First US clinical trial of PCLX-001 set to start in Acute Myeloid Leukemia (AML).
Edmonton, Alberta, Canada, November 2, 2022 Pacylex, a clinical-stage NMT inhibitor company developing first-in-class therapies for leukemia, lymphoma, and solid tumor cancers, today announced that the U.S. Food and Drug Administration (FDA) has cleared the Investigational New Drug (IND) application for PCLX-001 for the treatment of acute myeloid leukemia (AML). The open IND enables a Phase 1/2 clinical study to start in the coming months at The University of Texas MD Anderson Cancer Center, which was recently awarded a US Department of Defense (DOD) grant for this purpose.
Last month the U.S. FDA also granted PCLX-001 Orphan Drug Designation for “treatment of patients with acute myeloid leukemia.” PCLX-001 is a first-in-class N-myristoylation inhibitor in clinical development by Pacylex. PCLX-001 is currently being studied in non-Hodgkin lymphoma (NHL) and solid tumor cancer patients at 4 sites in Canada. Pacylex has the first and only NMT inhibitor in clinical studies.
“With this IND clearance, Pacylex opens up a second clinical indication for the investigation of PCLX-001 in patients,” said Michael Weickert, PhD, CEO of Pacylex. In the ongoing studies of PCLX-001, seventeen patients have been accrued through 5 dose levels of oral, once-per-day PCLX-001 with no dose limiting toxicities observed.
“Non clinical data suggests that AML may be the cancer type most sensitive to NMT inhibitors, so we are excited to move PCLX-001 into clinical studies in AML patients in the near future,” said John Mackey, MD, CMO of Pacylex. Luc Berthiaume, PhD, CSO of Pacylex commented, “It is gratifying to see the pre-clinical work pioneered in my lab, translating to clinical investigations and the potential to help patients in the near future.” Data on the scientific rationale for PCLX-001 in AML patients, will be presented at the American Society of Hematology (ASH) Annual Meeting and Exposition from 10-13 December 2022.
The ongoing clinical PCLX-001 trial in NHL and solid tumor patients is registered at ClinicalTrials.gov Identifier: NCT04836195.
PCLX-001 (aka DDD86481) is a first-in-class, small molecule NMT inhibitor originally developed by the University of Dundee Drug Discovery Unit as part of a program to treat African sleeping sickness, funded by Welcome Trust. Pacylex is developing PCLX-001 in the form of a once-a-day pill initially to treat leukemia and lymphoma. PCLX-001 has also been shown to inhibit the growth of lung and breast cancer tumors in animal models. In leukemia, lymphoma and breast cancer patients, the levels of NMT2 are correlated with survival, suggesting an important biological role in these cancers.
Pacylex is a pharmaceutical company headquartered in Edmonton, Alberta, Canada, targeting hematologic and solid cancers with a new first-in-class therapeutic, PCLX-001. Pacylex’s technology combines new insights from Dr. Luc Berthiaume of the University of Alberta connecting myristoylation to cancer with a family of high quality myristoylation inhibitors Pacylex licensed from the University of Dundee. PCLX-001 is the lead drug in a new class of NMT inhibitors, enabling Pacylex to exploit NMTs as new clinical targets for cancer treatment. Pacylex initiated clinical studies in Canada in the fall of 2021 in non-Hodgkin lymphoma and solid tumors. Pacylex is also receiving support from an Alberta Innovates AICE grant in 2020, and the research leading to this breakthrough was supported in part by the Alberta Cancer Foundation and the Cure Cancer Foundation. The US Department of Defense is supporting the initial clinical investigation of PCLX-001 in AML patients.
