FDA warning letter

3 min read

The FDA dropped a lengthy, extremely critical warning letter on a supplier of unproven exosome product called EUCYT Laboratories. For broader context, exosome therapy has somehow burst onto the scene when there’s no good data yet in my view to back up its use in the clinic. The FDA is taking notice with letters already sent to others including an untitled letter to Kimera Labs  and on the same date another to a physician who used Kimera products and was at one time amongst Kimera leadership, Doug …Read More

Should we call it stem cell synchronicity for stem cell supplier firm Invitrx? What was it about March 16? Sometimes strange things happen in the stem cell world such as last week on March 16 I wrote that the FDA needs to do more about unproven exosomes, and then on the same day a new FDA warning letter went out to Invitrx mentioning almost as an aside an unapproved exosome product amongst many other products and issues. No, I don’t have some secret red telephone where I …Read More

Friday and Saturday showed a burst in FDA activity related to unproven stem cells and regenerative products including a warning letter to the unproven perinatal “stem cell” provider Liveyon. This was an unusual 48-hour period and a very good one for those who believe in science-based regenerative medicine but in my view a bad day for perinatal stem cell clinic and exosome suppliers. For general background on exosomes see these past The Niche posts. I’m sure there are a lot of hardworking folks at …Read More

As part of its stepped up approach to unproven stem cell marketing, the FDA issued another warning letter to a perinatal (birth-related) stem cell supplier. It’s interesting to see the FDA doing more specifically about suppliers and not just focusing on clinics. It seems that in some subsectors of the stem cell arena that certain suppliers are strong driving forces behind more patients being put at risk. Also, each supplier may enable dozens of clinics so there’s some logic here to the FDA putting …Read More

Yesterday we learned that the FDA issued a warning letter to the cord stem cell firm, Cord for Life. In this warning, the FDA indicated that the firm’s product is actually a drug product and lacks necessary pre-market approvals. In addition, the agency highlighted apparent deviations from CGMP practices. The most important part of the warning letter is the clarity it brings that, yes, allogeneic umbilical cord stem cell and other perinatal stem cell products generally are drugs requiring a cleared IND and a …Read More

Institutional review boards or IRBs are some of the biggest enablers of risky, unproven stem cell clinics. We often see statements on stem cell clinic websites to the effect that they have approvals from IRBs so the clinic firms must think that patients like to see that. Why would specific IRBs approve for-profit “experiments” by stem cell clinics using unproven fat stem cell injections, which are now clearly defined by the FDA as unapproved drug products being marketed unlawfully by clinics? First, let’s ask …Read More

When the FDA has a major problem with something, it can issue a warning letter or more rarely it can file suit in court for an injunction against the particular party. The FDA has now done both of these things on different fronts with Beverly Hills stem cell clinic doctor and cosmetic surgeon, Dr. Mark Berman. Berman and his clinic partner, urologist Elliot Lander, run an adipose stem cell firm called California Stem Cell Treatment Center. This clinic seems effectively to also be the HQ …Read More

The US has been bursting at the seams with unproven stem cell clinics for years, which in my view necessitates some kind of bold action by the FDA and other governmental agencies so I’ve wondered what new FDA Commissioner Dr. Scott Gottlieb would do on this front. The lead up to and beginning of a likely crackdown A subset of these clinics are particularly risky and egregious in their behavior. While this subset constitutes may be “only” one or two hundred such clinics out …Read More

Do the hundreds of unproven fat stem cell clinics in the U.S. like Stemgenex have a tenable future without working with the FDA? It seems less certain now in 2018 than it did in 2017, and that’s a good thing in my view. Stemgenex received an FDA warning letter yesterday that included a list of many troubling issues at the clinic. This warning letter just adds to difficult issues facing this clinic firm including a proposed class action patient lawsuit against it that that could get class …Read More

We need medical innovations, but what is the appropriate way for agencies like the FDA to regulate the process and fight bogus interventions based solely on hype? Without innovation, medicine becomes stagnant and hope fades for patients who have any one of numerous conditions that are currently inadequately addressed by medicine. I can relate on a personal level to need for medical innovation as a survivor of a very serious form of prostate cancer. I’m currently in long term remission 4+ years after surgery, …Read More
