Efficacy and Safety of Calcipotriol Plus Hydrocortisone Ointment in Psoriasis Vulgaris on the Face and Skin Folds

LEO Pharma1,245 enrolled

Overview

There are few therapies suitable for the treatment of psoriasis on the face and skin folds. As these areas are sensitive, irritation and other adverse reactions are more common than elsewhere on the body. The purpose of the study is to compare the efficacy and safety of once daily treatment for up to 8 weeks of an ointment containing calcipotriol 25 mcg/g plus hydrocortisone 10 mg/g with calcipotriol 25 mcg/g in the ointment vehicle, hydrocortisone 10 mg/g in the ointment vehicle and the ointment vehicle alone in patients with psoriasis vulgaris on the face and on the intertriginous areas (= double-blind phase). Furthermore, the safety and efficacy will be evaluated for up to 60 weeks treatment as required of calcipotriol 25 mcg/g plus hydrocortisone 10 mg/g ointment in psoriasis vulgaris on the face and intertriginous areas (= open-label phase).

Inclusion Criteria: * Clinical diagnosis of psoriasis vulgaris involving the face * Clinical signs of psoriasis vulgaris on the trunk and/or the limbs, or earlier diagnosed with psoriasis vulgaris on the trunk and/or the limbs * An extent of psoriatic involvement of the face of at least 10 cm2 (the sum of all facial lesions) * Treatment areas (the face and the intertriginous areas) amenable to topical treatment with a maximum of 100 g of ointment per week * Disease severity graded as mild, moderate, severe or very severe according to the investigator's global assessment of disease severity of the face Exclusion Criteria: * Systemic treatments with all other therapies than biologicals, with a potential effect on psoriasis vulgaris (e.g., corticosteroids, vitamin D analogues, retinoids, immunosuppressants) within the 4-week period prior to randomisation * Systemic use of biological treatments, whether marketed or not, directed against or with a potential effect on psoriasis vulgaris (e.g., alefacept, efalizumab, etanercept, infliximab, adalimumab) within 3 months prior to randomisation * PUVA therapy or Grenz ray therapy within the 4-week period prior to randomisation * UVB therapy within the 2-week period prior to randomisation * Topical treatment of the face and the intertriginous areas within the 2-week period prior to randomisation (use of emollients is allowed on treatment areas during this 2-week period, but not during the double-blind phase of the study) * Topical treatment with very potent WHO group IV corticosteroids within the 2-week period prior to randomisation * Initiation of or expected changes in concomitant medication that may affect psoriasis vulgaris (e.g., beta blockers, anti-malaria drugs, lithium and ACE inhibitors) during the study * Current diagnosis of erythrodermic, exfoliative, guttate or pustular psoriasis * Patients with any of the following conditions present on the treatment area: viral (e.g., herpes or varicella) lesions of the skin, fungal and bacterial skin infections, parasitic infections, skin manifestations in relation to syphilis or tuberculosis, rosacea, perioral dermatitis, acne vulgaris, atrophic skin, striae atrophicae, fragility of skin veins, ichthyosis, acne rosacea, ulcers and wounds * Other inflammatory skin diseases (e.g., seborrhoiec dermatitis, contact dermatitis and cutaneous mycosis) that may confound the evaluation of psorisis vulgaris on the face or on the intertriginous areas * Planned exposure to sun, UVA or UVB that may affect the psoriasis vulgaris during the study * Known or suspected severe renal insufficiency or severe hepatic disorders * Known or suspected disorders of calcium metabolism associated with hypercalcaemia

Outcomes

Primary Outcomes

Participants With "Controlled Disease" According to the Investigator's Global Assessment(IGA) of Disease Severity of the Face at Week 8 (Visit 6) in the Double-blind Phase

The (sub) investigator made an assessment of the disease severity of the face using the 6-category scale below. Clear, Almost clear, Mild, Moderate, Severe, Very severe The assessment was made considering the condition of psoriasis vulgaris of the face at the time of the evaluation, not in relation to the condition at a previous visit. For subjects with a baseline (Visit 1) severity of moderate or worse - "controlled disease" of the face was defined as clear or almost clear according to the IGA of disease severity of the face. For subjects with a baseline (Visit 1) severity of mild - "controlled disease" of the face was defined as clear according to the IGA of disease severity of the face.

Time frame: At Week 8 (end of treatment for double-blind phase)

Secondary Outcomes

Participants With "Controlled Disease" According to the IGA of Disease Severity of the Face at Week 4 (Visit 4) in the Double-blind Phase

The assessment of the disease severity of the face was made using the 6-category scale below. Clear Almost clear Mild Moderate Severe Very severe The assessment was made considering the condition of psoriasis vulgaris of the face at the time of the evaluation, not in relation to the condition at a previous visit. For subjects with a baseline severity of moderate or worse - "controlled disease" of the face was defined as clear or almost clear according to the IGA of disease severity of the face. For subjects with a baseline severity of mild - "controlled disease" of the face was defined as clear according to the IGA of disease severity of the face.

Time frame: At Week 4

Participants With "Success" According to Total Sign Score (TSS) of the Face at Week 8 (Visit 6) in the Double-blind Phase

"Success" was defined as a TSS score of 0 or 1. For each clinical sign, a single score, reflecting the average severity of all psoriatic lesions on the face was determined according to the scale below: Redness 0 = none (no erythema) 1 = mild (faint erythema, pink to very light red) 2 = moderate (definite light red erythema) 3 = severe (dark red erythema) 4 = very severe (very dark red erythema) Thickness 0 = none (no plaque elevation) 1 = mild (slight, barely perceptible elevation) 2 = moderate (definite elevation but not thick) 3 = severe (definite elevation, thick plaque with sharp edge) 4 = very severe (very thick plaque with sharp edge) Scaliness 0 = none (no scaling) 1 = mild (sparse, fine-scale lesions, only partially covered) 2 = moderate (coarser scales, most of lesions covered) 3 = severe (entire lesion covered with coarse scales) 4 = very severe (very thick coarse scales, possibly fissured) The sum of the three scores constituted a TSS ranging from 0 to 12

Time frame: At Week 8 (end of treatment for double-blind phase)

Participants With "Controlled Disease" According to the IGA of Disease Severity of the Intertriginous Areas at Week 8 (Visit 6) in the Double-blind Phase

The (sub)investigator made an assessment of the disease severity of the intertriginous areas using the 6-category scale below. Clear, Almost clear, Mild, Moderate, Severe, Very severe The assessment was made considering the condition of psoriasis vulgaris of the intertrigi-nous areas at the time of the evaluation, not in relation to the condition at a previous visit. For subjects with a baseline severity of moderate or worse - "controlled disease" of the intertriginous areas was defined as clear or almost clear according to the IGA of disease severity of the intertriginous areas. For subjects with a baseline severity of mild - "controlled disease" of the intertriginous areas was defined as clear according to the IGA of disease severity of the intertriginous areas.

Time frame: At Week 8 (end of treatment for double-blind phase)

Participants With "Success" According to Total Sign Score of the Intertriginous Areas at Week 8 (Visit 6) in the Double-blind Phase

The severity of the subject's psoriasis vulgaris on the intertriginous areas was evaluated in terms of the three clinical signs: redness, thickness and scaliness. All the defined intertriginous areas were rated separately using the same scale as for the investigator's assessment of clinical signs (redness, thickness and scaliness) of the face. For each clinical sign, a single score, reflecting the average severity of all psoriatic lesions on the face was determined according to the scale below: Redness 0 = none 1. = mild 2. = moderate 3. = severe 4. = very severe Thickness 0 = none 1. = mild 2. = moderate 3. = severe 4. = very severe Scaliness 0 = none 1. = mild 2. = moderate 3. = severe 4. = very severe A mean score was calculated for each sign (redness, thickness and scaliness) based on scores of all the defined intertriginous areas with psoriasis at baseline and the sum of these mean scores constituted the TSS. "Success" was defined as a TSS score of 0 or 1.

Time frame: At Week 8 (end of treatment for double-blind phase)
