Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Primary Objective:

To assess the efficacy of a single intraarticular dose of GZ389988 compared to placebo for relief of knee pain in patients with osteoarthritis (OA) of the knee.

Secondary Objectives:

To assess the safety and tolerability of a single intraarticular dose of GZ389988 in patients with painful OA of the knee.

To assess the pharmacokinetic parameters of a single intraarticular dose of GZ389988 in patients with painful OA of the knee.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Screening will be performed within 21 days of dosing. Following the single dose of study medication, the study period for each patient will be 84 ± 7 days up to the end-of-study visit.

Total duration for one patient will be up to 16 weeks (up to the end-of-study visit), not including the long-term observational safety follow-up phone call for 12 additional weeks.

The collection of primary endpoint data up to Week 4 for futility analysis is optional. Assuming a possible step-down in dose due to safety/tolerability reasons, the total expected maximum number of included patients could be increased up to a maximum of 182 patients.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Men or women 40 to 80 years of age.

* 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.

* 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.

* 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.
