Brief summary

The objective of the study was to assess the maintenance effect on scalp psoriasis of Clobex® Shampoo 0.05% when used twice weekly.

Detailed description

Psoriasis was a chronic disease that was affecting skin, the scalp and joints. Scalp psoriasis was very common and was having an important impact on people's life. Primary objective of scalp psoriasis treatments was to gain initial and rapid control of the disease process with a minimum of side-effects and improve patient quality of life. Still, one of the unmet needs of scalp psoriasis therapies was the maintenance of a long-term remission. For corticosteroids in particular, one of the drawbacks was the disease recurrences after cessation of the treatment. Therefore, the establishment of a modified corticosteroid dosing regimen that would allow remission with minimal side-effects was suitable. The purpose of this study was to assess how long a patient successfully maintained in a good condition after use of Clobex® shampoo only twice a week.

Recruitment details

The study was conducted at 12 sites in Canada from 29 September 2006 (first participant first visit) to 20 August 2007 (last participant last visit).

Pre-assignment details

A total of 288 participants were enrolled in initial phase of the study, of which 225 participants were eligible to enter maintenance phase after completion of initial phase. Out of 225 eligible participants, only 217 participants (as 8 participants withdrew consent) were randomized and received treatment in the maintenance phase either in Clobetasol Propionate Shampoo group or Vehicle group.

All Participants
In initial open-label phase, participants were applied Clobetasol Propionate shampoo 0.05% topically to the scalp once daily (twice a week) for 4 weeks (wherein weekly dose was not more than 50 grams \[50 milliliter\]). In maintenance double-blind phase, participants presented with a good efficacy (GSS \<= 2) in initial phase were randomized to apply Clobetasol Propionate Shampoo 0.05% (W/W) or Clobex® Vehicle Shampoo twice weekly up to 6 months (wherein weekly dose was not more than 50 grams \[50 milliliter\]). In case of relapse (i.e., GSS \> 2) participants were re-entered to 4-week daily treatment with Clobetasol Propionate Shampoo 0.05%. After this 4-week period of daily treatment, if GSS \<= 2, participants were re-entering the maintenance regimen (twice a week).

Maintenance Phase: Percentage of Participants With Number of Relapses Experienced

Number of relapses of participants were categorized as 0; zero relapse, 1; one relapse, 2; two relapse, 3; three relapse, 4; two consecutive relapses. Percentage of participants with total number of relapses experienced during maintenance period was reported.

Time frame: Baseline up to Week 28

Population: ITT worstcase population signifies participants who prematurely discontinued before the time of first relapse were considered as relapse at following visit.

Maintenance Phase: Percentage of Participants With Scalp Psoriasis Pruritus Score at First Time of Relapse

Pruritus (itching sensation) score of were evaluated on a scale from 0 - 3 (0 = None \[no itching\], 1 = Mild \[slight itching, not really bothersome\], 2 = Moderate \[definite itching that is somewhat bothersome; without loss of sleep\], and 3 = severe \[intense itching that has caused pronounced discomfort; night rest interrupted and excoriations of the skin from scratching may be present\]) , where 0 indicates best and 3 indicates worst. Percentage of participants with scalp psoriasis pruritus score at first relapse was reported.

Time frame: Baseline up to Week 24

Population: ITT worstcase population signifies participants who prematurely discontinued before the time of first relapse were considered as relapse at following visit. Overall number of participants analyzed refer to the participants evaluable for this outcome measure.
