~ Application Seeks to Expand Label to Include an Indication and Phase III Data for the Treatment of Adult Patients with Community-Acquired Bacterial Pneumonia (CABP) ~

~ PDUFA Date Set for October 24, 2019 ~

MORRISTOWN, N.J., June 19, 2019 (GLOBE NEWSWIRE) -- Melinta Therapeutics, Inc. (NASDAQ: MLNT), a commercial-stage company focused on the development and commercialization of novel antibiotics to treat serious bacterial infections, today announced the U.S. Food and Drug Administration (FDA) has accepted a supplemental New Drug Application (sNDA) for BAXDELA® (delafloxacin) for priority review. The sNDA filing seeks to expand the current indication for BAXDELA to include adult patients with community-acquired bacterial pneumonia (CABP).

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, or CABP, remains a challenge for healthcare professionals and has led to a need for new treatment options,” said Sue Cammarata, M.D., 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.

BAXDELA was 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.

About BAXDELA

BAXDELA® (delafloxacin) tablets and intravenous injection are approved by the U.S. Food and Drug Administration (FDA) for the treatment of acute bacterial skin and skin structure infections (ABSSSI). BAXDELA was approved by the FDA in 2017 based on its efficacy against both gram-positive and gram-negative pathogens, including MRSA. It was given priority review by the FDA due to its designation as a Qualified Infectious Disease Product (QIDP) under the Generating Antibiotic Incentives Now (GAIN) Act of 2012. The QIDP designation qualifies BAXDELA for certain incentives related to the development of new antibiotics, including a five-year extension of any non-patent exclusivity period awarded to the drug.

INDICATION & USAGE

BAXDELA is indicated in adults for the treatment of acute bacterial skin and skin structure infections (ABSSSI) caused by susceptible isolates of the following:
Gram-positive organisms: Staphylococcus aureus (including methicillin-resistant [MRSA] and methicillin-susceptible [MSSA] isolates), Staphylococcus haemolyticus, Staphylococcus lugdunensis, Streptococcus agalactiae, Streptococcus anginosus group (including Streptococcus anginosus, Streptococcus intermedius, and Streptococcus constellatus), Streptococcus pyogenes, and Enterococcus faecalis;
Gram-negative organisms: Escherichia coli, Enterobacter cloacae, Klebsiella pneumoniae, and Pseudomonas aeruginosa.

IMPORTANT SAFETY INFORMATION:

WARNING: SERIOUS ADVERSE REACTIONS INCLUDING TENDINITIS, TENDON RUPTURE, PERIPHERAL NEUROPATHY, CENTRAL NERVOUS SYSTEM EFFECTS, and EXACERBATION OF MYASTHENIA GRAVIS

Fluoroquinolones have been associated with disabling and potentially irreversible serious adverse reactions that have occurred together, including:

  • Tendinitis and tendon rupture
  • Peripheral neuropathy
  • Central nervous system effects

Discontinue BAXDELA immediately and avoid the use of fluoroquinolones, including BAXDELA, in patients who experience any of these serious adverse reactions.

Fluoroquinolones may exacerbate muscle weakness in patients with myasthenia gravis. Avoid BAXDELA in patients with known history of myasthenia gravis.

Contraindications
BAXDELA is contraindicated in patients with known hypersensitivity to BAXDELA or other fluoroquinolones.

Warnings and Precautions
Fluoroquinolones have been associated with disabling and potentially irreversible serious adverse reactions. Avoid use in patients who have experienced any of the following serious adverse reactions. If these reactions occur in patients receiving BAXDELA, discontinue BAXDELA immediately and institute appropriate treatment:

  • Tendinitis, tendon rupture, with increased risk in elderly, patients taking corticosteroids and in patients with organ transplants
  • Peripheral neuropathy, such as pain, burning, tingling, numbness, and/or weakness or other alterations of sensation in touch and/or motor strength
  • Psychiatric adverse reactions, such as toxic psychosis; hallucinations, or paranoia; depression, or suicidal thoughts or acts; delirium, disorientation, confusion, or disturbances in attention; anxiety, agitation, or nervousness; insomnia or nightmares; memory impairment
  • Central nervous system adverse reactions such as seizures, increased intracranial pressure, dizziness, and tremors
  • Exacerbation of myasthenia gravis, including death and requirement for ventilator

Hypersensitivity reactions have been reported in patients receiving fluoroquinolones, including BAXDELA. Reactions can be serious and occasionally fatal (anaphylactic). Discontinue BAXDELA at the first sign of hypersensitivity.

Clostridium difficile-associated diarrhea has been reported with nearly all systemic antibacterial agents, including BAXDELA, with severity ranging from mild diarrhea to fatal colitis. Evaluate if diarrhea occurs.

Fluoroquinolones have been associated with an increased risk of aortic aneurysm and dissection, especially in elderly patients. In patients with a known aortic aneurysm or patients who are at greater risk for aortic aneurysms, reserve BAXDELA for use only when there are no alternative antibacterial treatments available.

Prescribing BAXDELA in the absence of a proven or strongly suspected bacterial infection is unlikely to provide benefit to the patient and increases the risk of the development of drugresistant bacteria.

Fluoroquinolones have been associated with disturbances of blood glucose, including symptomatic hyperglycemia and hypoglycemia. Severe cases of hypoglycemia resulting in coma or death have been reported with other fluoroquinolones. Monitor blood glucose carefully in diabetic patients receiving oral hypoglycemic agents or insulin. Discontinue BAXDELA and initiate appropriate therapy immediately if a hypoglycemic reaction occurs.

Adverse Reactions
The most common adverse reactions in patients treated with BAXDELA were nausea (8%), diarrhea (8%), headache (3%), transaminase elevations (3%), and vomiting (2%).

Use in Specific Populations
In patients with severe renal impairment (eGFR of 15-29 mL/min/1.73 m2), the dosage of BAXDELA should be decreased to 200 mg IV every 12 hours or 450 mg orally every 12 hours. BAXDELA is not recommended in patients with End Stage Renal Disease [ESRD] (eGFR of <15 mL/min/1.73 m2, including hemodialysis) due to insufficient information to provide dosing recommendations.
