Study Description

Brief Summary:

This clinical study is to investigate the safety and efficacy of NCR100 injection in subjects with knee osteoarthritis (KOA). It is a dose-escalating, open label study in adult KOA subjects.

Condition or disease	Intervention/treatment	Phase
Knee Osteoarthritis	Biological: NCR100 injection	Phase 1

Detailed Description:

Knee osteoarthritis (KOA) is a kind of degenerative joint disease and there are over 300 million cases worldwide. The aim of this clinical trial is to evaluate the safety, tolerability, and efficacy of human pluripotent stem cell derived mesenchymal stromal cells (NCR100) injection in the treatment of subjects with knee osteoarthritis.

Study Design

• Study Type: Interventional (Clinical Trial)
• Estimated Enrollment: 12 participants
• Allocation: N/A
• Intervention Model: Sequential Assignment
• Masking: None (Open Label)
• Primary Purpose: Treatment
• Official Title: A Phase I, Open Label, Single Arm, Multiple Center, Dose Escalation Clinical Trial to Evaluate the Safety, Tolerability and Efficacy of Human Induced Pluripotent Stem Cell Derived Mesenchymal Stromal Cells (NCR100) Injection in the Treatment of Subjects With Knee Osteoarthritis
• Estimated Study Start Date: October 2023
• Estimated Primary Completion Date: June 2024
• Estimated Study Completion Date: May 2025

Arms and Interventions

Arm	Intervention/treatment
Experimental: NCR100 injection; Cohort1:Low dose NCR100 injection; Cohort2:Mid-low dose NCR100 injection; Cohort3:Mid-high dose NCR100 injection; Cohort4:High dose NCR100 injection.	Biological: NCR100 injection; Subjects will receive a one-dose intra-articular NCR100 injection.

Outcome Measures

Primary Outcome Measures :

1. Adverse Event(AE) or Serious Adverse Event(SAE) [ Time Frame: Week1,Week2,Week4 ]
   Number of participants with treatment-related adverse events or serious adverse events as assessed by CTCAE v5.0
2. Dose-Limiting Toxicity(DLT) [ Time Frame: 4 weeks after injection ]
   Number of participants with Dose-limiting toxicity in 28 days after injection

Secondary Outcome Measures :

1. Maximum plasma concentration(Cmax) [ Time Frame: 30minutes before administration,24hours,1week,2week,4week,8week,12week and 24week after administration ]
2. Elimination half life of drug(T1/2) [ Time Frame: 30minutes before administration,24hours,1week,2week,4week,8week,12week and 24week after administration ]
3. Time after doing at which maximun plasma concentration is reached(Tmax) [ Time Frame: 30minutes before administration,24hours,1week,2week,4week,8week,12week and 24week after administration ]
4. Area under the plasma concentration-time curve(AUC) [ Time Frame: 30minutes before administration,24hours,1week,2week,4week,8week,12week and 24week after administration ]
