Descriptive Information

• Brief Title: Actuate 1901: 9-ING-41 in Myelofibrosis
• Official Title: Phase 2 Study of 9-ING-41, a Glycogen Synthase Kinase 3 Beta (GSK 3β) Inhibitor, as a Single Agent or Combined With Ruxolitinib, in Patients With Myelofibrosis
• Brief Summary: 9-ING-41 has anti-cancer clinical activity while not causing myelosuppression, and has both pre-clinical anti-fibrotic activity and activity against myelofibrosis. This Phase 2 study will study its efficacy in patients with advanced myelofibrosis.
• Detailed Description: 9-ING-41 is a first-in-class, intravenously administered, maleimide-based, small molecule, potent selective GSK-3β inhibitor with significant pre-clinical and clinical anticancer activity. In the ongoing Actuate 1801 study in a cohort of over 90 patients with advanced refractory malignancies, 9-ING-41 has exhibited no significant toxicity, including no myelosuppression, and significant anti-tumor activity. 9-ING-41 also has significant pre-clinical ability to reverse pathologic fibrosis in multiple models of pulmonary and pleural fibrosis. Reversal of fibrosis by an anti-fibrotic agent in patients with advanced myelofibrosis (MF) has recently been demonstrated to be of clinical benefit. 9-ING-41 has the potential to act both as an anti-neoplastic agent (without causing myelosuppression) and an anti-fibrotic agent in patients with MF. The efficacy of Ruxolitinib is limited in many patients by the inability to tolerate adequate doses for an adequate duration with myelosuppression being a frequent dose limiting toxicity. 9-ING-41 may reduce the dose of Ruxolitinib needed for optimal therapeutic response and/or reverse myelosuppression so than an adequate dose of Ruxolitinib can be tolerated. Pre-clinical data show synergy in MF between 9-ING-41 and Ruxolitinib. This Phase 2 study is designed to evaluate the efficacy of 9-ING-41, as a single agent or in combination with Ruxolitinib, in patients with advanced, poor prognosis MF.
