What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
BendamustineDrug
| Study group | Role | What they receive |
|---|---|---|
| Bendamustine | Experimental | Bendamustine 90 or 120 mg/m^2 administered as an intravenous (IV) infusion over 60 minutes on Days 1 and 2 of each 21-day cycle (maximum of 12 total cycles), with delays up to 2 weeks for neutrophil and platelet count recovery, for up to a 35-day cycle. Receives: Drug: Bendamustine |
What is being measured
The primary outcome is the main question the study is designed to answer.
Recommended Phase II Dose (RP2D) of Bendamustine
RP2D was determined by a traditional 3+3 dose escalation design, with the following restrictions: only doses of 60, 90, 120, and 150 mg/m^2 were explored, and escalation to 150 mg/m^2 would only occur if the 120 mg/m^2 dose was deemed safe and pharmacokinetic data indicate subtherapeutic exposure as compared with adults. The first cohort was administered bendamustine at the 90 mg/m^2 dose; de-escalation to the 60 mg/m^2 dose would only occur if the starting dose led to dose-limiting toxicity (DLT) in 2 or more participants. A DLT was defined as any study drug-related nonhematologic adverse event (AE) that was grade 4 for toxicity by National Cancer Institute's Common Toxicity Criteria for AEs, version 4. In addition, grade 3 or above allergic reaction or skin rash were considered DLTs. Hematologic AEs were not considered DLTs. The dose level at which at least 2 of 3 or 2 of 6 participants had a DLT was considered as exceeding the RP2D. The RP2D was the dose 1 step below that level.
Measured: Induction Cycle (21- to 35-day cycle)
Overall Response Rate (ORR)
ORR was calculated as follows: number of participants in the primary analysis set achieving a best overall response of complete remission without platelet recovery (CRp) or complete remission (CR), divided by the number of participants in the primary analysis set. The most positive response for each patient during the study was counted. The 95% CI was calculated using binomial parameter exact method. Response was determined by the investigator, and evaluated per Jeha et al, 2006: A CR required no evidence of circulating blasts or extramedullary disease, an M1 marrow (≤ 5% bone marrow blasts), and recovery of peripheral counts (platelets ≥ 100 × 10^9/L and absolute neutrophil count ≥ 1.0 × 10^9/L). A CR without platelet recovery (CRp) required all of the criteria for a CR with the exception of platelet recovery.
Measured: Assessed at each treatment cycle (21 to 35 days), for a maximum of 12 cycles
Secondary outcomes (7)
Best Overall Tumor Response Rate
Biological activity of bendamustine was defined as achieving a best response of partial response (PR), CRp, or CR. Rate was calculated as follows: number of participants in the primary analysis set achieving a best overall response of PR, CRp, or CR, divided by the number of participants in the primary analysis set. The most positive response for each patient during the study was counted. The 95% CI was calculated using binomial parameter exact method. Response was determined by the investigator, and evaluated per Jeha et al, 2006: A PR had to meet the following criteria: complete disappearance of circulating blasts and an M2 marrow (≥ 5% and ≤ 25% bone marrow blasts) and appearance of normal progenitor cells or an M1 marrow that did not qualify for CR or CRp. See Outcome Measure 2 for full definitions for CRp and CR.
Measured: At each treatment cycle (21 to 35 days), for a maximum of 12 cycles
Best Overall Tumor Response Rate, by Phase
Biological activity of bendamustine was defined as achieving a best response of partial response (PR), CRp, or CR. Rate was calculated as follows: number of participants in the primary analysis set achieving a best overall response of PR, CRp, or CR, divided by the number of participants in the primary analysis set. The most positive response for each patient during the study was counted. The 95% CI was calculated using binomial parameter exact method. Response was determined by the investigator, and evaluated per Jeha et al, 2006: A PR had to meet the following criteria: complete disappearance of circulating blasts and an M2 marrow (≥ 5% and ≤ 25% bone marrow blasts) and appearance of normal progenitor cells or an M1 marrow that did not qualify for CR or CRp. See Outcome Measure 2 for full definitions for CRp and CR.
Measured: At each treatment cycle (21 to 35 days), for a maximum of 12 cycles
Duration of Response (DOR)
DOR was determined for the participants with CR or CRp in the primary analysis set, defined as the time from first achieving remission to the time when progression was diagnosed, the participant died, or the participant started receiving new antineoplastic therapy. Data from participants who do not progress were censored at the last valid assessments. Median DOR and its 95% confidence interval was determined based on the Kaplan-Meier method. Data from participants who received a transplant were censored at the time of the transplant.
Measured: At each treatment cycle (21 to 35 days), for a maximum of 12 cycles
Maximum Observed Plasma Drug Concentration (Cmax) for Bendamustine and Its Metabolites (M3 and M4)
Measured: Cycle 1, Day 1: before infusion, immediately following the infusion, and 3, 6, 10(±2), and 24 hours after the start of infusion. The 24-hour postinfusion sample was obtained before the start of the infusion on Day 2.
Time to Maximum Plasma Drug Concentration (Tmax) for Bendamustine and Its Metabolites (M3 and M4)
Measured: Cycle 1, Day 1: before infusion, immediately following the infusion, and 3, 6, 10(±2), and 24 hours after the start of infusion. The 24-hour postinfusion sample was obtained before the start of the infusion on Day 2.
Area Under the Plasma Drug Concentration by Time Curve From Time 0 Until the Last Measurable Plasma Concentration (AUC0-t) for Bendamustine and Its Metabolites (M3 and M4)
Measured: Cycle 1, Day 1: before infusion, immediately following the infusion, and 3, 6, 10(±2), and 24 hours after the start of infusion. The 24-hour postinfusion sample was obtained before the start of the infusion on Day 2.
Area Under the Plasma Drug Concentration by Time Curve From Time 0 Until 24 Hours After Study Drug Administration (AUC0-24) for Bendamustine and Its Metabolites (M3 and M4)
Measured: Cycle 1, Day 1: before infusion, immediately following the infusion, and 3, 6, 10(±2), and 24 hours after the start of infusion. The 24-hour postinfusion sample was obtained before the start of the infusion on Day 2.

A Phase 1/2 study testing Bendamustine in people with Leukemia, run by Teva Branded Pharmaceutical Products R&D, Inc. at 50 sites in 12 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 10 inclusion and 9 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 23 May 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 50 sites in United States, Brazil, Mexico, South Korea, Australia and 7 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 1 Oct 2014). 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?
Recommended Phase II Dose (RP2D) of Bendamustine (time frame: Induction Cycle (21- to 35-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 NCT01088984, 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 23 May 2016.
