FDA Warning Letter

4 min read

What’s been going on in the stem cell and regenerative medicine field over the past week and what are some worthwhile things to read? Today’s post has recommended recent reads from the scientific literature and the media. I’ve also got our weekly stem cell/regenerative medicine quiz question and the answer to last week’s. You can check out last week’s recommended reads here, which has last week’s quiz question. Toward the bottom of the post there’s also a “blast from the past” link to a piece …Read More

The FDA has stem cell clinics squarely on its radar screen now and it’s pulling the trigger with many letters going out to this problematic industry. In the past, sometimes years went by with no letters at all or one letter in total to stem cell clinics so this marks a major shift. Background on lead-up to wave of FDA activity I count 7 letters in a less than two-month span from mid-March to now, which may be the most in history in the …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

Umbilical “stem cell” supplier Liveyon has suspended sales of its products according to the WaPo after a harsh FDA warning letter. While not fully shutting off the tap to the perinatal stem cell clinic universe, as other suppliers including in Utah seem to be continuing, this Liveyon voluntary hold will equal a major reduction in supply. Why did Liveyon chose to halt sales at least for the moment? By comparison other clinic-related firms have continued business as usual despite various FDA actions against them …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

The FDA just sent another untitled letter to a producer of a potentially non-compliant perinatal “stem cell” product that may be an unapproved drug. This follows past non-warning letters and/or inspection reports made public to Liveyon, R3 Stem Cell, Stemell, and others. RAPS has more on the story of the new letter here. This newest untitled letter went to RichSource Stem Cells, Inc. and its CEO Sara Oracle, a firm which markets an unusual “combo” product described this way by the FDA, “a combination …Read More

I finished listening to the first 6 episodes of the Bad Batch podcast last week. The series is by medical journalist Laura Beil. I think there will be a 7th episode that’s a Q&A. I highly recommend listening to the series even if parts are wrenching at times like how much patients and families have been hurt. It’s important to know that reality and to hear directly from the real people who’ve been hurt. The podcast focuses in large part on a supplier called …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

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
