M118 uses the heparinases and purifies active fractions or better yet once they know the active fractions they chemically synthesize them. Better activity and pharmacokinetics than Lovenox. I can see from the PNAS paper why interest in high in this version.
Versus M-Enoxaparin which uses chemical synthesis and chemical cleavage to produce a Lovenox equivalent. Two other ANDAs outstanding. All are likely to require immunogenicity data to get FDA approval.
Was MNTA furthest along in the FDA process of the three generics?
