Statistical issues in first-in-human studies on BIA 10-2474: Neglected comparison of protocol against practice

01 Sep 2017

By setting the regulatory-approved protocol for a suite of first-in-human studies on BIA 10-2474 against the subsequent French investigations, we highlight six key design and statistical issues which reinforce recommendations by a Royal Statistical Society Working Party which were made in the aftermath of cytokine release storm in six healthy volunteers in the UK in 2006. The 6 issues are dose determination, availability of pharmacokinetic results, dosing interval, stopping rules, appraisal by safety committee, and clear algorithm required if combining approvals for single and multiple ascending dose studies.
