Nausea, vomiting and diarrhea will only be considered a DLT if it cannot be adequately managed with optimal supportive care. Grade 3 or 4 hyperglycemia due to dexamethasone will only be considered a DLT if it cannot be controlled with appropriate therapy Grade 4 hematologic toxicity, with the following exceptions: Grade 4 lymphopenia is expected with this regimen and will not be construed as a DLT. Grade 4 neutropenia will only be considered a DLT if it lasts longer than 7 days despite appropriate supportive care. Grade 4 thrombocytopenia will only be considered a DLT if it lasts longer than 7 days or is associated with greater then or equal to grade 3 bleeding event","groups":[{"description":"A 3 + 3 phase I dose escalation design was used to examine the safety profile and establish the MTD of IXA when given in combination with POM-DEX.
