About this study

Official title: Treatment of Knee Arthrosis: Platelet-derived Growth Factors vs. Hyaluronic Acid. A Phase II-III Randomized Controlled Trial

Primary aim of this trial was to assess efficacy three intraarticular injections of platelet lysate when compared to hyaluronic acid. Additional objectives were to compare the treatment groups in terms of a number of functional scales and of number of adverse events.

Read the detailed description

Intra-articular injections of hyaluronic acid are effective in improving symptoms and slow disease progression, but are not able to revert the damage mechanism and trigger cartilage healing.

Growth factors included in PRP could stimulate cartilage repair, normalize synovial fluid viscoelasticity, induce a correction in tissue damage, improve articular function, control pain and ameliorate quality of life.

Primary aim of this trial was to assess, among patients with grade II/III osteoarthrosis of the knee, efficacy (as determined by improvement at MRI 6 months after the first injection) of three intraarticular injections of platelet lysate when compared to hyaluronic acid. Additional objectives were to compare the treatment groups in terms of a number of functional scales (WOMAC, Lysholm, Tegner Knee, Scale, AKS, Lequesne, VAS) and of number of adverse events.

Being tested

What participants receive

Study groups in NCT02958761
Study groupRoleWhat they receive
Platelet-rich plasmaExperimentalPatients in the intervention group will receive three autologous PRP plus calcium gluconate (as activator) intraarticular injections at 4-week intervals. Briefly, at the Immunohaematology and Transfusion Service, on each scheduled visit 20 ml of autologous whole blood will be sampled from each patient, 2 ml ACD-A will be added directly the syringe as anticoagulant; finally the vial will be gently centrifuged at 900rpm for 7 minutes. Platelet-rich plasma was collected. The PRP vials plus activator will be immediately shipped to the rehabilitation unit, where intraarticular injection will be performed by an experienced physiatrist.

What is being measured

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

  1. Efficacy (as determined by improvement at MRI 6 months after the first injection) of intraarticular injections of platelet lysate

    Each knee was improvement, from baseline, by at least one degree the maximum MRI score (Shahriaree Classification System - modified) at 6 month

    Measured: Six months after the last infiltration

Secondary outcomes (7)
  1. WOMAC functional scale

    multilevel generalized linear models (for panel-data) with interaction between time and treatment group

    Measured: At baseline (prior to treatment), at 15 days form the last injection, 6 months from the last infiltration and at 1 year

  2. Lysholm functional scale

    multilevel generalized linear models (for panel-data) with interaction between time and treatment group

    Measured: At baseline (prior to treatment), at 15 days form the last injection, 6 months from the last infiltration and at 1 year

  3. Tegner Knee functional scale

    multilevel generalized linear models (for panel-data) with interaction between time and treatment group

    Measured: At baseline (prior to treatment), at 15 days form the last injection, 6 months from the last infiltration and at 1 year

  4. AKS functional scale

    multilevel generalized linear models (for panel-data) with interaction between time and treatment group

    Measured: At baseline (prior to treatment), at 15 days form the last injection, 6 months from the last infiltration and at 1 year

  5. Lequesne functional scale

    multilevel generalized linear models (for panel-data) with interaction between time and treatment group

    Measured: At baseline (prior to treatment), at 15 days form the last injection, 6 months from the last infiltration and at 1 year

  6. VAS for pain

    multilevel generalized linear models (for panel-data) with interaction between time and treatment group

    Measured: At baseline (prior to treatment), at 15 days form the last injection, 6 months from the last infiltration and at 1 year

  7. Adverse event

    number of patients and knees with adverse event (any); anticipated potential adverse events were infection, anaphylaxis, hematoma

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing intraarticular injections of platelet lysate and hyaluronic acid in people with Knee Osteoarthrosis, run by Fondazione IRCCS Policlinico San Matteo di Pavia.

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 0 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: finished, as of the sponsor's last update on 9 Nov 2016. Status can change between updates, so confirm with the study contact before making plans.

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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Efficacy (as determined by improvement at MRI 6 months after the first injection) of intraarticular injections of platelet lysate (time frame: Six months after the last infiltration). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 9 Nov 2016.
