Not Applicable
Active, not recruiting
- Conditions
- Ovary Cancer
- Interventions
- Biological: METR-NK cell（metabolic remodeling nature killer cells）
- Registration Number
- NCT07096583
- Lead Sponsor
- Anhui Provincial Cancer Hospital
- Brief Summary
To evaluate the remission effect and safety of intravenous injection of METR-NK cells as adjuvant therapy on bone marrow suppression in patients with ovarian cancer after chemotherapy
- Detailed Description
100 mL METR-NK cells were diluted in 500 mL 0.9% sodium chloride normal saline at 37℃, and the infusion volume of METR-NK cells was not less than 2×107 cells/kg for 1 day as a course of treatment, and the infusion time was maintained for 30 minutes on the 10th day before chemotherapy.

- Primary Outcome Measures
Name Time Method The remission rate of bone marrow suppression 3-month The objective of the study was to evaluate the efficacy and safety of NK cell adjuvant therapy in alleviating chemotherapy-induced myelosuppression in patients with ovarian cancer. The primary endpoints included the time to neutrophil recovery, the improvement rate of platelet count, and the incidence of infectious events
- Secondary Outcome Measures
Name Time Method Adverse event 12-month Any adverse medical event that occurred after the subject received the trial drug
