As part of the PRE-I-SPY platform, the TTX-MC138 Phase 2a dose-expansion portion of the trial will enroll up to 45 patients with colorectal cancer who have completed standard curative-intent therapy and have positive markers for circulating tumor DNA (ctDNA). Recent studies have demonstrated that ctDNA is a prognostic marker of cancer recurrence and may be indicative of the presence of minimal residual disease (MRD) that could be amenable to early interventions. The Phase 2a trial is planned to begin in the first half of 2026 and will be led by Principal Investigator Dr. Paula Pohlmann of MD Anderson Cancer Center. This clinical trial aims to evaluate the biological and clinical activity of TTX-MC138 in the MRD setting, where we believe the therapeutic intervention may have the greatest opportunity to improve long-term outcomes.

"This IND submission marks a pivotal step in TransCode’s clinical development program, positioning TTX-MC138 where its mechanism of action has the potential to deliver meaningful benefit to patients," said Sue Duggan, TransCode’s Senior VP, Operations. "We are pleased to partner with Quantum Leap’s PRE-I-SPY program to evaluate TTX-MC138 and to support the expansion of this platform into new indications such as colorectal cancer," added Duggan.

The clinical trial will be performed at several clinical sites of the PRE-I-SPY Platform Network, many of which are members of the National Cancer Center Network. Additionally, the program is focused on partnering with the Colorectal Cancer Alliance, a leading advocacy organization. Information on the PRE-I-SPY program and the Phase 2a trial can be found at clinicaltrials.gov (NCT05868226).
