NCT06082440 | Unknown Early Phase 1

• 1 other identifier: QWang
• Study Type: interventional
• Target: 18
• Locations: 1 country
• Sites: 1

Brief Summary

The goal of this clinical trial is to evaluate the safety and tolerability of human umbilical cord mesenchymal stem cells mediated by arthroscopy in patients with knee osteoarthritis. This experiment proposes to enroll 18-22 patients. The experimental drug is human umbilical cord mesenchymal stem cells.

Conditions

Osteoarthritis, Knee

Outcome Measures

Primary Outcomes (2)

• Within 4 weeks after treatment, evaluate the incidence and severity of adverse events.

  According to the NCI CTCAE v5.0 grading standard, adverse events in the study will be described and the level of them assessed. Then it will be counted up that the number and incidence of drug-related adverse events/adverse reactions, serious adverse events/serious adverse reactions (level 3 or above), and adverse events/adverse reactions leading to withdrawal in each group during the treatment period.

  Within 4 weeks after treatment

• Within 4 weeks after treatment, evaluate the Maximum Tolerable Dose (MTD).

  The degree of adverse events observed in the experiment will be determined according to the NCI CTCAE v5.0 grading standard. If there were drug-related adverse events of level 3 or above that occurred in half or more of the subjects in any dose group before the dose was reached 1.0 × 10\^8 cells/person/time, the dose ramp would be terminated and then the previous dose would be defined as MTD. If not, define 1.0 × 10\^8 cells/person/time as MTD.

  Within 4 weeks after treatment

Secondary Outcomes (6)

• Evaluate changes on the scores of the Western Ontario and McMaster Universities Osteoarthritis Index relative to baseline after treatment

  Baseline, Week 4, Week 12, Week 24 and Week 48

• Evaluate changes on the degree of the Kellgren-Lawrence grading standard for Knee joint X-ray relative to baseline after treatment

  Baseline, Week 24 and Week 48

• Evaluate changes on the degree of the Kellgren-Lawrence grading standard for Knee joint MRI relative to baseline after treatment

  Baseline, Week 24 and Week 48

• Evaluate changes on the level of inflammatory factors relative to baseline after treatment

  Baseline, Week 4, Week 12, Week 24 and Week 48

• Evaluate changes on the scores of the Visual Analogue Scale relative to baseline after treatment

  Baseline, Week 4, Week 12, Week 24 and Week 48
