PHI-101, a Novel FLT3 TKI, Shows Clinical Efficacy in Relapsed/Refractory FLT3-Mutated AML (ASH 2024) - P1a/1b | "75% of these patients had received prior FLT3 inhibitors (Gilteritinib (7), Midostaurin (3), Sorafenib (1), HM43239 (1)). The recommended phase 2 dose will be 160 mg once-daily which resulted in Cmax and AUC0-24 plasma concentrations in Phase 1b of 259 ng/ml and 3,920 ng/ml at cycle 1 day 1. Conclusion : Once-daily dosing of single-agent PHI-101 had a distinct tolerability profile and showed excellent anti-tumor activity across FLT3i-pretreated and FLT3i-naïve patients with R/R FLT3 mutant AML."

Evaluation of Synergistic Anti-Leukemic Efficacy of PHI-101 in Preclinical Model of FLT3-ITD Acute Myeloid Leukemia (ASH 2023) - "Study Design and Combination effects of simultaneous versus sequential treatment of PHI-101 with other agents, including daunorubicin, cytarabine, venetoclax (Ven), and azacytidine (Aza) were tested using human leukemia cell lines harboring FLT3-ITD mutations (MV4-11, Molm13, Molm14) or FLT3-wild type as controls...The GI 50 of the gilteritinib was 5... Treatment of AML cells with the combination of Ven or Aza with PHI-101 in vitro induced rapid induction of apoptosis and inhibition of cell growth that showed significant synergy. In vivo data showed improved efficacy for the combination treatment with these agents. In vitro and in vivo data from the preclinical AML models provides a rationale to evaluate the activity of PHI-101 in combination for patients who are ineligible for more intensive chemotherapeutic induction therapy."

The third-generation FLT-3 inhibitor, PLM-102, is a promising therapeutic option for venetoclax-resistant AML (AACR 2025) - "Notably, PLM-102 demonstrated the highest tumor growth inhibitory (TGI) efficacy compared with those of other FLT3 inhibitors including tuspetinib, gilteritinib and PHI-101. In conclusion, PLM-102 completely inhibited FLT3 kinase and its downstream signaling including AKT and STAT3, inducing apoptosis in VR AML cells along with significant inhibition of the tumor growth in the VR xenograft mouse model. These findings suggest that PLM-102, a third-generation FLT-3 inhibitor, is a promising candidate for overcoming venetoclax resistance and could serve as a therapeutic option for venetoclax-resistant AML."
