Dr. Vinod Balachandran, the principal investigator of the trial and senior author at MSK, expressed his enthusiasm regarding the effectiveness of this groundbreaking treatment. “Utilizing RNA vaccine technology, we have discovered that we can educate the immune system to identify pancreatic cancer, potentially leading to a lasting immune response that could span over several years,” he explained. “The ability to provoke a strong and durable immune reaction is a crucial aspect of any cancer vaccine.”

As pancreatic cancer presents significant challenges in terms of treatment, Dr. Balachandran was surprised to observe immune responses in some patients. “We are pleased to observe that our method can educate the immune system to recognize pancreatic cancer, demonstrating a potent immune response that could have a positive impact on patients,” he remarked. Nevertheless, he emphasized that while the findings are promising, the vaccines are still in the early phases of testing.
The team is gearing up for a more extensive study to further evaluate these therapeutic cancer vaccines in patients with surgically removable pancreatic cancer. Therapeutic vaccines are designed to target early-stage cancer cases, where tumors are localized and have not metastasized.
Out of the 16 participants involved in the trial, the vaccine triggered an immune response in half of them. Each participant received a personalized cancer vaccine tailored to target specific proteins unique to their form of the disease. Following surgery, the patients also underwent treatment with an immunotherapy drug (atezolizumab) and standard chemotherapy.
These therapeutic cancer vaccines, such as the autogene cevumeran used in the trial, aim to treat existing cancer by training the immune system to identify cancer cells as foreign invaders. Patients who displayed an immune response to the vaccine were more likely to experience a reduced cancer risk at their three-year follow-up.
The goal of the vaccine is to address localized cancer cases where tumors can be surgically removed, aiming to delay or prevent recurrence. Dr. Balachandran highlighted that this approach could potentially be applied to other cancer types as well. “Our latest results support the use of personalized mRNA vaccines to target neoantigens in each patient’s tumor, showing promise for patients with pancreatic cancer,” he noted. “If successful in pancreatic cancer, this approach could pave the way for developing therapeutic vaccines for various other cancer types.”

Despite advancements in cancer treatment, pancreatic cancer remains one of the most lethal forms of cancer, with only a 13% survival rate at the five-year mark post-diagnosis, as noted by MSK and the American Cancer Society. Novel therapies like the experimental vaccine showcased in the clinical trial are imperative, as conventional treatments such as chemotherapy, radiation, and immunotherapy have shown limited efficacy in tackling pancreatic cancer.
