New digital filter approach aims to improve chemical measurements

eurekalert | May 02, 2019

Precise measurements are critical to the discovery, development and usage of medications. Major financial and scientific decisions within pharmaceutical companies are informed by the outcomes of chemical and biological analyses. Even slight measurement variations can add risk and uncertainty in these high-stakes decisions. A Purdue University professor and expert in measurement science has led a team to design a new filter aimed at helping drug developers and researchers create more exact measurements early in the drug development stage, which can ultimately help move a drug to clinical trials faster. Garth Simpson, a professor of analytical and physical chemistry in Purdue's College of Science, created the filter as part of his work with the Merck-Purdue Center for Measurement Science. The academic-industrial partnership, which started in 2017, is focused on developing technology to improve drug manufacturing and formulation to support the pharma industry in expediting drug discovery and delivery. According to the Food and Drug Administration, it can take up 10 to 15 years or longer to move a drug from discovery to the public.

Vaxxinity Announces First Subjects Dosed in Phase 1 Clinical Trial of VXX-401, Investigational Anti-PCSK9 Vaccine to Treat Hypercholesterolemia

Vaxxinity, Inc. | March 21, 2023

Vaxxinity, Inc. a U.S. company pioneering the development of a new class of immunotherapeutic vaccines, announced that the first subjects have been dosed in a randomized, double-blind, placebo-controlled Phase 1 clinical trial of VXX-401, an investigational vaccine designed to lower low-density lipoprotein (LDL) cholesterol, a known factor contributing to heart disease, by targeting proprotein convertase subtilisin/kexin type 9 serine protease (PCSK9). Heart disease remains the leading cause of death globally, claiming over 18 million lives per year, despite the existence of approved treatments that lower LDL. “This is an exciting milestone for VXX-401 and Vaxxinity in our pursuit to vaccinate the world against heart disease with a preventative option that is convenient and accessible, addressing an unmet need to combat the leading global cause of death,” said Mei Mei Hu, Chief Executive Officer of Vaxxinity. “PCSK9 antibody therapies are well-tolerated and effective, but huge unmet patient need remains. In order to solve the problem of heart disease, the world needs a scalable, accessible technology that can reach the hundreds of millions, if not billions of people at risk. With an LDL-lowering vaccine we can potentially offer an option that’s cost-effective, safe, convenient, long-acting, and deployable.” The multicenter Phase 1 dose-escalation trial aims to enroll 48 subjects aged 18 to 75 years, with LDL cholesterol between 2.59 and 4.89 mmol/L. The objectives of the trial are to evaluate safety, tolerability and immunogenicity (as measured by serum anti-PCSK9 antibody titers). Pharmacodynamics of the immune response will be measured by LDL cholesterol levels, an established model of PCSK9 inhibition in hypercholesterolemia. “We’re excited to get this first-in-human trial of VXX-401 started. The concept of a vaccine for cholesterol could be a game-changer in cardiovascular health due to its potentially very broad reach and impact on human health,” said Professor Stephen Nicholls of Monash University and Victorian Heart Hospital in Australia. “Targeting PCSK9 with a monoclonal antibody is a proven and effective approach for lowering cholesterol and reducing the risk of heart attack and stroke. Despite the availability of statins and the approval of PCSK9-targeting medicines, there is still a need for new therapies. VXX-401 has the potential to extend the use of PCSK9 inhibition to the full population who could benefit.” Earlier this month, Vaxxinity presented pre-clinical data at the American College of Cardiology/World Congress of Cardiology Annual Scientific Session demonstrating that VXX-401 induced robust anti-PCSK9 antibodies and durable LDL cholesterol lowering without affecting high-density lipoprotein (HDL) cholesterol levels, indicating that VXX-401 has the potential to be a safe and effective LDL lowering therapy. Data in non-human primate studies show that VXX-401 was well tolerated and provided durable and significant LDL reduction of 30% to 50% change from baseline. The data also demonstrate VXX-401’s immunogenicity: purified antibodies from immunized animals bound to human PCSK9 with high affinity, and exhibited a dose-dependent functional inhibition of PCSK9 in vitro. Additionally, Peripheral Blood Mononuclear Cells (PBMCs) collected prior to immunization did not release cytokines upon stimulation with various components of the vaccine, suggesting that VXX-401 may safely overcome immune tolerance. About VXX-401 VXX-401 was designed using Vaxxinity’s proprietary synthetic peptide vaccine platform and is being developed for the treatment of hypercholesterolemia. The platform is designed to harness the immune system to convert the body into its own natural “drug factory,” stimulating the production of antibodies. VXX-401 is designed to induce robust, long-acting antibodies against PCSK9 in order to lower LDL cholesterol. About Vaxxinity Vaxxinity, Inc. is a purpose-driven biotechnology company committed to democratizing healthcare across the globe. The company is pioneering a new class of synthetic, peptide-based immunotherapeutic vaccines aimed at disrupting the existing treatment paradigm for chronic disease, increasingly dominated by monoclonal antibodies, which suffer from prohibitive costs and cumbersome administration. The company’s proprietary technology platform has enabled the innovation of novel pipeline candidates designed to bring the efficiency of vaccines to the treatment of chronic diseases, including Alzheimer’s, Parkinson’s, migraine, and hypercholesterolemia. The technology is also implemented as part of a COVID-19 vaccine program. Vaxxinity has optimized its pipeline to achieve a potentially historic, global impact on human health.
