Clinical trials are the cornerstone of drug development. No drug can be approved without having been shown to be effective in volunteers.
But in the early months of the COVID-19 pandemic, the peak of clinical trials was derailed in closed clinics and hospitals that only had time for urgent care. Suddenly, virtual visits and home care — which once seemed — have become routine.
Meanwhile, COVID-19 trials have received the kind of endless money and public that will probably never be seen again.
The mix has taught clinical trial companies several lessons, some of which will likely last long-term. One, the need for diversity.
“If you need other people to come in for treatments, you’re better off checking for medications or vaccines in other people who look like them,” said Arthur Caplan, a medical ethicist at New York University’s Grossman School of Medicine.
Before the pandemic, trial organizers said they were aiming for diversity. “We’ve talked a lot about it, but we’ve never done so much,” said Dr. Paul Evans, CEO and president of Velocity, which conducts late-phase testing. Trials for pharmaceutical companies. ” It’s not lip service anymore. “
‘WE JUST STARTED TO KNOW WHAT IT IS’: Why doctors are suffering from COVID remedies for a long time
WHAT CAUSES THE LONG COVID AND ITS STRANGE RANGE OF SYMPTOMS?Researchers have some clues.
Today, trial organizers are doing their best to succeed in patients from diverse backgrounds and in fields that were previously overlooked. They use video chats instead of all in-person visits to make testing more convenient. And they’re reconsidering strict criteria that rule out those who don’t have unusual medical conditions and have disproportionate effects on other people of color.
Clinical trials remain the most expensive component of drug development, and the pressure for diversity drives prices up even higher, Evans said. Going beyond the same old resources takes time and effort.
It takes about 12 years to bring a drug to market, largely because of the time it takes to conduct clinical trials, said Natalie Schibell, director of research at Forrester Research, which analyzes business, marketing and generation trends.
In a typical trial, about 30% of volunteer patients drop out. Enrolling a patient costs about $6500 and replacing a patient can charge $19,500, up to $600,000 to $1 million if it’s an initial trial with few patients, Schhimell said. “All this data, all that resources in the tube. “
But health care values the extra effort and charge to continue diversifying trials, Evans said. “In fact, it means we have a larger clinical base for approving drugs and allowing them to be widely prescribed. “
The diversity of trials is key to diseases and finding effective drugs, several experts said.
Multiple blood cancer myeloma, for example, appears more in other African-Americans, but is less likely to be included in clinical trials than in other white people, said Dr. David Gerber, a medical oncologist at Harold C. Simmons Comprehensive. Cancer Center at UT Southwestern in Dallas. Scientists may not notice biological differences until more African-Americans can participate in trials, he said.
The same goes for Alzheimer. La inherited disease of a gene known as APOE4 has been linked to a particularly increased threat of Alzheimer’s disease arising. But this superior threat has been most commonly noticed in white people, said Rhoda Au, director of global cohort. progression in Davos Alzheimer’s Collaborative, which works to drive innovation in drug diagnosis and progression.
It’s possible something different was happening among black and likely Hispanic participants, he said. Even less is known about the gene in other people of Asian-American descent, as no large study has ever been done on those patients.
NOTICE: COVID-19 is still fatal real. Why do we allow incorrect information to persist?
To expand the diversity of its trial participants, the Davos Alzheimer’s Collaborative conducts clinics in 16 countries in addition to the United States.
But the push to come with trial participants from around the world is also forcing researchers to reconsider some of their classic approaches, said Au, an expert in dementia and aging at Boston University School of Medicine.
In the United States, the most complicated query in a cognitive check asks other people to look at an abacus symbol and call it. But abacuses are common in China. ” They use the same verification” in China and the US. He said, however, “it’s not the same to check. “
Despite genuine efforts to increase diversity, the trials still don’t actually reflect the entire U. S. population. “The U. S. Navy,” Caplan said.
Counting 6 percent of trial participants as “Asian” could reflect their role in the U. S. population. But he doesn’t begin to perceive social, economic or genetic differences between, say, other people of Indian, Han Chinese or Korean descent, he said. “Hispanic” has a problem.
The trials still don’t adequately reflect other people with disabilities, other trans people and, indeed, other people with disabilities, he said. Other black people in the Bronx are also likely to eat other foods, have other backgrounds, and are exposed to other contaminants, and therefore, would likely react to medications than other people in the rural South, wealthy Atlanta, or Africa. (Pregnancy is another consideration, she said, because of concerns about harming the fetus. )
Companies and the government have also begun to recognize that restrictions on clinical trials skew their results.
The lawsuits have different effects on populations, putting those already at a disadvantage, Gerber said.
For example, verification thresholds for mobile white blood cell counts are regularly set high enough to make sure patients don’t get infections too easily. But blacks have lower mobile white blood cell counts than whites, so they are less likely to succeed at thresholds. said Gerber of UT Southwestern, where 40 percent of cancer trial participants are from underrepresented minority groups.
It’s also not unusual for clinical trials to eliminate patients based on the medications they’re taking for a drug interaction. But again, blacks are more likely to take those drugs than whites, he said.
Because of strict eligibility criteria, 90% to 95% of other people who volunteer for Alzheimer’s clinical trials are eliminated, Au said.
“We’re telling the vast majority of people who want to participate to participate,” he said. “We need to say yes to everyone, but we have to give them a position to go. “
One of the other big tweaks over the past decade and the pandemic has been public awareness that clinical trials can bring benefits and be personally useful, Caplan said. Instead of worrying about being manipulated or abused, he says, patients now ask, “How come we can’t do this?
The history of clinical trials has included many abuses, especially among other people of color. Restrictions and ethics now stand in the way of many such abuses, even if many are reluctant to participate.
Evans, speaking recently on an industry panel, noted that the pandemic has provided a moment of public awareness and acceptance of trials; However, he worries that the box could let that slip away. “The general public now understands what we do and how we do it. “We’ve taken this bull by the horns and built on it and improved our relationships with the general population. “

It is usually the healthiest patients with the greatest benefits who participate in clinical trials, who can and physically manage to travel to the main medical facility where trials are conducted regularly. And they are those whose doctors are aware of the trials and inspire their patients to participate.
To inspire more people to participate in trials, the procedure must be undeniable and affordable, Mavens said.
Volunteers are allowed to receive reimbursement for participation fees — transportation, parking, lunch cash — but may not sign up if they have to go too far, said Janelle Sabo, vice president of clinical studies functions at Eli Lilly, the pharmaceutical giant.
The average American spends at least 80% of their time within 40 miles of their home. “If you can figure out how to conduct a clinical exam within that same radius, your probability of a patient participating is more than 70 percent,” Sabo said. Said. Beyond that, the figure begins to decline. “By the time at 75 miles or more, in single-digit percentages of patients who will say yes. “
Since clinical trials have been conducted at large medical centers, anyone who didn’t live nearby probably wouldn’t participate. And even for those who live nearby, “if it costs $10 to get there and they have 3 jobs, it’s not very suitable,” Sabo said.
In 2020, Bristol Myers Squibb claimed that at least 25% of its U. S. control sites were not limited to the U. S. The U. S. deserves to be close to varied populations. ” We’re at 55% right now,” said Kate Owen, the company’s senior vice president of global clinical progression. operations.
At control sites, where the company intentionally hired a diverse workforce, other people of color make up about 40 percent of participants, he said. “Having clinics there makes a difference. “
Lilly has taken time out of the pandemic to reconsider how she conducts studies, exploring tactics to decentralize her trials and avoiding the requirement for participants to stop at a quick building. “We’ve looked at how best to conduct this clinical trial. “in the patient’s community,” Sabo said.
Sabo helped set up sets of cell studies: He swapped out recreational autocellular tests that contained everything needed for an assay, added blood tests, labs to test that blood and high-tech devices like those used to scan eyes for disease. Then, the RV can simply be taken to a nursing home.
“These sets of cell studies have allowed us to succeed in a patient population that reflects the patients we are trying to treat,” Sabo said.
The digital generation has been reshaped from an opportunity to practice the pandemic.
“Before the pandemic, other people were interested and less enthusiastic,” Au said. “They are more willing to generate after the pandemic. “
The elderly, who thought they couldn’t use computers, have adapted. “If a global pandemic prevents them from doing what they need to do,” he said, “they will. “
Telemedicine also avoids “white coat syndrome,” in which patients get nervous when they want to see a provider at a fitness center, Forrester’s Schibell said. People feel more comfortable in their own environment, he says. “You get a lot more knowledge and a more realistic attitude about that patient. “
The expansion of the high-speed web in rural areas, expected over the next two to five years, will allow corporations to conduct more decentralized clinical trials with more varied populations, Schbell said.
“When you think about the potential benefits of decentralized clinical trials to get real-world evidence, assistance companies stand out from the competition, help build trust. . . This is the most productive long-term form of pharmaceuticals. “
