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.

A biopharmaceutical company’s “upstream” supply chain can be diverse, including everything from plastic components and the bioreactors they are used in, to cells, buffers, filters, columns, media, and more. All supplies must be subject to qualified procurement practices as determined and overseen by myriad departments and project managers. Sponsors of marketed products must ensure that they have adequate supplies of a consistent quality of all equipment and materials needed for each product — a true challenge for companies with diverse product portfolios and for contract development and manufacturing organizations (CDMOs) working with products from multiple clients. Raw materials must be available in quantities that will be sufficient for their use where and when they will be needed — but not so much that they waste valuable storage space.

When biopharmaceutical materials — both “upstream” (that is, on the raw materials side) and “downstream” (final products) — must be stored for a time or transported elsewhere, such as to a testing laboratory or manufacturing/distribution facility, environmental conditions must be monitored during transport. These and other logistical elements are critical throughout biopharmaceutical development and manufacturing, and they continue to support a product and the patients who depend on its uninterrupted supply throughout its lifetime and theirs.

Key issues in securing a supply chain include managing costs and consistent quality at development and eventual manufacturing scales, monitoring safety and quality issues for materials used in drug formulations (to prevent adverse patient reactions), knowing what level of quality is needed at what stage for different types of products (a means of controlling costs), ensuring that suppliers provide needed documentation (including having a change-notification process in place), understanding good manufacturing practices (GMPs) and other applicable standards based on a product’s intended use, ensuring traceability of materials, and identifying reliable suppliers (often across borders and regulatory agencies) (1). When it comes to final products, their protection from harm becomes paramount — driven by the needs of patients as well as the value of the products themselves. Important aspects include serialization, tracking and tracing, temperature/humidity control, timing and shipping methods, and even anticounterfeiting efforts.

Industry forces shaping today’s supply-chain management are much the same as those currently transforming other departments (and the biopharmaceutical industry as a whole). Supply-chain managers face

  • an increasing complexity of product portfolios and rising competition, especially for bringing biosimilars and niche formulations to market
  • expanding globalization into emerging regions of bioprocessing
  • the impact of the quality by design (QbD) initiative on advances in real-time monitoring and control of environmental conditions during manufacturing and shipment
  • the emerging stringency of labeling and serialization requirements to ease identification during shipment, storage, and distribution — and also to guard against circulation of counterfeit biopharmaceuticals
  • the establishment of partnerships between manufacturers and suppliers/CDMOs to supply raw-materials and key components throughout a product’s lifetime
  • an upsurge in partnerships for outsourcing drug development and production (in this case, logistics partnerships).

Additionally, most biopharmaceutical formulations must be stored in colder conditions than room temperature, and such key environmental parameters must be maintained throughout shipment and storage at distribution warehouses, pharmacies, and clinics. And the complexity of the supply chain increases for emerging therapies (especially cell/tissue therapies), personalized formulations, and multiproduct manufacturing. Maintaining the necessary storage conditions for drugs with differing environmental needs can place a strain on inventory management.

Two Sides to the Story
BPI’s May 2017 special issue and extended eBook outlined these key points and followed the evolution of supply-chain logistics through a chronological review of BPI articles from 2003 to 2017 (2). We looked at the “ins” of procurement on the upstream side, specific to intake of raw materials and equipment; and the “outs” on the downstream side, specific to final product distribution. For this featured report, we’ve chosen two articles that illustrate how manufacturers of biotherapeutics are addressing specific challenges on each side of the supply chain.

In “Standardizing Human MSCs As Critical Raw Materials in Cell therapy Products: Streamlining Clinical Translation,” Majumder, Olson, and Rowley address what industry analysts have feared would be a major impediment to the success of cell therapies at manufacturing scales: the difficulty of producing the predicted trillions of cells needed for such therapies while (critically) reducing the final costs borne by patients and insurers. Their company, RoosterBio, seeks to disrupt this industry segment by making cells readily available to developers for expansion into multiple product types and classes, thereby eliminating a large portion of the costs of sourcing and internal development. In BPI’s main issue this month, a complementary article details how RoosterBio developed its platform technology.

In “Spray Freeze-Drying Technology: Enabling Flexibility of Supply Chain and Drug-Product Presentation for Biologics,” Lowe, Mehta, and Gupta describe Biogen’s strategy to alleviate risks associated with the need for a complex cold-chain infrastructure by manufacturing biopharmaceutical drug substances as bulk powders. Through a new alternative to the old standby procedure of lyophilization (spray freeze-drying), the potential for long-term, room-temperature stability in dry-powder form could facilitate commercial manufacturing, especially into developing markets.

A Functional Framework
Just a look through titles of supply-chain articles in BPI’s archive (see “For Further Reading,” below) reveals the complexity of supply chain development, maintenance, and security. Whether through cold-chain development and storage, data management, risk assessments, business impacts, quality issues, distribution, particulate control in raw materials, change-control management, and other key components, in parallel with the maturation of the biopharmaceutical industry, those who oversee supply chains also are hoping to work faster, increase safety, and (if possible) decrease the costs of biopharmaceutical medicines. From procurement and quality control of raw materials to distribution and safety of final products, the supply chain provides a framework within which process development, manufacturing, testing, and sales of biopharmaceuticals can function.
