     * Relapse of the initial disease after a period of achieving complete remission.
3. Subject can swallow and retain oral medication and does not have uncontrolled emesis or persistent diarrhea.
4. Adequate renal, hematological, and hepatic function at the investigator's discretion.
5. Without uncontrolled or significant comorbidities determined by clinical history, physical examination, and screening laboratories at the investigator's discretion.
