What was measured

A classic 3+3 dose-escalation design was used to assess the MTD of siplizumab in combination with dose-adjusted etoposide, prednisone, vincristine, cyclophosphamide, doxorubicin and rituximab (EPOCH-R). If 2 of 6 patients experienced a dose-limiting toxicity (DLT) at a particular dose level, the MTD has been exceeded. The preceding dose level will be the MTD, provided 6 patients have been entered at this level and no more than one has experienced a DLT. DLTs for siplizumab was defined as infusional grade 3 non-hematologic toxicity lasting longer than 6 hours after the infusion, any grade 4 non-hematologic toxicity, or the development of an Epstein Barr Virus (EBV)-related lymphoproliferative disorder (LPD). Expected toxicities of dose-adjusted EPOCH-R and grade 3 laboratory adverse events (AEs) were not considered to be DLTs.

Groups in this outcome
