study of tretinoin capsules in combination with azacitidine and venetoclax in treatment naïve participants with acute myeloid leukemia

Conditions: AML, Adult

Summary: this study was a prospective, two-arm, multicenter clinical trial to evaluate the efficacy and safety of tretinoin capsules combined with azacitidine and venetoclax in the treatment of newly diagnosed acute myeloid leukemia. azacitidine, venetoclax, and tretinoin may arrest cancer cell growth by demethylation, promoting cell differentiation, or killing cells, while reducing blood-related adverse effects by promoting cell differentiation.

this is a multi-center, non-controlled, open-label, phase 3 interventional study.young (≥18 and ≤60 years old) patients with newly diagnosed non m3, acute myeloid leukemia will receive a combination of aza+venetoclax+atra(ava regimen) or daunorubicin +cytarabine(da regimen) as induction treatment for 2 cycles. according to standard procedures, patients will receive one of the following consolidation regimens separately, including the ava regimen, or medium-dose cytarabine alone or in combination with anthracyclines regimen for 2cycle. after consolidation therapy, maintenance treatment could be given once a month for 4 times, then once every 3 months until progression. after the second induction therapy, allogeneic hematopoietic stem cell transplantation was recommended for patients with suitable donors. the primary endpoint is orr after second induction therapy.outcome measures included complete remission (cr)/complete remission with incomplete hematologic recovery (cri) .

Eligibility criteria:
inclusion criteria: * patients initially diagnosed with aml (excluding apl) according to who diagnostic criteria. * patients who have not previously received other induction therapies (excluding hydroxyurea and leukapheresis). * total white blood cell (wbc) count ≤ 25 × 10\^9/l. * ages 18 to 60 years, inclusive, with no gender restrictions. * ecog performance status score of 0-2. * total bilirubin ≤ 3 times the upper limit of normal (uln); alanine aminotransferase (alt) ≤ 3 times uln; aspartate aminotransferase (ast) ≤ 3 times uln; (excluding leukemia infiltration). * endogenous creatinine clearance rate ≥ 30 ml/min. * enrolled patients must be capable of understanding and willing to participate in the study, and must sign the informed consent form. exclusion criteria: * patients with acute promyelocytic leukemia (apl). * patients with concomitant central nervous system leukemia or extramedullary leukemia involvement, such as testicular infiltration. * patients with current or historical immunodeficiency virus infection. * patients with active hepatitis b or hepatitis c infection. * patients with a history of drug allergy, including but not limited to etoposide, azacitidine, venetoclax, daunorubicin, and cytarabine. * patients with active or progressive malignant tumors or severe infections. * patients with a left ventricular ejection fraction (lvef) of less than 30%, classified as new york heart association (nyha) class iii or above, and those deemed ineligible for enrollment by the investigator. * patients who are pregnant or breastfeeding. * patients who refuse to participate in the study.
