NCT ID: NCT05928169 Recruiting - Psoriasis Clinical Trials

Determinants of Chronic Inflammatory Skin Disease Trajectories

Start date: May 1, 2023
Phase:
Study type: Observational

Although it is well known that the clinical expression and course of chronic inflammatory skin diseases are highly variable, there are insufficient epidemiological data on this, and the factors that determine the manifestation, clinical features and course are also largely unknown. There are currently no reliable markers that could predict or delineate patient subgroups to support patient management. The aim of this project is to identify clinical and molecular factors that correlate with disease, disease subtypes and progression through in-depth long-term clinical characterization of patients with chronic inflammatory skin diseases and examination of individual biomaterials.

NCT ID: NCT01497951 Completed - Leukoplakia Clinical Trials

Photodynamic Therapy for Oral Precursor Lesions

PDT
Start date: May 2011
Phase: Phase 3
Study type: Interventional

Pre-malignant lesions are difficult to treat. Even after surgical removal they tend to re-appear. Often the lesions are to large and are apparent on many sites, therefore surgical removal is not always possible. The photodynamic therapy uses a special substance, which is absorbed in cells, and thereafter activated by a defined light. The aim of this study is to compare the photodynamic therapy in potentially malignant lesions to a placebo. The investigators assume a significant better result in photodynamic therapy then treatment with a placebo.
