About this study
Official title: A Phase 1 Open-label Study of KPT-9274 in Patients With Relapsed and Refractory Acute Myeloid Leukemia
This study will evaluate the safety and tolerability of oral KPT-9274 for the treatment of patients with relapsed or refractory acute myeloid leukemia.
Read the detailed description
KPT-9274 is a first-in-class orally bioavailable, non-competitive, small molecule, dual modulator of p21 protein (Cdc42/Rac)-activated kinase 4 (PAK4) and nicotinamide phosphoribosyltransferase /PBEF/visfatin (NAMPT). NAMPT is the rate-limiting enzyme in the metabolic scavenging pathway that utilizes nicotinamide to replenish nicotinamide adenine dinucleotide (NAD), an essential metabolic cofactor and second messenger. Recent investigations have shown that in in vitro and in vivo models, NAMPT is uniquely essential for relapsed or refractory AML stem cells. Targeting relapsed AML stem cells, through targeting of NAMPT, may allow for a promising therapeutic opportunity for patients with relapsed or refractory AML.

What is being measured
The primary outcome is the main question the study is designed to answer.
Maximum Tolerated Dose (MTD)
Dose escalation will continue until the MTD is determined. The MTD is defined as the highest dose at which ≤1 patient experiences a DLT in Cycle 1. Count of participants who did not experience a DLT are listed in outcome measure data table.
Measured: 28 days
Secondary outcomes (1)
Count of Participants Who Did Not Experience a DLT Are Listed in the Outcome Measure Data Table
A RP2D equal to or less than the MTD will be declared after the MTD is determined and will be used for the Dose Expansion Phase, if conducted. After the RP2D is determined, a dose expansion phase, of up to 10 additional patients, might be conducted, in which a preliminary determination of efficacy will be conducted, using the ELN criteria.
Measured: 28 days

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing KPT-9274 in people with Acute Myeloid Leukemia and Acute Myeloid Leukemia, in Relapse, run by University of Colorado, Denver 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 12 inclusion and 10 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 27 Jan 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?
Yes. Results are posted in the registry (first posted 27 Jan 2026). 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) (time frame: 28 days). 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 NCT04914845, 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 27 Jan 2026.
