QT assessment has a heart-pounding new development

Saturday, August 1, 2015

On December 12, 2014, the news of a technique for reliably assessing QT/QTc from data captured during routinely conducted phase I studies was shared during an FDA-hosted Cardiac Safety Research Consortium meeting.

Over the last decade, QT studies have been conducted for almost all New Chemical Entities (NCEs) exhibiting systemic exposure. At a cost of approximately $2 to $4 million per study, QT studies represent a significant investment and development risk, considering a positive finding can result in onerous late-stage or post-approval commit­ments for safety monitoring. It can also completely end the development of the compound.

The Cardiac Safety Research Consortium-FDA study demon­strated that the new cardiac tech­nology allows this assessment to be conducted as early as during the First-in-Human (FIH) dosing study. These studies are typically adminis­tered to healthy normal volunteers in single doses to small cohorts in an ascending manner with the objec­tives of evaluating safety, tolerability, pharmacokinetics and potential dosing regimen for further studies in patient populations.

The question of the FDA accep­tance of this new paradigm was ad­dressed by Dr. Norman Stockbridge, a director in the Division of Car­diovascular and Renal Products at the FDA. Stockbridge told The Wall Street Journal that “if a pharmaceuti­cal company comes to [him] with results using this type of a methodol­ogy, and the study is well conducted with high-quality electrocardiogram data collection and analysis, [he is] ready to recommend its use in regu­latory decision making today.”

This clear pathway forward is a revolutionary attitude, freeing pharmaceutical companies to evalu­ate their potential therapies earlier in development, provide more product valuation for companies looking for further investment or partnering, and most importantly create an early translation of preclinical cardiac safety studies into viable human data and a safety platform for further clinical trials.
