Root Cause Analysis for an FDA Complete Response Letter

The FDA asked for a root cause analysis after a pharmaceutical company submitted a new drug, but there were variations in the drug’s Cmax (maximum concentration), driven by about 5% of the test subjects. (See the article describing the issue HERE.)

What could a company do to analyze this problem? First, they could use a tool taught in our 5-Day TapRooT® Advanced Root Cause Analysis Team Leader CourseChange Analysis. They would develop a list of key factors in the Cmax results and compare the 5% of test subjects with low Cmax to the 95% with normal Cmax. This data could be displayed on a SnapCharT of the drug administration process that would help identify the Causal Factors in the variations in Cmax. These Causal Factors would then be analyzed using the TapRooT® Root Cause Tree® Diagram and Root Cause Tree® Dictionary (part of the TapRooT® Software) to identify the root causes of the drugs Cmax variation among various test subjects.
