YouthBio Therapeutics Achieves Major Milestone in Alzheimer’s Research

In a pivotal development for Alzheimer’s treatment, YouthBio Therapeutics has announced that it received favorable feedback from the FDA following an INTERACT meeting regarding their promising therapy, YB002. This biotechnology firm, known for its innovative approach to treating age-related diseases through partial cellular reprogramming, aims to revolutionize Alzheimer’s care with this first-in-class gene therapy.

On September 25, 2025, YouthBio reported the FDA’s affirmation that the existing preclinical data supports YB002’s bioactivity as well as the proposed first-in-human clinical trial for Alzheimer’s patients. This news is a significant boost for the company as they navigate the challenging path of regulatory approval, marking a de-risking event that provides clarity and direction towards clinical applications.

“We are thrilled with this INTERACT outcome,” expressed Yuri Deigin, CEO of YouthBio. The FDA's acknowledgement not only affirms their cost-effective development strategy but also signals the transition from theoretical science to actionable clinical objectives. With this validation, YouthBio is poised to be a pioneer in administering partial cellular reprogramming within the human brain, potentially altering the treatment landscape for Alzheimer's disease.

The therapy, YB002, is built on Nobel Prize-winning science that employs Yamanaka factors—known for their ability to induce pluripotency in cells—to reverse epigenetic changes associated with aging, while still preserving cell identity. This unique approach is designed to rejuvenate gene expression, thereby enhancing cellular functionality and potentially halting or reversing Alzheimer’s disease progression.

Notably, YouthBio’s progress is grounded in substantial scientific research, including work from Dr. Alejandro Ocampo. In preclinical studies, YB002 demonstrated potential in ameliorating cognitive decline in mice, effectively reversing disease-related pathologies, and showing promise in counteracting epigenetic aging. The therapy could potentially rescue memory and learning processes in affected individuals.

Dr. João Pedro de Magalhães, Chief Scientific Officer of YouthBio, articulated the significance of the FDA's recognition, emphasizing that it empowers them to streamline their resources strategically for building a robust IND package, thereby enhancing the prospects of upcoming studies.

As the field of partial reprogramming transitions towards clinical applications, this FDA feedback is heralded as a critical milestone not only for YouthBio but for researchers globally, validating years of rigorous scientific inquiry. Renowned researcher Dr. Alejandro Ocampo noted the significance of this development, indicating the potential for partial reprogramming methodologies to emerge as viable options in clinical settings.

The road ahead for YouthBio involves rigorous Chemistry Manufacturing Controls (CMC) activities and a pilot toxicology study, aiming to finalize study designs leading up to a forthcoming Pre-Investigational New Drug (IND) meeting. This meeting will be crucial for detailing the IND-enabling studies that will ultimately determine YB002’s fate in clinical trials.

In conclusion, YouthBio Therapeutics stands at the forefront of a potentially transformative approach to Alzheimer’s treatment. With the FDA's support illuminating the path forward, the company is gearing up for significant advancements in bringing this groundbreaking therapy from the lab to patients in need. As we witness the real-world implications of genetic therapies evolve, YouthBio’s YB002 could represent a beacon of hope for the millions affected by Alzheimer’s disease and their families.
