The dose must remain stable (Subjects on these treatments must be willing to remain on a stable dose for the specified duration) for the first 10 weeks after randomization.
11. Patients willing to abstain from receiving live o r attenuated vaccines throughout the study and for 12 weeks after the last dose.

Exclusion Criteria

1. Pregnant or lactating women
2. Those who wish to become pregnant within the next year
3. Women who are planning to donate eggs or collect eggs for the purpose of fertilization for the present or future during this study period or within 35 days after the last dose of the clinical study drug
4. Men who are not willing to refrain from sperm donation for at least 90 days after the last dose of the clinical study drug
5. Known hypersensitivity to the excipients of the FIL/AZA, its metabolites, or formulation
