| Main Objective: The objective of this study is to assess the safety and efficacy of JTA-004® single intra-articular administration in patients suffering from symptomatic osteoarthritis of the knee at the end of the study period (at Month 6). Safety: At each follow-up visit, patients will be assessed for the occurrence of any (serious) adverse events using patient open non-directive questionnaire, physical examination (including vital signs), and laboratory measurements. The safety analyses will be based on incidence evaluation of treatment emergent adverse events by preferred term and body system. Laboratory measurements will be compared to the normal laboratory ranges and to laboratory measurements obtained at Baseline Visit. Efficacy: Primary study objectives are (i) the selection of the best JTA-004® strength and (ii) the superiority assessment of the best JTA-004® strength efficacy to the reference or (iii) stop the trial at interim analysis for futility.;Secondary Objective: The secondary efficacy endpoints are: -WOMAC® VA3.1 pain subscale (WOMAC® subscale A) at Month 3 -WOMAC® VA3.1 total score over the time ;Primary end point(s): The WOMAC® VA 3.1 pain subscale scoring at baseline and subsequent assessment time points is the major efficacy criteria;Timepoint(s) of evaluation of this end point: Safety and efficacy endpoints will be evaluated at each of the 3 follow-up visits during the 6-month follow-up period (notably at 2 weeks, 3 months and 6 months after study drug administration). For selection of best JTA-004® strength, by comparing the different JTA-004® strengths to the reference with respect to the WOMAC® VA3.1 pain subscale score (mean differences between baseline and Month 3) For superiority assessment, by comparing the best JTA-004 strength and reference on the mean differences in WOMAC® VA3.1 pain subscale score between baseline and Month 6, assuming a mean between group difference of 7 mm with a standard deviation of 10 mm. | — |
