Efficacy and safety of oral solithromycin versus oral moxifloxacin for treatment of community-acquired bacterial pneumonia: a global, double-blind, multicentre, randomised, active-controlled, non-inferiority trial (SOLITAIRE-ORAL)
Abstract
BACKGROUND: Community-acquired bacterial pneumonia (CABP) is a leading cause of morbidity and mortality, and treatment recommendations, each with specific limitations, vary globally. We aimed to compare the efficacy and safety of solithromycin, a novel macrolide, with moxifloxacin for treatment of CABP.
METHODS: We did this global, double-blind, double-dummy, randomised, active-controlled, non-inferiority trial at 114 centres in North America, Latin America, Europe, and South Africa. Patients (aged ≥18 years) with clinically and radiographically confirmed pneumonia of Pneumonia Outcomes Research Team (PORT) risk class II, III, or IV were randomly assigned (1:1), via an internet-based central block randomisation procedure (block size of four), to receive either oral solithromycin (800 mg on day 1, 400 mg on days 2-5, placebo on days 6-7) or oral moxifloxacin (400 mg on days 1-7). Randomisation was stratified by geographical region, PORT risk class (II vs III or IV), and medical history of asthma or chronic obstructive pulmonary disease. The study sponsor, investigators, staff, and patients were masked to group allocation. The primary outcome was early clinical response, defined as an improvement in at least two of four symptoms (cough, chest pain, sputum production, dyspnoea) with no worsening in any symptom at 72 h after the first dose of study drug, with a 10% non-inferiority margin. The primary analysis was by intention to treat. This trial is registered with…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 860 participants or records.
