Pancreatic Cancer Collective Research Team:
Exploiting DNA-Repair Gene Mutations in Pancreatic Cancer New Therapies Challenge

Grant Terms
Round 1: November 2018–December 2019
Round 2: 2020–2020

Drugs called PARP inhibitors are being used to treat ovarian cancer by interfering with the processes of cell division that allows tumors to grow. The team is testing these drugs in pancreatic cancer in combination with other drugs that block cellular pathways also involved in DNA repair. It is hoped that together, these therapies will in many cases cause pancreatic tumors to shrink.


Building on recent large-scale sequencing efforts demonstrating deficiencies in DNA repair in pancreatic cancer, the team is evaluating DNA repair inhibitors in pancreatic cancer. While clinical trials of therapy using PARP inhibitors alone have shown modest activity in pancreatic cancer, the team aims to improve upon PARP inhibitor monotherapy by developing strategies that will combine DNA repair–targeted therapies and be effective in patients experiencing PARP inhibitor resistance.

To accomplish this goal, the researchers are first studying three classes of DNA repair-targeted therapies—CHK1, ATR, and PARP inhibitors—as single agents in organoid cultures of patient-derived pancreatic cancer tumors. They are then identifying the most promising combination of DNA repair-targeted therapies and performing drug testing using patient-derived mouse models of pancreatic cancer. Through the organoid and animal model drug sensitivity experiments, the molecular mechanisms of sensitivity and resistance will be analyzed. A goal of these mechanistic studies is to develop biomarkers that can be used in clinical trials to pinpoint the pancreatic cancer patient population most likely to benefit from these therapies.

This team is part of the Pancreatic Cancer Collective, an initiative of the Lustgarten Foundation for Pancreatic Cancer Research and Stand Up To Cancer.

“We believe that DNA repair inhibitors will have particular utility in the treatment of pancreatic cancer. There may be as much as 20 or even 30% of those patients who will respond to these new drugs.”

Stand Up To Cancer’s research projects are designed to foster collaborative, swift translational research. The hallmarks of these efforts include rigorous application and selection procedures, sufficient funding to allow scientists to focus on the objectives of the grant, and reviews by senior scientists every six months. These reviews help the investigators capitalize on the latest findings, address potential roadblocks, and collaboratively evolve as the science requires.

This team started its work in November 2018; links to publications will be posted when they are available.


Cancer clinical trials allow researchers to study innovative and potentially life-saving new treatments. The goal is to find treatments that are better than what’s currently available, in fact the therapies offered to today’s cancer patients were almost all studied and made possible by people participating in clinical trials. But many cancer clinical trials don’t get completed because not enough people participate.

At StandUpToCancer.org/ClinicalTrials, you’ll find information and answers to common questions about clinical trials. Learn more and talk to your doctor to see if a clinical trial may be the best choice for you.

You can also connect with EmergingMed, a free and confidential clinical trial matching service that provides access to a vast database to help you identify the clinical trials that might be right for you or your loved one.
