A gene therapy approach to regulated delivery of erythropoietin as a function of oxygen tension

Current therapy for several forms of anemia involves a weekly regime of multiple subcutaneous injections of recombinant human erythropoietin (hEpo). In an effort to provide a physiologically regulated administration of erythropoietin, we are developing cel ...

Light dosimetry for photodynamic therapy in the esophagus

Hubert van den Bergh, Georges Wagnières

BACKGROUND AND OBJECTIVE: Photodynamic therapy (PDT) is an efficient technique to treat superficial early cancers in the pharynx, esophagus, and tracheo-bronchial tree. However, the lack of selectivity of some of the clinically used photosensitizers can re ...

Gene therapy for amyotrophic lateral sclerosis (ALS) using a polymer encapsulated xenogenic cell line engineered to secrete hCNTF

Patrick Aebischer, Frédéric Kaplan

The gene therapy approach presented in this protocol employs a polymer encapsulated, xenogenic, transfected cell line to release human ciliary neurotrophic factor (hCNTF) for the treatment of Amyotrophic Lateral Sclerosis (ALS). A tethered device, containi ...

Immunoisolated xenogenic chromaffin cell therapy for chronic pain. Initial clinical experience

Patrick Aebischer, Julien Favre

BACKGROUND: Chromaffin cells from the adrenal gland secrete a mixture of compounds that have a strong analgesic effect, especially when administered intrathecally. Many studies in animal models have shown that discordant xenogeneic cell isolates, including ...

Photodynamic Therapy for Cancer of the Upper Aerodigestive Tract Using Tetra(m-hydroxyphenyl)chlorin

Hubert van den Bergh, Georges Wagnières, Alain Woodtli

A major step in the development of photodynamic therapy (PDT) is the clinical optimization and evaluation of new photosensitizers (PS). Ideally, new compounds should be more effective and/or induce fewer side effects than the first generation PS such as he ...

In-vivo fluence rate effect in photodynamic therapy of early cancers with tetra(m-hydroxyphenyl)chlorin

Hubert van den Bergh, Georges Wagnières, Alain Woodtli

Several parameters affect clin. trials in photodynamic therapy and influence the therapeutic outcome. Beside drug dose, light dose, drug-light interval and other variables, the fluence rate is a parameter that can influence the therapeutic results. In this ...

Light distributors for photodynamic therapy

Hubert van den Bergh, Alain Woodtli

A brief overview is given of light distributors developed by our group in Lausanne for photodynamic therapy (PDT) of cancer. We focus on fiber optic devices which have to a large extent been tested over the years in the clinic for PDT of the upper aerodige ...

Importance of fluence rate in photodynamic therapy with ALA-induced PpIX and BPD-MA in a rat bladder tumor model

Georges Wagnières

Oxygen dependent phototoxicity was investigated in vivo in an orthotopic rat bladder tumor model. Two photosensitizers, benzoporphyrin derivative monoacid ring A and 5-aminolevulinic acid-induced protoporphyrin IX were studied. For a given cumulative light ...
