Charite University, Berlin, Germany
Previous Biogen studies have provided experience with the tolerability, immunogenicity, and efficacy of a single and multiple 12-week courses of therapy of alefacept. At this stage, experience in larger studies, as well as the FDA-approved labeling, is confined to treatment courses of 12 weeks. The purpose of the present study is to offer an extended course of therapy with alefacept.

Condition Intervention Phase

Further study details as provided by Charite University, Berlin, Germany:

Primary Outcome Measures:
  • Safety of an extended courses of alefacept when administered to subjects with chronic plaque psoriasis. Safety parameters: Physical examinations; vital signs; infections; blood test: lymphocyte subset analysis (CD4+); and adverse events. [ Time Frame: 12 + 4 weeks ]

Secondary Outcome Measures:
  • Efficacy of an extended course of alefacept when administered to subjects with chronic plaque psoriasis: Time to requirement of additional systemic therapies, Psoriasis Area and Severity Index (PASI); Physician Global Assessment (PGA). [ Time Frame: 12 + 4 weeks ]

Enrollment: 20
Study Start Date: February 2004
Study Completion Date: December 2005
Primary Completion Date: December 2005 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Alefacept Drug: Alefacept
Alefacept=LFA-3/IgG1 fusion protein, once weekly, 15mg i.m.
Other Name: LFA-3/IgG1 fusion protein

Detailed Description:
Twenty statistically matched patients (15 males, 5 females, aged between 28 and 70 years, median 50 years) with moderate to severe psoriasis (PASI: 7-36) were included in this study. They were treated with 15 mg alefacept i.m. weekly. Peripheral blood was taken prior to first alefacept application and then weekly until week five and thereafter every second week, until the end of treatment at week 13. At the same time points severity of disease and thereby possible reduction of symptoms was evaluated applying the PASI. Investigators analysing the samples were blinded to the outcome of the study. The protocol concerning human subjects was approved by the ethics commission of the Charité University Medicine Berlin Campus Mitte, Germany .
