‘A Devil’s Bargain’: Why Pharmacy Benefit Managers Are Sticking with Humira

By Arthur Allen, KFF Health News

Tennessee last year spent $48 million on a single drug, Humira — about $62,000 for each of the 775 patients who were covered by its employee health insurance program and receiving the treatment. So when nine Humira knockoffs, known as biosimilars, hit the market for as little as $995 a month, the opportunity for savings appeared ample and immediate.

But it isn’t here yet. Makers of biosimilars must still work within a health care system in which basic economics rarely seems to hold sway.

For real competition to take hold, the big pharmacy benefit managers, or PBMs, the companies that negotiate prices and set the prescription drug menu for 80% of insured patients in the United States, would have to position the new drugs favorably in health plans.

They haven’t, though the logic for doing so seems plain.

Humira has enjoyed high-priced U.S. exclusivity for 20 years. Its challengers could save the health care system $9 billion and herald savings from the whole class of drugs called biosimilars — a windfall akin to the hundreds of billions saved each year through the purchase of generic drugs.

The biosimilars work the same way as Humira, an injectable treatment for rheumatoid arthritis and other autoimmune diseases. And countries such as the United Kingdom, Denmark, and Poland have moved more than 90% of their Humira patients to the rival drugs since they launched in Europe in 2018.

Kaiser Permanente, which oversees medical care for 12 million people in eight U.S. states, switched most of its patients to a biosimilar in February and expects to save $300 million this year alone.

Biosimilars Are Cheaper

Biologics — both the brand-name drugs and their imitators, or biosimilars — are made with living cells, such as yeast or bacteria. With dozens of biologics nearing the end of their patent protection in the next two decades, biosimilars could generate much higher savings than generics, said Paul Holmes, a partner at Williams Barber Morel who works with self-insured health plans. That’s because biologics are much more expensive than pills and other formulations made through simpler chemical processes.

For example, after the first generics for the blockbuster anti-reflux drug Nexium hit the market in 2015, they cost around $10 a month, compared with Nexium’s $100 price tag. Coherus BioSciences launched its Humira biosimilar, Yusimry, in July at $995 per two-syringe carton, compared with Humira’s $6,600 list price for a nearly identical product.

“The percentage savings might be similar, but the total dollar savings are much bigger,” Holmes said, “as long as the plan sponsors, the employers, realize the opportunity.”

That’s a big if.

While a manufacturer may need to spend a few million dollars to get a generic pill ready to market, makers of biosimilars say their development can require up to eight years and $200 million. The business won’t work unless they gain significant market share, they say.

The biggest hitch seems to be the PBMs. Express Scripts and Optum Rx, two of the three giant PBMs, have put biosimilars on their formularies, but at the same price as Humira. That gives doctors and patients little incentive to switch. So Humira remains dominant for now.

“We’re not seeing a lot of takeup of the biosimilar,” said Keith Athow, pharmacy director for Tennessee’s group insurance program, which covers 292,000 state and local employees and their dependents.

The ongoing saga of Humira — its peculiar appeal to drug middlemen and insurers, the patients who’ve benefited, the patients who’ve suffered as its list price jumped sixfold since 2003 — exemplifies the convoluted U.S. health care system, whose prescription drug coverage can be spotty and expenditures far more unequal than in other advanced economies.

Biologics like Humira occupy a growing share of U.S. health care spending, with their costs increasing 12.5% annually over the past five years. The drugs are increasingly important in treating cancers and autoimmune diseases, such as rheumatoid arthritis and inflammatory bowel disease, that afflict about 1 in 10 Americans.

Humira’s $200 billion in global sales make it the best-selling drug in history. Its manufacturer, AbbVie, has aggressively defended the drug, filing more than 240 patents and deploying legal threats and tweaks to the product to keep patent protections and competitors at bay.

The company’s fight for Humira didn’t stop when the biosimilars finally appeared. The drugmaker has told investors it doesn’t expect to lose much market share through 2024. “We are competing very effectively with the various biosimilar offerings,” AbbVie CEO Richard Gonzalez said during an earnings call.

How AbbVie Maintains Market Share

One of AbbVie’s strategies was to warn health plans that if they recommended biosimilars over Humira they would lose rebates on purchases of Skyrizi and Rinvoq, two drugs with no generic imitators that are each listed at about $120,000 a year, according to PBM officials. In other words, dropping one AbbVie drug would lead to higher costs for others.

Industry sources also say the PBMs persuaded AbbVie to increase its Humira rebates — the end-of-the-year payments, based on total use of the drug, which are mostly passed along by the PBMs to the health plan sponsors. Although rebate numbers are kept secret and vary widely, some reportedly jumped this year by 40% to 60% of the drug’s list price.

The leading PBMs — Express Scripts, Optum, and CVS Caremark — are powerful players, each part of a giant health conglomerate that includes a leading insurer, specialty pharmacies, doctors’ offices, and other businesses, some of them based overseas for tax advantages.

Yet challenges to PBM practices are mounting. The Federal Trade Commission began a major probe of the companies last year. Kroger canceled its pharmacy contract with Express Scripts last fall, saying it had no bargaining power in the arrangement, and, on Aug. 17, the insurer Blue Shield of California announced it was severing most of its business with CVS Caremark for similar reasons.

Critics of the top PBMs see the Humira biosimilars as a potential turning point for the secretive business processes that have contributed to stunningly high drug prices.

Although list prices for Humira are many times higher than those of the new biosimilars, discounts and rebates offered by AbbVie make its drug more competitive. But even if health plans were paying only, say, half of the net amount they pay for Humira now — and if several biosimilar makers charged as little as a sixth of the gross price — the costs could fall by around $30,000 a year per patient, said Greg Baker, CEO of AffirmedRx, a smaller PBM that is challenging the big companies.

Multiplied by the 313,000 patients currently prescribed Humira, that comes to about $9 billion in annual savings — a not inconsequential 1.4% of total national spending on pharmaceuticals in 2022.

The launch of the biosimilar Yusimry, which is being sold through Mark Cuban’s Cost Plus Drugs pharmacy and elsewhere, “should send off alarms to the employers,” said Juliana Reed, executive director of the Biosimilars Forum, an industry group. “They are going to ask, ‘Time out, why are you charging me 85% more, Mr. PBM, than what Mark Cuban is offering? What is going on in this system?’”

Cheaper drugs could make it easier for patients to pay for their drugs and presumably make them healthier. A KFF survey in 2022 found that nearly a fifth of adults reported not filling a prescription because of the cost. Reports of Humira patients quitting the drug for its cost are rife.

Inflated Sticker Prices

When Sue Lee of suburban Louisville, Kentucky, retired as an insurance claims reviewer and went on Medicare in 2017, she learned that her monthly copay for Humira, which she took to treat painful plaque psoriasis, was rising from $60 to $8,000 a year.

It was a particularly bitter experience for Lee, now 81, because AbbVie had paid her for the previous three years to proselytize for the drug by chatting up dermatology nurses at fancy AbbVie-sponsored dinners. Casting about for a way to stay on the drug, Lee asked the company for help, but her income at the time was too high to qualify her for its assistance program.

“They were done with me,” she said. Lee went off the drug, and within a few weeks the psoriasis came back with a vengeance. Sores covered her calves, torso, and even the tips of her ears. Months later she got relief by entering a clinical trial for another drug.

Health plans are motivated to keep Humira as a preferred choice out of convenience, inertia, and fear. While such data is secret, one Midwestern firm with 2,500 employees told KFF Health News that AbbVie had effectively lowered Humira’s net cost to the company by 40% after July 1, the day most of the biosimilars launched.

One of the top three PBMs, CVS Caremark, announced in August that it was creating a partnership with drugmaker Sandoz to market its own cut-rate version of Humira, called Hyrimoz, in 2024. But Caremark didn’t appear to be fully embracing even its own biosimilar. Officials from the PBM notified customers that Hyrimoz will be on the same tier as Humira to “maximize rebates” from AbbVie, Tennessee’s Athow said.

Most of the rebates are passed along to health plans, the PBMs say. But if the state of Tennessee received a check for, say, $20 million at the end of last year, it was merely getting back some of the $48 million it already spent.

“It’s a devil’s bargain,” said Michael Thompson, president and CEO of the National Alliance of Healthcare Purchaser Coalitions. “The happiest day of a benefit executive’s year is walking into the CFO’s office with a several-million-dollar check and saying, ‘Look what I got you!’”

Executives from the leading PBMs have said their clients prefer high-priced, high-rebate drugs, but that’s not the whole story. Some of the fees and other payments that PBMs, distributors, consultants, and wholesalers earn are calculated based on a drug’s price, which gives them equally misplaced incentives, said Antonio Ciaccia, CEO of 46Brooklyn, a nonprofit that researches the drug supply chain.

“The large intermediaries are wedded to inflated sticker prices,” said Ciaccia.

AbbVie has warned some PBMs that if Humira isn’t offered on the same tier as biosimilars it will stop paying rebates for the drug, according to Alex Jung, a forensic accountant who consults with the Midwest Business Group on Health.

AbbVie did not respond to requests for comment.

One of the low-cost Humira biosimilars, Organon’s Hadlima, has made it onto several formularies, the ranked lists of drugs that health plans offer patients, since launching in February, but “access alone does not guarantee success” and doesn’t mean patients will get the product, Kevin Ali, Organon’s CEO, said in an earnings call in August.

If the biosimilars are priced no lower than Humira on health plan formularies, rheumatologists will lack an incentive to prescribe them. When PBMs put drugs on the same “tier” on a formulary, the patient’s copay is generally the same.

In an emailed statement, Optum Rx said that by adding several biosimilars to its formularies at the same price as Humira, “we are fostering competition while ensuring the broadest possible choice and access for those we serve.”

Switching a patient involves administrative costs for the patient, health plan, pharmacy, and doctor, said Marcus Snow, chair of the American College of Rheumatology’s Committee on Rheumatologic Care.

Doctors Reluctant to Switch

Doctors seem reluctant to move patients off Humira. After years of struggling with insurance, the biggest concern of the patient and the rheumatologist, Snow said, is “forced switching by the insurer. If the patient is doing well, any change is concerning to them.” Still, the American College of Rheumatology recently distributed a video informing patients of the availability of biosimilars, and “the data is there that there’s virtually no difference,” Snow said. “We know the cost of health care is exploding. But at the same time, my job is to make my patient better. That trumps everything.”

“All things being equal, I like to keep the patient on the same drug,” said Madelaine Feldman, a New Orleans rheumatologist.

Gastrointestinal specialists, who often prescribe Humira for inflammatory bowel disease, seem similarly conflicted. American Gastroenterological Association spokesperson Rachel Shubert said the group’s policy guidance “opposes nonmedical switching” by an insurer, unless the decision is shared by provider and patient. But Siddharth Singh, chair of the group’s clinical guidelines committee, said he would not hesitate to switch a new patient to a biosimilar, although “these decisions are largely insurance-driven.”

HealthTrust, a company that procures drugs for about 2 million people, has had only five patients switch from Humira this year, said Cora Opsahl, director of the Service Employees International Union’s 32BJ Health Fund, a New York state plan that procures drugs through HealthTrust.

But the biosimilar companies hope to slowly gain market footholds. Companies like Coherus will have a niche and “they might be on the front end of a wave,” said Ciaccia, given employers’ growing demands for change in the system.

The $2,000 out-of-pocket cap on Medicare drug spending that goes into effect in 2025 under the Inflation Reduction Act could spur more interest in biosimilars. With insurers on the hook for more of a drug’s cost, they should be looking for cheaper options.

For Kaiser Permanente, the move to biosimilars was obvious once the company determined they were safe and effective, said Mary Beth Lang, KP’s chief pharmacy officer. The first Humira biosimilar, Amjevita, was 55% cheaper than the original drug, and she indicated that KP was paying even less since more drastically discounted biosimilars launched. Switched patients pay less for their medication than before, she said, and very few have tried to get back on Humira.

Prescryptive, a small PBM that promises transparent policies, switched 100% of its patients after most of the other biosimilars entered the market July 1 “with absolutely no interruption of therapy, no complaints, and no changes,” said Rich Lieblich, the company’s vice president for clinical services and industry relations.

AbbVie declined to respond to him with a competitive price, he said.

Biosimilar Drugs Are Cheaper Than Biologics, But Are They as Effective?

By Michelle Andrews, Kaiser Health News  

It took years for Elle Moxley to get a diagnosis that explained her crippling gastrointestinal pain, digestion problems, fatigue, and hot, red rashes. And after learning in 2016 that she had Crohn’s disease, a chronic inflammation of the digestive tract, she spent more than four years trying medications before getting her disease under control with a biologic drug called Remicade.

So Moxley, 33, was dismayed to receive a notice from her insurer in January that Remicade would no longer be covered as a preferred drug on her plan. Another drug, Inflectra, which the Food and Drug Administration says has no meaningful clinical differences from Remicade, is now preferred. It is a “biosimilar” drug.

“I felt very powerless,” said Moxley, who recently started a job as a public relations coordinator for Kansas City Public Schools in Missouri. “I have this decision being made for me and my doctor that’s not in my best interest, and it might knock me out of remission.”

After Moxley’s first Inflectra infusion in July, she developed a painful rash. It went away after a few days, but she said she continues to feel extremely fatigued and experiences gastrointestinal pain, constipation, diarrhea and nausea.

Many medical professionals look to biosimilar drugs as a way to increase competition and give consumers cheaper options, much as generic drugs do, and they point to the more robust use of these products in Europe to cut costs.

ELLE MOXLEY

Yet the U.S. has been slower to adopt biosimilar drugs since the first such medicine was approved in 2015. That’s partly because of concerns raised by patients like Moxley and their doctors, but also because brand-name biologics have kept biosimilars from entering the market. The companies behind the brand-name drugs have used legal actions to extend the life of their patents and incentives that make offering the brand biologic more attractive than offering a biosimilar on a formulary, listing which drugs are covered on an insurance plan.

“It distorts the market and makes it so that patients can’t get access,” said Dr. Jinoos Yazdany, a professor of medicine and chief of the rheumatology division at Zuckerberg San Francisco General Hospital.

The FDA has approved 31 biosimilar medications since 2015, but only about 60% have made it to market, according to an analysis by NORC, a research organization at the University of Chicago.

Remicade’s manufacturer, Johnson & Johnson, and Pfizer, which makes the Remicade biosimilar Inflectra, have been embroiled in a long-running lawsuit over Pfizer’s claims that Johnson & Johnson tried to choke off competition through exclusionary contracts with insurers and other anti-competitive actions. In July, the companies settled the case on undisclosed terms.

In a statement, Pfizer said it would continue to sell Inflectra in the U.S. but noted ongoing challenges:

“Pfizer has begun to see progress in the overall biosimilars marketplace in the U.S. However, changes in policy at a government level and acceptance of biosimilars among key stakeholders are critical to deliver more meaningful uptake so patients and the healthcare system at-large can benefit from the cost savings these medicines may deliver.”

Johnson & Johnson said it is committed to making Remicade available to patients who choose it, which “compels us to compete responsibly on both price and value.”

‘Highly Similar’ Drugs

Biologic medicines, which are generally grown from living organisms such as animal cells or bacteria, are more complex and expensive to manufacture than drugs made from chemicals. In recent years, biologic drugs have become a mainstay of treatment for autoimmune conditions like Crohn’s disease and rheumatoid arthritis, as well as certain cancers and diabetes, among other conditions.

Other drugmakers can’t exactly reproduce these biologic drugs by following chemical recipes as they do for generic versions of conventional drugs.

Instead, biosimilar versions of biologic drugs are generally made from the same types of materials as the original biologics and must be “highly similar” to them to be approved by the FDA. They must have no clinically meaningful differences from the biologic drug, and be just as safe, pure and potent. More than a decade after Congress created an approval pathway for biosimilars, they are widely accepted as safe and effective alternatives to brand biologics.

Medical experts hope that as biosimilars become more widely used they will increasingly provide a brake on drug spending.

From 2015 to 2019, drug spending overall grew 6.1%, while spending on biologics grew more than twice as much — 14.6% — according to a report by IQVIA, a health care analytics company. In 2019, biologics accounted for 43% of drug spending in the U.S.

Biosimilars provide a roughly 30% discount over brand biologics in the U.S. but have the potential to reduce spending by more than $100 billion in the next five years, the IQVIA analysis found.

In a survey of 602 physicians who prescribe biologic medications, more than three-quarters said they believed biosimilars are just as safe and effective as their biologic counterparts, according to NORC.

But they were less comfortable with switching patients from a brand biologic to a biosimilar. While about half said they were very likely to prescribe a biosimilar to a patient just starting biologic therapy, only 31% said they were very likely to prescribe a biosimilar to a patient already doing well on a brand biologic.

It can be challenging to find a treatment regimen that works for patients with complicated chronic conditions, and physicians and patients often don’t want to rock the boat once that is achieved.

In Moxley’s case, for example, before her condition stabilized on Remicade, she tried a conventional pill called Lialda, the biologic drug Humira and a lower dose of Remicade.

Some doctors and patients raise concerns that switching between these drugs might cause patients to develop antibodies that cause the drugs to lose effectiveness. They want to see more research about the effects of such switches.

“We haven’t seen enough studies about patients going from the biologic to the biosimilar and bouncing back and forth,” said Dr. Marcus Snow, chair of the American College of Rheumatology’s Committee on Rheumatologic Care. “We don’t want our patients to be guinea pigs.”

Manufacturers of biologic and biosimilar drugs have participated in advertising, exhibit or sponsorship opportunities with the American College of Rheumatology, according to ACR spokesperson Jocelyn Givens.

But studies show a one-time switch from Remicade to a biosimilar like Inflectra does not cause side effects or the development of antibodies, said Dr. Ross Maltz, a pediatric gastroenterologist at Nationwide Children’s Hospital in Columbus, Ohio, and former member of the Crohn’s & Colitis Foundation’s National Scientific Advisory Committee. Studies may be conducted by researchers with extensive ties to the industry and funded by drugmakers.

Situations like Moxley’s are unusual, said Kristine Grow, senior vice president of communications at AHIP, an insurer trade group.

“For patients who have been taking a brand-name biologic for some time, health insurance providers do not typically encourage them to switch to a biosimilar because of a formulary change, and most plans exclude these patients from any changes in cost sharing due to formulary changes,” she said.

Drugmakers can seek approval from the FDA of their biosimilar as interchangeable with a biologic drug, allowing pharmacists, subject to state law, to switch a physician’s prescription from the brand drug, as they often do with generic drugs. However, the FDA has approved only one biosimilar (Semglee, a form of insulin) as interchangeable with a biologic (Lantus).

Like Moxley, many other patients using biologics get copay assistance from drug companies, but the money often isn’t enough to cover the full cost. In her old job as a radio reporter, Moxley said, she hit the $7,000 maximum annual out-of-pocket spending limit for her plan by May.

In her new job, Moxley has an individual plan with a $4,000 maximum out-of-pocket limit, which she expects to blow past once again within months.

But she received good news recently: Her new plan will cover Remicade.

“I’m still concerned that I will have developed antibodies since my last dose,” she said. “But it feels like a step in the direction of good health again.”

Amgen Biologic Drug Approved by FDA

By Pat Anson, Editor

A new biologic drug may soon be available for rheumatoid arthritis patients and others who suffer from autoimmune diseases – if they can afford it and if the drug clears a patent challenge.

The Food and Drug Administration has approved Amgen’s Amjevita as a biosimilar to Humira for the treatment of rheumatoid arthritis (RA), psoriatic arthritis, ankylosing spondylitis, Crohn’s disease, ulcerative colitis and severe plaque psoriasis. 

“Approval of Amjevita is an exciting accomplishment as it marks a new chapter in Amgen’s story of being a leader in biotechnology. In addition, Amjevita holds the potential to offer patients with chronic inflammatory diseases an additional treatment option,” said Sean Harper, M.D., executive vice president of Research and Development at Amgen.

Amjevita is Amgen’s first approved biosimilar and the fourth to receive regulatory approval in the U.S.

“The biosimilar pathway is still a new frontier and one that we expect will enhance access to treatment for patients with serious medical conditions,” said Janet Woodcock, MD, director of the FDA’s Center for Drug Evaluation and Research.

A biosimilar is nearly identical to an already-approved biological drug and there is no clinically meaningful difference in terms of their safety, purity and potency. Unlike generic drugs, however, biosimilars are not considered interchangeable with their branded counterparts – and are not given the generic label.

Zarxio was the first biosimilar product approved by the FDA as a version of Neupogen. The second was Inflectra, a biosimilar to Remicade. Last month the FDA approved Erelzi as a biosimilar to Enbrel.

Biologic products are generally derived from a living organism and can come from many sources, including humans and animals. They help inhibit the joint damage caused by rheumatoid arthritis, a chronic disease in which the body’s own immune system attacks joint tissues, causing pain, inflammation and bone erosion.

Injectable biologic drugs often work well in controlling RA and other autoimmune diseases, but can lose their effectiveness over time. They are also notoriously expensive, with some of the newer drugs costing $20,000 annually. A study last year found that Medicare patients paid an average of $835 in out-of-pocket costs every month to obtain them.

Last year Humira generated sales of more than $8 billion for drug maker AbbVie. In anticipation of Amjevita being approved by the FDA, AbbVie filed a lawsuit against Amgen last month, alleging that Amjevita infringes on 61 of its patents for Humira.

Because of that pending court case, a spokesperson for Amgen told PNN the company would be unable to provide a launch date for Amjevita or a projected price for the drug.

The most serious side effects of Amjevita are infections and malignancies. The drug will have a "Boxed Warning" to alert healthcare providers and patients about an increased risk of serious infections leading to hospitalization or death. The warning also notes that lymphoma and other malignancies, some fatal, have been reported in children and adolescent patients treated with tumor necrosis factor blockers, including Humira (adalimumab) products.
