Mechanism of action

Placebo is an inert substance used as a control in clinical trials to establish baseline efficacy and safety of an active drug (in this case, omalizumab). Any observed effects are attributable to the placebo effect—psychological and physiological responses to the expectation of treatment rather than the substance itself.
