Mechanism of action

Placebo is an inert substance used as a control in clinical trials to establish the efficacy of an active drug by comparison. It allows researchers to distinguish between the therapeutic effects of the actual drug and effects attributable to patient expectation, natural disease progression, or other non-pharmacological factors. In this context, it serves as the control arm in a Phase 3 trial for Niraparib, a PARP inhibitor.
