How is Novo Nordisk preparing for NovoSeven patent expiration?

[Updated for NN7128 completion of phase-1.]


NVO’s blockbuster rFVIIa drug, NovoSeven, goes off-patent in the US—its largest market—in 2011. NVO has a two-pronged approach to deal with this predicament:

1. A fast-acting FVIIa analog called NN1731, which is in phase-2:

2. A long-acting FVIIa analog called NN7128 based on pegylation technology from NTEC, which has completed phase-1 (#msg-29710045).

Clearly, both of these programs warrant close attention by GTC investors. However, these two drug candidates are FVIIa analogs, not FVIIa per se. Thus, they would seem to incur a higher regulatory risk than the FVIIa program from GTC and LFB.
