Investigating the Use of Prolia (Denosumab) in the Treatment of Acute Charcot Neuroarthropathy

Completed · Phase 3

Conditions studied: Charcot Joint of Foot

In brief

Charcot neuroarthropathy (CN) is a debilitating disease primarily affecting poorly controlled diabetic patients with peripheral neuropathy. The consequences of CN include ulcerations of the foot and ankle, osteomyelitis, and severe musculoskeletal deformity. These consequences frequently lead to below-knee amputation of the affected limb. Currently treatment options are limited, and no pharmaceutical treatment has been efficacious in the medical literature. The purpose of this pilot study is to investigate the potential of the medication denosumab for acute stage Charcot neuroarthropathy.
