  12. Number of Participants With Adverse Events (AEs)

    An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment. The investigator assesses the relationship of each event to the use of study. A serious adverse event (SAE) is an event that results in death, is life-threatening, requires or prolongs hospitalization, results in a congenital anomaly, persistent or significant disability/incapacity or is an important medical event that, based on medical judgment, may jeopardize the participant and may require medical or surgical intervention to prevent any of the outcomes listed above. Treatment-emergent adverse events/treatment-emergent serious adverse events (TEAEs/TESAEs) are defined as any event that began or worsened in severity on or after the first dose of study drug.

    Measured: Up to Maximum of 24 months

Secondary outcomes (15)

  1. Event-Free Survival (EFS)

  13. Rate of Hematologic Improvement (HI)

    Proportion of participants with HI (erythroid/platelet/neutrophil responses)

    Measured: Measured from Cycle 1 Day 1 as long as the subject continues to benefit, or until the occurrence of unacceptable toxicity, death, exercise of investigator discretion, or withdrawal of consent, and for an anticipated maximum duration of 24 months.

    Proportion of participants with marrow complete remission with or without hematological improvement.

    Measured: Measured from Cycle 1 Day 1 (C1D1) as long as the subject continues to benefit, or until the occurrence of unacceptable toxicity, death, exercise of investigator discretion, or withdrawal of consent, and for an anticipated maximum duration of 24 months.

  15. Duration of ORR

    Duration of response (ORR) will be defined as the number of days from the date of first response (CR or PR) to the earliest documentation of progressive disease or death of any cause, whichever occurs earlier.

    Measured: Measured from the date of first response (CR or PR) to the earliest documentation of progressive disease or death of any cause, and for an anticipated maximum duration of 24 months.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing venetoclax and azacitidine in people with Myelodysplastic Syndromes (MDS), run by AbbVie at 23 sites in 3 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 8 inclusion and 6 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 9 May 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 23 sites in United States, Germany, Australia. 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 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.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

AUCt for azacitidine (time frame: Up to 32 days). The study lists 12 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 NCT02966782, which also lists 2 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 9 May 2023; AzTrials last refreshed its copy on 6 Nov 2026.
