Pharmaxis Targets Myelofibrosis in New Clinical Trial

Pharmaxis is advancing a 6-month Phase 2 clinical trial of a new drug (PXS-5505) targeting the rare bone cancer myelofibrosis (MF).

PXS-5505 is an anti‐fibrotic pan-Lysyl Oxidase (pan-LOX) inhibitor that has completed long-term toxicity studies and Phase 1a and 1b clinical trials demonstrating a well-tolerated drug that effectively inhibits all enzymes in the lysyl oxidase family that are involved in fibrosis.

Myelofibrosis is a cancer with a poor prognosis and limited therapeutic options. Pharmaxis believes that the current treatments can be augmented by use of a pan-LOX inhibitor and be disease modifying in a market that is conservatively worth US$1 billion per annum.

PXS-5505 was granted Orphan Drug Designation by the US Food and Drug Administration (FDA) in July 2020. Read the media release.

In August 2020 the FDA completed a review of the company’s Investigational New Drug (IND) application for PXS-5505 and gave Pharmaxis the green light to proceed with a phase 1c/2a clinical trial for the treatment of myelofibrosis in adults.  The clinical trial protocol incorporates a one-month dose escalation phase followed by six months’ treatment in an open label study of patients who are not on a JAK inhibitor. The first patient was enrolled in Q1 2021 and the study is expected to conclude in 2022. Read the media release.

A study published by researchers at Boston University School of Medicine has found that the two Pharmaxis drug discoveries PXS-LOX_1 and PXS-LOX_2 are showing promising early results in slowing disease progression in primary myelofibrosis (PMF).
