Bio/pharma companies are successfully launching novel therapies; however, the industry still needs to work on manufacturing innovation.
A 2003 Wall Street Journal article noted a pharmaceutical industry “secret;” as the industry developed “futuristic new drugs, its manufacturing techniques lag far behind those of potato-chip and laundry-soap makers” (1). Since that article was written, the introduction of quality-by-design practices, new monitoring technologies, and advances in science and engineering improved some bio/pharma manufacturing processes. In too many cases, however, manufacturing and quality practices are still inadequate or too expensive.
The number of drugs approval by FDA-as well as innovative “firsts” designed to address patient needs-accelerated in the past two years. Following the 2017 approvals of the first cell therapies and gene therapies, 2018 saw the approval of new treatments for infections, the first novel antiviral treatment for the flu in 20 years, the first drug with an indication for treatment of smallpox, the first non-opioid treatment for the management of opioid withdrawal symptoms, and the first drug derived from marijuana.
The upswing in approvals of novel therapies indicates that bio/pharma companies are embracing innovation in R&D. However, analysts report that R&D efforts show diminishing returns. And, the ongoing pace of FDA warning letters, observations, recalls, and drug shortages demonstrates that the bio/pharma industry still has work to do to achieve efficient, cost-effective manufacturing, quality, and analysis to ensure a safe, sufficient drug supply.
A Deloitte/GlobalData study (2) reported that R&D returns at 12 Big Pharma companies hit 1.9% in 2018, the lowest level in nine years, down from 10.1% in 2010. Costs to bring a biopharmaceutical drug to market have almost doubled since 2010 from $1.18 billion to $2.18 billion while forecast peak sales per asset have fallen from $816 million in 2010 to $407 million in 2018, the report notes.
Four small, specialized biopharma companies analyzed for the Deloitte report fared better than the Big Pharma companies, posting returns on R&D of 9.3%; higher development costs ($2.8 billion) were offset by higher anticipated sales ($1.17 billion).
In light of ongoing criticism of the high cost of drugs, raising prices may not be the financial answer; bio/pharma companies need to find innovative ways to improve efficiencies.
In 2016, the number of warning letters issued by FDA for good manufacturing practice infractions doubled and maintained that higher level in 2017 and 2018. The number of drug products recalled by FDA’s Center for Drug Evaluation and Research (CDER) has declined in the past two years; however, the number of recall events increased to the second highest level in the past 10 years (3). While efforts over the past five years have cut the number of new shortages from 251 in 2011 to 35 in 2017, as of Jan. 3, 2019, FDA listed 114 drugs as “currently in shortage” and 207 as discontinued (4).
Recalls of angiotensin II receptor blocker (ARB) drug products from multiple manufacturers-due to the presence of probable human carcinogens traced to API manufacturers-were launched in 2018 and continued in early 2019.
Frustrated with the high cost and chronic shortages of medicines used in hospitals, seven health organizations representing 500 US hospitals formed Civica Rx, a not-for-profit generic drug company; the new organization plans to manufacture 14 hospital-administered generic drugs either directly or through contract manufacturing organizations (5).
The Deloitte study authors stressed the need for a “transformational change” in R&D productivity that uses technology-artificial intelligence, robotic process automation, natural language processing and generation, and machine learning-to replace or augment work done by humans. Partnerships, collaborations, and non-traditional operational models will be necessary to compete in a digital environment and companies will have to compete with non-pharma organizations for the technical talent needed to operate a digitally-driven company.
Many of the predicted applications of information technology focus on drug discovery, clinical trial, and patient monitoring applications. There are, however, opportunities to adopt other new technologies for drug formulation, process development, manufacturing, and supply chain phases.
While bio/pharma companies have demonstrated success at turning out new therapies, the uptake of advanced manufacturing technologies to produce these products, or better ways to manufacture existing products, has been slower.
Manufacturing issues, delays or capacity issues, and loss of manufacturing site account for two-thirds of the causes of drug shortages, FDA reports (6). Capital costs, lost production time for retrofitting, and the need for regulatory review for process changes deter some companies from investing in new technologies for established product lines. For new drug products, the race to get the drug to market is incentive to stick to proven technologies that may not be efficient or cost-effective in the long term.
Some advanced manufacturing technologies-such as continuous manufacturing for solid-dose drugs, 3D printing of drug products, and single-use bioreactors-have demonstrated their effectiveness. Recent FDA approvals of continuous manufacturing processes for oral solid-dose drugs has spurred interest and innovation for advanced manufacturing processes. The Engineering Research Center for Structured Organic Particulate Systems (C-SOPS) at Rutgers University (NJ) works with industry and FDA to modernize pharmaceutical manufacturing processes focusing on continuous processing with predictive control and the next generation of dosage forms.
“There is a lot of technology out there, but the largest challenge remains in bringing it all together in a timely and cost-effective manner,” says Douglas B. Hausner, associate director of C-SOPS. “This is a challenge with modern advanced methods that have greater complexity and require greater upfront effort and investment to then run smoothly thereafter. Much of this pertains to software, sensor, and control integration. Some companies are looking to form partnerships and ‘pre-integrate’ where possible to minimize this.”
Many technological advances and materials are needed to reduce the costs of biopharmaceutical manufacturing, says Ruben G. Carbonell, chief technology officer at the National Institute for Innovation in Manufacturing Biopharmaceuticals (NIIMBL), a public-private partnership that advances biopharmaceutical manufacturing innovation and workforce development. In-line process analytical technology (PAT) for product quality and process control is one of the areas of greatest need, to enable continuous and hybrid processes, he says.
Automated bioreactors and purification processes for cell-therapy manufacturing; rapid adventitious agent (AA) detection and novel materials for viral clearance; and other technologies to reduce release times for biotherapeutics are other areas of need. The availability of advanced technologies does not necessarily mean they are widely adopted, however. For example, “significant advances are being made in rapid AA detection utilizing next generation screening that are yet not being broadly throughout the industry,” Carbonell says.
Bio/pharma companies operate in a regulated environment and face pressures to control end-product prices while driving investor return on costly R&D efforts. The tendency to take a conservative approach to the adoption of new technologies or materials is not surprising.
“There are significant efforts within large biopharma companies and suppliers in the testing and evaluation of novel approaches to cost-effective manufacturing,” says Carbonell. “Adoption of these technologies has been slow because of perceived risks of not being approved for new products or processes.”
Hausner notes that when assessing new technologies or processes to advance drug production, companies are initially cautious and calculated, skeptical of regulatory acceptance, followed by enthusiasm and looking for rapid solutions and regulatory clarity.
“Given the significant costs associated with biopharmaceutical products, it is not surprising that biopharma companies take a conservative approach to innovation because they strive to ensure acceptance by regulatory agencies,” says Carbonell. “One of the main barriers to adoption of new technologies is indeed the perceived risk of not achieving regulatory acceptance. The biopharma industry, manufacturers and suppliers, should work side by side with regulatory agencies to evaluate new technologies to ensure rapid adoption.”
“There is the obvious financial cost/benefit and the fact that unknowns and unproven tech are always harder, but beyond this it often seems to come down to organizational readiness,” says Hausner. “Many new technologies are complex and require additional expertise often in the form of new hires or at least vendor/consultant relationships. There needs to be true organizational buy in for an advanced integrated technology. It can be much closer to buying or building a new plant than a new piece of hardware like a tablet press.”
FDA actively encourages the adoption of advanced manufacturing processes. In 2014, the agency initiated an Emerging Technology Program, which enables meetings between drug development companies and FDA Emerging Technology Team members to address potential concerns about a novel technology prior to filing a regulatory submission.
The agency also issued guidance on emerging technologies and promotes the adoption of advanced technologies at industry meetings. A broader effort by the agency is needed, however, wrote FDA Commissioner Scott Gottlieb in a July 2018 blog (7).
“The bottom line is this: drug makers won’t switch to these systems until we create a clear path toward their adoption and provide more regulatory certainty that changing over to a new manufacturing system won’t be an obstacle to either new or generic-drug approvals,” wrote Gottlieb. “The FDA recognizes that it’ll require additional investment in policies and programs that’ll provide regulatory clarity to enable these new methods to be more quickly and widely adopted.”
The fiscal year 2019 budget includes $58 million to accelerate the development of the regulatory and scientific architecture, Gottlieb wrote. In August 2018, the agency issued nearly $6 million in grants to study improvements to continuous manufacturing, monitoring, and control techniques (8). An additional $2.4 million in grants were awarded to six universities to investigate improvements to continuous manufacturing for biologic-based drugs (9).
Although the complexities of drug manufacturing may exceed that of other industries-including snack foods and laundry soaps-can bio/pharma learn from other industries about adopting new technologies?
Pre-competitive efforts have paid off in other industries, explained Carbonell. “Years ago, the microelectronics industry created large, pre-competitive non-profit consortia of manufacturers, academic and research institutions, and government agencies to evaluate new technologies, such as SEMATECH, to standardize and harmonize equipment, connectors, and measurement devices and approaches,” he said. “These efforts played a key role in reducing costs and advancing the chip manufacturing industry in the US.”
“Pre-competitive industry organizations play a major role by helping to inform the public consensus on new technology. This aids in regulatory understanding, acceptance, and approval,” says Hausner. “These groups perform a soft harmonization on technology and nomenclature ahead of more official groups like regulatory bodies and standard-setting organizations.”
“Industry-university-non profit-government consortia such as NIIMBL can play a key role in accelerating the adoption of novel manufacturing approaches. New technologies that show promise in the laboratory can be tested and de-risked in an industrial setting taking into account regulatory expectations,” said Carbonell. “These consortia reduce the costs of technology development and significantly reduce the risk to an individual company of developing a new approach that may not be approved because it is not broadly accepted.”
