About zelenirstat (PCLX-001) Zelenirstat (formerly identified as PCLX-001) is a first-in-class, oral, small molecule N-myristoyltransferase (NMT) inhibitor being developed to treat patients with leukemia, lymphoma, and solid tumors. In animal models, zelenirstat selectively killed cancer cells in vitro and has been shown to regress hematologic malignancies and inhibit the growth of lung and breast cancer tumors. In AML models, zelenirstat killed leukemic stem enriched cell populations and allowed the regeneration and growth of normal bone marrow cells. About zelenirstat Phase 1 and 2 studies Pacylex completed the dose escalation phase of a Phase 1 multiple ascending dose safety, tolerability, and pharmacokinetics study on zelenirstat in R/R lymphoma and solid tumor patients (NCT04836195). A recommended Phase 2 dose was determined. Zelenirstat demonstrated an acceptable safety and tolerability profile, pharmacokinetics consistent with once daily oral dosing, and early signs of potential efficacy. Zelenirstat is currently being studied in a Phase 2a open-label study designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and clinical activity of zelenirstat in patients with R/R B-cell non-Hodgkin Lymphoma (NHL). A separate Phase 2a cohort is planned in advanced solid malignancies who have progressed on all available standard therapies.
