Abstract: The present invention relates to a hydroxyapatite and/or tricalcium phosphate powder characterized in that it has undergone at least one sintering step at a temperature between 400° C. and 600° C. The invention also relates to a process for preparing such a powder, and to a composition comprising such a powder for use as an anti-tumour auto-vaccine and particularly in the treatment of the following pathological conditions: osteosarcoma, B or T lymphoma, mammary tumour, melanoma, haemangiosarcoma, mastocytoma, fibrosarcoma, brain tumours and schwannoma in a subject. The present invention also covers a drug combination comprising the composition of the invention and at least one second therapeutic agent, preferably an anti-tumour agent and/or a radiotherapeutic agent.

Abstract: The invention relates to an autologous cancer vaccine and also to the method for producing same comprising the following steps: a) extracting the proteins contained in a serum or plasma sample obtained from a patient suffering from cancer; and b) bringing the proteins extracted in step a) into contact with particles of hydroxyapatite and/or tricalcium phosphate.

Abstract: The invention relates to a medicament characterized in that it comprises at least one solid biocompatible support, preferably in powder form, on which at least one active substance, preferably selected among biological materials and/or biological molecules, is adsorbed or on which it is to be adsorbed, preferably without requiring a coupling agent. Said solid biocompatible support is capable of purifying the active substance. The invention relates to also relates to a method for preparing a medicament of the aforementioned type, this method essentially consisting of placing at least one solid biocompatible support, preferably in powder form, in contact with at least one active substance, preferably selected among biological materials and/or biological molecules, in such a manner that the active substance is reversibly adsorbed and without denaturing on the support.
