Mesenchymal Stromal Cells as Treatment for Digital Ulcers in Systemic

Status Recruiting

Clinical Trial Summary

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.

Clinical Trial Description

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 1. Local toxicity, including signs of local inflammation (swelling, warmth, impairment of function), worsening of ulcers or new ulcers or hematomas after MSC administration 2. Other adverse events, graded according to the Common Terminology Criteria for Adverse Events version 4.0, expressed as maximum grade toxicity per organ system. 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. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
