Time frame
Prior to enrollment during screening, and for participants still having malignant cells, the test was to be repeated prior to each cycle of therapy, at the end of treatment, and end of the study (approximately 8 years)

What was measured

Participants malignant cells (paraffin block biopsy specimen) were tested for CD22 expression by FACS analysis.

Analysis population: Safety population included all participants who received any treatment of moxetumomab pasudotox.

Groups in this outcome

5 mcg/kg

Participants received IV 5 mcg/kg moxetumomab pasudotox on Days 1, 3, and 5 of every 28-day cycle and continued until complete response (CR), progressive disease (PD), initiation of alternative anticancer therapy, unacceptable toxicity, development of neutralizing antibodies, or another reason to discontinue therapy.

10 mcg/kg

Participants received IV 10 mcg/kg moxetumomab pasudotox on Days 1, 3, and 5 of every 28-day cycle and continued cycles of therapy until CR, PD, initiation of alternative anticancer therapy, unacceptable toxicity, development of neutralizing antibodies, or another reason to discontinue therapy.

20 mcg/kg

Participants received IV 20 mcg/kg moxetumomab pasudotox on Days 1, 3, and 5 of every 28-day cycle and continued cycles of therapy until CR, PD, initiation of alternative anticancer therapy, unacceptable toxicity, development of neutralizing antibodies, or another reason to discontinue therapy.

30 mcg/kg

Participants received IV 30 mcg/kg moxetumomab pasudotox on Days 1, 3, and 5 of every 28-day cycle and continued cycles of therapy until CR, PD, initiation of alternative anticancer therapy, unacceptable toxicity, development of neutralizing antibodies, or another reason to discontinue therapy.

40 mcg/kg

Participants received IV 40 mcg/kg moxetumomab pasudotox on Days 1, 3, and 5 of every 28-day cycle and continued cycles of therapy until CR, PD, initiation of alternative anticancer therapy, unacceptable toxicity, development of neutralizing antibodies, or another reason to discontinue therapy.

50 mcg/kg

Participants received IV 50 mcg/kg moxetumomab pasudotox on Days 1, 3, and 5 of every 28-day cycle and continued cycles of therapy until CR, PD, initiation of alternative anticancer therapy, unacceptable toxicity, development of neutralizing antibodies, or another reason to discontinue therapy.
