- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: DOUBLE
- Phase: PHASE2
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion criteria :~* Men or women 40 to 80 years of age.~* Diagnosis of primary knee osteoarthritis (OA), based upon the following:~* Fulfilling the American College of Rheumatology Clinical and Radiographic criteria for OA (at least knee pain and osteophytes), with~* X-ray evidence within the last 6 months for Kellgren and Lawrence classification II to IV.~* Western Ontario and McMaster Universities Arthritis Index (WOMAC) A1 Pain subscore (walking pain) over the last 48 hours ≥40 and ≤90 on VAS 0-100 in the target knee at screening with or without medication, and ≤30 on Visual Analogue Scale (VAS) 0-100 in the contralateral knee at screening with or without medication.~* WOMAC A1 pain subscore (walking pain) between 50 and 90 using the VAS 0-100, corresponding to moderate to severe pain in the target knee at baseline (from eDiary, average of at least 3 days in the time window between Day-5 and Day-1).~* Symptomatic for more than 6 months (if both symptomatic knees, at least for the most painful knee that will receive the study drug).~* Having given written informed consent prior to any procedure related to the study.~* Ambulatory with an active lifestyle and in good general health. (Assistive devices were allowed if used throughout a period of 3 months or more prior to screening, on the condition that they continue to be used throughout the study).~* A male who is sexually active must use a condom as part of a method of highly effective contraception (eg, condom + spermicide, and an additional contraceptive method used by the partner) during sexual intercourse with a women of childbearing potential for the duration of the study period up to the end-of-study visit and should not father a child in this period. Male patients also have to agree not to donate sperm for the duration of the study until the end-of-study visit.~Exclusion criteria:~* Women of childbearing potential.~* Pregnant or breastfeeding women.~* Any uncontrolled, chronic condition or laboratory finding which, in the opinion of the Investigator, could potentially put the patient at increased risk.~* Patients with clinically significant or uncontrolled hepatic, gastrointestinal, cardiovascular, respiratory, neurological (including diabetic neuropathy), psychiatric, hematological, renal, or dermatological disease, or any other medical condition, such as symptomatic peripheral vascular disease of the study leg (prior or current), clinically significant venous or lymphatic stasis present in the study leg, that might interfere with the evaluation of investigational medicinal product (IMP) according to Investigator's medical judgment.~* Chondrocalcinosis.~* Fibromyalgia.~* Moderately severe or severe depression as indicated by Patient Health Questionnaire-9 (PHQ-9) total score at screening visit.~* Severe anxiety as indicated by Generalized Anxiety Disorder (GAD-7) score at screening visit.~* History or presence of drug or alcohol abuse (alcohol consumption \>40 grams per day).~* Any patient who, in the judgment of the Investigator, is likely to be noncompliant during the study, or unable to cooperate because of a language problem or poor mental development, or unable to use an electronic diary daily.~* Abnormal coagulation parameters: outside the range international normalized ratio (INR) 0.85-1.15, activated partial thromboplastin time \>33 seconds, platelets \<140 x 10\^9/L.~* Moderate to severe renal impairment.~* Underlying hepatobiliary disease and/or alanine aminotransferase (ALT) \>2 x upper limit of normal (ULN).~* High sensitivity C-reactive protein (hsCRP) \>2 x ULN.~* Hemoglobin \<10 g/dL, white blood cell count (WBC) \<3 x 10\^9/L.~* Positive result on any of the following tests: hepatitis B surface antigen (HBsAg), anti-hepatitis C virus (anti-HCV) antibodies, anti-human immunodeficiency virus 1 and 2 antibodies (anti-HIV1 and anti HIV2 Ab).~* Secondary OA. -Ipsilateral hip OA.-~* History of osteonecrosis and/or rapidly progressive OA (RPOA).~* Intraarticular injection within 3 months prior to inclusion.~* Unable to be maintained for at least 2 weeks prior to entry into study on paracetamol (no non-steroidal anti-inflammatory drug \[NSAID\] use during the 12 weeks of the study; after the end-of-study visit \[Day 84 ± 7\] patients may be given an NSAID if necessary to provide better control of OA symptoms).~* Any IMP within 3 months prior to the study.~* Any knee magnetic resonance imaging (MRI) contraindication.~* Patients at risk of developing a RPOA with pre-existing findings on MRI of the target knee at baseline.~* Patients with pain DETECT questionnaire (PD-Q) score \>18.~The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial.
