Abstract

A continuous dosing schedule of aerosolized ribavirin has been used for respiratory syncytial virus (RSV) upper respiratory tract infection and lower respiratory tract infection (LRTI) but is associated with high cost and inconvenient administration. We conducted an adaptive randomized trial to evaluate the effectiveness of an intermittent dosing schedule of ribavirin versus that of a continuous dosing schedule of ribavirin in preventing RSV LRTIs in 50 hematopoietic stem cell transplant recipients or patients with hematologic malignancies. LRTI occurred in 3 patients (9%) receiving the intermittent schedule and in 4 (22%) receiving the continuous schedule, with a 0.889 posterior probability. Because the intermittent schedule is easy to administer and has a higher efficacy than the continuous schedule, we recommend the intermittent schedule for patients who are at risk for RSV LRTI.
