In a groundbreaking clinical trial, researchers at Memorial Sloan Kettering Cancer Center have shown promising results in treating pancreatic cancer using a personalized mRNA vaccine along with standard therapies. One participant, Barbara Brigham, was diagnosed with early-stage pancreatic cancer in 2020 after a routine scan. With a desire for more time to spend with her family and after the loss of her husband, she decided to enter the trial, which aims to harness the immune system in combating this notoriously difficult cancer.

Understanding Brigham’s Diagnosis and Treatment Journey
In 2020, Barbara Brigham received an unexpected diagnosis of early-stage pancreatic cancer during a routine scan, a life-altering moment that thrust her into a battle against a particularly aggressive form of the disease. She first visited Memorial Sloan Kettering Cancer Center when diagnosed with a non-cancerous cyst. However, her annual follow-ups became crucial because the subsequent scan revealed cancerous changes. This diagnosis was grim, especially since pancreatic cancer is known for its low survival rates — with studies suggesting that only about ten percent of patients survive more than five years post-diagnosis.
Following the diagnosis, she met with her care team, including surgical oncologist Dr. Vinod Balachandran, who outlined various treatment options. An advocate of innovation, Dr. Balachandran presented the possibility of participating in a clinical trial that combined traditional surgery and chemotherapy with a novel mRNA vaccine tailored specifically to her tumor’s genetic makeup. Brigham’s immediate reaction was influenced by the recent passing of her husband and her desire to live longer for her three children and growing family. The decision to participate was influenced further by a heartfelt conversation with her son, who encouraged her to pursue this opportunity.
The Role of mRNA Vaccines in Cancer Treatment
The foundation of the clinical trial is rooted in the concept of leveraging the body’s immune system to recognize and fight cancer. Traditional therapies like surgery and chemotherapy often fall short, as they treat cancer but do not equip the immune system with the ability to combat the disease effectively. The innovative part of this trial involved an mRNA vaccine developed by BioNTech, a biotechnology company that collaborates with Memorial Sloan Kettering, which creates a personalized vaccine based on the genetic mutations found in each patient’s tumor.
This vaccine is designed to help the immune system identify and target the unique mutations associated with pancreatic cancer. By doing so, it seeks to “teach” the immune system to recognize these cancerous cells as threats. Previous research had shown that long-term survivors of pancreatic cancer often exhibited a spontaneous immune response against their tumors, prompting researchers to ask if this response could be replicated in others through a tailored approach. The ongoing trial aims to determine if a stronger, more targeted immune response leads to better patient outcomes and longer survival rates.
Insights from the Clinical Trial’s Findings
The early results from the trial are promising. Among the sixteen participants, eight demonstrated a ‘strong immune response’ to the vaccine, a critical factor that researchers believe correlates with longer survival without the recurrence of cancer. Notably, those individuals who underwent surgery without the removal of their spleen had better outcomes, which sparked discussions about the critical role of the spleen in immune function.
After 18 months of follow-up, none of the eight patients with a robust immune response experienced a recurrence of cancer. In contrast, the majority of the non-responders had their cancer return within a much shorter period. Further study, published in a leading medical journal, suggested that patients who had a strong immune response continued to fare better three years post-treatment, a notable achievement in the context of pancreatic cancer, where the average survival after diagnosis is typically only three to three-and-a-half years.
The Future of mRNA Vaccines in Oncology
The promising data emerging from this trial highlights the potential of mRNA vaccines in oncology not just for pancreatic cancer, but possibly for a variety of other cancer types. Researchers argue that the adaptability of mRNA technology can lead to more tailored therapies that target the unique genetic makeup of each patient’s tumor. However, Dr. Balachandran emphasizes that further research is essential to determine the efficacy of this approach on a larger scale, particularly concerning factors affecting immune response like organ health.
A new phase of research is set to begin, focusing on early-stage pancreatic cancer patients to confirm whether a healthier spleen enhances vaccine effectiveness. In addition to pancreatic cancer, ongoing efforts are examining the role of mRNA vaccines in treating other challenging cancers like melanoma, digestive system cancers, and more, making this a rapidly evolving field of study in cancer therapy.
Personal Impact: Brigham’s Journey Beyond Cancer
For Barbara Brigham, participating in this clinical trial has not only extended her life beyond initial projections, but has also granted her the opportunity to enjoy significant family milestones. Over four years post-diagnosis, she welcomed her eighth grandchild into the world and celebrated her brother’s 60th wedding anniversary. These moments would have been lost, she acknowledges, without the possibility the trial provided.
Despite the challenges of living with diabetes due to the partial removal of her pancreas, she describes the trial as a “wondrous thing” that transformed her perspective on life. Brigham’s story is emblematic of a success that shines amidst a complex disease landscape, representing hope that personalized medicine can bring to those facing similar battles.

Frequently Asked Questions
Question: What is pancreatic cancer?
Pancreatic cancer is a type of cancer that starts in the pancreas, an organ that lies behind the stomach and helps with digestion. It is often diagnosed at an advanced stage and has a low survival rate compared to other cancers.
Question: How do mRNA vaccines work in cancer treatment?
mRNA vaccines work by introducing a piece of genetic material that instructs cells to produce a protein similar to those found on cancer cells. This activates the immune system to recognize and attack cancer cells more effectively.
Question: What are some potential side effects of participating in a clinical trial?
Participants in clinical trials may experience side effects ranging from minor symptoms like fatigue to more significant reactions depending on the treatment approach, underlying health, and individual responses to the experimental therapies involved.
