Safety Study: Combined Modality Treatment for Non-Small Cell Lung Cancer

The photopheresis apparatus and procedure will be identical to that currently used. Patients will receive intravenous 8-MOP (UVADEX®) directly into the photopheresis apparatus, to yield a concentration of 50-200 ng/ml of drug. The blood will be leukapheresed to obtain a buffy coat and will then be passed through the contiguous closed circuit ultraviolet A exposure device, delivering the desired 1-2 joules/cm2 of ultraviolet A energy. In this manner 2-4 molecules of 8-MOP will be induced to bind covalently to thymines of the leukocyte DNA. At that point, the single variation from the standard treatment will be initiated. Instead of returning the patient's cells and the saline to the patient, the bag will be detached from the apparatus. KLH (depyrogenated, endotoxin-free; Calbiochem-Novabiochem Corp., San Diego, CA) will be added at a concentration of 10 g/ml to the DC-rich leukocyte culture prior to overnight culture.
