The US FDA has accepted a supplemental New Drug Application (sNDA) for an expanded indication of Baxdela (delafloxacin) to treat adult patients with community-acquired bacterial pneumonia (CAP), according to Melinta Therapeutics Inc.

Baxdela tablets and intravenous injection were approved by the FDA in 2017 for the treatment of adult patients with acute bacterial skin and skin structure infections (ABSSSI) caused by designated susceptible bacteria.

The FDA granted priority review status based on the previous Qualified Infectious Disease Product (QIDP) designation, which provides certain incentives for the development of antibacterial and antifungal treatments for serious or life-threatening infections. Through this process, the FDA has assigned a Prescription Drug User Fee Act (PDUFA) action date (proposed review deadline) of October 24, 2019.

“Due to the rise of antibiotic resistance and an aging population, community-acquired bacterial pneumonia remains a challenge for healthcare professionals and has led to a need for new treatment options,” said Sue Cammarata, MD, chief medical officer of Melinta. “Baxdela’s potency and activity against the most common bacterial pathogens seen in CABP indicate it could play a significant role in the treatment of this life-threatening illness, if approved. We look forward to working with the FDA to help evaluate bringing this potential option to people with CABP as soon as possible.”

The sNDA application is based on positive results from a Phase III, randomized, double-blind, study that compared the efficacy and safety of Baxdela to moxifloxacin for the treatment of CABP. The study results showed that Baxdela had comparable efficacy to moxifloxacin for early clinical response and clinical outcome at test of cure.

Additionally, Baxdela was generally safe and well-tolerated. Detailed efficacy and safety results from this study will be submitted for presentation at an upcoming medical conference.
