COLONYVAQ™, a Quantum-Classical Guided Personalized Neoantigen Vaccine for MSS Stage III Colorectal Cancer

This is an early phase I, single-arm, open-label clinical study designed to evaluate the safety, tolerability, and feasibility of COLONYVAQ-CRC, a physics-aware, quantum-classical AI-guided personalized neoantigen peptide vaccine, administered in combination with standard adjuvant oxaliplatin-based chemotherapy (mFOLFOX6 or CAPOX) and nivolumab 3 mg/kg in patients with completely resected stage III microsatellite-stable (MSS) / proficient mismatch repair (pMMR) colorectal cancer. An initial safety cohort of 12 patients will be enrolled and closely monitored for toxicity attributable to the experimental vaccine preparation. If, among these 12 patients, fewer than 3 develop experimental-preparation-related toxicity greater than grade 2 and no patient develops experimental-preparation-related grade 4 toxicity, the study will expand to enroll a total of 50 patients. Primary objectives focus on safety and tolerability of the combination regimen. Secondary and exploratory objectives characterize neoantigen-specific immune responses, ctDNA dynamics, T-cell receptor (TCR) clonotype evolution, tumor immune microenvironment features, and preliminary disease control (disease-free survival and overall survival) to inform subsequent phase II design.
