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.
Organ transplant recipients (OTR) have an increased risk of non-melanoma skin cancer, in particular squamous cell carcinoma (SCC), often developing in areas of field cancerization, areas with multiple precancerous actinic keratoses. The risk of developing SCC in OTR is 65-100-fold the normal population (Jensen 1999, Lindeløf 2000), and this cancer often runs a more aggressive course with metastasis reported to occur in 5-8% of cases (Berg 2002). The treatment options in field cancerization are limited. In Norway, the registered treatment alternatives are the topical immune response modifier imiquimod and photodynamic treatment. Neither of these treatments has shown long term beneficial effects. In this study, we will study the effect of pre-treating the skin with ablative, fractional carbondioxide laser before photodynamic therapy in a group of OTR with multiple actinic keratoses
The main purpose of this trial is to demonstrate the predictive value of the clinical diagnosis of clearance of Actinic Keratoses after treatment with Ingenol Mebutate using histopathological examination as the standard.
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.
To identify the Maximum Tolerated Dose levels of ingenol mebutate gel after once daily treatment for 2 or 3 consecutive days and to evaluate efficacy of ingenol mebutate gel in different doses after once daily treatment for 2 or 3 consecutive days compared to vehicle gel
The global aim of this study is to investigate how microneedles can facilitate the penetration and efficacy of photodynamic therapy in the treatment of actinic keratoses The specific aims are as follows: 1. Investigate whether pretreatment with microneedles enhances penetration of topical aminolevulinic acid (ALA) that is marketed as Levulan® Kerasticks by DUSA pharmaceuticals Inc. 2. Investigate whether pretreatment with microneedles can decrease the required incubation times of the topical ALA prior to exposure to blue light photodynamic therapy.
Determine the recurrence rate of actinic keratosis (AK) lesions in patients with complete clinical clearance at the end of the previous trial SP848-AK-1101 at 6 and 12 months of follow-up.
The purpose of this study is to determine if the new vehicle formulations containing ingenol mebutate are as safe and effective as Picato® gel 0.05% (it's current vehicle formulation) when applied to AK lesions on the forearm for two consecutive days.
The objective of this study is to compare the relative efficacy and safety of the test formulation Imiquimod 3.75% Topical Cream to the marketed formulation Zyclara® (imiquimod) 3.75% Topical Cream in the treatment of actinic keratosis. Both the test and reference formulations will also be compared to a placebo cream to test for superiority.
