    • The present invention concerns a new method for ex-vivo purging of cells in autologous transplantation, wherein the sample of taken cells is treated with a sufficient amount of a multimeric form of the soluble portion of FasL to kill malignant cells without substantially affecting viability of cells to be transplanted. Autologous stem cell transplantation (ASCT) following high-dose chemotherapy with or without radiotherapy has become the standard therapy for the majority of patients with large-cell lymphomas, multiple myeloma, and refractory/recidivating Hodgkin's disease. Such therapy is nowadays also contemplated for selected patients with low-grade lymphomas (chronic lymphocytic leukemia, follicular lymphoma, mantle cell lymphoma) and for patients with acute myeloid leukemia (AML). Current treatments for cell purging include chemotherapy and antibody cocktails. These treatments are often toxic on stem cells and not efficient in eliminating cancer cells. Thus, there is an unmet medical need for cell purging in ASCT which this project will address.
    • 本发明涉及一种在自体移植中离体清除细胞的新方法,其中用足够数量的多聚体形式的FasL的可溶性部分处理所取细胞的样品以杀死恶性细胞,而不会基本上影响细胞的活力 被移植。 大剂量放化疗后的自体干细胞移植(ASCT)已经成为大多数大细胞淋巴瘤,多发性骨髓瘤和难治性/复发性霍奇金病患者的标准治疗方法。 对于低度淋巴瘤(慢性淋巴细胞白血病,滤泡淋巴瘤,套细胞淋巴瘤)和急性骨髓性白血病(AML)患者,目前也考虑了这种治疗方法。 目前用于细胞清除的治疗方法包括化疗和抗体鸡尾酒。 这些治疗通常对干细胞是有毒的,并且不能有效地消除癌细胞。 因此,本项目将针对ASCT中的细胞清除未满足的医疗需求。
