Arm Intervention/treatment
Experimental: Efalizumab Drug: Efalizumab
Subjects will receive a conditioning dose of 0.7 milligram per kilogram (mg/kg) efalizumab subcutaneously on study Day 0 followed by 1.0 mg/kg efalizumab subcutaneously once a week for 23 weeks.
Other Name: Raptiva




Primary Outcome Measures :
  1. Percentage of Subjects With Physician's Global Assessment (PGA) Ratings of "Excellent" or "Cleared" at Week 24 [ Time Frame: Week 24 ]
    The PGA rating was used to assess the global response of all psoriatic lesions by comparing subject's present condition to baseline photographs or body diagrams. The response was classified as Cleared: 100% improvement of all clinical signs and symptoms compared to baseline; Excellent: 75% to 99% improvement of all signs and symptoms compared to baseline; Good: 50% to 74% improvement of signs and symptoms compared to baseline; Fair: 25% to 49% improvement of signs and symptoms compared to baseline; Slight: 1% to 24% improvement of signs and symptoms compared to baseline; Unchanged: Clinical signs and symptoms unchanged from baseline and Worse: Clinical signs and symptoms deteriorated from baseline.

  • Patients with the following may also be deemed to require systemic therapy in the judgement of the physician:
  • Severe psychosocial disability (in the judgement of the physician), or
  • Nail psoriasis, or
  • Scalp psoriasis, or
  • Palmar plantar psoriasis etc OR
  • B) Subjects who have completed the CLEAR study investigational medicinal product (IMP) 24011 (NCT00256139) and who wish to continue Raptiva (efalizumab) therapy.

  • Discontinuation of all biologic agents (other than Raptiva) 3 months prior to receiving first dose of study drug (Raptiva)
  • Discontinuation of Psoralen-ultraviolet light A (PUVA), Ultraviolet light B (UVB) treatment 28 days prior to commencement of receiving first dose of study drug.

  • Treatment regimens of b-blockers, Angiotensin-converting enzyme (ACE) inhibitors, antimalarial drugs, quinidine, interferon, or lithium stable for at least 28 days prior to first dose of study drug

Exclusion Criteria:

  • Guttate, erythrodermic, or pustular psoriasis as sole or predominant form of psoriasis
  • Active rebound of psoriasis during or following discontinuation of the previous Raptiva treatment( PASI >125% from baseline and/or new predominant morphology of psoriasis) when reason was adverse event or lack of efficacy of Raptiva. If it was due to another non drug reason (vaccination, or infection) then the patient can be included in this study.

  • Hepatic enzymes >3 times the upper limit of normal
  • History of active tuberculosis (TB) or currently undergoing treatment for TB within one year prior to study Day 0. Chest X-ray (within 3 months prior to Study Day 0) is required for high-risk patients. Patients with a positive chest X-ray will be excluded.
