简要总结
The goal of this clinical trial is to evaluate the safety, tolerability and efficacy of human umbilical cord mesenchymal stem cell injection (HS_SW01 cells injection) in patients with Ankylosing Spondylitis.
Participants will be required to sign the informed consent form and will only be assigned to the study and enrolled after undergoing a series of tests and meeting the inclusion and exclusion criteria of the protocol.
详细描述
This clinical trial is a multicenter Phase I/II clinical trial, which includes two stages: Phase I dose-escalation and Phase II dose-expansion. The Phase I dose-escalation stage adopts a single-arm design and aims to evaluate the safety, tolerability and preliminary efficacy of HS_SW01 cells injection in patients with Ankylosing Spondylitis. The Phase II dose-expansion stage is a randomized, double-blind, controlled study designed to evaluate the safety and efficacy of HS_SW01 cells injection in patients with Ankylosing Spondylitis.
During the Phase I, the trial includes three dose groups: 1.0×10^6 cells/kg, 2.0×10^6 cells/kg and 2.0×10^6 cells/kg. Using a "3+3" dose-escalation design, each dose group will enroll 4 to 7 subjects in sequential order from the lowest to the highest dose level.
Eligible participants are patients with Ankylosing Spondylitis between 18 and 65 years of age inclusive, who satisfy all the inclusion criteria and do not meet any of the exclusion criteria.

入选标准
- •Age 18 to 65 years, inclusive, male or female.
- •Voluntarily sign the informed consent form and comply with the requirements of this study protocol.
- •Participants must have a documented diagnosis of ankylosing spondylitis (AS) based on the modified 1984 New York criteria, as follows: (a) Inflammatory back pain for ≥3 months, improving with activity but not relieved by rest;; (b) Limited spinal motion in the lumbar spine (sagittal and frontal planes); (c) chest expansion reduced relative to normal values for age and sex. (d):Sacroiliitis on imaging: bilateral grade II-IV or unilateral grade III-IV. Diagnosis of AS requires fulfillment of criterion (d) plus any one of criteria (a)-(c). The diagnosis must be confirmed at both the screening and baseline visits.
- •Participants must have active AS at screening and baseline, defined as Ankylosing Spondylitis Disease Activity Score (ASDAS) ≥2.1, or Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) ≥
- •Participants must have received conventional therapy and, prior to randomization, must meet at least one of the following criteria for the following criteria, as confirmed by the investigator: (a) inadequate response to nonsteroidal anti-inflammatory drugs (NSAIDs): ≥4 weeks of continuous therapeutic-dose NSAID if one agent used; or ≥2 weeks of therapeutic-dose NSAID for each of ≥2 agents; (b) intolerance to NSAIDs: Discontinuation of NSAIDs due to treatment-related adverse events (e.g., allergic reactions, gastrointestinal symptoms or signs); the 4-week treatment duration is not required. (c) Contraindication to NSAID therapy: History of NSAID allergy, active gastrointestinal ulcer, bleeding, or other contraindications.
- •Participants who have previously received at least two biologic disease-modifying antirheumatic drugs (bDMARDs) must have received recommended doses for at least 12 weeks prior to randomization with inadequate response, or have been intolerant to at least one bDMARD treatment (e.g., unable to continue due to adverse drug reactions, allergic reactions, or other reasons).
- •Participants receiving concomitant oral corticosteroids or NSAIDs must be on a stable dose for at least 14 days before the baseline visit. Participants receiving conventional synthetic DMARDs (cDMARDs) must be on a stable dose for at least 28 days prior to the baseline visit.
- •Female participants must: Be of non-childbearing potential, defined as postmenopausal for at least 1 year or surgically sterilized; OR, If of childbearing potential, agree to use strict contraceptive measures from the time of signed informed consent through at least 6 months after the last dose of study drug, and have a negative serum pregnancy test at screening.
- •Participants must be considered in good general health based on medical history and physical examination performed at screening, as judged by the investigator.
- •Participants must voluntarily agree to receive disease education and be willing to maintain correct posture and perform appropriate physical exercise.
- •Participants must be willing and able to complete all study procedures and follow-up visits.
