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).
