Inclusion Criteria

• Previously participated in prior clinical study CC-93538-EE-001 and either:
- completed both the Induction and Maintenance phases; or
- completed the Induction Phase, however, did not qualify for the Maintenance Phase, including having a severe EoE flare requiring endoscopic intervention or rescue therapy.
•OR Subject must have participated in Study CC-93538-DDI-001 and completed assessments in Period 2 through Week 18/End of Treatment Visit.
• Demonstrated compliance with required investigational product dosing during the prior Study CC-93538-EE-001 or Study CC-93538-DDI-
001.
• Did not permanently discontinue investigational product in the prior Study CC-93538-EE-001 or Study CC-93538-DDI-001 and/or did not experience any clinically significant adverse events related to Investigational Product that would preclude further dosing.
• Females of childbearing potential must have a negative pregnancy test prior to the first dose of open-label CC-93538 and agree to practice a highly effective method of contraception (as defined in the prior study) until 5 months after the last dose of open-label CC-93538.
• Subject (18 years of age or older) must understand and voluntarily sign an informed consent form (ICF) prior to any study-related assessments/procedures being conducted. For subjects less than 18 years of age, subject assent must be obtained, and parental/legal representative consent is required. Adolescent subjects who reach the legal age of consent while participating in the study will be asked to sign an ICF (called a Transitional ICF) themselves to acknowledge their willingness to continue in the study. In Austria, Germany, Spain, and Switzerland, adolescent subjects will not be enrolled.

Exclusion Criteria

• Clinical or endoscopic evidence of other diseases or conditions that may affect or confound the histologic, endoscopic, or clinical symptom evaluation for this study.
• Active Helicobacter pylori infection or esophageal varices.
• Evidence of immunosuppression, or of having received systemic immunosuppressive or immunomodulating drugs within 5 drug half-lives prior to open-label extension study (OLE) Day 1. Use of these agents is prohibited during the study.
• Treatment with oral or sublingual immunotherapy within 6 months of OLE Day 1. Use of these agents is prohibited during the study.
• Received an investigational product, other than that administered in CC-93538-EE-001 or Study CC-93538-DDI-001, within 5 half-lives prior to OLE Day 1 (includes investigational product received during an interventional trial for COVID-19). Those vaccinated with an investigational COVID-19 vaccine during CC-93538-EE-001 or Study CC-93538-DDI-001 are not eligible, unless allowed following a discussion with the Clinical Trial Physician.

• Any disease that would affect the conduct of the protocol or interpretation of the study results, or would put a patient at risk by participating in the study (e.g. colitis, celiac disease, Mendelian disorder associated with EoE, severe uncontrolled asthma, infection causing eosinophilia, hypereosinophilic syndrome, a documented medical
diagnosis of gastritis, which is clinically significant in the judgment of the Investigator or cardiovascular condition, or neurologic or psychiatric illness that could compromise the subject's ability to accurately document symptoms of EoE; newly diagnosed malignancy, lymphoproliferative disease, or clinically significant laboratory abnormality).
• Active or ongoing infections including parasitic/helminthic infections, viral hepatitis, tuberculosis, or HIV.
