Maximum Tolerated Dose (MTD) of Inotuzumab Ozogamicin in Combination With Rituximab (375 mg/m^2 )Primary· First 28-day cycle
Inotuzumab ozogamicin was dose escalated (3 to 6 evaluable participants enrolled per dose cohort) during the first 28 days after the first administration of inotuzumab ozogamicin + rituximab. Enrollment at the next dose level or enrollment of additional subjects into a cohort proceeded according to the following criteria: 0 dose-limiting toxicity (DLT) by Day 28 of first dose move to higher dose, 1 participant reporting DLT but no others in cohort by Day 28 of first dose move to higher dose, greater than 2 participants reporting DLT by Day 28 of first dose stop and prior dose level considered

This outcome measure time frame: From the first dose of study drug to up to 56 days after the last dose of either study drug.
A TEAE is any event that occurred after the first dose of study drug up to 56 days post the last dose of study drug (either rituximab or inotuzumab ozogamicin).
Percentage of Participants With Complete Response (CR), Unconfirmed CR (CRu), or Partial Response (PR)Secondary· Approximately every 2 (during treatment) or 3 (during follow-up) to 6 months for up to 5 years from 1st dose
CR: a. Complete disappearance of all detectable clinical and radiographic evidence of disease, disease-related symptoms, and normalization of NHL assignable biochemical abnormalities ; b. lymph nodes and nodal masses must have regressed to normal size; c. Spleen regressed in size and not palpable on physical exam, size of other organs enlarged due to disease decreased in size; d. Repeat bone marrow infiltrate clear. CRu: CR but allows for a.

Kaplan-Meier Estimates of Progression Free Survival (PFS)Secondary· From the date of first dose of test article until the first date on which disease progression or death was documented or new anticancer start, any of which could be reported up to 5 years post last dose
The Kaplan-Meier method was used to determine PFS. 95% 2-sided confidence interval were calculated using stratified Cox proportional hazard regression. Relapsed or Progressive Disease (PD) requires the following: a. Appearance of any new lesions, b. Increase by \>= 50% in the size of previously involved sites, c. \>= 50% increase in greatest diameter of any previously identified node greater than 1 cm in its short axis or in the SPD of more than one node, d. \>= 50% increase from nadir in the product diameter of any previously identified abnormal node for PRs or nonresponders, e.

Kaplan-Meier Estimates of the Probability of Being Progression Free at 6 MonthsSecondary· From the first dose to 6 months after first dose
Progression Free Survival is defined as the time interval from the first dose of test article until the first date on which relapsed disease, progression, initiation of new anti-cancer treatment due to persistent/refractory disease, or death was documented, censored at the last tumor evaluation.
Kaplan-Meier Estimates of Overall Survival (OS)Secondary· From the first dose up to 5 years post last dose
OS was defined as the time from randomization to death due to any cause, censoring at the date of last contact. The Kaplan-Meier method was used to determine OS. 95% 2-sided confidence interval were calculated using stratified Cox proportional hazard regression.

Duration of Response (CR+CRu+PR)Secondary· Time from date measurement criteria are met for CR, CRu, or PR (whichever status is recorded first) until the first date relapsed disease or date of death (whichever occurs first) is objectively documented.
Time from date measurement criteria met for CR, CRu, or PR (whichever occurred first) until first date relapsed disease/date of death. CR: Complete disappearance of all detectable clinical, radiographic evidence of disease, disease-related symptoms, normalization of NHL assignable biochemical abnormalities; lymph nodes, nodal masses regressed to normal size; spleen size regressed, not palpable on physical exam, size of other organs enlarged due to disease.

Serum concentration of inotuzumab ozogamicin on Dosing Days 30 and 58 were measured. AUCinf of inotuzumab ozogamicin was reported. AUCinf: AUClast (area under the serum concentration-time profile for inotuzumab ozogamicin from time zero to the time of the last quantifiable concentration) +(Clast \[last quantifiable concentration\]/kel \[elimination rate constant\]) where Clast is the predicted serum concentration of inotuzumab ozogamicin at the last quantifiable timepoint estimated from the log-linear regression analysis.

Adverse events — posted to ClinicalTrials.gov
Time frame: Adverse events were recorded and reported from the time a participant signed the Informed Consent Form (ICF) until at least 28 days after last dose of study treatment. Summarized data reflects incidents from 1st dose to up to 56 days post last dose..
Reporting threshold: 5%.
Adverse-event reports describe events observed during the trial — not all are caused by the drug.
The purpose of the study is to determine the tolerability, the initial safety profile and maximum tolerated dose, and to obtain preliminary information on the antitumor activity of inotuzumab ozogamicin \[CMC-544\] in combination with rituximab in subjects with follicular, diffuse large B-Cell, or mantle cell NHL.
