Hematologic DLT was defined as failure of platelet recovery to 25 × 10^9/L or greater and absolute neutrophil count (ANC) to 0.5 × 10^9/L or greater within 14 days of the last dose of venetoclax in the absence of residual AML.

    Measured: Up to 28 days (Cycle 1)

  2. Phase 1: Maximum Observed Plasma Concentration (Cmax) of Venetoclax

    The highest concentration that a drug achieves in the blood after administration in a dosing interval.

    Measured: Cycle 1, Day 10 at predose and 2, 4, 6, 8, and 24 hours postdose (venetoclax with LDAC); Cycle 1, Day 18 at predose, 2, 4, 6, 8, and 24 hours postdose (venetoclax alone)

  3. Phase 1: Time to Maximum Observed Plasma Concentration (Tmax) of Venetoclax

    The time at which the maximum plasma concentration (Cmax) is observed.

    Measured: Cycle 1, Day 10 at predose and 2, 4, 6, 8, and 24 hours postdose (venetoclax with LDAC); Cycle 1, Day 18 at predose, 2, 4, 6, 8, and 24 hours postdose (venetoclax alone)

  4. Phase 1: Area Under the Plasma Concentration-Time Curve Over Time From 0 to 24 Hours (AUC0-24) of Venetoclax

    PR: all of the hematologic values for a CR but with a decrease of at least 50% in the percentage of blasts to 5% to 25% in the bone marrow aspirate.

    Measured: Response was assessed at Cycle 2, Day 1, Cycle 4, Day 1, and every 3 cycles thereafter; median duration of treatment was 4.2 months.

  9. Number of Participants With Treatment-emergent Adverse Events (TEAEs)

    An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. The investigator rated the severity of each AE according to the CTCAE Version 4.0 and the following:

    Grade 1: The AE is transient and easily tolerated (mild).

    Grade 2: The AE causes discomfort and interrupts usual activities (moderate).

    Grade 3: The AE causes considerable interference with usual activities and may be incapacitating (moderate to severe).

    Grade 4: The AE is life threatening requiring urgent intervention.

    Grade 5: The AE resulted in death.

    The investigator assessed each event as either having a reasonable possibility or no reasonable possibility of being related to the use of study drug.

    Treatment-emergent events are defined as events that began or worsened in severity after the first dose of study drug.

    Measured: From first dose of study drug until 30 days after last dose of study drug; median (minimum, maximum) duration of treatment was 4.1 (0.2, 62.8) months overall.

OS was estimated using Kaplan-Meier methodology. Participants who were still alive were censored at the analysis date.

    Measured: Median duration of follow-up was 44.5 months (range: 0.3 to 63.7)

  17. Post Baseline Transfusion Independence Rate

    Post baseline transfusion independence rate was estimated as the percentage of participants who achieved transfusion independence during the evaluation period. Post-baseline transfusion independence is defined as a period of at least 56 days (≥ 56 days) with no RBC or platelet transfusion during the evaluation period. The evaluation period is from the first dose of study drug to the last dose of study drug until the 30 day follow-up visit, disease progression (including clinical progression), or death, whichever was earlier.

    Results are reported for participants who achieved both RBC and platelet transfusion independence and for participants who received RBC transfusion independence and platelet transfusion independence.

    Measured: From the first dose of study drug to the last dose of study drug plus 30 days, disease progression (including clinical progression), or death, whichever was earlier; median duration of treatment was 4.2 months.

  18. Post Baseline Transfusion Independence Rate Among Participants Transfusion-dependent at Baseline

    Post baseline transfusion independence rate was estimated as the percentage of participants who achieved transfusion independence during the evaluation period. Post-baseline transfusion independence is defined as a period of at least 56 days (≥ 56 days) with no RBC or platelet transfusion during the evaluation period. The evaluation period is from the first dose of study drug to the last dose of study drug until the 30 day follow-up visit, disease progression (including clinical progression), or death, whichever was earlier.

    Results are reported for participants who achieved both RBC and platelet transfusion independence and for participants who received RBC transfusion independence and platelet transfusion independence.

    Measured: From the first dose of study drug to the last dose of study drug plus 30 days, disease progression (including clinical progression), or death, whichever was earlier; median duration of treatment was 4.2 months.

  19. Duration of Post Baseline Transfusion Independence

    The duration of transfusion independence is defined as the first time period that a participant received no RBC/platelet transfusions for at least 56 days during the evaluation period.

    Post-baseline transfusion independence is defined as a period of at least 56 days with no RBC or platelet transfusion during the evaluation period. The evaluation period is from the first dose of study drug to the last dose of study drug until the 30 day follow-up visit, disease progression (including clinical progression), or death, whichever was earlier.

    Measured: From the first dose of study drug to the last dose of study drug plus 30 days, disease progression (including clinical progression), or death, whichever was earlier; median duration of treatment was 4.2 months.

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing Venetoclax and Cytarabine in people with Acute Myelogenous Leukemia and AML, run by AbbVie at 9 sites in 4 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 27 inclusion and 20 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 29 Aug 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites in United States, Australia, Germany, Italy. 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 29 Aug 2022). 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?

Phase 1: Number of Participants With Dose-limiting Toxicities (time frame: Up to 28 days (Cycle 1)). The study lists 9 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 NCT02287233, which also lists 3 linked publications.

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 29 Aug 2022.
