The purpose of this study is to evaluate the efficacy of adding methotrexate to etanercept compared with etanercept monotherapy as measured by the percentage of participants achieving a 75% improvement from baseline in the Psoriasis Area and Severity Index (PASI 75) at Week 24.
Psoriasis is a chronic disorder characterized by erythematous scaly patches which affect the scalp, trunk, extensor surfaces of the limbs and the genital area. The common form of psoriasis is referred to as psoriasis vulgaris. There are several variants of psoriasis such as guttate psoriasis, inverse psoriasis, pustular psoriasis and erythrodermic psoriasis. Psoriasis is highly prevalent in the general population, mainly as a result of its chronicity and the absence of a cure. The estimates of psoriasis prevalence are within the range of 0.5% to 4%. The diagnosis of psoriasis is made on a clinical base, usually by physical examination, performed by a dermatologist. Although skin biopsy may be useful in some cases, there is no laboratory test which may serve as a reference standard to the clinical diagnosis of psoriasis. Psoriasis in its mild cases per se is not associated with excess mortality, however, the disease may affect quality of life of affected patients to a substantial degree. Psoriasis may be readily apparent to others because of scales and redness of the skin. The skin may itch and scales may shed from the patients to the environment or directly on other people. Feelings of stigmatization and major changes in life-style caused by psoriasis have been documented in numerous studies. The burden of the disease may be exaggerated due to expensive therapy and complicated therapeutic regimes Patients with mild to moderate psoriasis are usually treated with topical treatments. Photo-therapy or systemic treatments are reserved to patients with moderate to severe disease. Topical corticosteroids may lead to rapid improvement in psoriasis, however rapid relapse following discontinuation is the common practice leading to chronic use. Calcipotriene ointment may also be used and requires 8 to 12 weeks of use for maximal effect and often causes local irritation, particularly when used on the face. The use is limited to 100 gr/week due to hypercalcemia that might follow systemic absorption. Vitamin A derivative tazarotene may be also be used for plaque psoriasis. Although it can produce longer remissions than topical steroids, local irritation, cost, and teratogenicity limit its use. Coal tar products may be used as steroid-sparing agents, especially useful for enhancing the efficacy of natural sunlight and phototherapy. Application can be cumbersome because of irritation, unpleasant smell, brown color that can stain clothing, and propensity to cause folliculitis. All of the above treatments are particularly problematic for the face and genital psoriasis due to the potential side effects and mainly possible severe irritation reducing patients compliance. Psirelax is a novel topical medication directed for the treatment of patients with psoriasis. The formulation of Psirelax includes the following substances: 5%-15% quince seeds jelly, 10%-40% natural base cream (e.g. Ferntree Cottage Pure Base Cream), 55%-75% mixture of natural anti-oxidants (e.g. Vitamin E, wheat germ oil, Safflower oil), natural skin softening agents (e.g. sweet almond oil, sesame oil), natural absorption aids (e.g. jojoba oil, vegetable squalene), natural tissue regenerating and protecting agents (e.g. grape seed oil, sunflower oil), natural preservatives (e.g. paraben, tea trea essential oil, thyme essential oil, grapefruit seed extract, Vitamin E) and natural thickening agents (e.g. bee wax, aloevera, medicinal Vaseline, coconut oil, guar gum, palm oil, borax) In a preliminary observation, a patient with severe psoriasis applied Psirelax three times each day during four days. The patient reported complete disappearance of the psoriatic plaques and pruritus was reduced by 70%. It was suggested to conduct an open study to assess the effect of Psirelax in patients with psoriasis vulgaris. The aim of this study is to examine the safety and efficacy of Psirelax in the treatment of psoriasis.
The purpose of this study is to evaluate efficacy and safety of indigo naturalis oil extract in treating nail psoriasis.
This study aims to collect Australian data on the prevalence of undiagnosed psoriatic arthritis in patients with plaque psoriasis. In addition the study will assess disease severity and quality of life in Australian patients with psoriasis attending specialist dermatology clinics.
This study will look at how safe and effective, a novel agent, CT 327 cream is in treating patients with mild to moderate psoriasis vulgaris (PV). Patients will be treated twice daily for 8 weeks on specific lesions of PV and safety and symptoms of PV will be assessed throughout the treatment period.
This study proposes to compare 2 different methods for managing a subject with psoriasis who has achieved good disease control, as defined by a clinical response with a Physician Global Assessment (PGA) inferior or equal to 1 at the screening visit, on etanercept treatment. The first method involves stopping etanercept treatment on entry into the study, with the option to reinitiate etanercept at 50 mg once weekly after medical review and agreement between the subject and the investigator. The second method involves continuing on etanercept at 25 mg once weekly, with the option to increase the dose to 50 mg once weekly after medical review and agreement between the subject and the investigator. Subjects will be randomized into one of these two study arms.
This is an investigator-masked, randomized, parallel, clinical study comparing the efficacy of once daily versus twice daily application of Ultravate® ointment (halobetasol propionate 0.05% ointment) in combination with Lac-Hydrin lotion (ammonium lactate topical) in the treatment of stable plaque psoriasis. 1) Phase 1: Patients will be treated for two weeks with combination therapy using Ultravate® ointment with Lac-Hydrin lotion and their psoriasis plaques will be evaluated to test efficacy of the medication. Half the subjects will be randomized to receive treatment with once a day Ultravate® ointment and twice daily Lac-Hydrin lotion; the other half of subjects will receive twice daily Ultravate® ointment with twice daily Lac-Hydrin lotion. Ultravate® ointment will be discontinued following two weeks of treatment, in compliance with its FDA indication. Phase 2: The second treatment phase will consist of a four-week observation period. Subjects will be re-randomized to either continue using twice daily Lac-Hydrin lotion, versus no treatment. The purpose of this second phase of the study is to investigate whether use of Lac-Hydrin monotherapy twice daily can minimize risk of recurrence and maximize duration of therapeutic effect. Part of this clinical study consists of the use of patient and physician satisfaction questionnaires. These questionnaires will include questions about the satisfaction with the formulation of each agent, questions about compliance with treatment, etc. Such questions could be used to demonstrate patient and physician satisfaction with each agent, with combination therapy, and to compare patient satisfaction rates among those randomized to once daily versus twice daily application of Ultravate® ointment. The hypothesis is that Ultravate ointment once daily in combination with Lac-Hydrin twice daily is equal in efficacy to Ultravate ointment twice daily in combination with Lac-Hydrin twice daily.
