Dual Growth Factor (rhTPO + G-CSF) and Chemotherapy Combination Regimen for Elderly Patients With Acute Myeloid Leukemia: A Phase II Single-Arm Multicenter Study
Visão geral do estudo
Descrição detalhada
Acute myeloid leukemia (AML) is one of the most common hematologic malignancies and affects older adults. The median age at diagnosis is 67 years. As the elderly increasingly account for a greater population percentage, AML is becoming more problematic. During the past 30 years, outcomes have improved for younger patients, whereas the prospects for older adults (> 60 years) have remained poor. The response rate in older adults given standard induction regimens is < 50%, and median overall survival (OS) is < 1 year. Older adults elderly are also inordinately burdened by unfavorable cytogenetic defects, medical comorbidities, and reduced tolerability to intensive chemotherapeutic protocols. These vulnerabilities predispose older adults to poorer outcomes than their younger counterparts, conferring lower response rates and shortened survival times (progression-free and overall survival [OS]). Safe and effective treatments for elderly patients with AML are thus urgently needed.
In 2000, Saito et al introduced a regimen of granulocyte colony-stimulating factor (G-CSF) plus low-dose cytarabine (ara-C) and aclarubicin (ACR) for use in this setting (CAG regimen), in an attempt to incorporate a hematologic growth factor in AML induction therapy, rather than relying on supportive care. The addition of decitabine, a demethylation agent, further improved the prognosis, yielding a 10-month median OS. This successful use of G-CSF in an induction regimen for AML confirmed its utility, helping to increase efficacy and reduce side effects in elderly patients.
Thrombopoietin (TPO) is a major factor in regulating megakaryocytic proliferation, maturation, and platelet formation. Recombinant human TPO (rhTPO) has been approved by China's State Food and Drug Administration to treat thrombocytopenia after chemotherapy. TPO and c-MPL receptors are also involved in various physiologic processes, such as mitigating myocardial injury, nerve repair, vascular regeneration, sex hormone secretion, and immune regulation. However, the role of rhTPO in an induction regimen for AML is unreported as yet.
To determine if adding rhTPO to D-CAG (G-CSF) will increase the overall response rate (ORR) while decreasing the side effect of toxic agents, we designed a regimen of rhTPO and G-CSF in combination with decitabine, cytarabine, and aclarubicin (D-CTAG regimen). This trial aimed to determine the safety and efficacy of this D-CTAG regimen as a treatment for older adult patients with newly diagnosed AML.
