ROSA: Treatment of Knee Osteoarthritis With PAAG-OA
Study Details
Study Description
Brief Summary
This is a multi-center, randomized, double-blind clinical investigation to compare the effectiveness of intra-articular polyacrylamide hydrogel (PAAG-OA) and a hyaluronic acid, Synvisc-One to induce symptomatic benefit in subjects with knee osteoarthritis.

Outcome Measures
Primary Outcome Measures
- Comparing one injection of PAAG-OA with one injection of Synvisc-One on pain over 6 months in subjects with knee osteoarthritis [6 months]
Change in WOMAC (WOMAC Osteoarthritis Index) pain subscale. Pain is reported in each of five response categories (0=none, 4=extreme)
Secondary Outcome Measures
- WOMAC [1, 3, 6 and 12 months]
WOMAC (WOMAC Osteoarthritis Index) self reported pain, stiffness and physical function, categories (0=none, 4=extreme)
- PGA (Patient Global Assessment) [1, 3, 6 and 12 months]
PGA reported on a 10 cm Visual Analogue Scale
- EQ-5D-5L, QoL [1, 3, 6 and 12 months]
EQ-5D-5L, Quality of Life, comprised of descriptive system where each dimension has 5 levels (ranging from no problems to extreme problems) and a 20 cm Visual Analogue Scale (0 = worst health and 100 = best health)
- OMERACT-OARSI responder criteria [1, 3, 6 and 12 months]
Per the OMERACT-OARSI criteria, a subject is classified as a positive responder if at least one (1) of the following two (2) conditions is observed at the post-baseline assessment: In either pain (WOMAC pain subscale) or function (WOMAC function subscale), a high improvement in the subscale, where high improvement in a subscale is achieved if there is both a > 50% improvement from Baseline and an absolute change from Baseline of > 20 normalised units (0-100 scale) OR Improvement in at least two (2) of the following three (3): Improvement in pain (WOMAC pain subscale) defined as > 20% improvement from Baseline and an absolute change from Baseline of > 10 (0-100 scale) Improvement in function (WOMAC function subscale) defined as > 20% improvement from Baseline and an absolute change from Baseline of > 10 (0-100 scale) Improvement in PGA defined as > 20% improvement from Baseline and an absolute change from Baseline of > 10 mm (0-100 sc
