Filter by:The purpose of this study is to determine whether imiquimod creams are effective in treating Actinic Keratoses when applied to the face or balding scalp. Actinic keratosis (AK) is a skin condition that shows up on skin routinely exposed to the sun, such as the face, scalp, shoulders, chest, back, arms, and hands. The active ingredient contained in the study cream for this study is the same as that of the approved product Aldara, which has been shown to be safe and effective for the treatment of AKs.

The purpose of this study is to compare the efficacy of photodynamic therapy with 5-aminolevulinic acid and intense pulsed light vs absence of treatment for actinic keratoses.
The purpose of this study is to examine the safety and toleration of PEP005 Topical Gel, administered on an actinic keratosis (AK) treatment area on the top of a hand.
The purpose of this study is to determine the extent of systemic absorption of PEP005 when applied topically for the treatment of actinic keratoses.
The aim of this study is to provide this investigational drug to patients who cannot be optimally treated with conventional therapies and to collect efficacy and safety data on the use of Metvix PDT in subjects with field actinic keratoses, large/multiple superficial basal cell carcinomas (BCCs) or Bowen's disease.
RATIONALE: Photodynamic therapy uses a drug that becomes active when it is exposed to a certain kind of light. When the drug is active, abnormal cells are killed. Photodynamic therapy using topical aminolevulinic acid may be effective against actinic keratosis. PURPOSE: This randomized clinical trial is studying how well different photodynamic therapy regimens using topical aminolevulinic acid work in treating patients with actinic keratosis.
Patients on immunosuppressive therapy, e.g. organ recipients, have a higher occurrence of AK than the untreated population. Keratotic lesions (i.e. AK lesions and warts) in this population is highly associated with development of SCC also with 10 times higher mortality rate because of SCC than expected. The risk of developing skin cancer, predominantly SCC and BCC, increases with graft survival time and the length of immunosuppressive treatment period. The higher risk of developing skin malignancy and more aggressive skin malignancies in this population, indicate the need for early removal of these pre-malignant lesions. In this study, two contralateral areas (5x10 cm2) with skin lesions within the patient will be compared. One area will receive Metvix PDT at defined intervals and the other will receive lesion specific treatment at the discretion of the investigator. The primary end-point will be the accumulated number of new lesions during the study and number of AK lesions that show complete response 3 months after baseline. Secondary endpoints will be number of BCC lesions that show complete response, number of recurrent lesions, assessment of cosmetic outcome and safety.
The objective of the study is to evaluate the use of sunlight instead of red light during photodynamic therapy of actinic keratoses using methyl aminolevulinate
The purpose of this study is to determine the optimal tolerated regime of PEP005 for the treatment of actinic keratoses of the face or face and scalp.
