ANN ARBOR, Mich. — Despite the jackhammer-like rhythm of a mechanical ventilator, Alicia Moreno had dozed off in a chair by her 1-year-old’s hospital bed. Then her doctor woke her with some bad news: The common stool softener her son, Anderson, was given months earlier had been contaminated with the bacterium Burkholderia cepacia.
Suddenly, Anderson’s rocky course made medical sense. B. cepacia was the same unusual bacterium mysteriously found in the boy’s respiratory tract, temporarily taking him off the list for a heart transplant. The same bacterium resurfaced after his transplant and combined with a flulike illness to infect his lungs. He’s been on a ventilator ever since.
The tainted over-the-counter medicine, docusate sodium, routinely prescribed to nearly every hospitalized patient to avert constipation caused Anderson to suffer “serious and dangerous life-threatening injuries,” a lawsuit filed by his family alleges. The drug was eventually recalled, but only after a Texas hospital staffer noticed an uptick in B. cepacia infections, prompting a six-month investigation that led back to the tainted drug and its Florida manufacturing plant.
“Something that was supposed to help him hurt him,” Moreno said.
Since the start of 2013, pharmaceutical companies based in the U.S. or abroad have recalled about 8,000 medicines, comprising billions of tablets, bottles and vials that have entered the U.S. drug supply and made their way to patients’ medicine cabinets, hospital supply closets and IV drips, a Kaiser Health News investigation shows. The recalls represent a fraction of the medicines shipped each year. But the flawed products contained a variety of contaminants, including dangerous bacteria, tiny glass particles and mold — or too much or too little of the drug’s active ingredient.
Something that was supposed to help him hurt him.
Over the same period, 65 drugmaking facilities recalled nearly 300 products within 12 months of passing a Food and Drug Administration inspection — as was the case with the stool softener, according to a KHN analysis of recall notices and inspection records kept by the FDA.
Those recalls included more than 39,000 bottles of the HIV drug Atripla laced with “red silicone rubber particulates,” nearly 37,000 generic Abilify mood disorder tablets that were “superpotent,” and nearly 12,000 boxes of generic Aleve (naproxen) that were actually ibuprofen, according to the recall data KHN examined.
The medicine alleged to have sickened Anderson Moreno seriously infected at least 62 other people in 12 states in 2016, according to reports by the FDA and the Centers for Disease Control and Prevention. The drug was made at a PharmaTech plant in Broward County, Florida. That same plant passed an FDA inspection even while it was making bacteria-laced products, according to a KHN review of the inspection records.
PharmaTech did not respond to KHN’s requests for comment. A lawyer for the drugmaker filed a motion to dismiss the lawsuit in April, but it was not granted. In follow-up court records, PharmaTech has denied claims against it.
Like other FDA commissioners before him, Scott Gottlieb has called his agency’s drug oversight program the “gold standard” for safety and effectiveness.
But veteran industry consultant John Avellanet, who has trained FDA inspectors, questions how effective the FDA’s drug plant inspections actually are. “It’s so easy” for FDA inspectors to miss things because they’re working with confusing regulatory terms and standards that are often decades out of date, Avellanet said.
Just how often people are sickened or die from tainted drugs is next to impossible to determine. No government agency tracks cases unless they’re linked to a major outbreak among hospital patients. And sudden, seemingly random illnesses in disparate places are notoriously hard to link to a tainted drug. That’s in part because drugmakers don’t have to divulge which products are made in which manufacturing plants, since that is regarded as proprietary information.
The result: Even someone who buys drugs for a major hospital can’t track down where a potentially dangerous product came from, said Erin Fox, who purchases medicines for University of Utah Health hospitals.
“Patient safety should come first,” she said, adding that the KHN analysis indicates “our drug quality is probably not what we think it is,” and calling it a “scary” reality. “Something does need to change if this is happening this many times and we’re having patients receiving contaminated products.”
The FDA declined to be interviewed for this article, but responded to written questions.
“While the FDA would prefer that no drug be distributed that later is recalled, we do not think that a recall indicates a failure of FDA inspection and surveillance programs,” FDA spokesman Jeremy Kahn said in an email. He said that inspectors “may not uncover all issues or practices that may eventually result in a problem leading to a recall” and that “not all recalls are the result of poor manufacturing practice.”
The PharmaTech Story
“Lucky fin, lucky fin, lucky fin,” Alicia Moreno, 30, cheered as she untangled her now 3-year-old son’s stroke-weakened arm from a sweater and his portable ventilator in the back seat of the car for yet another four-hour drive to see doctors in Ann Arbor. In the Disney movie “Finding Nemo,” Nemo’s father calls the young fry’s smaller fin his “lucky fin.”
While her husband drives, Alicia pulls out a clear plastic case of syringes and watches the clock on the dashboard. Anderson needs about two dozen different medicines every 24 hours, and Alicia administers them via a port in his belly at designated times.
It wasn’t always like this. Anderson appeared healthy until his six-month checkup in May 2016, his mother said. Partway through the exam, the Morenos rushed their baby to a nearby hospital and learned that he was in heart failure and would need a transplant to survive. That’s where he received the tainted stool softener, his lawyers allege. The hospital where Anderson eventually received his transplant confirmed via email that Anderson tested positive for the same strain of B. cepacia involved in the outbreak traced back to PharmaTech’s contaminated drug.
In July, according to the family, Anderson started to have difficulty breathing and his temperature spiked to 106 degrees, which landed him in the intensive-care unit, where doctors and nurses packed him with ice and rushed to find the cause. Their tests turned up positive for B. cepacia, a bacterium found in untreated water that doesn’t typically make healthy people sick. Anderson’s status on the transplant list was put on hold, and his heart condition worsened. He was placed on a machine that transferred blood outside his body, oxygenated it and pumped it back in.
Anderson finally got a heart transplant in November 2016, but four days after doctors closed his chest, his fever was back and his lungs kept getting worse, requiring more complicated machinery. Tests came back positive for a flulike virus and B. cepacia, according to the hospital.
“Where did he get it?” his parents pleaded. At the time, no one knew.
How Tainted Drugs Slip Through the Cracks
The FDA is supposed to inspect all factories, foreign and domestic, that produce drugs for the U.S. market. But a KHN review of thousands of FDA documents — inspection records, recalls, warning letters and lawsuits — offers insight into the ways poorly manufactured or contaminated drugs reach consumers: Inspectors miss serious hazards. Drugmakers fail to meet standards even after the FDA has taken enforcement action. Hundreds of plants haven’t been inspected for years, if ever.
Last July, for example, the FDA announced the first of many voluntary recalls of the blood pressure medicine valsartan because some tablets contain a cancer-causing impurity called N-nitrosodimethylamine, or NDMA. They would later find a similar carcinogen, N-nitrosodiethylamine in valsartan pills. Over the prior two years, investigators had detected worrisome problems in two overseas factories involved in the manufacturing of the drug.
In 2017, FDA investigators found rust, chipping paint and deteriorating equipment at a plant run by Zhejiang Huahai Pharmaceutical Co. in Zhejiang, China. Plant staffers weren’t properly testing and investigating “anomalies” in their drugs, dismissing problematic test results, the FDA said at that time. Inspectors also found “black metallic particles” and other problems in some unidentified drugs.
The FDA inspected the plant in July 2018 after complaints about NDMA from a facility further down the drug supply chain. The FDA put the facility on import alert in late September and issued a warning letter in November detailing deficiencies, including “failure of your quality unit to ensure that quality-related complaints are investigated and resolved.”
At a facility of Hetero Labs in India, in 2016, FDA inspectors found colored and white residue in components. They also discovered that some of the factory’s tablets were twice as thick as others and that employees were shredding documents in the middle of the night. The FDA issued a warning letter to the company as a result of the inspection.
Plants making drugs for U.S. consumers are supposed to be inspected every few years, according to a risk-based system. However, in the past decade more than 2,500 facilities, both foreign and domestic, have gone more than five years without an FDA drug-quality inspection, a KHN analysis found. The FDA has no drug-quality inspection records over the past decade for more than 1,200 domestic plants and nearly 400 foreign plants, excluding those that make animal drug products, according to the analysis. Gottlieb said in December that he hopes to clear the backlog of uninspected drug facilities by the end of September.
At best, the inspections are a snapshot in time, and involve looking at processes rather than evaluating the drugs themselves, said drug-quality specialist Dinesh Thakur, who has worked for drugmakers. The inspections might take place while the facility is making only one of a dozen or so drugs that it usually manufactures.
“The implicit assumption … is that if the [manufacturing] processes are sound, the product will be of good quality,” said Thakur, who raised the alarm about quality-control problems at generics drugmaker Ranbaxy, resulting in a 2013 guilty plea and a $500 million settlement. “Your data tells us this is not true.”
Many inspections, he said, are “stage-managed,” so that factories pass on the appointed day, but “once the inspectors leave, it’s a completely different story.”
David Gortler, a former FDA medical officer, said most drug plant inspections involve looking over paper records and trusting that they’re real, instead of randomly testing medicines.
“Anybody can write down anything on a piece of paper,” said Gortler, who is now a consultant at FormerFDA.com. He added that FDA inspectors aren’t reprimanded — or even told — if they’ve passed a plant that issued a recall shortly thereafter.
A Lucky Break Solves A Mystery
The contaminated stool softener alleged to have sickened Anderson Moreno was one of many drugs recalled by plants shortly after they passed an FDA inspection. The bacteria was detected only after an outbreak of disease — and after a good deal of medical sleuthing.
More than 1,000 miles away from Anderson’s ICU bed in Michigan, staffers at Texas Children’s Hospital’s pediatric ICU in Houston had diagnosed three cases of B. cepacia in one week in February 2016, according to a 2017 medical journal article published in Infection Control and Hospital Epidemiology. It was odd because there had been no cases the previous year.
Hospital staff members embarked on a months-long investigation and by July had identified 24 victims, whose median age was under 2 years old. Patients had the same strain of the bacteria in their blood, their respiratory tracts, their urine or their stool, according to the article.
Samples matched the bacteria found in liquid docusate, the stool softener, the researchers wrote.
The hospital alerted the CDC and other public health officials of its findings. The CDC would eventually identify 63 confirmed and 45 suspected serious B. cepacia infections in 12 states tied to the contaminated drug.
A 36-day FDA inspection of PharmaTech in Davie, Florida, that ended Aug. 9, 2016, revealed that the bacteria was in water used to clean equipment and make liquid products. FDA inspectors concluded that the bacterium made it into the facility’s drugs starting in 2015 and was still present in the water.
Anderson was treated with the stool softener in May 2016. His parents filed a lawsuit in September 2017 against the drugmaker and others in the drug supply chain, alleging that the drug was contaminated and caused him grievous damage. PharmaTech, which did not return KHN’s requests for comment, unsuccessfully filed a motion to dismiss and has denied all charges in a subsequent filing.
A 9-month-old girl in Pittsburgh who had received the stool softener died on May 4, 2016, according to a wrongful-death lawsuit her family filed in July 2017 against PharmaTech and others in the drug supply chain. The court rejected PharmaTech’s motions to dismiss, and the drugmaker denied liability in a subsequent filing.
According to federal records, FDA inspectors had a chance to catch the contamination during their March 2016 inspection, but the PharmaTech plant passed with no citations. PharmaTech CEO Ray Figueroa saluted the inspection results in a press release, calling it “a testimony to PharmaTech’s commitment to world-class quality.”
How Things Can Go Wrong
The FDA has issued thousands of enforcement actions against drug plants over the years, citing safety violations, issuing warning letters and blocking imports from certain foreign plants. In rare cases, the FDA can also seize drug products and has done so 23 times in the past decade. The last drug seizure was more than two years ago, according to FDA records.
In an emailed statement, FDA chief Gottlieb said the FDA is “taking new steps” to identify problems before they occur and it is “not shy” to use its powers to mitigate risks.
But the system can be stymied or gamed, and the FDA’s enforcement abilities are limited. For instance, it doesn’t have the power to issue a mandatory recall, and manufacturing citations don’t come with fines.
Many cases come to light only when a whistleblower sounds an alarm.
Thakur, the Ranbaxy whistleblower, said officials in other countries sometimes tip off plants about “surprise” FDA inspections. And FDA inspectors often have to rely on translators hired by the drug companies, said Avellanet, who has been a drug facility inspection consultant for more than 20 years.
