Nutrition and Exercise in Critical Illness (The NEXIS Trial): A Randomized Trial of Combined Cycle Ergometry and Amino Acids in the ICU

Clinical Evaluation Research Unit at Kingston General Hospital·interventional·Posted Jan 16, 2017·Updated Aug 27, 2025

In Brief

A Phase 2 clinical trial evaluating IV amino acids and In-bed cycle ergometry exercise for Acute Respiratory Failure. Completed, enrolled 115 participants across 7 sites.

Detailed Summary

This study proposes a novel early intervention combining Intravenous (IV) amino acids plus in-bed cycle ergometry exercise to improve physical outcomes in critically ill patients. The investigators hypothesize that this innovative approach will improve short-term physical functioning outcomes (primary outcome), as well as amino acid metabolism, body composition, and patient-reported outcomes at 6-month follow-up.

Interventions

IV amino acidsdrug

IV amino acids delivered by continuous infusion, such that the total enteral and IV protein will be between 2.0-2.5 g/kg/day as a combination of amino acid infusion plus standard feeding.

In-bed cycle ergometry exercisedevice

In-bed cycle ergometry exercise delivered in 45-minute sessions once-daily 5 days per week according to a detailed specific protocol that includes a safety check in combination with vigorous verbal encouragement from trained research staff delivering the intervention to promote active cycling. Cycling is protocolized to provide graduated increases in resistance during each session and between daily sessions. Cycling will continue through ICU discharge or 21 calendar days after randomization. The intervention will specifically occur during ICU stay.
