Exhibit 4.1
AAVone License - Terms of Agreement
Between AAVnerGene Inc. and Klotho Neurosciences, Inc. (“KLTO”)
The License Terms of Agreement and collaboration (the “Agreement”) sets forth the terms of an exclusive license and the activities and deliverables associated with a license for KLTO to utilize the AAVone and potentially the AAVShD platform technologies developed by AAVnerGene. The primary activities are associated with a deliverable related to a product candidate called KLTO-202 which targets amyotrophic lateral sclerosis and other rare motor neuron diseases of mankind.
The core intellectual property of AAVnerGene being licensed to KLTO is critical to the success of KLTO’s product development programs. If the patent applications do not result in a patent being granted and issued, the monetary payments and terms of the yet-to-be-executed “Definitive License Agreement” may be amended by the two parties at some future date.
Part I and Part II of the agreement will ultimately result in Part III, the GMP production of KLTO’s gene therapy candidates designated KLTO-202 and potentially Part IV and Part V. KLTO-101 and a third candidate, KLTO-303, may also be developed once a successful outcome and a collaborative relationship has been shown with KLTO-202.
Part I. AAVone Production Platform License Terms and Scope

Exhibit 99.1
Klotho Neurosciences, Inc. Partners with AAVnerGene Inc.
to Make Klotho’s Gene Therapy Assets.
July 22, 2025 – New York, NY - Cision PR NewsWire – Klotho Neurosciences, Inc. (NASDAQ: KLTO), announced that it is partnering with AAVnerGene Inc. (AAVnerGene), a Rockville, MD-based innovation-driven biotech renowned for its transformative technologies in AAV manufacturing and tissue-targeted delivery.
Dr. Joseph Sinkule, the CEO of KLTO stated “we announced previously that we have been looking for a more efficient, ‘next-generation’ method to manufacture several of our patented gene therapy candidates, and the two platform technologies offered by AAVnerGene will catapult our product candidates into the clinic at a faster pace, at a lower cost, a higher efficacy and purity compared to the current state-of-the-art AAV manufacturing processes. We are talking about KLTO-101 for Alzheimer’s and Parkinson’s diseases, KLTO-202 for ALS and other motor neuron diseases, and KLTO-303 for treatment of ageing-related pathologies resulting in a healthy, extended lifespan. I’m also looking at other complementary longevity-related assets that we may bring into KLTO”.
“AAV gene therapy has been proven to be a revolutionary one-time, life-changing treatment, however it is experiencing some crisis caused by high drug price and high dose-related toxicity.” said Dr. Daozhan Yu, Founder and CEO of AAVnerGene. “We envisioned these bottleneck problems six years ago and AAVnerGene was founded with the mission to solve them. With the two proprietary platforms, we can dramatically drive down the manufacture cost with the AAVone system and the dose required by the highly efficient and specific tissue-targeting AAVs developed with the ATHENA platform. It’s a perfect synergy to partner with Klotho, a neuroscience-driven pathfinder. Neurological disease drug development is always challenging and we need new approaches and mechanisms. Klotho’s data on neuron protection and longevity are very impressive and it holds the potential to treat so many devastating diseases. We are very glad to work with the passionate and highly executive team, and strongly believe that the collaboration can bring more affordable and innovative drugs for patients with rare and common diseases.”
Dr. Joseph Sinkule concluded “Klotho believes AAVnerGene has conceived a process method that is more cost effective, faster to make, has fewer impurities, shows higher efficacy and lower toxicity because of the higher targeted tissue delivery. KLTO hopes to work with AAVnerGene for manufacturing several of our product candidates composed of a tissue-specific promoter driving our Klotho gene to produce the Klotho protein and elevated concentrations of the protein in specific, targeted tissues and organs affected by these neurologic and neuromuscular diseases.”
About AAVnerGene, Inc. AAVnerGene is a creativity-powered biotechnology company pioneering next-generation AAV vector technologies. The company’s proprietary platforms include AAVone, a high-yield, single-plasmid AAV production system that dramatically reduces manufacturing costs, and ATHENA, an advanced capsid engineering platform enabling precise tissue targeting. AAVnerGene is dedicated to delivering affordable, scalable, and precision-engineered gene therapy solutions that accelerate clinical development across diverse therapeutic areas.
