Autologous BMA vs Saline and LAM + LP-PRP vs Saline Evaluations in Knee OA

Conditions
Summary
ABLE OA is a Health Canada authorized (phase II/III) trial \[Parent Control #: 263591\]. A multi-center, prospective, double-blinded, randomized, placebo-controlled adaptive trial to evaluate the efficacy of two minimally manipulated autologous cellular preparations i) bone marrow aspirate (BMA) injection; and, ii) combined lipoaspirate micronized (LAM) and leukocyte poor (LP) platelet-rich plasma (PRP) injections for the treatment of knee osteoarthritis (OA). BMA, LAM from lipoaspirate (LA), and LP-PRP from whole blood will be prepared using the Cervos Marrow Cellution™ Bone Marrow Aspiration System, Cervos LIPO-PRO™ Adipose Transfer System, and Cervos KEYPRP Platelet Separator System, respectively. Patient-reported outcome (PRO) measures will be collected using web- or paper-based questionnaires administered at baseline (pre-injection) as well as at 3, 6 and 12 months (post-injection). Blood, synovial fluid, and urine samples will be collected at baseline pre-injection and 6 months post-injection only.

Interventions
Participants will undergo a bone marrow aspiration. About 10 mL of BMA will be collected from the posterior iliac spine i.e., ipsilateral and/or contralateral iliac crest using the Cervos Marrow Cellution™ kit. The BMA does not require processing using a centrifuge after collection. 9 mL (or less) of BMA is injected into the osteoarthritic knee joint after collection (Arm A, Study 1).
Participants will undergo a bone marrow aspiration to collect about 10 mL of BMA from the posterior iliac spine i.e., ipsilateral and/or contralateral iliac crest. However, 0.9% sodium chloride (NaCl) Baxter or equivalent (9 mL) is injected into the osteoarthritic knee joint (Arm C, Study 1).
Participants will undergo a lipoaspiration. 40 mL of lipoaspirate (LA) will be collected from subcutaneous adipose tissue. LA will be processed using the Cervos LIPO-PRO™ kit and a centrifuge. Participants will also undergo a blood draw. About 30 mL of whole blood will be collected from the antecubital fossa. Whole blood will be processed using the Cervos KEYPRP kit and a centrifuge. After processing, 9 mL (or less) of LAM is injected first followed immediately by 2 mL (or less) of LP-PRP into the osteoarthritic knee joint (Arm B, Study 2).
Participants will undergo a lipoaspiration to collect 40 mL of LA and a blood draw to collect about 30 mL of whole blood. However, 0.9% of sodium chloride (NaCl) Baxter or equivalent is injected twice (9 mL + 2 mL) into the osteoarthritic knee joint (Arm D, Study 2).
