Learning from COVID Drug Development

On December 11, 2020 the FDA issued an emergency use authorization (EUA) for the Pfizer-BioNTech COVID-19 Vaccine. Then on December 18th, the FDA issued an EUA for the Moderna COVID-19 Vaccine. The FDA News Releases for both drugs said the data provided clear evidence both vaccines may be effective in preventing COVID-19. The known and potential benefits for both drugs were said to outweigh the known and potential risks. “In making this determination, the FDA can assure the public and medical community that it has conducted a thorough evaluation of the available safety, effectiveness and manufacturing quality information.”

In December of 2019, no one knew COVID-19 existed and now there are two vaccines being distributed in the US that are both around 95% effective in preventing the novel coronavirus. Despite the unprecedented speed of their development, there were not any compromises with the safety or the scientific integrity of the process. According to Dr. Anthony Fauci, the speed was “a reflection of the extraordinary scientific advances in these types of vaccines which allowed us to do things in months that actually took years before.” He wanted to settle the concerns some people have about the rush of development and approval. Despite the politicization of the process, there was an independent body of people with no allegiance to the administration or to the pharmaceutical companies who were the first ones to review and then approve the data from the companies’ late-stage clinical trials. “We need to put to rest any concept that this was rushed in an inappropriate way . . . Help is on the way.”

The FDA requires that a vaccine be at least 50% effective, according to the latest guidance. By comparison, two doses of the measles vaccine is about 97% effective, and flu vaccines range from about 40% to 60% effective, according to the Centers for Disease Control and Prevention (CDC).

The FDA just finalized the guidance for EUAs in January of 2017. The purpose of this guidance was to explain the FDA’s current thinking on the authorization of the emergency use of certain medical products under certain sections of the Federal Food, Drug and Cosmetic Act, as it was amended or added to by the Pandemic Reauthorization Act of 2013 (PAHPRA).

The provisions in PAHPRA include key legal authorities to sustain and strengthen national preparedness for public health, military, and domestic emergencies involving chemical, biological, radiological, and nuclear (CBRN) agents, including emerging infectious disease threats.

The Washington Post published an article that addressed common concerns about the COVID-19 vaccines. First, it is not just the vulnerable who should get the vaccine. Vaccines protect more than just the person who is inoculated. The more people who are vaccinated means there are fewer people the virus can infect, “lowering the infection rate and the risk for us all.” Another reason is to protect those who cannot get it. The first two approved vaccines were only approved for individuals over the ages of sixteen for the Pfizer-BioNTech COVID-19 Vaccine and 18 for the Moderna COVID-19 Vaccine.

Your decision not to get vaccinated could affect other people around you. Individuals with a weakened immune system may need to rely on the immunity of others to keep them healthy. Not getting a vaccine would be like refusing to wear a mask. We will likely have to wear masks through 2021. In fact, vaccinated people should wear masks and follow social distance guidelines. While the vaccine is effective at reducing symptomatic illness, it is not yet known whether it reduces the likelihood of contracting the coronavirus and being an asymptomatic carrier.

As more people get vaccinated and the US gets to community or herd immunity, there will come a point when we can do away with the masks. “In the meantime, vaccination is a crucial tool. It doesn’t replace other tools but is a powerful measure that can help save lives and help the economy recover.” Allergic reactions can be treated without lasting consequences, but the same is not true for COVID-19. At this time, it is not known what component of the vaccine triggers allergic reactions, but there is not reason for people with food or medication allergies to avoid the vaccine as long as they are monitored in a health-care setting.

All viruses mutate and it may turn out that people will have to receive regular booster shots, like with tetanus or the flu shot. Enough mutations could eventually reduce the potency of existing vaccines. A study of the Moderna vaccine found it was effective for at least 119 days. But some experts believe immunity should last at least a year. “The theoretical necessity of future vaccinations doesn’t override the urgency of getting one now.”

For those worried about political interference in expediting approval, it’s critical to emphasize that no shortcuts were taken in research or the approval process. Vaccine safety was tested in phase 3 trials involving tens of thousands of participants. External committees of scientists vetted the data and produced independent recommendations to support vaccine authorization.

The Allegheny Health Network (AHN) posted a series of frequently asked questions (FAQs) and answers that addressed further questions about the COVID-19 vaccines. The further information there included that no doctor’s order will be necessary to get the vaccine, but you will have to schedule an appointment. AHN said the vaccine is free to all Americans and will be available at retail pharmacies. “Remember, some vaccines require two doses to be effective. It’s extremely important you get both and follow the suggested timeline.”

Who knows where we’ll be with COVID in another twelve months! But there are some things we’ve learned through this pandemic about drug companies and hopefully will continue to insist on. Drug development can be done quickly and safely. Pharmaceutical companies can be open and transparent about their research and allow truly independent, external committees to verify their findings. People can trust the results of drug development when the clinical trial process is not statistically or methodologically manipulated to show what the researchers want to find.

The widespread mistrust of science that became evident during the pandemic seems partly due to the previous manipulation of drug development by the pharmaceutical companies. Like good illusionists, they directed our attention to what they wanted us to see and away from what they wanted to hide. Going forward, open, transparent drug development can restore the trust that is now lacking for the COVID vaccine. During the pandemic drug companies showed they could do COVID Drug Development quickly and safely. We need to remember these things and hold the drug companies accountable to these standards.

Runaway Pharma Gravy Train

The Pharmaceutical Research and Manufacturers of America (PhRMA) spent $27.5 million on lobbying in Washington last year. This was a new record, surpassing the previous high set in 2009, when PhRMA spent over $27 million. “The new record also topped 2017’s lobbying spend—$25.43 million, at a time when Trump was taking office and pricing was often on the airwaves—by about 8%.” The increases parallel steadily increasing prices for several years. For example, Medicaid drug costs nearly doubled to $31 billion.

Rep. Elijah Cummings initiated an investigation of 12 pharmaceutical companies in an effort to uncover pharma pricing practices. Cummings sent letters seeking information and documents about the companies’ pricing practices. This is the first step of the Committee on Oversight and Reform’s review of pricing practices. The Committee will also hold hearings in order to hear from experts and patients affected by rising drug prices.

The Centers for Medicare and Medicaid Services projects that spending on prescription drugs will increase more rapidly than spending on any other health care sector over the next ten years.  The federal government bears much of the financial burden of escalating drug prices through Medicare Part D, which provides drug coverage to approximately 43 million people.  The government is projected to spend $99 billion on Medicare Part D in 2019.  In 2016, the 20 most expensive drugs to Medicare Part D accounted for roughly $37.7 billion in spending.

The hearing was held on Tuesday, January 29, 2019, just two weeks after Rep. Cummings sent out his letters. There also seems to be bipartisan support to rein in drug prices.  FiercePharma wondered whether this was real bipartisan unity or just talk. Rep. Mark Meadows, A Republican from North Carolina, said President Trump asked him to make sure the House knew on this issue, “He’s serious about working in a bipartisan way to lower prescription drug prices.” At the hearing Cummings acknowledged Trumps support, but said: “But tweets are not enough—we need real action and meaningful reforms.”

STAT News reported that Cummings is asking for “10 years worth of sales, revenue, pricing, rebate, discount, and commercialization data.” Additionally he’s asked for information detailing research and development expenses; information on patents and indications; employee compensation and bonus details; each company’s interaction with federal agencies; and details of company’s contracts with PBMs (pharmacy benefit mangers). Although his probe already includes most of the country’s largest pharmaceutical companies, he’s not finished. “There’ll be more.” Other congressional committees, such as Energy and Commerce and the Senate Finance Committee, are planning to do their own investigations.

The ten most expensive brand-name drugs accounted for $15.6 billion of spending in the catastrophic coverage phase of the Medicare Part D benefit in 2015. While the number of prescriptions fell by 17%, the Part D payments for brand-name drugs increased by 62% from 2011 to 2015. The payments for about 94% of commonly used medications more than doubled. The percentage of Medicare Part D beneficiaries who paid at least $2,000 out-of-pocket for their drugs almost doubled from 2011 to 2015. Cummings is focusing his inquiries on drugs that are among the costliest to Medicare Part D. If you’re curious, there is a link in the article to a list of the companies and drugs for conditions ranging from arthritis, cancer and cholesterol to diabetes.

An NPR and Center for Public Integrity investigation found drug companies have penetrated almost all aspects of the process that determines how their drugs are covered by taxpayers. Doctors on obscure committees advising state Medicaid programs receive free dinners and consulting contracts with the pharmaceutical companies. Speakers who don’t disclose their financial ties to the pharmaceutical companies are asked to testify about the companies’ drugs. State Medicaid officials are invited to attend all-inclusive conferences for free where they mingle with drug representatives.

Beyond that, drugmakers use other tactics to get their products paid for by the Medicaid programs: lobbying state lawmakers to achieve their goals or helping doctors fill out extra paperwork to get Medicaid to pay for the costlier drugs as Warner Chilcott did. The result is that Medicaid sometimes spends more than necessary and may pay for medicines inappropriate for patients.

The drug companies say they are not responsible for the problems. A spokesperson for PhRMA said: “As an industry, our priority is ensuring that patients have access to the medicines they need . . . . States should consider changes to Medicaid that are in line with the intended goal of ensuring robust access to medically necessary drugs.” Pharmaceutical companies have strong incentives to be included on states’ lists of approved drugs. Doctors are far more likely to prescribe an approved drug to Medicaid patients and may encourage other insurers to do the same. To gain a spot on the coveted lists, drug makers offer the states “supplemental rebates,” which are on top of other price concessions required by federal law. “The drug committee meetings where those list decisions are made are a frequent destination for drug company representatives — and those who benefit from their largesse.”

Across the country, drugmaker representatives and pharma-friendly clinicians with industry ties swarm these low-profile drug committees, a review of meeting minutes shows. Center for Public Integrity and NPR reporters saw similar dynamics play out this spring in meetings in Arizona, Washington, D.C., and Louisiana. The committees, usually known as pharmacy and therapeutics committees or drug utilization review boards, are typically made up of volunteer pharmacists and doctors.

Critics of the practice say when pharma companies target these committees, the states don’t get good deals. They also can make bad decisions for their patients. Three out of five doctors voting on state Medicaid decisions received perks from pharmaceutical companies. There are at least 38 states with doctors serving on their Medicaid drug committees who collected more than $1,000 from pharmaceutical companies while they served on the committees. Consider that while this amount may point to how money influences Medicaid decisions, a study in JAMA Internal Medicine, “Pharmaceutical Industry-Sponsored Meals and Physician Prescribing Patterns for Medicare Beneficiaries” found that when doctors get as little as a $20 lunch, they are more likely to prescribe the company’s drugs.

As compared with the receipt of no industry-sponsored meals, we found that receipt of a single industry-sponsored meal, with a mean value of less than $20, was associated with prescription of the promoted brand-name drug at significantly higher rates to Medicare beneficiaries. The differences persisted after controlling for prescribing volume and potential confounders such as physician specialty, practice setting, and demographic characteristics. Furthermore, the relationship was dose dependent, with additional meals and costlier meals associated with greater increases in prescribing of the promoted drug.

The NPR article told of a nonprofit organization, the American Drug Utilization Review Society (ADURS), whose mission is to provide a forum of leadership and support for its members. It hosted a free conference for Arizona state Medicaid officials in Scottsdale, where Michael Magnotti, an endocrinologist, gave a talk on diabetes. He was paid $1,545 for the talk by Sanofi-Aventis; and he received more than $108,000 in consulting fees from pharmaceutical companies for that year.  Sanofi S.A. is the world’s fifth-largest multinational pharmaceutical company. And it was one of the companies to receive a letter from Rep. Cummings.

A more disturbing ADURS conference took place in 2003 when Purdue Pharma helped to fund it. A speaker told his audience that addiction from the medical use of opioids was rare, and he then described a phenomenon called “pseudoaddiction.” A slideshow of the presentation (linked in the STAT article) said pseudoaddiction included “appropriate drug seeking behavior” such as demanding doses before they are scheduled. In support of his claims, he referenced a letter published in the New England Medical Journal back in 1980: “Addiction Rare in Patients Treated with Narcotics.”

This article has been repeatedly misused by pharmaceutical companies (like Purdue) as they assert that the risk of addiction from the medical use of opioids is almost nil. The potential influence of pharmaceutical companies like Purdue on opioid prescribing and the opioid epidemic has received significant attention in the media. Currently 24 states and Puerto Rico have sued Purdue for downplaying or concealing the risks of its painkillers. See the book by Barry Meier, Pain Killer for more on this issue. Also see “Doublespeak in the Opioid Crisis,” Part 1 and Part 2 for more about the misuse of the 1980 article. See “Giving an Opioid Devil Its Due” for more on Purdue Pharma. This concern is now being looked at in the research literature.

A new study released on January 18, 2019 in JAMA Network Open suggested there may be a link between aggressive marketing, drug company money and overdose death rates. The researchers found that counties receiving pharmaceutical marketing of opioids to physicians subsequently experienced increased mortality rates. Commenting on the study, Science Alert said while the study did not demonstrate a cause-and-effect relationship, it did suggest that frequent trust-building visits, like lunches sponsored by drug sales reps, did more to promote prescribing the company’s drugs than high-dollar payments to physicians. One of the researchers said: “What seems to matter most wasn’t the amount of money doctors were paid, it was the number of times they were paid.”

Our findings suggest that direct-to-physician opioid marketing may counter current national efforts to reduce the number of opioids prescribedand that policymakers might consider limits on these activities as part of a robust, evidence-based response to the opioid overdose epidemic in the United States.

While Pharma’s spending on lobbying and advertising to doctors (and consumers) continues to rise, so do the negative consequences. Pharma knows marketing has a tremendous potential to grow its profits. So spending on lobbying has increased alongside that of marketing to doctors and consumers. The public pays a price by permitting these activities to continue unhindered. Unchecked greed seems to have helped facilitate the opioid crisis. Hopefully the efforts of legislators like Elijah Cummings will make it out of their respective committees and into law. We need to stop the runaway Pharma gravy train.
