• Study Design: SINGLE_GROUP

Primary Outcome Measures

Name	Time	Method
Clinical performance of AI500™ SINGLE DOSE GEL in improving knee function after 1 week	1 Week	To evaluate the clinical performance of AI500™ SINGLE DOSE GEL in improving knee function after 1 week of treatment, change from baseline (V0) to week 1 (V3) in Western Ontario and McMasters Universities Osteoarthritis Index (WOMAC) Physical Function score will be evaluated.; The test questions are scored on a scale of 0-4, which correspond to: None (0), Mild (1), Moderate (2), Severe (3), and Extreme (4). The scores for each subscale are summed up, with a possible score range of 0-20 for Pain, 0-8 for Stiffness, and 0-68 for Physical Function.

Secondary Outcome Measures

Name	Time	Method
Clinical performance of AI500™ SINGLE DOSE GEL in improving knee function after 48 hours	2 days	To evaluate the clinical performance of AI500™ SINGLE DOSE GEL in improving knee function after 48 hours of treatment, change from baseline to 48 hours (V2) in WOMAC Physical Function score will be evaluated.; The test questions are scored on a scale of 0-4, which correspond to: None (0), Mild (1), Moderate (2), Severe (3), and Extreme (4). The scores for each subscale are summed up, with a possible score range of 0-20 for Pain, 0-8 for Stiffness, and 0-68 for Physical Function.
Clinical performance of AI500™ SINGLE DOSE GEL in alleviating pain after 24h and 48h of treatment.	2 days	To evaluate the clinical performance of AI500™ SINGLE DOSE GEL in alleviating pain after 24h and 48h of treatment, change in NRS between V0 and V1, and between V0 and V2 will be analysed.; NRS Score has a range of 0-10 for pain; 0=no pain; 10=max pain.
Safety and Tolerability of AI500™ SINGLE DOSE GEL	1 week	To evaluate the safety and tolerability of AI500™ SINGLE DOSE GEL, physical examination and adverse events (AEs), including of the relationship of the AE to the IP (e.g., local allergic reaction), will be assessed through the study.; Safety and tolerability of the AI500™ will be evaluated through a the completion of a specific questionnaire by the patient, the five-points Likert scale in which 1 means Strongly disagree with the assertion and 5 means Strongly agree
