Burst Biologics unapproved biologic used by Weill Cornell: was there a cover-up?

Burst Biologics, Christopher Jones

The New York Times just broke a story on Burst Biologics and Weill Cornell that fits with long-standing troubling questions about regenerative biologics producers. The story also bears on the doctors and hospitals like Weill Cornell that were or are customers of the suppliers. Further, what is the FDA’s role in all of this? The

Update on stem cells & cell therapy for COVID trials

cell therapy for COVID

From the beginning of the pandemic, I have been mostly skeptical about the idea of cell therapy for COVID including stem cell therapies. However, at the same time, I’ve closely followed the data, especially up until 2022. Now having just had a nasty bout with COVID myself for the first time this summer, I recently

WHYY oh WHYY: NPR puff piece on risky stem cell microneedling

I usually associate NPR with solid journalism so I was scratching my head about a recent puff piece by WHYY on stem cell microneedling.  Is this journalism or product promotion? The NPR piece by Maiken Scott doesn’t ask important questions. Scott received stem cell microneedling herself using a product from a company called AnteAGE. How

David Liu, human CRISPR

It’s funny how sometimes there are many new articles about one general topic like this week with heritable (and somatic) human CRISPR gene editing and related tech.  There are clear reasons for optimism in the somatic arena given advancing trials. Germline editing remains highly questionable in my view even just technically. Then there are loads

Does Medicare cover stem cell therapy? Mostly no & it’s poised to recoup tens of millions

Regenative labs, does Medicare cover stem cell therapy?

Does Medicare cover stem cell therapy? Readers of The Niche have regularly asked this question. They’re curious about insurance coverage too. The answer is “no” in almost every case, with some notable exceptions I’ll get to at the end of the post. Still, clinics appear to have already been charging Medicare for what collectively adds

3rd Invitrx warning highlights FDA oversight weakness

The FDA seems oddly slow in oversight of unproven stem cell clinic-related firms like one here in California called Invitrx Therapeutics. I’ve written before about Invitrx, but interactions between them and the FDA have continued including a new warning letter. It’s become a puzzling situation. More broadly, the FDA has done relatively little in the past

Review of ExoFlo paper used to push Direct Biologics IND inside FDA finds red flags

ExoFlo from Direct Biologics

I wrote recently about how political pressure on FDA Commissioner Stephen Hahn in 2020 may have helped the Texas firm Direct Biologics move their product ExoFlo forward inside the agency. Today I analyze the ExoFlo Phase I clinical trial paper used in that push on Hahn to get the firm the IND for a Phase II
