Participants will be treated with ANVS401 for four weeks. This result demonstrates the ability of ANVS401 to reach the nervous system, and its mechanism of action, the translational inhibition of α-synuclein expression, supporting further development of ANVS401 as a drug for the treatment of PD. Both compounds were originally developed by Torrey Pines Therapeutics and licensed to QR Pharma in 2008.  Linked In  Twitter ANVS401, also known as Posiphen, is an oral small molecule that prevents the production of these protein aggregates by interfering with their translation — the process through which a protein is made from a messenger RNA template by ribosomes, the cell’s protein-making machinery. We have an ongoing Phase 2a study in AD patients and plan to commence a second Phase 2a study in PD patients. An estimated 5.8 million people in the U.S. have AD and there are approximately 44 million people worldwide living with the disease. ANVS401 has a unique mechanism of action in that it inhibited the translation and, therefore, the levels of several key neurotoxic proteins both in vitro and in vivo including APP, tau and αSYN. She specializes in cancer biology, immunology, and genetics. ANVS401 attacks multiple neurotoxic proteins that result from acute and chronic injury to the brain. “We are excited to receive IRB approval to move forward with this Phase 2 study in PD [Parkinson’s disease] and AD [Alzheimer’s disease],” Maria Maccecchini, PhD, the CEO of Annovis Bio, said in a press release. Primary endpoints are safety, pharmacokinetics in plasma and CSF, and the rate of turnover of CSF Aβ40 using the stable isotope labeling kinetics (SILK) technique (see Paterson et al., 2019). by Marisa began working with BioNews in 2018, and has written about science and health for SelfHacked and the Genetics Society of America. Dave@redchip.com, © 1985 - 2021 BioSpace.com. In doing so, it is expected that ANVS401 will lower the levels of toxic proteins and improve transport within neurons (axonal transport). Marisa holds an MS in Cellular and Molecular Pathology from the University of Pittsburgh, where she studied novel genetic drivers of ovarian cancer.

Berwyn, PA - September 3, 2021 (GLOBE NEWSWIRE) - Annovis Bio, Inc. (NYSE: ANVS), a clinical-stage, drug platform company addressing neurodegeneration, such as Alzheimer's disease (AD), Parkinson's disease (PD) and Alzheimer's in Down Syndrome (AD-DS), today announced that an interview with CEO and President Dr. Maria Maccecchini, Ph.D. will air on The RedChip Money . In August 2020, Annovis began a Phase 1/2 dose-finding biomarker study in early AD and Parkinson’s disease patients. The study is recruiting 24 participants with a diagnosis of amnestic MCI or probable mild AD, and CSF levels of Aβ42 consistent with AD. Ten days of treatment in people with MCI led to reductions in CSF of APP cleavage fragments sAPPα and β, and Aβ42, total tau, and phosphorylated tau, and the inflammation markers YKL-40, complement C3, and MCP-1.

The upcoming clinical trial plans to enroll a total of 68 people with Alzheimer’s or Parkinson’s at 15 sites across the U.S. Posiphen, also known as ANVS-401, is the pure (+) enantiomer of phenserine. In the study, ANVS401 treatment normalized impairments in spatial working memory, contextual fear learning, and synaptic function in APP/presenilin-1 mice, without affecting their visual activity, motor skills, or motivation and without affecting wild-type mice. Posiphen acts on iron-response element sequences in the 5' untranslated region of APP mRNA to inhibit protein synthesis. When this information flow is impaired, the nerve cell gets sick and dies. Gastrointestinal dysfunction is a particularly common non-motor abnormality in PD, documented in over 80% of patients. Target Type: Amyloid-Related (timeline), alpha-synuclein “No drug to date has shown efficacy in two totally different animal models of neurodegeneration,” commented Maria Maccecchini, Ph.D., CEO of Annovis Bio. Posiphen reportedly also blocks translation of α-synuclein mRNA, implying potential application in Parkinson’s disease (Rogers et al., 2011; Mikkilineni et al., 2012; Yu et al., 2013). Trial researchers will evaluate the steps in the toxic cascade that lead to neuron death in both conditions, and assess how ANVS401 affects this cascade. Headquartered in Berwyn, Pennsylvania, Annovis Bio, Inc. (Annovis) is a clinical-stage, drug platform company addressing neurodegeneration, such as Alzheimer’s disease (AD), Parkinson’s disease (PD) and Alzheimer’s in Down Syndrome (AD-DS). Never disregard professional medical advice or delay in seeking it because of something you have read on this website. Adverse effects did not increase significantly at doses of up to 60 mg four times a day for 10 days, at which point Posiphen reached brain concentrations presumed sufficient to inhibit APP production. Translational inhibition of APP by ANVS401 has been shown to reduce APP and its fragments in cell culture, animal models, and mildly cognitively impaired patients, making it a promising drug candidate for the treatment of AD. Importantly, the data are consistent with prior clinical and preclinical results, the drug's mechanism of action and over 10 years of basic research. Facebook Part 1 finished in early 2021, and Annovis presented results at the 2021 AAIC on July 28. Most common side effects were dizziness, nausea, and vomiting that increased with dose. Other endpoints include pharmacokinetic, functional, and cognitive endpoints. This Phase 2 study will also assess the safety and tolerability of the investigational medication, as well as its effect on symptoms — including motor impairment and non-motor symptoms in Parkinson’s patients, and memory and cognitive problems in those with Alzheimer’s, the release stated.

Phenserine also inhibits acetylcholinesterase, while Posiphen does not. The study used a mouse model of AD to examine ANVS401’s efficacy, pharmacodynamics, and pharmacokinetics. Further, certain forward-looking statements are based on assumptions as to future events that may not prove to be accurate. Fri, 03 Sep 2021. The Parkinson’s study, conducted by Professor Robert Nussbaum at University of California San Francisco and published in the American Journal of Neurodegenerative Disease, is the first study showing the preclinical efficacy of ANVS401 in improving the colonic motility in mouse models of gastrointestinal dysfunction in early PD. They are randomized to receive 60, 120, or 180 mg daily, divided into three doses, or placebo for 23 to 25 days. Synonyms: ANVS-401, (+)-phenserine, Posiphen tartrate ANVS401 had a prolonged effect in reducing APP and all related peptides for at least nine hours after the last dose.

We expect our treatment to improve memory loss and dementia associated with AD and AD-DS, as well as body and brain function in PD. The primary outcome is adverse events. There were no serious adverse events. The AD patients had a decrease in all amyloid/tau biomarkers, with a 12 percent reduction in pTau, and improvement in the Aβ42/40 ratio. This second volume follows on from Part I by reviewing the variety of animal models of PD current available (from drosophila to rodents to non-human primate species) and their specific contributions to PD research. Pharmacokinetics studies revealed that ANVS401 is more abundant in the brain than in blood, in agreement with its lipophilicity, and the main metabolite is N8-NorPosiphen, a molecule with similar properties as ANVS401. In Part 1, 14 AD and 14 PD patients were to be randomized roughly 2:1 to 80 mg Posiphen or placebo, taken daily for 23 to 27 days. Decoding Darkness takes us deep into the minds and far-flung labs of many a prominent researcher, offering an intimate view of the high stakes of molecular genetics, the revolution that propels it, the obstacles that threaten to derail it, ... "A fascinating look at the gendering of smart homes, how they came to be so, and how modern households can and should be domains of equality"-- It reduced APP and Aβ in neuronal cultures and brains of wild-type and AD transgenic mice (Lahiri et al., 2007; Marutle et al., 2007). It is dosed by mouth and enters the brain. Both Parkinson’s and Alzheimer’s are characterized by the pathological buildup of clumps of proteins in the brain — specifically, clumps of the protein alpha-synuclein in Parkinson’s, and of beta-amyloid and tau in Alzheimer’s. Both Posiphen and phenserine reduce production of amyloid precursor protein by blocking translation of its mRNA. In our PD animal studies, ANVS401 lowered levels of α-synuclein and normalized gut motility in two transgenic animal models of PD. The drug was reported to improve outcomes in rodent stroke models (Yu et al., 2020; Turcato et al., 2018).

In other words, the study will determine whether ANVS401 can lessen the accumulation of toxic proteins, and whether the reduction achieved leads to improvements in neuronal health and brain function. Suite 700 Always seek the advice of your physician or other qualified health provider with any questions you may have regarding a medical condition. The company reported significant reductions by 43 and 28 percent in inflammatory markers sTREM2 and GFAP in treated PD patients; a 55 percent YKL40 reduction did not meet statistical significance. Its concentration was higher in the brain than in plasma, and the most abundant metabolite was N8-NorPosiphen. -phenserine is a R-enantiomer (positive isomer) of phenserine, being developed by Annovis Bio (formerly QR Pharma), under a licence from Horizon Therapeutics The Alzheimer’s study, conducted by Professor Ottavio Arancio at Columbia University and published in Alzheimer’s & Dementia: Translational Research & Clinical Interventions, is the first study demonstrating the therapeutic efficacy in animals of inhibiting the translation of APP and its fragments in an AD model. PD affects an estimated one million people in the U.S. and as many as 10 million globally. Company: Annovis Bio. The trial was paused from March to October 2020 due to COVID19, and is expected to finish in December 2021. It was also tested in the APP-overexpressing Ts65DN mouse model of Down's syndrome, where 50 mg/kg for 26 days lowered expression of APP and its C-terminal fragments, corrected deficits in axonal transport, and normalized neurotrophin signaling (Chen et al., 2021). These  accumulations disrupt communication between nerve cells and eventually leads to cell death. Posiphen, also known as ANVS-401, is the pure (+) enantiomer of phenserine. Dave Gentry, CEO Results of three Phase 1 studies of Posiphen are published (Maccecchini et al., 2012). The Alzheimer Disease Cooperative Study group is running the trial at six academic medical centers in the U.S. As of February 2020, 11 participants had enrolled, and no adverse effects were reported (company press release).
