TransCode Therapeutics announced the initiation of its Phase 2a clinical trial. The study is to evaluate TransCode's lead therapeutic candidate, TTX-MC138, in patients with circulating tumor DNA positive colorectal cancer following curative-intent therapy. The trial is being conducted in collaboration with Quantum Leap Healthcare Collaborative, sponsor of the PRE-I-SPY clinical trial platform. The trial builds on growing clinical and scientific momentum supporting ctDNA-guided strategies targeting minimal residual disease in colorectal cancer. The Phase 2a clinical trial is expected to enroll up to 45 patients with colorectal cancer who have completed standard curative-intent therapy and have no radiographic evidence of disease, but remain or become ctDNA-positive, indicating the presence of minimal residual disease.

About RNAZ
TransCode Therapeutics, Inc. is a clinical-stage oncology company focused on treating metastatic disease. It is defeating cancer through the intelligent design and effective delivery of RNA therapeutics based on its proprietary TTX nanoparticle platform. Its lead candidate, TTX-MC138, targets metastatic tumors overexpressing microRNA-10b, a biomarker of metastasis. The Company is also developing a portfolio of RNA therapeutic candidates to overcome delivery challenges and unlock access to novel genetic targets. Its preclinical programs include TTX-siPDL1 (siRNA modulator of PD-L1), TTX-RIGA (RNA agonist of RIG-I for innate immunity activation), and TTX-siMYC (siRNA inhibitor of c-MYC). Additionally, R&D efforts are exploring the combination of TTX-MC138 and seviprotimut-L technologies to enhance therapeutic impact.
