Why 14,000 people volunteered to be infected with the virus

Imagine being told to inhale a nasal spray full of coronavirus. More than 14,000 people in the United States and elsewhere offer their names for this purpose.

They volunteer for what is called a “human challenge trial”, an ethically controversial way to test vaccines that purposely infect people with a virus that has killed more than 270,000 people worldwide and has failed no remedy.

“It is not everyday that we give a healthy individual exposure to a pathogen – the same thing that doctors try to protect,” said Dr. Nir Eyal, director of the Center for Population-Level Bioethics from Rutgers University. “But it is becoming more and more clear [that] the only lasting way out of the current health and societal crisis is a vaccine, and there are ways to conduct such a trial that are perfectly ethical. “

A vaccine is the company’s return to normalcy – at crowded sports stadiums, birthday parties and visits to elderly loved ones, as well as some of the more than 33 million lost jobs. But a solution is probably still in a year to 18 months at best, triggering warnings of social distancing until 2022 and a second, worse wave this winter.

The problem is that vaccines take time to develop and be tested – often over a decade. The final phase of the vaccination test usually requires monitoring up to tens of thousands of people to see who is infected in their daily lives, sometimes over several years.

But leading epidemiologists, philosophers and vaccinologists have recently called for studies of human challenges to speed up the process. With careful design and informed consent, Eyal and his co-authors predict that he could deliver a vaccine months earlier and save thousands of lives.

There are no public plans for such a study in the United States, but politicians and volunteers are requesting it. More than 14,000 volunteer study participants organized an advocacy group, and 35 members of Congress recently asked regulators to consider human provocation tests. Across the Atlantic, London-based hVIVO and Switzerland-based SGS are working to launch studies on the challenges, and WHO recently published a working document outlining the criteria for an ethically acceptable design.

The Food and Drug Administration has never authorized a human provocation test for such a new disease without treatment, but it does not rule out one.

“I really think it will continue,” said Dr. Matthew Memoli, director of the Clinical Studies Unit at the National Institute of Health’s Laboratory of Infectious Diseases. “So much could change, but I think it’s likely we might see one at some point in the future. “

SHOW CAPTION

But not everyone is happy with the momentum. The concept of studies on human challenges will forever be marred by non-consensual experiences with captive or disabled populations, including research on Nazi concentration camps. Although the version of the coronavirus is consensual, it would present new risks and unknowns. There is little consensus on treatment, death rate or long-term effects – even less exactly who and how it kills.

Much of the final decision would rest with the FDA. So far, three US companies – Pfizer, Inovio and Moderna – have reached at least the first phase of clinical trials, and the FDA has not said whether studies on human challenges have yet been offered as part of declarations. at NBC News. But more than half a dozen experts tell NBC News that they expect these proposals to come.

“Challenging trials can end up pushing the limits of reasonable research risk,” said Dr. David Magnus, director of the Stanford Center for Biomedical Ethics. “I don’t know how far it will go until people say no. “

What to expect when waiting for a vaccine trial

In London, infectious disease expert Adrian Wildfire – known to his colleagues as the “flying virologist” for the motorcycle between various pathogen projects in the city – is developing plans to make coronaviruses.

It targets a Goldilocks virus – not too strong, but not too weak to infect most volunteers. He would have to rely on an outside laboratory to do this, possibly a multi-million dollar biosafety business 3, like rabies and avian flu. He would start testing the dosage on ferrets or golden hamsters, then move on to humans.

“I don’t want to make anyone deeply sick,” said Wildfire. “God forbid anyone to die trying to eliminate the virus. “

Wildfire heads the “Infectious Diseases and Human Challenges Unit” of SGS, a multinational testing company valued at nearly $ 20 billion, that conducts studies in a variety of sectors, from cybersecurity to agriculture. They’ve done studies on the challenges of flu and malaria, and Wildfire is currently working on a proposal for COVID-19.

“If we don’t do something now, and if it comes back in December, we will regret the day we didn’t start,” said Wildfire. “I think there is a certain imperative right now. “

Last week, about a dozen vaccine developers attended an SGS webinar on the COVID-19 challenge study considerations. Some left with their “panties in a twist,” said Wildfire, but most were intrigued. The London-based hVIVO laboratory is also pursuing a human challenge for a milder coronavirus strain; they would have obtained more than 20,000 volunteers in just a few days. The two studies are still being planned.

No company has publicly implemented a COVID-19 human challenge proposal in the United States, although it has increased in the past decade for diseases like cholera, flu and malaria. The ethical framework for what is happening comes in large part from a 2001 article by NIH experts that emphasizes “minimal risk”, an area where COVID-19 pushes the envelope.

“When I think of a model of human challenge, I think:” Can I get this information any other way? “,” Said Dr. Beth Kirkpatrick, chair of microbiology and molecular genetics at the University of Vermont and head of its vaccine testing center. “If you can find another way to do it, often we don’t even do it that way. “

Eyal, along with leading epidemiologists Marc Lipsitch and Peter Smith, tries to outline a roadmap for an ethical study plan. About 100 people at low risk could receive the lowest possible dose of COVID-19, their article explains. The participants would be isolated and the symptomatic volunteers could receive the best treatment available, in priority for scarce resources.

“This could, if done in the right way, not only minimize the risks, but keep them below the risks of kidney donation,” said Eyal.

The FDA is open to the idea, with reservations.

“Human challenge studies are one way to accelerate the development of a vaccine to prevent COVID-19,” the FDA wrote in a statement to NBC News. “Because these studies involve exposing volunteers to the virus, the studies raise a variety of potential scientific, feasibility and ethical issues. The FDA will work with those interested in conducting human provocation tests to help them assess these problems. “

The FDA has stated that the development of safe and effective vaccines will need to be “carefully designed and executed quickly” and that formal determinations on human challenge trials will be made on a case-by-case basis.

“A challenge study captures the imagination,” said Dr. Seema Shah, bioethicist at Lurie Children’s Hospital in Chicago, who co-authored an article on the considerations of the COVID-19 challenge study and recently joined the WHO working group on the subject. “But they have to work in a larger research ecosystem, and we cannot place all of our hopes on them. “

Shah chaired an NIH committee to assess the advisability of authorizing studies on the human challenge of the Zika virus. The committee decided against; unanswered questions about transmission and long-term effects made it too risky.

Memoli, a pioneer of human flu challenges at the NIH, says discussions are ongoing about the agency’s provocation tests. But his list of concerns is long. How could researchers siphon enough PPE and hospital space? What happens if a participant wishes to withdraw from isolation early? How can volunteers really be informed of their health risks when scientists themselves are unsure?

Memoli has infected more than 500 people with the flu. He knows what it is like to sit in a hospital with sick volunteers and does not take responsibility lightly.

“I’m not here to improve them,” said Memoli. “I’m here for the good of society and the world to generate data that can improve everyone in the long term. I have to put myself in a different mode, from a brain point of view, to do this. I have to go from a doctor to a scientist. “

He doesn’t yet know if a coronavirus challenge study is the right decision, especially since new reports show children hospitalized for heart and blood complications and patients in their 30s who have had a stroke.

Yet he too is beginning to sketch a challenge virus.

‘Are we already there?’

At the end of March, 34-year-old Josh Morrison was quarantined alone in his Brooklyn apartment when a friend emailed him about the article by Eyal, Lipsitch and Smith.

Morrison, who works as a kidney donor advocate, had hope for the first time in weeks. He created a group called 1DaySooner to organize volunteers. It has received more than 14,000 registrations in 102 countries.

“The expected value is even to have a vaccine a day faster,” said Morrison. “We want people to see that there are enthusiastic people about it. “

Volunteers are mothers, students, veterans, historians, journalists, doctors and about 20 healthy years. “I am older, 52, my children have grown up and I feel that if I can help save people who are not in the same situation, I should do it,” wrote one. ‘them. Another volunteer, who lost half a leg after a head-on collision with a trailer, wrote, “It would give me a chance to regain my sense of self, help and protect others, especially my daughter. one year. A volunteer has just been linked to the slogan of the First World War, “Dad, what did you do during the Great War?” “

Survey responses shared with NBC News include expressions of helplessness and a desire to save high-risk loved ones.

“No one is required to participate in a trial like this, just as no one is required to be a kidney donor,” said Morrison. “If people are ready and willing to give it a try like this, and the trial would be useful, I think it would be wrong to stop it from moving forward. “

But as enthusiasm intensifies, some experts are cautious.

“We have to keep asking the question, are we still there?” Said Dr. James Giordano, professor of neurology and biochemistry and bioethicist at Georgetown University Medical Center. “Are we at the point where a challenge trial is absolutely necessary? “

There is simply not enough data to make a final ethical calculation, six bioethics experts told NBC News.

The uncertainty is acceptable, say some volunteers. But Thomas Williams, a law and bioscience fellow at Duke University, compares him to a lifeguard diving into a riptide to save a drowning swimmer. A worse scenario could involve “a fair amount of human cost”.

“I could imagine that the pharmaceutical companies are not comfortable with the idea that they are the first to come out of the doors – impatient and thirsty for teeth,” said Williams. “There is a responsibility in terms of public perception that would come with a failed human challenge trial. “

Enter the politicians. The bipartisan letter from 35 members of the House urging regulators to consider human challenge trials was designed to give the FDA “political cover,” according to representative office William Foster, D.-Ill., Who led the initiative with representative Donna Shalala. , D.-Fla. President Donald Trump’s “Operation Warp Speed” – an effort to accelerate the development of a vaccine – could still protect vaccine developers from liability in the event of an adverse outcome, the New York Times reported.

Asked last Sunday if he was concerned about the ethics of a human challenge trial, Trump replied, “No, because they are volunteers. They know what they are getting into. They are very good people, they want to help the process. . “

The pandemic has already altered the risk appetite of regulators. The FDA has issued over 100 emergency use authorizations related to coronaviruses, authorizing the marketing of unapproved medical products. Moderna, one of the precursors to the vaccine, has been allowed to proceed to human clinical trials before testing its product on animals.

At SGS, Wildfire sees a human provocation test more as a mental health check than an accelerated procedure: a way to find the most effective candidate vaccine for a larger study. Morrison has a simpler view; at current infection rates, if a vaccine saves 0.5% of people, a solution a day earlier could save 19,500 lives. So, for him, a trial of human challenge is a gamble.

“We all want to do more than hope,” said Morrison. “We are looking for a way to help, if we can. “
