What this trial studies

This follow-up study aims to evaluate the long-term safety and efficacy of SMUP-IA-01, a treatment derived from human umbilical cord blood mesenchymal stem cells, for patients with knee osteoarthritis. Participants who completed the initial Phase I trial will be monitored over a period of up to 60 months, with follow-up assessments occurring at 6, 12, 24, 36, 48, and 60 months post-treatment. The study will analyze the outcomes related to the treatment's effectiveness and any potential long-term side effects.

Who should consider this trial

Good fit: Ideal candidates are individuals who have previously participated in the Phase I trial of SMUP-IA-01 and completed the safety and efficacy evaluations.

Not a fit: Patients who did not participate in the initial Phase I trial or those deemed unsuitable by the principal investigator will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide valuable insights into the long-term benefits and safety of stem cell therapy for patients suffering from knee osteoarthritis.

How similar studies have performed: Other studies involving stem cell therapies for knee osteoarthritis have shown promise, but this specific follow-up evaluation is novel in its long-term focus.
