An analyst asked Amgen management about SC Tepezza about 29 minutes in the Acquisition of Horizon conference call. They did not mention Halo and their answer was a little vague (they said they were unable to answer a lot of questions because the acquisition will complete in first half of 2023) but they said they have a lot of expertise in drug delivery and they are definitely interested in SC formulations. It wasn't clear to me how committed they are to Enhanze but they were probably vague because of the above and for competitive reasons.
