Protein-enriched peripheral IV nutrition after gastric cancer surgery

The PROGAIN Trial : A Randomized Study of Protein-enriched Parenteral Nutrition on Nitrogen Balance and Recovery in Perioperative Gastric Cancer Surgery

Phase 3 Interventional Soonchunhyang University Hospital · NCT07488611

This tests whether giving protein-enriched peripheral IV nutrition around the time of surgery helps adults recover faster after gastrectomy for stomach cancer.

What this trial studies

This randomized Phase 3 trial assigns adults undergoing gastrectomy for gastric cancer to receive either a protein-enriched peripheral parenteral nutrition formulation (Winuf A+ injection) or standard peripheral parenteral nutrition (Winuf injection) during the perioperative period. The primary outcome is nitrogen balance on postoperative day 5, and secondary outcomes include postoperative complications, time to recovery of oral intake, and short-term changes in nutritional status and body composition. The approach aims to bridge early postoperative nutritional gaps without central venous access by using higher-protein peripheral formulations that overcome osmolarity limits of traditional PPN. Investigators hypothesize that protein-enriched PPN will better blunt postoperative catabolism and reduce early muscle loss compared with standard PPN.

Who should consider this trial

Good fit: Adults aged 19 or older scheduled for gastrectomy for gastric cancer who can give informed consent and do not have uncontrolled severe systemic disease or excluded metabolic abnormalities are the intended participants.

Not a fit: Patients with uncontrolled severe systemic disease, significant metabolic abnormalities, recent intravenous parenteral nutrition, or those not undergoing gastrectomy are unlikely to benefit from this intervention.

Why it matters

Potential benefit: If successful, patients might maintain better nitrogen balance, lose less muscle, and regain oral intake and function sooner after gastrectomy.

How similar studies have performed: While adequate perioperative protein delivery is known to support recovery after major surgery, protein-enriched peripheral parenteral formulations are recently developed and lack large Phase 3 evidence, so this approach is relatively novel.
