HB-adMSCs vs Placebo for the Treatment of Juvenile Idiopathic Arthritis
brief summary
Methodology: Randomized, double-blind, AB/BA cross-over study with a washout period of 12 weeks. Treatment Duration: 8 weeks per group General Objectives: To assess the efficacy and safety of multiple intravenous infusions of allogeneic HB-adMSCs by improving signs and symptoms of juvenile idiopathic arthritis in this subject population. Number of Subjects: 66 (6 subjects in Cohort 1 and 60 subjects in Cohort 2) Indication: Juvenile Idiopathic Arthritis
detailed description
Primary Objectives:
* To assess the safety of intravenous infusions of allogeneic HB-adMSCs vs placebo in patients with oligoarticular or polyarticular juvenile idiopathic arthritis as determined by the incidence of adverse events or serious adverse events. (Time Frame: Week 0 to Week 72). * To investigate the efficacy of intravenous infusions of allogeneic HB-adMSCs vs placebo in patients with oligoarticular or polyarticular juvenile idiopathic arthritis as determined by improvements in ACR Pedi 30 scores. (Time Frame: Week 0 to Week 52 for Group AB and Week 0 to Week 72 for Group BA).
Secondary Objectives
* To evaluate the efficacy of intravenous infusions of allogeneic HB-adMSCs vs placebo in patients with oligoarticular or polyarticular juvenile idiopathic arthritis as determined by improvements in ACR Pedi 50 scores. (Time Frame: Week 0 to Week 52 for Group AB and Week 0 to Week 72 for Group BA). * To evaluate the efficacy of intravenous infusions of allogeneic HB-adMSCs vs placebo in patients with oligoarticular or polyarticular juvenile idiopathic arthritis as determined by improvements in ACR Pedi 70 scores. (Time Frame: Week 0 to Week 52 for Group AB and Week 0 to Week 72 for Group BA). * To evaluate the efficacy of intravenous infusions of allogeneic HB-adMSCs vs placebo in patients with oligoarticular or polyarticular juvenile idiopathic arthritis as determined by improvements in CRP values. (Time Frame: Week 0 to Week 52 for Group AB and Week 0 to Week 72 for Group BA). * To evaluate the efficacy of intravenous infusions of allogeneic HB-adMSCs vs placebo in patients with oligoarticular or polyarticular juvenile idiopathic arthritis as determined by improvements in ESR values. (Time Frame: Week 0 to Week 52 for Group AB and Week 0 to Week 72 for Group BA). * To evaluate the efficacy of intravenous infusions of allogeneic HB-adMSCs vs placebo in patients with oligoarticular or polyarticular juvenile idiopathic arthritis as determined by improvements in Peds QL scores. (Time Frame: Week 0 to Week 52 for Group AB and Week 0 to Week 72 for Group BA).
