THERAPEUTIC CANCER VACCINE BASED ON STRESS PROTEINS RENDERED IMMUNOGENIC

摘要

The invention describes a method for preparing a composition comprising tumour cell stress proteins, said method comprising the following steps: providing tumour cells in a culture medium; subjecting the tumour cells under i) to a stress with the result that these cells produce stress proteins in response to the stress; obtaining or recovering stressed tumour cells and/or stress proteins; treating the stressed tumour cells and/or the stress proteins obtained with a molecule or a process capable of rendering the stress proteins immunogenic, preferably a hapten or haptenization. The invention also describes a pharmaceutical composition comprising tumour cell stress proteins and/or tumour cells comprising stress proteins, these stress proteins being rendered immunogenic, and are in particular haptenized, and a pharmaceutically acceptable excipient.
