Clinical Trial Summary

The treatment of osteoarthritis (OA) of the knee remains still controversial. Despite that fact advanced stages with symptomatic and functional improvement are obtained with total knee replacement, however, there is no treatment that neither modifies the natural history of this disease, nor avoid joint replacement surgery in young patients in whom the prosthesis has conflictive indications. Moreover, prosthetic surgery leads to lower long-term survival and in older patients, higher morbidity and mortality. Cell therapy promises to be a treatment option through the use of mesenchymal cells with the capacity control inflammatory responses and trigger the differentiation into chondrocytes. Here we propose a randomized placebo-controlled clinical trial to evaluate radiologic and clinical outcomes in patients with knee OA.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Changes in Visual Analogue scale (VAS)	The pain VAS is a unidimensional measure of pain intensity, used to record patients' pain progression, or compare pain severity between paints with similar conditions. Score ranges from 1 to 10, where 1 means lowest pain and 10 relates to highest pain	30 months (day 0, day 1, month 1, month 3, month 6, year 1 and year 2
Primary	Changes in Knee Injury and Osteoarthritis Outcome Score (KOOS)	KOOS reflects the individual disease burden and overall joint health. KOOS consists of 5 subscales; Pain, other Symptoms, Function in daily living (ADL), Function in sport and recreation (Sport/Rec) and knee related Quality of life (QOL). The previous week is the time period considered when answering the questions. A normalized score (100 indicating no symptoms and 0 indicating extreme symptoms) is calculated for each subscale	30 months (day 0, month 3, month 6, year 1 and year 2)
Primary	Radiological changes in Magnetic resonance observation of cartilage repair tissue (MOCART 2.0)	MOCART score was introduced based on 7 pertinent variables that facilitate a standardized, reproducible, semiquantitative approach for the morphological assessment of cartilage repair. Variables assesed in MOCART are: 1. Degree of cartilage defect; 2. integration into adjacent cartilage; 3. surface of the repair tissue; 4. structure of the repair tissue; 5. signal intensity of repaired tissue; 6. bony defect or bony overgrowth; 7. subchondral changes. The score ranges between 0 and 100, being 100 the maximum level of tissue compromise	30 Months (day 0, year 1 and year 2)
