Evaluation of Safety and Exploratory Efficacy of CARTISTEM®, a Cell Therapy Product for Articular Cartilage Defects

Evaluation of Safety and Exploratory Efficacy of CARTISTEM®, a Cell Therapy Product for Articular Cartilage Defects: A Phase I/IIa Clinical Trial in Patients With Focal, Full-thickness Grade 3-4 Articular Cartilage Defects of the Knee

The purpose of this study is to determine whether CARTISTEM, a cell therapeutic product, is safe and effective in the treatment of articular cartilage defects of the knee as a result of ageing, trauma, or degenerative diseases.

Study Overview

• Status: Completed
• Conditions: Degeneration Articular Cartilage Knee
• Intervention / Treatment: Biological: CARTISTEM®

Detailed Description

Conventional treatment modalities have not been able to provide complete and sustained resolution of symptoms following damage to the articular cartilage. Despite the numerous techniques available today, complete healing of damaged or defective cartilage or consistent reproduction of normal hyaline cartilage does not occur, and continuous drug administration or secondary surgeries are common.

Research in mesenchymal stem cells has had a rapid acceleration over the past decade and MSC-based therapy has become one of the objects of investigation for a new branch of medicine termed regenerative medicine. This emerging technology shows great promise for producing transplantable cartilage constructs to restore the function of degenerated joints.

CARTISTEM®, a combination of human umbilical cord blood-derived mesenchymal stem cells and sodium hyaluronate, is intended to be used as a single-dose cellular therapeutic agent for cartilage regeneration in human subjects with cartilage defects of the knee as a result of ageing, trauma, or degenerative diseases.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
IKDC Score	Subjects underwent a self-assessment of knee function using the IKDC (International Knee Documentation Committee Assessment)subjective knee evaluation before and after the administration of the IP. The assessment is designed to detect improvement or deterioration in symptoms, function, and sports activities due to knee impairment. The possible score ranges from 0 to 100, where 100 = no limitation with daily or sporting activities and the absence of symptoms. The IKDC assessment was performed before IP administration and at Months 12 after IP administration in an exploratory fashion. The IKDC score from the Month 12 visit was used as a primary indicator of the post operative change. The outcome was presented with the post-operative change amount from the baseline.	12 months

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
VAS	Subjects underwent a self-assessment of joint pain using the 100-mm VAS (Visual Analogue Scale) before and at Months 12 and 24 after IP (investigational product) administration. Higher values represent worse joint pain. Use of NSAIDs and any other analgesics had to be discontinued for 48 hours and 24 hours, respectively, prior to the 100 mm VAS evaluation. The outcome was presented with the post-operative change amount at Months 12 and 24 from the baseline. 100-mm VAS scores range from 0 to 100. Higher values represent worse joint pain.	24 months
Lysholm Score	The Lysholm knee scoring scale is a self-assessment that rates the severity of common complaints related to knee problems, such as pain, swelling, abnormal sensations, and ability to squat or climb stairs. The possible score ranges from 0 to 100, where 100 = no symptoms or disability. Scores are categorized as excellent (95 to 100), good (84 to 94), fair (65 to 83), and poor (≤64). Subjects underwent a self-assessment of knee function using the Lysholm score before IP administration and at Months 12 and 24 after IP administration. The outcome was presented with the post-operative change amount at Months 12 and 24 from the baseline.	24 months
KOOS Score	The Knee Injury and Osteoarthritis Outcome score (KOOS) knee survey is a self assessment of knee function and knee-related quality of life (QOL). Subjects responded to each question regarding knee-related symptoms, swelling, pain, impaired function, or changes in QOL with 1 of 5 possible answers that range from "never/not at all" to "always/extremely." The possible score for each parameter ranges from 0 to 100, where 0=extreme problems and 100=no problems. Subjects completed the KOOS knee survey before IP (investigational product) administration and at Month 24 after IP administration. The outcome was presented with the post-operative change amount at Month 24 from the baseline.	24 months
IKDC Score	Subjects underwent a self-assessment of knee function using the IKDC subjective knee evaluation before and after the administration of the IP. The assessment is designed to detect improvement or deterioration in symptoms, function, and sports activities due to knee impairment. The possible score ranges from 0 to 100, where 100 = no limitation with daily or sporting activities and the absence of symptoms. The IKDC assessment was performed before IP administration and at Month 24 after IP administration in an exploratory fashion. The outcome was presented with the post-operative change amount at Month 24 from the baseline.	24 months
