Our sensitivity biomarker is found in 19 types of cancer at a prevalence (by type).
We show that NMT2 expression is lost in numerous cancers.



Pacylex: Targeting myristoylation to selectively kill cancer.

Pacylex Pharmaceuticals, Inc. is developing a precision medicine solution for multiple common cancers. Our approach exploits a previously-unknown therapeutic target in cancer, a cellular process termed myristoylation, which is an essential process allowing many signaling proteins to propagate signals across cell membranes. Our initial indications of interest are blood cancers including leukemia and lymphoma to be followed by numerous solid tumour types. Our drug, PCLX-001, is a first-in-kind therapy.

Our diagnostic technology identifies those patients who will benefit from our drug, sparing many patients needless treatment. We are able to do this through our discovery that a subset of patients across many cancer types have lost one of the two proteins required for myristoylation, N-myristoyl transferase 2 (NMT2). This protein loss presents a therapeutic opportunity for our drug candidate, PCLX-001.

New Driver Biology

NMT2 Loss

NMT2 expression is lost in numerous cancers. The prevalence of the loss reaches 70- 82% in several leukemias and lymphomas. This NMT2 loss appears to promote tumorigenesis but also exposes an Achilles heel that allows new treatment strategies.

Orally bioavailable small molecule


Our drug is an orally bio-available small molecule that is optimized for NMT inhibition. PCLX-001 has promising attributes of a one pill per day dose strategy and has been shown to be active across many cancer types.

19 Cancer types

Sensitivity Biomarker

We find 19 types of cancer have our sensitivity biomarker,at a prevalence of 5% to 80% of individual cancers. Sensitivity biomarkers are more common in blood and immune system cancers.

Targeting Urgent Needs

Despite major advances in cancer care, many patients don’t survive long after their diagnosis. Fewer than one third of patients diagnosed with lung cancer or acute myeloid leukemia survive for 5 years. Our lead cancer drug eliminates leukemia and lymphoma tumors and inhibits lung and breast cancer tumors in many animal models including with drug resistant patient tumor tissue. We are working now to bring this new medicine to human clinical studies.

Our Story

Dr. Luc Berthiaume’s team at the  University of Alberta (U of A) showed that many human cancers lose a protein needed to keep growth and proliferation in check. These cells then become very sensitive to low dose NMT inhibitor treatments while normal tissues are unaffected. This discovery triggered the creation of a U of A spinoff company, Pacylex Pharmaceuticals Inc., to commercialize a diagnostic test to identify patients with NMT inhibitor sensitive cancers.

Independently, the University of Dundee Drug Discovery program developed NMT inhibitors to treat parasitic infections.   Pacylex then in-licensed the rights to Dundee's panel of drug candidates - our lead compound is called PCLX-001. By combining Pacylex’s diagnostic test with the Dundee drug, we have a precision medicine approach to selectively treat patients with cancers sensitive to PCLX-001.

Pacylex is developing

We have demonstrated:

PCLX-001 eradicates established tumours in three lymphoma or leukemia cell line xenograft studies

PCLX-001 achieves tumour regression, comparable to standard-of-care treatment, in solid tumour xenograft studies

Our new synthetic pathway reduces the 13 step synthesis of PCLX-001 to 3 steps with high yield; this new proprietary medicinal chemistry is of broad applicability

Multiple common cancer types have the biomarker for drug sensitivity based on:

  • RNA level data in cells from 19 types of cancer
  • Protein level data in clinical samples from 11 types of cancer (survey ongoing)

Our sensitivity biomarker test performs well in formalin-fixed paraffin-embedded clinical tumour samples, standard methodology in clinical pathology
