Filter by:The purpose of this study is to compare and evaluate the diagnostic performance of scrape cytology using two different cytological staining techniques, and to evaluate additional touch imprint cytology with that of histopathology of superficial basal cell carcinoma and actinic keratosis.
Topical treatment of mild to moderate actinic keratosis located on the face and head with Solaraze® is known to be a safe and efficient treatment option. However, it is unclear if an expansion of the treatment period to 6 months will increase the rate of complete responses. Therefore the investigators will evaluate the efficacy and safety of the treatment of actinic keratosis with Solaraze® applied twice daily to the face and head over 3 or 6 months of treatment.
The purpose of the study is to compare effectiveness and safety of multiple applications of imiquimod 5% cream and vehicle cream in graft recipients suffering from actinic keratosis.
The purpose of the study is to obtain recurrence rates and long-term safety data for patients who had been treating actinic keratoses on the face and scalp with 5 % Imiquimod Cream in a previous study.
It is believed that imiquimod 5% cream has the potential to be an effective treatment for actinic keratoses. The purpose of this study is to evaluate the duration of the effect of topical imiquimod 5% topical cream for the treatment of actinic keratoses.
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 purpose of this study is to evaluate the safety of one, two, or three cycles of imiquimod for the treatment of AK. The AK lesions treated can be in adjacent and nonadjacent areas of the head, torso, and extremities. The total surface area for the AK lesions must be greater than 25 cm2. The secondary objective is to evaluate the effectiveness of treatment with imiquimod in people with large surface areas of AK.
The purpose of this study is to evaluate the safety and efficacy of imiquimod 5% cream compared to vehicle cream in the treatment of Actinic Keratosis (AK) on the arm and/or hand when the cream is applied once daily 2 days per week for 16 weeks.
This is a 1-year follow-up study to evaluate the long-term effects in subjects who completely cleared their actinic keratosis (AK) lesions in the 1473-IMIQ study. The 1473-IMIQ study evaluated the safety and effectiveness of imiquimod 5% cream compared to a placebo cream for the treatment of AK.
Study Aims: - To compare the long-term efficacy and safety of imiquimod versus vehicle used as an adjunct to cryotherapy. - To assess and compare the recurrence rate and time to recurrence of the 2 different treatment groups. Hypothesis: The imiquimod arm will produce a more prolonged clearing of Actinic Keratoses (AK) compared to the vehicle arm.
The purpose of this study is to determine whether topical application of PEP005 is safe for the treatment of actinic keratoses.
