28 Jun 2017 --- Bioiberica’s Chondroitin sulfate CS b-Bioactive delays osteoarthritis progression and is as effective as the anti-inflammatory drug celecoxib at improving the disease’s symptoms. These are the main conclusions of a clinical essay presented by Professor Jean Pierre Pelletier at the Annual European Congress of Rheumatology, held in Madrid. Conducted by Bioiberica, the MOSAIC clinical essay (a 24-month study on structural changes in knee osteoarthritis assessed by MRI with Chondroitin sulfate) is a multicenter, randomized, double-blind, controlled and comparative study, carried out in five medical centers in Quebec (Canada).
