TQT Studies/Intensive QT Study

Cardiac safety must be a top priority when you develop new drugs.
Therefore, in order to make the go / no-go decision before investigating larger studies, it is always a good idea to test QT intervals for investigational drugs at an early stage of drug development.

We have successfully conducted 50 intensive QT studies including 6 TQT studies as Phase 1 clinical studies as of Feb 2017.

One of our biggest advantages is the fact that we have 4 top certified cardiologists that are working closely on TQT studies in compliance with ICH E14 Guidance requirements.

For those IPs that show unique profiles, complimentary consultation of TQT/Intensive QT study design is available.
