XENLETA—a flexible and
effective CABP treatment1
XENLETA was evaluated in
2 phase III CABP trials:
Trial 1 (IV to oral switch) and
Trial 2 (oral treatment only)1
XENLETA is a systemic, empiric pleuromutilin antibiotic with activity against CABP-specific Gram-positive, Gram-negative, and atypical respiratory bacteria1
XENLETA monotherapy achieved early and effective clinical response1
Results above from Trial 1 (IV with optional oral switch), which evaluated XENLETA monotherapy (n=276) for 5-10 days vs moxifloxacin ± linezolid (n=275) for 7-10 days. ECR (72-120 hours after the first dose) was defined as survival with improvement of ≥2 symptoms consistent with CABP, no worsening of any symptom, and no receipt of non-study antibacterial treatment for CABP. IACR at TOC (5-10 days after last dose) was defined as survival with improvement of signs and symptoms based on the investigator’s assessment and no receipt of non-study antibacterial treatment for CABP.1
- aIf MRSA was suspected at screening, patients randomized to moxifloxacin received adjunctive linezolid, and patients randomized to XENLETA received linezolid placebo.

Adults with acute onset of:
-
≥3 of the following (new or worsening) symptoms: dyspnea, new or
increased cough, purulent sputum production,
chest pain due to pneumonia -
≥2 of the following symptoms: fever or hypothermia,
hypotension, tachycardia, tachypnea
-
≥3 of the following (new or worsening) symptoms: dyspnea, new or
- At least 1 other clinical sign or laboratory finding of CABP
- PORT Risk Class III, IV, or V (≥25% subjects with
PORT Risk Class IV or V) - Required IV antibiotic therapy as initial treatment
- Expected (but not required) to be hospitalized
-
≤25% of randomized subjects were to have received
a single dose of a short-acting antibacterial medication
for CABP within 72 hours before randomization -
Lobar or multilobar infiltrates or diffuse opacities
on chest X-ray or chest CT scan consistent with acute
bacterial pneumonia within 48 hours before enrollment

5 days with XENLETA achieved comparable efficacy to 7 days with moxifloxacin—nearly 30% less time on treatment1,a
Results from Trial 2 (oral treatment only), which evaluated 5 days of treatment with XENLETA (n=370) vs 7 days of treatment with moxifloxacin (n=368). ECR (72-120 hours after the first dose) was defined as survival with improvement of ≥2 symptoms consistent with CABP, no worsening of any symptom, and no receipt of non-study antibacterial treatment for CABP. IACR at TOC (5-10 days after last dose) was defined as survival with improvement of signs and symptoms based on the investigator’s assessment and no receipt of non-study antibacterial treatment for CABP.1

Proven microbiologic activity and response in CABP1
XENLETA targets and acts against the pathogens that commonly cause CABP, including S. pneumoniae and others.1
Clinical response rates at TOC by baseline pathogen (Trial 1 and Trial 2)1,a
XENLETA has shown in vitro activity against
methicillin-resistant Staphylococcus aureus
(MRSA) isolates. However, the clinical
significance of this is unknown.1
