I wouldn't do stem cells for decades yet, nothing has truly been proven.

Doris Tyler lay on the examining table as the doctor
stuck a long, thin tube into her belly. The doctor pulled back a
plunger, and the syringe quickly filled with yellow blobs tinged with
pink.
“Look at that beautiful fat coming out.
Liquid gold!” one of the clinic’s staff exclaimed in a video of the
procedure provided to The Washington Post.
Hidden
in that fat were stem cells with the amazing power to heal, the Stem
Cell Center of Georgia had told Tyler. The clinic is one of hundreds
that have popped up across the country, many offering treatments for
conditions from Parkinson’s disease to autism to multiple sclerosis.
Federal
regulators have not approved any of their treatments, and critics call
such clinics modern-day snake-oil salesmen. But on that day in 2016,
Tyler trusted the clinic to extract stem cells from her fat and inject
them into her eyes, where she was told they could halt or even cure the
macular degeneration threatening her sight.
Five
days after the injections, the clinic was boasting online that it had
performed the first such treatment in Georgia for macular degeneration.
On Facebook, the clinic called Tyler “our fabulous patient!” and urged others with her disease to book an appointment.
But by then, Tyler’s vision was getting blurry.
Within
weeks, the retina in her left eye detached. Then went the retina in her
right eye, according to a lawsuit Tyler and her husband filed in March
against the clinic. Surgery after surgery failed to repair the damage.
She quickly lost the ability to read large-text print. She could no
longer make out the faces of her seven grandchildren.
Within months, she said, she was completely blind.
“We trusted these people. We never questioned that they knew what they were doing,” Tyler said at her Florida home.

The
Tylers’ lawsuit alleges negligence by the clinic that treated her, the
network to which it belongs and an outside eye doctor. The clinic’s
owner and employees and the eye doctor declined to answer repeated calls
and emailed questions. The co-founders of the clinic network said
neither it nor the Georgia facility did anything wrong.
For
years, such direct-to-consumer stem cell clinics have expanded mostly
unchallenged. Cases like Tyler’s, however, are prompting lawsuits and
new efforts by state and federal regulators to rein in potentially
dangerous and worthless treatments.
Last year, California passed a law
requiring
stem cell clinics to post warnings that their treatments were
unapproved, and Washington’s legislature passed a similar law this year.
North Dakota’s attorney general is investigating a Bismarck clinic. And
the Federation of State Medical Boards is exploring
ways to increase oversight of the clinics.
In
interviews, Food and Drug Administration Commissioner Scott Gottlieb
and his predecessor blamed the agency’s limited resources for the lack
of aggressive action in the past. Since last summer, Gottlieb has
promised to pursue “unscrupulous actors” who he says are putting the promising field of stem cell therapies at risk.
The
agency, which had issued only seven warning letters in seven years to
stem cell clinics and suppliers, has sent two such letters since August.
It also ordered the seizure of an experimental concoction made of stem
cells and given to cancer patients.
Late last
year, officials clarified previously murky policies to assert that many
of the treatments clinics offer are unapproved drugs, a key point of
contention. The facilities argue they aren’t subject to FDA regulation
because they use surgical procedures to administer patients’ own cells —
meaning they aren’t making new drugs.
But the
agency now insists that their therapies require advance approval because
the cells are intended to treat diseases and undergo substantial
processing before being used in ways that are different from their
original purposes.
Acknowledging the difficulty
of curbing the entire booming industry, FDA officials say their
crackdown will first focus on high-risk procedures such as injections
into the brain, spinal cord and eye — rather than less risky ones, such
as shots into achy joints.
This month, Sen. Charles E. Grassley (R-Iowa) sent a letter to the FDA, pushing for stronger action.
Grassley cited the cases of three women
who suffered permanent loss of vision
at a Florida facility called U.S. Stem Cell Clinic. He asked what has
been done to ensure such dangerous procedures aren’t performed again.
Clinic
operators say desperately ill patients have a right to use their own
cells for experimental therapies. They say their treatments have the
ability to find and repair damaged tissues and organs, and they cite
online testimonials from satisfied customers as evidence.
Regulators
and researchers disagree, saying strict regulations do apply because
the clinics are essentially conducting human experiments without proper
oversight.
“What they’re really selling is
false hope,” said Timothy Caulfield, a health law professor at the
University of Alberta. “It’s science-ploitation. They’re taking a
legitimate and developing field of science and using it to prey on
patients who are desperate for a cure.”

The
treatments are not covered by insurance. Many of the clinics’ patients
are old, sick and already struggling with medical bills. Some clinics
urge individuals who can’t afford their steep fees — which range from
$1,800 to more than $20,000 — to launch GoFundMe pages or take out
loans, according to patients and former employees.
Many of the practitioners remain defiant, saying patients need alternative treatments like theirs.
Mark
Berman is a Beverly Hills, Calif., plastic surgeon who co-founded Cell
Surgical Network, the nation’s largest group of independent stem cell
clinics, including the facility that injected material into Tyler’s
eyes. After the network learned of her complications, Berman said, it
directed all of its affiliated physicians to stop doing such injections
into the eye.
Berman said Tyler’s problem was
“virtually” the only serious adverse event to occur in his network in
treating almost 8,000 patients. But
an FDA report
in July 2017 listed four adverse cases, including Tyler’s. Berman said
the others were “very minor” and called the FDA’s concerns about patient
safety “sanctimonious garbage.”
“How do you
heal your body? You have to heal yourself,” Berman said. He said it’s
“asinine” for the FDA to call patients’ own cells a drug.
For Tyler, however, the debate over the clinics has come too late.
Before
the injections, she could still read large-print books and navigate her
home in Ocoee. But now she moves cautiously, clutching each piece of
furniture like a life raft. Her husband has learned to cook for them
both, and Tyler — a former music teacher who is 77 — had to quit her
church choir because she can no longer read the music.
“When
I wake up in the morning, one of the hardest things is opening my eyes
and seeing that everything is still dark,” she said recently. “And it’s
going to be this way until I go to sleep.”
Yet
what saddens her most, she said, is that she will never see her youngest
grandchildren grow up. In her mind’s eye, they are frozen at ages 1 and
3.

Researchers say there is
real promise in stem cells’
ability to self-renew and turn into other types of cells. They are
methodically developing stem cell therapies for many types of disorders,
including macular degeneration, which can destroy the central vision of
the eye. British researchers recently said in a peer-reviewed
clinical trial report that two patients who were implanted with an engineered stem cell patch to replace failing cells regained some vision.
But bringing such treatments — tested and refined in rigorous trials — safely to market will take years, experts say.
Only
a few stem cell therapies have been approved by the FDA, primarily
products made from placental and umbilical cord blood and used to treat
leukemia and other blood diseases.
No one
tracks how many injuries have occurred from unproven, direct-to-consumer
treatments. Such cases have become public in recent years only when
doctors write about them in medical journals or patients file lawsuits.
Two years ago, the New England Journal of Medicine published an account of a man who ended up with a
huge spinal growth
after getting fetal stem cell injections overseas. A 69-year-old woman
died in 2010 after a doctor at a Florida clinic injected bone marrow
stem cells into the arteries of her brain. In 2012, the same doctor
infused fat-derived stem cells into the bloodstream of a man who died
soon after, according to the findings of a state health department
administrative hearing. But it wasn’t until 2013 that Florida’s state
medical board
revoked that physician’s license.

the $8,900 fee for her procedure. (Zack Wittman for The Washington Post)
Financial
harm is also a hazard. Some clinics use high-pressure sales tactics
more typical of condominium time-shares than of medical procedures —
complete with recruitment seminars, on-the-spot discounts and emotional
patient-testimonial videos, according to patients and former employees
who attended such seminars.
Some clinics list their unapproved, paid procedures as “studies” on
ClinicalTrials.gov,
a database maintained by the National Institutes of Health. Critics say
they are using the database inappropriately to attract clients and give
their treatments an air of legitimacy.
Most
trials for new experimental therapies, unlike the stem cell clinic
procedures, are overseen as part of the FDA’s investigational new-drug
program and free for participants. But NIH doesn’t independently verify
the information or indicate whether a “trial” listed in the database was
reviewed by the FDA. The site recently
added more visible disclaimers to warn consumers. Grassley expressed concern in his recent letter to regulators that the database is being misused.
An
NIH spokesperson said the agency “does not assess the quality of
clinical research studies — that is the role of funders, regulators and
ethics review boards, among others.”
“We’re
afraid that these charlatans will besmirch the reputation of legitimate
work we have spent decades trying to bring to the clinic,” said Charles
Murry, director of the Institute for Stem Cell and Regenerative Medicine
at the University of Washington.
Patients
who say they benefit from treatments at stem cell clinics could be
experiencing the placebo effect or some biological improvement, Murry
said. For conditions like arthritis, “these cells may be able to talk to
our immune system and say, ‘Cool it,’ ” thus providing temporary relief
— like a weak steroid shot.
But unless such treatments are tested in rigorous trials, he said, there’s no way to know whether they are safe and effective.

The
first stem cell clinics popped up during the early 2000s in countries
with lax regulations — like China, Russia and South Korea — and targeted
desperate American “medical tourists.” U.S. doctors soon followed. For
many, especially plastic surgeons, sucking out patients’ adipose tissue,
or fat, was already routine.
Stem cell clinics
have exploded in number across the United States. In 2009, there were
two; today, there are at least 700 and likely hundreds more, according
to Leigh Turner, a University of Minnesota bioethicist, and Paul
Knoepfler, a stem cell biologist at the University of California at
Davis, who have
compiled a database. In the past four years, at least 150 new facilities have
opened every year.
The clinic that treated Tyler is in a sleepy suburb 40 minutes outside of Atlanta. It’s part of the
Ageless Wellness Center,
which business records show was founded in 2008 by Jamie Walraven, a
former emergency room physician, and nurse practitioner Linda Faulkner.
For
years, the two offered mostly Botox, laser hair removal and other
beauty services. In 2014, they added stem cell treatments to their
business model.
The Georgia clinic says on its
website
that adult stem cells derived from fat are capable of fixing various
defects and diseases throughout the body. In a promotional video for the
clinic, patients say injections reduced their neck and knee pain and
multiple sclerosis symptoms.
Many researchers
scoff at the idea that adult stem cells can circulate throughout the
body correcting almost any problem. “This idea of a magic bullet that
can go around and fill in gaps in the body is science fiction,” said
Sally Temple, co-founder of the Neural Stem Cell Institute in
Rensselaer, N.Y. She said she doubts there are any stem cells in the
processed material most clinics inject back into patients.
In a June 2016
advertisement
in a local newspaper, Walraven said her clinic had used fat-derived
stem cells to treat multiple sclerosis, osteoarthritis, stroke,
rheumatoid arthritis and Parkinson’s disease. In coming weeks, she
added, “We have an ophthalmologist who is going to treat three people
with macular degeneration.”
Tyler was the first of those patients.
In
the spring of 2016, as Tyler continued struggling with macular
degeneration, a family friend gave her and her husband a book, “The Stem
Cell Revolution.” In it, plastic surgeon Berman and his partner,
urologist Elliot Lander, recount how they developed their technique
partly from doctors in South Korea and Japan. They started treating
patients in California and later launched Cell Surgical Network, which
now totals more than 100 stem cell clinics nationwide, including the
Ageless Wellness Center facility that treated Tyler’s eyes.
For
a fee, Berman and Lander teach other doctors how to extract patients’
fat through liposuction and process it using a proprietary centrifuge
called the “Time Machine.” The machine and instruction cost about
$30,000, they said.
“People license our brand,
and what we give them is training and unlimited professional and
technical support,” Lander said. He said affiliated clinics are required
to provide Cell Surgical Network with the outcomes of their procedures
so it can track patients over time.
The two
doctors say the FDA, in taking a tougher stand, is acting on behalf of
the pharmaceutical industry, which doesn’t want competition for its
medicines.
Visitors to the
network website
who scroll down toward the bottom of its homepage are told that “stem
cell treatment is not approved by the FDA for any specific disease.” If
they click for details, they are told that the clinics’ therapies are
not being offered as “a cure for any condition, disease, or injury.”
But
the website lists dozens of diseases, including congestive heart
failure, muscular dystrophy and stroke that Cell Surgical Network is
“currently studying.” Patients are charged fees for treatments — in what
Berman calls “patient-funded research.”
Walraven, at the Georgia clinic, had never treated macular degeneration but seemed eager to try, the Tylers said.
According
to the lawsuit the couple filed in a Georgia state court, the clinic
said the treatment would improve Doris Tyler’s vision or, at worst, have
no effect.
To raise the $8,900 fee for her
procedure, the Tylers’ son set up a GoFundMe account that got an
enthusiastic response. “We love you, Doris!” one person
wrote on the site. “If you need extra belly fat, I’m MORE than happy to offer mine!” another said.
Walraven asked
Robert Halpern,
an Atlanta ophthalmologist, to perform the injections. In a June 30,
2016, letter that Tyler’s lawyer shared with The Washington Post,
Walraven sent Halpern a brochure explaining how he could become a
certified doctor within the network.
Halpern
injected Tyler’s right eye on Sept. 8, 2016. The next day he injected
her left eye, the lawsuit alleges. Injecting both eyes so close together
is a safety risk, eye experts say, because if something goes wrong,
patients can be left entirely blind.
Thomas
Albini, an ophthalmologist at the University of Miami’s Bascom Palmer
Eye Institute, treated Tyler after the stem cell procedure but could not
reverse the damage. Albini, retained as an expert witness in the
Tylers’ lawsuit, said he believes the processed fat that was injected
into Tyler’s eyes may have contained fibroblasts — connective tissue
cells that can cause scarring and “literally pull the retinas off the
wall of the eye,” in a process called proliferative vitreoretinopathy.
The
Georgia clinic, Walraven, Faulkner and Halpern declined to answer
repeated calls and emailed questions. None has responded in court to the
allegations.
Lander said all clinics in Cell
Surgical Network use a “very, very thorough” consent form that spells
out all the risks, such as, in Tyler’s case, her vision potentially
getting worse.
The Tylers’ lawyer, Andrew
Yaffa, said that was a “misrepresentation.” He said she was given one
consent form that said she would be participating in what was described
as a research study. Other forms warned of possible complications from
the injections, Yaffa said, but not from the stem cells themselves.

Yaffa
represented
two women who reached confidential settlements after losing vision
following stem cell injections for macular degeneration at U.S. Stem
Cell Clinic in southern Florida — among the cases detailed in a New
England Journal of Medicine article last year.
Berman
said the Georgia clinic that treated Tyler “did everything right,”
noting that a retina specialist performed the injections and that Cell
Surgical Network halted such eye injections as soon as he and Lander
heard about Tyler’s complications.
But Ajay
Kuriyan, a retinal specialist at the University of Rochester, said he
and other researchers have found dozens of clinics that continue to
market such eye injections on their websites. After writing that 2017
article on the three women who suffered severe eye damage at the Florida
facility, Kuriyan said he and his co-authors received a flurry of calls
about other cases.
“The problem is still there,” he said.

In August, the FDA sent a
warning letter to U.S. Stem Cell Clinic; in January, another
warning letter went
to American CryoStem Corp. in New Jersey, which processes and
distributes a fat-derived stem cell product. Both companies, the agency
said, were selling unapproved drugs — in the case of U.S. Stem Cell
Clinic, for heart disease, amyotrophic lateral sclerosis and diabetes,
among other diseases — and deviating from proper manufacturing
practices.
In response, CryoStem said it would
“actively engage with the agency to resolve these issues and continue to
improve our quality systems and processes.”
U.S.
Stem Cell Clinic told the FDA that it isn’t making a drug and isn’t
subject to agency regulation, and it asserted that patients have a right
to alternative treatments. It denied having sterility problems in its
operation. In an interview, Chief Science Officer Kristin Comella said
the clinic no longer does eye injections and “the cases have been
settled.”
Her goal, she added, is “to always
help people achieve health and help them feel good, and when they don’t,
it’s personally devastating.”
The company continues to expand. It recently opened another facility at a seniors community in central Florida, and it
announced
plans to inject stem cell mixtures into patients’ penises to treat
erectile dysfunction — a $4 billion market, a company release noted.
The FDA last summer also had U.S. marshals
seize
live vaccinia virus vaccine, used to protect people at risk of
smallpox, that was discovered during an agency inspection of a San Diego
biotech company named StemImmune. The vaccine, combined with stem
cells, was being injected directly into tumors of terminally ill cancer
patients and administered intravenously at Lander’s and Berman’s two
California clinics, the agency said. The FDA said the vaccine posed
“substantial risks,” including myocarditis, an inflammation of the heart
muscle.
Allan Camaisa, chief executive of
StemImmune, said the company is “cooperating fully” and will continue
talking to officials about cancer treatments. Berman said the FDA
misrepresented what the clinics were doing.
In recent months, the FDA has stepped up its oversight efforts. It
spelled out procedures
designed to speed approval of legitimate stem cell therapies. It also
detailed under what circumstances direct-to-consumer stem cell
treatments require agency approval.
Of the
decision to focus its enforcement on “high-risk” procedures, Gottlieb
said there’s only so much that can be done: “You can’t boil the ocean.”
Many
researchers say the moves fall short. Temple, the stem cell scientist,
is blunt: “I’d like the FDA to be firmly shutting all these places
down.”
