Taming Disease with Designer Therapeutics
Harnessing synthetic biology to reprogram immunity and fight disease at its core.

Where Biology Meets Breakthroughs
We’re pioneering a new era in immunology. Our mission is to transform the treatment of auto-immune disease and cancer using programmable therapeutics that reshape the immune microenvironment, unlocking disease-fighting responses.
-
Designed to Find and Fight Disease
Programmable therapeutics are engineered to seek out diseased tissue and deliver immune-activating compounds directly to the source.
-
Built for Safety from the Start
Our therapeutics have been rigorously tested in a wide range of sensitive models—including immunocompromised animals and pregnant livestock—with no signs of harmful effects.
-
Boosts the Power of Immunotherapy
Our solutions work hand-in-hand with today’s leading treatments.
TRANSFORMING HEALTHCARE, TOGETHER
From precision diagnostics to next-generation therapeutics, Tranquility Biodesign partners with clinicians, researchers, and innovators to bring powerful, programmable solutions to the front lines of disease treatment.
Rewriting the Rules of Cancer Immunotherapy
At Tranquility Biodesign, we are pioneering a new class of microbial medicines designed to reshape how the immune system interacts with cancer. Our lead platform is an engineered bacterial therapeutic that directly targets solid tumors, remodels the tumor microenvironment, and boosts the power of immune-based treatments — all with a focus on safety, precision, and performance.
