Motixafortide for MRD Sensitization in AML
What this study is about
This is a pilot phase I study evaluating the effect of motixafortide on determination of measurable residual disease (MRD) level in patients with acute myeloid leukemia (AML) who have completed induction treatment. Consenting and eligible patients will undergo the usual treatment (SOC) bone marrow and peripheral blood assessments with SOC MRD assays, followed by a single injection of motixafortide.
View original scientific description
This is a pilot phase I study evaluating the effect of motixafortide on determination of measurable residual disease (MRD) level in patients with acute myeloid leukemia (AML) who have completed induction treatment. Consenting and eligible patients will undergo standard of care (SOC) bone marrow and peripheral blood assessments with SOC MRD assays, followed by a single injection of motixafortide.
Interventions
DRUG
Motixafortide
Motixafortide is a CXCR4 inhibitor for the mobilization of hematopoietic stem progenitor cells (HSPCs) in patients undergoing autologous stem cell transplantation. It is provided as a single subcutaneous injection.
Primary outcome measures
Efficacy of motixafortide on measurable residual disease (MRD) levels
Time frame: Day 1 before motixafortide and Day 2 (estimated total time is 2 days)
The efficacy of motixafortide on MRD levels will be measured as the proportion of patients who have at least one of the following, as measured in peripheral blood, before versus after motixafortide: MRD negative to MRD positive conversion, or the 5% absolute increase in MRD level by flow cytometry, or leukemia defining polymerase-chain reaction (PCR) transcript (For fusion-driven leukemias or NPM1 and FLT3-ITD-mutated leukemias) or 5% increase in the VAF of recurrent leukemia associated gene mutations by next-generation sequencing (NGS).
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Diagnosed with acute myeloid leukemia (AML), excluding APL, treated with 1-2 cycles of front-line chemotherapy.
- Achieved CBC parameters compatible with complete remission as defined by ELN 2022.
- Planning to undergo a standard of care blood draw and bone marrow assessment with SOC MRD assays, including morphology, flow cytometry for MRD, NGS panels for MRD, and PCR tests for MRD as applicable.
- At least 18 years of age.
- ECOG performance status ≤ 2
- Life expectancy \> 3 months.
- Adequate organ function as defined below:
- Total bilirubin ≤ 2.0 x IULN
- AST(SGOT)/ALT(SGPT) ≤ 5.0 x IULN
- Creatinine clearance \> 30 mL/min by Cockcroft-Gault
- Ability to understand and willingness to sign an IRB approved written informed consent document.
Exclusion criteria
- Evidence of more than 5% blasts in in the peripheral blood by manual differential within 5 days prior to study enrollment.
- Prior history of allogeneic stem cell transplant.
- Prior or concurrent malignancy whose natural history has the potential to interfere with the safety or efficacy assessment of the investigational regimen. Patients with prior or concurrent malignancy that does NOT meet that definition are eligible for this trial
- Currently receiving any other investigational agents.
- A history of allergic reactions attributed to compounds of similar chemical or biologic composition to motixafortide.
- Uncontrolled intercurrent illness including, but not limited to: ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, or cardiac arrhythmia. Patients with a known history or current symptoms of cardiac disease, or history of treatment with cardiotoxic agents, should have a clinical risk assessment of cardiac function using the New York Heart Association Function Classification; to be eligible for this trial, patients should be a class 2B or better.
- Pregnant and/or breastfeeding. Women of childbearing potential must have a negative pregnancy test within 14 days of study entry.
- HIV-infected if not on effective anti-retroviral therapy with undetectable viral load for 6 months. Patients with HIV who are receiving effective anti-retroviral therapy and have had an undetectable viral load for at least 6 months are eligible. HIV testing not required in the absence of known history of infection.
- Evidence of chronic hepatitis B virus (HBV) that is detectable on suppressive therapy. Patients with evidence of chronic HBV infection with undetectable HBV viral load on suppressive therapy are eligible. HBV testing not required in the absence of known history of infection.
- History of hepatitis C virus (HCV) infection that has not been cured or that has a detectable viral load. Patients with a history of HCV that has been treated and cured are eligible. Patients with HCV infection who are currently on treatment and have an undetectable HCV viral load are eligible. HCV testing not required in the absence of known history of infection.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
