Treatment of Psoriasis With Parathyroid Hormone
|Study Design:||Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Primary Purpose: Treatment
|Official Title:||Evaluation of the Therapeutic Efficacy & Safety of Topical Administration of Parathyroid Hormone (PTH) in Psoriasis|
|Study Start Date:||January 2000|
|Estimated Study Completion Date:||April 2005|
Patients with active plaque psoriasis will be withdrawn from systemic and topical medications. After washout, we will select active psoriatic lesions of at least 25 square cm in size to receive either placebo ointment or a proprietary ointment containing PTH for 8 weeks. We will see the patients every 2 weeks. We will evaluate the lesions by examination and digital photography at each visit and measure parameters of calcium metabolism periodically during the 8 weeks.
At the conclusion of the 8 weeks, we will obtain punch biopsies from the treated lesions and from one lesion without treatment. If the patients elect, we will transition them into an open label trial with the PTH ointment including up to 1000 square cm of psoriatic lesions and monitor them for duration of effect and changes in parameters of calcium metabolism.
