The Problem with Pop-Up Stem-Cell Clinics


By KHN senior correspondent Emily Bazar

A website for five affiliated stem-cell clinics hails a breakthrough for Parkinsons disease: Stem Cells Replace Damaged Nerves, Reverse Symptoms.

For those of you whose livesor whose loved ones liveshave been upended by chronic or incurable conditions such as Parkinsons, thats just the kind of breakthrough youve been waiting for.

But heres some advice about these and other for-profit stem-cell treatments that you probably dont want to hear:

Steer clear of them. Theyre probably taking advantage of you and its probably unproven, says Lawrence Goldstein, director of the Sanford Stem Cell Clinical Center at UC San Diego Health.

Stem-cell science is a relatively new field. Stem cells hold great potential for medicine because of their ability to develop into different types of cells in the body, and to repair and renew tissue.

But so far, the only stem cell-treatments approved for wide use in the U.S. involve transplants from bone marrow or blood for patients with certain cancers and other disorders, says Sidney Golub, director of the Sue and Bill Gross Stem Cell Research Center at the University of California, Irvine.

Meanwhile, dozens of experimental stem-cell treatments are being tested across the country in clinical trials on human subjects.

There are some really exciting developments showing great promise, but they are unproven at present, Golub says.

If most stem-cell therapies are unproven, how is it that nearly 600 clinics across the country offer costly stem-cell treatments for both cosmetic and medical purposes, ranging from spinal-cord injuries to breast augmentation?

California has 113 of these clinics, more than any other state, according to stem-cell researchers Leigh Turner of the University of Minnesota and Paul Knoepfler of the University of California, Davis. Florida comes in second with 71, followed by Texas with 37.

Many of these clinics say they use stem cells derived from patients own fat and, for related reasons, argue that their treatments are exempt from the U.S. Food and Drug Administrations rigorous approval process.

Their websites show heart-wrenching testimonials from patients who have undergone treatments and believe they have benefitted. The treatments can cost $15,000, $25,000 or more, and generally arent covered by health insurance.

If youre swayed by the testimonials, if youve tried every other treatment, and even if you have the money to burn, you should still steer clear, experts say.

If somebody is telling you something thats too good to be true, its too good to be true, Golub says.

In addition to spending thousands of dollars on a therapy that may not help, you could experience undesirable medical side effects, they warn.

The risk is far greater than the potential benefit, says Mary Bass, director of public policy at Americans for Cures, a patient advocacy group that supports stem-cell research for chronic diseases and injuries.

There are really no shortcuts in the scientific discovery process. Shortcuts come at grave cost to patients health, now or down the line, Bass says.

The Food and Drug Administration, too, said in a statement for consumers that it is concerned that patients may be vulnerable to unscrupulous providers of stem-cell treatments that are illegal and potentially harmful.

Kevin McCormack, director of patient advocate outreach for the California Institute for Regenerative Medicine (CIRM), the states stem-cell agency, acknowledges that patients dont want to hear this kind of advice.

Theyve often explored every other option and dont have anything left, McCormack says.

But there may be something you can do, he says: Search for a scientifically sound clinical trial that is testing a stem-cell therapy for your condition.

One trustworthy place to look, McCormack says, is the Alpha Stem Cell Clinics Networkthree clinics in Southern California specializing in stem-cell clinical trials that are funded by CIRM. They have more than 20 trials underway for conditions ranging from HIV to ovarian cancer, he says.

If theres something at one of those clinics, you know its legitimate and as safe as can be, McCormack says.

To find other stem-cell clinical trials, start with the government-run database.

But be cautious. Some for-profit stem-cell clinics post on that site, and patients who want to participate in their studies must pay for the cost of the treatment.

If you identify a trial that might fit your situation, do some digging, says Cathy Danielson, a stem-cell patient advocate based in Oregon.

Start asking questions, start posting on online forums, she says. Ask who funded it. Follow the money.

Goldstein urges patients to look for trials that are conducted by academic medical centers or nonprofit medical institutions, and to ask study sponsors if they have received FDA approval for their trials.

Patients will recognize legitimate clinical trials because, in general, they wont be charged for the cost of the treatment, he says.

Finally, if you find a trial, theres no guarantee youll receive the experimental stem-cell treatment. Thats because in most trials, some participantschosen randomlywill receive either a placebo or the current standard of care, while others will get the experimental treatment.

In other words, there are obstacles to obtaining stem-cell therapy at this point.

But things are hopeful, Bass says.

Were really on the verge of great discoveries. The hard part is remembering to have the patience and understanding about the scientific discovery process.
