Company Description
Klotho Neurosciences, Inc. (NASDAQ: KLTO) is a U.S.-based biogenetics and biotechnology company in the healthcare sector. According to the company’s public disclosures, Klotho focuses on the development of disease-modifying cell and gene therapies that use a protein derived from a patented form of the human “anti-aging” Klotho gene, often referred to as s-KL. Its work centers on neurodegenerative and age-related disorders, positioning the Klotho gene and related pathways at the core of its therapeutic strategy.
The company describes itself as advancing Klotho-based therapeutics for neurodegenerative diseases such as amyotrophic lateral sclerosis (ALS), Alzheimer’s disease, and Parkinson’s disease, and more broadly as pursuing technologies that support healthy brain function, organ health, and longevity. Klotho’s portfolio consists of proprietary cell and gene therapy programs that use DNA and RNA as therapeutics, together with genomics-based diagnostic assays. These programs are designed around a protein derived from a patented form of the Klotho gene and novel delivery systems intended to transform and improve treatment of neurodegenerative and age-related disorders.
Focus on the Klotho “anti-aging” gene
The company highlights the human Klotho gene as strongly linked to aging and longevity. Public statements note that Klotho levels decline with age and that this decline is associated with age-related disorders such as cardiometabolic disease, neurodegeneration, cancer, sarcopenia (muscle wasting), osteoporosis, and general fatigue. Silencing of the Klotho gene has been described by the company as accelerating multi-organ deterioration. Klotho emphasizes the role of alpha-Klotho and beta-Klotho proteins, as well as related factors such as FOXO3 and anti-myostatin, in its evaluation of potential longevity indicators.
In company communications, the Klotho gene has been characterized as a “master gene” with pleiotropic actions that modulate cellular pathways including insulin resistance, insulin-like growth factor-1, FOXO3 transcription factors, and Wnt signaling. These pathways are described as contributing to the reduction of inflammatory and mitochondrial oxidative stresses and other cell-damaging mechanisms that can be influenced by alpha-Klotho protein isoforms, including soluble Klotho and secreted-Klotho.
Therapeutic programs and pipeline orientation
Klotho Neurosciences reports that its current portfolio includes proprietary cell and gene therapy programs using DNA and RNA as therapeutics, along with genomics-based diagnostic assays. Public materials reference specific product candidates identified as KLTO-101, KLTO-202, and KLTO-303, which are associated with Alzheimer’s and Parkinson’s diseases, ALS and other motor neuron diseases, and aging-related pathologies, respectively. The company has also referred to KLTO-301 in earlier descriptions of its pipeline.
The company has announced that it has begun manufacturing and development activities for KLTO-101 and KLTO-202 and has highlighted KLTO-202 in particular. Klotho reports that the U.S. Food and Drug Administration has granted Orphan Drug Designation for KLTO-202 for the treatment of ALS, which the company cites as regulatory recognition of the therapeutic potential of its Klotho-based programs for serious unmet medical needs.
Gene therapy manufacturing and partnerships
Klotho Neurosciences has disclosed a partnership with AAVnerGene Inc., a biotechnology company focused on adeno-associated virus (AAV) vector technologies. Under this collaboration, Klotho is using AAVnerGene’s AAV manufacturing and tissue-targeted delivery platforms, including the “AAVone” high-yield single-plasmid AAV production system and the “ATHENA” capsid engineering platform.
According to the company, AAVone is intended to simplify AAV production, increase yield, reduce impurities, shorten development time, and lower manufacturing costs compared to traditional “triple transfection” methods in HEK293 cell lines. The ATHENA platform is described as enabling specific tissue targeting of AAV vectors. Klotho has stated that it plans to use these technologies to manufacture gene therapy product candidates that combine tissue-specific promoters with the Klotho gene, aiming to produce elevated concentrations of Klotho protein in targeted tissues and organs affected by neurologic and neuromuscular diseases.
Expansion beyond neurology and longevity focus
While Klotho’s core programs target brain aging and neurodegenerative diseases such as ALS, Alzheimer’s disease, and Parkinson’s disease, the company has publicly announced that it is evaluating the acquisition of complementary technologies aimed at supporting healthy brain function, organ health, and longevity. It has indicated interest in technologies that could improve muscle strength, bone health, and other longevity indicators, with the stated goal of slowing biological aging and reducing the burden of age-related diseases.
Company communications describe efforts to assemble a team of scientists, clinicians, and business leaders focused on identifying key longevity indicators. These efforts include evaluating genes and proteins such as alpha-Klotho, beta-Klotho, FOXO3, anti-myostatin, and their isoforms. Klotho has also stated that it is exploring additional treatments that could support healthy aging and extend human longevity, building on its proprietary Klotho platform.
Corporate status, listing, and financing
Klotho Neurosciences, Inc. is incorporated in Delaware and identifies itself as an emerging growth company and a smaller reporting company under U.S. securities regulations. Its common stock trades on the Nasdaq Capital Market under the symbol “KLTO”, and its warrants trade under the symbol “KLTOW”, as disclosed in its current reports on Form 8-K.
The company has filed a registration statement on Form S-1 that relates to the potential resale of shares of common stock issuable upon conversion of its Series C Convertible Preferred Stock, as well as shares held by an existing stockholder. The S-1 describes a private placement of Series C Convertible Preferred Stock and indicates that Klotho will not receive proceeds from the resale of common stock by the selling stockholders. Klotho has also disclosed that it has raised financing through preferred stock and other arrangements, and that it has used capital to advance its programs, eliminate debt, and maintain compliance with Nasdaq listing requirements.
In a Form 8-K, the company reported receiving a delinquency notification letter from Nasdaq because its common stock did not maintain a minimum bid price of $1 per share for 30 consecutive business days, as required by Nasdaq Listing Rule 5550(a)(2). Nasdaq granted Klotho a period of 180 calendar days to regain compliance by achieving a closing bid price of at least $1 for a minimum of ten consecutive business days, and the company noted that failure to regain compliance could subject its common stock to delisting.
Strategic direction and partnerships
Klotho Neurosciences has communicated a strategy that includes advancing its Klotho-based therapeutics from preclinical development toward clinical evaluation, expanding its research capabilities, and pursuing complementary technologies and acquisitions in areas related to brain health, organ function, and longevity. The company has highlighted a binding agreement with AAVnerGene for manufacturing KLTO-202, the initiation of manufacturing for KLTO-202, and the launch of a research center in Okinawa, Japan, as steps that strengthen its preclinical research, biomarker development, and operational expertise.
The company has also discussed a prior collaboration with SkyBell that was mutually terminated, after which Klotho retained full global rights to its Klotho programs. It has indicated that it is evaluating complementary longevity-related assets and has referenced a Letter of Intent to acquire select assets from Turn Biotechnologies, Inc., including the ERA epigenetic reprogramming platform and the eTurna RNA delivery system, although it later announced that a separate Letter of Intent with Turn Biotechnologies was allowed to expire after evaluation by its board of directors.
Management and expertise
In its public statements, Klotho Neurosciences emphasizes that it is managed by a team of individuals and advisors who are described as highly experienced in biopharmaceutical product development and commercialization. The company also references key scientific advisors and inventors who have presented research on Klotho gene therapy in ALS, Alzheimer’s disease, and longevity at scientific meetings and conferences focused on Klotho-based therapies and diagnostics.
