Active clinical trials for "Keratosis"

This study investigates 5-fluorouracil cream prescription trends by general practitioners for the treatment of field changes of actinic keratosis over the years 2016-2021. The aim is to analyse whether the publication of the multidisciplinary guideline on suspect skin lesions for general practitioners in 2017 has made an impact in the prescribing behaviour of general practitioners.

This project aims to treat field cancerization ( pre-skin cancers) in a manner that will reduce the future pre-skin cancers and non-melanoma skin cancers in patients with significant photodamage. This is 3 year prospective, randomized, controlled comparison of a single treatment with carbon dioxide laser resurfacing vs. carbon dioxide resurfacing plus autologous epidermal skin graft from a non sun exposed site vs. control. Thirty subjects will receive treatment with each of the modalities. The primary measures of efficacy are (a) count of the number of actinic keratosis and non melanoma skin cancers, (b) blinded evaluation of severity from standard digital photographs taken before and after the treatments, and (c) change in histology before and after treatment. Safety measures include (a) pain, (b) scarring, (c) wound healing, (d) and infection

The aim of this study is to determine the effectiveness of combination calcipotriene 0.005% foam and 5% fluorouracil cream for the treatment of actinic keratoses on the scalp. The data obtained will be compared with the current standard of care, monotherapy with 5% fluorouracil cream. A recent randomized, double-blind clinical trial (NCT02019355) compared 0.005% calcipotriol ointment and fluorouracil 5% cream with Vaseline plus fluorouracil 5% cream for a 4-day treatment of actinic keratoses on the face, scalp and upper extremities. They found that calcipotriol plus 5-FU versus Vaseline plus fluorouracil 5% cream led to an 87.8% versus 26.3% mean reduction in the mean number of actinic keratoses. Our study will independently assess the effectiveness of combination treatment (calcipotriene 0.005% foam and fluorouracil 5% cream) on scalp actinic keratoses in a case series of up to 15 eligible participants. Participants will complete a 4-night application of combination treatment with follow-up immediately after and 8 weeks later.

The substance ingenol mebutate (IM) is registered in Switzerland and many countries worldwide for the treatment of actinic keratosis (AK). There is no data on the use of IM in organ transplant recipients, a population highly affected by AK and skin cancer at large. The investigators want to study the use of IM against AK in this high-risk group of patients and assess its safety. The investigators are hoping to prove that IM is safe to use in AK of organ transplant recipients, allowing its use in the clinical routine treatement of AK also in this subset of patients with AK.

The purpose of this study is to determine and compare the safety and efficacy of broad area photodynamic therapy with aminolevulinic acid (ALA-PDT) versus vehicle PDT (VEH-PDT) in the treatment of actinic keratoses (AK) and reduction of new non-melanoma skin cancer (NMSC) of the scalp or both forearms in solid organ transplant recipient subjects receiving chronic immunosuppressive therapy.

This prospective study aims to evaluate the responsiveness of the validated investigator global assessment (IGA) and composite area index score for keratosis pilaris by data collection through treatment and scoring sessions held at a private practice and relevant statistical analysis.

This study compares the efficacy and tolerance of a new device (FLEXITHERALIGHT) for photodynamic therapy in the treatment of keratosis actinic in comparison of classical PDT with Aktilite®.

Keratosis pilaris (KP) is a benign skin condition that often is very frustrating for the patients and treating physicians. The investigators are interested to see if the study product is effective in treating moderate to severe KP.

The purpose of the study is to evaluate the safety, tolerability and treatment effect of tirbanibulin ointment 1% when applied to a field of approximately 100 cm^2 on the face or balding scalp.

A double-blind, placebo controlled study conducted at a single study site. Evaluating the role of systemic antihistamine therapy in the reduction of adverse effects associated with topical 5-aminolevulinic acid photodynamic therapy.
