communication with cdrh
Communication with CDRH
  • How to request a statistical meeting
  • Who to contact?
  • When? Early with pre-IDE and pre-PMA meetings
  • Agreement and Determination Meetings
least burdensome provision and levels of evidence
Least Burdensome Provision and Levels of Evidence
  • At first sight one might think that an historically controlled study is less burdensome than a randomized clinical trial. However, if the historical control cannot be demonstrated to be comparable with the data from the current study, then the study may be not controlled (so no comparison is possible) and another study may need to be launched.
national and international
National and International
  • PhARMA and DIA versus Advamed and MDMA
  • International Conference on Harmonization (ICH) versus Global Harmonization Task Force (GHTF)
  • Organizations with an international presence (DIA vs. Advamed) as well as standards organizations: ISO, CLSI (NCCLS), ASTM, AAMI
  • Few statisticians who are in government regulatory positions outside US (Japan PMDA, UK, Germany) all of whom serve both drugs and devices
other statistical venues
Other Statistical Venues
  • Joint Statistical Meetings
    • 9 device sessions in Minneapolis orchestrated by a committee from industry and CDRH and an organizational meeting
  • Society for Clinical Trials and ENAR
  • Standards organizations
  • Other professional meetings where statistical topics arise
  • Help to plan future meetings
