This clinic’s experimental stem cell treatment blinded patients. Years later, the government is still trying to stop it.

In the summer of 2015, ophthalmologist Thomas Albini examined a patient who had suddenly lost vision in both eyes. The woman, 78, had macular degeneration and had visited a Miami clinic offering a new treatment: injections of stem cells made from fat in her belly.
Instead of getting better, the woman’s vision deteriorated significantly. Peering into her eyes, Albini said, he saw clumps of blood floating inside.
The next day, a second patient appeared in Albini’s emergency room at the University of Miami complaining of blindness and searing pain after receiving eye injections from the same company, U.S. Stem Cell. Albini reported the cases to the U.S. Food and Drug Administration, urging an investigation.
Now, the FDA is suing to stop the company’s treatments in federal court in Fort Lauderdale, Fla., in one of the government’s most aggressive actions against the burgeoning stem cell business. With the judge expected to rule any day on the government’s charge that U.S. Stem Cell is “openly violating the law and endangering patients,” legal experts say the case could constrain a lucrative industry accused by doctors, lawyers and federal officials of harming dozens of people.

But the FDA’s slow response has permitted U.S. Stem Cell to continue operating four years after those first reports of blindness. Although the company stopped injecting its fat-derived treatments into eyes after the patients sued, it continues to sell the therapy to people with spinal injuries, Parkinson’s disease, multiple sclerosis and other serious chronic conditions.
Last spring, just three weeks after the government filed suit, another patient had a catastrophic reaction after visiting a South Miami clinic affiliated with U.S. Stem Cell. The 59-year-old woman felt faint and started vomiting two hours after receiving injections for arthritis pain.
Her case — which has not previously been reported — was described in an “adverse event” report filed with the FDA and obtained by The Washington Post through the Freedom of Information Act, as well as in a second report filed with the Florida Health Department. The woman was taken to a hospital, the reports said, and spent more than a month in a coma.

“It’s frustrating that these clinics are still operating, and surprising that authorities aren’t moving faster — even now,” said Albini, an ophthalmology professor who has emerged as a vocal critic of the stem cell industry.
FDA officials declined to discuss the lawsuit, or respond to critics who say the agency should have sought a temporary restraining order to shut down U.S. Stem Cell years ago. Former FDA officials said that such orders are extraordinarily difficult to obtain, and that the agency is wary that a loss in court could undermine its ability to regulate the industry.
“People have the right to legal recourse,” said Robert Califf, who served as FDA commissioner during the Obama administration. “You don’t want a situation where a judge could make a ruling that would be a bad precedent. The FDA has to be very careful.”
