It’s reported according to businesswire, AriBio recently announced that it has signed a licensing agreement for the exclusive marketing rights of AR1001, an investigational drug for the treatment of early Alzheimer’s disease, in China at a price of up to US$770 million. Considering the market competition and sales strategy of Alzheimer’s disease drugs in China, the licensee requested that no disclosure be made until the agreed time. The agreement includes an upfront non-refundable payment of 120 billion won (approximately US$90 million), with a total transaction value of up to 5.59 billion yuan (approximately US$770 million), including milestone payments and additional royalties. Upfront payments will begin in mid-2024. AR1001 is a phosphodiesterase type 5 (PDE5) inhibitor in development and an investigational oral drug for the treatment of Alzheimer’s disease. Pre-clinical studies have confirmed that AR1001 can inhibit neuronal apoptosis and restore synaptic plasticity, thus having neuroprotective effects. AR1001 also demonstrated a ...
Alzheimer’s disease (AD) is a neurodegenerative condition that causes the brain to deteriorate over time, marked by the buildup of certain harmful proteins that eventually lead to a decline in brain function and cell death. These changes can happen long before any symptoms show up. Scientists have found certain proteins in the cerebrospinal fluid that are good indicators of AD. One of the most promising markers for early and more precise detection of AD in the blood is phosphorylated tau at position 217 (pTau217). It’s seen as a game-changer for diagnosing AD sooner, categorizing patients for research studies, and improving how patients are cared for and treated. Now, an innovative and novel blood test can be used in the screening, diagnosis, and monitoring of AD based on the circulating level of this promising biomarker pTau217. ALZpath Dx (Carlsbad, CA, USA) has developed a robust and scalable plasma-based ultra-sensitive assay, branded ...
Scientists have made a significant discovery by identifying five distinct biological variants of Alzheimer’s disease, each potentially requiring unique therapeutic approaches. This finding suggests that drugs previously tested for Alzheimer’s might have been wrongly deemed ineffective or only slightly beneficial due to these variants being unaccounted for. At the core of Alzheimer’s disease is the accumulation of amyloid and tau proteins in the brain. However, this aggregation is just one aspect of the disease’s complexity. Researchers, including those from Amsterdam UMC (Amsterdam, Netherlands), have employed innovative methods to analyze additional biological processes involved in Alzheimer’s. These processes, which include inflammation and the growth of nerve cells, were studied through the measurement of various biomarkers in the cerebrospinal fluid of patients exhibiting amyloid and tau accumulations. In their analysis of the cerebrospinal fluid of 419 individuals diagnosed with Alzheimer’s, the researchers assessed 1,058 proteins and identified five distinct biological subtypes within ...
Researchers at the University of Wisconsin–Madison have identified a protein key to the development of a type of brain cell believed to play a role in disorders like Alzheimer’s and Parkinson’s diseases and used the discovery to grow the neurons from stem cells for the first time. The stem-cell-derived norepinephrine neurons of the type found in a part of the human brain called the locus coeruleus may enable research into many psychiatric and neurodegenerative diseases and provide a tool for developing new ways to treat them. Yunlong Tao, an investigator at Nanjing University in China who was a research professor at UW–Madison’s Waisman Center when the study was performed, and Su-Chun Zhang, a UW–Madison professor of neuroscience and neurology, published their work on the cells, which they call LC-NE neurons, today in the journal Nature Biotechnology. Norepinephrine neurons in the locus coeruleus regulate heartbeat, blood pressure, arousal, memory, attention and ...
It is well known that sleep is the best medication. However, it is still unknown why the brain recovers better in sleep and whether these processes can be controlled. Recent discoveries have shown that the lymphatic system of the brain is activated during sleep, which contributes to the removal of metabolites, toxins and unnecessary molecules from its tissues. Sleep disturbance contributes to the deposition of metabolites in the central nervous system (CNS). For example, sleep is a biomarker for the development of Alzheimer’s disease. This is due to the fact that the toxic metabolite beta-amyloid is excreted from brain tissue during sleep. Sleep deprivation leads to the accumulation of toxin in the CNS, which over time can lead to the development of Alzheimer’s disease. In this pilot study, the researchers have shown that non-invasive sleep photobiomodulation technology can effectively increase lymphatic excretion of beta-amyloid from the brain tissues of mice ...
The secret to protecting your memory may be a staple of a bodybuilder’s diet. RUSH researchers recently discovered that a muscle-building supplement called beta-hydroxy beta-methylbutyrate, also called HMB, may help protect memory, reduce plaques and ultimately help prevent the progression of Alzheimer’s disease. HMB is not a prescription drug or a steroid, but an over-the-counter supplement that is available in sports and fitness stores. Bodybuilders regularly use HMB to increase exercise-induced gains in muscle size and strength while improving exercise performance. HMB is considered safe even after long-term use, with no known side effects. “This may be one of the safest and the easiest approaches to halt disease progression and protect memory in Alzheimer’s disease patients,” said Kalipada Pahan, PhD, the Floyd A. Davis, MD, Professor of Neurology and professor of neurological sciences, biochemistry and pharmacology at RUSH Medical College. Studies in mice with Alzheimer’s disease ...

After a full FDA approval last week triggered Medicare coverage of Eisai and Biogen’s Leqembi, doctors are still trying to work out the logistics of testing and reimbursement. But at least two experts remain positive about the drug’s efficacy and safety profile.The new Leqembi label carries a boxed warning about the risks of brain bleeding and swelling known as amyloid-related imaging abnormalities (ARIA). But two Alzheimer’s opinion leaders suggested the side effect is manageable typically by extensive monitoring in the first six months, Leerink Partners analysts said in a Wednesday note. But the two experts were split on whether they intend to treat patients with the ApoE ε4 genetic trait. The FDA label requires testing for that biomarker before initiating Leqembi to inform the risk of ARIA. While one expert felt comfortable giving Leqembi to APOE4 carriers as long as the patients are informed of the risk, the other ...
Starting this July, people diagnosed with Alzheimer’s before age 65 will have a new opportunity to connect with others while exploring the great outdoors through a program called SOAR. The name is an acronym for Shared Outdoor Adventures for Resilience. Offered by the UW Medicine Memory and Brain Wellness Center, SOAR will feature free monthly hikes in the Puget Sound area for small groups of people with younger-onset Alzheimer’s. Each participant brings along a family member or friend. A lifelong recreation specialist from Seattle Parks and Recreation will lead the hikes. Optional transportation is provided. Hikes will be up to 3 or 4 miles. The type of terrain will vary among the different hikes to provide a challenge but still be accessible to a wide range of participants. Volunteer naturalists will join periodically to talk about plants and animals in the region. SOAR will conclude with a nature retreat at ...
It’s official: Roughly half a year after the FDA granted an accelerated nod to Eisai and Biogen’s new Alzheimer’s disease med lecanemab, the companies have converted that green light into a full-fledged, traditional approval. Now, the drug—also known as Leqembi—is set to unshackle itself from a strict coverage determination by the Centers for Medicare & Medicaid services (CMS). With a full approval in hand, Leqembi has become the first treatment shown to reduce the rate of disease progression and slow cognitive and functional decline in adults with Alzheimer’s under the traditional approval pathway, Eisai Executive Vice President Alex Scott, who oversees government affairs, said in an interview. Those benefits stand across a “broad patient group that’s generalizable to the whole Medicare population,” he added. Leqembi won an accelerated FDA approval in January based on its ability to reduce amyloid beta plaque, a marker of Alzheimer’s disease that’s believed to be ...
