Study of Two Doses of Crizanlizumab Versus Placebo in Adolescent and Adult Sickle Cell Disease Patients — STAND  

Sickle Cell Disease (SCD) Clinical Trial

Official title: A Phase III, Multicenter, Randomized, Double-blind Study to Assess Efficacy and Safety of Two Doses of Crizanlizumab Versus Placebo, With or Without Hydroxyurea/ Hydroxycarbamide Therapy, in Adolescent and Adult Sickle Cell Disease Patients With Vaso-Occlusive Crises (STAND)

Status Active, not recruiting

Clinical Trial Summary

The purpose of this study is to compare the efficacy and safety of 2 doses of crizanlizumab (5.0 mg/kg and 7.5 mg/kg) versus placebo in adolescent and adult sickle cell disease (SCD) patients with history of vaso-occlusive crisis (VOC) leading to healthcare visit.

Clinical Trial Description

Study CSEG101A2301 (STAND) is an ongoing Phase III, multicenter, randomized, double-blind study to assess efficacy and safety of two doses of crizanlizumab (5 mg/kg and 7.5 mg/kg) versus placebo, with or without hydroxyurea/ hydroxycarbamide therapy (HU/HC), in adolescent and adult patients with SCD and history of VOC leading to healthcare visit.

This is a multicenter clinical trial comparing 2 doses of crizanlizumab (5 mg/kg and 7.5 mg/kg) versus placebo in addition to standard of care participants might be taking at the time of study start, in adolescent and adult participants with confirmed diagnosis of sickle cell disease (SCD) and history of vaso-occlusive crisis (VOC) leading to a healthcare visit.

240 participants (including 48 adolescents) were planned to be randomized in a 1:1:1 ratio to either 5 mg/kg, 7.5 mg/kg of crizanlizumab or placebo. Randomized participants were stratified by concomitant HU/HC usage (yes/no) and baseline rate of VOCs leading to a healthcare visit in 12 months prior to screening visit (2-4 vs. ≥ 5 VOCs) at the time of enrollment. In November 2020, a capping of 90 adult participants per strata was implemented to ensure adequate opportunity for enrollment into each of the 4 strata. ;
