What was measured

Dose limiting toxicity (DLT) is defined as all treatment related Grade 3-5 adverse events (AEs) occurring from the initiation of moxetumomab pasudotox-tdfk therapy to within 30 days after the last dose of moxetumomab pasudotox-tdfk treatment. Adverse events were assessed by the Common Terminology Criteria for Adverse Events (CTCAE v5.0). Grade 3 is severe, Grade 4 is life-threatening, and Grade 5 is death related to adverse event.

Groups in this outcome

Moxetumomab - Dose Escalation 30 mcg/kg

Participants with Relapsed/Refractory Hairy Cell Leukemia (HCL) or Hairy Cell Leukemia (HCLv) Arm 1 Moxetumomab Pasudotox-tdfk + Rituximab Dose escalation treatment with moxetumomab -pasudotox-tdfk and rituximab Moxetumomab pasudotox-tdfk is administered at 30 ug/Kg intravenous (iv) over 30 min given on days 1, 3, 5 of each cycle. Rituximab will be administered at 375mg/m\^2 iv, 50-400 mg/hour (hr). On cycle 1, Rituximab is given on day -2, on subsequent cycles, Rituximab is given on day 1.

Moxetumomab - Dose Expansion 40 mcg/kg

Dose expansion; treatment with moxetumomab -pasudotox-tdfk and Ruxience Arm 1 and Arm 2 Moxetumomab Pasudotox-tdfk + Ruxience Moxetumomab pasudotox-tdfk is administered at 40 ug/Kg intravenous (iv) over 30 min given on days 1, 3, 5 of each cycle. Ruxience will be administered at 375mg/m\^2 iv, 50-400 mg/hour (hr). On cycle 1, Ruxience is given on day -2, on subsequent cycles, Ruxience is given on day 1 (Delta)
