Phase 01 Clinical Trials

LMP和DCTD之间的合作推动了几种新的药效分析方法的开发，包括肿瘤组织活检组织中伽马H_2AX(DNA双链断裂检测器)的超灵敏免疫荧光分析，以及拓扑异构酶I和聚ADP-核糖聚合酶(PARP)的ELISA分析。这些分析对于PARP抑制剂与拓扑异构酶I抑制剂以及在NIH临床中心激活的新型非喜树碱拓扑异构酶I抑制剂的首次人体临床试验至关重要。此外，与医学肿瘤科的合作促进了与四氢尿苷联合使用的新DNA甲基转移酶抑制剂氟脱氧胞苷的开发，这是DCTD生产的供CCR研究的药物。

The collaboration between the LMP and DCTD has been responsible for the development of several new pharmacodynamic assays, including an ultrasensitive immunofluorescence assay for gamma H2AX (DNA double strand break detector) in tumor tissue biopsies, and ELISAs for topoisomerase I and poly ADP-ribose polymerase (PARP). These assays have been essential for first in human clinical trials of PARP inhibitors in combination with topoisomerase I inhibitors as well as of novel, non-camptothecin topoismerase I inhibitors that have been activated in the NIH Clinical Center. In addition, collaborations with the Medical Oncology Branch have facilitated the development of the new DNA methyltransferase inhibitor fluorodeoxycytidine used in combination with tetrahydrouridine, drugs that have been produced by DCTD for study by the CCR.
