I thought Hospira was a relatively serious company; why do they sacrifice their credibility on this program? It's not like they are subject to Zebra's Law.
HSP presumably licensed the vial formulation of a Lovenox knockoff from a foreign company and submitted the specs to the FDA. They did not seriously expect FDA approval, IMO, but they had almost nothing to lose by trying. It probably would have taken more work than HSP thought the project was worth to amend the formulation for prefilled syringes.
