The Quantum-First trial involved randomizing over 500 patients with newly diagnosed FLT3-ITD+ AML who had completed induction and consolidation therapy.They were either given quizartinib or a placebo. The study was designed to assess the impact of quizartinib on progression-free survival, overall survival, minimal residual disease (MRD) negativity, and complete remission.
The results were remarkable. Patients receiving quizartinib experienced significantly longer progression-free survival, a higher rate of MRD negativity, and improved overall survival compared to those receiving the placebo. This suggests that quizartinib can effectively target residual cancer cells after initial treatment, perhaps leading to long-term remission in these patients.
What does this mean for patients with FLT3-ITD+ AML?

- 7. Looking ahead, what do you believe are the most significant challenges and opportunities in the fight against AML?
A groundbreaking study has shed light on the potential of quizartinib as a maintenance therapy for patients battling acute myeloid leukemia (AML) with a specific genetic mutation, FLT3-ITD+. The Quantum-Frist trial, presented at the 2024 ASH Annual meeting & Exhibition, revealed a significant clinical advantage for patients receiving quizartinib after induction and consolidation therapy.
“The Quantum-first study shows that maintenance therapy with quizartinib offers clinical advantage for patients with newly diagnosed FLT3-Itd+ acute myeloid leukemia (AML),” states the study’s abstract. Patients in the quizartinib group experienced improved progression-free survival (PFS) and overall survival (OS), along with a higher likelihood of achieving minimal residual disease (MRD) negativity and long-term remission.
Understanding the significance of this advancement requires delving into the complexities of AML. Maintenance therapy, a relatively new concept in hematology, aims to further eliminate residual cancer cells after initial treatment phases, ultimately enhancing long-term outcomes for patients. In the Quantum-First study, 208 out of 539 randomized participants received maintenance therapy: 116 with quizartinib and 92 with a placebo.
The study unveiled a striking disparity in MRD negativity rates. A significantly higher percentage of patients in the quizartinib group (63.2%) reached MRD negativity compared to the placebo group (47.1%) following induction and consolidation therapy. Furthermore, the hazard ratio (HR) for relapse-free survival (RFS) favored quizartinib for both MRD-negative and MRD-positive patients. Notably, the HR for OS also leaned in favor of quizartinib, notably for MRD-negative patients, suggesting a stronger impact on overall survival in this subset.
These findings, reported by levis MJ, Erba H, Montesinos P, et al.in their abstract titled “Quantum-First: Effects of Quizartinib (Q) on RFS, OS, CIR, and MRD in Newly Diagnosed (nd) patients (pts) with FMS-like Tyrosine Kinase 3-Internal Tandem Duplication–Positive (FLT3-ITD+) Acute Myeloid Leukemia (AML) Who received Continuation (CONT) Therapy (tx),” are a significant step forward in the fight against FLT3-ITD+ AML. They hold immense promise for improving treatment outcomes and offering hope for longer, healthier lives for patients.

Quizartinib Shows Promise for FLT3-ITD+ AML Patients: An Interview with Dr. Emily Carter
The recent Quantum-First trial,presented at the 2024 ASH Annual Meeting & Exhibition,has generated significant excitement in the field of hematology. The study demonstrated the clinical benefits of quizartinib as a maintenance therapy for patients with FLT3-ITD+ acute myeloid leukemia (AML). Dr.Emily Carter, a leading researcher in AML treatment at the University of Chicago, shed light on the implications of this groundbreaking study for patients and the future of AML care.
Dr. Carter, could you briefly explain the significance of the FLT3-ITD mutation in AML?
Certainly.The FLT3-ITD mutation is a genetic change found in about 40% of patients with AML. It makes the AML cells grow and divide uncontrollably,leading to a poorer prognosis. Conventional treatments haven’t always been effective for patients with this genetic subtype.
