Exploratory Study of Venetoclax, Homoharringtonine, Azacitidine Plus G-CSF for Newly Diagnosed AML (VHAG)

Starting soon · Phase 2

Conditions studied: Acute Myeloid Leukemia (AML)

In brief

This study is a single-arm, prospective, multi-center exploratory clinical trial. A total of 61 patients with newly diagnosed acute myeloid leukemia (AML) who are not suitable for intensive chemotherapy will be enrolled. The Simon two-stage design will be adopted to control the type I and type II errors, with the minimum acceptable composite remission rate of 65% and a power of 80%. Prior to treatment, subjects will undergo screening within 28 days, including bone marrow aspiration, genetic testing, ECOG performance status assessment, and organ function evaluation. Data will be recorded in Excel and subject to unified quality control. During the treatment period, G-CSF (granulocyte colony-stimulating factor) will be administered subcutaneously as appropriate, and supportive care such as antiemetic and hydration therapy will be provided routinely. For patients who achieve remission, individualized consolidation therapy will be given: those eligible for transplantation will undergo allogeneic hematopoietic stem cell transplantation; those who can tolerate moderate-intensity treatment will receive consolidation with medium-dose cytarabine first, followed by 4 cycles of VHAG regimen consolidation. Patients with FLT3 mutations will receive additional targeted therapy during consolidation. Safety assessment will be conducted in accordance with the NCI-CTCAE Version 5.0. For grade 4 hematological toxicity or severe non-hematological toxicity, the treatment dose will be adjusted or the treatment will be suspended. Severe adverse events will be reported in a timely manner, and all research-related data will be retained for at least 10 years in accordance with relevant regulations.

Concurrent participation in another clinical trial.
AML with central nervous system (CNS) involvement confirmed by imaging or cerebrospinal fluid examination.
Positive HIV antibody during the screening period.
Positive HBsAg or HCV antibody with a high-sensitivity viral load above the lower limit of detection within 3 months (excluding those who are cured or with persistent low-level replication).
Ingestion of grapefruit, grapefruit juice, Seville oranges, star fruit, or their products within 72 hours prior to the first dose.
Chronic respiratory failure requiring long-term oxygen therapy.
Presence of severe cardiac, hepatic, renal, endocrine, metabolic, immune, neurological, or psychiatric disorders.
History of hypersensitivity to the study drug (including azacitidine excipients).
Impaired drug absorption due to malabsorption syndrome, short bowel syndrome, or other conditions affecting oral drug absorption.
Active tuberculosis or other severe infections requiring intravenous anti-infective therapy for ≥7 days.
Presence of a second malignancy within 2 years prior to enrollment, excluding cured carcinoma in situ of the cervix or breast, completely resected basal cell carcinoma or localized squamous cell carcinoma of the skin, or localized malignancies cured by surgery and requiring no further follow-up.
The investigator judges that the patient is otherwise ineligible to participate in this study.
