Safety and efficacy of omadacycline by body mass index in patients with community-acquired bacterial pneumonia: Subanalysis from a randomized controlled trial
Abstract
OBJECTIVES
To examine the safety and efficacy of omadacycline by body mass index (BMI) in adults with community-acquired bacterial pneumonia (CABP) from a Phase III trial.
METHODS
Patients hospitalized for suspected CABP were randomized 1:1 to receive intravenous omadacycline or moxifloxacin, with an optional transition to oral, for a total of 7-14 days. Early clinical response (ECR) was assessed 72-120 h after receipt of the first dose, and clinical success was assessed 5-10 days after the last dose (post-treatment evaluation [PTE]). ECR was defined as improvement in at least two CABP symptoms with no worsening of other symptoms or use of rescue antibacterial treatment; success at PTE was defined as resolution of signs and symptoms to the extent that further antibacterial therapy was unnecessary. Safety evaluations included treatment-emergent adverse events and laboratory measures. Between-treatment comparisons were made by World Health Organization BMI categories and by diabetes history.
RESULTS
Distribution of patients in the normal weight, overweight, and obese subgroups was fairly even. Clinical success for omadacycline-treated patients at ECR were similar across ascending BMI groups (OMC: 82.9%, 80.5%, 76.9%; MOX: 88.6%, 80.7%, 76.9%). Outcomes by diabetes status were generally similar in omadacycline- and moxifloxacin-treated patients. Patients who had clinical success or clinical stability at ECR generally showed continued clinical success at PTE. Safety profiles for…
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.
