Avoca’s Consulting Service for Quality Tolerance Limits (QTLs) aims to help sponsors and CROs comply with ICH E6 (R2) by providing study teams with training and support for implementing QTLs.


Why are Quality Tolerance Limits Important?

QTL parameters are absolutely critical to basic trial integrity, patient safety, and the primary endpoint. The goal of a QTL is to detect systemic risks – those that will affect the study and make it very hard to draw the right conclusions from your results. Examples include inclusion/exclusion protocol violations, incomplete/missing endpoint data, and AEs/SAEs of special interest. QTLs need to be proactively defined at the planning level of the trial in coordination with risk assessment activities.

Learn how QTLs fit within an overall quality management system (QMS)
