Study summary

The goal of this study is to develop a safe, effective, and readily available treatment that will prevent chronic pain following Major Thermal Burn Injury (MThBI). Burn survivors are prone to develop chronic pain and there is an urgent unmet need for preventative treatments. The preventative treatments proposed for this study, Omega-3 Fatty Acids (O3FA) and Vitamin D have been selected given effectiveness across a range of painful musculoskeletal disorders and their wide availability and low cost. This study is a 2x2 factorial, double-blind, placebo-controlled randomized controlled trial test for the effectiveness of O3FA and Vitamin D to prevent chronic pain development. Burn survivors will be enrolled who have experienced thermal burns that cover less than 30% total body surface area that are severe enough to warrant surgical management, which represents the most common burn injury characteristics. Patients will be enrolled within 72 hours of their burn, and randomized via 1:1:1:1 allocation to receive placebo, O3FA, Vitamin D or both. The investigators will obtain blood samples on enrollment and at 6 weeks to assist in elucidating key mechanisms by which O3FA and Vitamin D reduce chronic pain following MThBI. Chronic pain severity, assessed with a 0-10 numeric rating scale at 6 weeks, 3 months, 6 months and 1 year will be entered into a repeated-measures model. Model estimated contrasts will serve as the primary outcome.

Read the detailed description

Patients will be screened daily. Patients who meet eligibility criteria will be approached for participation. Patients interested in participating will proceed through informed consent. Once informed consent is obtained, an initial questionnaire will be administered, a blood draw will be performed to assess for baseline Vitamin D/O3FA concentration and immune profile. Then patients will be randomized into one of 4 treatment arms in 1:1:1:1 allocation. Patients will receive study drug for 6 weeks following burn injury. Adverse event monitoring will occur daily while inpatient and weekly once discharged from the hospital through 6 weeks. Patient compliance with the study drug will be assessed via patient-reported reported missing doses, pill counts at the end of the study, and a 6-week blood draw in which Vitamin D/O3FA levels and immune profile will be assessed. Patient-reported outcomes will be collected via follow-up survey at 6 weeks, 3 months, 6 months, and 1 year following burn injury.s, and 1 year following burn injury.

Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Child-Pugh class

A score of how well the liver works in people with liver disease such as cirrhosis: class A is mild, B moderate and C severe.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

What researchers measure

Primary outcomes

  1. Qualitative Review of Treatment-Related Adverse Events

    A primary objective of this pilot study is to ensure safety of both treatments as well as combined. A qualitative review of treatment-related adverse events will be performed and a determination about the degree of relatedness of each adverse event with the intervention using CTCAE criteria will be made as CTCAE criteria assesses relatedness to therapy. Investigator reviewing the details of each adverse event rated the likelihood of relatedness to the study drug on a scale: (unrelated, unlikely, possible, probably, definitely).

    Time frame: 6 weeks following burn injury

  2. Percent of Participants Who Are Compliant With Follow-up (Feasibility)

    The primary objective of this pilot study is to ensure that the investigators are able to make follow-up assessments on a majority of participants. The percent of participants who are compliant with follow-up will be determined 6 weeks following major thermal burn injury. Feasibility is defined as \>80% of enrolled participants at 6 weeks following Major Thermal Burn Injury (MThBI).

    Time frame: 6 weeks following burn injury

  3. By Group Efficacy Estimates Over Year Following Thermal Burn Injury

    Estimates of efficacy will be obtained via repeated measures analysis of pain severity over the 1 year following injury using mixed effects models. Pain will be assessed using a 0-10 numeric rating scale with 0 indicating no pain and 10 indicating pain as severe as you can imagine. Higher scores represent worse outcome. These values (collected in identical fashion over 1 year following burn injury) will be entered into a linear mixed model, and overall effect estimates (beta coefficients) among groups will be determined. Final model was a piece-wise linear mixed model, with a cut-point at 6 weeks. Mixed models were adjusted for age, sex, race, initial pain severity. Every 1 unit change in beta coefficient represents a 1 unit change in pain severity on the 0-10 numeric rating scale.

    Time frame: Over 1 year following MThBI

Secondary outcomes

  1. Sex Differences in Treatment Response Based on Pain Scores

    Examines existence of gender-based treatment response differences in pain severity measured by a 0-10 numeric rating scale where 0 is no pain and 10 is the most severe pain. Higher scores reflect greater pain (poor outcome).

    Time frame: 6 weeks following burn injury

  2. General Mental Health as Measured by the Short Form (SF)-12 General Mental Health Component Scores

    Assessment of mental health will be determined by the short form (SF)-12 mental component score. The short form SF-12 Health Survey is a 12-item participant completed questionnaire to measure general health. It includes a mental component score (MCS): ranging from 0 to 100 points. Low values represent a poor health state and high values represent a good mental health.

    Time frame: 6 weeks following burn injury

  3. General Physical Health by Treatment Group Measured by the SF-12 General Physical Health Component Scores

    Assessment of physical health will be determined by the SF-12 physical component score. The SF-12 Health Survey is a 12 item participant completed questionnaire to measure general health. It includes a physical component score (PCS): ranging from 0 to 100 points. Low values represent a poor physical health and high values represent a good physical health.

    Time frame: 6 weeks following burn injury

  4. Pain Interference by Treatment Group Measured by the Brief Pain Inventory

    The degree to which pain interferes with important life function will be determined by the Brief Pain Inventory. This is a validated, self-reported scale that measures the severity of pain based on the average pain experienced and assesses impact of pain across 7 domains of life function (e.g., enjoyment of life, relationships, normal work). The total severity scores range from 0 (no interference) to 70 (maximum interference). Higher scores reflect greater pain interference.

    Time frame: 6 weeks following burn injury

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 8, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
