150 patients diagnosed with primary knee osteoarthritis will be enrolled by up to 3 centers.
The study includes 7 visits at the site center.
V-1 (eligibility assessment / screening visit):
- Collection of written informed consent
- Physical examination, including measurement of anthropometric parameters and vital signs (height, weight, diastolic / systolic pressure, heart rate)
- Diagnosed with radiologically confirmed primary osteoarthritis of the knee according to American College of Rheumatology criteria (i.e. one or more osteophytes and a measurable joint space on a plain radiograph taken within 3 months prior to screening).
- Blood tests: glycemia, creatinine, complete blood count with formula, ALT, AST, ALP, calcium, potassium, sodium, C reactive protein, total bilirubin. Urinalysis.
- Advice on daily diary writing to collect the number of concomitant medication before V0
- Recording of adverse events and concomitant therapies in the daily diary
V0 (confirmation of possession of selection criteria):
- Physical examination, including measurement of anthropometric parameters and vital signs (height, weight, diastolic / systolic pressure, heart rate)
- Randomization 1:1 to Investigational device or active comparator Jonexa
- Intra-articular administration
- Observation of the patient for 30 minutes post injection
- Compliance with daily diary completion
- Administration of questionnaires: WOMAC Pain and Function, SF-36 and global symptom relief questionnaire (CGI- I).
- Recording of any changes in concomitant therapies and any adverse events.
V1(Day 3): safety visit (3 days after V0)
- Objective examination, including measurement of vital parameters (weight, diastolic/systolic blood pressure, heart rate).
- Safety evaluation and AEs recording and Concomitant Therapies
- Checking the completion of the daily diary.
V2 (V2, week 2 ± 2 days) follow-up visit:
- Objective examination, including measurement of vital parameters (weight, diastolic/systolic blood pressure, heart rate).
- Checking the completion of the daily diary.
- Administration of the global symptom relief questionnaire (CGI- I).
- Administration of the WOMAC Pain questionnaire.
- Recording of adverse events and concomitant therapies.
- Instruction to fill in the daily diary via web app (smart phone) to report the use of all concomitant therapies. If patient is not able to use web app, a paper copy will be given.
V3 (V3, week 4 ± 2 days): follow-up visit:
- Objective examination, including measurement of vital parameters (weight, diastolic/systolic blood pressure, heart rate).
- Checking the completion of the daily diary.
- Administration of the global symptom relief questionnaire (CGI- I).
- Questionnaire administration: WOMAC Pain and Function, SF-36.
- Recording of adverse events and concomitant therapies.
- Instruction to fill in the daily diary via web app (smart phone) to report the use of all concomitant therapies. If patient is not able to use web app, a paper copy will be given.
V4 (V4, week 12 ± 2 days) follow-up visit:
- Physical examination, including measurement of anthropometric parameters and vital signs (height, weight, diastolic / systolic pressure, heart rate)
- Check of daily diary
- Administration of the global symptom relief questionnaire (CGI- I).
- Questionnaire administration: WOMAC Pain and Function, SF-36.
- Recording of adverse events and concomitant therapies.
- Instruction to fill in the daily diary via web app (smart phone) to report the use of all concomitant therapies. If patient is not able to use web app, a paper copy will be given.
V5 (V5, week 24 ± 3 days) end-of-study or premature discontinuation visit:
- Objective examination, including measurement of vital parameters
- Blood tests: blood glucose, creatinine, blood count with formula,AST, ALP, calcemia, potassium, sodium, C-reactive protein, total bilirubin. Urine examination.
