Trial design

Randomised, placebo (matching placebo for piclidenoson) given orally every 12 hours; segment 1: piclidenoson 3 mg every 12 hours for 16 weeks vs matching placebo every 12 hours for 16 weeks. segment 2: medication taken orally bid for up to 52 weeks with placebo-to-active switch at week 17 for subjects initially on placebo, and rerandomization (1:1, blinded) in period c for responders to continue piclidenoson or switch to placebo (withdrawal).-controlled, crossover, adaptive Phase III trial in Greece, Poland, Bulgaria.

Randomised
Yes
Comparator
Placebo (matching placebo for piclidenoson) given orally every 12 hours; Segment 1: piclidenoson 3 mg every 12 hours for 16 weeks vs matching placebo every 12 hours for 16 weeks. Segment 2: medication taken orally BID for up to 52 weeks with placebo-to-active switch at Week 17 for subjects initially on placebo, and rerandomization (1:1, blinded) in Period C for responders to continue piclidenoson or switch to placebo (withdrawal).
Adaptive
True, an interim analysis for futility will be performed after required number of subjects complete Segment 1 (enrollment paused for futility analysis). Segment 2 enrollment proceeds only if futility is not declared. Segment 2 also includes rerandomisation/withdrawal rules (responders rerandomised to continue or withdraw treatment) and predefined retreatment rules based on loss of response.
Crossover
Yes
