Brief summary

The purpose of the study is to compare the efficacy and safety of Clobetasol propionate to that of its Vehicle in the treatment of mild to moderate plaque-type psoriasis.

Detailed description

The purpose of the study is to compare the efficacy and safety of Clobetasol propionate to that of its Vehicle in the treatment of mild to moderate plaque-type psoriasis. This is a multi-center, double blind, randomized, parallel designed study which consists of 2 weeks of treatment and a follow-up visit 2 weeks later.

Female subjects of childbearing potential must have a negative urine pregnancy test result at baseline and practice a reliable method of contraception throughout the study. * Mild to moderate, plaque-type psoriasis * Target lesion on the trunk or extremities (excluding palms/soles, elbows, or knees) with a score of 2 or 3 for each of erythema, scaling and plaque thickness * Able to understand the requirements of the study and sign Informed Consent/HIPAA Authorization Forms. Subjects under the legal age of consent in the state where the study is conducted must also have the written, informed consent of a parent or legal guardian.

Exclusion criteria

* Female subjects who are pregnant (positive urine pregnancy test) breast feeding or who are of childbearing potential and not practicing a reliable method of birth control * Known allergy to clobetasol propionate or other topical corticosteroids; or to any component of the investigational formulations * Subjects who have not complied with the proper wash-out periods for prohibited medications * Medical condition that in the opinion of the investigator, contraindicates the subject's participation in the clinical study * Skin disease/disorder that might interfere with the study related diagnosis or evaluations * Evidence of recent alcohol or drug abuse * History of poor cooperation, non-compliance with medical treatment or unreliability

Design outcomes

Primary

MeasureTime frameDescription
Number of Participants With a Target Lesion Global Improvement (TLGI) Score of 0, 1, or 2 at Weeks 1, 2, and 4Weeks 1, 2, and 4The investigator assessed the TLGI of participants relative to their initial Baseline condition based on a 7-point scale: 0=completely cleared, possible residual discoloration; 1=almost cleared, 90% improvement, very significant clearance with only traces of disease remaining; 2=marked improvement, approximately 75%, with some disease remaining; 3=moderate improvement, approximately 50%; 4=mild improvement, approximately 25%, significant disease remains; 5=no change, no detectable improvement; 6=excerbation, worsening of signs and symptoms of disease.

Secondary

MeasureTime frameDescription
Number of Participants With a Pruritus (Overall) Score of 0 or 1 at Week 2Week 2Participants assessed their level of pruritus (itching) over the previous 24-hour period using the following scale: 0=no itching; 1=minimal, very rarely aware of localized itching, present when relaxing and lasted for very short time; 2=mild, aware of itching at times, present when relaxing, not present when focused on other activities; 3=moderate, often aware of itching, annoying, sometimes disturbed sleep and daytime activities; and 4=severe, constant itching, distressing, frequent sleep disturbance, interfered with activities.
Number of Participants With an Erythema Score of 0 or 1 at Week 2Week 2The investigator individually graded the severity of erythema (redness of skin) in participants as: 0=hyperpigmentation, pigmented macules (flat, distinct, colored area of skin), diffuse faint pink or red coloration; 1=no evidence of erythema, hyperpigmentation present; 2=faint erythema; 3=light red coloration; 4=moderate red coloration; and 5=bright red coloration.
Number of Participants With a Scaling Score of 0 or 1 at Week 2Week 2The investigator individually graded the severity of scaling in participants as: 0=no scaling; 1=no evidence of scaling; 2=minimal, occasional fine scale over less than 5% of the lesion; 3=mild, fine scales predominate; 4=moderate, coarse scales predominate; and 5=marked, thick nontenacious scales predominate.
Number of Participants With a Plaque Thickness Score of 0 or 1 at Week 2Week 2The investigator individually graded the severity of plaque thickness in participants as: 0=no elevation over normal skin; 1=possible but difficult to ascertain whether there is a slight elevation above normal skin; 2=slight but definite elevation, typically edges are indistinct or sloped; 3=moderate elevation with rough or sloped edges; 4=marked elevation typically with hard or sharp edges; and 5=very marked elevation typically with hard, sharp edges.
Number of Participants With a Score of 0 or 1 for Subject Global Assessment at Week 2Week 2Participants assessed all treated areas using the Subject Global Assessment scale: 0=skin completely clear, possible residual hyperpigmentation; 1=psoriasis almost clear, patchy remnants of fine scaling present; 2=psoriasis mild, with small amount of psoriasis remaining (i.e., fine to coarse scales in some areas, definite redness, barely visible plaque thickness); 3=psoriasis moderate, between slight and definitely noticeable; 4=psoriasis very noticeable with redness, scaling, plaque thickness; 5=psoriasis severe with severe redness, thick scaling, and plaques.
Mean Percent Change From Baseline to Week 2 in Pruritus (Target Lesion)Baseline (Week 0) and Week 2Participants assessed their level of pruritus (itching) for the target lesion using a 10 centimeter (cm) Visual Analogue Scale (VAS) with the left side anchored with 0=None and the right side anchored with 10=Very Severe. A target lesion (\>2 cm squared \[cm\^2\]) was considered to be one on the trunk or extremities (excluding palms/soles, elbows, or knees). Percent change from Baseline was calculated as the value at Week 2 minus the value at Baseline (Week 0) divided by the Baseline (Week 0) value \* 100.
Mean Percent Change From Baseline to Week 2 in Percent (%) of Body Surface Area (BSA) AffectedBaseline (Week 0) and Week 2Percent change from Baseline was calculated as the value at Week 2 minus the value at Baseline (Week 0) divided by the Baseline (Week 0) value \* 100.

Number of Participants With a TLGI Score of 0, 1, or 2 at Week 1 and Week 4

The investigator assessed the TLGI of participants relative to their initial Baseline condition based on a 7-point scale: 0=completely cleared, possible residual discoloration; 1=almost cleared, 90% improvement, very significant clearance with only traces of disease remaining; 2=marked improvement, approximately 75%, with some disease remaining; 3=moderate improvement, approximately 50%; 4=mild improvement, approximately 25%, significant disease remains; 5=no change, no detectable improvement; 6=excerbation, worsening of signs and symptoms of disease.

Time frame: Week 1 and Week 4
