Official title
A Combined Phase 1/2 Study to Investigate the Safety, Pharmacokinetics, Pharmacodynamics, and Clinical Activity of TP-0903 in Patients With Previously Treated Chronic Lymphocytic Leukemia (CLL)
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
TP-0903 is an inhibitor of AXL kinase. TP-0903 has shown potent inhibition of AXL kinase and other TAM family members in a biochemical kinase assay. TP-0903 demonstrates corresponding activity in cancer cell lines and mouse xenograft efficacy models. TP-0903 is shown to block cancer cell epithelial-to-mesenchymal transitions. AXL was identified as a potential therapeutic target in chronic lymphocytic leukemia (CLL). TP 0903 was shown to induce apoptosis in CLL B-cells taken directly from patients.TP-0903 was equally potent against CLL cells regardless of risk-factor. TP-0903 is a novel oral inhibitor that targets AXL kinase and reverses the mesenchymal phenotype associated with advanced cancers. TP-0903 has demonstrated profound single agent activity in CLL B cells taken directly from patients even if the patient has high risk factors (ie, 17p/P53 deletions) or progressed on other agents (ie, ibrutinib). TP-0903 is currently being evaluated in patients with refractory solid tumors (TP-0903-101). This proposed study is designed to identify the maximum tolerated dose (MTD), safety profile and recommended Phase 2 dose (RP2D) of TP-0903 in patients with previously treated CLL. Treatment cycles may be repeated if the patient continues to show benefit and if TP-0903 is reasonably well tolerated. The study will investigate the safety, pharmacokinetics, pharmacodynamics, and clinical activity of TP-0903.
