On May 29, 2023 Amplia Therapeutics Limited (ASX: ATX) ("Amplia" or the "Company") reported new data showing the efficacy of its investigational FAK inhibitor, AMP945, in a preclinical model of pancreatic cancer, when used in combination with FOLFIRINOX treatment (Press release, Amplia Therapeutics, MAY 29, 2023, View Source [SID1234632170]). FOLFIRINOX, a combination of four chemotherapies used in the treatment of pancreatic cancer patients, is currently a widely-used treatment in many major markets around the world including the US.

New data from preclinical studies conducted in the laboratory of Prof. Paul Timpson at the Garvan Institute of Medical Research in Sydney, demonstrate that mice treated with AMP945 in addition to FOLFIRINOX show improved overall survival compared to those treated with FOLFIRINOX alone. The data, available in the Meeting Abstracts for the forthcoming American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) meeting in Chicago, USA, (here) 1 describe studies in mice bearing pancreatic cancer tumours derived from a human patient. AMP945 was given in the days preceding FOLFIRINOX treatment (given on a 12-day cycle) resulting in a statistically significant increase in survival (up to 35% approx.) compared to FOLFIRINOX-only treated mice.
Dr Chris Burns, Amplia’s CEO and Managing Director commented: "The exciting results from this mouse study further indicate the potential of AMP945 in pancreatic cancer treatment when used in combination with standard-of-care therapies. In light of this data, we have filed a patent to cover the use of FAK inhibitors, and particularly AMP945, in combination with FOLFIRINOX and related treatment regimes."
With this data, and the Company’s previously reported preclinical data demonstrating the benefit of combining AMP945 with gemcitabine and nab-paclitaxel, AMP945 has shown promising activity in models of pancreatic cancer with the two most common first-line chemotherapy regimens for treatment of the disease.
Prof. Nick Pavlakis, a medical oncologist at the Royal North Shore Hospital in Sydney, and an investigator in the current ACCENT trial, commented: "FOLFIRINOX is employed under certain conditions in Australia and more broadly in the USA and Europe, and the data from this study, coupled with the developing safety and tolerability data from Amplia’s current ACCENT trial, provide strong support to undertake a future clinical study of AMP945 with FOLFIRINOX."
