Sharing Viral Vector Expertise: A Conversation with Yposkesi’s Chief Executive Officer

As a full-service contract development and manufacturing organization (CDMO) specializing in gene therapy development, Yposkesi produces recombinant adenoassociated virus (AAV) and lentivirus (LV) vectors using adherent-based and suspension-adapted cell expression platforms. Alain Lamproye joined the company as chief executive officer (CEO) in January 2017, having served previously as president of the biopharmaceutical business unit of Novasep (2012–2017) and as CEO of Henogen, its subsidiary dedicated to gene therapy. He has held managerial positions in pharmaceutical operations at Merck Serono (including…

Ask the Expert: Accelerating Development and Manufacturing Platforms for Viral Vectors

Bai-wei Gu, Juan Lagos, and Matthew Weaver (heads of cell line development, upstream process development, and downstream process development groups, respectively, at WuXi Advanced Therapies, ATU) joined forces on 29 October 2019 to feature their company’s viral-vector manufacturing capabilities for cell and gene therapies. In addition to adherent platforms for lentivirus (LV) and adenoassociated virus (AAV) vectors, ATU soon will offer suspension-cultured viral vector platforms for them as well as analytical measures that support release testing. Transitioning from adherent to…

Supply and Demand Trends: Mammalian Biomanufacturing Industry Overview

Since the 1986 approval of the first recombinant therapeutic antibody, OKT3, biopharmaceuticals have become a large percentage of overall pharmaceutical company revenue. In 2018, sales of the top five selling recombinant proteins — Humira (adalimumab, AbbVie), Keytruda (pembrolizumab, Merck), Herceptin (trastuzumab, Genentech), Enbrel (etanercept, Amgen), and Avastin (bevacizumab, Genentech), all antibodies — totaled over US$48 billion. The compound annual growth rate (CAGR) for antibodies revenue was about 20% from 2004 to 2014. Those products include naked monoclonal antibodies (MAbs), Fc-fusion…

Ask the Expert: Accelerating Timelines By Integrating Cell-Line Development and Manufacturing

In a 31 October 2019 “Ask the Expert” presentation, Nicole Wakes (group leader of Abzena’s cell-line development team) observed that drug sponsors often outsource their early upstream activities to a few different contract research organizations (CROs). But that strategy can thwart short timelines and introduce regulatory and financial risks. Wakes described Abzena’s upstream approach, illustrating how partnering with a single, multicompetent CRO from cell line construction through manufacture can streamline workflows. Integrating cell line development and manufacturing in this way…

Ask the Expert: Developing Bioprocesses for Clinical Manufacturing Success

Biopharmaceutical companies need to make critical chemistry, manufacturing, and controls (CMC) decisions during clinical development of recombinant protein biologics and advanced therapies. In a 17 December 2019 “Ask the Expert” webinar, Nigel Shipston (director of program design at FUJIFILM Diosynth Biotechnologies, FDB) reviewed key aspects of selecting and working with a contract development and manufacturing organization (CDMO). He also highlighted important factors that should be considered during early stages of process development. Shipston’s Presentation The sheer magnitude of investment required…

Capacity Analysis for Viral Vector Manufacturing: Is There Enough?

Advanced therapy medicinal products (ATMPs) are engineered to replace defective, disease-causing genes to compensate directly for a genetic defect or to encode a therapeutic protein construct (e.g., chimeric antigen receptor, CAR) for disease treatment. In most instances, a viral vector delivers the engineered genetic payload, targeting cells in situ or ex vivo through cellular modification, expansion, and infusion into a patient. Clinical successes of ATMPs bolstered by regulatory approval of products such as Luxturna (voretigene neparvovec-rzyl, Spark Therapeutics), Kymriah (tisagenlecleucel,…

The Road to Commercialization: A Commercial CDMO’s Perspective

Richard Richieri, chief operation officer (COO) of Avid Bioservices, recently presented an Avid case study and strategy to design, prepare, and execute process validation in preparation for successful product approval inspections. The goals of the presentation were to share lessons about some of the strengths learned from Avid’s experience and to offer advice on industry best practices. Finding a CMO that meets your quality expectations and scale is a key driver for your eventual commercial success. Particularly, working with CMO…

Bioprocess Intensification – Fast, Flexible, and Efficient Solutions

Propelled by single-use systems (SUSs), biopharmaceutical companies are approaching the ideal of continuous bioprocessing. In addition to improving process integrity and decreasing production costs, SUSs have enabled exciting ways to configure, operate, and evaluate manufacturing steps. Sensitive process analytical technologies (PATs) and discriminating data analysis platforms are supplementing those developments, helping process engineers and operators to study and modify workflows in unprecedented ways. The goal now is to intensify: to apply increasingly nuanced process knowledge and growing technological capability in…

Streamlining the Path to Clinical Manufacturing

Careful consideration of lot size is crucial for multiyear success of a cell therapy business. RoosterBio’s product design and acceleration business works with the company’s customers to help make plans that are appropriate for their stages of product and clinical development. We use the following major considerations in creating a sound multiyear strategy with intermediate milestones: Understand what the future looks like and work backward Use reasonable to conservative assumptions to estimate a range of needs Invest in the right…

CMC Development Platforms and Outsourcing to Reduce Timelines

Forty Seven is a company developing novel therapies based on anti-CD47 and other immuno-oncologies. CD47 is called the “don’t eat me” signal that cancer cells give out to escape elimination by the body’s immune system. Qinghai Zhao, vice president of technical development and manufacturing, is one of the scientists working on the company’s magrolimab (5F9) monoclonal antibody that is designed to block the binding of the CD47 signal to the cell receptor SIRP-α while boosting the “eat me” signal that…
