Could diet modification make chemotherapy drugs more effective for patients with pancreatic cancer? Laboratory experiments, testing a ketogenic diet, lead to nationwide clinical trial —


The findings of a brand new research recommend {that a} ketogenic weight-reduction plan — which is low in carbohydrates and protein, however excessive in fats — helps to kill pancreatic most cancers cells when mixed with a triple-drug remedy developed by the Translational Genomics Analysis Institute (TGen), an affiliate of Metropolis of Hope.

In laboratory experiments, the ketogenic weight-reduction plan decreased glucose (sugar) ranges within the tumor, suggesting the weight-reduction plan helped starve the most cancers. As well as, this weight-reduction plan elevated ketone our bodies produced by the liver, which put further stress on the most cancers cells. The research revealed within the journal Med.

By destabilizing the most cancers cells, the ketogenic weight-reduction plan created a microenvironment through which the triple-drug remedy designed by TGen — a mix of gemcitabine, nab-paclitaxel and cisplatin — was simpler at knocking out the tumor, in accordance with the research.

“By limiting glucose availability, the ketogenic weight-reduction plan could promote chemotherapy efficacy,” stated TGen Distinguished Professor Daniel D. Von Hoff, M.D., thought of one of many nation’s foremost authorities on pancreatic most cancers. Dr. Von Hoff is without doubt one of the research authors and designers of the remedy.

As well as, the ketogenic weight-reduction plan was proven to have a positive affect on antitumor immunity by inducing pro-inflammatory tumor gene expression, which additional weakened the most cancers.

Scientific trials at 5 areas

To check these laboratory findings, researchers initiated a scientific trial of as much as 40 sufferers at 5 facilities nationwide: HonorHealth in Scottsdale, USC in Los Angeles, Nuvance Well being in Connecticut, Atlantic Well being System in New Jersey, and South Texas Accelerated Analysis Therapeutics in San Antonio.

The scientific trial will take a look at whether or not including a ketogenic weight-reduction plan to the triple-drug remedy will improve total survival in sufferers with pancreatic most cancers. This scientific trial started in late 2020 and is anticipated to proceed to accrue sufferers via June 2023. Sufferers will probably be randomly assigned to both obtain the triple-drug routine whereas on a typical weight-reduction plan, whereas the opposite half will obtain a ketogenic weight-reduction plan and the triple-drug remedy. The dietary elements of the research are being rigorously monitored.

“Our laboratory experiments present {that a} ketogenic weight-reduction plan adjustments pancreatic most cancers metabolism and its response to chemotherapy,” stated Haiyong Han, Ph.D., a Professor in TGen’s Molecular Drugs Division, and one of many research authors and a designer of the research’s experiments.

Additionally contributing to this research have been: Princeton College, Salk Institute for Organic Research, Rutgers Most cancers Institute and Rutgers Robert Wooden Johnson Medical Faculty, the Chinese language Academy of Sciences, and the Ludwig Institute for Most cancers Analysis.

The preclinical research was funded by: Stand As much as Most cancers (SU2C), the Nationwide Institutes of Well being, Ludwig Most cancers Analysis, the New Jersey Fee on Most cancers Analysis, New Jersey Well being Basis, a Rutgers Busch Biomedical Grant, the Lustgarten Basis, the Don and Lorraine Freeberg Basis, and the David C. Copley Basis.

The scientific trial is being funded by the Purple Pansies and the John E. Sabga Basis.
