Outcome Measures
Primary Outcomes (1)
Number of Participants With Adverse Events
Safety and tolerability were assessed based on changes in: frequency of adverse events (AEs), frequency of serious adverse events (SAEs), and discontinuation due to AEs. No statistical comparison between the groups was conducted as all participants received the same study product.
18 months
Secondary Outcomes (5)
Change in Score on the BAD Scale -- Comparison of Treatment Groups Over Each Study
Baseline and Month 18 of each study
Change in Score on the BAD Scale -- Comparison of Placebo-DFP Patients Across Studies
