Study 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.

Read the 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.

Inclusion criteria

  • Age 18-80 years
  • Type 1 or type 2 diabetes (diagnosed diabetes for more than 3 months)
  • Diagnosed with acute Charcot foot defined as a unilateral red, swollen and warm foot, with a difference of skin temperature of more than 2 °C compared with the unaffected foot and with sign of Charcot on either x-rays of the foot, MRI, bone scintigram or PET/CT.
  • Peripheral neuropathy: Previously diagnosed and/or biothesiometri: > 25 V or lack of sensation of 10 grams monofilament on 1. toe at the acute Charcot foot.

Exclusion criteria

Exclusion Criteria:

  • Duration of the acute Charcot foot for more than 3 months (at the screening visit).
  • Existing foot ulcer on the affected foot

  • Infection (cellulitis or osteomyelitis) of the affected foot (clinically and/or radiologically proven)
  • Previous midfoot or proximal to mid foot amputation of the affected foot
  • Hypocalcemia (Serum Calcium \<2.1 mmol/L or Calcium ion \< 1.12 mmol/L)
  • Vitamin D deficiency (Serum 25-hydroxyvitamin D \< 50 nmol/L)

  • Active or chronic liver disease *Chronic liver disease is defined as clinical history of decompensated chronic liver disease (ascites, encephalopathy or variceal bleeding) *Acute Liver disease is defined as an INR of > 1.5 (in the absence of the use of Warfarin) and AST and ALT > 2 x ULN

    Drug: Denosumab Injection

  • Placebo comparator
    Placebo treated group

    Participants will receive an injection of placebo (saline) instead of Prolia

    Drug: Denosumab Injection

What researchers measure

Primary outcomes

  1. Time until remission

    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.

    Time frame: 52 weeks

Secondary outcomes

  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
