Late-Breaking Science preview: Wednesday, Nov. 15


 

 

The final Late-Breaking Science session delves into innovative therapies and novel applications, including two phase 1-2 stem cell trials, an early trial in toxin treatments to prevent atrial fibrillation, a phase 1 test of an interatrial shunt device for heart failure with preserved ejection fraction, and more:

  • TNT-POAF: Nathan Waldron, MD, of Duke University, Durham, N.C., will present results of a trial aiming to prevent postoperative atrial fibrillation with the use of temporary toxin treatment.
  • REDUCE LAP–HF 1: In what the investigators call the first randomized controlled trial of a device-based therapy to reduce left atrial pressure in HFpEF, an inter-atrial shunt device designed to provide continuous and dynamic decompression of the left atrium. Sanjiv J Shah, MD, of Northwestern University will present the study, which holds the hypothesis that the device may reduce symptoms and slow the progression of heart failure.
  • PROPEL: This study tested the hypothesis that granulocyte-macrophage colony-stimulating factor (GM-CSF) combined with supervised treadmill exercise in patients with peripheral artery disease would significantly improve functional performance more than GM-CSF alone or supervised treadmill exercise alone. Mary McDermott, MD, of Northwestern University, Chicago, will present the primary endpoint of change in 6-minute walk performance at 12-weeks’ follow-up, as well as several secondary outcomes.
  • ALLSTAR: Timothy Henry, MD, of the Cedars-Sinai Heart Institute, Los Angeles, will present the phase 1-2 ALLSTAR (Allogeneic Heart Stem Cells to Achieve Myocardial Regeneration) study, which compared allogeneic cardiosphere-derived cells (CAP-1002) to placebo in order to find whether it is safe and effective in decreasing infarct size in patients with an MI.
  • HOPE-Duchenne: This phase 1-2 study randomized men with cardiomyopathy secondary to Duchenne muscular dystrophy to receive CAP-1002 cells or usual care; its primary outcome is safety. Ronald Victor, MD, will present the results.
