"hb-admscs for the treatment of patients with multiple sclerosis"

Conditions: Relapsing Remitting Multiple Sclerosis (RRMS); Multiple Sclerosis

Summary: this protocol is part of a clinical study to evaluate efficacy and safety of multiple intravenous administrations of hb-admscs for the treatment of multiple sclerosis.

this clinical trial is designed as an open label, single center, phase 2 study to assess the efficacy and safety of multiple autologous adipose derived mesenchymal stem cells in patients with relapsing remitting multiple sclerosis. the trial includes a screening period of up to 4 weeks, a 32-week treatment period, and a safety follow-up period of 20 weeks after the last investigational product administration. this clinical trial will be opened to enroll up to 10 eligible subjects diagnosed with relapsing remitting multiple sclerosis. each eligible study subject will receive a total of 6 intravenous infusions of hb-admscs. study infusions will be administered with the following regimen, week 0, 4, 8, 16, 24 and 32, this dosing interval has been selected because due to the efficacy observed in the completed placebo-controlled counterpart to this study, hbms01 (ind 027633, nct05116540). efficacy was observed at the end of study visit (week 52), post-therapy with six infusions of hb-admscs. the following objectives will be investigated: efficacy as determined by the multiple sclerosis quality of life (msqol-54) instrument, efficacy as determined by changes in expanded disability status scale (edss), safety as determined by changes in patient health questionnaire (phq-9), and safety as determined by the incidence of adverse events or serious adverse events.
