Inorganic NItrate and EXercise Performance in Heart Failure (iNIX-HF): Dose Response

Washington University School of Medicine·interventional·Posted Jun 13, 2016·Updated May 20, 2025

In Brief

A Phase 2 clinical trial evaluating KNO3, potassium nitrate for Heart Failure. Completed, enrolled 42 participants across 1 site.

Detailed Summary

The purpose of this study is to do the work that is necessary and sufficient for setting up an appropriate multi-center, randomized clinical trial (RCT) of a new therapy for heart failure: inorganic nitrate. The investigators will first determine the effects and palatability of \~12.8mmol KNO3 (an oral pill) as compared to the roughly equivalent amount of nitrate in 2 beetroot juice (BRJ) Sports Shots (by James White Drinks). Next, the investigators will determine the effects of inorganic nitrate (KNO3 in an oral pill format) on blood pressure, blood nitrate levels, breath nitric oxide (NO) levels, and exercise performance in a dose-response study. Third, the investigators will perform a small phase II chronic treatment study that will allow them to determine the best primary endpoint and the numbers of patients the investigators will need to study in the large, multi-center RCT to follow this project. In the small study and in the RCT to follow, the investigators will determine whether inorganic nitrate can improve aerobic exercise capacity, muscle power, and speed of muscle contraction, and lessen the effort of breathing during exercise.

Interventions

KNO3, potassium nitratedrug

Potassium nitrate (KNO3) will be given orally in 2 gelatin capsules, which will be compounded by the Barnes-Jewish Hospital Pharmacy. The doses are 10 mmol and 20 mmol KNO3.
