Company Overview:

Strand Therapeutics is a clinical stage biotechnology company utilizing synthetic biology to genetically program mRNA to deliver truly revolutionary immunotherapies to patients.

Building on the idea of creating smart therapies based on Boolean logic circuits, Strand was started by biological engineers working together at MIT who were seeking to apply the concept of the emerging field of mRNA therapeutics. Strand's technology is therapeutic-area and mRNA modality agnostic where therapeutic proteins are encoded onto modified, self-replicating, or circular mRNA backbones which in turn are programmed with cell-specific sensors and circuits.

Today, Strand has established three platforms with one clinical stage asset and several programs in preclinical development as well as early discovery. Our lead program, STX-001, is currently being evaluated in a phase 1 clinical trial for solid tumors. Our corporate headquarters is located in the Fenway district of Boston, Massachusetts.
