- W2921092016 abstract "Osteoarthritis (OA) is a major public health problem characterized by joint pain, fatigue, functional limitation and decreased quality of life of the patient, which results in increased use of healthcare services and high economical costs. A promising novel bioactive cell-free formulation (BIOF2) for cartilage regeneration has recently been tested in pre-clinical and clinical trials, and has demonstrated a success rate similar to that of total joint arthroplasty for the treatment of severe knee OA. The present study evaluated the efficacy of treatment with BIOF2, by including it within a conservative regimen of 'usual medical care' of knee OA, and whether its efficacy was affected in subgroups of patients presenting with comorbidities that exacerbate OA. A prospective, randomized, 2-arm parallel group phase III clinical trial was conducted, which included 105 patients in the 'usual medical care' group (paracetamol/NSAIDs and general care provided by the family physician) and 107 patients in the BIOF2 group (usual medical care + intra-articular BIOF2 application at 0, 1 and 2 months). Two aspects were evaluated at 0, 6 and 12 months: i) Minimal clinically important improvement (MCII), based on 30% improvement of pain from the baseline; and ii) the Patient Acceptable Symptom State (PASS), a questionnaire that determines patient well-being thresholds for articular pain and function. Adverse effects and regular NSAID use were registered. At 12 months, BIOF-2 treatment produced MCII in 70% of the patients and >50% achieved PASS. Excluding the patients with class 2 obesity or malalignment conditions (genu varum or genu valgum >20 degrees), the experimental treatment produced MCII and PASS in 100 and 92% of patients, respectively, compared with 25 and 8% in the group of usual medical care (P<0.001). No patient with malalignment and treatment with BIOF2 achieved PASS. Notably, there were no serious adverse effects. To conclude, BIOF2 is a safe therapeutic alternative that is easy to implement together with usual medical care for knee OA.
