Upstream Single-Use Technologies

Optimizing for the Future

The 2013 biennial meeting of the European Society for Animal Cell Technology (ESACT) was in Lille, France this past June. While there, BPI editorial advisor Miriam Monge (vice president of Biopharm Services Ltd.) interviewed ESACT executive committee member Hitto Kaufmann, PhD (vice president of biopharmaceutical process sciences for Boehringer Ingelheim). They talked about some scientific developments being discussed at this year’s ESACT conference as well as Boehringer Ingelheim’s recent announcement about setting up in China and Kaufmann’s own thoughts on…

Cost-Effectiveness and Robustness Evaluation for Biomanufacturing

As the biotech sector has matured, it has come under increasing economic and regulatory pressures for continuous improvement in both drug development and manufacturing. As a result, assessing the value potential of alternative strategies has become critical to decision-making in areas such as bioprocess and facility design, capacity sourcing, and portfolio selection. Related decisions typically involve large cash expenditures and thus have a direct bearing on the feasibility of business units and whole companies. Figure 1:  () Making such decisions…

Inactivated Poliovirus Vaccine Made in Modular Facilities with Single-Use Technology

If current efforts to eradicate polioviruses worldwide are successful, then the oral poliovirus vaccine (OPV) currently used for routine immunization in low- and middle-income countries (LMICs) will be replaced by inactivated poliovirus vaccine (IPV). IPV will become the only option for such countries if they want to continue to vaccinate against polio (1). Because IPV is currently considered to be too expensive for use in LMICs, strategies are being undertaken to make IPV more affordable (2). Some experts estimate that…

Development of Protein Capsular Matrix Vaccine Platform Technology

Polysaccharide vaccines account for about 30% of the total >$20-billion/year vaccine market. Despite efficacious vaccines in the field, diseases such as invasive Streptococcus pneumoniae and typhoid fever persist. Development of multivalent polysaccharide conjugate vaccines requires complex chemistries and multiple, expensive good manufacturing practice (GMP) process steps. Matrivax Research and Development Corporation is developing a protein capsular matrix vaccine (PCMV) technology that simplifies synthesis of polysaccharide vaccines with fewer process steps than are required by typical conjugation vaccine processes. Polysaccharide Vaccine…

Standards for Ancillary Materials Used in Cell- and Tissue-Based Therapies

Cell- and tissue-based therapies are being used increasingly to treat many diseases for which currently no other adequate treatment options are available. These products contain human or animal cells that can replace, regenerate, or augment a recipient’s diseased, dysfunctional, or injured cells, tissues, or organs. Cells or tissues might be unmanipulated, or their biological characteristics can be altered ex vivo before administration of the final product to patients. Examples of cell therapies range from traditional blood transfusions to recent approaches…

Drug Products for Biological Medicines

The California Separation Science Society (CASSS) held a Chemistry, Manufacturing, and Controls (CMC) Strategy Forum on drug products for biological medicines in July 2012 in Bethesda, MD. Topics included novel delivery devices, challenging formulations, and combination products. This CMC Strategy Forum aimed to promote an understanding of how best to increase the speed and effectiveness of drug product and device development for both large and small companies. Participants focused on areas that improve the likelihood for regulatory success, reduce risk,…

Concerns, Collaboration, and Capacity

The BPI Theater is a 50-seat venue that for seven years has been located at the heart of the BioProcess Zone on the exhibition floor of the BIO International Convention. There, BPI provides attendees with four days of live presentations focusing on the latest scientific advances and business trends in biotherapeutic development and manufacturing. On Monday afternoon, 22 April 2013, Patricia Seymour of BioProcess Technology Consultants (BPTC) moderated a roundtable discussion on biosimilar development in the BPI Theater at BIO…

Better Cells for Better Health

Since its inception 35 years ago, the biennial meeting of the European Society for Animal Cell Technology (ESACT) has built on a tradition of combining basic science and applications into industrial biotechnology to become the international reference event in its subject matter. Every other year, this gathering of academics and industry professionals features a famously exciting social program and an extensive vendor/supplier exhibition specific to animal cell technology. ESACT meetings are much-anticipated international venues for information exchange, inspiration, networking, and…

Development and Qualification of a Scalable, Disposable Bioreactor for GMP-Compliant Cell Culture

During the past decade, single-use bioreactors have become widely accepted for use in cell culture process development and clinical manufacturing. Their key benefits over stainless steel bioreactors are flexibility, cost, and time savings associated with the reduction of cross-contamination risks (1). Here, we describe our approach to development and qualification of the Biostat STR single-use, stirred-tank bioreactor. Unlike other stirred single-use bioreactors, it offers a similar design to that of well-established, conventional (stainless steel) stirred-tank bioreactors. Disposability of the single-use…

Drug Products for Biological Medicines

Traditionally, the CaSSS CMC Strategy Forum meetings have provided a scientific focus on the development of biotech drug substances and their manufacture and characterization, leaving the development of drug product formulation and filling, understanding primary containers, and considering novel delivery systems somewhat out of scope. Over recent years, however, the importance of investing more science and technology into drug product development has become evident as different product types, higher protein concentrations, and doses and requirements for improved delivery of biological…
