Trial Outcomes & Findings for A Study of Tobramycin Inhalation Powder From a Modified Manufacturing Process Versus Placebo (NCT NCT00918957)

NCT ID: NCT00918957

Last Updated: 2012-10-03

Results Overview

Relative change in percentage predicted FEV1 in the Intent-to-treat (ITT), modified ITT (mITT) and Observed cases in the ITT populations were calculated from an adjusted analysis ANOVA model. ITT Patients with missing or unacceptable Day 29 spirometry measurements had their primary endpoint data imputed with zero. BSL = Baseline, defined as the latest measurement prior to the first dosing of study medication \- Relative change = 100 \* (value - baseline) / baseline There were 3 patients who had no screening nor baseline values (due to inadequate spirometry) and so were excluded from all change from baseline analyses.

Participant Flow

Although 32 patients were randomized to the TIP group and 30 to the Placebo group, the ITT population included 2 patients allocated to the TIP group but received placebo due to Investigator error during the drug dispensation process. The safety population contained 30 patients who were treated with TIP and 32 patients who were treated with placebo.

Timeframe: Baseline, Day 29

Population: ITT: All randomized patients (pts) received at least one dose of study drug. Missing or unacceptable Day 29 spirometry test -change from baseline FEV1 % predicted imputed using last available post-baseline value or 0. mITT: Pts with unacceptable FEV1 measurements excluded. Observed cases: Pts with missing or unacceptable FEV1 measurements excluded.

Absolute change in percentage predicted FEV1 in the Intent-to-treat (ITT), modified ITT (mITT) and Observed cases in the ITT populations were calculated from an adjusted analysis ANOVA model. In the adjusted analysis model: response = treatment + screening FEV1 % predicted (\<50 and \>=50) + age (\<13 and \>=13) + error. Significance for the FEV1 % predicted is reached for p-values \<= 0.05. There were 3 patients who had no screening nor baseline values (due to inadequate spirometry) and so were excluded from all change from baseline analyses.

Maximum MIC values from all biotypes were used. Absolute values and changes in tobramycin MIC for P. aeruginosa from baseline are summarized by biotype. Overall, a high variability of MIC was observed within each treatment group. For the maximum of all biotypes, large differences in mean changes from baseline at Day 29 were observed between the TIP group and the placebo group.

SECONDARY outcome

Timeframe: First administration of study drug, study completion

Population: Safety population: All randomized patients who received at least one dose of study drug.In all safety analyses patients were analyzed according to the treatment received

Adverse Events (AEs) (on and off treatment) regardless of study relationship by primary system organ and treatment group. Primary system organ classes are sorted in descending order of frequency in the TIP treatment group. A patient with more than one AE within a primary system organ class is counted only once for that class.

Timeframe: Time of consent, 4 weeks after study completion

Population: Safety population: All randomized patients who received at least one dose of study drug. In all safety analyses patients were analyzed according to the treatment received.

Serious Adverse Events (on and off treatment) by preferred term and treatment group. Preferred terms are sorted in descending order of frequency in the TIP treatment group. A patient with multiple occurrences of the same preferred term is counted only once in the preferred term.

Population: Safety population: All randomized patients who received at least one dose of study drug. In all safety analyses patients were analyzed according to the treatment received. This measures the concentration of active substance in the body at different time-point to evaluate there is abnormal accumulation of active substance. Not for Placebo Patients.

Descriptive statistics of serum and sputum concentrations per scheduled sampling time. Detectable concentration values at pre-dose on Day 1 were excluded from the analysis.
