GMP non-compliance can spill over and impact patient access to life-saving medications.
A previously published article (1) reviewed, in depth, the many options FDA has available to escalate the enforcement process when a biopharmaceutical company repeatedly violates the main regulatory standards for ensuring pharmaceutical quality (i.e., 21 Code of Federal Regulations [CFR] Parts 210 and 211, collectively referred to as the current good manufacturing practices [CGMPs]). When a biopharmaceutical company repeatedly violates CGMP requirements, FDA can force it to make specific changes. Under this severe form of escalation by FDA, it’s no longer a discussion about responses to FDA 483 notices or warning letter observations, it’s about a forced make-over. This process, known as Consent Decree (CD), exposes all the broken systems within a company. The impacts of FDA warning letters and CDs extend far beyond the biopharmaceutical company. Today, many times, the impact of a warning letter or CD is discussed only with regard to the effort exerted internally by the biopharmaceutical company to remediate FDA’s enforcement action against itself. This article discusses, in broader context, how non-compliance spills over and impacts the US healthcare system and the consumer.
The US healthcare consumer is older than ever before. From 2012 on, the number of people in the United States turning 65 increased from an annual rate of approximately 2.6 million per year to approximately 3.5 million per year in 2015, a number that is forecasted to rise to nearly 4 million per year over the next decade (2). By 2020, retiring baby boomers will drive Medicare and Medicaid costs to 24% of the United States healthcare budget. As healthcare costs increase faster than economic growth, Medicare taxes and the Trust Fund will cover less and less. In 2016, US healthcare costs were $3.3 trillion. That makes healthcare one of the country’s largest industries, equaling 17.9% of gross domestic product (GDP). In comparison, in 1960, healthcare cost $27.2 billion, or just 5% of GDP (3).
The healthcare consumer is not just the patient, they are caregivers too. More and more people in the US are putting jobs on hold or otherwise impacting their lives to provide medical-related support to someone close to them. On Jan. 22, 2018, the Recognize, Assist, Include, Support, and Engage (RAISE) Family Caregivers Act (4) was signed into law. Providing care for a family member, partner, or friend with a chronic, disabling, or serious health condition, known as “family caregiving”, affects most people at some point in their lives. The need to support family caregivers will grow as the population ages, more people of all ages live with disabilities, and the complexity of care tasks increases. In 2013, about 40 million family caregivers in the US provided an estimated 37 billion hours of care to an adult with limitations in daily activities. The estimated economic value of their unpaid contributions was approximately $470 billion in 2013, up from an estimated $450 billion in 2009 (5).
Healthcare challenges in the US are not geographically blind. The healthcare delivery system in rural America is largely fragmented. The challenges affecting people living in rural areas are different than those affecting people in urban areas (6). These challenges are significant because approximately 51 million, or about 1 in 6, people live in rural areas of the US. The rural population is also older; the rate of growth for seniors living in rural areas has tripled since the 1990s, and if the 80 million baby boomers living in the US continue to follow these migration patterns, the rural population of those age 55 to 75 is set to increase 30% between 2010 and 2020 (6, 7).
Rural Americans have the same issues as other healthcare consumers, only they are more extreme. They tend to have lower incomes, poorer health status, and are less likely to have health coverage through work because there are fewer large employers in rural areas. Consequently, rural consumers also are more likely to be uninsured and more likely to be covered by public rather than private insurance (7). When compared to urban areas, rural areas have higher rates of unemployment and poverty. Recent numbers show rural unemployment averaged 5.4%, while urban unemployment was 4.8% (7).
So, let’s examine some of the ways in which a pharmaceutical company’s failure to manage quality manifests itself outside the company and impacts the American healthcare consumer.
For purposes of this article, non-compliance will equate to FDA enforcement activity (i.e., warning letter or CD) against a biopharmaceutical company in the US. Operating under a warning letter or CD is a dire situation for the company and one where there is no certain predictability of the outcome. To really understand the magnitude of the warning letter’s or CD’s impact, one needs to take into consideration the many and various modes in which the negative consequences can be realized externally and how this impacts the American healthcare consumer.
Figure 1 illustrates the ways in which non-compliance effects can propagate internally and externally to the company. This article focuses on those external effects as they impact the American healthcare consumer. To better understand, think of Figure 1 as a “Tile Slide”. The first three tiles of the first row represent different categories of negative impact to the biopharmaceutical company, while the last tile represents negative impact to the healthcare consumer. Each subsequent tile or row in a column describes a more specific negative effect.
Biopharmaceutical companies manufacture many different drug formulations. Drugs that will be given to a patient by intravenous injection must be manufactured under conditions suitable for human use. They must be manufactured to standards of quality, purity, and sterility that are uncompromising or the patient could be harmed. Interpretation of the GMP guidelines for ensuring integrity of injectable drugs can be a challenge, leading to questioning of how to achieve the standards. The manufacture of sterile injectable pharmaceuticals suitable for human use is complex. Biopharmaceutical manufacturers must ensure the necessary quality parameters described within the United States Pharmacopeia are met. Substandard injectable drugs can arise through inadequate production processes including unintentional use of inferior APIs or excipients, manufacturing processes that cause contamination or do not adequately ensure sterility, and inadequate packaging design or quality. If such medicine left the manufacturing facility it would most certainly be recalled.
The main regulatory standard for ensuring pharmaceutical quality is collectively referred to as the CGMP regulations for human pharmaceuticals. It’s not only the CGMP regulations that matter; how companies interpret and embrace them is of equal, if not more, importance. CGMPs place emphasis on product quality and compliance with the regulations.
FDA’s Office of Regulatory Affairs is the lead office for all field activities, including inspections and enforcement. FDA conducts several types of inspections to help protect consumers from unsafe products: pre-approval inspection, routine inspections of a registered facility, and “for-cause” inspections.
After FDA completes an inspection, company management may receive an FDA Form 483 (8) when an investigator(s) has observed any conditions that, in their judgment, may constitute violations of the Food, Drug, and Cosmetic (FD&C) Act, related Acts, and applicable sections of 21 CFR 210 and 211. Observations are made when in the investigator’s judgment, conditions, or practices observed would indicate that any food, drug, device, or cosmetic has been adulterated or is being prepared, packed, or held under conditions whereby it may become adulterated or rendered injurious to health. FDA Form 483 notifies the company’s management of objectionable conditions. Companies respond to the 483 in writing with their corrective action plan and implement schedule. The 483 is closed when the company receives their establishment inspection report. Unfortunately, there are companies that either do not follow through on their commitments or they do so too slowly. If circumstances merit, FDA can choose to escalate the situation by serving the company with a warning letter.
Typically, FDA’s practice is to give individuals and companies an opportunity to take voluntary and prompt corrective action before it initiates an enforcement action. The warning letter is FDA’s principal means of notifying regulated industry of violations and achieving prompt voluntary correction. Following are some of the factors FDA uses to determine whether to issue a warning letter (9):
Many drug shortages are of sterile injectable drugs and can be traced to supply disruptions caused by company manufacturing facilities slowing or halting production to address quality issues. The number of new shortages has generally decreased since 2011, while the number of ongoing shortages remains high. In 2015, the number of ongoing shortages that began in prior years was up compared to 2014 at 291 and 277, respectively. The number of new shortages being first reported in 2016 was down compared to those reported in 2014 at 136 and 179, respectively (10). Shortages of sterile injectables can be associated with other factors: a decline in the number of manufacturers; failure to comply with CGMP standards, resulting in a warning letter which causes supply disruptions in the first place; and/or prolonged time under warning letter remediation when the manufacturer either cannot manufacturer drugs or the situation warrants that each drug lot must be released only after extensive oversight and review. Another reason is that many of these are generic drugs that can have a relatively low profit margin and manufacturers are less likely to increase production. Regardless the reason, all of these situations only exacerbate already existing supply disruptions.
Characteristics of the sterile injectables industry may make these drugs susceptible to shortage when the number of suppliers decreases. A manufacturer, for example, may decide to permanently discontinue an unprofitable product, or the unavailability of raw materials may lead to production delays. Further, failure to comply with CGMP standards resulting in a warning letter could also trigger a supply disruption if a manufacturer chooses to temporarily shut down production to correct the conditions that led to a warning letter. In this industry, there is limited inventory in the supply chain, manufacturing capacity is constrained because production is scheduled months in advance. New manufacturers must receive regulatory approval before entering the market, and the production process is complex. After a supply disruption for any reason, if other manufacturers are not able to increase supply in a timely manner, a shortage may ensue.
There are specific characteristics of the sterile injectables industry that make these drugs susceptible to shortages (11).
Limited inventory. The use of just-in-time supply demand can increase the vulnerability of the supply chain to shortages. It is not uncommon for manufacturers to have approximately two to three months of inventory available. Wholesale distributors may have one month, and providers may only have a few weeks of inventory. Hence, when a manufacturer stops production, a shortage can result quickly.
Regulatory approval. A new manufacturer could decide to supply the market but usually can’t enter quick enough to produce more drug and remedy the shortage. This is because FDA’s approval of an abbreviated new drug application (ANDA), which is a requirement, can take more than a year. Even if existing manufacturers of the drug could ramp up their own production, they would need FDA approval if changes to manufacturing conditions or processes were made that have a potential to adversely affect the identity, strength, quality, purity, or potency of the drug, before the additional drug manufactured under the new conditions can be marketed.
Manufacturing complexity. Expensive and specialized equipment is required to manufacture drugs, and production processes are complex, particularly for sterile injectables (12). Maintaining sterility throughout the production process is particularly important for sterile injectables because serious harm can occur if non-sterile drugs are injected into patients. Some generic sterile injectables need to be manufactured on lines or in facilities dedicated solely to those drugs, thus creating challenges for new manufacturers to enter the market.
Constrained manufacturing capacity. The generic sterile injectable drug industry is filled with several players. It’s not uncommon for a manufacturer to produce numerous and different drugs on only a few manufacturing lines. As a result, this leaves little flexibility when one manufacturer ceases production of a particular drug. Adding yet more constraint is that many times the production schedule of each drug is planned for up to a year at a time. This leaves little opportunity for sudden changes in production schedule to produce additional quantities of a drug in shortage.
Characteristics of the sterile injectables industry may make these drugs susceptible to shortage when the number of suppliers decreases.
Drug shortages in the US are a serious public health concern and have been for many years. Shortages caught the attention of the US Congress and resulted in a provision in statute for the US Government Accountability Office (GAO) to review several aspects of drug shortages. The period covered was 2010 to 2015, and GAO’s review was published in an extensive report to Congressional committees in July 2016 (10, 13).
Shortages of sterile injectable anti-infective and cardiovascular drugs during 2012, 2013, and 2014 were strongly associated with the following factors: a decrease in the number of manufacturers, sales of a generic version, and the failure of a manufacturer making the drug to comply with CGMPs resulting in a warning letter. For each factor, the GAO report estimated a percentage point increase in the probability of a shortage. Their estimates showed that the presence of a single factor increases the probability of a drug shortage by as much as 16.8 percentage points from what the model otherwise predicted (10). The strong association between shortages and both a decrease in the number of manufacturers and the failure of a manufacturer to comply with CGMPs resulting in a warning letter suggests that shortages may be triggered by supply disruptions.
For the drugs reviewed in the GAO report, the association between noncompliance resulting in a warning letter and shortages is largely driven by the structure of the generic injectable manufacturing industry. In this industry, manufacturers produce multiple drugs, and so one manufacturer’s failure to comply with that results in a warning letter could affect many drugs. For example, 69% of the 118 drugs in the GAO study were manufactured by at least one of nine companies. Thus, if one of these nine companies failed to comply with CGMP standards, many drugs could be affected (14, 15). In 2012, one manufacturer that received a warning letter manufactured 22 drugs just by itself. While the strong association between non-compliance resulting in a warning letter and shortages could support the thought that FDA enforcement triggered some shortages, it could also support the thought that there were growing CGMP problems and possibly related quality concerns that both precipitated the warning letters and led to shortages.
Additionally, the finding that sales of a generic version were associated with shortages suggests that relatively low profit margins may also trigger shortages for sterile injectables. Specifically, compared with drugs for which there were only brand-name sales and thus only one supplier, drugs sold generically may have multiple suppliers and relatively lower profit margins. The 88 drugs in the GAO report sold generically were available from an average of four suppliers during 2013, and 10 drugs had eight or more suppliers. Other researchers have found that prices, and consequently profit margins, decline for generic drugs as the number of suppliers increase (16). Relatively low profit margins may cause manufacturers to exit the market for less profitable drugs in favor of more profitable ones or may make it unprofitable to increase supply, which could make the market vulnerable to shortages.
In US emergency rooms, some of the most common injectable painkillers (e.g., morphine, hydromorphone, and fentanyl) are in short supply. These are first-line choices and vital. What’s challenging is that second-line drugs are out, too. In 2017, half of the medications in drug shortages were for critical care (17). While the majority of the drugs involved in nearly 2000 drug shortages from 2001 to 2016 had an alternative available, one-quarter of the time those alternatives were also on the FDA shortage list. The most common drugs in those shortages were for infectious diseases.
The average length of shortages for drugs used in ambulatory medicine is more than seven months (18). First responders, including some fire departments, have come up with different solutions, including diluting the concentration of a medication on the scene of an emergency and using varying packaging and delivery methods for those drugs (19). They resort to using less potent medication, such as morphine during a fentanyl shortage. Or, it could involve not giving the most basic, benign medication: a saline drip to rehydrate patients or dilute drugs given intravenously. Other ways to address a shortage is to encourage field personnel to provide treatment only when needed as opposed to prophylactic measures (i.e., start the IV if the patient needs the IV, as opposed to starting an IV just in case something should happen) (19).
As for saline, while the smaller 100mL to 500mL bags are in short supply, the larger one-liter bags are used. Or, if they’re being used to deliver medication, it can be given via syringe, although this takes up more of a caregiver’s time. Overall, it’s part of a balance that healthcare providers face in delivering needed medication to patients while still preparing for the unknown: local disasters, epidemics, or even a worsened drug shortage.
When available supplies of prescription drugs are insufficient, patient care may be adversely affected. Drugs in shortage include those that are essential therapies, such as antibiotics, chemotherapy agents, cardiovascular drugs, and pain medications. Shortages can result in delayed patient care and medication errors. They may also result in rationing, which can lead to the use of less effective treatments and force healthcare providers to make difficult choices, such as deciding which cancer patients should start or complete a round of chemotherapy (20). Drug shortages can impair patient care, raise healthcare costs, and hamper clinical trials. Hospitals receive a daily report that shows which drugs are in short supply. In any week, injectable opiates, IV solutions, and a variety of other drugs widely used treatments for heart surgery, dehydration, pain management, nausea, and other ailments compromise nearly all types of care, appear on the drug shortage list.
Emergency physicians must spend more time working around drug shortages. That means they spend less time with the patient, who may receive a more expensive but less effective treatment.
More than one-third of emergency physicians said patient outcomes have been negatively affected as a result. Nearly 90% said they have had to take time away from patients to deal with these shortages while 97% said they had to substitute medications. Drug shortages are expensive (20), and they often lead to mistakes. Providers have had to reconfigure crash carts and other trauma toolkits, which means that it may take longer for first responders to find a drug during an emergency. All this requires thorough staff training, new processes, and constant surveillance.
Drug shortages in America exist for a varying number and combination of reasons that are complex and interrelated. While some of many reasons why drug shortages exist may not be directly linked to non-compliance, it seems that non-compliance is one of the most common reasons that puts things into motion. Ultimately, it is incumbent on the companies and FDA to find new ways to work together to manage these situations before they arise.
