Klotho Neurosciences, Inc. (KLOTHO) Initiates Manufacturing of KLTO-202 Product Candidate Using AAVnerGene's Platform Technology
NEW YORK, Aug. 12, 2025 /PRNewswire/ -- Klotho Neurosciences, Inc. (Nasdaq: KLTO), announces that it signed a binding agreement to initiate manufacturing and development of its KLTO-202 gene therapy candidate using the AAVnerGene Inc. (AAVnerGene) platform technology. As previously announced, AAVnerGene is an innovation-driven biotech renowned for its transformative technologies in adeno-associated viruses (AAV) manufacturing and tissue-targeted delivery. KLOTHO is a biotechnology company focused on the development of groundbreaking, disease-modifying cell and gene therapies using a human gene and protein derived from its patented form of the "anti-aging" Klotho gene.
Dr. Joseph Sinkule, KLOTHO CEO, stated, "The AAVnerGene technology is a game-changer in manufacturing AAV vectors for intracellular delivery of genes. The initiation of manufacturing is a key milestone in the development of any biotech product, and the manufacturing of gene therapy products presents particular complications. KLOTHO is using AAVnerGene's cutting-edge 'AAVone' platform technology and engineered HEK293 cell line to introduce the plasmid DNA containing our Klotho gene, so that the AAV particles containing our gene are at a higher-than-normal titer concentration, have fewer impurities, and can be optimized and produced faster than the old standard method. We believe that working with AAVnerGene as our development partner has the potential to launch our product candidates into the clinic at a faster pace, lower cost, higher efficacy, and higher purity compared to the current 'triple transfection' manufacturing method."
One of the major challenges facing AAV-vectored gene therapies is the propensity of the AAVs to home in on the liver and induce an inflammatory response that causes life-threatening side effects and even death. AAVnerGene created a series of specific tissue-targeting AAVs developed with its 'ATHENA' platform technology. Using the ATHENA system and tissue-specific targeting of the KLTO gene therapy product candidates containing KLTO's tissue-specific promoters will be proven to be highly beneficial and likely safer than the AAV vectors that traffic to the liver.
AAVnerGene and Complexity of AAV-vectored Cell Lines
Over the past 20 years of gene therapy, investigators and companies used a process called "triple transfection" whereby three DNA plasmids are transfected, or inserted, into the cell line called HEK293. The three plasmids contain sequences of the 'gene-of-interest', Rep/Cap sequences from AAV and 'Helper' sequences from Adenovirus to provide essential viral genes to enable replication and packaging of the AAV. As the HEK293 cells replicate and produce the viral proteins, the HEK293 cells assemble the proteins required to make the AAV particles containing the gene-of-interest inside the AAV particle. This is a complicated, tedious, labor-intensive process requiring optimization that may take several months or a year to complete. AAVnerGene developed a one-plasmid AAV packaging system called "AAVone," which dramatically increased the production efficiency, simplified the process, reduced the impurity, shortened the time and lowered the development cost.
