Brief Summary:
The primary objectives are to assess the efficacy, safety, and tolerability of SNF472 compared to placebo when added to background care for the treatment of calciphylaxis (CUA).

Condition or disease Intervention/treatment Phase
Calciphylaxis Calcific Uremic Arteriolopathy Drug: Experimental: SNF472 Drug: Placebo Comparator: Placebo Drug: Experimatenl SNF472 (Open-label) Phase 3

Detailed Description:
The formation and growth of calcified deposits in arterioles and other small blood vessels appears to be fundamental to the development of CUA especially in end stage renal disease patients. This phase 3 double-blind, randomized, placebo-controlled study is designed to assess the effect of SNF472 when added to background care to improve wound healing, as evaluated using Bates-Jensen Wound Assessment Tool (BWAT) scoring and pain as reported by the subject using a VAS scale. The study consists of a double-blind, randomized, placebo controlled period of 12 weeks followed by an open-label period of 12 weeks.. .

Arm Intervention/treatment
Experimental: SNF472 (Double-Blind Period)
Dose: 7 mg/kg SNF472 diluted in 100 mL physiological saline.
Drug: Experimental: SNF472
Administered 3 times weekly by intravenous infusion through the hemodialysis machine in conjunction with the subject's hemodialysis sessions for 12 weeks

Placebo Comparator: Placebo (Double-Blind Period)
Matching placebo (saline) diluted in 100 mL physiological saline.
Drug: Placebo Comparator: Placebo
Administered 3 times weekly by intravenous infusion through the hemodialysis machine in conjunction with the subject's hemodialysis sessions fo 12 weeks
Other Name: Saline

Experimental: SNF472 (Open-Label)
Dose: 7 mg/kg SNF472 diluted in 100 mL physiological saline.
Drug: Experimatenl SNF472 (Open-label)
Administered 3 times weekly by intravenous infusion through the hemodialysis machine in conjunction with the subject's hemodialysis sessions for 12 weeks




Primary Outcome Measures :
  1. Change in the BWAT-CUA score for the primary lesion [ Time Frame: Basline to week 12 ]
    The Bates Jensen Wound Assessment Tool (BWAT) CUA score ranges from a minimum score of 8 (best) to a maximum score of 40 (worst)

  2. Change in Pain VAS score [ Time Frame: Baseline to Week 12 ]
    The Pain Visual Analog Scale (VAS) score ranges from a minimum score of 0 (no pain) to 100 (worst possible pain)


Secondary Outcome Measures :
  1. Change in the Wound-QoL score [ Time Frame: Basline to Week 12 ]
    The Wound Quality of Life scale is a validated self-assessment tool that has been shown to be feasible for assessing health-related quality of life in patients with chronic wounds. Lower scores are associated with a better quality of life as reported by the patient.

  2. Change in the BWAT total score for the primary lesion [ Time Frame: Baseline to Week 12 ]
    The Bates Jensen Wound Assessment Tool (BWAT) score ranges from a minimum score of 9 (best) to a maximum score of 65 (worst) score

  3. Qualitative wound image evaluation for the primary lesion [ Time Frame: Baseline to Week 12 ]
  4. Rate of change in opioid use as measured in morphine milligram equivalents (MME) [ Time Frame: Baseline to Week 12 ]

  • Significant noncompliance with dialysis
  • History of active malignancy within the last year with the exception of localized basal cell or squamous cell carcinoma
