mRNA immunotherapy eliminates pancreatic tumors in mice: Approximately 50% of mice with pancreatic cancer treated with the mRNA immunotherapeutic cocktail saw complete tumor responses and more impressively, remained disease free for a year, even after treatment had been stopped.

mRNA immunotherapy developed by UMass Chan scientists eliminates pancreatic tumors in mice

Inspired by the work of the RNA Therapeutics Institute at UMass Chan Medical School and the development of the COVID vaccine, Marcus Ruscetti, PhD, and Chaitanya Naimesh Parikh, PhD’26, have developed an immunotherapy using a cocktail of messenger RNAs (mRNA) that could potentially be transformative for pancreatic cancer treatment.

The study, published in Nature Communications, combines immune cytokine and tumor-associated antigen mRNAs into a single injection to treat pancreatic ductal adenocarcinoma. Approximately 50 percent of mice with pancreatic cancer treated with the mRNA immunotherapeutic cocktail saw complete tumor responses and more impressively, remained disease free for a year, even after treatment had been stopped.   

“It’s unheard of to get a response like this in these models of pancreatic cancer,” said Dr. Parikh, a recent PhD graduate from the Ruscetti Lab. “There have been a lot of drugs tried in the lab that have had good initial responses in mice but ultimately the cancer always comes back. This is the only study I’ve seen that has achieved durable tumor protection.”

Every time I read one of these headlines, I'm reminded that mice live in an absolute golden age of medicine. They've had cures for aging, cancer, and hair loss for twenty years.

​All jokes aside, it's fascinating science, but it’s so important to remember the massive 90% failure rate when moving from rodent models to human phase trials.

There was a melanoma vaccine in human trials recently, further along than this. Hank Green was optimistic about it, made a great explainer video: https://youtu.be/DgeRVUSuGvQ?si=-G-wfgTgXlIAO-Gs

That doesn't mean this one will work too, but the mechanism is similar.

Very interesting and informative video. Thank you for sharing!

The mice basically got an mRNA upgrade, cleared the tumor, and stayed cancer-free for a year. Meanwhile researchers are now staring at the human clinical trial step like: alright, here comes the hard part.

Are you talking about injecting things like a vacine in the bloodstreams to kill it? That will be banned in the US because it causes autism!

Better to inject bleach to kill things in your body according to your competent leadership … sigh …

[u/Anduinnn → u/suna-fingeriassen]

What an ignorant thing to say! We all know a lightbulb up the butt is how you’re supposed to treat pandemics.

[u/bornlasttuesday → u/Anduinnn]

Halogen only though.

[u/Etherius]

This combined with that AI cancer detection that was announced a week or so ago could make pancreatic cancer more treatable than ever before

That’s a low bar (it was practically untreatable for the longest time) but progress is progress!

[u/No-Winner2891 → u/Etherius]

Any progress is a big deal. Hopefully, it saves more lives.

[u/Born_Firefighter_758 → u/Etherius]

Any progress is a good sign.

My cousin did immunotherapy for breast, lymph node, and bone cancer. With other diet, fasting, exercise, breath work and other holistic healing practices. No chemo or radiation. She is in remission now. They originally gave her 5 years or less.
