A Phase 1 Study of AJ1-11095 in Patients With Primary Myelofibrosis (PMF), Post-Polycythemia Vera Myelofibrosis (PPV-MF), or Post-Essential Thrombocythemia Myelofibrosis (PET-MF) Who Have Been Failed by a Type I JAK2 Inhibitor (JAK2i)

Primary Myelofibrosis Clinical Trial

Official title:
A Multicenter, Open-Label, Phase 1 Study of AJ1-11095 Administered as Oral Monotherapy in Patients With Primary Myelofibrosis (PMF), Post-Polycythemia Vera Myelofibrosis (PPV-MF), or Post-Essential Thrombocythemia Myelofibrosis (PET-MF) Who Have Been Failed by a Type I JAK2 Inhibitor (JAK2i)

Clinical Trial Summary

AJX-101 is a first-in-human (FIH), phase 1, non-randomized, multi-center, open-label clinical trial designed to investigate the safety, tolerability, pharmacokinetics (PK), clinical activity and changes in biomarkers of an orally administered type II JAK2 inhibitor, AJ1-11095, in subjects with primary or secondary myelofibrosis previously treated with at least one type I JAK2 inhibitor.

Clinical Trial Description

This is a phase 1, non-randomized, open-label study utilizing a 3+3 sequential dose escalation design followed by an expansion phase. The primary objective will be to evaluate the safety and tolerability of AJ1-11095, and establish a Maximally Tolerated Dose (MTD) and/or inform the establishment of a candidate Recommended Phase 2 dose (RP2D). The RP2D may be the maximally tolerated dose (MTD) or may be a dose below the MTD. The candidate RP2D will be based on AE pattern, PK and biomarker information, in addition to all available safety and efficacy data. Expansion cohorts will be enrolled to gather additional safety and efficacy information and to further refine input for future RP2D discussions. Eligible participants will have PMF, PPV-MF or PET-MF and will have either have relapsed after a response, or be refractory to, at least one prior type I JAK2 inhibitor therapy, either administered as monotherapy or in combination with another drug. ;
