Many Covid Patients Can’t Afford Paxlovid

By Arthur Allen, KFF Health News

Evangelical minister Eddie Hyatt believes in the healing power of prayer but “also the medical approach.” So on a February evening a week before scheduled prostate surgery, he had his sore throat checked out at an emergency room near his home in Grapevine, Texas.

A doctor confirmed that Hyatt had covid-19 and sent him to CVS with a prescription for the antiviral drug Paxlovid, the generally recommended medicine to fight covid. Hyatt handed the pharmacist the script, but then, he said, “She kept avoiding me.”

She finally looked up from her computer and said, “It’s $1,600.”

The generally healthy 76-year-old went out to the car to consult his wife about their credit card limits. “I don’t think I’ve ever spent more than $20 on a prescription,” the astonished Hyatt recalled.

That kind of sticker shock has stunned thousands of sick Americans since late December, as Pfizer shifted to commercial sales of Paxlovid. Before then, the federal government covered the cost of the drug.

The price is one reason Paxlovid is not reaching those who need it most. And patients who qualify for free doses, which Pfizer offers under an agreement with the federal government, often don’t realize it or know how to get them.

“If you want to create a barrier to people getting a treatment, making it cost a lot is the way to do it,” said William Schaffner, a professor at Vanderbilt University School of Medicine and spokesperson for the National Foundation for Infectious Diseases.

Public and medical awareness of Paxlovid’s benefits is low, and putting people through an application process to get the drug when they’re sick is a non-starter, Schaffner said. Pfizer says it takes only five minutes online.

It’s not an easy drug to use. Doctors are wary about prescribing it because of dangerous interactions with common drugs that treat cholesterol, blood clots, and other conditions. It must be taken within five days of the first symptoms. It leaves a foul taste in the mouth. In one study, 1 in 5 patients reported “rebound” covid symptoms a few days after finishing the medicine — though rebound can also occur without Paxlovid.

A recent JAMA Network study found that sick people 85 and older were less likely than younger Medicare patients to get covid therapies like Paxlovid. The drug might have prevented up to 27,000 deaths in 2022 if it had been allocated based on which patients were at highest risk from covid. Nursing home patients, who account for around 1 in 6 U.S. covid deaths, were about two-thirds as likely as other older adults to get the drug.

Vaccine Misinformation

Shrunken confidence in government health programs is one reason the drug isn’t reaching those who need it. In senior living facilities, “a lack of clear information and misinformation” are “causing residents and their families to be reluctant to take the necessary steps to reduce covid risks,” said David Gifford, chief medical officer for an association representing 14,000 health care providers, many in senior care.

The anti-vaxxers spreading falsehoods about vaccines have targeted Paxlovid as well. Some call themselves anti-paxxers.

“Proactive and health-literate people get the drug. Those who are receiving information more passively have no idea whether it’s important or harmful,” said Michael Barnett, a primary care physician at Brigham and Women’s Hospital and an associate professor at Harvard, who led the JAMA Network study.

In fact, the drug is still free for those who are uninsured or enrolled in Medicare, Medicaid, or other federal health programs, including those for veterans.

That’s what rescued Hyatt, whose Department of Veterans Affairs health plan doesn’t normally cover outpatient drugs. While he searched on his phone for a solution, the pharmacist’s assistant suddenly appeared from the store. “It won’t cost you anything!” she said.

As Hyatt’s case suggests, it helps to know to ask for free Paxlovid, although federal officials say they’ve educated clinicians and pharmacists — like the one who helped Hyatt — about the program.

“There is still a heaven!” Hyatt replied. After he had been on Paxlovid for a few days his symptoms were gone and his surgery was rescheduled.

About That $1,390 List Price

Pfizer sold the U.S. government 23.7 million five-day courses of Paxlovid, produced under an FDA emergency authorization, in 2021 and 2022, at a price of around $530 each.

Under the new agreement, Pfizer commits to provide the drug for the beneficiaries of the government insurance programs. Meanwhile, Pfizer bills insurers for some portion of the $1,390 list price. Some patients say pharmacies have quoted them prices of $1,600 or more.

How exactly Pfizer arrived at that price isn’t clear. Pfizer won’t say. A Harvard study last year estimated the cost of producing generic Paxlovid at about $15 per treatment course, including manufacturing expenses, a 10% profit markup, and 27% in taxes.

Pfizer reported $12.5 billion in Paxlovid and covid vaccine sales in 2023, after a $57 billion peak in 2022. The company’s 2024 Super Bowl ad, which cost an estimated $14 million to place, focused on Pfizer’s cancer drug pipeline, newly reinforced with its $43 billion purchase of biotech company Seagen. Unlike some other recent oft-aired Pfizer ads (“If it’s covid, Paxlovid”), it didn’t mention covid products.

The other problem is getting the drug where it is needed. “We negotiated really hard with Pfizer to make sure that Paxlovid would be available to Americans the way they were accustomed to,” Department of Health and Human Services Secretary Xavier Becerra told reporters in February. “If you have private insurance, it should not cost you much money, certainly not more than $100.”

‘This Is a Mistake’

Yet in nursing homes, getting Paxlovid is particularly cumbersome, said Chad Worz, CEO of the American Society of Consultant Pharmacists, specialists who provide medicines to care homes.

If someone in long-term care tests positive for covid, the nurse tells the physician, who orders the drug from a pharmacist, who may report back that the patient is on several drugs that interact with Paxlovid, Worz said. Figuring out which drugs to stop temporarily requires further consultations while the time for efficacious use of Paxlovid dwindles, he said.

His group tried to get the FDA to approve a shortcut similar to the standing orders that enable pharmacists to deliver anti-influenza medications when there are flu outbreaks in nursing homes, Worz said. “We were close,” he said, but “it just never came to fruition.”

“The FDA is unable to comment,” spokesperson Chanapa Tantibanchachai said.

Los Angeles County requires nursing homes to offer any covid-positive patient an antiviral, but the Centers for Medicare & Medicaid Services, which oversees nursing homes nationwide, has not issued similar guidance.

“And this is a mistake,” said Karl Steinberg, chief medical officer for two nursing home chains with facilities in San Diego County, which also has no such mandate. A requirement would ensure the patient “isn’t going to fall through the cracks,” he said.

While it hasn’t ordered doctors to prescribe Paxlovid, CMS on Jan. 4 issued detailed instructions to health insurers urging swift approval of Paxlovid prescriptions, given the five-day window for the drug’s efficacy. It also “encourages” plans to make sure pharmacists know about the free Paxlovid arrangement.

Current covid strains appear less virulent than those that circulated earlier in the pandemic, and years of vaccination and covid infection have left fewer people at risk of grave outcomes. But risk remains, particularly among older seniors, who account for most covid deaths, which number more than 13,500 so far this year in the U.S.

Steinberg, who sees patients in 15 residences, said he orders Paxlovid even for covid-positive patients without symptoms. None of the 30 to 40 patients whom he prescribed the drug in the past year needed hospitalization, he said; two stopped taking it because of nausea or the foul taste, a pertinent concern in older people whose appetites already have ebbed.

Steinberg said he knew of two patients who died of covid in his companies’ facilities this year. Neither was on Paxlovid. He can’t be sure the drug would have made a difference, but he’s not taking any chances. The benefits, he said, outweigh the risks.

Evidence Should Be Updated for Covid-19 Treatment

By Dr. Lynora Saxinger, Undark Magazine

Strong science, particularly vaccine development, helped us steer our way through the Covid-19 pandemic. Now, as the pandemic recedes, it’s time to hold drug companies accountable for the treatments they’ve developed.

The evidence for these medications has not kept pace with major changes in the nature of the Covid-19 pandemic, and updated studies should be required to maintain approval for these very profitable drugs.

The Covid-19 drug development battlefield is littered with 479 failed or inactive drugs, while 358 are still in clinical or preclinical trials, according to a tracker maintained by the Biotechnology Innovation Organization, a trade group.

The only oral Covid-19 therapy approved by the U.S. Food and Drug Administration that is recommended for first line outpatient use is Pfizer’s Paxlovid (nirmatrelvir-ritonavir), a two-drug combination that stops the SARS-CoV-2 virus from replicating in the body.

Hailed as a game changer, Paxlovid is a very good antiviral drug that has saved many lives, and its incredibly rapid development was a feat of science.

The major study leading to its approval, called the EPIC-HR trial, showed that it reduced the risk of hospitalization and death by an impressive 89 percent in high-risk, unvaccinated people.

But there is a lack of high-quality research on how Paxlovid affects outcomes beyond severe Covid — such as duration of illness, how the drug affects transmission, and whether it prevents long Covid. Nevertheless, some physicians are promoting the drug for these uses based on weak, inconsistent data.

The stakes are high: If we fail to set a requirement for well-designed studies of Paxlovid’s impact on all concerns besides hospitalization and death, we will be setting up a slow-moving, disastrous recreation of mistakes made with drugs for other diseases such as influenza.

Early in the Covid-19 pandemic, the explosive, unorganized growth of clinical trials for treatments was intended to save lives from this fearsome new disease. But many trials were small and of low quality, with a few exceptional trials providing much of our good data. In that initial desperate push for Covid-19 treatments, experimental, everything-but-the-kitchen-sink approaches became widely used.

Ivermectin Controversy

The case of ivermectin is instructive: This antiparasitic drug was used in tremendous volumes based on poor quality and sometimes outright fraudulent data, despite advice against its use from the FDA and in formal treatment guidelines. Social media amplification of the increasingly dubious evidence base led to a near-delusional belief in its benefit — and impressive profits for some opportunistic doctors.

A few well-coordinated and well-designed trials up front would have shortened the controversy, saved costs, and avoided duplicated effort of smaller low-quality trials. Most importantly, showing it to be ineffective earlier may have prevented the ensuing social media crusade, perhaps allowing some high-risk people to accept evidence-supported treatments like Paxlovid and the intravenous antiviral remdesivir rather than requesting, or even suing hospitals, to administer ivermectin.

Covid-19’s infection outcomes changed unusually rapidly across waves of the pandemic, which meant that studies could be outdated in months if they did not reflect the current viral strains and population immune responses. Data collection in the EPIC-HR study, which still guides treatment with Paxlovid, took place in 2021 when hospitalization rates were high, many were unvaccinated (including all trial participants), the viral strains were different than today, and the main outcome of interest in many communities was “flattening the curve,” or preventing hospitalization.

Now, almost everyone has been vaccinated, infected, or both. In a recent study, 96.4 percent of U.S. blood donors had Covid-19 antibodies by September 2022. The overall risk of hospitalization and death has also decreased significantly.

A Different Disease

Essentially, we are now dealing with a different disease. We are more focused on outcomes such as time lost from work, transmission risk, and long Covid risk. Yet there is almost no direct evidence about Paxlovid’s effect on these outcomes.

Paxlovid was approved for the treatment of mild to moderate Covid-19 in adults at high risk of developing severe disease. However, physicians and pharmacists have told me, it is increasingly being prescribed off-label for lower risk patients. This contention is supported by a recent U.S.-based preprint showing that 42 percent of more than 111,000 Paxlovid recipients had no major medical comorbidities, with treatment eligibility defined by having at least one risk factor for severe Covid-19.

Some physicians are extrapolating from hamster studies and lab data to suggest it reduces Covid-19 transmission. And they’re prescribing it to reduce long Covid risk based on very weak studies that analyzed administrative databases for Covid-19 complications rather than tracking long Covid symptoms in treated and untreated patients.

This matters because Paxlovid treatment for people who are not high risk has not shown significant benefit. One still unpublished randomized trial of lower-risk patients was terminated because low rates of hospitalization overall (in treated and untreated people) made it impossible to see a benefit.

Even in higher-risk groups, a recent meta-analysis of observational studies has shown very little absolute reduction of mortality, and no benefit in such patients under age 60. At the same time, people taking Paxlovid face possible side effects, drug interactions, and volatile drug pricing. They do not know if Paxlovid is worth all of that. They don’t know if the drug will reduce transmission to others, if they are less likely to get severely ill, if they will need time off work, or if it will spare them from long Covid.

Tamiflu Questions

Infectious diseases specialists like myself are experiencing an alarming sense of déjà vu. Tamiflu (oseltamivir), a treatment for influenza, was licensed in 1999 with data showing a modest benefit in reducing illness by one day. The reviewers noted that a “more definitive demonstration of clinical or public health relevance” would require additional data.

But 24 years later, we are not farther ahead — important questions about Tamiflu remain unanswered, with longstanding debates about the benefit of the drug and a false advertising lawsuit that went on for nearly 10 years before being dropped in July. The guidelines for the use of Tamiflu in influenza vary tremendously because of varied interpretation of a poor evidence base, and newer studies call its use as an influenza treatment into question. Even so, in its first 15 years on the market, Tamiflu made $18 billion in sales.

It is hard to stop a prescribing practice once it has become the norm, despite inadequate data. This is a recognized driver of cost increases in health care.

Pharmaceutical companies play a pivotal role in the research and development of effective therapies, and their lifesaving contributions during the Covid-19 pandemic have been commendable. However, the major investments these companies make in R&D should not give them free rein to market high-cost, high-volume drugs of public health importance without continued scrutiny of their effectiveness if the initial registration studies no longer stand because of changes in the disease.

Some bold, novel options could help address this gap in evidence. In exceptional circumstances (such as pandemics), pharmaceutical companies could be required to conduct studies to reassess a drug’s effectiveness after it has entered the market if conditions have meaningfully changed since the initial trials.

Another option could require companies to put a small portion of drug profits towards funding well-designed, independent trials so that crucial, commercially successful drugs would be part of ongoing studies. The FDA and other agencies should judiciously require and support such studies that could help guide treatment decisions, while balancing the need to support appropriate research and new drug development.

The medical community has responsibility, too: Professional societies that draft treatment guidelines must take a more consistently assertive stance in advising against uses for which there is insufficient evidence, rather than leaving it open to prescriber judgment. Both prescribers and potential patients need to accept and use evidence to help sustain health care systems, and lobby for changes needed to define the best treatments for people with Covid-19.

We are at a unique juncture in the fight against Covid-19, as fear gives way to complacency — and the path forward is scientific rigor. Failing to mandate high-quality evidence for treatment choices may lead us back down the path of inadequately researched treatments, opinion-driven guidelines, and wasted resources.

Pfizer has raked in about $20 billion dollars in revenue from Paxlovid alone over the last two years. This sum is nearly half of the National Institutes of Health’s entire budget for 2022. It is not surprising that the company has not voluntarily started additional trials after approval based on the stellar results in that first, now-irrelevant trial.

In the wake of the pandemic, we have an opportunity to improve both what we are doing, and how we may address research challenges in a future crisis. Paxlovid’s price is set to increase — from $530 to $1,390 before insurance — next year, but there is no corresponding increase in our knowledge of its value. The cost of this information gap will be very high, for both individuals and health care systems.

Can Antivirals Prevent Long Covid?

By The Conversation

Evidence is continuing to accumulate on the burden and frequency of chronic effects after a COVID infection, which fall under the umbrella term “long COVID”.

At least 5%–10% of people who contract COVID experience long COVID. This can include symptoms (for example, fatigue, brain fog and breathlessness) or conditions (for example, heart conditions, neurological conditions and diabetes) after the initial infection that may be persisting, new or relapsing.

Studies show the symptoms and increased risk of chronic conditions can persist for up to two years after infection. The individual impact of long COVID can range from temporary to severely disabling, and the societal cost – for example due to reduced workforce and increased health-care costs – is enormous

The lower risk of developing long COVID with up-to-date COVID vaccinations is substantially offset by the high levels of infections and re-infections globally. As a result, the cumulative burden of long COVID has increased, including in lower and middle income countries. A conservative estimate suggests 65 million people may be currently affected globally.

So where are we at with reducing the risk of, and treating, long COVID?

Reduced Risk of Severe Disease

COVID antiviral drugs, taken orally, continue to play an important role in reducing acute severe disease after infection. In Australia and the US, they’re available to those at highest risk from COVID.

Observational research has suggested taking antivirals during a COVID infection can reduce the risk of long COVID in people with at least one risk factor for acute severe COVID.

In one study, nirmatrelvir and ritonavir, known as Paxlovid, was associated with a 26% reduced risk of developing long COVID. It was also linked to a 47% reduced risk of death and a 24% reduced risk of hospitalisation after the acute infection phase.

A similar 14% reduction in long COVID risk has been reported for molnupiravir (Lagevrio).

Ensitrelvir – a COVID antiviral available in Japan – could also reduce the risk of long COVID, preliminary analyses suggest.

More research is needed, but this data indicates antiviral medications may be a key approach to lessening the risk of long COVID.

The population most at risk of long COVID (often working-age adults) differs from those most at risk of severe disease from a COVID infection (older adults or those with chronic medical conditions). Eligibility criteria to access antivirals do not currently include consideration of long COVID.

Meanwhile, one randomised trial found metformin, a commonly prescribed diabetes medication, could also reduce long COVID risk. The study offered people with symptomatic COVID who were overweight or obese metformin for two weeks (beginning within a week of symptoms starting). This group was 41% less likely to develop long COVID compared with a placebo group that didn’t take metformin.

The way this works might involve an effect on the powerhouses of our cells, mitochondria, or directly on the virus. Whatever the precise mechanism, further research should be priortised to fast-track this potential.

Still No Treatments for Long Covid

There are no effective or approved treatments for long COVID at present. Currently about 12 clinical trials are testing potential drugs. A number of candidate treatments exist for certain components of long COVID that may be useful in subgroups of patients.

However, recently we’ve seen major advances in understanding what’s actually driving long COVID in the body. This knowledge opens up approaches for both diagnosis and treatments or interventions.

An Australian parliamentary inquiry into long COVID stressed the best way to avoid the condition is to lower the risk of getting infected with COVID in the first place (through protective behaviours such as vaccination, mask wearing and cleaner indoor air).

While these are all important measures, we would benefit from having more tools at our disposal to prevent and treat long COVID. After all, COVID is still evolving rapidly and vast numbers of people are likely to be reinfected in the months and years ahead.

Overall, the quantity and speed of clinical trials into long COVID treatments has been insufficient. And most public health policy approaches are focused on preventing severe disease from a COVID infection, rather than the long-term effects.

That said, Australia recently announced an initial A$22 million of funding and a plan for research into long COVID through the Medical Research Future Fund.

In July 2023, the White House established the Office of Long COVID Research and Practice which will coordinate the US government’s response to long COVID, as well as two randomised trials of Paxlovid.

Given what we now know about long COVID, and the additional concern of what we don’t know (for example, could organ damage reveal itself many years down the track?), we desperately need diagnostic tools, clinical care pathways coupled with health worker training, and treatments to prevent and cure long COVID.

Unaddressed, long COVID may well lead to a new and substantial health and societal burden for many years to come. The response must involve prioritisation of research, such as that which led to the fast development of COVID vaccines and antivirals.

While there are some positive signs in the policy and research space, we need to see stronger recognition of long COVID and a greater sense of urgency around finding solutions.
