Study of Topical Calcitriol or Oral Calcitriol in Patients With Psoriasis

Overview[ - collapse ][ - ]

Purpose OBJECTIVES: I. Evaluate the long term safety and efficacy of orally administered calcitriol in patients with at least 5% of their body covered with psoriasis. II. Evaluate the long term safety and efficacy of topically administered calcitriol in patients with at least 5% of their body covered with psoriasis. III. Compare the topical calcitriol treatment to the oral calcitriol treatment in these patients.

Brief Summary
OBJECTIVES: I. Evaluate the long term safety and efficacy of orally administered calcitriol
in patients with at least 5% of their body covered with psoriasis.

II. Evaluate the long term safety and efficacy of topically administered calcitriol in
patients with at least 5% of their body covered with psoriasis.

III. Compare the topical calcitriol treatment to the oral calcitriol treatment in these
patients.
Detailed Description
PROTOCOL OUTLINE: This is a part placebo-controlled (arm I) study. Patients either apply
topical petrolatum (Vaseline) with calcitriol (vitamin D3) on a psoriatic lesion daily and
petrolatum only on an other similar lesion daily to serve as a control (arm I) or receive
oral calcitriol nightly (arm II).

Arm I patients continue treatment for at least 2 months. At the end of 2 months of topical
treatment, one biopsy is taken of the lesion treated with calcitriol, one biopsy of the
lesion treated with petrolatum alone, and one biopsy of skin unaffected by psoriasis.
Lesions are also photographed prior to therapy, 2-4 weeks during therapy for the first two
months, then once every 1-3 months, and then once at end of treatment.

Arm II patients increase dosage of oral calcitriol every 2 weeks up to a maximum dosage
daily in the absence of adverse effects (high urinary calcium or serum calcium levels).
Patients continue treatment for at least 1 month. Lesions are photographed prior to therapy,
2-4 weeks during therapy, and then once at end of treatment.
