According to the Complaint, the Company made false and misleading statements to the market. Mereo concealed negative facts about its Phase 3 ORBIT and COSMIC programs. The Company later revealed neither program hit its primary endpoint. Based on these facts, the Company's public statements were false and materially misleading throughout the class period. When the market learned the truth about Mereo, investors suffered damages.
