Phase I Dose-Escalation Study of MT027: Evaluating Tolerability, Safety, Pharmacokinetics, and Preliminary Efficacy in Patients With Advanced Peritoneal Malignancies or Abdominal Metastatic Solid Tumors

Study Summary

This is an open-label, single-arm phase I dose-escalation study designed to evaluate the safety, tolerability, pharmacokinetic profile, and preliminary efficacy of MT027 in patients with advanced primary peritoneal malignancies or abdominal metastases secondary to malignant solid tumors. The study primarily focuses on determining the maximum tolerated dose and recommended phase II dose through sequential cohort dose escalation, while secondarily characterizing the pharmacokinetic parameters and collecting initial efficacy data regarding tumor response. This investigation comprehensively evaluates the pharmacodynamic and pharmacokinetic profile of MT027 cellular therapy through three primary objectives: (1) systematic monitoring of treatment-emergent adverse events and clinically significant laboratory parameter deviations; (2) assessment of antitumor activity with correlative biomarker analysis; and (3) characterization of cellular kinetics including biodistribution patterns, mechanistic pathways of therapeutic activity, and comprehensive immunogenicity assessment measuring both cellular/humoral immune responses against MT027 cells. The protocol further investigates potential host-versus-product immune reactions through longitudinal monitoring of donor-specific antibodies and cytokine release profiles, while employing advanced molecular tracking methodologies to elucidate cellular persistence and functional modulation within the tumor microenvironment.
