Active clinical trials for "Dermatitis, Phototoxic"

This pilot study compares three photosensitisers, hexylaminolevulinate (HAL) and aminolevulinic acid nano emulsion (BF-200 ALA) to methylaminolevulinate (MAL) in photodynamic therapy of superficially growing basal cell carcinomas. Study is conducted using randomised prospective double blinded comparing design. Fluorescence is measured in A.U. (Arbitrary Unit) with standardised set-up before and after the exposure. Efficacy is assessed clinically, histologically and by hyperspectral imaging system at 3 months, 12 months and 5 years.

This study will assess changes in visual acuity and corneal symmetry after corneal collagen cross-linking (CXL) of asymmetric corneas.

The goal of this observational study is to evaluate disease-free survival (DFS) in patients with malignant gliomas undergoing neurosurgical procedures using 5-aminolevulinic acid (5-ALA)-based photodynamic therapy

Skin Irritation and Phototoxicity Study of KX01 Ointment 1% in Japanese healthy male subjects

Dermal Safety study to determine the Phototoxicity Potential of FMX-101 4% in Healthy Volunteers

This trial is a 4-day, randomized study to determine the phototoxic potential of MC2-01 Cream when topical application to healthy skin is followed by light exposure.

In this study researchers want to gather information about the potential of Antifungal Cream V61-044 containing Trolamine to produce a phototoxic reaction on the skin. A phototoxic reaction is an irritant reaction of the skin to ultra violet light. In order to find this out the study drug will be applied to the skin of healthy human subjects. By using a solar simulator to generate a UV spectrum similar to that of sunlight the potential of the study drug to produce a superficial reddening of the skin will be measured.

To determine the phototoxic potential of a topically applied article in human subjects.

Vemurafenib is an anti-cancer treatment indicated as monotherapy in the treatment of adult patients with non-resectable or metastatic melanoma carrying a BRAF V600 mutation. Cobimetinib is indicated in combination with Vemurafenib in the treatment of adult patients with non-resectable or metastatic melanoma carrying a BRAF V600 mutation. These treatments are associated with a lot of adverse reactions, which may lead to dose reduction, temporary interruption or discontinuation of treatment, which often leads to treatment failure or a decrease in treatment compliance. The most commonly reported adverse reactions (> 30%) with Vemurafenib are arthralgia, rash, photosensitivity reaction, nausea, alopecia and pruritus. The most commonly reported adverse events (> 20%) associated with Cobimetinib / Vemurafenib are diarrhea, rash, nausea, pyrexia, photosensitivity reaction, increase of alanine aminotransferase, elevation of aspartate aminotransferase, blood creatine phosphokinase elevation and vomiting. The risk of presenting a phototoxicity adverse event with Vemurafenib in monotherapy or in combination with Cobimetinib is very common (≥ 1/10) according to MedDRA. The use of optimal photoprotection including the repeated daily use of external photoprotection products is currently recommended for all patients receiving treatment with vemurafenib or with the combination of vemurafenib and cobimetinib.
