Brief Summary

In recent years, the incidence rate and disability rate of osteoarthritis have continued to grow, and it has become a common chronic disease of elderly patients, second only to the "three highs", and poses a continuous threat to China's medical and health system and public health system. Knee osteoarthritis is the main type of osteoarthritis, ranking 11th in global disability diseases and 38th in disability adjusted life year loss, causing significant economic burden to patients, families, and society. At present, most of the treatment methods for KOA have limited efficacy, only relieving pain symptoms and cannot prevent cartilage damage and other tissue damage in the joints. Due to the limitations of adverse events, there is still no optimal treatment plan for KOA. Most studies believe that autologous mesenchymal stem cell transplantation is a new treatment method with good efficacy and good repair effect for mild to moderate cartilage defects. Given that there is currently no optimal treatment plan for KOA, human umbilical cord mesenchymal stem cell injection has potential development value and is of great significance for the treatment of KOA patients.

Outcome Measures

Primary Outcomes (1)

  • Adverse Events

    Incidence and severity of adverse events after administration (CTCAE 5.0)

    From Baseline (0 W) to 4 weeks after treatment

Secondary Outcomes (5)

  • WOMAC (Western Ontario and McMaster Universities Arthritis Index,with the minimum value 0, and the maximum value 240, and higher scores mean a worse outcome)

    From Baseline (0 W) to 24 hours, 4 weeks, 12 weeks, 24 weeks, 48 weeks after treatment

  • VAS (Visual Analogue Scale,with the minimum value 0, and the maximum value 10, and higher scores mean a worse outcome)

    From Baseline (0 W) to 24 hours, 4 weeks, 12 weeks, 24 weeks, 48 weeks after treatment

  • Changes in knee joint range of motion from baseline

    From Baseline (0 W) to 4 weeks, 12 weeks, 24 weeks, 48 weeks after treatment]

  • Changes in X-Kellgren-Lawrence grading and minimum joint space width (mJSW) from baseline

    From Baseline (0 W) to 24 weeks, 48 weeks after treatment

  • Changes of MRI-Roberts cartilage repair score, cartilage thickness and synovial inflammation score (reference MOAKS) compared with baseline

    From Baseline (0 W) to 24 weeks, 48 weeks after treatment

Study Arms (3)

1UC-MSCs Treatment Group

EXPERIMENTAL

Participants will receive conventional treatment plus 1 time of UC-MSCs (5×10\^6 UC-MSCs/2.5mL, single injection into the knee cavity).

Drug: UC-MSCs

2UC-MSCs Treatment Group

EXPERIMENTAL

Participants will receive conventional treatment plus 1 time of UC-MSCs (1×10\^7 UC-MSCs/2.5mL, single injection into the knee cavity).

Drug: UC-MSCs

3UC-MSCs Treatment Group

EXPERIMENTAL

Participants will receive conventional treatment plus 1 time of UC-MSCs (2×10\^7 UC-MSCs/2.5mL, single injection into the knee cavity).

Drug: UC-MSCs

Interventions

In this study, three dose groups are preset, which are low-dose group: 5×10\^6 cells/2.5mL; medium-dose group: 1×10\^7 cells/2.5mL; high-dose group: 2×10\^7cells/2.5mL, 9 to 18 subjects will be recruited, and will be sequential from the low-dose group to the high-dose group according to the "3+3" dose escalation principle. At least 3 subjects are enrolled in each group for the safety and tolerability test of single administration. After the last subject in each dose group completes the DLT observation period, the sponsor and the researcher jointly confirm the safety tolerance of the subjects in the previous dose group, and only after the safe tolerance is determined can the subjects enter the next dose group, so as to evaluate the safety and tolerance of human umbilical cord mesenchymal stem cell injection in the treatment of knee osteoarthritis. Recommend appropriate cell therapy dose (RP2D) for Phase II clinical trials.
