Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Safety and tolerability	Primary objective of this study is to assess the safety and tolerability of EVI-01 following single intraarticular administration in the knee joint, assessed with adverse events monitoring throughout the follow up duration of six months.	6 months
Secondary	Change in patient-reported pain intensity	Change in patient-reported pain intensity at Days 1 to 7 compared to baseline will be assess using a 0-100 mm Visual Analogue Scale (VAS), in which 0 means ''no pain at all'' and 100 means ''the worst possible pain''.	7 days
Secondary	Change in WOMAC index	The Western Ontario and McMaster Universities Arthritis Index (WOMAC) consists of a total of 24 questions divided in 5 questions related to pain, 2 questions related to stiffness and 17 questions related to difficulties in performing activities of daily living in relation to physical function. Each question refers to a 0-100 mm Visual Analogue Scale (VAS) in which 0 means ''no pain at all'' and 100 means ''the worst possible pain''. Change in WOMAC pain, stiffness, function and total score will be assess using WOMAC index at Day 7, Day 14, Day 30, Day 90 and Day 180 compared to baseline	6 months
Secondary	Patient satisfaction for the overall treatment effect	Measurements of relief satisfaction by the patient will be assess using a 7 points Likert scale at Day 180. A 7 point Likert scale offers 7 different answer options related to an agreement that would be distinct enough for the respondents (Very good, Good, Fairly good, Same as before, Fairly bad, Bad, Very bad).	6 months
Secondary	Physician satisfaction for the overall treatment effect	Measurements of relief satisfaction by the physician will be assess using a 7 points Likert scale at Day 180. A 7 point Likert scale offers 7 different answer options related to an agreement that would be distinct enough for the respondents (Very good, Good, Fairly good, Same as before, Fairly bad, Bad, Very bad).	6 months
