Intralipid Versus SMOFlipid in HPN Patients


This study will randomize all patients who are new to the Mayo Clinic HPN team to either standard lipid emulsion (Intralipid) or SMOFLipid.

Full Title of Study: “Randomized Prospective Trial Comparing Intralipid Versus SMOFlipid in New HPN Patients.”

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Parallel Assignment
    • Primary Purpose: Supportive Care
    • Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
  • Study Primary Completion Date: November 30, 2021

Detailed Description

Primary aim is to assess the impact to direct bilirubin. Secondary aims will be to assess impact to other liver function studies, metabolic parameters, inflammatory marker, body weight, ability to meet caloric needs through TPN, and ability to obtain appropriate macronutrient composition.


  • Dietary Supplement: SMOFLipid
    • SMOFLipid will be given to HPN patients to assess the benefits or adverse effects compared to Intralipid.
  • Dietary Supplement: Intralipid
    • Intralipid will be given to HPN patients to assess the benefits or adverse effects compared to SMOFlipid

Arms, Groups and Cohorts
