Study Type:
Open-label, randomized, single-center proof-of-concept clinical trial
Objective:
To evaluate the immunomodulatory and metabolic effects of Omega-3 polyunsaturated fatty acids (PUFAs) in patients undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT), and to explore their potential in preventing and mitigating acute graft-versus-host disease (aGVHD).
Study Population:
More than 30 patients aged 18-65 years undergoing allo-HSCT.
Intervention:
Daily intravenous infusion of Omega-3 lipid emulsion at 2 mL/kg (equivalent to 0.2 g/kg of fish oil), administered in combination with medium/long-chain fat emulsion, starting from the conditioning regimen until neutrophil and platelet engraftment or up to Day +35.
Primary Endpoint:
Incidence and severity of aGVHD within 100 days post-transplant.
Secondary Endpoints:
Immune reconstitution (changes in T, B, and NK cell subsets) Lipid and metabolic regulation (TC, TG, HDL-C, LDL-C, TBA) Incidence and severity of infections Overall survival (OS) and progression-free survival (PFS)
Statistical Analysis:
Chi-square/Fisher's exact test, Kaplan-Meier survival analysis with log-rank test, multivariate regression, metabolomics and transcriptomics (PCA, PLS-DA), and pathway enrichment and correlation analyses.
Expected Outcome:
Omega-3 supplementation is expected to reduce the incidence and severity of aGVHD by modulating immune responses and metabolic processes, thereby providing a novel preventive strategy for post-transplant complications.
Read the detailed description
This study evaluates the therapeutic potential of Omega-3 polyunsaturated fatty acids (PUFAs) in the context of acute graft-versus-host disease (aGVHD) following allogeneic hematopoietic stem cell transplantation (allo-HSCT).
Omega-3 fatty acids have demonstrated beneficial effects on cardiovascular health, regulation of immune responses, and modulation of inflammatory pathways. Given that current immunosuppressive therapies for aGVHD are often associated with significant side effects and limited efficacy, the development of safer and more effective interventions is urgently needed.
The investigators have previously established robust research platforms, including HTLV-1 detection methods, infection and disease models (such as humanized mice and Diannan small-eared pig models), as well as multi-omics technologies covering virology, immunology, genomics, and epigenetics. Building on this foundation, the present trial aims to:
Conduct integrative analyses of viral genomic characteristics and host genetic susceptibility to construct a risk prediction model for ATL development, providing data support for clinical prevention and treatment strategies.
Characterize the dynamic spatial and temporal changes of the host immune microenvironment at the single-cell level after HTLV-1 infection, and elucidate key nodes of virus-host interaction that contribute to aGVHD pathogenesis.
Establish and optimize therapeutic strategies targeting the NPM1/B23-sHBZ interaction, and evaluate the specificity, efficacy, and safety of Omega-3 PUFA-based immunotherapy alone or in combination with agents such as PD-1 antibodies, chidamide, and DNA methyltransferase inhibitors.
Assess treatment outcomes by monitoring virological suppression, tumor burden, immune and metabolic microenvironment alterations, epigenetic modifications, incidence and severity of cytokine release syndrome (CRS), hematological parameters, and overall survival.
This proof-of-concept study is expected to provide important scientific evidence for the development of novel immunotherapy approaches targeting ATL, with the potential to improve prognosis and expand therapeutic options for patients undergoing allo-HSCT.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Omega-3 Lipid EmulsionDrug
Also called ω-3 Lipid Emulsion, Omega-3 PUFA, Omega-3 Fatty Acid Emulsion
Intravenous Omega-3 lipid emulsion administered at a dose of 2 mL/kg/day (equivalent to 0.2 g/kg of fish oil), starting from the conditioning phase prior to hematopoietic stem cell infusion and continuing daily until neutrophil and platelet engraftment or up to Day +35 post-transplantation. The emulsion is infused over 4-6 hours and combined with medium- and long-chain triglyceride emulsion as part of parenteral nutrition.
| Study group | Role | What they receive |
|---|---|---|
| Omega-3 Lipid Emulsion Group | Experimental | Participants in this arm will receive standard post-transplant care plus intravenous Omega-3 lipid emulsion at a dose of 2 mL/kg/day (equivalent to 0.2 g/kg of fish oil). The infusion will begin during the conditioning phase and continue daily until neutrophil and platelet engraftment or up to Day +35 post-transplantation. Receives: Drug: Omega-3 Lipid Emulsion |
| No Intervention | No intervention | Participants in this arm will receive standard post-transplant care as per institutional protocol. No Omega-3 lipid emulsion or additional investigational product will be administered. This group serves as the control group for evaluating the effects of Omega-3 supplementation in the experimental arm. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence and Severity of Acute Graft-versus-Host Disease (aGVHD) Within 100 Days After Allogeneic Hematopoietic Stem Cell Transplantation
The primary outcome is to assess the incidence and clinical severity of acute graft-versus-host disease (aGVHD) occurring within 100 days following allogeneic hematopoietic stem cell transplantation. aGVHD will be diagnosed and graded based on standard clinical criteria involving skin, liver, and gastrointestinal tract involvement, using established staging and grading systems.
Measured: Within 100 days post-transplantation
Secondary outcomes (1)
Progression-Free Survival (PFS) at Day 100 Post-Transplantation
Progression-Free Survival (PFS) is defined as the time from transplantation to disease relapse, progression, or death from any cause, whichever occurs first. Participants who are alive and without disease progression at Day 100 will be considered progression-free.
Measured: 100 days post-transplantation

- Model description
- This is a single-center, open-label, randomized, parallel assignment trial. Participants undergoing allogeneic hematopoietic stem cell transplantation (allo-HSCT) will be randomly assigned in a 1:1 ratio to either receive standard care or standard care plus intravenous Omega-3 lipid emulsion. The intervention will continue until hematopoietic engraftment or up to Day +35 post-transplantation. The primary objective is to assess the effect of Omega-3 supplementation on the incidence and severity of acute graft-versus-host disease (aGVHD) within 100 days post-transplant.
