Pacylex Pharmaceuticals Inc.

Pacylex Pharmaceuticals is a clinical stage oncology company pioneering a new class of anti-cancer compounds, NMT inhibitors. Pacylex is developing oral zelenirstat, the first in class NMTi, for heme cancers (Phase 1/2 study in acute myeloid leukemia patients (NCT06613217), Orphan and Fast Track Designations) with PR and CRs in DLBCL and AML, and for solid tumors as:

  1. ADC payload - recent data showed the potency of an ADC with zelenirstat was over 20-1,000x the potency of zelenirstat itself against prostate and breast cancer cell lines including a breast cancer line resistant to other ADCs.
  2. Synergy with immune checkpoint inhibitors (ICIs) like Keytruda, to overcome tumor resistance to ICIs. Recent animal data showed synergy between zelenirstat and anti-PD-1 in an ICI resistant head and neck cancer model, and the mechanism is understood. A Phase 2 clinical study is ready to go.
  3. Zelenirstat is the most potent radiosensitizer. A Phase 2 clinical study in glioblastoma patients is ready to go.
