I have to admit that I'm still a bit confused.

I guess this new trial can be seen as bullish, because Al mentions that this 30 U cartridge would need approval AFTER the 10 U and 20 U cartridges are approved. The company is of course beginning the 30 U trial, which could mean it believes the 10 U and 20 U cartridges are likely to get approved and the 30 U trial is merely the next order of business.

That said, will the 30 U cartridge eventally replace the 10 U + 20 U cartridges or is the 30 U cartridge being made for people who need more insulin (i.e. 30 U + 20 U = 50 U)? Again, I'm admittedly lost in this perspective.
