VAC Regimen for AML Patients Who Failed to Response to VA Regimen

Официальное название

A Clinical Study of Chidamide in Combination With Venetoclax and Azacitidine (VAC) for Patients With Acute Myeloid Leukemia Who Did Not Achieve CR/CRi/MLFS (PR or NR) With One Cycle of Venetoclax and Azacitidine (VA).

Обзор

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

Подробное описание

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.

Вмешательства

• Препарат chidamide in combination with venetoclax and azacitidine (VAC)
  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.
