How is APL initially treated?
For most patients, the initial course of treatment for APL is a form of vitamin A called all-trans retinoic acid (ATRA) combined with chemotherapy. • Up to 90% of patients typically respond to ATRA-based chemotherapy • Up to 30% of patients who respond to ATRA-based chemotherapy still may experience a relapse For these patients who do not respond or experience a relapse, there is another option. TRISENOX® (arsenic trioxide) injection is an anticancer drug proven effective in patients with relapsed or refractory APL.
