for Microbiology meeting. ICAAC is being held September 5-9, 2014 at the Washington, DC Convention Center.
