Laser-Assisted Immunotherapy (LIT) is intended to a systemic anti-tumor immune response by priming a tumor with laser energy to liberate an array of tumor antigens from whole cells, immediately followed by administration of the immune stimulant Glycated Chitosan (GC), which is designed to activate antigen presenting cells and facilitate the uptake of tumor antigens. In turn, the antigen presenting cells activate the patient's immune system, resulting in an immune response towards the remaining tumor(s).
