Ankylosing Spondylitis | A Molecule Basic Study of Early Warning for New Pathogenic Risk of Ankylosing Spondylitis

Ankylosing Spondylitis research study

What is the primary objective of this study?

The investigators will recruit active ankylosing spondylitis patients for injection treatment of Human Mesenchymal Stem Cells (a prospective, open-label, masculine medicine controlled(NSAIDs), clinical trial), and collect their Peripheral Blood Lymphocyte (PBMCs) and sera before and after the treatment of 24 weeks to test the gene expression profiles and study related pathogenesis of AS

Which medical condition, disease, disorder, syndrome, illness, or injury is researched?

Ankylosing Spondylitis

Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Biological:MSChuman mesenchymal stem cells,1*10^4-6 cells /Kg , IV (in the vein) on day 1 of each 14-60 day cycle,1-6 times treatment. a total of 24 weeks for follow up.

Drug:"celecoxib", "Celebrex®"non-steroid anti-inflammatory drugs (NSAID):"celecoxib", "Celebrex®" 0.2g Bid(twice a day),PO (Per Os);a total of 24 weeks for follow up

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.

MSC plus NSAIDhuman mesenchymal stem cells:1*10^4-6 cells /Kg , IV (in the vein) on day 1 of each 14-60 day cycle,1-6 times treatment, plus non-steroid anti-inflammatory drugs (NSAID: "celecoxib", "Celebrex®" 0.2g Bid(twice a day),PO (Per Os). Duration of treatment:24 weeks for follow up. collect peripheral blood (PBMCs and serums)of those patients at baseline and every 4 weeks for basic study after they signed informed consent.

NSAIDnon-steroid anti-inflammatory drugs (NSAID: "celecoxib", "Celebrex®" 0.2g Bid(twice a day),PO (Per Os);a total of 24 weeks for follow up;collect peripheral blood (PBMCs and serums)of those patients at baseline and every 4 weeks for basic study after they signed informed consent.
