Something off on this page? Send us feedback.
Discovers and develops therapeutic proteins and antibodies that modulate GPCR activity, with TX45 in pulmonary hypertension programs and TX2100 in HHT. Operations are centered in Watertown, Massachusetts, and the business remains tied to clinical trial execution rather than marketed product sales.
Builds therapeutic proteins and antibodies that modulate GPCR activity, using the GEODe discovery platform to work through receptor-expression, engineering, selection, protein-engineering, and structural-biology challenges. The platform lineage traces to Harvard Medical School components later modified by the company.
Current development is anchored by TX45, an Fc-relaxin fusion aimed at pulmonary hypertension settings, and TX2100, an APJ-receptor antagonist for hereditary hemorrhagic telangiectasia. Operations are centered in Watertown, Massachusetts, with a small R&D-heavy employee base and no marketed products identified.
Execution depends on clinical readouts, trial enrollment, and financing capacity for the pipeline created after the AVROBIO reverse merger. The public security began trading as TECX in 2024, so the listed-company history is short and shaped by reverse-merger lineage.
