News from the trachea transplant entrepreneurs. What with the UK authorities having officially suspended both phase 1 clinical trials Inspire and RegenVox, and the EU phase 2 clinical trial TETRA going nowhere, the technology’s owner, Liverpool-based company Videregen decided to seek new clinical partners. Surgeons and universities from outside the EU, especially from US, China and Japan are invited to test Videregen’s trachea transplant technology, which was originally developed together with Paolo Macchiarini by the UCL laryngologist and paid Videregen advisor Martin Birchall.
While tracheal stenosis was the indication sought to treat with trachea transplants in UK and EU (as the authorities drew curtains before the show even started), Videregen now goes for bronchopleural fistula, while pretending (quite dishonestly) that “all required regulatory and ethical approvals necessary to commence clinical trials in the UK” would exist.
The other bit of news is that UCL finally published the 2015 PhD thesis of Birchall’s student Claire Crowley (now postdoctoral scientist in charge of clinical research on oesophagus replacement with UCL professor and another trachea transplanter Paolo De Coppi). It reads as if certain parts of the thesis were edited or even written by UCL’s legal department. Not what thesis says, but what is omitted is worrisome. Crowley was namely responsible for the production of 3 trachea replacements requested by Birchall, which all proved deadly to their human recipients. One was a decellurised cadaveric graft, and two were POSS-PCU plastic tracheas, which Crowley made herself, in the lab of her other advisor, the (now sacked) UCL nanotechnologist Alexander Seifalian. Yet the thesis only mentions one graft, in a brief one-page statement, simply because Crowley could not deny her role there. She is co-author on the Macchiarini paper Jungebluth et al Lancet 2011 telling the alleged success story of the very first plastic trachea transplant performed in Sweden on the patient Andemariam Beyene. Otherwise, Crowley never mentions in her thesis the cases of Keziah Shorten or Shauna Davison, whose lethal trachea grafts she also made herself, as part of her PhD studies.
