CSRC/DIA Think Tank: Enabling Social Listening for Cardiac Safety

Meeting Minutes

Overview: Postmarketing safety surveillance primarily relies on data from spontaneous adverse event reports, medical literature, and observational databases. Potential limitations of these data sources include potential underreporting, lack of geographic diversity, potential of patients’ perspectives being filtered through health care professionals and regulatory agencies, and time lag between event occurrence and discovery.

There is growing interest by safety stakeholders in exploring the use of social media (“social listening”) to supplement established approaches for pharmacovigilance. Health information posted online by patients is often publicly available, and thus represents an untapped source of postmarketing safety data that could supplement data from existing sources of cardiac safety information. The purpose of this think tank is to explore current methods of collecting and evaluating social listening data. Representatives from industry, academia, and the FDA will share their perspectives on the topic of social listening and discuss its potential implications in the field of cardiac safety.

This think tank is hosted by the Cardiac Safety Education Collaborative (CSEC)—a partnership between DIA and the Cardiac Safety Research Consortium (CSRC), an FDA and Duke University public-private partnership. The objective of the CSEC is to advance open dialogue of issues related to cardiac safety that represent barriers to medical product development, or issues that constitute limitations in current regulatory science. This think tank is part of the CSEC Signature Program that will span the course of a year and includes a webinar and various publications.

CSRC/FDA Workshop: The Proarrhythmic Assessment of New Chemical Entities

Description: The ICH E14 clinical guidance has been revised (December 2015) and now enables the use of exposure response (ER) analysis applied to early phase clinical data to provide definitive evidence of the lack of a QT effect of a drug in development. ER analysis has evolved as an increasingly important method to assess a drug’s ECG effects; most drugs that cause concerning QT prolongation do this in direct relation to increasing plasma concentrations. Since the power of ER analysis to exclude small ECG effects is greater than the ‘by timepoint’ analysis, it can be used in early clinical phase studies to provide ECG data with the same level of confidence as from the TQT study. A remaining concern with this approach may however be the lack of a positive control. In TQT studies, the positive control demonstrates that a small QT effect can be detected and thereby provides protection against a false negative result.

This session will discuss ER analysis applied to early phase clinical data with emphasis on whether a positive control is needed and alternative methods to establish the study’s sensitivity in lieu of a pharmacological positive control.

Questions to be addressed:

  • How can exposure response analysis of ECG data from early phase clinical studies be used to detect or exclude clinically relevant effects of a new chemical entity?
  • How can protection against false negative result be provided in lieu of a positive control?
  • Which data do regulators expect to grant a TQT study waiver?

Background – It is well established that drug-induced QT interval prolongation is not always proarrhythmic when multiple ion channels are affected.  The Comprehensive In Vitro Proarrhythmia Assay (CiPA) is being developed to use non-clinical cardiac safety evaluations to directly determine a drug’s proarrhythmic potential, irrespective of effects on the QT interval. As part of CiPA, it will be important to determine if a drug’s effects in humans is similar to what would be expected based on the preclinical ion channel data.
