Current Primary Outcome: Number of patients with 30% improvement in pain severity [ Time Frame: randomization to 3 weeks ]
Original Primary Outcome: Same as current
Current Secondary Outcome:
- Secondary Endpoint-a: Number of patients with stabilization or improvement in calciphylaxis skin lesions. [ Time Frame: randomization to 3 weeks ]Proportion of patients who achieve improvement or stabilization (i.e., not worsening) of skin lesions.
- Secondary Endpoint-b: Occurence of surgical debridement of skin lesions and/or amputation. [ Time Frame: during week 3 ]Occurence of surgical debridement of skin lesions and/or amputation.
- Secondary Endpoint-c: Occurrence of surgical debridement of skin lesions and/or amputation. [ Time Frame: randomization to 3 weeks ]Occurrence of surgical debridement of skin lesions and/or amputation.
- Secondary Endpoint-d: Time to achieve ≥ 30% improvement in pain severity [ Time Frame: randomization to 3 weeks ]Time in days when a patient achieves a ≥ 30% improvement based upon pain intensity score (modified BPI/SF).
Original Secondary Outcome: Same as current
