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.
Detailed 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.
Criteria for eligibility:
Criteria:
Inclusion Criteria:
1. 18 years of age or older.

6. ECOG PS of 0, 1, 2, or 3.
7. Prior therapy with at least 1 type I JAK2 inhibitor, and either failed to achieve a
response or relapsed after achieving a response.
8. ANC ≥1.0×10^9/L.
9. Platelet count ≥75×10^9/L.

8. Use of erythropoiesis stimulating agents (unless stable for >8 weeks).
9. Peripheral neuropathy ≥ Grade 2 (NCI CTCAE v 5.0).
10. Unable or unwilling to undergo CT or MRI for spleen size imaging.
11. Pregnant or breastfeeding.
12. Requirement for therapy with a medication that is a strong CYP3A4 inhibitor as a
concomitant medication.
