Active clinical trials for "Skin Diseases"

The purpose of the study is to determine the therapeutic effect of alitretinoin, a retinoid, on severe, therapy refractory chronic hand dermatitis.

Chronic sun exposure enhances the incidence of cutaneous neoplasms (NMSC - non melanoma skin cancer), wrinkles, roughness, telangiectasia and irregular pigmentation of the skin. Nowadays, actinic keratosis (AK) are considered in situ squamous cell carcinoma (SCC), and should be managed that way. Conventional topical Photodynamic therapy (PDT) has proven its efficacy on treatment of AK and cancerization field. PDT's action in global improvement of photodamaged skin, texture, pigmentation and reduction of wrinkles has been well documented in literature. Immunohistochemical and histopathological essays describe the hypothesis of conventional PDT's mechanisms of action in photoaging by dermal remodeling, with enhancement of collagen, statiscally significant. Daylight-Photodynamic Therapy (DL-PDT) is a new modality that keeps the efficacy of topical PDT in treatment of AK and cancerization field, but painless and more practically. Until this moment, there is no report of DL-PDT efficacy on photorejuvenation and actinic keratosis evaluated by clinical, histopathological and immunohistochemical studies. The investigator's aim is to evaluate the alterations induced by isolated DLPDT or DLPDT associated with other techniques of transepidermal drug delivery (microneedles, CO2 laser and microdermabrasion) in the treatment of field cancerization in photodamaged skin with actinic keratosis, through clinical evaluation, histopathological and immunohistochemical studies. It is an interventional, prospective, randomized controlled, parallels-groups, four-arm trial with 1:1 allocation ratio study performed in forty patients attended at the Dermatology Service of Hospital Universitário Antonio Pedro- Universidade Federal Fluminense.

Almost 35% of patients treated to dermatosis have some psychiatric disorder. The aim of this study is to evaluate the prevalence and severity of skin picking disorder and other dermatosis, and also test the efficacy of an online-delivered cognitive-behavioral therapy to improve skin picking disorder severity.

A prospective, open, post-market study that will enroll male and female subjects diagnosed with foot fungus and at least one of the following conditions: heel cracks, calluses and/or dry feet. The investigation will consist of approximately 48 subjects (considering a 10% drop-out/screening failure rate) fulfilling the eligibility criteria for the study. Each subject will be treated with the study product, BioCool Footcare (footbath), for 3 weeks. The study duration is estimated to 5 months including recruiting, treatment and follow-up period.

Fractional laser has become an important laser modality in management of a number of skin conditions and photoaging. Fractional photothermolysis is the fractional emission of light into microscopic treatment zones, creating small columns of injury to the skin in a pixilated fashion. Epidermal and dermal disruptions occur in these focal zones of thermal injury, stimulating dermal collagen production and elastic tissue formation. Fractional laser has been used successfully to treat photodamage and overall dyschromia in the Caucasian population. However, there is not much improvement in Asian population. Photoaging refers to the skin caused by intense and chronic exposure to sunlight. The visible effects of photoaging are fine wrinkles, mottling, pigmentation and roughness of the skin. These changes are usually associated with chronologic aging. However, photoaging is not a good indicator of chronologic age. It just makes a person look older than his or her chronologic age. Skin ageing may be divided into two processes: intrinsic ageing and extrinsic ageing (or photoageing). Both are accompanied by changes in the morphological and biomechanical properties of skin. Profile HaloTM dual-wavelength fusion fractional laser is the first hand tool in the world that integrates ablative and non-ablative fractional lasers. It includes a non-ablative fractional laser with a wavelength of 1470nm and an ablative fractional laser with a wavelength of 2940nm. A day after treatment, new epithelial tissue began to appear, and the necrotic epidermis formed microepidermal necrotic debris (MENDs). MENDs were surrounded by keratin 2-7 days after treatment, and collagen sequence in MTZs was changed 7 days later. The 2940 ablative fractional laser can be added with 20-100 micron lattice stripping, ensuring safety while enabling MENDs to be peeled off 2 days earlier and reducing the risk of side effects. This makes the laser safe and effective compared with the single fractional laser and reduces the downtime.

Atopic Dermatitis (AD), also known as eczema, is a common skin disease characterized by itchy lesions. The prevalence of AD has increased over the past few decades, with 15-30% of children and 2-10%of adults being affected. The lesions of AD patients are very inflamed, with an increased number of inflammatory cells in the skin. There are not many medications available that are fully effective and can be used long-term for treatment of atopic dermatitis. Benralizumab is a monoclonal antibody used for treatment of a type of asthma called "eosinophilic asthma". Atopic dermatitis is also associated with elevated levels of eosinophils, and we would like to determine if benralizumab is effective in patients with atopic dermatitis. This is a randomized, double-blind, parallel group, placebo-controlled study will evaluate the effect of 3 doses of a fixed 30 mg dose of benralizumab administered subcutaneously (SC) every 4 weeks to patients with moderate-to-severe atopic dermatitis, on the severity of atopic dermatitis, and the cellular inflammation of skin lesions in these patients. Anti-inflammatory properties of benralizumab when a skin flare is induced in a controlled laboratory setting, in addition to the effects of benralizumab on skin that is already inflamed will be examined.It is hypothesized that benralizumab will attenuate eosinophilic inflammation in the skin.

B7451014 is a Phase 3 study to investigate PF-04965842 in patients aged 12 years and over with a minimum body weight of 40 kg who have moderate to severe atopic dermatitis. Subjects responding well to an initial open-label 12 week treatment of PF-04965842 (200 mg) taken orally once daily (QD) will be identified and randomized in a double-blind manner to receive 200 mg QD PF-04965842, 100 mg QD PF-04965842, or QD placebo. Efficacy and safety of 2 doses of PF-04965842 will be evaluated relative to placebo over 40 weeks. Subjects experiencing significant worsening of their symptoms, i.e., protocol-defined flare, enter 12 weeks rescue treatment and receive 200 mg PF-04965842 together with a marketed topical medicine. Eligible patients will have the option to enter a long-term extension study after completing the initial 12 week treatment, the 12 week rescue treatment, and the 40 week blinded treatment.

Vitamin D(Vit D) is a pro-differentiation agent that enhances the accumulation of protoporphyrin IX (PpIX) after MAL(methyl-aminolevulinate) incubation in actinic keratosis and may have significant benefit for the treatment of actinic keratosis by ablative fractional laser-primed photodynamic therapy (AFL-PDT).

B7451029 is a Phase 3 study to investigate PF-04965842 in adult patients who have moderate to severe atopic dermatitis and use background topical therapy. The efficacy of two dosage strengths of PF-04965842, 100 mg and 200 mg taken orally once daily will be evaluated relative to placebo over 12 weeks. The efficacy of the two dosage strengths of PF-04965842 will be compared with dupilumab in terms of pruritus relief at 2 weeks. The two dosage strengths of PF-04965842 and dupilumab 300 mg injected subcutaneously once every two weeks (with a loading dose of 600 mg injected on the first day) will also be evaluated relative to placebo over 16 weeks. The safety of the investigational products will be evaluated over the duration of the study. Subjects will use non-medicated emollient at least twice a day and medicated topical therapy such as corticosteroids, calcineurin inhibitors or PDE4 inhibitors, as per protocol guidance, to treat active lesions during the study. Subjects who are randomized to receive one of the two dosage strengths of PF-04965842 will also receive placebo injectable study drug every two weeks until Week 16 and then will continue on receiving only the oral study drug for 4 weeks. Subjects who are randomized to receive dupilumab injections every two weeks will also receive oral placebo to be taken once daily until Week 16 and will then continue to receive only the oral placebo for 4 weeks. Subjects who are randomized to the placebo arms, will receive both daily oral placebo and injectable placebo every two weeks until Week 16, after which they will receive either 100 mg or 200 mg of PF-04965842 taken orally once daily for 4 weeks, dependent upon which arm they have been allocated to. Eligible subjects will have an option to enter a long-term extension study after completing 20 weeks of treatment.
