Estudo de Ianalumab Versus Placebo em adição aos corticosteróides de primeira linha na Trombocitopenia Imune Primária (PTI) (VAYHIT1)

10 de novembro de 2026 atualizado por: Novartis Pharmaceuticals

Um estudo de fase III, randomizado, duplo-cego de Ianalumabe (VAY736) versus placebo em adição a corticosteróides de primeira linha na trombocitopenia imune primária (VAYHIT1)

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.

Descrição detalhada

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.
