원발성 면역 혈소판 감소증(VAYHIT1)에서 1차 코르티코스테로이드와 Ianalumab(VAY736) 대 위약의 III상, 무작위 이중 맹검 연구

The purpose of this study is to evaluate the effect of two different doses of ianalumab versus placebo in addition to first-line corticosteroids in increasing the rate of stable response off treatment at 12 months (SROT-12) in adult participants with primary ITP.

상세 설명

This is a multi-center, randomized, double-blind Phase 3 study to assess the efficacy and safety of two different doses of ianalumab compared to placebo in adults with primary ITP (platelets count <30 G/L) who require first-line standard-of-care corticosteroids.

After completion of the screening period, the participants will enter the randomized treatment period (ianalumab/placebo with standard of care corticosteroids).

After the treatment period, all participants will enter the follow-up period to be monitored for efficacy and safety or safety only depending on how they respond to the study treatment.

The efficacy and safety follow-up period will last until treatment failure or up to 39 months after randomization of the last patient, whichever occurs first. Safety follow-up period will be performed for at least 20 weeks and up to 2 years after the last ianalumab/placebo dose.

The primary endpoint was updated in May 2026 to stable response off treatment at 12 months (SROT-12). The previous primary endpoint, time to treatment failure (TTF), remains in the study as a key secondary objective.
