Navigating Regulatory Biostatistical Requirements | Page 13

Conclusion During clinical trials that require regulatory review and approval, planning in advance helps to avoid issues during study conduct and lengthy regulatory reviews later. However, because no trial goes perfectly as planned, it is important to handle any issues during trial execution and the regulatory submission in a way that creates minimal additional regulatory scrutiny. Clinipace, including the Biostatistics team, has the expertise and technological resources to assist with this process and help the process go as smoothly as possible. During the companion webcast for this eBook, we received several great questions during the Q&A Session. To read the responses, please visit each of the links in the boxes below: Q When planning for the end of phase II analyses, is there a way to get questions about data analyses answered by someone at the FDA? Q Can you discuss further key “operational biases” to avoid? Q What is the best way to present post hoc analyses to the FDA? Q Q Can you briefly highlight statistical considerations for adaptive trial designs? Q Should we choose different alpha spending functions in the interim analysis with the purpose of futility assessment versus efficacy assessment? Q Will you please list some common protocol deviations? Q If you perform an interim futility analysis, will it impact the Type I error if you don’t consider stopping for superiority? A blinded study is running. Based on monitoring of blinded data, additional new analysis not in SAP will be interesting. Please comment if one should revise the SAP and provide rationale to the FDA for change prior to study end or do as post hoc analysis. 13
