As More People Crowdfund Medical Bills, Beware of Dubious Campaigns
Individuals seeking funding for experimental therapies may enroll in legitimate clinical trials -- or fall prey to snake oil.
Nearly a decade ago, Jamie Anderson hit his highest weight ever: 618 pounds. Depression drove him to eat and eat. He tried all kinds of diets, losing and regaining weight again and again. Then, four years ago, a friend nudged him to join a gym, and with a trainer's guidance, he embarked on a life-altering path.
Ethicists become particularly alarmed when medical crowdfunding appeals are for scientifically unfounded and potentially harmful interventions.
"The big catalyst for all of this is, I was diagnosed as a diabetic," says Anderson, a 46-year-old sales associate in the auto care department at Walmart. Within three years, he was down to 276 pounds but left with excess skin, which sagged from his belly to his mid-thighs.
Plastic surgery would cost $4,000 more than the sum his health insurance approved. That's when Anderson, who lives in Cabot, Arkansas, a suburb outside of Little Rock, turned to online crowdfunding to raise money. In a few months last year, current and former co-workers and friends of friends came up with that amount, covering the remaining expenses for the tummy tuck and overnight hospital stay.
The crowdfunding site that he used, CoFund Health, aimed to give his donors some peace of mind about where their money was going. Unlike GoFundMe and other platforms that don't restrict how donations are spent, Anderson's funds were loaded on a debit card that only worked at health care providers, so the donors "were assured that it was for medical bills only," he says.
CoFund Health was started in January 2019 in response to concerns about the legitimacy of many medical crowdfunding campaigns. As crowdfunding for health-related expenses has gained more traction on social media sites, with countless campaigns seeking to subsidize the high costs of care, it has given rise to some questionable transactions and legitimate ethical concerns.
Common examples of alleged fraud have involved misusing the donations for nonmedical purposes, feigning or embellishing the story of one's own unfortunate plight or that of another person, or impersonating someone else with an illness. Ethicists become particularly alarmed when medical crowdfunding appeals are for scientifically unfounded and potentially harmful interventions.
About 20 percent of American adults reported giving to a crowdfunding campaign for medical bills or treatments, according to a survey by AmeriSpeak Spotlight on Health from NORC, formerly called the National Opinion Research Center, a non-partisan research institution at the University of Chicago. The self-funded poll, conducted in November 2019, included 1,020 interviews with a representative sample of U.S. households. Researchers cited a 2019 City University of New York-Harvard study, which noted that medical bills are the most common basis for declaring personal bankruptcy.
Some experts contend that crowdfunding platforms should serve as gatekeepers in prohibiting campaigns for unproven treatments. Facing a dire diagnosis, individuals may go out on a limb to try anything and everything to prolong and improve the quality of their lives.
They may enroll in well-designed clinical trials, or they could fall prey "to snake oil being sold by people out there just making a buck," says Jeremy Snyder, a health sciences professor at Simon Fraser University in British Columbia, Canada, and the lead author of a December 2019 article in The Hastings Report about crowdfunding for dubious treatments.
For instance, crowdfunding campaigns have sought donations for homeopathic healing for cancer, unapproved stem cell therapy for central nervous system injury, and extended antibiotic use for chronic Lyme disease, according to an October 2018 report in the Journal of the American Medical Association.
Ford Vox, the lead author and an Atlanta-based physician specializing in brain injury, maintains that a repository should exist to monitor the outcomes of experimental treatments. "At the very least, there ought to be some tracking of what happens to the people the funds are being raised for," he says. "It would be great for an independent organization to do so."
"Even if it appears like a good cause, consumers should still do some research before donating to a crowdfunding campaign."
The Federal Trade Commission, the national consumer watchdog, cautions online that "it might be impossible for you to know if the cause is real and if the money actually gets to the intended recipient." Another caveat: Donors can't deduct contributions to individuals on tax returns.
"Even if it appears like a good cause, consumers should still do some research before donating to a crowdfunding campaign," says Malini Mithal, associate director of financial practices at the FTC. "Don't assume all medical treatments are tested and safe."
Before making any donation, it would be wise to check whether a crowdfunding site offers some sort of guarantee if a campaign ends up being fraudulent, says Kristin Judge, chief executive and founder of the Cybercrime Support Network, a Michigan-based nonprofit that serves victims before, during, and after an incident. They should know how the campaign organizer is related to the intended recipient and note whether any direct family members and friends have given funds and left supportive comments.
Donating to vetted charities offers more assurance than crowdfunding that the money will be channeled toward helping someone in need, says Daniel Billingsley, vice president of external affairs for the Oklahoma Center of Nonprofits. "Otherwise, you could be putting money into all sorts of scams." There is "zero accountability" for the crowdfunding site or the recipient to provide proof that the dollars were indeed funneled into health-related expenses.
Even if donors may have limited recourse against scammers, the "platforms have an ethical obligation to protect the people using their site from fraud," says Bryanna Moore, a postdoctoral fellow at Baylor College of Medicine's Center for Medical Ethics and Health Policy. "It's easy to take advantage of people who want to be charitable."
There are "different layers of deception" on a broad spectrum of fraud, ranging from "outright lying for a self-serving reason" to publicizing an imaginary illness to collect money genuinely needed for basic living expenses. With medical campaigns being a top category among crowdfunding appeals, it's "a lot of money that's exchanging hands," Moore says.
The advent of crowdfunding "reveals and, in some ways, reinforces a health care system that is totally broken," says Jessica Pierce, a faculty affiliate in the Center for Bioethics and Humanities at the University of Colorado Anschutz Medical Campus in Denver. "The fact that people have to scrounge for money to get life-saving treatment is unethical."
Crowdfunding also highlights socioeconomic and racial disparities by giving an unfair advantage to those who are social-media savvy and capable of crafting a compelling narrative that attracts donors. Privacy issues enter into the picture as well, because telling that narrative entails revealing personal details, Pierce says, particularly when it comes to children, "who may not be able to consent at a really informed level."
CoFund Health, the crowdfunding site on which Anderson raised the money for his plastic surgery, offers to help people write their campaigns and copy edit for proper language, says Matthew Martin, co-founder and chief executive officer. Like other crowdfunding sites, it retains a few percent of the donations for each campaign. Martin is the husband of Anderson's acquaintance from high school.
So far, the site, which is based in Raleigh, North Carolina, has hosted about 600 crowdfunding campaigns, some completed and some still in progress. Campaigns have raised as little as $300 to cover immediate dental expenses and as much as $12,000 for cancer treatments, Martin says, but most have set a goal between $5,000 and $10,000.
Whether or not someone's campaign is based on fact or fiction remains for prospective donors to decide.
The services could be cosmetic—for example, a breast enhancement or reduction, laser procedures for the eyes or skin, and chiropractic care. A number of campaigns have sought funding for transgender surgeries, which many insurers consider optional, he says.
In July 2019, a second site was hatched out of pet owners' requests for assistance with their dogs' and cats' medical expenses. Money raised on CoFund My Pet can only be used at veterinary clinics. Martin says the debit card would be declined at other merchants, just as its CoFund Health counterpart for humans will be rejected at places other than health care facilities, dental and vision providers, and pharmacies.
Whether or not someone's campaign is based on fact or fiction remains for prospective donors to decide. If a donor were to regret a transaction, he says the site would reach out to the campaign's owner but ultimately couldn't force a refund, Martin explains, because "it's hard to chase down fraud without having access to people's health records."
In some crowdfunding campaigns, the individual needs some or all the donated resources to pay for travel and lodging at faraway destinations to receive care, says Snyder, the health sciences professor and crowdfunding report author. He suggests people only give to recipients they know personally.
"That may change the calculus a little bit," tipping the decision in favor of donating, he says. As long as the treatment isn't harmful, the funds are a small gesture of support. "There's some value in that for preserving hope or just showing them that you care."
An Investigational Drug Offers Hope to Patients with a Disabling Neuromuscular Disease
Robert Thomas was a devoted runner, gym goer, and crew member on a sailing team in San Diego when, in his 40s, he noticed that his range of movement was becoming more limited.
He thought he was just getting older, but when he was hiking an uphill trail in Lake Tahoe, he kept tripping over rocks. "I'd never had this happen before," Robert says. "I knew something was wrong but didn't know what it was."
It wasn't until age 50 when he was diagnosed with Charcot-Marie-Tooth disease. The genetic disorder damages the peripheral nerves, which connect the brain and spinal cord to the rest of the body. This network of nerves is responsible for relaying information and signals about sensation, movement, and motor coordination. Over time, the disease causes debilitating muscle weakness and the loss of limb control.
Charcot-Marie-Tooth usually presents itself in childhood or in a person's teens, but in some patients, like Robert, onset can be later in life. Symptoms may include muscle cramping, tingling, or burning. Many patients also have high foot arches or hammer toes — toes that curl from the middle joint instead of pointing forward. Those affected often have difficulty walking and may lose sensation in their lower legs, feet, hands, or forearms. One of the most common rare diseases, it affects around 130,000 people in the United States and 2.8 million worldwide.
Like many people with Charcot-Marie-Tooth, or CMT, Robert wears corrective braces on his legs to help with walking. Now 61, he can't run or sail anymore because of the disease, but he still works out regularly and can hike occasionally. CMT also affects his grip, so he has to use special straps while doing some exercises.
For the past few years, Robert has been participating in a clinical trial for an investigational CMT drug. He takes the liquid formulation every morning and evening using an oral syringe. Scientists are following patients like Robert to learn if their symptoms stabilize or improve while on the drug. Dubbed PXT300, the drug was designed by French biopharmaceutical company Pharnext and is the farthest along in development for CMT. If approved, it would be the first drug for the disease.
Currently, there's no cure for CMT, only supportive treatments like pain medication. Some individuals receive physical and occupational therapy. A drug for CMT could be a game-changer for patients whose quality of life is severely affected by the disease.
Genetic Underpinnings
CMT arises from mutations in genes that are responsible for creating and maintaining the myelin sheath — the insulating layer around nerves. Pharnext's drug is meant to treat patients with CMT1A, the most common form of the disease, which represents about half of CMT cases. Around 5% of those with CMT1A become severely disabled and end up in wheelchairs. People with CMT1A have an extra copy of the gene PMP22, which makes a protein that's needed to maintain the myelin sheath around peripheral nerves.
Typically, an individual inherits one copy of PMP22 from each parent. But a person with CMT1A receives a copy of PMP22 from one parent and two copies from a parent with the disease. This extra copy of the gene results in excess protein production, which damages the cells responsible for preserving and regenerating the myelin sheath, called Schwann cells.
The myelin sheath helps ensure that a signal from the brain gets carried to nerves in the muscles so that a part of the body can carry out a particular action or movement. This sheath is like the insulation on an electrical cord and the action is like a light bulb. If the insulation is fine, the light bulb turns on. But if the insulation is frayed, the light will flicker.
"The same happens to these patients," says David Horn Solomon, CEO of Pharnext. "The signal to their muscle is weak and flickers." Over time, their muscles become weaker and thinner.
The PMP22 gene has proven difficult to target with a drug because it's located in a protected space — the Schwann cells that make up the insulation around nerves. "There's not an easy way to tamp it down," Solomon says.
Another company, Acceleron Pharma of Cambridge, Massachusetts, was developing an injectable CMT drug meant to increase the strength of leg muscles. But the company halted development last year after the experimental drug failed in a mid-stage trial. While the drug led to a statistically significant increase in muscle volume, it didn't translate to improvements in muscle function or quality of life for trial participants.
Made by Design
Pharnext's drug, PXT3003, is a combination of three existing drugs — baclofen, a muscle relaxant; naltrexone, a drug that decreases the desire for alcohol and opioids; and sorbitol, a type of sugar alcohol.
The company designed the drug using its artificial intelligence platform, which screened 20,000 existing drugs to predict combinations that could inhibit the PMP22 gene and thereby lower protein production. The AI system narrowed the search to several hundreds of combinations and Pharnext tested around 75 of them in the lab before landing on baclofen, naltrexone, and sorbitol. Individually, the drugs don't have much effect on the PMP22 gene. But combined, they work to lower how much protein the gene makes.
"How the drug inside the cell reduces expression isn't quite clear yet," says Florian Thomas, director of the Hereditary Neuropathy Center, and founding chair and professor in the department of neurology at Hackensack University Medical Center and Hackensack Meridian School of Medicine in New Jersey (no relation to Robert Thomas, the CMT patient). "By reducing the amount of protein being produced, we hopefully can stabilize the nerves."
In rodents genetically engineered to have the PMP22 gene, the drug reduced protein levels and delayed onset of muscle weakness when given to rats. In another animal study, the drug increased the size of the myelin sheath around nerves in rats.
"Like humans with CMT, one of the problems the animals have is they can't grip things, their grip strength is poor," Solomon says. But when treated with Pharnext's drug, "the grip strength of these animals improves dramatically even over 12 weeks."
Human trials look encouraging, too. But the company ran into a manufacturing issue during a late-stage trial. The drug requires refrigeration, and as a result of temperature changes, crystals formed inside vials containing the high dose of the drug. The study was a double-blind trial, meaning neither the trial participants nor investigators were supposed to know who received the high dose of the drug, who received the low dose, and who received a placebo. In these types of studies, the placebo and experimental drug should look the same so that investigators can't tell them apart. But because only the high dose contained crystals, not the low dose or placebo, regulators said the trial data could be biased.
Pharnext is now conducting a new randomized, double-blind trial to prove that its drug works. The study is recruiting individuals aged 16 through 65 years old with mild to moderate CMT. The company hopes to show that the drug can stop patients' symptoms from worsening, or in the best case scenario, possibly even improve them. The company doesn't think the drug will be able to help people with severe forms of the disease.
"In neurologic disease, you're looking for plasticity, where there's still the possibility of stabilization or reversal," Solomon says. Plasticity refers to the ability of the nervous system to change and adapt in response to stimuli.
Preventing Disability
Allison Moore, a CMT patient and founder and CEO of the Hereditary Neuropathy Foundation, has been following drug development for CMT since she founded the organization in 2001. She says many investigational drugs haven't moved forward because they've shown little success in animals. The fact that Pharnext's drug has made it to a late-stage human trial is promising, she says.
"It's really exciting," Moore says. "There's a chance that if you take the drug early before you're very severe, you'll end up not developing the disease to a level that's super disabling."
CMT has damaged Moore's peroneal nerve, a main nerve in the foot. As a result, she has foot drop, the inability to lift the front part of her foot, and needs to wear leg braces to help her walk. "The idea that you could take this early on and that it could stop progression, that's the hope that we have."
Thomas, the neurologist, says a drug doesn't have to be a cure to have a significant impact on patients. "If I have a CMT patient who's 50 years old, that patient will be more disabled by age 60," he says. "If I can treat that person with a drug, and that person is just as disabled at age 60 as they were at age 50, that's transformative in my mind."
While Robert Thomas says he hasn't noticed a dramatic improvement since he's been on the drug, he does think it's helping. Robert is now in an open-label study, which means he and his health provider are aware that he's receiving the drug.
When the COVID-19 pandemic hit, manufacturing and supply chain disruptions meant that Robert was without the trial drug for two months. When his medication ran out, his legs felt unstable again and walking was harder. "There was a clear distinction between being on and off that medication," he says.
Pharnext's current trial will take about a year and a half to complete. After that, the FDA will decide on whether to approve the drug for CMT patients.
As scientists learn more about the PMP22 gene and the more than 100 other genes that when mutated cause CMT, more precise treatments could be possible. For instance, scientists have used the gene-editing tool CRISPR to correct a CMT-causing mutation in human cells in the lab. The results were published August 16 in the journal Frontiers in Cell and Developmental Biology.
Pharnext is also interested in pursuing genetic treatments for CMT, but in the meantime, repurposed drugs may be the best shot at helping patients until more advanced treatments are available.
