IPIAD: An Augmentation to Standard Treatment of PDAC Using Five Repurposed Drugs


“This paper presents the rationale for adding five already approved and marketed generic drugs from general medical practice to the current standard current first line chemotherapy for pancreatic ductal adenocarcinoma (PDAC).”

BUFFALO, NY - February 9, 2024 – A new research perspective was recently published in Oncoscience (Volume 11) on February 7, 2024, entitled, “IPIAD- an augmentation regimen added to standard treatment of pancreatic ductal adenocarcinoma using already-marketed repurposed drugs irbesartan, pyrimethamine, itraconazole, azithromycin, and dapsone.”

In this new paper, researcher Richard E. Kast from IIAIGC Study Center presents the data and rationale for adding five generic non-oncology drugs from general medical practice to gemcitabine, nab-paclitaxel, a current standard cytotoxic chemotherapy of pancreatic ductal adenocarcinoma. The regimen, called IPIAD, uses an angiotensin receptor blocker (ARB) irbesartan indicated for treating hypertension, an old antimicrobial drug pyrimethamine indicated for treating toxoplasmosis or malaria, an old antifungal drug itraconazole, an old broad spectrum antibiotic azithromycin, and an old antibiotic dapsone.

“In reviewing selected growth driving systems active in pancreatic ductal adenocarcinoma then comparing these with detailed data on ancillary attributes of the IPIAD drugs, one can predict clinical benefit and slowing growth of pancreatic ductal adenocarcinoma by this augmentation regimen.”
