Data replicate and expand upon the potential of ER-100 to improve retinal ganglion cell function and restore visual function in a nonhuman primate model of nonarteritic anterior ischemic optic neuropathy (NAION)BOSTON, Oct. 21, 2024 (GLOBE NEWSWIRE) -- Life Biosciences (“Life Bio”), a biotechnology company advancing innovative cellular rejuvenation technologies to reverse diseases of aging and injury and ultimately restore health for patients, today announced new data presented at the 2024 American Association of Ophthalmology (AAO) Annual Meeting that took place in Chicago, Illinois from October 18-21, 2024. Results replicate previously reported nonhuman primate (NHP) data and further expand our knowledge on dosing and timing of treatment. ER-100, a novel partial epigenetic reprogramming gene therapy containing Oct-4, Sox-2 and Klf-4 (OSK), was administered via a single intravitreal injection along with daily systemic doxycycline to NHPs with a NAION-like injury. Immunohistochemistry confirmed expression of each transcription factor (Oct-4, Sox-2 and Klf-4) in discrete cells in the perifoveal regions in ER-100 treated NHPs relative to vehicle. Furthermore, ER-100 significantly reduced deficits in pattern electroretinogram and axon density measures when administered in both prevention and rescue paradigms. Collectively, these results demonstrate that ER-100 successfully targets retinal ganglion cells and reduces the loss of visual function in an NHP model of NAION. Life Bio remains on track to initiate the first human clinical study evaluating ER-100 for optic neuropathies in the second half of 2025. “Partial epigenetic reprogramming has the potential to restore visual function for those with optic neuropathies such as NAION and glaucoma,” said Sharon Rosenzweig-Lipson, Ph.D., Chief Scientific Officer of Life Bio. “The data shared today replicate and build upon our understanding of the dosing of ER-100 and the timing of the treatment window relative to the onset of NAION-related damage. We look forward to advancing this program toward human clinical trials next year for patients affected by these age-related optic neuropathies.” About Life Biosciences Life Biosciences is a biotechnology company advancing innovative cellular rejuvenation platforms to reverse diseases of aging and injury and ultimately restore health for patients. The company is focusing on two platforms targeting key mechanisms underlying aging biology, epigenetic reprogramming and chaperone-mediated autophagy, to restore cells to a more youthful state. Therapies developed within these platforms have the potential to prevent, treat, and/or reverse multiple aging-related diseases.

SAN DIEGO--(BUSINESS WIRE)-- Rejuvenate Bio today announced publication of groundbreaking research in the peer-reviewed journal Cellular Reprogramming. The study, titled "Gene Therapy-Mediated Partial Reprogramming Extends Lifespan and Reverses Age-Related Changes in Aged Mice," reveals promising advancements in combating age-related diseases and extending lifespan through cellular rejuvenation. Aging is a complex process characterized by cellular dysregulation leading to deteriorated tissue and organ function. While aging cannot be prevented, interventions targeting cellular processes offer potential for mitigating its impact on health and lifespan in the elderly. Rejuvenate Bio's research focuses on partial reprogramming using the Yamanaka factors, specifically OCT4, SOX2, and KLF4 (OSK), to reverse age-related changes. In this study, systemically delivered adeno-associated viruses (AAVs) encoding an inducible OSK system were administered to 124-week-old male mice, equivalent to approximately 77 human years. The results demonstrated a remarkable 109% increase in median remaining lifespan compared to wild-type controls, along with improvements in various health parameters. Notably, frailty scores showed significant enhancements, indicating improved healthspan in treated mice. The active group also reported significant age-reversal in heart and liver tissues, as well as human keratinocytes, as indicated by DNA methylation clocks. To understand how OSK overexpression impacts human cells, OSK was also introduced into HEK001 keratinocytes obtained from a 65-year-old male patient's scalp. The researchers observed significant epigenetic age reversal in the treated keratinocytes compared to untreated or GFP-transduced cells. These findings, along with the data from mice, indicate that AAV-mediated gene therapy delivering OSK extends lifespan in mice while enhancing health parameters and reverses aging biomarkers in both mouse and human cells. “For the first time, we extend median remaining lifespan in extremely old wild-type mice, accompanied by improved health outcomes via systemic AAV-based partial reprogramming therapy,” said Noah Davidsohn, Ph.D., Chief Scientific Officer, Rejuvenate Bio. “Our study demonstrates profound age reversal in wild-type mice through exogenous OSK expression, evidenced by restoration of genomic methylation patterns characteristic of younger cells—a validated hallmark of age reversal. Our approach could potentially address the growing burden of age-related diseases in human populations, and we look forward to translating our findings into potential therapeutic interventions for aging-related conditions.” “This is the first published work to actually have epigenetic reprogramming extend overall lifespan in normal mice,” said Dan Oliver, Ph.D., CEO, Rejuvenate Bio. “The study’s analysis of human keratinocytes expressing exogenous OSK also revealed significant epigenetic markers of age reversal, suggesting a potential restoration of genetic networks to a younger, healthier state. These results may have important implications for the development of partial reprogramming interventions to reverse age-associated diseases in the elderly population.” About Rejuvenate Bio Rejuvenate Bio is a biotechnology company dedicated to developing novel gene therapies for chronic age-related diseases.
