Conditions

Erosive hand osteoarthritis (EHOA)

Brief summary

The primary endpoint is the difference in mean change of total erosion volume (mm3) of target joints (II, III, IV, V distal and proximal interphalangeal joints and II, III, IV, V metacarpal phalangeal joints) assessed with high resolution peripheral quantitative computed tomography (HRpQCT) using standardized approach between baseline (V1) and 12 months after baseline (V4)

Detailed description

The secondary endpoint will be the number and proportion of interphalangeal joints progressing from non‑erosive disease, defined as S/J phase at baseline, to erosive disease, defined as E phase at 48 weeks., The change from baseline to Month 12 in patient‑reported and functional outcomes, including AUSCAN (AUStralian CANadian Osteoarthritis Hand Index), FIHOA (Functional Index of Hand Osteoarthritis), and Pain VAS, reflecting pain, hand function, and disability from the patient perspective.
