ApoCII amyloidosis, resulting from abnormal organ deposition of toxic fibrillar amyloid proteins, is an ultra-rare condition that mostly affects the kidneys and manifests with protein spillage into the urine (proteinuria) and chronic kidney disease.Despite being treated with standard-of-care renal drug therapy (ACEi, SGLT2, statin, and ezetimibe), the patient authorized by FDA to receive VAR 200 is showing continued kidney disease progression. Because her kidney biopsy demonstrated lipid deposition, the treating physician, Dr. Alessia Fornoni, hypothesized that VAR 200 has potential to alleviate lipid accumulation, proteinuria, and disease progression. This is based on VAR 200’s consistent results across preclinical studies in three different models of kidney disease, and supporting HPβCD clinical data in patients with lysosomal storage and protein deposition disorders, such as Niemann-Pick disease type C.VAR 200, currently in a phase 2a clinical trial for diabetic kidney disease (DKD), was designed to passively and actively reduce renal lipid accumulation to protect against renal injury and fibrosis and improve kidney function.

WESTON, Fla., July 08, 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, is pleased to provide regulatory and product support for FDA-authorized Emergency Compassionate Use of Cholesterol Efflux Mediator™ VAR 200 in a patient with ApoCII amyloidosis. Emergency Compassionate Use, also called Emergency Expanded Access, is a pathway for a patient with a serious or immediately life-threatening disease or condition to gain access to an investigational drug for treatment outside of clinical trials when enrollment criteria are not met or there are no comparable or satisfactory alternative therapy options.

The patient with ApoCII amyloidosis will receive treatment at the University of Miami Peggy and Harold Katz Family Drug Discovery Center under the care of the Center Director, Dr. Alessia Fornoni, Professor of Medicine, University of Miami Miller School of Medicine, and VAR 200 inventor. VAR 200 treatment and monitoring will follow the protocol of the ongoing DKD clinical trial, VAR200-0301 (ClinicalTrials.Gov ID: NCT06489340).

"We are at a time where Precision Medicine offers new tools to endophenotype patients and to identify the molecular signature that allows us to match the right patient to the right drug. The evidence of lipotoxic glomerular injury in this patient is what prompted me to request emergency compassionate use. I am very excited about the opportunity to test the efficacy of VAR 200 for this new indication, as I believe experimental treatment cases like this one will drive further clinical development for other patients as well,” stated Dr. Fornoni.

"We are proud to support Dr. Fornoni’s Emergency Compassionate Use of VAR 200 in her patient with ApoCII amyloidosis who currently has no other effective treatment options. We are hopeful that VAR 200 will help to improve the course of her disease and quality of life,” said Stephen C. Glover, ZyVersa’s Co-founder, Chairman, CEO, and President. "We look forward to learning the effects of VAR 200 on proteinuria in this patient with ApoCII amyloidosis, which in combination with the data from our Phase 2a DKD trial, will support the design of our ongoing VAR 200 clinical development program.”

ABOUT CHOLESTEROL EFFLUX MEDIATOR™ VAR 200

Cholesterol Efflux Mediator™ VAR 200 (2-hydroxypropyl-beta-cyclodextrin, 2HPβCD) is an injectable drug in phase 2 development to ameliorate renal lipid accumulation that damages the kidneys’ filtration system, leading to development and progression of kidney disease. VAR 200 removes excess lipids from the kidney both passively, and actively by upregulation of cholesterol efflux transporters, ABCA1 and ABCG.

Preclinical studies with VAR 200 in animal models of FSGS, Alport syndrome, and diabetic kidney disease demonstrate reduced levels of cholesterol and lipids, protection against renal injury and fibrosis, and improvement in proteinuria. Additional information can be found in the VAR 200 White Paper.

The lead indication for VAR 200 is orphan kidney disease, focal segmental glomerulosclerosis (FSGS). Prior to initiating a Phase 2a trial in patients with FSGS, we are conducting a small Phase 2a trial in patients with diabetic kidney disease, which we expect will provide patient proof-of-concept more quickly than an FSGS study. Alport Syndrome and diabetic kidney disease indications may be pursued based on our indication expansion strategy.
