Mechanism of action

Placebo formulations are inert preparations designed to match the appearance, taste, and administration route of an active drug to enable blinded clinical trial comparisons. In this Phase 3 trial context, the matched placebo allows assessment of the true efficacy of HB/APAP by controlling for expectancy effects and natural disease progression. The matching ensures that neither patients nor investigators can distinguish the placebo from active treatment based on sensory cues.
