The Wonder Drug for Aging (Made From One of the Deadliest Toxins on Earth)

It’s based on the substance that causes botulism. That’s part of what protects Allergan’s $2.8 billion Botox empire.

There’s no easy way into Allergan’s Botox laboratories in Irvine, Calif. And once you’re inside there’s no quick way out. But first things first: Here’s a waiver acknowledging that within 18 to 36 hours of entering the secured labs, you could develop symptoms including double vision, difficulty speaking, arm or leg weakness, and eventual paralysis of your respiratory system. Try not to worry.

Assume you sign the form and move on. The initial entryway is fitted with keycard-activated doors, beyond which are more doors guarded by PIN pads, followed by still more keycard entry points and more PIN pads. There are only a few people at work or walking around. Deep inside, behind double-paned windows, are still more glass barriers and, finally, metal-enclosed workstations. Everything is under video surveillance. All activity is measured and monitored. Guards watch the comings and goings from a room filled with banks of screens.

All this scrutiny and precaution isn’t there to protect Allergan’s wildly popular drug from competitors, though it is worth protecting—in 2016, Botox generated $2.8 billion in sales. Rather, the security exists because the drug that can take years off a person’s appearance by erasing wrinkles also happens to be made with one of the most toxic substances known to science.

Botox is derived from a toxin purified from Clostridium botulinum, a bacterium that thrives and multiplies in faultily canned food (and sometimes prison-made booze). The botulinum toxin is so powerful that a tiny amount can suffocate a person by paralyzing the muscles used for breathing. It’s considered one of the world’s most deadly potential agents of bioterrorism and is on the U.S. Centers for Disease Control and Prevention’s select agent list of heavily regulated substances that could “pose a severe threat to public, animal or plant health.” Because of that, Allergan must account to the CDC if even a speck of the toxin goes missing, and when it’s sent to Allergan’s manufacturing facility in Ireland, its travels bring to mind a presidential Secret Service operation—minus literally all of the public attention.

A baby-aspirin-size amount of powdered toxin is enough to make the global supply of Botox for a year. That little bit is derived from a larger primary source, which is locked down somewhere in the continental U.S.—no one who isn’t on a carefully guarded list of government and company officials knows exactly where. Occasionally (the company won’t say how frequently), some of the toxin (the company won’t say how much) is shipped in secrecy to the lab in Irvine for research. Even less frequently, a bit of the toxin is transported by private jet, with guards aboard, to the plant in Ireland.

Scientists differ over how much of the toxin would be required to inflict massive damage. Data on the topic is scarce, and that may be intentional. But a study published in 2001 in the Journal of the American Medical Association said that a single gram in crystallized form, “evenly dispersed and inhaled, would kill more than 1 million people.” Experts are divided over what it would take to effectively weaponize the toxin, but the mere possibility of a botulism bomb has the U.S. government on edge. That puts Allergan in a remarkable position. The government’s vigilance enhances the company’s own secrecy, and together they give Botox a near-monopoly that is almost unassailable. Allergan says Botox has more than 90 percent of the market for medical uses of neurotoxins and 75 percent of the market for cosmetic uses. “I used to say, ‘How often do you see that distribution of market share in any category—not just drugs, just in anything?’ ” says David Pyott, chief executive of the company from 1998 to 2015. “People used to laugh and say, ‘I see what you mean,’ because it’s just unheard of.”

There are hundreds of botulism poisonings annually in the U.S. alone, and a couple of times a year someone dies. In a typically random case, a man passed away earlier this year after eating tainted nachos at a gas station outside of Sacramento. It was the cheese sauce.

Around 1820, Justinus Kerner, a German doctor and poet famous for his supernatural and melancholy romantic verse, published the first accurate description of the symptoms of what he termed Wurstgift, or “sausage poisoning”: drooping eyelids, accompanied by difficulty swallowing and breathing. Near the end of the century, a group of musicians playing at a funeral developed double vision and muscle paralysis after eating a ham. At least three died. From that tragedy, Emile Van Ermengem, a microbiology professor in Belgium, identified C. botulinum. He is credited with giving the pathogen its name, deriving it from the Latin word for sausage, “botulus.”

U.S. government concern about the weaponization of botulinum isn’t fanciful. After prodding by United Nations inspectors, Iraq admitted to refining large quantities of the toxin prior to 1991 for use in some of its 25 Al-Husayn warheads, part of a biological weapons program. Earlier, fears that Nazi-era Germany had a stockpile of botulinum led to the development of a vaccination for Allied troops. It was readied in advance of D-day, but intelligence reports ruled out the use of botulism-tipped weapons and the vaccine wasn’t administered. It was also during World War II that the U.S. started studying the toxin for biological weapons of its own, work that indirectly led to the creation of Botox.

Botox is largely the brainchild of two scientists, Alan Scott and Ed Schantz, who approached the toxin with completely different goals. In the 1960s and ’70s, Scott, an ophthalmologist, was looking for a treatment for people with strabismus, or crossed eyes. Schantz’s focus was more military than medical; he’d done work purifying the botulinum toxin in the Chemical Corps at Fort Detrick in Frederick, Md., home of the U.S. biological weapons program, before moving to the University of Wisconsin, where he perfected the process. Schantz became a supplier of the toxin to Scott after a colleague put the two in touch.

Back then, controls for shipping botulinum were next to nonexistent. Schantz sent the stuff, in crystalline form, to Scott via the U.S. Postal Service in a metal tube slipped inside another metal tube. It was Scott who turned the toxin into a pharmaceutical. He then formed a company around his breakthrough, called Oculinum Inc.

The drug, also called Oculinum, was approved in 1989 for strabismus and blepharospasm, or twitchy eyelid. Allergan licensed it from Scott, then bought it outright in 1991. (The name was changed to Botox the next year.) From the start, Allergan took a cautious approach to a substance it recognized had the potential for grave harm if misused. “It’s always been an issue. We’ve certainly known it’s one of the most potent drugs in the world,” says Gavin Herbert Jr., former longtime CEO and son of the company’s co-founder. “It was an issue when we initially made the raw material batches in Irvine and would fly those small batches in a private chartered jet with a security person. We’ve always treated it very carefully.”

Mitchell Brin, Allergan’s chief scientific officer for Botox, has played a critical role in the drug’s development almost from the beginning. In the 1980s he was a neurologist at Columbia University specializing in movement disorders. He and his colleagues got their supply from Scott, who’d gotten U.S. regulatory approval to evaluate the use of his drug on human subjects. Brin began testing it on patients with severe muscle contractions in the face, jaw, neck, and limbs. His awe over its power hasn’t waned—he still enjoys showing old before-and-after films of patients whose spasm disorders were quelled by Botox in some of the earliest days of the drug. His office is like a Botox museum, housing mementos he’s gathered along the way, including a set of matryoshka dolls from a trip to Russia to introduce the drug there. Botox is Brin’s life; he has a California vanity license plate that reads BOTOX.

The drug works like this: A person’s muscles are controlled by motor nerves, which release a chemical that instructs the muscles to contract. Botox blocks the release of that chemical. Today it’s approved for nine different medical uses—including treatment for chronic migraines, overactive bladders, and severe muscle spasms—and is in trials for use in treating depression and is being studied for atrial fibrillation, or AFib. Cosmetic uses are likewise expanding: The next frontier is the saggy neck and the too-square jaw. Herbert says that when Allergan first acquired Botox, he thought it could do $10 million in annual sales. Now it’s on track to grow to almost $4 billion by 2020.


Allergan never set out to become a neurotoxin powerhouse. It got its start in the 1950s mixing batches of anti-allergy nose drops, called Allergan, in a family-run pharmacy in Los Angeles. The co-founder, Gavin Herbert Sr., had also tried and failed to develop a solution to stop thumb-sucking. A friend suggested the company formulate drops to treat allergic conjunctivitis, and Herbert developed the first antihistamine eyedrop in the U.S. It was Allergan’s first big success.

When Herbert Jr. took over in 1957, he moved the company into an old theater. The projection booth was used as a sterile filling area, and the balcony and stage were used for storage. By the 1970s, Allergan was a thriving public company, making eyedrops and contact lens solutions and looking to expand. It was then that Herbert Jr. discovered Westport, Ireland.

At the time, the northwestern coast of Ireland was deep into an economic tailspin, and unemployment in Westport was 30 percent. A local politician persuaded the Westport industrial council to build a factory designed to attract American companies. It stood empty until Herbert showed up. It was tax breaks that first drew him there—he was looking for a second place to make his contact lens solution.

Westport, a town of 6,000, gets its Irish Gaelic name, Cathair na Mart, from a castle that once served as the headquarters for a 16th century pirate queen named Grace O’Malley. Ten years ago she was the subject of a Broadway musical; in Westport today, tour guides tirelessly retell the lore—O’Malley and her ragged band fighting off the British navy and extorting booty from passing merchant ships. Her descendants made up part of the family that planned the modern-day town, with its quaint center surrounded by emerald sheep and cattle farms. Whereas once the economy ran on agriculture and fishing, now it revolves around two other sources. One is tourism: Westport has won Ireland’s coveted Tidy Towns award three times in a decade, an honor “almost unheard of in the modern era of the award,” according to town architect Simon Wall. The other is Botox.


As is often the case with blockbuster drugs, Botox’s story has a chapter on an entirely accidental discovery. It was a doctor couple, Jean Carruthers, a Vancouver ophthalmologist, and her husband, Alastair, a dermatologist, who stumbled on Botox’s anti-aging properties. Jean was treating a patient with eye spasms. The woman protested at one appointment when she wasn’t given a shot in her brow; she said injections in that spot gave her a “beautiful, untroubled expression,” Jean Carruthers recalled in a TEDx Talk in 2012. At the same time, Alastair was looking for a better treatment for deep frown lines. The two teamed up to examine the use of Botox in forehead creases. Their receptionist was the first patient. Within days, she had a smoother forehead and a “refreshed, open, younger expression,” as Jean puts it now. But finding customers willing to be injected in the face with poison wasn’t easy. So Jean decided to use the drug on herself, and soon there was no shortage of takers. “I haven’t frowned since,” she says, laughing.

Full list price for Botox is roughly $600 per treatment, according to the research firm SSR LLC, and this drug sells at full price more often than most. Roughly 55 percent of the business, by revenue, is for medical treatments. The other 45 percent is cosmetic procedures, which aren’t covered by insurance. Patients pay full fare for the drug, plus what their doctor charges to administer it.

Some of the world’s largest pharmaceutical companies have tried and failed to develop their own neurotoxin-based drugs. In 2009, Johnson & Johnson paid $1.1 billion to purchase Mentor Corp., which among other things was developing PurTox, an experimental drug also derived from botulinum. Five years in, J&J stopped work on it. Potential competitors have since been encouraged by the Food and Drug Administration to develop so-called biosimilar drugs, compounds that are almost biologically identical to the reference drug. But no one has taken up the challenge with Botox. Mylan NV, which is in one of the strongest positions of any company to attempt a Botox biosimilar, signaled an interest to investors in March but has not fully committed to trying.

Part of what protects the Botox empire is the sheer complexity of the drug. The recipe isn’t patent-protected—it’s a trade secret, like the formula for Coke. As long as Allergan can protect it, would-be duplicators have to start from scratch. Even if the procedure were out in the open, Brin likens Botox manufacturing to making a fine wine—a winemaker can’t necessarily replicate a rival’s vintage. “The fundamental process is an anaerobic fermentation process,” he says. “The amount of time, the purification process, the reagents that are used with it, these are very, very important, and they’re heavily controlled.”

Allergan was bought in 2015 by Actavis Plc for about $66 billion. Actavis took the Allergan name, a testimony to the strength of the Botox brand. The new company has had its troubles. In 2016, CEO Brent Saunders had emerged as the affable face of an enlightened Big Pharma when he promised to cap drug price increases. That ended in October of that year, when Allergan paid an American Indian tribe, which enjoys sovereign immunity, to hold the intellectual property on its second-biggest drug, the dry-eye treatment Restasis, a move designed to thwart one type of patent challenge. Critics jumped all over Allergan. Bloomberg View’s Joe Nocera labeled it “sleazy … sneaky, unscrupulous, and just plain wrong.” For a profit-minded corporation, this is when it’s especially comforting to have a drug like Botox, whose monopoly is made unassailable by government-assisted operational secrecy.


It’s probably from somewhere near Irvine that the botulinum toxin starts its journey to Westport. The company won’t say where in Ireland the toxin makes landfall or how it makes its way from there to Westport. “It never leaves Allergan’s control,” says Paul Coffey, general manager of Allergan’s Westport facility. “There would be a very small number of people who are aware of the shipment.” And it would be a rare event—there can be a year or more between deliveries.

The company has “no concerns about our security processes despite the madness that’s happening in the world at the moment,” says Coffey. “It just reminds us that if we ever were thinking we didn’t need to have that kind of security, well, yes you do.” As for whether Saunders has ever visited Westport’s most secure production area—or even has the clearance to enter—Coffey answers, “Absolutely not.”

If Saunders were to try, he’d start by turning off one of the few roads that leads out of Westport, looking for a small brown sign that bears the company name. It points down a narrow lane that gives way to a long, winding driveway. The toxin arrives along this lane, through meadows and brilliant gardens, passing by a small building that houses a 24-hour security staff. Beyond that is a campus whose beautiful grounds are a testament to Herbert Jr.’s love of gardening, a facet of both the Westport and Irvine facilities. (Herbert Jr., 85, retired in 1995 and is now an owner of Roger’s Gardens, a home and garden center in Newport Beach, Calif., among other pursuits.)

Coffey likens the security inside the facility to the layers of an onion. “Where we store our purified toxin is in the middle of the onion,” he says. The storage room for the toxin is monitored by cameras that, in addition to guarding the company’s greatest asset, are used to help engineers diagnose equipment problems remotely. The rare few employees who have access to the room do so only after they’ve stripped off their street clothes and suited up in full surgical garb.

From the core of this security onion, the toxin begins its trip back into the world, in a busy plant that employs more than 800 people. The first step in making the drug is to combine saline solution with an almost incomprehensibly minuscule quantity of the purified toxin. The liquid flows through a series of pipes into a sterile filling room. These rooms are monitored for temperature, humidity, differential pressure, nonviable particulates, and other factors. The company takes some 16,000 samples a month across these “cleanrooms” to test for bacteria in the air. Should even a single bacterium show up, an investigation ensues.

It’s a largely automated process that’s tracked by microscopic cameras embedded in the machinery. In the final steps, the saline solution is shot into tiny glass bottles and then reduced to a fine powder. Those bottles, individually boxed, are what doctors around the globe receive. One of the most feared substances on Earth is now largely neutered, immensely valuable, and ready to be injected into a wrinkled brow or a sweaty palm. No need for guarded private jets now. FedEx will do.
