OS is the time between the first day of treatment to the day of disease progression. Progressive disease is assessed by the International Workshop to Standardize Response Criteria for Non-Hodgkin's Lymphoma, and is the appearance of new lesions, or an increase of 50% or greater in the sum of the product of the perpendicular diameters of the measurable lesions or persistent (at least two determinations) doubling of the peripheral blood leukemic cell count.

Here is the number of participants with serious and non-serious adverse events assessed by the Common Terminology Criteria in Adverse Events (CTCAE v4.0). A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned.

DLT is a grade II-IV LMB-2 or fludarabine and cyclophosphamide (FC)-related toxicity, except vascular leak syndrome, alopecia, grade II-III allergic reaction with asymptomatic bronchospasm or urticarial is considered DLT. Grade III aspartate aminotransferase, alanine aminotransferase, gamma glutamyl transferase, and fever are not considered DLT. Grade IV creatine phosphokinase associated with any other DLT or not resolving to \

Tumor tissue, including lymph node or skin biopsies was examined and analysis performed by flow cytometry to determine the amount of cancer cells in the body by measuring proteins which fall off cancer cells and go into the blood.

AUC is a measure of the plasma concentration of drug over time. It is used to characterize drug absorption. Plasma levels were analyzed by cytotoxicity assay.

Peripheral blood was obtained and analyzed by flow cytometry.

Blood was drawn prior to each cycle of LMB-2 to determine if the level, >75% neutralization of 1000ng/ml of LMB-2 of neutralizing antibodies is too high to give additional LMB-2. Analysis was performed by cytotoxicity assay.

Duration of response is defined as a response lasting for at least 4 weeks but >8 weeks and is assessed by the International Workshop to Standardize Response Criteria for Non-Hodgkin's Lymphoma. Complete remission (CR) is complete disappearance of all detectable clinical and radiographic evidence of disease and disappearance of all disease related symptoms if present before therapy and normalization of those biochemical abnormalities definitely assignable to the lymphoma. Partial response is reduction by ≥50% of leukemia cell count or ≥50% reduction in the size of all measurable lesions, and no increase in size of any measurable or evaluable lesion or appearance of new lesion.

Dilutions of patient plasma was tested by cytotoxicity assays to determine plasma clearance of LMB-2.The CL is a quantitative measure of the rate at which a drug substance is removed from the body.

Dilutions of patient plasma were tested by cytotoxicity assays to determine volume of distribution of LMB-2. Volume distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug. This was measured during the first 24 hours after administration of the dose on cycle 2 day 1.

Dilutions of patient plasma was tested by cytotoxicity assays to determine half life. Plasma decay half-life is the time measured for the plasma concentration of the drug to decrease by one half.

Adverse events is assessed by the Common Terminology Criteria in Adverse Events (CTCAE v4.0). A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned. Grade 3 (mild), Grade 4 (life threatening) and Grade 5 (death).

PFS was determined by the Kaplan Meier method beginning at the on study date and continuing until progression or last follow-up without progression. Progressive disease is assessed by the International Workshop to Standardize Response Criteria for Non-Hodgkin's Lymphoma, and is the appearance of new lesions, or an increase of 50% or greater in the sum of the product of the perpendicular diameters of the measurable lesions or persistent (at least two determinations) doubling of the peripheral blood leukemic cell count.
