About this study

This is a clinical trial, unicentric, prospective, controlled, randomized, double blind during the experimental phase A.

In the experimental phase B, it is contemplated to administer the experimental treatment to the subjects included in the group treated with P-PRP in the event that the first treatment would be significantly more effective, both from a clinical and regenerative point of view

Read the detailed description
  • Main objective
  1. Confirm the presence of patellar tendon gap regeneration after the peritendinous and intratendinous infusion of MSV and compare it with the P-PRP group, evaluated by ECO, NMR and UTC.
  2. To evaluate the clinical efficacy of infusion of MSC in refractory patellar tendinopathy compared with the P-PRP group through the subjective clinical evolution of the patient, the EVA and VISA-P questionnaires and the strength of the extensor muscle group measured by dynamometry.
  • Secondary objective 1. To evaluate the feasibility and safety of the advanced therapy medication MSV and P-PRP when applied by percutaneous infusion into the body of the patellar tendinosis, verifying that each of the procedures established in the protocol is feasible and recording the possible adverse effects related with both treatments and adverse events arising during the period of the clinical trial, whether or not related to it
Being tested
mesenchymal stem cells, Pure platelet-rich plasma

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • mesenchymal stem cellsProcedure or surgery

    Autologous bone marrow aspiration is used as a cellular source to obtain MSVs and is subjected to the protocolized anticoagulant procedure. After checking the perfect condition of the shipment and the correct completion of the documentation that accompanies it, the processing of the bone marrow will be carried out.

    The processing of the bone marrow will be done in the Cell Therapy Unit of the IBGM under NCF, within 24 hours of the completion of the aspiration

  • Pure platelet-rich plasmaProcedure or surgery

    Under aseptic conditions, in surgical medium, 6 ml of P-PRP will be obtained from 36 ml of autologous peripheral venous blood sample.

    The plasma coagulation will be activated by the addition of Cl2Ca at a concentration of 5%.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Improvement in the tendon ecotexture

    The patellar tendon will be examined longitudinally and transversely using gray scale and color, exerting a minimum pressure with the probe. Images will be recorded in static and dynamic formats to develop a consensus of the findings.

    Measured: 24 months

Secondary outcomes (4)
  1. Presence of patellar tendon regeneration by the peritendinous and intratendinous infusion of MSV patellar tendinopathy compared to the P-PRP group

    Using ECO, RMN and UTC (Ultrasound Tissue Characterisation)

    Measured: 24 months

  2. the strength of the extensor muscle group

    using dynamometry.

    Measured: 24 months

  3. subjective clinical evolution of the patient

    Using EVA and VISA-P (Victorian Institute of Sport Assessment (patelar)) questionnaries.

    Measured: 24 months

  4. strength of the extensor muscle group

    Using dynamometry

    Measured: 24 months

Questions about this trial

What is this clinical trial studying?

A study testing mesenchymal stem cells and Pure platelet-rich plasma in people with Patellar Tendinopathy, run by Institut de Terapia Regenerativa Tissular at 1 site in Spain.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 19 Dec 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Improvement in the tendon ecotexture (time frame: 24 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03454737, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Dec 2018.
