Lattice-Based Radiotherapy and Chemo-Immunotherapy for Oral Cavity Squamous Cell Carcinoma

Summary

Single-arm, two-part, phase IB safety study that uses a Bayesian Optimal Interval (BOIN-12) dose-escalation scheme. Part 1 (Dose Finding) - Sentinel start at 9 Gy × 3 followed by fixed 3-patient BOIN cohorts exploring 8 Gy × 3 → 9 Gy × 3 → 10 Gy × 3. Target DLT rate θ = 0.20; ≈ 7-15 participants. Part 2 (Expansion) - Additional enrolment at the selected maximum tolerated dose (MTD) until ≈ 30 evaluable subjects (Parts 1 + 2 combined). Patients receive peaks to the primary tumor alone (Group A) or to the primary + involved nodes (Group B) at the investigators' discretion (non-random). Surgery occurs 6-8 weeks after RT; adjuvant therapy is pathology-driven.
