About this study
Official title: A Phase II Single-arm Open-labeled Study Evaluating Combination of Quizartinib and Omacetaxine Mepesuccinate (QUIZOM) in Newly Diagnosed or Relapsed/Refractory AML Carrying FLT3-ITD
The study aims to test if combination of quizartinib (AC220) and omacetaxine mepesuccinate (OM, also known as homoharringtonine) results in durable composite complete remission (CRc) in patients with newly diagnosed or relapsed/refractory (R/R) acute myeloid leukemia (AML) carrying FLT3-ITD (Fms-Like Tyrosine Kinase 3 - Internal Tandem Duplication).
Read the detailed description
The type of AML being studied in this clinical trial is known as FMS-like tyrosine kinase 3 (FLT3)-internal tandem duplication (ITD) positive AML. This type of AML has an alteration (or mutation) in genes, which may associated with high risk of relapse after conventional chemotherapy and hence an extremely poor clinical outcome.
Second generation FLT3 inhibitors including quizartinib are effective in inducing remission. However, their effects are only transient. There is an unmet clinic need to enhance their effectiveness, hence clinical application.
This is a Phase II single-arm open-labeled study. A total of 40 eligible patients with consent will be recruited, including 20 patients with newly diagnosed and 20 with R/R FLT3-ITD AML. For newly diagnosed patients, diagnostic bone marrow (BM) and/or peripheral blood (PB) will be evaluated by next generation sequencing (NGS) based on myeloid panel that comprises 54 myeloid genes as well as their in vitro response to QUIZOM based on an in-house platform that was established in our laboratory. FLT3-ITD allelic burden will also be evaluated. For R/R patients, FLT3-ITD status and allelic burden will be confirmed before QUIZOM treatment. Both groups of patients will receive quizartinib 30 mg daily continuously and OM 1.5 mg/m2 daily for 7 days every 28 days until progression or allogeneic hematopoietic stem cell transplantation (HSCT). BM examination will be performed on day 21 to document morphological response and FLT3-ITD allelic burden. At leukemia progression, BM and/or PB samples will be collected and their in vitro response to QUIZOM examined. The tyrosine kinase domain (TKD) of FLT3 will also be sequenced and FLT3-ITD allelic burden will be evaluated.
Eligible patients will receive QUIZOM comprising quizartinib and OM. The starting dose of quizartinib will be 30 mg/day unless the patients are taking a strong CYP3A4 inhibitor in which case the dose will be 20 mg /day. Quizartinib should be taken continuously throughout the treatment period unless there is no evidence of response at first assessment on day 21 or progressive disease at any time during the treatment.
OM will be given at 1.5 mg/m2/day (maximum dose 3 mg) for 7 days (concurrently with quizartinib) in 28-day cycle. QUIZOM will be continued until leukemia progression or allogeneic HSCT. Thereafter, patients will be followed up and information about disease status and survival will be collected.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Quizartinib and Omacetaxine Mepesuccinate Injection in people with AML and FLT3-ITD Mutation, run by The University of Hong Kong at 1 site in Hong Kong.
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 11 inclusion and 11 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: status not confirmed, as of the sponsor's last update on 10 Dec 2020. 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 Hong Kong. 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 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?
Results are not available in the source record.
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?
Complete remission (time frame: up to 16 weeks). 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 10 Dec 2020.
