TRAROTreatment of Rotator Cuff Syndrome and Bursitis: A Double Blind, Controlled Trial to Assess the Efficacy and Safety of Traumeel® S Injection Versus Corticosteroid Injections and Versus Placebo

Duration of the study were 16 weeks. Duration of Treatments were 15 days, applying one injection of 2 ml od study medication at days 1, 8, and 15. There was a follow up visit at day 22 (Primary endpoint), a telephone visit at week 9 and a final visit at week 15. Standard descriptive summary statistics were calculated for continuous variables (i.e. arithmetic mean, standard deviation, minimum value, median, maximum value, number of non-missing values). All statistical analyses in this study were of exploratory nature. The summaries of the efficacy parameters, the statistical analyses of the primary efficacy variable, and the statistical analyses of the secondary efficacy variables were performed on the PP Set. These summaries and analyses were supported by corresponding summaries and exploratory statistical analyses performed on the Full Analysis Set. Missing values for all efficacy parameters were imputed by the last observation carried forward (LOCF) approach. The Modified Per-Protocol (MPP) Set excluded from the PP Set also all patients having taken unallowed concomitant medication after Visit 5 and was used as a secondary population for the analysis of efficacy. All statistical tests were two-sided with a significance level of (alpha) = 0.05, unless specified otherwise. The primary efficacy variable was the change from baseline in VAS for abduction rotation pain at Visit 5 (Day 22) (Traumeel® S injections versus corticoid injections) for active external rotation. A one-sided test of non-inferiority of Traumeel® S with respect to dexamethasone at level 0.025 was computed using an analysis of covariance (ANCOVA) model with treatment group as qualitative factor and the baseline value of the abduction rotation pain VAS for active external rotation as a covariate. The test decision was based on a one-sided 97.5% confidence interval for the corresponding treatment difference. The non-inferiority margin was set to 13 mm on a 0 - 100 mm VAS scale.
