NCT01289626

Brief Summary

The research question and primary aim is to determine if lanthanum carbonate is effective in treating calciphylaxis by measurement of complete or partial remission of skin lesions. Secondary endpoints will be measured to determine if lanthanum carbonate can lower calcium-phosphorus product levels, intact PTH and mortality. Albumin levels will be measured as a marker of nutritional status and inflammation.

Outcome Measures

Primary Outcomes (1)

  • Remission of calciphylaxis skin lesions

    The primary aim of this study will be the complete or partial remission of calciphylaxis skin lesions after 12 weeks of therapy as defined by the clinician.

    12 weeks

Secondary Outcomes (4)

  • Measurement of phosphorus

    12 weeks

  • Intact PTH

    12 weeks

  • Albumin

    12 weeks

  • Quality of life

    12 weeks

Interventions

FOSRENOL® will be administered orally in a dose of 1500- 3750 mg daily in divided doses with meals. Dose escalation will be utilized to a target dose of 3750 mg daily or as designated by clinician over a 4-week period from start of study. The drug will be administered for 12 weeks.
