About Us
ImmuneSensor Therapeutics is a clinical-stage biotechnology company led by a team of experienced biotech executives who are committed to creating novel therapies that harness the body’s innate immune system to treat a wide range of diseases. Leveraging the extensive versatility and therapeutic potential of the cGAS-STING pathway, we are focused on discovering and developing novel medicines that address inflammatory and autoimmune diseases. We are advancing a growing pipeline of cGAS inhibitors, which work to suppress inflammation and autoimmunity.
Our History
Pioneers of cGAS/cGAMP
ImmuneSensor was founded in 2014 based on the seminal research conducted in the laboratory of Dr. Zhijian “James” Chen's at the University of Texas Southwestern Medical Center. In 2012, his groundbreaking discovery of the cyclic GMP-AMP synthase (cGAS) enzyme and its secondary messenger, cyclic GMP-AMP (cGAMP), quickly spawned the scientific community's interest and subsequent research into the role of the cGAS-STING pathway in innate immunity through recognizing dsDNA in the cytosol. The importance of the pathway in activating the immune system and its broad applicability in many diseases is now widely recognized and has catalyzed intense drug development in Biopharma. James Chen, Ph.D., was awarded the 2024 Albert Lasker Basic Medical Research Award for the discovery of the cGAS enzyme.
ImmuneSensor has built on in-licensed intellectual property from UTSW, and is focused on developing a promising pipeline of novel orally available small molecule cGAS inhibitors with first- and best-in-class potential to address inflammatory and autoimmune diseases.
