CABP Overview

A Broad Coverage Oral Monotherapy for CABP*1

* BAXDELA (delafloxacin) is indicated in adults for the treatment of community-acquired bacterial pneumonia (CABP) caused by the following susceptible microorganisms:

  • Gram-positive organisms
    • Staphylococcus aureus (methicillin-susceptible only)
    • Streptococcus pneumoniae
  • Gram-negative organisms
    • Escherichia coli
    • Klebsiella pneumoniae
    • Haemophilus influenzae
    • Haemophilus parainfluenzae
    • Pseudomonas aeruginosa
  • Atypical organisms
    • Chlamydia pneumoniae
    • Legionella pneumophila
    • Mycoplasma pneumoniae

Safety Profile Demonstrated in Clinical Studies

  • No evidence of QT prolongation was observed in patients taking BAXDELA 300 or 900 mg IV in a definitive QT study vs oral moxifloxacin 400 mg or placebo
  • No clinically significant phototoxic potential was observed in BAXDELA 200 or 400 mg/day oral in a photosafety study vs lomefloxacin as the active comparator
  • BAXDELA showed minimal potential for drug-drug interactions during development
    • Does not inhibit cytochrome P450 at clinically relevant doses
    • Oral BAXDELA should be taken 2 hours before or 6 hours after antacids or multivitamins containing iron or zinc.
Most Common Adverse Reactions
Occurring in ≥2% of Patients (from Phase 3 CABP trial)

Simple Oral Monotherapy

  • No oral dosage adjustment required due to:
  • 450-mg tablet BID for 5 to 10 days
  • No food effect

BAXDELA is not recommended in patients with End Stage Renal Disease (ESRD) (eGFR >15 mL/min/1.73 m2), including patients on hemodialysis, due to insufficient information for dosing recommendations.

Demonstrated Efficacy Across Range of Patients with CABP*†‡1-3

BAXDELA was studied in a randomized, multicenter, multinational, double-blind, double-dummy, non-inferiority trial comparing BAXDELA 300 mg IV BID with an option to switch to BAXDELA tablet 450 mg PO BID to moxifloxacin 400 mg IV QD with an option to switch to moxifloxacin 400 mg PO QD.

BAXDELA Demonstrated Efficacy in Phase 3 trial vs. moxifloxacin

Pre-Specified Analysis in COPD/Asthma Subpopulation

* BAXDELA is indicated in adults for the treatment of community-acquired bacterial pneumonia (CABP) caused by the following susceptible microorganisms: Streptococcus pneumoniae, Staphylococcus aureus (methicillin-susceptible [MSSA] isolates only), Klebsiella pneumoniae, Escherichia coli, Pseudomonas aeruginosa, Haemophilus influenzae, Haemophilus parainfluenzae, Chlamydia pneumoniae, Legionella pneumophila, and Mycoplasma pneumoniae.
To reduce the development of drug-resistant bacteria and maintain the effectiveness of BAXDELA and other antibacterial drugs, BAXDELA should be used only to treat infections that are proven or strongly suspected to be caused by susceptible bacteria.

† Evaluated in the intent to treat (ITT) population = all randomized patients.

‡ BAXDELA clinical trials demonstrated consistent efficacy across gender, age, weight, prior antibiotic use, baseline bacteremia, and PORT score in the CABP clinical trial.

§ Early Clinical Response (ECR) at 72-120 hours after the first dose, was defined as survival with improvement in at least two of four symptoms (cough, sputum production, chest pain, dyspnea) from baseline without deterioration in any of these symptoms, and without use of additional antimicrobial therapy for treatment of the current CABP infection due to lack of efficacy.

‖ Clinical response was also assessed by the investigator at the test of cure (TOC) visit and defined as survival with resolution or near resolution of the symptoms of CABP present at study entry, and no use of additional antimicrobial therapy for the current CABP infection, and no new symptoms associated with the current CABP infection.
