- W2891736782 abstract "e20071 Background: Data Monitoring Committees (DMCs) are an important component of the clinical trial process. They are charged with reviewing interim data and making recommendations to protect the safety of trial participants and ensure the scientific integrity of the study. Oncologists may be involved with the DMC process in a number of ways – as a DMC member, as an investigator, as a sponsor, or in a regulatory role. This presentation will discuss novel aspects of the DMC review process that are particularly relevant for oncology trials. Methods: The authors are leaders of a Contract Research Organization (CRO) that specializes in providing independent DMC services for government and industry sponsored trials. They have worked with hundreds of unique DMCs and facilitated approximately 1,000 DMC meetings. The proposed methodologies for maximizing the efficiency and thoroughness of DMC reviews are based on extensive experience and well-established principles. Results: Topics that will be covered include: Discrepant trends in PFS vs. OS PFS results that are inconsistent between local and central assessment, or are not yet centrally assessed Co-primary endpoints – OS, PFS, ORR, CR Multiple populations of interest – ITT and a biomarker subgroup Interim analyses – overwhelming efficacy and statistical futility Program-wide DMCs – interpreting trends across multiple studies and logistical details Safety assessment in a study with thousands of AEs – novel graphics and tables Laboratory values and vital signs – novel graphics and tables Multiple comparisons and/or multiple p-values Non-standard tables, listings, figures that are particularly useful for DMC review Open-label studies – immediate withdrawals for those randomized to control arm and other potential biases Single-arm studies – how to interpret safety with no control arm Novel therapies – immune-oncology, CAR-T, small sample sizes CIOMS reports or patient narratives Conclusions: DMCs will perform a more thorough and efficient review of accumulating data upon adapting the guidance provided. A more thorough review will enhance the protection of the trial participants while a more efficient review will allow DMCs to focus their efforts appropriately." @default.
