Mycophenolate After Stem Cell Transplant for Systemic Sclerosis (IMPACT-SSc)
Immunomodulatory Maintenance Therapy Post-Autologous Hematopoietic Stem Cell Transplantation for Prevention of Systemic Sclerosis Relapse: A Pilot Randomized Trial
A pilot single center randomized trial to test whether a full-scale RCT evaluating the role of post-AHSCT maintenance immunosuppression with MMF in preventing disease relapse is feasible .
We are studying whether a brief course of treatment with MMF after AHSCT will serve to prevent disease relapse.

상세 설명
This study is performed determine the feasibility of a larger pragmatic RCT to evaluate the effectiveness of post- Autologous Hemopoietic Stem Cell Transplant (AHSCT) maintenance therapy with mycophenolate mofetil (MMF) in the prevention of Systemic sclerosis (SSc) relapse.
The study will include 6 participants who will be randomized at 1:1 ratio to treatment (MMF) or control arm (no treatment) for 6 months.
The participants will have 6 visits in total : An initial clinic visit will occur prior to stem cell collection. Post-AHSCT, in-person follow-up visits are scheduled on days 30, 90, 180, 270, and 300, with windows of +/- 1 week for days 30 and 90 and +/- 2 weeks for days 180, 270 and 300.
These visits will be coordinated at an established multidisciplinary (Rheumatology + Cell Therapy) clinic that are part of the patient's clinical care. At each visit, the participants will be asked to complete health questionnaires and laboratory tests will be performed as part of the standard of care of AHSCT recipients.
