Safety and Efficacy of AMT-RegeneraActiva in the Management of Knee Osteoarthritis (OA)
Study Details
Study Description
Brief Summary
The goal of this clinical trial is to compare in 60 patients suffering for Knee OA to demonstrate that AMT-RegeneraActiva is able to speed up the improvement process of knee osteoarthritis (OA) compared to Sodium Hyaluronate Participants will [describe the main tasks participants will be asked to do, treatments they'll be given and use bullets if it is more than 2 items].
Researchers will compare 2 Groups to see to demonstrate that AMT-RegeneraActiva is able to speed up the improvement process of knee osteoarthritis (OA) compared to Sodium Hyaluronate to pain management and improvement of functionality.

Detailed Description
All the patients participating in the study will have had been diagnosed with degenerative knee chondropathy from grade II to III of Kellgren-Lawrence grading scale and they will have signed a consent informed. The age rate established is from 25 to 65 years old. All the patients, except control group, will be treated with one unique articular injection of autologous micrografts obtained through the Rigenera® Technology. The control group will receive Sodium Hyaluronate (Hyalubrix 60 -1,5%-2ml vial). To assess the level of satisfaction of the patient, the reduction of pain, and the functional state of the articulation, Knee Osteoarthritis Outcome Score (KOOS) will be used, before the treatment, 3 months after the treatment, and at 6 months after the treatment.
The patients will be randomized as:
-
Group (Arm) 1: AMT-RegeneraActiva
-
Group (Arm) 2: Sodium Hyaluronate(Hyalubrix 60 -1,5%-2ml vial).
Patients in both treatment arms will be provided with paracetamol (500 mg/tablet) as rescue medication for relieving knee's pain. This will be taken as needed for pain with a maximum of 4 tablets or 2 grams of paracetamol per day up to 4 days per week.
If more rescue medication is needed for pain, (recorded as the 'Number of Rescue Medication Taken for pain' in the daily diary) the patient will be considered a treatment failure. Patients deemed treatment failures for rescue medication use will continue to participate in follow-up visits for safety.
During the study patients in both arms must report in a daily paper diary consumption of rescue medication, in particular, the following information will be collected:
Rescue paracetamol for OA:
-
Amount of rescue medication taken for OA in the past 24 hours.
-
Any non-rescue pain medication for OA or for pain other than OA
The consumption of rescue medication will be checked from the Investigators will be carefully documented at all visits during the study.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: AMT-Regenera activa All the patients of the group will be treated with one unique articular injection of autologous micrografts obtained through the Rigenera® Technology |
Device: AMT-Regenera activa
Patient's preparation: is an ambulatory procedure, the sterility of the Micrograft and the method should be guaranteed during the whole procedure.
Punch biopsy extraction:
The punch should be obtained by the posterior auricular shell area. The zone cleaned with antiseptic solution. Anesthesia is applied in the posterior zone in the base area of the auricular shell. It should be applied superficially to separate the skin from the cartilage . Should be obtained by 3 dermic punches of 2,5mm diameter. The skin is separated from the perichondrium and cartilage.
Once the samples are obtained, they must be put on the metallic grid of the Rigeneracon
Afterwards, 4 ml of Saline solution are added in the inferior part of the Rigeneracon, then close the lid and then put it in the machine with the needed adaptors.
The samples are processed for 6 minutes
The Rigeneracon is extracted from the machine.

| Active Comparator: Hyalubrix All the patients of the group will be treated with one unique articular injection of Sodium Hyaluronate (Hyalubrix 60 -1,5%-2ml vial) |
Device: Hyalubrix
Patients randomized in Group 2 Sodim Hyaluronate (Hyalubrix 60 -1,5%-2ml vial). NOTE: For the infiltration in the medial knee compartment treatment, the use of intramuscular needle is recommended.
The care post-treatment The homeostasis of the donor's area is achieved by mechanical compression. Usually, there is no need of stitches.
Often it can be seen a bit of inflammation during the first 24-72 hours. The use of analgesic drugs is recommended, avoiding the NSAID, they can interfere in the function of micrografts. Apply intermittently cold on the area or a compressive bandage, if needed

Outcome Measures
Primary Outcome Measures
- AMT Regenera improvement of pain management [6 months overall]
To demonstrate that AMT-RegeneraActiva is able to speed up the improvement process of knee osteoarthritis (OA) compared to Sodium Hyaluronate (Hyalubrix 60 -1,5%-2ml vial)to pain management and consequent improvement of functionality in patients with knee OA (grade II-III Kellgren-Lawrence grading scale) from baseline after unique administration of ATM Regenera-Activa treatment by interarticular injection. KOOS score will be tool to measurement of this performance
Secondary Outcome Measures
- IKDC improvement [6 months overall]
IKDC patient reported SCORE
