Filter by:The study team had plans to treat approximately 30 subjects. Each subject that had qualified had at least 4-8 visible AKs on the face and/or scalp. At Day 0, one Actinic Keratosis (AK) in the treatment area had been biopsied via a 3 mm punch. The tissue collected was sent to pathology for confirmatory diagnosis as well as genomic analysis. The remaining AKs had been identified, photographed, and documented on a transparency. One of the remaining AKs was designated as the target lesion. The patient returned to the clinic in 7 days (+/- 3) for suture removal. Approximately two weeks after Day 0, the entire treatment area was treated with imiquimod 3.75% cream. Subjects utilized the 2 weeks on, 2 weeks off, 2 weeks on regimen. Subjects were followed every 2 weeks during treatment (week 2, 4 and 6) and then at 4 and 8 weeks post last-imiquimod application (week 10 and 14). At week 14, a biopsy via a 3 mm punch was done of the target lesion. Yet, if the target lesion was no longer present, a biopsy was done at the site where the lesion was previously located.
The primary purpose of this trial is to evaluate Nano-Pulse Stimulation (NPS) to clear or remove Seborrheic Keratosis (SK) lesions from off-facial areas of healthy adult subjects.
Therapeutic Equivalence of Diclofenac Sodium Gel 3% and Solaraze ®, in the treatment of Actinic Keratosis
The purpose of this study is to understand better if indoor daylight Photo Dynamic Therapy (PDT) can provide effective lesion clearing versus conventional red lamp light therapy.
Erbium:yttrium aluminum garnet (Er:YAG) ablative fractional laser-assisted photodynamic therapy (AFL-PDT) has shown significant benefit for the treatment of actinic keratosis(AK). Er:YAG ablative fractional laser ablates the epidermis and dermis without significant thermal injury, creating microscopic ablation zones (MAZ) in the portion of the skin that the laser is applied to. The formed MAZ depends on the laser parameters such as laser depth, laser density and laser passes, which affect the treatment outcome.
To compare the relative efficacy and safety and of 5-FU Cream to the marketed formulation Efudex® (5-FU) Cream, and to demonstrate the superior efficacy of the two active formulations over that of the Vehicle Control Cream, in the treatment of actinic keratosis.
Guidelines for photodynamic therapy (PDT) of actinic keratosis recommend pretreatment with curettage. The impact of curettage on the treatment effect is, however, not known. The present study aimed to evaluate whether daylight-PDT without curettage would reduce treatment effect compared to daylight-PDT with curettage.
This study is designed as a double-blinded proof of concept of feasibility study to define if the immunosuppression associated with photodynamic therapy (PDT) can be blocked by treatment with cyclo-oxygenase-2 (COX-2) inhibitor celecoxib in comparison to placebo. PDT consists of application of the photosensitizer 5-aminolevulinic acid followed by treatment with a blue light. PDT is used to treat pre-cancerous actinic keratosis on large areas of skin. These studies are a continuation of ongoing studies that indicate that the lipid mediator platelet-activating factor (PAF) is generated in skin following PDT, and that PDT suppresses the immune system. It is hypothesized that PDT-generated PAF results in the immunosuppression associated with PDT. Therefore, it is proposed that a treatment to block that immunosuppression could protect the patient undergoing PDT. Blockers of the PAF system are not currently commercially available. However research studies done at Wright State University using mice indicate that PAF- and PDT-induced immunosuppression is blocked by treatment with COX-2 inhibitors. This study is conducted as a proof of concept. Study length and visit for subjects with actinic keratoses: The first part of the study is completed in 12 days then there are follow up visits at 6 and 12 months. There are a total of 6 separate visits to the research office. Study length and visit for control subjects: The study is completed in 10 days. There are a total of 4 separate visits to the research office.
This study evaluates the potential usefulness of photodynamic therapy with PD P 506 A in patients with actinic keratosis on the upper extremities for the first time.
This Phase I study is designed to evaluate the systemic exposure and safety of KX2-391 Ointment in adult subjects when applied to an area of skin containing at least 5 clinically typical, visible, and discrete Actinic Keratosis lesions on the face or balding scalp.
