Boston, Massachusetts 01843


Purpose:

This is a clinical study in two phases. The first phase compares the effect of an ointment containing parathyroid hormone (PTH) with the effect of a placebo ointment (inactive ointment without PTH) on psoriasis lesions. Neither the study participants nor the researchers will know who is receiving PTH ointment and who is receiving placebo until the end of this first study phase. The second phase is a study of the PTH ointment on large areas of psoriasis to find out how long the effects last.


Study summary:

Patients with active plaque psoriasis will be withdrawn from systemic and topical medications.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.


Criteria:

Inclusion Criteria: - Active plaque psoriasis at least 10 percent BSA (body surface area) - Age 18-70 Exclusion Criteria: - Abnormalities of calcium metabolism
