What this trial studies

This phase 1 trial investigates the combination of pegylated arginine deiminase (ADI-PEG 20) with venetoclax and azacitidine in patients with acute myeloid leukemia (AML). The study includes two cohorts: one for patients with relapsed or refractory AML and another for newly diagnosed high-risk AML patients. The trial is open-label and single-arm, focusing on determining the recommended phase 2 dose (RP2D) of ADI-PEG 20 while monitoring for dose-limiting toxicities (DLT). Treatment may continue for up to 24 cycles or until a maximum of 104 doses of ADI-PEG 20 are administered.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with either relapsed/refractory AML or newly diagnosed high-risk AML who are not suitable for intensive chemotherapy.

Not a fit: Patients with low-risk AML or those who are candidates for intensive chemotherapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment combination could improve response rates in patients with high-risk acute myeloid leukemia.

How similar studies have performed: Other studies have shown promising results with similar combinations of venetoclax and azacitidine, suggesting potential for success in this novel approach.

Eligibility criteria

Inclusion Criteria:

* Cohort 1: Previously treated (relapsed/recurrent) or refractory AML based on the 2022 revision to the World Health Organization (WHO) criteria (Arber 2022)
* Cohort 2: Untreated AML per 2022 WHO (Arber 2022) criteria with high-risk features and not a candidate for intensive chemotherapy because of age 60 years or older, age-related comorbidities, cardiac disease, prior anthracycline use, high probability of treatment-related mortality, or otherwise would not benefit from intensive chemotherapy treatment.
* Age ≥ 18 years
* Life expectancy reasonably adequate for evaluating the treatment
* White blood cell (WBC) count of 10 × 109/L or less. (Use of hydroxyurea to control WBC is allowed till 48 hours prior to protocol treatment)
* Adequate renal function: Creatinine ≤ 1.5 x upper limit of normal (ULN) or creatinine clearance \> 40 mL/minute (measured or calculated according to the Cockcroft-Gault formula)
* Adequate liver function

  * Total bilirubin ≤ 1.5 x ULN
  * ALT and AST both ≤ 2.5 x institutional ULN or ≤ 5 times the ULN for patients with leukemic involvement of liver

Exclusion Criteria:

* Prior treatments as follows:

  1. Cohort 1: \>2 cycles of prior combination treatment with venetoclax+hypomethelating agent (i.e. azacitidine, decitabine) is exclusionary. All other prior treatment for antecedent hematological disorders and/or for AML is permitted.
  2. Cohort 2: Prior treatment for antecedent hematological disorders with venetoclax or chemotherapy or any prior treatment for their AML is exclusionary. However, treatment with other agents, including hydroxyurea or ≤2 cycles of hypomethylating agent (i.e. azacitidine, decitabine), for MDS or myeloproliferative neoplasm is permitted.
* Cohort 2: Favorable risk AML per European LeukemiaNet (ELN) 2022 criteria (Döhner 2022)
* Known active CNS involvement by leukemia
