Dr. David Sinclair, co-director of the Paul F. Glenn Center for Biology of Aging Research at Harvard Medical School describes a groundbreaking method that can speed up or reverse the aging of cells in the body—at least in mice._  by [Alice Park](https://time.com/author/alice-park/)  ## Alice Park Senior Correspondent Jun 10, 2023 12:11 AM UTC  Eisai Inc.  by [Alice Park](https://time.com/author/alice-park/)  ## Alice Park Senior Correspondent Jun 10, 2023 12:11 AM UTC A panel of experts who advise the U.S. Food and Drug Administration (FDA) agreed on June 9 that a late-stage study of a drug for Alzheimer’s disease showed that it was beneficial in slowing cognitive decline. Lecanemab (brand name: Leqembi), made by Eisai and Biogen, was granted accelerated FDA approval in Jan. 2023 based on early-stage studies of the drug’s effectiveness, and the companies submitted additional data to support full approval for the drug. The six-member committee’s vote was unanimous that the additional study verified the clinical benefit of lecanemab. If the FDA grants the drug full approval, more patients would have access to it. Currently, not all people who need it can receive it: the Centers for Medicare and Medicaid Services (CMS), which operates Medicare, has said it will not cover the drug for most patients unless it receives full approval. Under accelerated approval, patients can only get the drug if they either pay the out-of-pocket price of $26,500 a year or if they are enrolled in a clinical trial that continues to monitor the drug’s safety and effectiveness. ## One big loophole remains Even if the drug becomes fully approved, CMS said in a [statement](https://www.cms.gov/newsroom/press-releases/cms-announces-plan-ensure-availability-new-alzheimers-drugs) on June 1 that it would cover the drug for patients who agreed to enroll in a national registry that collects “evidence about how these drugs work in the real world.” The requirement is the same that CMS used for the first FDA-approved Alzheimer’s treatment, aducanumab, which was approved despite studies showing differing levels of effectiveness at slowing cognitive decline. Because aducanumab and lecanemab belong to the same class of drugs that target amyloid protein, the agency says the need for additional monitoring is justified. Such a registry does not yet exist, and it’s still unclear how patients will be able to join it. Advocacy groups like the Alzheimer’s Association have questioned the need for the additional step, saying that it will make it harder to access to the treatment. “We continue to believe that registry as a condition of coverage is an unnecessary barrier,” the group said in a [statement](https://www.alz.org/news/2023/cms-requires-registry-fda-alzheimers-treatments) in response to CMS’s decision. --- ### More from TIME --- Not even the makers of the drug understand the move. “The question becomes what CMS means by ‘registry’ or ‘registries,’” says Ivan Cheung, CEO of Eisai Inc. “No one knows the answer—only CMS does. Until CMS puts out an operational manual about how it’s going to work, we are all guessing.” ## Lecanemab’s safety and efficacy In the meeting, panel experts reviewed data from the completed Phase 3 study of the drug, which confirmed that people with mild cognitive impairment or mild Alzheimer’s dementia who received lecanemab had a 27% slower decline in cognitive abilities compared to those getting placebo. Those receiving the drug also improved their ability to perform daily tasks, such as dressing and feeding themselves, compared to those receiving placebo. Dr. Sarah Cohen, medical director of the Toronto Memory Program and one of the researchers involved in testing the drug, said during the meeting that such improvements in daily living, and any extension of the time that Alzheimer’s patients can live independently, are crucial. “The ability to remain at an earlier stage of disease for a longer period of time is incredibly important,” she told the panel. Overall, the panel agreed that the benefits of the drug, which people receive as an infusion every two weeks, outweighed the risks. Some people on the drug developed infusion site reactions and swelling of the brain, called amyloid-related imaging abnormalities, or ARIA. Lecanemab’s label currently includes a warning about the risks of ARIA—which are greater among people who have the ApoE4 gene and are therefore genetically more at risk for Alzheimer’s disease—and the need for doctors to monitor patients for signs of it through brain MRIs. The panel members also discussed a small number of hospitalizations and deaths among people in the study taking lecanemab who were also taking blood-thinning medications like anticoagulants. While some felt they would not recommend people on these medications take lecanemab, others said more data were needed to understand the magnitude of the risk, and that until such data became available, it was premature to exclude any such populations from taking the drug. The FDA will now take the opinions of the panel into consideration and make a final decision on whether to grant full approval to lecanemab by July 6. ## Transcript [00:00] What we discovered is that aging is very likely, [00:02] a Corruption of the software of the body. [00:05] So that as we get older, the software doesn't function pretty [00:08] well. Things, slow down, break and we get diseases. [00:14] In this new work, we show that we can actually reverse that [00:17] process by tapping into a backup copy. [00:18] Rebooting the software into that old computer opening up the possibility [00:22] that one day we can rejuvenate our whole body. [00:27] Dr. David Sinclair, co-director of the Paul F Glen Center, [00:30] for biology of Aging research at Harvard Medical School describes a [00:34] groundbreaking method that could speed up or reverse, [00:36] the aging of cells in the body at least in my does an old [00:40] theory that mutations Drive aging. [00:42] And it's true that our DNA does get damaged and it does lead [00:45] to changes in our genetic code. [00:47] What we're proposing in this new study is that there's another [00:50] type of information in the cell in our bodies, [00:52] hold the epigenetic information. [00:55] And that's the information that we think is a large driver [00:59] of the aging process Sinclair says that the process of Aging [01:02] work. Similarly, to the way that software programs operate [01:05] off Hardware, sometimes software becomes corrupted, and needs a [01:08] reboot through the process of gene therapy cells in the body, [01:12] can be rebooted to restart the backup copy of epigenetic [01:15] instructions. The epigenome consists of chemical compounds, [01:19] that Mark cells and give them instructions for which gains [01:21] turn on and wish to keep silent. [01:23] This inferior race is corrupted signals that can cause cells [01:26] to Asian. Making them useful yet, but we believe that there's [01:30] a universal process that we've tapped into that works, [01:33] not just in my house, but probably in every human on the planet [01:37] and we all have the same program that allows households [01:40] to you. You rejuvenate it in my so we reverse the age of their [01:43] brains and they get their ability to learn. [01:45] Again, that's what with finding is that there's a universal [01:49] backup copy of useful information and all animals and probably [01:53] in us as well. [01:54] The process is still in its infancy. [01:56] So there's still a lot to be figured out Sinclair says that [01:59] his team is already beyond the next step to lab test. [02:01] The system or non-human primate human neurons skin in fibroblast [02:06] cells. While this method won't stop the body from aging is a whole, [02:09] it could Target specific areas to reverse the effects of disease. [02:13] The first disease that I want to trade is Blindness. [02:15] We are very easily able to reverse blindness in mice, [02:19] and the results from the non-human primate. [02:21] Studies will be out in the next few months. [02:23] So we're very excited about being able to treat diseases. [02:27] But if you allow your imaginations, run wild, [02:30] what it could mean is that we can reverse the age of any cell [02:33] in any tissue in any organ? [02:35] And if that's true, then we should be able to rejuvenate [02:38] large parts of the body. [02:40] That's even whole body Rejuvenation at some point. [02:43] What's exciting about the work is that there are many laps around [02:46] the world working on this new cause of aging, [02:48] and learning every week, how to do, [02:51] resetting the system even better than we are doing now. [02:53] And so, even if my lab is not the one that successful, [02:57] they will be a lab around the world that succeeds in resetting, [03:01] the body and rejuvenating it. [03:03] So I'm really excited that within a lifetime, [03:05] we go to see the possibility that aging and be treated like [03:09] any other medical condition. ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/6286157/alzheimers-drug-lecanemab-leqembi-fda/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/6286157/alzheimers-drug-lecanemab-leqembi-fda/"},"headline":"A New Alzheimer's Drug Is One Step Closer to Full Approval.
