However, for subjects with bulky disease,systemic symptoms, compressive disease, or rapidly progressing adenopathies, pre-phase treatment with 1 mg/kg/day prednisone, or equivalent, for a maximum of 7 days is permitted prior to Cycle 1 Day -6 at the discretion of the Investigator. In exceptional cases, if clinically indicated, a higher dose of steroids and/or a slightly longer duration is allowed for the purpose of urgent symptom management, and the subjects is considered eligible. A washout period does not apply. However the fresh core biopsy mentioned above should be performed before starting prednisone.
