Thanks for posting this! The data seems very good.From what I understood (I'm a mechanical engineer, so my understanding of chemistry is limited), it seems like they were trialing it in combination with and independently of the Tetrandrine to see what it would do. It's a long read. Interestingly, the patent expiration was extended.

There have been many companies that have failed in this space but, given the people behind this + their backgrounds, it inspires a bit of confidence and hope. Let's see how the clinical trials go.
