(Nasdaq: ANAB), a clinical-stage biotechnology company developing first-in-class antibody product candidates focused on emerging immune control mechanisms applicable to inflammation and immune-oncology indications, today reported top-line data from a week 8 interim analysis of the Company’s ongoing ECLIPSE Phase 2 clinical trial of etokimab, an anti-interleukin-33 (IL-33) monoclonal antibody, in patients with chronic rhinosinusitis with nasal polyps (CRSwNP). \n Patients dosed with etokimab every four (q4w) or eight weeks (q8w) failed to achieve statistically significant improvement in their bilateral nasal polyps score (NPS), an endoscopic measure of nasal occlusion, and in their sino-nasal outcome test (SNOT-22), a patient reported quality-of-life assessment, versus placebo at the week 8 timepoint. Both endpoints demonstrated statistically significant improvement over baseline levels of NPS and SNOT-22. Blood eosinophil levels, which are a biomarker of etokimab’s mechanism, demonstrated statistically significant reduction relative to baseline in both etokimab treatment arms. The Company intends to determine next steps for the etokimab program after reviewing week 16 primary endpoint by year-end 2020. “We are disappointed that etokimab did not demonstrate significance over placebo in either treatment arm in this week 8 interim analysis,” said Hamza Suria, president and chief executive officer of AnaptysBio. “We plan to re-assess the etokimab program following review of the complete week 16 data from the ECLIPSE trial later this year.” ECLIPSE Trial DesignThis Phase 2 trial enrolled 105 adult chronic rhi...
