About the study

The purpose of the study is to find out if the investigational treatment named QUC398 has beneficial effects on osteoarthritis knee pain and knee cartilage, and if it is safe and well tolerated.

3. Radiographic medial joint space width (mJSW) of 2 to 4 mm in men or 1.5 to 3.5 mm in women measured at the X=0.225 fixed point location within the medial tibio-femoral compartment of the target knee at Screening 1
4. Symptomatic OA with moderate to severe pain (corresponding to Pain NRS ≥ 5 to ≤ 9) in the target knee for the majority of days in the last 3 months prior to Screening 1, as per participant's judgement
5. Symptomatic OA with moderate to severe pain (corresponding to Pain NRS ≥ 5 to ≤ 9) in the target knee at Screening 1 and 2 . Moderate to severe OA pain (corresponding to Pain NRS ≥5 to ≤9) in the target knee during the last 7 days prior to Screening 3, confirmed by: Completed pain diary for at least 6 of the last 7 days prior to Screening 3, AND Diary reported Pain NRS ≥5 to ≤9 for at least 6 of the last 7 days prior to Screening 3
6. KOOS pain subscale ≤ 60 in the target knee at Screening 1, Screening 2, and Screening 3

2. Symptomatic, patello-femoral pain in the target knee as per investigator's examination at Screening 1
3. Severe malalignment > 7.5º in the target knee (either varus or valgus), measured using standardized knee X-ray at Screening 1
4. Patient unable or unwilling to undergo MRI or presenting absolute contraindications to MRI
