Research on Acute Promyelocytic Leukemia in Asia

The Acute Promyelocytic Leukaemia Asian Consortium (APL-AC) Project

Observational The University of Hong Kong · NCT04251754

This study is testing whether taking arsenic trioxide by mouth works as well as getting it through an IV for treating Acute Promyelocytic Leukemia in patients across Asia.

What this trial studies

This project aims to gather collaborative data on the epidemiology, clinicopathologic features, and treatment outcomes of newly diagnosed and relapsed Acute Promyelocytic Leukemia (APL) in Asia. It will compare the efficacy of oral arsenic trioxide (oral-As2O3) with intravenous arsenic trioxide (i.v.-As2O3) in treating APL, leveraging both retrospective and prospective data from various Asian countries. The study seeks to establish the long-term benefits of oral-As2O3, which has shown promising results in Hong Kong, and to facilitate its broader application across Asia.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 or older diagnosed with Acute Promyelocytic Leukemia with the PML/RARA fusion gene.

Not a fit: Patients with Acute Myeloid Leukemia that do not have the PML/RARA fusion gene or variant RARA translocation may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved treatment protocols for APL, enhancing patient outcomes across Asia.

How similar studies have performed: Other studies have shown success with arsenic trioxide treatments for APL, but this specific approach of oral-As2O3 in a broader Asian context is relatively novel.
