Oral Arsenic Trioxide for NPM1-mutated AML

Overview

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.

    • Intervention Model: Single Group Assignment
    • Primary Purpose: Treatment
    • Masking: None (Open Label)
  • Study Primary Completion Date: December 31, 2023

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).

Interventions

    • 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.

Arms, Groups and Cohorts

  • Experimental: Oral arsenic trioxide-Azacitidine
    • 12 monthly cycles of 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).

Clinical Trial Outcome Measures

Primary Measures

  • Rate of NPM1 MRD negativity.
    • Time Frame: 36 months
    • This is defined as undetectable NPM1 mutant transcript with RQ-PCR on both the PB and BM following treatment, at a limit of detection of 10^-5.

Secondary Measures

  • Duration of response
    • Time Frame: 36 months
    • defined as the time from achievement of undetectable NPM1 MRD to Documented molecular recurrence (defined as detectable MRD on PB or BM at a limit of detection of 10^5.
  • Leukaemia-free survival (LFS)
    • Time Frame: 36 months
    • This is defined as the time, in months, from the start of oral-As2O3 plus azacitidine to morphologic relapse of AML.
  • Safety of oral-As2O3 plus azacitidine, assessed using the common toxicity criteria for adverse events (CTCAE) version 5.0.
    • Time Frame: 36 months
    • The incidence of treatment emergent adverse events will be determined as a measure of safety
