💬In plain words
What the trial is, and whether it could suit you
The primary objective of the CRAVE feasibility trial is to assess the feasibility of conducting a larger CRAVE platform trial by performing a randomized trial of 30 participants with pulmonary hypertension and right ventricular dysfunction, comparing empagliflozin or ranolazine plus standard of care to standard of care alone.
