About this study
Official title: Measurable-residual Disease (MRD) Monitoring of Nucleophosmin 1 (NPM1)-Mutated Acute Myeloid Leukaemia (AML) and Pre-emptive Therapy With Oral Arsenic Trioxide-based Regimen
A prospective open-label phase 2 study will be designed to assess the efficacy of oral arsenic trioxide plus azacitidine in preventing relapses in patients with NPM1-mutant AML. After screening and eligibility assessment, patients will receive treatment with oral arsenic trioxide plus azacitidine for 12 months. The recruitment period will last for 24 months and it will take approximately 36 months for study completion.
Read the detailed description
Eligible subjects with NPM1 MRD positivity will receive oral arsenic trioxide (oral-As2O3) (Arsenol ®) (5-10mg per day, from days 1-7 per cycle), ascorbic acid (1g per day, from days 1 - 7 per cycle) plus azacitidine (75mg/m2 per day subcutaneously, from days 1 to 3 per cycle). Each cycle of oral-As2O3 plus azacitidine will be given once every 28 days. The total duration of treatment is 12 months (12 cycles). Treatment will be day-care and outpatient based. Reduction in the dosage and duration of oral-As2O3 is required if the subject is experiencing adverse events (AEs). In case of grade 3 or above toxicity, the dosage of oral-As2O3 will be reduced to 5mg per day. Changes or interruption in dosages, their dates and time points will be recorded on the dosage administration record and the electronic case report form (eCRF).

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
A prospective open-label phase 2 study will be designed to assess the efficacy of oral arsenic trioxide plus azacitidine in preventing relapses in patients with NPM1-mutant AML. After screening and eligibility assessment, patients will receive treatment with oral arsenic trioxide plus azacitidine for 12 months. The recruitment period will last for 24 months and it will take approximately 36 months for study completion.
Detailed description
Eligible subjects with NPM1 MRD positivity will receive oral arsenic trioxide (oral-As2O3) (Arsenol ®) (5-10mg per day, from days 1-7 per cycle), ascorbic acid (1g per day, from days 1 - 7 per cycle) plus azacitidine (75mg/m2 per day subcutaneously, from days 1 to 3 per cycle). Each cycle of oral-As2O3 plus azacitidine will be given once every 28 days. The total duration of treatment is 12 months (12 cycles). Treatment will be day-care and outpatient based. Reduction in the dosage and duration of oral-As2O3 is required if the subject is experiencing adverse events (AEs). In case of grade 3 or above toxicity, the dosage of oral-As2O3 will be reduced to 5mg per day. Changes or interruption in dosages, their dates and time points will be recorded on the dosage administration record and the electronic case report form (eCRF).

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Oral Arsenic Trioxide Formulation in people with NPMc+ AML, 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 8 inclusion and 4 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 4 Oct 2022. 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?
Contact Harinder Gill, MD (+852 22554542, gillhsh@hku.hk), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Rate of NPM1 MRD negativity. (time frame: 36 months). 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 NCT04689815, which also lists 8 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 4 Oct 2022.
