Definitions
- the present invention relates to agents which are suitable for the immunotherapy of tumor diseases.
- agents are tumor cells, a tumor cell library containing them and the vaccine comprising the tumor cells.
- the invention relates to a method for producing the tumor cells and the use of these as well as the vaccine and the tumor cell library.
- a wide variety of methods are used to treat tumor diseases.
- Primary tumors are often surgically removed and patients undergo post-treatment in the form of chemotherapy and / or radiation therapy.
- the aim of the aftertreatment is to destroy the remaining tumor cells.
- Immunotherapy methods are also attempted in which tumor cells obtained from the primary tumors are manipulated and returned to the patient. This is intended to sensitize the immune system to the tumor cells, thereby preventing later metastasis.
- the immunotherapy procedures are not yet showing the desired results.
- the sensitization of the immune system is not sufficient, which means that tumor cells remain undetected and can develop into metastases.
- Immunotherapy procedures also require that patient's own tumor cells be used for treatment. This means a great expense and time. In many cases, immunotherapy cannot be carried out at all because insufficient tumor cells are obtained from the individual patient.
- the present invention is therefore based on the object of providing an agent with which immunotherapy of tumor diseases can be carried out, the the above disadvantages can be avoided.
- MHC major histocompatibility complex
- HLA-A HLA-A
- HLA-B HLA-C
- HLA-Dr HLA-Dr
- HLA-DQ HLA-DP genes.
- the applicant has recognized that the expression of MHC I and / or MHC II genes is disturbed in tumor cells. In particular, he found that many tumor cells do not express MHC II genes.
- tumor cells which have a combination of MHC I and MHC II genes which are present in a human and also express them have a high immunogenicity. Such combinations are particularly those given in Table I.
- the immunogenicity of such tumor cells can be increased if they also express costimulatory molecules and / or cytokines.
- the applicant's knowledge is used to provide tumor cells with a combination of MHC I and MHC II genes present in a human, the genes being expressed.
- tumor cells includes tumor cells from any human tumor.
- tumors include mom carcinoma, anogenital carcinoma, lung carcinoma, colon carcinoma, brain tumor, gastric carcinoma, bladder carcinoma, liver cell carcinoma and melanoma.
- the tumor cells can be freshly isolated or in culture. They can also be present as such or in a cell assembly, for example a (primary) tumor or metastasis.
- combination of MHC I and MHC II genes includes any combination of MHC I and MHC II genes that may be present in a human. In particular, the combination is selected from the combinations given in Table I.
- the expression "expressed genes” indicates that the combination of MHC I and MHC II genes is expressed. This can be achieved using standard methods. It is favorable to remove the tumor cells and possibly other cells, e.g. Lymphocytes, from the same patient, are first subjected to tissue typing in order to determine which of the MHC I and / or MHC II genes have an impaired expression. The tissue typing can e.g. by means of serological methods as are known from the "llth International Histocompatibility Workshop". The disturbed expression of the MHC I and / or MHC II genes can then be compensated for by transfection into the tumor cells of corresponding exogenous genes which may be present on expression vectors.
- transfected MHC I and / or MHC II genes can be stable or transient, with stable being preferred.
- the detection of expression can be carried out by conventional methods, e.g. serological procedures, cf. above.
- the above tumor cells also have one or more genes coding for costimulatory molecules and / or cytokines which are expressed.
- costimulatory molecules include B7, such as B7-1 or B7-2, and CD44.
- cytokines include interleukins such as IL-2, GM-CSF, TNF- ⁇ and interferon- ⁇ .
- Another object of the present invention is a method for producing the above tumor cells.
- Such a process comprises the following process steps:
- tissue typing of tumor cells encompasses any method by which the expression of MHC I and MHC II genes can be determined. Reference is made to the above explanations. It may be beneficial for the same patient from whom the tumor cells originate to have other cells, e.g. Lymphocytes undergo tissue typing. This makes it even easier to determine the combination of MHC I and MHC II genes suitable for this patient.
- transfection of tumor cells encompasses any method by which MHC I and / or MHC II genes can be transfected in tumor cells. Reference is made to the above explanations.
- selection for tumor cells encompasses any method by which selection can be made for tumor cells which express the MHC I and MHC II genes. Reference is made to the above explanations.
- the tumor cells are also transfected with one or more genes coding for costimulatory molecules and / or cytokines and for expression selected these genes.
- Another object of the present invention is a tumor cell library comprising the above tumor cells. It is preferred if the tumor cells originate from any human tumor and comprise any combination of MHC I and MHC II genes present in a human. The tumor cells particularly preferably comprise the combinations of MHC I and MHC II genes given in Table I.
- Another object of the present invention is a vaccine containing the above tumor cells and common adjuvants, e.g. Buffers, carriers and diluents. It is preferred if the vaccine comprises tumor cells from different tumors, each with the same combination of MHC I and MHC II genes.
- common adjuvants e.g. Buffers, carriers and diluents. It is preferred if the vaccine comprises tumor cells from different tumors, each with the same combination of MHC I and MHC II genes.
- the present invention provides tumor cells in which a combination of MHC I and MHC II genes is expressed, the combination being in a human.
- the combination is one that many people have.
- the tumor cells according to the invention thus represent an agent which can be administered not only to a specific person, but to many people.
- the tumor cells come from any human tumor.
- the present invention is not restricted to the treatment of a specific tumor, but can be used for any spectrum of tumors.
- suitable tumor cells according to the invention for example from the tumor cell library, can be selected and administered to the patient. It is favorable if before Administration of the tumor cells prevents replication by measures such as radiation.
- the present invention enables prophylactic measures against all possible tumors. For this it is only necessary to carry out a tissue typing of cells of the person to be treated and then to administer a suitable vaccine according to the invention.
- the present invention thus represents a breakthrough in the field of immunotherapy for tumor diseases.
