NCT05962762

Brief Summary

The goal of this clinical trial is to evaluate the safety and tolerability of multiple doses of human umbilical cord mesenchymal stem cell injection in patients with Ankylosing Spondylitis, and to further explore the efficacy, pharmacodynamic profile and appropriate dose of administration to provide a basis for the use of safer and more effective treatments for patients with Ankylosing Spondylitis in the future. Participants are required to sign an informed consent form and, after undergoing a series of tests and meeting the protocol's entry and exclusion criteria, are assigned to a dose group for intravenous infusion of human umbilical cord mesenchymal stem cells.

Study Arms (1)

Human Umbilical Cord Mesenchymal Stem Cell Injection

EXPERIMENTAL

The trial was divided into three dose groups: Low-dose group: 1000000 cells/kg Medium-dose group: 3000000 cells/kg High-does group: 5000000 cells/kg

Biological: Human Umbilical Cord Mesenchymal Stem Cells

Interventions

The trial was conducted sequentially from the low dose group to the high dose group, with 3-6 subjects enrolled in each dose group. The trial was conducted on a case-by-case basis in the high dose group, with each subject in the high dose group being enrolled in subsequent subjects only after completion of at least 7 days of post-dose safety observation. Each subject received only one corresponding dose. All subjects received experimental drugs and conventional treatment during the study period. All subjects in each test dose group will complete a 4-week (28-day) dose-limiting toxicity (DLT) After the observational evaluation period, a decision will be made by the investigator and sponsor based on a discussion of relevant safety data whether to start the next dose group.

You may qualify if:

  • A definitive diagnosis of ankylosing spondylitis (AS) (according to the 1984 New York Revised Criteria, Annex 1) with active AS.
