The MANUS Trial aims to examine the safety, feasibility and potential efficacy of intramuscularly injected allogeneic mesenchymal stromal cells as treatment for digital ulcers of systemic sclerosis.
The MANUS Trial is a randomized double-blind, placebo-controlled clinical trial. Patients with systemic sclerosis (SSc) and digital ischemia with intractable ischemic digital ulcers refractory to conventional treatments are eligible to participate.
20 participants will be randomised (1:1) to undergo intramuscular injection (8 sites) of allogeneic bone marrow derived mesenchymal stromal cells (BM-MSC) (45-50*10^6) or placebo in the most affected limb.
Main study parameters/endpoints: The primary outcome is the toxicity of the treatment at 12 weeks after MSC administration, defined as
Secondary outcome measures are: number of serious adverse events, pain and disability parameters; healing, time to healing and reduction of new ischemic digital ulcers; modified Rodnan skin score; Scleroderma Health Assessment Questionnaire (S-HAQ) including visual analogue scales (VAS) for scleroderma-specific symptoms; Quality-of-life (SF-36, EuroQol (EQ-5D); Cochin hand function score. We will also evaluate changes in capillary morphology and architecture using capillaroscopy; biochemical parameters; markers for endothelial activation and injury, inflammation, oxidative stress, circulating cells including endothelial cells, hematopoietic and endothelial progenitor cells, cytokines and growth factors, immunological responses. Follow-up visits will be scheduled at 48 hours and 2, 4, 8, 12, 24 and 52 weeks post-treatment.
