Connect Biopharma Holdings Limited announced that the first subject has been dosed in a Phase 2 trial evaluating CBP-201 in adult patients with chronic rhinosinusitis with nasal polyps (CRSwNP). This multi-center, randomized, double-blind, placebo-controlled trial was designed to evaluate the effect of CBP-201 administered as a subcutaneous injection (“SC”) on a background of mometasone furoate nasal spray (“MFNS)” in reducing endoscopic nasal polyp score (“NPS”) and nasal congestion/obstruction score (“NCS”) severity in eligible patients with CRSwNP whose disease remains inadequately controlled despite daily treatment with intranasal corticosteroid (“INCS”) therapy in comparison to placebo. The trial is dividend into a treatment period of 24 weeks and a follow-up period of 8 weeks and is expected to enroll approximately 140 patients with CRSwNP across approximately 60 clinical sites in the United States, China, European Union and Eurasian Economic Union (NCT04783389).
