SUMMARY

  • Sumitomo Pharma targets 350 billion JPY in iPs revenue, including from Amchepry

  • The Center for iPS Cell Research & Application (CiRA) is SP’s research partner

  • CIRA is IPS cells supplier for the Amchepry trials, conducts the trials + research

  • CiRA is paid by Sumitomo Pharma, with a relationship since 2011.

  • Sumitomo Pharma is going all-in on CiRA while Takeda recently terminated its 10 year partnership with CiRA.

  • There are two well documented cases of fraud involving CiRa and its founder Shinya Yamanaka, in 2014 and 2018.

  • However, we have discovered 8 additional problematic cases, including 1 research paper where the Amchepry trial’s lead investigator is an author

  • Amchepry depends on the integrity of CiRA, but CiRa is suspect, unreliable.

Registration is usually easier when the instructions are clearly presented and users know what information they need beforehand. If someone is researching RaxiWin Register, checking the official-looking page details and account requirements should be the starting point. The RaxiWin Register term is specific enough to narrow the search, but it is still worth confirming that the result contains the registration information being sought.

Insightful investigative piece! This post draws important links between commercial regenerative‑medicine ambitions at Sumitomo Pharma and outstanding research‑integrity questions surrounding CiRA. It brings forward under‑discussed concerns that deserve attention from investors and the broader biotech community. Great job assembling and summarizing this complex material for public readers.  --bike bros
