Study design (if review, criteria of inclusion for studies)
RCT
Participants
520 patients, aged > or = 6 years, with moderate-to-severe CF
Interventions
Patients received tobramycin solution for inhalation (TSI) or placebo, which was administered in alternating cycles of 28-days-on and 28- days-off therapy, plus their usual CF care for 6 months with open-label follow-up extended to 2 years
Outcome measures
long-term safety and effectiveness
Main results
Most AEs declined in frequency with increasing TSI exposure. Patients receiving TSI spent 25 to 33% fewer days in the hospital. Following the initiation of TSI treatment, patients experienced significant increases in FEV(1). FEV(1) values were maintained above baseline for the duration of the study series. Antibiotic susceptibility of the bacterial isolates did not predict clinical response.
Authors' conclusions
TSI was safe, well-tolerated, and effective for long-term treatment (96 weeks) of P aeruginosa colonization and infection in CF patients.
