Study Overview
Brief Summary
The primary objective of the study is to evaluate the effect of fasinumab compared to placebo on peripheral nerves in participants with pain due to Osteoarthritis (OA) of the hip or knee.
The secondary objectives of the study are to:
- Evaluate the efficacy of fasinumab compared to placebo in participants with pain due to OA of the hip or knee
- Evaluate the safety and tolerability of fasinumab compared to placebo in participants with pain due to OA of the hip or knee
- Characterize the concentrations of fasinumab in serum in participants with pain due to OA of the hip or knee
- Evaluate the immunogenicity of fasinumab in participants with pain due to OA of the hip or knee.

Outcomes
Primary Outcomes
Change From Baseline in Peroneal Motor Nerve Action Potential Amplitude at Week 16
Time Frame: Baseline, Week 16
Peroneal motor nerve action potential amplitude was evaluated at ankle by electrical stimulation of the nerve and recorded the compound muscle action potential from surface electrodes overlying a muscle supplied by the nerve. Change from baseline in peroneal motor nerve action potential amplitude at Week 16 was reported.
Change From Baseline in Sural Sensory Nerve Action Potential Amplitude at Week 16
Time Frame: Baseline, Week 16
Sural sensory nerve action potential amplitude was evaluated by electrically stimulating sensory fibers and recorded the nerve action potential at a point further along that nerve. Change from baseline in sural sensory nerve action potential amplitude at Week 16 was reported.
Change From Baseline in Ulnar Sensory Nerve Conduction Velocity at Week 16
Time Frame: Baseline, Week 16
Ulnar sensory nerve conduction velocity was evaluated by electrically stimulating sensory fibers and recorded the nerve action potential at a point further along that nerve. Change from baseline in ulnar sensory nerve conduction velocity at Week 16 was reported.
Change From Baseline in Ulnar Sensory Nerve Action Potential Amplitude at Week 16
Time Frame: Baseline, Week 16
Ulnar sensory nerve action potential amplitude was evaluated by electrically stimulating sensory fibers and recorded the nerve action potential at a point further along that nerve. Change from baseline ulnar sensory nerve action potential amplitude at Week 16 was reported.
Change From Baseline in Peroneal Motor Nerve Conduction Velocity at Week 16
Time Frame: Baseline, Week 16
Peroneal motor nerve conduction velocity was evaluated by electrical stimulation of the nerve and recorded the compound muscle action potential from surface electrodes overlying a muscle supplied by the nerve. Change from baseline in peroneal motor nerve conduction velocity at Week 16 was reported.
