Safety and Efficacy of TACLONEX Ointment in Adolescent Patients (Aged 12 to 17 Years) With Psoriasis Vulgaris

LEO Pharma33 enrolled

Overview

The purpose of this study is to evaluate the safety and efficacy of 4 weeks of TACLONEX ointment in adolescent patients with psoriasis vulgaris.

TACLONEX ointment has marketing approval in many countries for the treatment of psoriasis vulgaris in adults. No studies have been conducted in patients less than 18 years of age. However, about 25% of affected individuals are diagnosed between 10 and 19 years of age, hence psoriasis is also prevalent in the adolescent age group (12-17 years). All patients will receive TACLONEX. To evaluate the safety of TACLONEX ointment, all adverse events will be recorded. In addition, any systemic absorption of the active components, betamethasone dipropionate and calcipotriene, will be evaluated by assessing adrenal function (using CORTROSYN™ test) and calcium metabolism (by measuring serum calcium and the urinary calcium:creatinine ratio), respectively.

Exclusion Criteria: * Serious allergy, serious asthma, or serious allergic skin rash. * A history of sensitivity to any medication. * PUVA or Grenz ray therapy, UVB therapy, systemic treatment with biological therapies, corticosteroids, or other therapies with an effect on psoriasis, topical treatment with corticosteroids or vitamin D analogues, treatment with enzymatic inductors, cytochrome P450 inhibitors, hypoglycemic sulfonamides, antidepressive medications, estrogen therapy, calcium supplements or vitamin D supplements. * Guttate, erythrodermic, exfoliative or pustular psoriasis. * Viral lesions of the skin, fungal or bacterial skin infections, ulcers or wounds. * Severe renal insufficiency, severe hepatic disorders, disorders of calcium metabolism associated with hypercalcemia, any cardiac condition or endocrine disorder. * Diabetes mellitus * Cushing's disease or Addison's disease.

Outcomes

Primary Outcomes

Adverse Drug Reactions

The number of participants experiencing each type of adverse drug reaction. Adverse drug reactions were defined as adverse events for which the investigator had not described the causal relationship to trial medication as "not related".

Time frame: Week 4

Serum Cortisol Concentration of ≤18 mcg/dL at 30 Minutes After ACTH-challenge at End of Treatment

The ACTH(Adrenocorticotropic hormone)-challenge test involves injecting a synthetic subunit of ACTH into the patient,and measuring the cortisol produced by the adrenal glands 30 and 60 minutes after the injection.

Time frame: Week 4

Serum Cortisol Concentration of ≤18 mcg/dL at 30 and 60 Minutes After ACTH-challenge at End of Treatment

Time frame: Week 4

Change in Albumin Corrected Serum Calcium From Baseline to End of Treatment

Time frame: Baseline and 4 weeks

Change in Urinary Calcium:Creatinine Ratio From Baseline to End of Treatment.

Time frame: Baseline and 4 Weeks

Secondary Outcomes

"Controlled Disease"(i.e., "Clear" or "Almost Clear") According to the Investigator's Global Assessment of Disease Severity at Week 4.

The investigator made an assessment of the disease severity (Plaque thickening, Scaling and Erythema) using a 6-point scale (Clear, Almost clear, Mild, Moderate, Severe, and Very severe). This assessment represented the average lesion severity on the trunk and limbs.

Time frame: Week 4
