Official title

A Single-center, Single-arm, Prospective Clinical Study of Intermediate-dose Cytarabine in Combination With Venetoclax for Consolidation Therapy of Middle- and High-risk Acute Myeloid Leukemia in The Elderly

Overview

A Single-center, Single-arm, Prospective Clinical Study of Intermediate-dose Cytarabine in Combination with Venetoclax for Consolidation Therapy of Middle- and High-risk Acute Myeloid Leukemia in the Elderly

Detailed description

This study is designed to be a prospective cohort study conducted at the First Hospital of Jilin University. The target populations of this study are patients with Middle- and High-risk Acute Myeloid Leukemia in the elderly who received intermediate-dose cytarabine in combination with venetoclax for consolidation therapy from June 1, 2025to December 31, 2026. It is expected to enroll 68 subjects in this study. The subjects' data such as demographics and other baseline characteristics, medications, prognosis, will be collected, and statistical analysis of data will be conducted to compare the effectiveness outcome measures

Interventions

• Drug Intermediate-dose Cytarabine in Combination with Venetoclax
  Elderly patients with Middle- and High-risk Acute Myeloid Leukemia who received the Intermediate-dose Cytarabine in Combination with Venetoclax at the First Hospital of Jilin University from March 1, 2024 to December 31, 2026.

Primary outcome measures

• Relapse-Free Survival(RFS) [Time frame: From date of index treatment to death, disease progression, or end of study, whichever came first, assessed up to 36 months.]

Secondary outcome measures (3)

• Overall Survival (OS) [Time frame: From date of index treatment to death, disease progression, or end of study, whichever came first, assessed up to 36 months.]
• Cumulative Relapse Rate (CIR) [Time frame: From date of index treatment to death, disease progression, or end of study, whichever came first, assessed up to 36 months.]
• MRD Negative Conversion Rate [Time frame: From date of index treatment to death, disease progression, or end of study, whichever came first, assessed up to 36 months.]

Eligibility criteria

Inclusion criteria
