About this study
Official title: A Pilot Open-Label Study to Evaluate the Safety and Observe the Effectiveness of 16 Weeks of Alefacept in Palmar Plantar Pustulosis (IST 92)
The purpose of this study is to determine if Alefacept is effective in the treatment of palmar plantar pustulosis.
Read the detailed description
Palmar plantar pustulosis is a chronic, disabling skin condition which is difficult to treat since it is often recalcitrant to current treatments and associated with high recurrence rates. This condition appears to be a T lymphocyte mediated condition and is thought by some to be a subtype of psoriasis. Alefacept affects T cell activation and induces apoptosis of memory T cells. It has been shown to be efficacious in the treatment of psoriasis vulgaris and may be associated with prolonged remissions. There is extremely limited experience with use of Alefacept in Palmar Plantar Pustulosis. This pilot trial should provide additional information concerning its use for this indication.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Alefacept in people with Psoriasis and Palmoplantaris Pustulosis, run by The Guenther Dermatology Research Centre at 1 site in Canada.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 13 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 23 Nov 2006. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
percentage change in PPPASI from baseline. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Nov 2006; AzTrials last refreshed its copy on 8 Nov 2026.
