Abstract
Realgar-Indigo Naturalis Formula (RIF) is an oral form of arsenic that is effective against acute promyelocytic leukemia (APL). This multicenter, randomized, controlled trial compared the efficacy of all-trans retinoic acid (ATRA) plus RIF with ATRA plus arsenic trioxide (ATO) in a simplified regimen for non-high-risk APL. Following induction therapy with ATRA and ATO, participants were randomly assigned to receive either ATRA plus ATO or ATRA plus RIF both in a 2-week on 2-week off schedule for consolidation therapy. Once achieving molecular complete remission, the regimen was administered for a total of 6 cycles. All of 108 eligible patients achieved hematological complete remission after induction therapy. The median follow-up time was 29 months. The primary endpoint of two-year disease-free survival was 97% in the ATRA-RIF arm and 98% in the ATRA-ATO arm, respectively. (The ATRA-RIF arm was found to be non-inferior to the ATRA-ATO arm, (P < .01), with a percentage difference of -1% (95%CI, -4.8 to 6.9). No deaths have been observed. Most adverse events were moderate. This study confirms the noninferiority of RIF to ATO for non-high-risk APL, while also offering a more favorable regimen schedule for post-remission therapy.
