Stifel analyst Derek Archila views Selecta Biosciences (SELB) SEL-212 Phase 2 data in chronic severe gout as positive and thinks it represents a "very competitive" emerging profile relative to the incumbent brand, Horizon Pharma's (HZNP) Krystexxa. The analyst comes away positive with the fact SEL-212's projected response rate remains competitive on a modified intent-to-treat basis, SVP-Rapamycin was tolerable out to five months of dosing, and SEL-212's rate of gout flares was lower than Krystexxa alone and Krystexxa+methotrexate early on. Archila remains positive on the stock and believes SEL-212 could offer an improvement to the current standard of care for chronic severe gout. Further, Archila does not believe shares fully reflect the program's commercial potential and reiterates a Buy rating on Selecta's shares.
