Why PBMs and Payers Are Embracing Insulin Biosimilars with Higher Prices—And What That Means for Humira (rerun with an FTC update)

This week, I’m rerunning some popular posts while we put the finishing touches on DCI’s new 2024-25 Economic Report on Pharmaceutical Wholesalers and Specialty Distributors.

Last week, the Federal Trade Commission (FTC) released the redacted version of administrative complaint against the three largest pharmacy benefit managers (PBMs). The FTC rightly calls out how the gross-to-net bubble can raise patients’ out-of-pocket costs, while also acknowledging how rebates can reduce a plan's (but not the patient’s) costs. Apparently, the FTC believes that PBMs’ customers are pretty dumb, because PBMs are able to prevent plans from “appreciating” such healthcare financing dynamics.

Section V.E. of the complaint (starting on page 23) focuses on the PBMs’ alleged unlawful conduct related to preferring high-list/high-rebate insulin products over versions with lower list prices. I thought it would therefore be fun to take the Wayback Machine to November 2021, when I wrote about this specific topic.

Below, you can review my commentary about the warped incentives behind Viatris’ dual-pricing strategy for its interchangeable biosimilar of Lantus. Much of the FTC’s description of the drug channel aligns with my commentary. But before you fist pump too hard for Ms. Khan’s FTC, you should pause to reflect on the agency’s legal theories in light of plans’ revealed preferences.



The Food & Drug Administration (FDA) recently approved the first interchangeable biosimilar insulin product: the insulin glargine-yfgn injection from Viatris. Read the FDA’s press release.

Alas, I’m sad to report that the warped incentives baked into the U.S. drug channel will limit the impact of this impressive breakthrough.

Viatris is being forced to launch both a high-priced and a low-priced version of the biosimilar. However, only the high-list/high-rebate, branded version will be available on Express Scripts’ largest commercial formulary. Express Scripts will block both the branded reference product and the lower-priced, unbranded—but also interchangeable—version. Meanwhile, Prime Therapeutics will place both versions on its formularies, leaving the choice up to its plan sponsor clients.

Consequently, many commercial payers will adopt the more expensive product instead of the identical—but cheaper—version. As usual, patients will be the ultimate victims of our current drug pricing system.

Below, I explain the weird economics behind this decision, highlight the negative impact on patients, and speculate on what this all could mean for biosimilars’ future. Until plan sponsors break their addiction to rebates, today’s U.S. drug channel problems will remain.

Transparency Shocker: Biosimilars Are Getting Cheaper—But Hospitals and Insurers Can Make Them Expensive

Here on Drug Channels, we have long highlighted the boom in provider-administered biosimilars. In contrast to the pharmacy market, adoption of these biosimilars is growing, prices are dropping, and formulary barriers continue to fall.

Novel transparency information reveals that this good news doesn’t always translate into savings. Below, we rely on a unique data set from Turquoise Health to examine how much four national commercial health plans—Aetna, Anthem, Cigna, and UnitedHealthcare—paid hospitals for Avastin and its two most significant biosimilar competitors.

As we demonstrate, health plans pay hospitals far above acquisition costs for biosimilars. What’s more, plans can pay hospitals more for a biosimilar than for the higher-cost reference product. The U.S. drug channel system is warping hospitals’ incentives to adopt biosimilars, while simultaneously raising costs for commercial plans.

These Words Have (Temporarily) Relocated

Near the end of last year, I had the bright idea of starting a second blog, Placebo Lead-In, to capture a lot of smaller items that I found interesting but wasn't going to work up into a full-blown, 1000 word post.

According to Murphy’s Law, or the Law of Unintended Consequences, or the Law of Biting Off More Than You Can Chew, or some such similar iron rule of the universe, what happened next should have been predictable.

First, my team at CAHG Trials launched a new blog, First Patient In. FPI is dedicated to an open discussion of patient recruitment ideas, and I’m extremely proud of what we've published so far.

Next, I was invited to be a guest blogger for the upcoming Partnerships in Clinical Trials Conference.

Suddenly, I've gone from 1 blog to 4. And while my writing output appears to have increased, it definitely hasn't quadrupled. So this blog has been quiet for a bit too long as a result.

The good news is that the situation is temporary - Partnerships will actually happen at the end of this month. (If you’re going: drop me a line and let’s meet. If you’re not: you really should come and join us!) My contributions to FPI will settle into a monthly post, as I have a fascinating and clever team to handle most of the content.

REMOTE Redux: DTP trials are still hard

Maybe those pesky sites are good for something after all. 

It's been six years since Pfizer boldly announced the launch of its "clinical trial in a box". The REMOTE trial was designed to be entirely online, and involved no research sites: study information and consent was delivered via the web, and medications and diaries were shipped directly to patients' homes.

Despite the initial fanfare, within a month REMOTE's registration on ClinicalTrials.gov was quietly reduced from 600 to 283. The smaller trial ended not with a bang but a whimper, having randomized only 18 patients in over a year of recruiting.

Still, the allure of direct to patient clinical trials remains strong, due to a confluence of two factors. First, a frenzy of interest in running "patient centric clinical trials". Sponsors are scrambling to show they are doing something – anything – to show they have shifted to a patient-centered mindset. We cannot seem to agree what this means (as a great illustration of this, a recent article in Forbes on "How Patients Are Changing Clinical Trials" contained no specific examples of actual trials that had been changed by patients), but running a trial that directly engages patients wherever they are seems like it could work.

The less-openly-discussed other factor leading to interest in these DIY trials is sponsors' continuing willingness to heap almost all of the blame for slow-moving studies onto their research sites. If it’s all the sites’ fault – the reasoning goes – then cutting them out of the process should result in trials that are both faster and cheaper. (There are reasons to be skeptical about this, as I have discussed in the past, but the desire to drop all those pesky sites is palpable.)

However, while a few proof-of-concept studies have been done, there really doesn't seem to have been another trial to attempt a full-blown direct-to-patient clinical trial. Other pilots have been more successful, but had fairly lightweight protocols. For all its problems, REMOTE was a seriously ambitious project that attempted to package a full-blown interventional clinical trial, not an observational study.

In this context, it's great to see published results of the TAPIR Trial in vasculitis, which as far as I can tell is the first real attempt to run a DIY trial of a similar magnitude to REMOTE.

TAPIR was actually two parallel trials, identical in every respect except for their sites: one trial used a traditional group of 8 sites, while the other was virtual and recruited patients from anywhere in the country. So this was a real-time, head-to-head assessment of site performance.

And the results after a full two years of active enrollment?

  • Traditional sites: 49 enrolled
  • Patient centric: 10 enrolled
Even though we’re six years later, and online/mobile communications are even more ubiquitous, we still see the exact same struggle to enroll patients.

Maybe it’s time to stop blaming the sites? To be fair, they didn’t exactly set the world on fire – and I’m guessing the total cost of activating the 8 sites significantly exceeded the costs of setting up the virtual recruitment and patient logistics. But still, the site-less, “patient centric” approach once again came up astonishingly short.

Stretchy Wearables Can Now Heal Themselves



If you’ve ever tried to get a bandage to stick to your elbow, you understand the difficulty in creating wearable devices that attach securely to the human body. Add digital electronic circuitry, and the problem becomes more complicated. Now include the need for the device to fix breaks and damage automatically—and let’s make it biodegradable while we’re at it—and many researchers would throw up their hands in surrender.

Fortunately, an international team led by researchers at Korea University Graduate School of Converging Science and Technology (KU-KIST) persevered, and has developed conductor materials that it claims are stretchable, self-healing, and biocompatible. Their project was described this month in the journal Science Advances.

The biodegradable conductor offers a new approach to patient monitoring and delivering treatments directly to the tissues and organs where they are needed. For example, a smart patch made of these materials could measure motion, temperature, and other biological data. The material could also be used to create sensor patches that can be implanted inside the body, and even mounted on the surface of internal organs. The biocompatible materials can be designed to degrade after a period of time, eliminating the need for an invasive procedure to remove the sensor later.

“This new technology is a glimpse at the future of remote healthcare,” says Robert Rose, CEO of Rose Strategic Partners, LLC. “Remote patient monitoring is an industry still in its early stages, but already we are seeing the promise of what is not only possible, but close on the horizon. Imagine a device implanted at a surgical site to monitor and report your internal healing progress. If it is damaged, the device can heal itself, and when the job is done, it simply dissolves. It sounds like science fiction, but it’s now science fact.”

Self-healing elastics

After being cut a ribbonlike film was able to heal itself in about 1 minute.Suk-Won Hwang

The system relies on two different layers of flexible material, both self-healing: one is for conduction and the other is an elastomer layer that serves as a substrate to support the sensors and circuitry needed to collect data. The conductor layer is based on a substance known by the acronym PEDOT:PSS, which is short for Poly(3,4-ethylenedioxythiophene) polystyrene sulfonate. It’s a conductive polymer widely used in making flexible displays and touch panels, as well as wearable devices. To increase the polymer’s conductivity and self-healing properties, the research team used additives including polyethylene glycol and glycol, which helped increase conductivity as well as the material’s ability to automatically repair damage such as cuts or tears.

In order to conform to curved tissues and survive typical body motion, the substrate layer must be extremely flexible. The researchers based it on elastomers that can match the shape of curved tissues, such as skin or individual organs.

These two layers stick to each other, thanks to chemical bonds that can connect the polymer chains of the plastic films in each layer. Combined, these materials create a system that is flexible and stretchable. In testing, the researchers showed that the materials could survive stretching up to 500 percent.

The self-healing function arises from the material’s ability to reconnect to itself when cut or otherwise damaged. This self-healing feature is based on a chemical process called disulfide metathesis. In short, polymer molecules containing pairs of linked sulfur atoms, called disulfides, have the ability to reform themselves after being severed. The phenomenon arises from a chemical process called disulfide-disulfide shuffling reactions, in which disulfide bonds in the molecule break and then reform, not necessarily between the original partners. According to the KU-KIST researchers, after being cut, their material was able to recover conductivity in its circuits within about two minutes without any intervention. The material was also tested for bending, twisting, and its ability to function both in air and under water.

This approach offers many advantages over other flexible electronics designs. For example, silver nanowires and carbon nanotubes have been used as the basis for stretchable devices, but they can be brittle and lack the self-healing properties of the KU-KIST materials. Other materials such as liquid metals can self-heal, but they are typically difficult to handle and integrate into wearable circuitry.

As a demonstration, the team created a multifunction sensor that included humidity, temperature, and pressure sensors that was approximately 4.5 square centimeters. In spite of being cut in four separate locations, it was able to heal itself and continue to provide sensor readings.

Implant tested in a rat

To take the demonstration a step further, the researchers created a 1.8-cm2 device that was attached to a rat’s bladder. The device was designed to wrap around the bladder and then adhere to itself, so no adhesives or sutures were required to attach the sensor onto the bladder. The team chose the bladder for their experiments because, under normal conditions, its size can change by 300 percent.

The device incorporated both electrodes and pressure sensors, which were able to detect changes in the bladder pressure. The electrodes could detect bladder voiding, through electromyography signals, as well as stimulate the bladder to induce urination. As with the initial demonstration, intentional damage to the device’s circuitry healed on its own, without intervention.

The biocompatible and biodegradable nature of the materials is important because it means that devices fabricated with them can be worn on the skin, as well as implanted within the body. The fact that the materials are biodegradable means that implants would not need a second surgical procedure to remove them. They could be left in place after serving their purpose, and they would be absorbed by the body.

According to Suk-Won Hwang, assistant professor at KU-KIST, a few hurdles remain on the path to commercialization. “We need to test the biocompatibility of some of the materials used in the conductor and substrate layers. While scalable production appears to be feasible, the high cost of disulfide derivatives might make the technology too expensive, aside from some special applications,” he says. “Biocompatibility testing and material synthesis optimization will take one to two years, at least.”
