Abstract

Aims: This phase I trial assessed the safety and potential efficacy of monthly 3 dose intravenous infusion of allogeneic bone marrow-derived clonal mesenchymal stromal cells (BM-cMSCs) in refractory rheumatoid arthritis (RA) patients over 24 weeks.

Patients & methods: Six patients with refractory RA received BM-cMSC infusions at one-month intervals over a 24-week period. Safety outcomes included adverse events (AEs) and serious adverse events (SAEs). Clinical efficacy was assessed using the Visual Analog Scale (VAS), Simple and Clinical Disease Activity Indices (SDAI/CDAI), Health Assessment Questionnaire (HAQ), and American College of Rheumatology (ACR) response criteria. Serological makers including: erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), IL-10, IL-17, TNF-α, and Treg/Th17 ratios were measured.

Results: BM-cMSC infusions were well-tolerated, with no SAEs reported. VAS scores improved in three patients, with two achieving sustained pain relief and quality-of-life enhancement. Four patients met ACR20 at week 16, while SDAI and CDAI scores indicated disease activity reduction in three patients. Anti-CCP and RF levels showed variable responses, with some increases not consistently correlating with clinical outcomes. Serological biomarkers showed mixed results; IL-10 increased in five patients, while pro-inflammatory markers TNF-α and IL-17 decreased in the same individuals.

Conclusions: BM-cMSC therapy demonstrated a favorable safety profile and potential efficacy in managing refractory RA. While preliminary results are promising, further studies with larger cohorts and long-term follow-up are needed to validate these findings and optimize therapeutic strategies.

Clinical trial registration: IRCT20080728001031N29.

期刊介绍： Regenerative medicine replaces or regenerates human cells, tissue or organs, to restore or establish normal function*. Since 2006, Regenerative Medicine has been at the forefront of publishing the very best papers and reviews covering the entire regenerative medicine sector. The journal focusses on the entire spectrum of approaches to regenerative medicine, including small molecule drugs, biologics, biomaterials and tissue engineering, and cell and gene therapies – it’s all about regeneration and not a specific platform technology. The journal’s scope encompasses all aspects of the sector ranging from discovery research, through to clinical development, through to commercialization. Regenerative Medicine uniquely supports this important area of biomedical science and healthcare by providing a peer-reviewed journal totally committed to publishing the very best regenerative medicine research, clinical translation and commercialization. Regenerative Medicine provides a specialist forum to address the important challenges and advances in regenerative medicine, delivering this essential information in concise, clear and attractive article formats – vital to a rapidly growing, multidisciplinary and increasingly time-constrained community. Despite substantial developments in our knowledge and understanding of regeneration, the field is still in its infancy. However, progress is accelerating. The next few decades will see the discovery and development of transformative therapies for patients, and in some cases, even cures. Regenerative Medicine will continue to provide a critical overview of these advances as they progress, undergo clinical trials, and eventually become mainstream medicine.
