I haven't listened to the cc, my opinion is entirely based on second hand reading here and there.
I think they probably over compensated for injection site comfort, it adversely affected efficacy. The key question is whether they can create PH neutral formula that retains same efficacy. I thought they could. Now obviously you can go back and question whether they should have tested not as similarly formulated as 105 and 107 to answer this question. I don't know the answer, I don't think they know either at this point.
As of making existing analog UFI, I don't have any data from them as basis to have an opinion. So I don't know. The approach is similar to HALO now, and they are well behind HALO, so it really depends on how HALO's version does at this point. We should know by the end of this qtr.
