Abstract

One of the challenges of incorporating molecularly targeted drugs into multi-agent chemotherapy (backbone) regimens is defining dose-limiting toxicities (DLTs) of the targeted agent against the background of toxicities of the backbone regimen. An international panel of 22 pediatric acute lymphocytic leukemia (ALL) experts addressed this issue (www.ALLNA.org). Two major questions surrounding DLT assessment were explored: (1) how toxicities can be best defined, assessed, and attributed; and (2) how effective dosing of new agents incorporated into multi-agent ALL clinical trials can be safely established in the face of disease- and therapy-related systemic toxicities. The consensus DLT definition incorporates tolerance of resolving Grade 3 and some resolving Grade 4 toxicities with stringent safety monitoring. This functional DLT definition is being tested in two Children's Oncology Group (COG) ALL clinical trials.

摘要

将分子靶向药物纳入多药化疗(骨干)方案的挑战之一是在骨干方案毒性的背景下定义靶向药物的剂量限制毒性(DLT)。一个由 22 名儿科急性淋巴细胞白血病(ALL)专家组成的国际小组解决了这个问题(www.ALLNA.org)。围绕 DLT 评估有两个主要问题:(1)如何最好地定义、评估和归因毒性;(2)如何在疾病和治疗相关的全身毒性的情况下安全地建立新药物纳入多药 ALL 临床试验的有效剂量。共识 DLT 定义包括耐受缓解 3 级和一些严格安全监测的缓解 4 级毒性。这个功能 DLT 定义正在两个儿童肿瘤学组(COG)ALL 临床试验中进行测试。
