Better Purification and Recovery in Bioprocessing

August 2, 2021 | 876 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.

Nurix Announces Strategic Collaboration with Seagen Combining Industry Leading Technologies of Targeted Protein Degradation and Antibody-Drug

globenewswire | September 12, 2023

Nurix Therapeutics, Inc. a clinical stage biopharmaceutical company developing targeted protein modulation drugs designed to treat patients with hematologic malignancies and solid tumors, today announced that it has entered into a multi-year, multi-target strategic collaboration agreement with Seagen Inc. to advance a new class of medicines called Degrader-Antibody Conjugates (DACs) for use in cancer. The collaboration between the two companies will focus on an innovative approach to combine two powerful technologies to target cancer—antibody-drug conjugation (ADC) and targeted protein degradation (TPD)—with the goal of creating drugs with new mechanisms of action as well as improved specificity and anti-cancer activity. “By combining the tissue and tumor specificity of antibodies with highly potent and catalytic targeted degradation of cancer driver proteins, we believe that DACs may represent a next generation of cancer medicine for a wide range of solid tumors and hematologic malignancies,” said Arthur T. Sands, M.D., Ph.D., president and chief executive officer of Nurix. “With Seagen, our strategic goal is to advance ADC technology to the next level to provide patients with new DAC drugs that deliver greater anti-tumor efficacy and safety compared to currently available agents.” “The targeted protein degrader modality provides unique advantages over payloads currently employed across the ADC field,” said Gwenn M. Hansen, Ph.D., chief scientific officer of Nurix. “This collaboration is a new application of our DELigase technology, and we are delighted to work with Seagen, a pioneer in the development and commercialization of ADC therapeutics, to create a new generation of drugs to fight cancer.” Under the terms of the agreement, Nurix will receive an upfront payment of $60 million and has the potential to receive up to approximately $3.4 billion in research, development, regulatory and commercial milestone payments across multiple programs. In addition, Nurix will be eligible for mid-single to low double digit tiered royalties on future sales, and Nurix retains an option for U.S. profit sharing and co-promotion on two products arising from the collaboration. As part of the multi-year collaboration, Nurix will use its proprietary DELigase platform to develop a suite of targeted protein degraders against multiple targets nominated by Seagen that are suitable for antibody conjugation. Seagen will be responsible for conjugating these degraders to antibodies to make DACs and advancing these DAC drug candidates through preclinical and clinical development and commercialization. Given the potential to conjugate multiple antibodies to unique degraders, several DAC drugs may be developed and commercialized within this collaboration. With the receipt of the $60 million upfront payment, Nurix expects that its existing cash, cash equivalents and marketable securities, excluding any future potential milestones from collaborations, will be sufficient to fund its operating activities into the second quarter of 2025. About Nurix Therapeutics, Inc.
