HPB-092: A novel FLT3 and IRAK4 dual inhibitor for the treatments of AML and MDS (AACR 2025) - "Compared to the approved FLT3 inhibitors gilteritinib and quizartinib, and the clinical-stage FLT3/IRAK4 dual inhibitor CA-4948, HPB-092 showed comparable or superior inhibitory potency against mutated forms of FLT3, improved IRAK4 inhibition, better selectivity, minimal inhibition of CYP3A4, no hERG activity, and an overall favorable safety profile, potentially benefiting a broader range of hematological malignancies. HPB-092 has received FDA clearance for a phase 1 dose-escalation and expansion study to assess its safety, tolerability, pharmacokinetics, pharmacodynamics, and preliminary efficacy in adult patients with relapsed or refractory AML, particularly those with FLT3 mutations and U2AF1 or SF3B1 mutations, at a leading cancer center in the US."

A novel and potent FLT3 and IRAK4 dual inhibitor for the treatment of acute myeloid leukemia (AACR 2023) - "Emavusertib (CA-4948), an IRAK4/FLT3 inhibitor, is currently in phase I clinical trials. In addition, no rhabdomyolysis side-effect was observed upon histological analysis. These results underscore the potential therapeutic benefit and safety profile of HPB-092 for the treatment of AML, especially in patients with mutations in U2AF1 or SFF3B1 spliceosome."
