• A pivotal Phase 3 study is planned for 2018 evaluating the use of dupilumab in eosinophilic esophagitis (EoE), a condition for which there are no approved therapies in the U.S.
• Phase 2 studies investigating the use of dupilumab as an adjunctive therapy to immunotherapies for the treatment of peanut and grass allergy are planned for 2018.
• Dupilumab studies are planned for 2018 to evaluate patients with comorbid allergic inflammatory conditions.
• REGN3500, an antibody to IL-33, is currently being investigated in Phase 1b studies in adult patients with moderate asthma and mild allergic asthma both as monotherapy and in combination with dupilumab.
• In 2018, the companies plan to initiate Phase 2 proof-of-concept studies for REGN3500 in asthma and COPD, and a Phase 2b study in atopic dermatitis.

• Cemiplimab in combination with ipilimumab or chemotherapy in patients with PD-L1 expression greater than or equal to 50 percent (planned).
• A second-line study of cemiplimab in NSCLC is also planned.
• Regeneron is also advancing REGN3767, a LAG3 antibody, for cancer both as monotherapy and in combination with cemiplimab, as well as other preclinical immuno-oncology bispecific and monoclonal antibody therapies.
