If you think this can help you, Austin Wolff said earnestly into the camera, its worth a shot .It can only help.

Wolff was speaking on a YouTube video produced for the Novus Center, a Studio City business run by his mother, Stephanie, selling stem cell-related products said to treat chronic pain, sexual performance issues and the effects of aging.

In recent weeks, Novus has begun directing its pitch at potential customers fearful about the effects of the novel coronavirus, implying that its stem cell exosome vapor the supplies for which can be shipped overnight to customers homes can improve lung strength, the immune system and ward off viruses and disease. (Exosomes are a form of cellular secretion.)

These are opportunistic businesses, and COVID-19 for them is an opportunity.

Novus videos bristle with formal disclaimers. Its not going to cure anything, Austin Wolff says on one video. You should only do this if you want to try it.

But the videos seem aimed at viewers desperate for any possible defense against a pandemic whose implacable spread seem to grow more frightening with every passing day.

Novus charges $10,000 for the shipment of vials containing the exosomes and nebulizing equipment. Stephanie Wolff says the business, which has been open for four years, has served about a dozen customers worried about COVID-19 in the last month or two.

Promoters of untested and unlicensed stem cell treatments have jumped into the coronavirus market with both feet, says Leigh Turner, a bioethicist at the University of Minnesota who has been tracking the spread of clinics pitching these treatments to consumers for years.

The direct-to-consumer clinics have pivoted their marketing message to treating or preventing COVID-19, Turner told me. Thats not really shocking, in a way; these are opportunistic businesses, and COVID-19 for them is an opportunity.

In a paper scheduled to be published shortly in the prestigious journal Cell Stem Cell, Turner examines how these businesses are preying on public fears and anxieties about the pandemic.

Typically, their claims fall short of actually promising cures or even specific treatments; that holds at bay the Food and Drug Administration, which has sought to shut down clinics offering unproven therapies for conditions such as Alzheimers, diabetes, multiple sclerosis and erectile dysfunction.

Some use the language of immune booster or preventive intervention, Turner says. Theyre not trying to treat somebody whos in an ICU bed. Its more the worried well theyre going after people who are anxious, fearful of the pandemic, and susceptible to claims that a stem cell procedure will reduce their chance of becoming infected.

These treatments can come with a healthy price tag, ranging hundreds to thousands of dollars. But they run up against one indisputable fact: There are no approved stem cell treatments for COVID-19.

Those are the words of Martin F. Pera, a leading stem cell researcher who is editor-in-chief of Stem Cell Reports, the open-access journal of the International Society for Stem Cell Research. The society issued a stern warning March 6 against claims that stem cells can be used to treat people infected with COVID-19.

As for the products sold by Novus, the FDA warned consumers in December that there are currently no FDA-approved exosome products. The agency stated that certain clinics across the country offering such products to patients deceive patients with unsubstantiated claims about the potential for these products to prevent, treat or cure various diseases or conditions.

Weve reported for years on the proliferation of clinics selling purported therapies based on stem cell injections costing as much as $15,000 each.

These treatments arent supported by scientific research, typically arent covered by insurance, and have been targets of an FDA crackdown. (Turner did groundbreaking work with UC Davis biologist Paul Knoepfler in 2016, sounding the alarm about the spread of these clinics.)

In early April, the FDA sent letters to two stem cell firms, Dynamic Stem Cell Therapy of Henderson, Nev., and Kimera Labs of Miramar, Fla., that it said had been marketing their products for the treatment or prevention of COVID-19 and warning them that any such products would have to meet regulatory standards for drugs. But the agency didnt explicitly threaten them with legal consequences. Kimera is the supplier of exosomes to Novus.

Frightened laypersons arent the only targets of claims for cellular treatments for COVID-19. So are decision-makers and government regulators.

The FDA came under fire in March when it issued an emergency use authorization to allow the prescribing of two antimalarial drugs, chloroquine and hydroxychloroquine, for COVID-19 patients. The action came after President Trump had been relentlessly promoting the drugs as potential game changers in the battle against COVID-19.

Less than a month later, the FDA issued a warning against using the drugs against COVID-19 because of reports of serious heart problems in COVID-19 patients who had taken them, as well as the absence of evidence that they were safe and effective for treating the disease.

It wouldnt be surprising to see more companies and clinics showing up in the media and on cable television hawking unsubstantiated stem cell treatments for COVID-19. On May 4, the San Diego stem cell firm Giostar issued a news release asserting that it had received approval for a COVID-19 clinical trial using stem cells to treat COVID-19 patients, under the approval of the United States Food and Drug Administration (FDA) expanded access for compassionate use program.

Is this plausible? Weve reported before that Giostar had made untrue claims about its scientific connections: Several legitimate stem cell scientists the firm listed as members of its scientific advisory board said they had no connection with Giostar and had repeatedly asked that their names be removed from its website. The company has also acknowledged that it had exaggerated the professional credentials of its co-founder and chairman, Anand Srivastava.

Giostars claim in its news release that it would conduct the clinical trial under the FDAs expanded access for compassionate use program is curious. That program, which allows doctors to prescribe unapproved drugs as a last resort for people suffering from life-threatening diseases with no established cure, covers patients for whom enrollment in a clinical trial is not possible.

In other words, there doesnt seem to be such a thing as a clinical trial conducted subject to the expanded access program.

Giostar didnt respond to our request for comment. The FDA would say only that it generally cannot disclose information about an unapproved application, which certainly suggests that Giostar hasnt won the approval it claims.

In the frenzied search for COVID-19 treatments, it may be difficult to distinguish promising efforts from those just grasping at the main chance.

What we have right now is a COVID-19 gold rush, Turner says. Businesses are seeing this as a terrific opportunity to get their applications for investigative new drug trials approved by the FDA a process that can take years and generally requires the submission of extensive evidence from lab and animal studies.

The direct-to-consumer pitches by clinics reviewed in Turners paper typically fuse pseudoscience, which is what theyre offering, with more credible forms of science. He found numerous references in these pitches to research from China, often of doubtful scientific significance.

A Pennsylvania clinic offering stem cell treatment to support lung health during COVID-19, for example, cited a report from a Beijing hospital where seven patients were injected with stem cells all saw significant improvement in COVID-19 related pneumonia, according to the clinics press news . It quoted its CEO stating, This goes to support the wide range of healing and restoration that can be provided by (stem cell) therapy.

However, as Turner observes, the report didnt specify the severity of the subjects pneumonia, the source of the stem cells, or results from a control group. At best you can say that no one seemed to be harmed, but its hard to draw any firm conclusions about efficacy.

The Novus Center hangs its pitch on what Stephanie Wolff describes as a study thats ongoing in China right now using exosomes to help with viral load, to help with inflammation of the lung, to help with pneumonia, to help with infection.

The reference, however, is to a clinical trial in Wuhan that had not even begun to recruit test subjects at the time of its latest public report, which is dated Feb. 25. The researchers didnt expect their trial to be completed until July 31.

As weve written before, the proliferation of stem cell clinics selling untested and unlicensed therapies has been a public health crisis for years. The COVID-19 pandemic will only deepen the crisis as clinics add the coronavirus to their menu of treatment claims.

Despite its crackdown campaign, the FDA has never taken strong enough action against this corner of the healthcare industry. It should act without delay to shut down opportunistic initiatives, or more innocent Americans will find their health, and their pocketbooks, at ever greater risk.
