Intervention / Treatment |
---|---|
Experimental: Chondrochymal® group
Subjects will be IA injected at the target knee with 3 mL of Chondrochymal® containing 5.0 x 107 BM-MSCs in lactated Ringer's solution at Day 1.
|
The bone marrow mesenchymal stem cells (BM-MSCs) in Chondrochymal® for this study was obtained from the donor recruited in Taipei Veterans General Hospital, Taiwan.
Donors aged 20 to 50 and tested negative to infection of human immunodeficiency virus type 1 and 2 (HIV-1/2), hepatitis B virus (HBV), hepatitis C virus (HCV), Cytomegalovirus (CMV), Treponema pallidum (syphilis), human T-lymphotropic virus types I and II (HTLV-I/II), and Tuberculosis (TB) were enrolled.
The eligible donor's bone marrow was aspirated from the iliac crest or femur.
The collected BM-MSCs were then cultured, expanded and cryopreserved in a Good Tissue Practice (GTP)-complied laboratory.
The qualified cells in cryopreservation meeting the release criteria will be thawed, mixed with lactated Ringer's solution, and transferred into a sterile syringe as the final product.

Primary Outcome Measures

Measure Description |
Time Frame |
---|---|---|
Efficacy-Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) assessment
Time Frame: Week 24
|
Change from baseline in the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain score on the target knee at Week 24. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC LK 3.1) is applied extensively to patients with osteoarthritis of the hip or knee. It is a 24-item patient-reported questionnaire with a total score ranging from 0 to 96. The sub-scores range from 0 to 4 for each item with a higher score indicating a more severe OA symptom. The WOMAC includes 3 domains: (1) Pain: 5 items (score range: 0 to 20), (2) Stiffness: 2 items (score range: 0 to 8), and (3) Functional limitation: 17 items (score range: 0 to 68). For ease of interpretation, WOMAC scores (including total scores and sub-scores) will be linearly transformed to a 0 to 100 scale. |

Efficacy-Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) assessment
Time Frame: Week 4、Week 12、Week 24、Week 36、Week 52
|
Change from baseline at each post-treatment visit during the Evaluation Period on the target knee in total scores and sub-scores of each section of WOMAC. The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC LK 3.1) is applied extensively to patients with osteoarthritis of the hip or knee. It is a 24-item patient-reported questionnaire with a total score ranging from 0 to 96. The sub-scores range from 0 to 4 for each item with a higher score indicating a more severe OA symptom. The WOMAC includes 3 domains: (1) Pain: 5 items (score range: 0 to 20), (2) Stiffness: 2 items (score range: 0 to 8), and (3) Functional limitation: 17 items (score range: 0 to 68). For ease of interpretation, WOMAC scores (including total scores and sub-scores) will be linearly transformed to a 0 to 100 scale. |
Week 4、Week 12、Week 24、Week 36、Week 52
|
Efficacy-Visual Analogue Scale (VAS) assessment
Time Frame: Week 4、Week 12、Week 24、Week 36、Week 52
|
Change from baseline at each post-treatment visit during the Evaluation Period on the target knee in the Visual Analogue Scale (VAS) for pain. The Visual analog scale (VAS) pain assessment measures pain intensity. It is a scale of 10 cm in length, representing the subject's pain intensity with higher scores indicating more severe pain. VAS score ranges from 0 to 10 cm, and will be transformed to a "0 to 100" mm scale. |
Week 4、Week 12、Week 24、Week 36、Week 52
|
Efficacy-SF-36 Quality of Life (QoL) health survey questionnaire
Time Frame: Week 4、Week 12、Week 24、Week 36、Week 52
|
Change from baseline at each post-treatment visit during the Evaluation Period in the domain scores and total score of SF-36 Quality of Life (QoL) health survey questionnaire. The SF-36 Quality of Life (QoL) health survey questionnaire (v2.0) is a standardized, self-evaluated measurement of health status. It has 36 questions to measure functional health and well-being from the patient's point of view. The SF-36 QoL questionnaire consists of 8 scaled scores in various health domains including 4 items in vitality, 10 items in physical functioning, 2 items in bodily pain, 5 items in general health perceptions, 4 items in physical role functioning, 3 items in emotional role functioning, 2 items in social role functioning, and 5 items in mental health. The score for each domain will be transformed to a scale from 0 to 100, on which zero corresponds to "worst health status" and 100 to "best health status". |
Week 4、Week 12、Week 24、Week 36、Week 52
|
Efficacy-Whole-Organ Magnetic Resonance Imaging Score (WORMS)
Time Frame: Week 24、Week 52、Week 104
|
Changes from baseline in Whole-Organ Magnetic Resonance Imaging Score (WORMS) of the target knee. MRI performed on the target knee will be used to evaluate the Whole-Organ-MRI Scores (WORMS). The WORMS, diffusion mapping (apparent diffusion coefficient [ADC] and fractional anisotropy [FA]), and T2 map values (it is a value from the worst region for screening visit), will be recorded in the CRF to evaluate the effect on knee cartilage response. WORMS are used to evaluate the articular cartilage lesions at three joints, including 14 anatomic compartments as follows (Peterfy et al., 2004) |
Week 24、Week 52、Week 104
|
Efficacy-knee joint space width (JSW)
Time Frame: Week 24、Week 52
|
Change from baseline in knee joint space width (JSW) of the target knee.
Knee X-ray for knee joint space width (JSW) assessment will be performed on anterior-posterior (AP) view, Rosenberg's view, and axial view of patella 45° (lateral part and medial part).
X-ray will be performed for both knees at Screening Visit, while only for the target knee at the other scheduled visits.
|
Week 24、Week 52
|
Efficacy-synovial fluid
Time Frame: Week 52
|
Change from baseline in the synovial fluid analysis of the target knee at Week 52, if the subject's knee is suitable for arthrocentesis per investigator's judgment. The volume of synovial fluid aspiration will be determined by the investigator and will be recorded in the CRF. The appearance, white blood cell count (WBC), red blood cell count (RBC), lymphocytes, monocytes, and neutrophils will be examined. |
Week 52
|
Efficacy-rescue medication
Time Frame: Week 4 to Week 52 、Week 24 to Week 104

Percentage of subjects using the rescue medication(s) during Visit 3 to Visit 7 and Visit 3 to Visit 8. Subjects are allowed to take acetaminophen and/or designated NSAID as rescue medicine to reduce the pain when needed. The acceptable NSAIDs are Etoricoxib and Celebrex. The maximum oral doses for acetaminophen, Etoricoxib, and Celebrex are ≤ 2000 mg/day, ≤ 120 mg/day, and 200 mg/day, respectively, while the topical use of these three rescue medications is allowed at any dose levels. |
Week 4 to Week 52 、Week 24 to Week 104
