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. What’s the backstory with Invitrx? I wrote last year about …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

FDA Commissioner Scott Gottlieb has used very strong language to describe stem cell clinics including the phrase “bad actors”, but so far we haven’t seen much …Read More

The FDA’s CBER branch recently issued a warning letter to Amniotic Therapies, LLC. The warning letter pertains to both AlphaGEMS-related products that are used by a number of stem cell clinics as well as problems determined at the manufacturing facility. I went to the Amniotic Therapies website, but perhaps not coincidentally it is down, which could be due to the FDA warning. An archive of the site (screenshot above) provides information on their products. Notably, CBER described the company’s products as unapproved biological drugs …Read More

The FDA continues to be very active with warning letters against makers of stem cell cosmetics even as it has been relatively dormant on stem cell clinics. You can read past posts on the long series of warning letters to manufacturers of stem cell cosmetic cream. Three new warning letters to stem cell cream makers popped up on the FDA site recently to makers Lavian Ltd, Sircuit Skin, and Annemarie Gianni Skin Care LLC. Lavian markets something called Resurgent Stem Cell Firming Activator, which the …Read More
