ZyVersa Therapeutics Highlights Data Demonstrating a Critical Need for Therapies to Address Kidney Lipotoxicity to Alleviate Diabetic Kidney Disease (DKD) and Its Progression

• Data show that diabetes-associated metabolic issues lead to kidney lipid accumulation, resulting in inflammation and fibrosis that cause progressive kidney damage and disease progression.
• Earlier data by Kanbay et al (Eur J Clin Invest. 2022) demonstrate that fatty kidney is an independent risk factor for chronic kidney disease (CKD), not just DKD, and reinforce that lipid accumulation promotes release of pro-inflammatory cytokines leading to inflammation, fibrosis, and CKD progression.
• ZyVersa is developing Cholesterol Efflux Mediator™ VAR 200 to mediate removal of damaging excess lipids from the kidneys’ filtration system. VAR 200 directly removes cholesterol and lipids from kidney cells, and it upregulates cholesterol transporters, ABCA1 and ABCG1 for active removal.
• A phase 2a clinical trial in patients with DKD has been initiated and is actively screening patients for enrollment. Future studies are planned for patients with rare kidney diseases, focal segmental glomerulosclerosis (FSGS), VAR 200’s lead indication, and Alport Syndrome.
• The global drug market for kidney diseases was $18 Billion in 2024, with $30 Billion projected by 2034 (Precedence Research).
  
  
  
  

WESTON, Fla., Aug. 14, 2025 (GLOBE NEWSWIRE) -- ZyVersa Therapeutics, Inc. (Nasdaq: ZVSA; “ZyVersa”), a clinical stage specialty biopharmaceutical company developing first-in-class drugs for treatment of patients with renal and inflammatory diseases who have unmet medical needs, highlights key data on the role of lipotoxicity in the development and progression of DKD from a review article, , recently published in Frontiers in Immunology. This article, which summarized 172 papers, demonstrated that under diabetic conditions, kidney cells undergo significant lipid metabolic abnormalities resulting in accumulation of lipids that trigger inflammation and fibrosis leading to DKD progression.

“This large body of evidence from 2 review papers demonstrates the critical need for therapies to treat kidney lipotoxicity, a crucial factor in the pathology of DKD and other kidney diseases, such as FSGS and Alport syndrome,” commented Stephen C. Glover, ZyVersa’s Co-founder, Chairman, CEO, and President. “Currently, over 130,000 patients with kidney disease progress to renal failure each year in the US, and more than 800,000 patients are living with renal failure requiring dialysis or transplant to sustain life. We are hopeful that by alleviating lipotoxicity with Cholesterol Efflux Mediator™ VAR 200, kidney injury and disease progression will be reduced, lowering these statistics and improving patients’ quality of life. The first patient in our VAR 200 Phase 2a trial in patients with DKD is expected to start therapy by end of this quarter, with an initial data read-out in the second half of the year.”

Overview of Key Findings

Metabolic issues associated with diabetes, especially insulin resistance and high blood glucose, lead to abnormal lipid metabolism resulting in kidney lipid accumulation, inflammation, and fibrosis.

Multiple impaired pathways contribute to lipid accumulation:

• Insulin resistance increases release of free fatty acids and uptake by kidney cells
• Activation of fatty acid synthesis pathways leads to excessive lipid production
• Impaired cholesterol efflux (removal) resulting from reduced function of cholesterol transporters, ABCA1 and ABCG1, leads to cholesterol and lipid accumulation
• Impaired fatty acid oxidation, reduces ability to break down and use stored lipids

Of the above pathways, impaired cholesterol efflux is a key factor in DKD pathology. It exacerbates lipid accumulation, especially in podocytes, the key component of the kidney’s filtration system, causing structural damage and impaired filtration resulting in protein leaking into the urine, DKD progression, and ultimately kidney failure, if the lipotoxicity is not addressed.

Lipid overload can trigger an inflammasome-induced inflammatory response in kidney cells. Free fatty acids activate inflammasomes initiating an inflammatory cascade via release of IL-1β. Inflammasome activation also induces upregulation of lipid synthesis-related genes while inhibiting expression of lipid efflux transporters like ABCA1, further increasing lipid accumulation. This creates a vicious cycle, causing continuous decline in renal function and ultimately causes irreversible damage.

Currently, no drugs specifically target kidney lipotoxicity.
