Dibifree, a dietary phytomix add-on therapy, significantly reduced HbA1c, fasting and postprandial glucose, and body fat percentage in T2D patients, with mechanistic evidence supporting multi-target actions across the gut-pancreas-adipose-immune axis.
Key Findings
Results
Dibifree as add-on therapy significantly reduced HbA1c compared with placebo in a randomized controlled trial.
Study design: 7-month randomized, double-blind, placebo-controlled crossover trial with 40 adults with T2D.
Dibifree was administered at 15 g/day as add-on therapy for two 3-month sessions separated by a 1-month wash-out.
HbA1c was a primary endpoint and was significantly reduced compared to placebo.
Effects were sustained after wash-out and upon re-challenge with Dibifree.
Results
Dibifree significantly reduced fasting and postprandial glucose compared with placebo.
Fasting glucose and postprandial glucose were both primary endpoints.
Reductions were statistically significant compared to the placebo arm.
Effects persisted after the wash-out period and were reproduced upon re-challenge.
The crossover design allowed placebo recipients to switch to Dibifree in the second session, providing additional within-subject comparisons.
Results
Dibifree reduced body fat percentage in T2D patients.
Body fat percentage decreased in Dibifree-treated subjects.
Body weight was listed as a primary endpoint alongside glycemic measures.
Reduction in adiposity was consistent with in vitro findings of suppressed adipogenesis.
This was observed in the context of an add-on therapy to existing diabetes treatment.
Results
Transcriptomic profiling of Dibifree-treated cell lines revealed reversal of diabetic gene signatures and enrichment of multiple metabolic pathways.
Pathways enriched included cAMP/GLP-1, insulin secretion, AGE-RAGE, and IL-10 pathways.
Analysis involved transcriptomic profiling of treated cell lines followed by pathway enrichment analyses.
Results indicated a reversal of diabetic gene expression signatures.
These findings provided a mechanistic basis for the multi-target effects of Dibifree.
Results
Dibifree demonstrated enhanced GLP-1 secretion and inhibition of DPP-4 and α-glucosidase in functional assays.
Incretin activity was assessed via in vitro assays showing enhanced GLP-1 secretion.
DPP-4 inhibition was confirmed, which would prolong endogenous GLP-1 activity.
α-glucosidase inhibition was demonstrated, consistent with delayed carbohydrate absorption.
Improved glucose tolerance was also observed in T2D mice in vivo.
Results
Dibifree reduced advanced glycation end-product (AGE) formation in functional assays.
Inhibition of AGE formation was demonstrated in vitro.
This activity corresponded to enrichment of the AGE-RAGE pathway in transcriptomic analyses.
Reduction of AGE formation is relevant to prevention of diabetic complications.
This was one of several multi-target mechanisms identified for Dibifree.
Results
Dibifree suppressed adipogenesis and promoted M2 macrophage polarization in functional assays.
In vitro assays demonstrated suppression of adipogenesis, consistent with the observed reduction in body fat percentage in clinical participants.
Promotion of M2 macrophage polarization was demonstrated, indicating an anti-inflammatory immune modulation effect.
These findings corresponded to IL-10 pathway enrichment in transcriptomic analyses.
These mechanisms were described as relevant to metabolic and immune regulation in T2D.
Background
Dibifree was formulated as a dietary phytomix using food-derived anti-diabetic bioactivities and administered at 15 g/day.
Dibifree was developed by integrating dietary and therapeutic strategies for T2D management.
The dose was 15 g/day administered as add-on therapy to existing treatments.
The product is described as a functional food intervention.
Mechanistic studies used integrated bioinformatics and functional assays to elucidate the basis of its effects.
