Cardiac Safety Assessment

  • An Earlier Look at QT Prolongation

    In December 2014, the news of a technique for assessing QT/QTc from data captured during Phase I clinical trials was shared during the FDA-hosted Cardiac Safety Research Consortium (CSRC) meeting.

    The study by the FDA and CSRC demonstrated that new cardiac technology allows for assessment as early as a First-In-Human trial. The methodology includes a significant increase in ECG data evaluation, use of improved algorithms for cardiac assessment and careful analysis of compound systemic exposure to create a powerful combination of maximal data points in a smaller clinical trial performed as part of a required early stage study.

    Development Advantages

    • Early QT safety assessment of drug candidates
    • Confirmation of preclinical cardiovascular safety findings for more informed development decisions and/or potentially “save” drugs that have tested positive in non-conclusive preclinical screening methods (i.e. Purkinje Fiber, ion channel and HERG assays)
    • De-risk drug candidates by providing a more precise indicator of arrhythmia liability prior to late stage development investment
    • Improved development package for licensing or further in-house development
    • Considerable time and cost savings if TQT waiver can be obtained
  • Experience the Difference

  • Methodology Advantages

    • High Precision QT analysis combined with concentration/effect modeling overcomes the limited semi-automated ECG reading approaches that cannot exclude minor QT effect and insufficient power to overcome variability due to low precision
    • High Precision QT analysis allows for TQT-like statistical power in smaller studies such as Single and Multiple Ascending Dose (SAD/MAD) trials
    • Potential elimination of the traditional TQT study for some drugs if the early trial is scientifically rigorous and adequately designed; provides preparatory information for cases where the TQT study will need to be completed.

    ECG & Holter Evaluation

    • Traditional ECG monitoring
    • High-Precision QT for interval evaluation
    • Industry-validated Dynamic QT beat-to-beat approach for early QT studies performed in traditional Phase I studies
