Basic Information

• Recruitment Status: RECRUITING

Brief Summary

Chidamide in combination with venetoclax and azacitidine (VAC) were expected to improve remission rate of patients following to VA regimen treatment failure.

Detailed Description

Venetoclax and azacitidine has become the standard first-line treatment for elderly/unsuitable AML patients who can't tolerate for intense chemotherapy.

However, a proportion of patients who were not able to achieve remission after failing to VA regimen and then were given the second cycle, and their rate of achieving remission was even lower. Chidamide down-regulates the expression of MCL and is expected to improve the remission rate further in combination with VA regimen.

Conditions

Study Groups

VAC regimen

Group Type: EXPERIMENTAL

chidamide in combination with venetoclax and azacitidine (VAC)

Intervention Type: DRUG

Enrolled patients were given chidamide 10 mg every day on days 1-14, azacitidine 75mg/m2 every day on days 1-7, and oral venetoclax began at 100mg on day 1 and increased stepwise over 3 days to reach the target dose of 400mg (100mg, 200mg, and 400mg) on days 1-28. Dose adjustments for concomitant venetoclax with CYP3A4 inhibitors were made according to the literature.
