Is Combination Therapy Here for MPN? (SOHO 2025) - "2 Outside of the potential benefit of type 2 (AJ1-11095) and JAK2 V617F-selective (INCB160058) inhibitors under phase 1 evaluation, the research community has focused efforts on developing rational JAK inhibitor-based combination therapy regimens...3 Data from prospective and retrospective studies suggest a correlation between spleen reduction and OS with ruxolitinib and pacritinib...Nevertheless, the combination of pelabresib and ruxolitinib was well tolerated, and biomarkers of disease modification — including reduction in bone marrow fibrosis, driver mutation allele frequency, and inflammatory cytokine expression levels — all favored the combination, supporting the proposed mechanism of action and published preclinical synergy...11 The phase 3 trial will aim to confirm this activity in patients who have received at least 18 weeks of ruxolitinib therapy and meet rigorously defined criteria for suboptimal response, after which these patients will be randomized to..."

Ajax Therapeutics and Schrödinger Expand Research Collaboration to Include Additional JAK Target (Businesswire) - "Ajax Therapeutics, Inc. and Schrödinger, Inc...announced an expansion of their exclusive research collaboration to include a new Janus kinase (JAK) target. The partnership was established in 2019 with a goal of leveraging Schrödinger’s advanced computational platform and Ajax’s structural biology insights to develop a pipeline of novel molecules, with a focus on JAK inhibitors. Ajax’s lead candidate from the collaboration, AJ1-11095, is a potential first-in-class Type II JAK2 inhibitor currently being evaluated in a Phase 1 clinical study for the treatment of myelofibrosis....Under the terms of the amended agreement, Ajax and Schrödinger will collaborate on the discovery of the development candidate, and Ajax will be responsible for clinical development and commercialization."

A Multicenter, Open-Label, Phase 1 Clinical Trial 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) (ASH 2024) - P1 | "MF-directed therapy must be stopped at least 5 half-lives (5 days for hydroxyurea) before start of AJ1-11095. A Study May Proceed letter was received from the US Food and Drug Administration in May 2024. We expect to enroll the first patient in this trial September of 2024 and to activate approximately 10 sites in the US, with inclusion of sites outside the US in the dose expansion stage for a total of ~76 subjects across both stages."
