JCR Pharmaceuticals Presents Preclinical Gene Therapy Data that Demonstrate Promising CNS Uptake at American Society of Gene and Cell Therapy
HYOGO, Japan--(BUSINESS WIRE)-- JCR Pharmaceuticals Co., Ltd. (TSE 4552; 'JCR') announced today that the Company presented preclinical data from its novel adeno-associated virus (AAV) gene therapy research programs at the American Society of Gene and Cell Therapy (ASGCT) 28 th Annual Meeting, being held May 13-17, 2025, in New Orleans, LA. In an oral presentation, the JCR researcher reported that the Company's proprietary J-Brain Cargo ® (JBC) technology enables the efficient delivery of an adeno-associated virus (AAV) gene therapy across the blood-brain barrier (BBB) and into the central nervous system (CNS) in mice, monkeys, and several animal models of CNS diseases. We have successfully developed JUST-AAV, a novel AAV vector platform technology designed to enhance targeted delivery and reduce liver tropism, thereby improving safety and efficacy of AAV-based gene delivery technologies to the CNS. JUST-AAV encompasses a range of vector types optimized for various target tissues, including liver-sparing, muscle-targeting, and brain-targeting variants. This proprietary technology holds significant promise for advancing the field of AAV-based gene therapy. 'These findings represent a significant advancement toward new treatments for previously challenging CNS diseases,' said Hiroyuki Sonoda, Ph.D., Director, Senior Managing Executive Officer, and Executive Director, Research Division at JCR Pharmaceuticals. 'Our preclinical data demonstrate that our brain-targeting JUST-AAV technology delivers therapeutic agents to the central nervous system far more efficiently than conventional AAV9, while significantly reducing liver accumulation. This enhanced safety profile greatly increases the potential for clinical translation. This research is a crucial step in our ongoing commitment to developing innovative solutions for unmet medical needs.' JCR showcased the following presentation: Incorporation of transferrin receptor binder and surface mutations into AAV enables efficient brain delivery and reduced liver tropism Presenter: Yuhei Ashida (JCR Pharmaceuticals) Researchers successfully created a brain-targeting AAV vector (brain-targeting JUST-AAV) by incorporating a miniaturized antibody that binds to the transferrin receptor, into the AAV capsid. Furthermore, unique modifications to the AAV capsid sequence significantly reduced AAV vector accumulation in the liver, a known source of adverse effects. In mouse studies, the JUST-AAV vector achieved 77-fold higher expression of green fluorescent protein (GFP) in the brain compared to AAV9, while reducing the tropism to the liver by 99%. To further enhance brain targeting and BBB permeability, the researchers incorporated additional molecules that bind to receptors other than the transferrin receptor into the AAV capsid. In monkey studies, this bispecific vector demonstrated an improved gene delivery efficiency to the brain by several orders of magnitude compared with AAV9, while reducing infection in potentially problematic tissues such as the liver and dorsal root ganglia by more than 90%. Application of JUST-AAV to a mouse model of neuronal ceroid lipofuscinosis resulted in the disappearance of symptoms such as seizures and prolonged lifespan to an extent of a functional cure. These results suggest that the newly developed JUST-AAV technology offers the potential for safer and more efficient gene therapy than conventional gene delivery vectors.

For more information, please visit www. About the J-Brain Cargo ® Platform Technology JCR Pharmaceuticals has developed a proprietary blood-brain barrier (BBB)-penetrating technology, J-Brain Cargo ®, to bring biotherapeutics into the central nervous system (CNS). The first drug developed based on this technology is IZCARGO ® (INN: pabinafusp alfa) and was approved in Japan for the treatment of a lysosomal storage disorder. JUST-AAV JUST-AAV is a proprietary platform technology that utilizes modified adeno-associated virus (AAV) vectors. The technology entails insertion of miniaturized antibodies against receptors on selected tissues, organs or the blood-brain barrier onto the capsid surface, enhancing targeted delivery to those tissues and organs. Further capsid modifications minimize off-target effects and improve safety. The name is derived from ' J CR' ' U ltimate destination of organ' ' S afeguarding against off-target delivery' and ' T ransformative technology' reflecting its potential for broad application across various diseases.
