2. Demonstrated compliance with required investigational product dosing during the prior Study CC-93538-EE-001 or Study CC-93538-DDI001 and subject must not have been permanently discontinued from IP while participating in Study CC-93538-EE-001 or Study CC-93538-DDI-001.
3. Subjects must have not experienced any clinically significant adverse events related to Investigational Product that would preclude further dosing.
4. Females of childbearing potential must have a negative pregnancy test prior to the first dose of open-label CC-93538 and agree to practice

5. 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

5. Treatment with oral or sublingual immunotherapy within 6 months of OLE Day 1. Use of these agents is prohibited during the study.
6. 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).
