A Renaissance for Microflow Liquid Chromatography-Mass Spectrometry?

ALISON HALLIDAY | January 21, 2019 | 79 views

As precision medicine drives the development of more targeted drugs, demands are increasing for more complex biomarker analyses and so researchers are striving to develop new techniques that are robust, highly sensitive, and use ever-smaller sample volumes. Liquid chromatography coupled with mass spectrometry (LC-MS) is widely used for separating, identifying and quantifying substances in biological samples. The first step involves pumping a sample preparation at high pressure through a chromatography column.

Top 10 biotech IPOs in 2019

Article | July 11, 2022

The big question at the start of 2019 was whether the IPO window would stay open for biotech companies, particularly those seeking to pull off ever-larger IPOs at increasingly earlier stages of development. The short answer is yes—kind of. Here’s the long answer: In the words of Renaissance Capital, the IPO market had “a mostly good year.” The total number of deals fell to 159 from 192 the year before, but technology and healthcare companies were standout performers. The latter—which include biotech, medtech and diagnostics companies—led the pack, making up 43% of all IPOs in 2019. By Renaissance’s count, seven companies went public at valuations exceeding $1 billion, up from five the year before

Closing bacterial genomes from the human gut microbiome using long-read sequencing

Article | July 14, 2022

In our lab, we focus on the impact of the gut microbiome on human health and disease. To evaluate this relationship, it’s important to understand the particular functions that different bacteria have. As bacteria are able to exchange, duplicate, and rearrange their genes in ways that directly affect their phenotypes, complete bacterial genomes assembled directly from human samples are essential to understand the strain variation and potential functions of the bacteria we host. Advances in the microbiome space have allowed for the de novo assembly of microbial genomes directly from metagenomes via short-read sequencing, assembly of reads into contigs, and binning of contigs into putative genome drafts. This is advantageous because it allows us to discover microbes without culturing them, directly from human samples and without reference databases. In the past year, there have been a number of tour de force efforts to broadly characterize the human gut microbiota through the creation of such metagenome-assembled genomes (MAGs)[1–4]. These works have produced hundreds of thousands of microbial genomes that vastly increase our understanding of the human gut. However, challenges in the assembly of short reads has limited our ability to correctly assemble repeated genomic elements and place them into genomic context. Thus, existing MAGs are often fragmented and do not include mobile genetic elements, 16S rRNA sequences, and other elements that are repeated or have high identity within and across bacterial genomes.

Selexis Cell Line Development Strategies

Article | February 11, 2020

In today’s biotechnology landscape, to be competitive, meet regulations, and achieve market demands, “we must apply Bioprocessing 4.0,” said Igor Fisch, PhD, CEO, Selexis. In fact, in the last decade, “Selexis has evolved from cloning by limiting dilution to automated cell selection to nanofluidic chips and from monoclonality assessment by statistical calculation to proprietary bioinformatic analysis,” he added. Single-use processing systems are an expanding part of the biomanufacturing world; as such, they are a major component of Bioprocessing 4.0. “At Selexis, we use single use throughout our cell line development workflow. Currently, we have incorporated single-use automated bioprocessing systems such as ambr® and the Beacon® optofluidic platform for accelerated cell line development. By using these systems and optimizing our parameters, we were able to achieve high titers in shake flasks. Additionally, the Beacon systems integrate miniaturized cell culture with high-throughput liquid handling automation and cell imaging. This allows us to control, adjust, and monitor programs at the same time,” noted Fisch.

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.
