About the trial

What the trial wants to find out

The MAST-GR study is a randomized controlled interventional trial with parallel treatment arms and 1:1 allocation

Read full original descriptionShow less

The primary objective of the study is to compare the safety and efficacy of a single intra-articular infiltration of Bone marrow aspirate concentrate (BMAC) with one of minimally manipulated adipose tissue (MM-AT) so as to determine the most effective cellular product in treating patients with knee osteoarthritis (OA).

The secondary objective is to demonstrate whether intra-articular infiltration of BMAC or MM-AT can induce disease-modifying effects in knee OA by imaging and biological assessments on peripheral blood.

The tertiary objective of the study is to identify factors that influence the clinical response to treatment (baseline characteristics of patients, biological characteristics of the treated knee, characteristics of cellular products, BMAC and MM-AT).

The 2 groups in the trial

  • single intra-articular injection of BMACTreatment being tested

    Patients randomized in this group will undergo single knee intra-articular injection of bone marrow aspirate concentrate (BMAC)

    Treatment: Bone marrow aspirate concentrate injection

  • single intra-articular injection of MM-ATTreatment being tested

    Patients randomized in this group will undergo single knee intra-articular injection of minimally manipulated adipose tissue (MM-AT)

    Treatment: intra-articular injection of Minimally manipulated adipose tissue

Questions to ask the study team

  1. How often do I need to come in, and for how long each time?
  2. Are travel costs paid?
  3. Can I keep my own doctor?
  4. What happens if I want to stop?
