Better Purification and Recovery in Bioprocessing

August 2, 2021 | 566 views

In the downstream portion of any bioprocess, one must pick through the dross before one can seize the gold the biotherapeutic that the bioprocess was always meant to generate. Unfortunately, the dross is both voluminous and various. And the biotherapeutic gold, unlike real gold, is corruptible. That is, it can suffer structural damage and activity loss. When discarding the dross and collecting the gold, bioprocessors must be efficient and gentle. They must, to the extent possible, eliminate contaminants and organic debris while ensuring that biotherapeutics avoid aggregation-inducing stresses and retain their integrity during purification and recovery. Anything less compromises purity and reduces yield.

To purify and recover biotherapeutics efficiently and gently, bioprocessors must avail themselves of the most appropriate tools and techniques. Here, we talk with several experts about which tools and techniques can help bioprocessors overcome persistent challenges. Some of these experts also touch on new approaches that can help bioprocessors address emerging challenges.

Top 10 biotech IPOs in 2019

Article | June 22, 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

Cell Out? Lysate-Based Expression an Option for Personalized Meds

Article | July 14, 2022

Cell-free expression (CFE) is the practice of making a protein without using a living cell. In contrast with cell line-based methods, production is achieved using a fluid containing biological components extracted from a cell, i.e., a lysate. CFE offers potential advantages for biopharma according to Philip Probert, PhD, a senior scientist at the Centre for Process Innovation in the U.K.

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

Article | August 16, 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.

Omega Therapeutics Announces Clinical Supply Agreement to Evaluate the Combination of OTX-2002 and Atezolizumab in Hepatocellular Carcinoma

Globenewswire | March 31, 2023

Omega Therapeutics, Inc. a clinical-stage biotechnology company pioneering the development of a new class of programmable epigenetic mRNA medicines, today announced a clinical supply agreement with Roche to evaluate OTX-2002, its lead candidate in development for the treatment of MYC-driven hepatocellular carcinoma (HCC), in combination with Roche’s anti-PD-L1 therapy, atezolizumab, as part of Omega’s Phase 1/2 MYCHELANGELO™ I clinical trial. “This agreement with Roche represents continued execution of our clinical trial strategy and the next step toward realizing the transformative potential of OTX-2002, a first-in-class epigenomic controller designed to pre-transcriptionally downregulate the MYC oncogene, a historically undruggable target,” said Mahesh Karande, President and Chief Executive Officer of Omega Therapeutics. “In preclinical studies, OTX-2002 demonstrated synergistic antitumor activity with existing standard of care therapies for HCC, including anti-PD-1 and anti-PD-L1 immune checkpoint inhibitors, with minimal impact on safety and tolerability. Through the combination of two orthogonal treatments, OTX-2002 and atezolizumab, a leading anti-PD-L1 therapy, we aim to simultaneously disrupt multiple drivers of cancer progression with the goal of improving treatment outcomes. With Roche’s support and partnership, we look forward to assessing the ability of this novel combination approach to enhance antitumor immune response in patients with advanced HCC.” The ongoing Phase 1/2 MYCHELANGELO I trial is designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary antitumor activity of OTX-2002 as a monotherapy (Part 1) and in combination with standard of care therapies in patients with relapsed or refractory HCC and other solid tumor types known for association with the MYC oncogene. Preliminary data from the Phase 1 monotherapy dose escalation portion of the study are anticipated in 2023. Under the terms of this agreement, Roche will supply atezolizumab and Omega will evaluate the combination as part of the overall conduct of the trial.
