Messenger RNA Drugs: Engaging the Machinery of Patients’ Cells to Therapeutic Effect

Although most of the bioprocess industry has focused on process development for large-molecule formulations (e.g., protein drugs), a growing segment of the industry has been concentrated on other types of biotherapeutics to leverage advances in understanding of immunology and genetic engineering. Such technologies may emerge both as tools for drug manufacturing and at some point, as biopharmaceuticals, biotherapeutics, vaccines, and cell and gene therapies,  themselves. What brings mRNA research to BioProcess International’s attention is the increasing interest turned toward therapeutic…

Development and Biomanufacturing Strategies for Next-Generation Antibody-Drug Conjugates

The development and manufacture of antibody-drug conjugates (ADCs) requires a series of complex steps. ADC manufacturers must comply with guidelines for both the small-molecule linker-drug and the monoclonal antibody (MAb). The authors describe their company’s development of its lead ADC product. They review process decisions, including the issues that factored into their selection of single-use systems, manufacturing challenges (differences between ADCs and MAbs), and testing methodologies for extractables and leachables. Synthon began as a small-molecule generics company in 1991. During…

Introduction: The Ins and Outs of Market Demand

From transport and holding of bulk drug substance to shipping, warehousing, tracking, and distribution of final packaged drug products, biopharmaceutical supply chain logistics can be described as an industry in itself. And that’s just one side of the story. Even though much of the work of establishing and maintaining supply chains might happen outside the manufacturing environment, all organizations that develop processes and final products depend on having the raw materials and available components and resources to do their work.…

Standardizing Human MSCs As Critical Raw Materials in Cell Therapy Products: Streamlining Clinical Translation

Advancements in cell therapy, biofabrication, and synthetic biology have driven the growth of the global regenerative medicine (RegenMed) industry in the past decade. The industry has developed innovative treatment options for patients with otherwise unmet medical needs (1). Human or animal cells or tissues are used as critical raw materials in cell therapy products that can replace, regenerate, or augment patients’ diseased, dysfunctional, or injured cells, tissues, or organs. These cells or tissues can be unmanipulated, or their biological characteristics…

Spray Freeze-Drying Technology: Enabling Flexibility of Supply Chain and Drug-Product Presentation for Biologics

Biopharmaceutical drug substances (DSs) and drug products (DPs) commonly are stored frozen or refrigerated to maintain stability through long-term storage, handling, and transportation (1). Temperature excursions during storage and transport can affect product quality adversely by compromising the safety and efficacy of these molecules. Thus, cold-chain management throughout the shelf life of these products is a critical component in the supply chain strategy for them. The cost and complexity of cold-chain management is a well-known challenge faced by the biopharmaceutical…

A Multistep Research Protocol to Develop and Implement Validated Guidelines for CMO RFI and RFP Processes: Biopharmaceutical Vendor Evaluation and Selection Minimum Standards (BioVesel)

Pursuant to the proposal for validated minimum standards for biopharmaceutical contract manufacturing organization (CMO) request-for-information (RFI) and request-for-proposal (RFP) processes (biopharmaceutical vendor evaluation and selection minimum standards, BioVesel) (1), we propose herein a multistep research protocol to develop and implement the BioVesel standards. This proposal is intended as a basis for discussion among mulitple stakeholders. Detailed research protocols for each proposed stage in the development and implementation of BioVesel will be drafted and published separately. The context of the proposed…

Development of a Standardized Extractables Approach for Single-Use Components: General Considerations and Practical Aspects — A Manufacturer’s Perspective

The subject of extractables for single-use bioprocess contact materials has been a subject of heated debate since roughly the summer of 2012, when the first ISPE paper was published issuing a call to action to develop a standardized extractables protocol for the industry (1). As a supplier that pioneered the science of extractables (2‒11) and has published extractables data for our products for over 20 years, Sartorius Stedim Biotech (SSB) took the opportunity to look back, take stock, rationalize, and…

Bridging Polymer Science to Biotechnology Applications: A Single-Use Technology Conference Report

Single-use (SU) technology is used more every year throughout the biotechnology industry. As applications now span from cell banking to drug product, that in turn is raising interest in the interaction of extractables with proteins and cells. The second “Single-Use Technologies” conference organized through Engineering Conference International (ECI) was subtitled “Bridging Polymer Science to Biotechnology Applications” and delved into the science of plastics in bioprocessing applications. On 7–10 May 2017 at the Hotel dos Templários in Tomar, Portugal, people from…

Using Data and Advanced Analytics to Improve Chromatography and Batch Comparisons

With all the hype surrounding the industrial Internet of Things (IoT), cloud computing, and digital transformations, the most important information technology factors still are data and the connections of sensors, systems, and applications that generate, store, find, and use those data to obtain operational intelligence. Data volumes are increasing rapidly, and they will continue to do so. The ability to find and make sense of data to obtain intelligence that improves process outcomes is more important than ever. For clinical-…

Rational Selection of Sugars for Biotherapeutic Stabilization: A Practitioner’s Perspective

Biotherapeutics from recombinant DNA technology include diverse modalities such as peptides; enzymes, antibodies, and other proteins; nucleic acids; and cellular therapies. Such products present physical, chemical, and biophysical challenges. Excipients used in stabilization of these biotherapeutics can be broadly classified into the following classes (subgroups) that have been reviewed carefully elsewhere (1–4) : Buffers (e.g., phosphate, acetate, and histidine) Tonicity agents/stabilizers (sugars such as sucrose, polyols such as sorbitol) Bulking agents (lyoprotectants such as mannitol) Surfactants (e.g., polysorbates) Antioxidants (e.g.,…
