Conditions
Keywords
Cyclosporine, chronic plaque psoriasis, intermittent therapy
Brief summary
The study will evaluate the efficacy of cyclosporine at 2, 5 mg/kg/day bid (i.e. bis in a day), when administered twice a week compared to continuous administration, in patients with chronic plaque psoriasis.
Interventions
Oral soft gelatin capsules of Cyclosporine 10 mg, 25 mg, 50 mg or 100 mg administered twice a week for 24 weeks at the dosage of 5 mg/Kg/day in two daily administrations
Oral soft gelatin capsules of placebo matching cyclosporine administered twice a week for 24 weeks in two daily administrations

| Number of Participants With Relapse Rate (Success or Failure), as Assessed by Psoriasis Area and Severity Index (PASI) Score | 24 weeks | PASI is an index used for assessing and grading the severity of psoriatic lesions and their response to therapy. The PASI produces a numeric score that can range from 0 (best) to 72 (worst), with the highest score representing complete erythroderma of severest degree. Relapse is considered a worsening of psoriasis associated to a PASI score \>75% of PASI score recorded before starting induction therapy with CsA (before study start). Each patient was considered as failure (relapse occurrence) if rate was \>= 75%. In all the other cases the patient was considered as success (no relapse). |

Outcome results
Number of Participants With Relapse Rate (Success or Failure), as Assessed by Psoriasis Area and Severity Index (PASI) Score
PASI is an index used for assessing and grading the severity of psoriatic lesions and their response to therapy. The PASI produces a numeric score that can range from 0 (best) to 72 (worst), with the highest score representing complete erythroderma of severest degree. Relapse is considered a worsening of psoriasis associated to a PASI score \>75% of PASI score recorded before starting induction therapy with CsA (before study start). Each patient was considered as failure (relapse occurrence) if rate was \>= 75%. In all the other cases the patient was considered as success (no relapse).
