Avalon GloboCare advancing immune cell therapy to treat blood cancers using FLASH-CAR technology

The adaptable FLASH-CAR platform can be used to create personalized cell therapy from a patient’s own cells, as well as off-the-shelf cell therapy from a universal donor

Avalon GloboCare Corp (NASDAQ: AVCO) announced Friday that it is advancing its next-generation immune cell therapy to treat blood cancers using FLASH-CAR technology co-developed with strategic partner Arbele Limited. 

The adaptable FLASH-CAR platform can be used to create personalized cell therapy from a patient’s own cells, as well as off-the-shelf cell therapy from a universal donor.

Currently, the Chimeric Antigen Receptor T (CAR-T) cellular immunotherapy platform is available. It involves a patient’s own T-cells — a type of white blood cell that protects against infections and other diseases including cancer— that are turned into personalized cancer-fighting cells.

The T-cells are removed from the patient, reprogrammed in the lab using a viral vector to target cancer cells, and infused back into the patient as a cancer immunotherapy.

But in contrast to these existing therapies, Avalon said its FLASH-CAR platform uses next-generation CAR technology to modify patients’ T-cells and natural killer (NK) cells using a ribonucleic acid (RNA)-based platform rather than a viral vector. 

Similar to T-cells, NK cells are a type of white blood cell, also able to attack cancer cells, but utilize different mechanisms. By using RNA molecules rather than a viral vector, Avalon’s RNA-based CAR technology is designed to rapidly create personalized CAR therapies in 1 to 2 days compared to the 10- to 14-day bio-manufacturing time necessary to generate currently available CAR-T cellular immunotherapy. 

Avalon said its FLASH-CAR technology is also designed to reprogram the immune cells to hone in on multiple crucial cancer cell targets, called tumor antigens, to potentially achieve superior therapeutic effect. Avoiding the use of viral vectors and complicated bio-processing procedures significantly reduces manufacturing costs, resulting in a more affordable and potentially breakthrough therapy for cancer patients. 

The FLASH-CAR technology can also be used to generate “off-the-shelf,” universal cell therapy that has the potential to reach even more patients.

First FLASH-CAR platform candidate AVA-011

Avalon’s first FLASH-CAR platform candidate, AVA-011, targets both CD19 and CD22 tumor antigens on cancer cells. 

Pre-clinical research on AVA-011, including tumor cytotoxicity studies, has been successfully completed and Avalon said it is immediately entering the process development stage to generate clinical-grade CAR-T and CAR-NK cells for use in human clinical trials. 

Avalon and Arbele have jointly filed for US patents for this RNA-based CAR platform cellular therapy and for other applications.

Avalon expects to begin a first-in-human clinical trial with AVA-011 for the treatment of relapsed or refractory B-cell lymphoblastic leukemia (B-ALL) and non-Hodgkin lymphoma in the first quarter of 2021. The goal is to use AVA-011 as a bridge to bone marrow stem cell transplant therapy, currently the only curative approach for patients with these blood cancers.

“Avalon GloboCare is committed to decreasing the time it takes to deliver cellular immunotherapies to cancer patients, as well as lowering the cost of manufacturing by building on our unique RNA-based CAR platform that does not require using a viral vector,” said CEO Dr David Jin.

“We are accelerating our innovative discovery and development plan, as well as delivering precise clinical execution and leadership in cellular immunotherapy. Our pre-clinical studies are encouraging and we are excited for AVA-011 to enter the clinical development stage, including multi-center clinical trials following completion of process development to generate the cell therapy.”

Arbele CEO John Luk added: “Through this strategic partnership with Avalon GloboCare, we envision an accelerated scientific and clinical development of the RNA-based FLASH-CAR technology platform with great potential to generate 'off-the-shelf' immune effector cell therapies to treat both hematologic and solid malignancies.”

Avalon, based in Freehold, New Jersey, specializes in developing cell-based technologies and is involved in the management of stem-cell banks and clinical laboratories.

The company’s stock recently traded up 10% to $1.99 a share in New York.
