Study Overview
Brief Summary
This is a double-blinded, placebo-controlled, randomized trial to assess the efficacy of oral solution of hyaluronic acid mixture (A+ HA(tm)). During 8 weeks treatment period, there were three follow-up visits requested (Week 2, Week 4 and Week 8).
Detailed Description
Subjects were initially screened at the Randomization/Baseline Visit (Week 0). Eligible subjects were randomized at the same visit into treatment period, and received the assigned treatment in a double-blind fashion for 8 weeks. Efficacy was measured by the several questionnaire including Knee injury and Osteoarthritis (KOOS), the Short Form-36 (SF-36) and Pittsburgh Sleep Quality Index (CPSQI) for each visit. Incidences of adverse events (AEs) were monitored for each subject once the subject had received 1 dose of study medication; the incidence of serious AEs (SAEs) were monitored for each subject once the subject had signed the informed consent through to the End-of-Study or ET Visit. Vital signs were measured at baseline and End-of-Study or ET Visit.
