Oral Arsenic With ATRA for Newly Diagnosed Patients With Acute Promyelocytic Leukemia
115 patients around the world
Available in Brazil
This is a non-randomized, multicenter, prospective study aimed at treating patients with
newly diagnosed acute promyelocytic leukemia (APL) using a combination of oral arsenic
and ATRA. For patients classified as high-risk (white blood cell count >10×10⁹/L),
low-dose chemotherapy will be added. The primary objective is to evaluate the 2-year
overall survival (OS) in these patients, comparing it to a historical control group
treated with ATRA and chemotherapy according to the IC-APL 2006 protocol. Secondary
objectives include: Comparing complete response rates, disease-free survival, cumulative
incidence of relapse, and early mortality with those reported in the IC-APL 2006 study
(historical controls), as well as with outcomes reported in developed countries;
Comparing the cumulative incidence of myelodysplasia or secondary leukemia; Comparing the
toxicity profile with historical data; Assessing the molecular remission rate after
consolidation; Evaluating the reduction in PML/RARA transcript levels during treatment;
Comparing the duration of patient hospitalization with historical results.
