Propanc Biopharma Reports Data Showing 90% Tumor Growth Inhibition with PRP in Pancreatic Cancer Models, Contrasting Profile with Revolution Medicines’ Daraxonrasib
Propanc Biopharma highlighted new preclinical data for its lead candidate PRP in pancreatic ductal adenocarcinoma, showing greater than 90% mean tumor growth inhibition versus vehicle (p < 0.001) and a median overall survival extension of more than 2.5-fold versus controls in animal models.
PRP also reduced liver and peritoneal metastases, remodeled the tumor microenvironment, and re-sensitized chemo-resistant PDAC cells to gemcitabine plus nab-paclitaxel. Unlike newly FDA-approved daraxonrasib (Revolution Medicines), PRP targets EMT, cancer stem cells, and fibrosis rather than RAS signaling, and is not RAS-genotype restricted.
The company plans a multicenter Phase 1b first-in-human study of PRP in Q1 2027, enrolling up to 50 patients with advanced solid tumors at Australian sites. CEO James Nathanielsz positioned PRP as a potential combination or sequential partner to RAS inhibitors rather than a substitute.
