The new award will fund investigation into a method for turning a tumor survival mechanism into a Trojan Horse

Cosimo Commisso, PhD, was awarded a one-year, $110,000 Lustgarten Foundation grant to support his lab’s pancreatic cancer research. The award is part of the foundation’s August 2026 announcement of $22.8 million in new research funding in fiscal year 2026.

The Lustgarten Foundation’s support will aid the Commisso lab’s study of how pancreatic cancer adapts as nearby nutrients vanish. Because they expand quickly, pancreatic tumors demand more energy and other resources than they can acquire from nearby blood vessels.

Rather than limiting their growth to more sustainable rates, these cancer cells adapt by finding alternative ways to scavenge what they need. One scrounging strategy prevalent in pancreatic cancer involves cancer cells reshaping their cell surfaces to snatch extra nutrients from the jelly-like substance between cells or extracellular matrix.

This cellular contortion is a process called macropinocytosis. In previous research, Commisso has shown that blocking it cuts tumors off from needed energy and protein building blocks. This, in turn, suppresses tumor growth by essentially starving the tumor.

The new funding will support the lab’s effort to flip the script on this strategy. Instead of blocking macropinocytosis, the scientists will test turning up the knob on a tumor’s voracious appetite for scavenging to cause it to self-destruct from overconsumption. This approach also may be able to force cancer cells to take in more chemotherapeutic molecules, which can struggle to penetrate the dense and fibrotic tumor microenvironment.

“This project has the potential to turn one of pancreatic cancer’s greatest survival tools into a Trojan Horse,” said Commisso.

“Support from organizations like the Lustgarten Foundation encourages us to ask fundamentally new questions in the pursuit of better therapies.”

With the fiscal year 2026 awards, the Lustgarten Foundation has invested $333 million in pancreatic cancer research across 386 projects at 86 academic institutions since 1998. As the world’s largest private funder of pancreatic cancer research, the foundation drives scientific breakthroughs that are redefining what is possible for patients and bringing the field closer than ever to the goal of transforming pancreatic cancer into a curable disease.

From the Lab to the Clinic: Graduate Student Helps Advance Promising Pancreatic Cancer Therapy

When Patrick Hagan joined Sanford Burnham Prebys as a graduate student, he hoped his research would one day help patients. Today, he is helping research that could translate more than a decade of scientific discovery into a potential new treatment for one of the deadliest forms of cancer.

Hagan, a PhD candidate in the laboratory of Nicholas Cosford, PhD, recently received the top award from the San Diego chapter of Nucleate, a nonprofit organization that helps scientists translate promising discoveries into real-world solutions.

Through the six-month accelerator program, Hagan developed ATG Attack, a venture focused on advancing autophagy inhibitors for pancreatic cancer. The project also received a Biocom Golden Membership at Nucleate San Diego’s Demo Day, recognizing both the scientific promise of the work and its potential to improve outcomes for patients.

“Ultimately, the goal is to improve outcomes for cancer patients,” said Hagan. “That’s why I went to graduate school.”

The project builds on more than 10 years of collaboration between Cosford and director of the Salk Cancer Center, Reuben Shaw, PhD. Together, the teams have been developing compounds that inhibit autophagy, a cellular recycling process that many cancer cells depend on for survival.

“Autophagy is one of the ways cancer cells gain resistance to standard therapies,” Hagan explained. “We’ve reached a point where we believe these compounds have the potential to make it all the way to patients.”

The team’s initial focus is pancreatic cancer, a disease with one of the lowest survival rates among major cancers. Many pancreatic tumors are driven by mutations in the KRAS gene and rely heavily on autophagy. In preclinical studies, the researchers have shown that blocking this process can shrink tumors and enhance the effectiveness of existing treatments.

The experience also reinforced the value of Sanford Burnham Prebys’ translational research environment.

Hagan credits Cosford and colleagues throughout the Institute, including members of the Center for Therapeutics Discovery and its Conrad Prebys Center for Chemical Genomics, with helping shape his approach to drug discovery.

“I’ve been fortunate to work with scientists who are deeply focused on translating discoveries into therapies,” he said. “Our lab operates almost like a small pharmaceutical company. We have chemists creating compounds, biologists testing them and researchers evaluating how they perform in disease models. Everything is focused on moving promising discoveries closer to patients.”

For Hagan, however, the motivation remains personal.

He keeps a Post-it note on his laptop bearing the names of two researchers he knew who died from cancer at a young age. It serves as a daily reminder of why the work matters.

“Research can feel like a series of very small steps,” he said. “But every experiment, every paper and every collaboration has the potential to move the field forward. If something we do helps another scientist, attracts a new partner or ultimately helps a patient, then it’s worth it.”

For Hagan, those small steps are all part of a larger goal: bringing new hope to patients facing pancreatic cancer.

Eleven participants completed six weeks of hands-on biomedical research at Sanford Burnham Prebys

Sanford Burnham Prebys Medical Discovery Institute welcomed its fifth cohort of interns this year for the Summer Program to Accelerate Regenerative Medicine Knowledge (SPARK). SPARK is an initiative by the California Institute for Regenerative Medicine (CIRM) that provides research opportunities for high schoolers from underrepresented groups throughout California.

The SPARK participants completed six-week internships at Sanford Burnham Prebys and completed projects under the supervision of their faculty mentors.

“My experience was amazing right from the get-go,” said Jonathan Wang, a rising senior who worked in the lab of Shengjie Feng, PhD. “The whole lab came to greet me on my first day and it was really inviting.”

“It was all very new to me as both my first research experience and my first internship,” said Tannishtha Dhar, a rising junior who worked in the lab of Kelly Kersten, PhD. “I’ve always wanted to be a clinician or surgeon, but now I have a growing interest in biomedical research as well.”

In the first of two capstone events, the interns delivered poster presentations at the Sanford Burnham Prebys campus on July 30, 2026. The students detailed their projects and what they had learned over the course of their internships.

“Beyond what I learned about progressive liver disease in my project, I’m walking away with a greater appreciation of the importance of communication,” said Shiva Ambatipudi, a rising junior who worked in the lab of Debanjan Dhar, PhD. “With lab meetings every week, I saw how valuable it was to be able to share the results of your experiments and make connections with each team member’s work.”

The SPARK internship culminated with CIRM’s annual SPARK conference at the University of California Berkeley from July 31 to August 1, 2026. The participants from Sanford Burnham Prebys presented their work and networked with more than 110 interns from other institutions across the state.

“Being a part of the CIRM symposium was a great way to become more confident in your skills as a scientist,” said Rishab Ghosh, a rising junior who worked in the lab of Timothy Huang, PhD. “I think that growing your personal network and learning how to collaborate with other researchers also are very important aspects of this program.”

“I’m simply blown away at the quality of the work completed by these SPARK interns over six weeks,” said SPARK program director Sanjeev Ranade, PhD. “It was incredibly rewarding to help guide these bright, curious and ambitious students.”

Members of the next generation of biomedical researchers and health care professionals spent three weeks training at Sanford Burnham Prebys

On Friday, July 24, 2026, the Sanford Burnham Prebys Medical Discovery Institute community celebrated the contributions of five high school student interns from the Preuss School. Located on the University of California San Diego campus in La Jolla, the Preuss School educates students striving to be first-generation college graduates.

Participants in the Preuss summer internship program gained valuable hands-on research experience over three weeks. This program is generously funded by Debby and Wain Fishburn.

“For many high school students, biomedical research is something very new to them,” said Yuk-Lap (Kevin) Yip, PhD, associate director of training and education in the NCI-designated Cancer Center at Sanford Burnham Prebys, during the July 24 capstone presentation.

“Over the summer, our five outstanding interns gained hands-on experience as scientists and began to understand why we are so excited about the work we do.”

Graduate student Joshua Minyard introduced the interns and invited them to discuss why they wanted to participate in the program.

“I was looking to test the waters for a potential future career in biomedical research,” said intern Derek Arista.

“I thought this would be a great opportunity to work in a laboratory and deepen my knowledge as I’m considering going into the medical field,” said intern Hailey Villa.

The interns then presented the findings from their three weeks of conducting experiments. In addition to sharing how cancerous tumors in different tissues affected fruit flies, the interns also detailed what they learned about drug discovery research.

“We worked with our mentor Josh Minyard to target a protein called STK4 that is known for allowing leukemia cells to survive,” said intern Eliud Tapia.

The interns tested three different drugs as potential inhibitors of STK4. They found that one of the three was the most successful inhibitor and was effective at lower concentrations.

Katya Marchetti, a graduate student and scientific leader of the 2025 and 2026 Pruess internship programs, provided closing remarks following the interns’ capstone presentation.

“I chose to commit to running this program because eight years ago, almost to the day, I was in these interns’ shoes,” said Marchetti. “I was a high school student participating in the summer research program that completely changed the trajectory of my life.

“You should be incredibly proud of what you’ve accomplished, not just because of the data that you’ve collected, but because of how much you’ve grown. Whether or not you decide to stay in science or pursue something completely different, I hope you know that you are capable of doing hard things, because you just proved it.”

The Preuss summer internship program at Sanford Burnham Prebys has operated since 2009 and is jointly organized by the NCI-designated Cancer Center and Office of Learning and Development. This program’s founding was supported by donors Peggy and Peter Preuss, and Debby and Wain Fishburn.
