- Score 5: Hospitalized, requiring supplemental oxygen
- Score 6: Hospitalized, on non-invasive ventilation or high-flow oxygen device
- Contraceptive use by men and women of childbearing potential consistent with local regulations regarding the methods of contraception for those participating in clinical studies and according to Appendix 3 in the Protocol (see Section 10.3)
