Today, @lifebiosciences confirmed the first patient has been dosed with an epigenetic restoration drug candidate. An exciting milestone 🚀 Life Biosciences is the OG cellular rejuvenation using epigenetic restoration to reverse diseases of aging. It was cofounded by @davidasinclair, who serves as Chairman The company’s proprietary Epigenetic Restoration platform utilizes three transcription factors, OCT4, SOX2, and KLF4 (OSK), to restore older and damaged cells to a younger and healthier state. This innovative approach targets a root cause of aging at the epigenetic level, and has the potential to address a wide range of serious age-related diseases The Phase 1 trial will evaluate the safety and tolerability of ER-100, with additional endpoints assessing visual function. ER‑100 is the first clinical candidate from Life Bio’s Epigenetic Restoration platform, which uses controlled expression of three transcription factors, OCT4, SOX2 and KLF4 (OSK) to restore cellular function by resetting the epigenetic code to more youthful patterns of gene expression “This is an important moment for Life Bio and for the field of aging biology,” said David Sinclair, Ph.D., Co‑founder of Life Biosciences and Professor of Genetics at Harvard Medical School. “Our research has suggested that aging is driven in large part by the loss of epigenetic information, not irreversible damage. This clinical study represents the first opportunity to test whether restoring that information can ameliorate human disease.” Beyond ER-100, the company is strategically broadening its therapeutic pipeline to address additional age-related diseases, underscoring the platform’s versatility and transformative potential. “This milestone reflects years of rigorous scientific development and translational research,” said Sharon Rosenzweig‑Lipson, Ph.D., Chief Scientific Officer of Life Biosciences. “Our preclinical studies have demonstrated that controlled OSK expression can reset epigenetic patterns associated with healthy cellular function, improve tissue performance, and restore visual function in animal models. Advancing ER‑100 into the clinic is an important step toward translating epigenetic restoration into a new class of medicines for age-related diseases.” Optic neuropathies represent a large unmet medical need. Current treatments primarily address risk factors, such as intraocular pressure in glaucoma, but do not directly target the damage to retinal ganglion cells. As a consequence, the disease often leads to irreversible vision loss despite treatment Vision loss not only directly impacts patients’ lives, but also increases the risk of loss of independence, damaging falls, and depression and dementia due to social isolation, underscoring the need for disease-modifying therapies. Beyond ER‑100, Life Bio is developing applications of its proprietary Epigenetic Restoration platform for multiple indications in a variety of organs, reflecting the broad therapeutic potential of this platform. About Optic Neuropathies Optic neuropathies are a group of disorders characterized by damage to retinal ganglion cells (RGCs), the primary neurons connecting the eye to the brain. Because RGCs do not naturally regenerate, damage results in permanent vision impairment. One such optic neuropathy, open-angle glaucoma (OAG) is a chronic neurodegenerative disease and a leading cause of blindness in older adults While often associated with elevated intraocular pressure, disease progression frequently continues despite treatment, and some patients suffer from OAG despite normal intraocular pressure. Non-arteritic anterior ischemic optic neuropathy (NAION) is the most common acute optic neuropathy in adults over fifty. It involves sudden, painless vision loss due to insufficient blood flow, for which there are currently no approved treatments About ER-100 ER‑100 is an investigational therapy in clinical development for the treatment of optic neuropathies including OAG and NAION. ER‑100 is designed to restore function in retinal ganglion cells using Life Biosciences’ Epigenetic Restoration platform, which utilizes controlled expression of three transcription factors, OCT4, SOX2 and KLF4 (OSK), to reset cellular gene expression patterns and restore cells to a more youthful and functional state. ER‑100 is currently being evaluated in a Phase 1 clinical trial.

Two days ago, something happened that most of the world still doesn't know about. A human being received the first therapy in history designed to reverse cellular aging inside their body. Not slow it down. Not manage the symptoms. Actually reset the biological clock at the cellular level. @lifebiosciences — co-founded by Harvard geneticist @davidasinclair — announced on June 9 that the first patient was dosed in their Phase 1 clinical trial of ER-100. Let me explain what this actually is, because the implications extend far beyond the eye they're treating. Your DNA is mostly intact throughout your life. Think of it as hardware. What degrades is the epigenome — the layer of chemical instructions that tells your genes what to do and when. Over decades, those instructions get corrupted. Genes that should be active go silent. Genes that should be silent activate. Cells lose their identity and function. We call this aging. ER-100 uses three transcription factors — OCT4, SOX2, and KLF4 — to perform a partial epigenetic reset. These are the same factors that can reprogram any adult cell back into a stem cell. But they're not going that far. They're doing just enough to make damaged cells function like younger versions of themselves — without losing their identity. The delivery is elegant. A one-time injection into the eye. An oral pill acts as an on/off switch — doctors control exactly how long the reprogramming lasts. If anything goes wrong, they turn it off. This didn't come from nowhere. In 2020, Sinclair's team restored vision in old mice and mice with glaucoma using this approach. The paper made the cover of Nature. They moved to monkeys with optic nerve damage — and successfully restored function with no major safety issues. Now, two days ago: the first human. The trial is targeting glaucoma and NAION — a sudden "stroke of the eye" that causes devastating vision loss. Current treatments for both can only slow progression. Nothing reverses the damage. This therapy aims to regenerate damaged optic nerve cells by making them young again. As a cardiologist, here's why this keeps me up at night — in the best possible way. The eye is a safe, measurable starting point. But the platform technology isn't limited to the eye. If partial epigenetic reprogramming works safely in optic nerve cells, the same approach could theoretically be adapted for the brain, the spinal cord, the heart, the liver, the kidneys — any organ where cells lose function with age. We're not testing whether we can treat one disease. We're testing whether we can treat aging itself as a reversible biological process. For my entire career, cardiology has been magnificent at managing the downstream consequences of aging: high blood pressure, plaque buildup, heart failure, arrhythmias, stiffened arteries. We prescribe statins, antihypertensives, anticoagulants, and devices to manage what time does to the cardiovascular system. We're getting better every year. But what if the cells themselves could be reset? What if the cardiac muscle cells that lose contractile function with age could be epigenetically restored? What if the endothelial cells lining sixty thousand miles of blood vessels could be made to behave like they did decades earlier? That's not in a trial yet. But the foundational technology just entered a human body for the first time. And the companies racing in this space — Life Biosciences, Altos Labs, NewLimit — are backed by billions of dollars and some of the best scientists alive. Essential caveats — because I'm a physician, not a hype man. This is Phase 1. Roughly 18 patients. The primary goal is safety: does this cause harm? Is it tolerable? Efficacy data will come later. Many promising therapies have failed in the gap between animal models and human reality. Gene therapy carries risks — immune reactions, off-target effects, unintended cellular behavior. The oral on/off switch is a critical safety feature, but this is still the earliest possible stage of testing. No one is reversing aging tomorrow. No one is living to 200 next year. But a line was crossed two days ago that cannot be uncrossed. For the first time in human history, someone received a therapy specifically designed to make damaged cells young again inside a living person. From impossible in theory to proven in mice to tested in monkeys to injected into a human being — in six years. I've spent twenty years treating the consequences of aging. I've held hearts that were failing because time had degraded the cells beyond recovery. I've watched patients lose vision, cognition, mobility, and independence — and told them there was nothing I could do to reverse what time had taken. This week, the conversation began to change. Gene editing to permanently lower cholesterol. Personalized mRNA vaccines to hunt cancer. GLP-1 drugs rewiring metabolism, reducing depression, and cutting cancer metastasis. And now — partial cellular reprogramming to reverse aging at the epigenetic level. I said months ago on this platform that our children may live past 100 — not frail, but strong and vibrant. The evidence keeps building that this isn't optimism. It's a timeline.

Generation Z has the lowest levels of interpersonal trust of any generation we've ever polled. And although the data is time limited, the velocity of their decline in trust already far exceeds any previous generation.

Russia just committed $26 billion to anti-aging research and made longevity a national priority. Welcome to the longevity arms race!

the most important things never announce themselves. electricity didn't send a press release either

it's insane to me that this isn't all over mainstream media right now. for the first time in human history, a drug built to reverse aging was just put into a living person a company called Life Biosciences dosed the first patient in their trial for something called ER-100 it comes from a Harvard geneticist named David Sinclair his theory is that aging comes from your cells losing track of how to read their own DNA think of it like a computer. the hardware is fine, but the software slowly gets corrupted over the years, so the machine runs slower and slower until it stops the instructions for a young, healthy cell are all still in there. your cells just lost access to them over time so this drug does one thing: it reboots the cell back to the version of itself that knew how to run properly they pull it off with three proteins that reset a cell to a younger state and they proved it works before ever touching a human first they restored vision in old mice. then they restored vision in monkeys with optic nerve damage, with no tumors and no signs of harm so now they're testing it on people going blind from glaucoma and a nerve condition called NAION they started with the eye on purpose. it's the cleanest place to test the idea, because they can inject it into one eye without it reaching the rest of the body, the cells there don't heal on their own so any improvement clearly came from the drug, and they can measure vision right down to the letters on a chart the reset happens at the level of the cell, so in theory the same approach could one day rejuvenate the liver, the kidneys, even the brain it won't be automatic though. every organ needs its own way of getting the drug into the right cells, plus its own round of safety testing. so it doesn't suddenly work everywhere the moment it works in the eye but the eye answers the one question nobody could answer before: whether you can safely turn back the age of living cells inside a person if the answer is yes, reaching the rest of the body comes down to delivery, one organ at a time. that part is hard, but it's the kind of hard you can engineer your way through to be clear, this is an early safety trial. 18 people, 5 year follow up. so nobody is gonna cure aging by next year but if it works, we'll look back at this week as the moment the clock started running backwards for the first time

Healthy aging and muscle function are positively associated with NAD abundance in humans “… conversely, exercise-trained older individuals had NAD levels that were more similar to those found in younger individuals. NAD abundance positively correlated with average number of steps per day and mitochondrial and muscle functioning..” nature.com/articles/s43587-0…
