What is being measured
The primary outcome is the main question the study is designed to answer.
Maximum Tolerated Dose (MTD) of Inotuzumab Ozogamicin in Combination With Rituximab (375 mg/m^2 )
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 MTD. The worldwide medical monitor and investigators reviewed all significant study drug-related toxicities to determine if the dose escalation rules were satisfied and whether the dose escalation schedule required modification.
Measured: First 28-day cycle
Percentage of Participants With a Treatment Emergent Adverse Event (TEAE) (Safety Population)
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).
Measured: Protocol reporting period of from informed consent to at least 28 days after the last dose. 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.
Secondary outcomes (48)

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. Residual lymph node mass >1.5 cm in greatest transverse diameter has regressed by more than 75% in diameter. Individual nodes that were previously confluent regressed more than 75 % in their product diameters; b. Indeterminate bone marrow.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.

Primary outcome
Maximum Tolerated Dose (MTD) of Inotuzumab Ozogamicin in Combination With Rituximab (375 mg/m^2 )
Time frame: 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 MTD. The worldwide medical monitor and investigators reviewed all significant study drug-related toxicities to determine if the dose escalation rules were satisfied and whether the dose escalation schedule required modification.
Percentage of Participants With a Treatment Emergent Adverse Event (TEAE) (Safety Population)
Time frame: Protocol reporting period of from informed consent to at least 28 days after the last dose. 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).
48 secondary outcomes

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing inotuzumab ozogamicin and Rituximab in people with B-Cell Lymphoma, run by Pfizer at 38 sites in 13 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 8 Mar 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 38 sites in United States, Belgium, France, United Kingdom, Germany and 8 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 8 Mar 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Maximum Tolerated Dose (MTD) of Inotuzumab Ozogamicin in Combination With Rituximab (375 mg/m^2 ) (time frame: First 28-day cycle). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00299494, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Mar 2018.
