    • This invention provides novel replication-defective adenoviral vectors comprising an adenoviral genome in which the protein IX gene, preferably under the control of its own promoter, is in an inverted orientation relative to the direction of transcription of the native protein IX gene at a location where the protein IX gene normally resides, for production of replication-competent adenovirus (RCA) free, or substantially RCA-free, adenovirus preparations. Said vector preferably encodes a gene of interest. The invention relates to viral particles, host cells and compositions comprising said adenoviral vector. This invention further relates a method for propagating adenovirus preparations, free, or substantially free, of replication-competent adenovirus (RCA) particles, from host cells comprising vectors of this invention, for use to treat a subject suffering from a disease or disorder or to prevent a subject from getting a disease or disorder, such as cancer. The invention also provides methods of treating such subjects and methods of prophylactically treating unaffected subjects. This invention further provides for vaccine compositions comprising the novel replication-defective adenoviral vectors of the present invention.
    • 本发明提供了包含腺病毒基因组的新型复制缺陷型腺病毒载体,其中优选在其自身启动子控制下的蛋白质IX基因相对于天然蛋白IX基因的转录方向处于倒置方向, 蛋白IX基因通常存在,用于产生无复制的腺病毒(RCA)或基本上不含RCA的腺病毒制剂。 所述载体优选编码感兴趣的基因。 本发明涉及包含所述腺病毒载体的病毒颗粒,宿主细胞和组合物。 本发明还涉及从包含本发明载体的宿主细胞中扩增游离或基本上游离的具有复制能力的腺病毒(RCA)颗粒的腺病毒制剂的方法,用于治疗患有疾病或病症的受试者或 防止受试者患有疾病或病症,如癌症。 本发明还提供了治疗这些受试者的方法和预防性治疗未受影响的受试者的方法。 本发明进一步提供包含本发明的新型复制缺陷型腺病毒载体的疫苗组合物。
