QT Investigations

QT investigation is a crucial component of the clinical development program for most compounds. With over 35 years of experience in supporting clients with these trials, Biotrial’s Core Lab can provide comprehensive assistance at every stage of the project.

Whether this means including a QT investigation component within a phase I program, performing a dedicated Thorough QT (TQT) trial or implementing further measures within various Clinical Pharmacology or phase II-III trials, Biotrial’s Core Lab offers the required expertise.


In addition to designing QT elements of a phase I trial or dedicated TQT trials, Biotrial can assist in the specific Concentration-QT analysis.


Consulting & Design Services

Consulting & Design Services are offered by experts who help design your QT investigation in line with the compound profile & regulatory requirements, whether this requires a specific TQT trial or can be integrated into another clinical protocol.

This includes the interpretation of trial results as well as advice on the overall development plan for the compound.
