Conditions

Knee osteoarthritis

Brief summary

A clodronate dose will be considered as effective when a ≥ 8.5 mm reduction in the VAS of knee pain will be observed at Week 7 vs. Placebo.

Detailed description

Mean changes in the VAS of knee pain observed at each other visit than Week 7 vs. Placebo and vs Baseline., Mean changes in the VAS of knee pain observed 120 minutes after IA injection at Baseline, Weeks 1, 2 and 3 vs predose assessment., Mean changes in the Lequesne Algo-functional Index at each visit vs Placebo and vs Baseline., Mean changes in the WOMAC Index at each visit vs Placebo and vs Baseline., Mean changes in the Range of Motion at each visit vs Placebo and vs Baseline., Use of rescue drug consumption (paracetamol) across the patients visits.
