A Study of Efficacy and Safety of Ianalumab Versus Placebo in Addition to Eltrombopag in Primary Immune Thrombocytopenia Patients Who Failed Steroids

This is a multicenter, randomized, double-blinded phase 3 study to assess efficacy and safety of two different doses of ianalumab versus placebo in addition to eltrombopag in adults with primary ITP (platelet count <30 G/L) who failed previous first-line treatment with corticosteroids. After completion of the screening period, the participants will enter the randomized treatment period (ianalumab/placebo with eltrombopag) followed by the eltrombopag tapering period. Afterwards, all participants will enter the follow-up period to be monitored for efficacy and safety or safety only depending on how the participants responded to the study treatment.
