Active clinical trials for "Keratosis, Actinic"

The primary aim of this study is to evaluate the effects of prospective patient education on patient satisfaction with administration of topical 5% 5-fluorouracil cream for the treatment of actinic keratosis involving the face, scalp, upper chest, dorsal hands and forearms. Specifically, this study aims to determine if prospective patient viewing of an educational video delineating treatment effects and expectations improves patient satisfaction and treatment completion rates.

Transient local skin reactions with topical Actinic Keratosis treatments such as 5-FluoroUracil (5-FU) often lead to non-adhesion from patients and thus to treatment failure. In regards to 5-FU treatment, these local reactions are related to the pharmacological action of the molecule. The current therapeutic challenge is to reduce the local reactions induced by 5-FU without interfering with its efficacy, in particular by the use of an emollient cream. The aim of the present study is to investigate how the use of an emollient, namely Dexeryl, could improve the local skin reactions occurring during 4 weeks of a 4% 5-FU treatment.

This trial will be conducted to explore the biological effects in the skin following treatment with PEP005 Gel, 0.05% administered for two consecutive days, assessed by reflectance confocal microscopy.

To determine the comparability of the safety and efficacy of Imiquimod Cream, 3.75% and Zyclara (imiquimod) Cream, 3.75% (the reference listed drug) in subjects with actinic keratosis (AK) of the face or balding scalp. It will also be determined whether the efficacy of each of the two active treatments is superior to that of the Vehicle cream.

The purpose of this study is to correlate pathological features from specimens in order to determine if this new molecular diagnostic technique can be used to detect risk of skin cancer.

Actinic keratoses (AK) are common cutaneous lesions associate with chronic ultraviolet radiation exposure. While most authorities consider AK as a pre-malignant lesion, some consider it as an incipient squamous cell carcinoma (SCC). Among the current therapies for the treatment of AK are excisional surgery, cryosurgery, electrodesiccation and curettage, topical chemotherapy and light therapies. Cryosurgery is considered the gold standard for therapy, however as with other lesion-directed therapies, cryosurgery does not treat subclinical lesions in the surrounding skin. Ingenol mebutate is the active compound in the sap from Euphorbia peplus L. (E. peplus). Topical ingenol mebutate treatment has been approved for the treatment of AKs. The goal of AK therapy for all physicians is to provide an effective, tissue-sparing treatment with good cosmetic results. Ingenol mebutate gel 0.015% has shown to not only have a high clearance rate but also a transient localized inflammatory skin response that resolves quickly without sequelae. However, one common fear about ingenol mebutate is that it's mechanism of action is purely destructive to both AKs and healthy skin, and that retreatment would produce an equally, if not more, caustic result on the skin such as severe erosion, scaling, and erythema. It is our hope to debunk this misconception and demonstrate that reapplication of a second cycle of ingenol mebutate would result in lower LSR scores compared to the LSR in the first cycle of application. We plan to treat 20 subjects. Each qualifying subject will have at least 4-8 non-hypertrophic AKs in a 25 cm2 treatment area on the face or scalp. All subjects will be treated with two cycles of ingenol mebutate 0.015%. The first cycle will be started on Day 1, and the second cycle will be started on Day 29 (four weeks apart). Subjects will utilize the once daily for three days regimen for both cycles.

The rationale of this study is to investigate the effects of topical diclofenac on tumor metabolism in the treatment of actinic keratoses in immunocompetent and immunocompromised patients. Study hypothesis is that topical diclofenac lowers lactate level in skin biopsies of actinic keratoses. Planned number of patients is 38. This study is a monocenter study investigating the effects of 3% diclofenac in 2.5% hyaluronic acid gel on tumor metabolism in the treatment of actinic keratoses. Treatment duration is 3 months. Skin biopsies will be obtained before treatment, at the end of the treatment and four weeks after the treatment. Control biopsies at visit 1 and 3 are performed in healthy, sun damaged and untreated skin. Evaluation of efficacy will be performed at the end of the treatment and four weeks after the treatment. Duration of treatment is 3 months (±4 weeks). Approximately 0,5g Solaraze® 3% gel is applied on a 5cm x 5cm lesion. Solaraze® 3% gel is applied twice daily on the study lesions.

The purpose of this phase 1 trial is to investigate the local tolerability on the finger following exposure to PEP005 Gel 0.015% or 0.05% and hand washing once daily, for 2 or 3 consecutive days.

The purpose of this study is to assess the efficacy, safety and tolerability of Eryfotona AK-NMSC® topical application vs Sunscreen on cancerization field of actinic keratosis patients after 6 months of treatment.

Actinic keratoses (AK) are common cutaneous lesions associate with chronic ultraviolet radiation exposure. While most authorities consider AK as a pre-malignant lesion, some consider it as an incipient squamous cell carcinoma (SCC). In addition, the skin around clinically obvious AK lesions has been subject to the same chronic ultraviolet exposure, resulting in genetic damage and mutations, resulting in "field cancerization." Subclinical AKs may progress to clinical AKs, or even de novo invasive SCCs. Among the current therapies for the treatment of AK are excisional surgery, cryosurgery, electrodessication and curettage, topical chemotherapy and light therapies. With cryotherapy, treated lesion clearance rates at 3 months post-treatment after double-freeze thaw cryotherapy has been reported to be around 76-88%; Overall lesion clearance rate at approximately 5 months post-cryosurgery has been reported to be 35-51%. Imiquimod is a topical immune response modifier and a 5% formulation has been approved for the treatment of AKs in the US as a 2x/week for 16 week regimen and in Europe as a 3x/week for 4 week regimen for 1 or 2 courses of therapy. Topical imiquimod treatment may also reduce subclinical lesions in the treatment area, resulting in fewer "new" AK lesions developing over the same period of time when compared to focal treatment. In a comparison of cryosurgery versus imiquimod for the treatment of AKs, Krawtchenko et al reported initial complete clearance rates of 68 and 85% by clinical assessment, respectively. However, the treatment field sustained clearance rate was 4% versus 73%, respectively. Tan et al reported that while application of imiquimod or vehicle following cryosurgery resulted in comparable target AK clearance rates at 12 weeks of 79% versus 76%, respectively, the imiquimod group had fewer total AKs and fewer subclinical AKs. Imiquimod cream at a concentration of 3.75% has been found in Phase 3 studies to be superior to placebo cream with respect to clearance of AKs using a regimen of up to 2 packets (250 mg of cream per packet, 500 mg total) applied daily to the entire face (approximately 200 cm2) for two 2-week treatment cycles separated by a 2-week no-treatment period. This study aims to examine the benefit of cryotherapy in combination with imiquimod 3.75% compared to cryotherapy alone.
