About this study
Official title: A Phase Ib Investigation of the LSD1 Inhibitor Iadademstat (ORY-1001) in Combination With Azacitidine and Venetoclax in Newly Diagnosed AML
This phase I trial tests the safety, side effects, and best dose of iadademstat when given together with azacitidine and venetoclax in treating patients with newly diagnosed acute myeloid leukemia (AML). Iadademstat inhibits the LSD1 protein and may lead to inhibition of cell growth in LSD1-overexpressing cancer cells. Chemotherapy drugs, such as azacitidine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Venetoclax is in a class of medications called B-cell lymphoma-2 (Bcl-2) inhibitors. It may stop the growth of cancer cells by blocking Bcl-2, a protein needed for cancer cell survival. Giving iadademstat with azacitidine and venetoclax may be safe, tolerable and/or effective in treating patients with newly diagnosed AML who cannot undergo intensive chemotherapy.
Read the detailed description
PRIMARY OBJECTIVE:
- Determine the maximum tolerated dose (MTD) and/or recommended phase 2 dose (RP2D) of iadademstat (IADA) when administered as part of the investigational combination (i.e., iadademstat + azacitidine + venetoclax [IADA+AZA+VEN]).
SECONDARY OBJECTIVES:
- Assess the preliminary efficacy of the investigational regimen based on disease remission.
II. Assess the preliminary efficacy of the investigational regimen based on clinical response.
III. Assess the safety of the investigational regimen.
EXPLORATORY OBJECTIVES:
- Assess survival in the absence of treatment failure, hematologic relapse, or progressive disease.
II. Assess overall survival.
III. Assess duration of response, based on morphological assessments.
IV. Identify mechanisms of transcriptional reprogramming and cell death.
- Identify predictive biomarkers of response to LSD1 inhibition.
VI. Assess participant quality of life using Patient-Reported Outcomes Common Terminology Criteria for Adverse Events (PRO-CTCAE).
OUTLINE: This is a dose-escalation study of iadademstat in combination with azacitidine and venetoclax.
Patients receive iadademstat orally (PO) once daily (QD) on days 1-5, 8-12, and 15-19. Patients also receive venetoclax PO QD on days 1-21 or 1-28 and azacitidine subcutaneously (SC) or intravenously (IV) QD on days 1-7 or 1-5 and 8-9. Patients with complete remission (CR), CR with partial hematologic recovery (CRh), CR with incomplete blood count recovery, (CRi), or morphologic leukemia-free state (MLFS) after cycle 1 continue to receive IADA PO QD on days 1-5, 8-12, and 15-19, azacitidine SC or IV QD on days 1-7 or 1-5 and 8-9, and venetoclax PO QD on days 1-7, 1-14, 1-21 or 1-28 of subsequent cycles. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients undergo echocardiography (ECHO) or multigated acquisition scan (MUGA) during screening and as clinically indicated on study. Patients undergo bone marrow biopsy throughout the trial. Additionally, patients undergo blood sample collection during screening and on the trial.

What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence of dose-limiting toxicities (DLTs) within specific iadademstat (IADA) dose levels
Will be assessed by National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0 (CTCAE v 5.0).
Measured: Start of IADA (cycle 1 of combination therapy) to end of cycle 1 (each cycle is 28 days)
Secondary outcomes (3)
Percentage of efficacy-evaluable participants achieving composite complete remission (cCR)
Will be defined as achievement of complete remission (CR) or CR with partial hematologic recovery (CRh) or CR with incomplete blood count recovery (CRi) while on iadademstat+ azacitidine + venetoclax (IADA+AZA+VEN). Will be estimated for the efficacy-evaluable population with point estimates and exact binomial confidence intervals (CIs) as summary statistics. CRc rate will also be modeled with univariable logistic regressions to determine if any baseline patient or disease feature is correlated with clinical response as defined by these efficacy metrics.
Measured: Start of IADA (cycle 1 of combination therapy) to end of investigational study treatment, average of 1 year
Percentage of efficacy-evaluable participants achieving an overall response (ORR)
Will be defined as the proportion of efficacy-evaluable participants who attain a PR or better (i.e., CR, CRh, CRi, morphologic leukemia-free state, or partial remission [PR]) while on IADA+AZA+VEN. Will be estimated for the efficacy-evaluable population with point estimates and exact binomial CIs as summary statistics. ORR will also be modeled with univariable logistic regressions to determine if any baseline patient or disease feature is correlated with clinical response as defined by these efficacy metrics.
Measured: Start of IADA (cycle 1 of combination therapy) to end of investigational study treatment, average of 1 year
Incidence of treatment-emergent grade ≥ 3 adverse events (AEs)
Will be reported with descriptive statistics, at the overall patient level and by grade, attribution (i.e., a separate table for treatment-related AEs), and seriousness (i.e., separate tables for serious adverse events).
Measured: Start of IADA (cycle 1 of combination therapy) to end of investigational study treatment, average of 1 year

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Azacitidine, Biospecimen Collection and Bone Marrow Biopsy in people with Acute Myeloid Leukemia and Myelodysplastic Syndrome/Acute Myeloid Leukemia, run by OHSU Knight Cancer Institute at 1 site in United States.
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 36 inclusion and 21 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: looking for participants now, as of the sponsor's last update on 30 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence of dose-limiting toxicities (DLTs) within specific iadademstat (IADA) dose levels (time frame: Start of IADA (cycle 1 of combination therapy) to end of cycle 1 (each cycle is 28 days)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 30 Jun 2026.
