Brief Summary:
The aim of the present trial is to assess the efficacy of treatment of acute Charcot foot in diabetes patients with Prolia® on clinical relevant Outcomes in a randomized, double blind, placebo-controlled trial.

Condition or disease Intervention/treatment Phase
Charcot Foot Diabetes Mellitus Drug: Denosumab Injection Phase 3

Detailed Description:

After giving informed consent and being enrolled, patients will be randomized to one of two group given either Denosumab treatment or injection with placebo. The patients will then undergo a 52 week follow up with regular controls to asses if clinical signs of Charcot is in remission, which will be verified using relevant radiological modalities. Upon final visit the patients will be examined using radiology, blood samples, biothesiometry and objective examinations, following up on the same examinations being made upon inclusion.

Primary outcome will be time until full remission of the Charcot foot defined as clinical healing (The acute Charcot foot is clinically healed when the temperature difference at the site maximum temperature on the affected Charcot foot is < 2 degrees Celsius compared to the similar site on the contra-lateral foot, measured using an infrared thermometer, and edema and redness of the skin has subsided) followed up by radiological signs of healing.

Drug Information available for: Denosumab

Arm Intervention/treatment
Experimental: Denosumab treated group
Participants will receive a 60 mg subcutaneous injection of Prolia upon randomization and on week 28 after the first injection provided remission of the Charcot foot has not been achieved by then
Drug: Denosumab Injection
Injections made subcutaneously per standard description

Placebo Comparator: Placebo treated group
Participants will receive an injection of placebo produced by the same provider as the prolia drug of equivalent volume at the same time points as the treated group
Drug: Denosumab Injection
Injections made subcutaneously per standard description

Primary Outcome Measures :
  1. Time until remission [ Time Frame: 52 weeks ]
    Time from first injection of IP until the time point where the acute Charcot foot is clinically healed/in remission, ie. the temperature difference at the site maximum temperature on the affected Charcot foot is < 2 degrees Celsius compared to the similar site on the contra-lateral foot, measured using an infrared thermometer, and edema and redness of the skin has subsided - at two subsequent visits 4 weeks apart. The off-loading regime will be continued until the second visit. The first of the two visits is the timepoint of healing of the acute Charcot foot.

Secondary Outcome Measures :
  1. Fraction of clinical healed participants at each study visit. [ Time Frame: 52 weeks ]
  2. Fraction of healing on X-rays and MRI (or PET/CT or Scintigram) at the time of clinical healing and at the End of trial. [ Time Frame: 52 weeks ]
  3. Number of relapses (defined as need for/prescription of off- loading with cast of the Charcot foot again) [ Time Frame: 52 weeks ]
  4. Time without relapse (the time from clinical healing/remission to the relapse or to End of Trial at 12 months). [ Time Frame: 52 weeks ]
  5. Number of patients with development of complications to the acute Charcot foot, as well as number of development of foot ulcer, deformity, need for special footwear or surgery and fractures of bones in the foot, respectively. [ Time Frame: 52 weeks ]
  6. Changes in BMD (lumbar spine, hip) [ Time Frame: 52 weeks ]
  7. Changes in markers of bone turnover (CTX and P1NP) [ Time Frame: 52 weeks ]
  8. Changes in markers of glycemic control (HbA1c) [ Time Frame: 52 weeks ]
  9. Incidence of Adverse Events and Serious Adverse Events [ Time Frame: 52 weeks ]
