Citi analyst Mohit Bansal recommends using today's selloff in shares of Coherus Biosciences (CHRS) as a buying opportunity. Checks with patent experts indicate that the patent in today's case is not a key obstacle against a biosimilar of AbbVie's Humira, Bansal tells investors in a research note. Further, the analyst estimates fair value of Coherus shares at $24 if the Humira biosimilar is removed completely. The stock is currently down 16%, or $4.60, to $23.55. Basel does not expect a biosimilar launch until 2020. He adds that every one year launch delay post 2020 would impact his fair value for shares by only $1. The analyst keeps a Buy rating on Coherus with a $36 price target.

AbbVie announced positive top-line results from SELECT-GCA, a Phase 3, multicenter, randomized, double-blind, placebo-controlled study, showing upadacitinib in combination with a 26-week steroid taper regimen achieved its primary endpoint of sustained remissiona from week 12 through week 52 in adults with giant cell arteritis. In this study, 46% of patients receiving upadacitinib 15 mg in combination with a 26-week steroid taper regimen achieved sustained remission compared to 29 percent of patients receiving placebo in combination with a 52-week steroid taper regimen. Key secondary endpoints were also met, including a higher percentage of patients receiving upadacitinib 15 mg in combination with a 26-week steroid taper regimen achieved sustained complete remissionb from week 12 through week 52 compared to patients receiving placebo in combination with a 52-week steroid taper regimen. A lower percentage of patients experienced at least one disease flare through week 52 in the upadacitinib 15 mg group versus the placebo group. The study results also showed that upadacitinib 7.5 mg did not meet the primary or any of the secondary endpoints.
