If Sandoz is estimating it will generate $40 mil in sales over the next 6 weeks that would mean Sandoz is estimating it will capture around 16.1% of the normal lovenox market in it's 1st quarter.
Even in 2010 mL is expected to be Sandoz biggest selling drug; and this is a statement about sales over the next 6 weeks.
That gives us some idea of part of the cost that MNTA will have to repay. I would assume that "developing" does not include legal costs but I cannot sure.
