## Abstract

Metastatic Ewing Sarcoma remains a critical therapeutic challenge with 5-year survival below 30%. The EWSR1–FLI1 fusion oncogene is undruggable by conventional approaches, requiring integrated bioengineering solutions.

We present CRISPR-TTP, a modular architecture combining high-fidelity CRISPR-Cas9 genome engineering (>94% efficiency), FUS-programmable temporally controlled delivery via HOF-nanoparticles (1–2 mm spatial resolution), dendritic cell autovaccination, and PD-1 blockade. A multimodal AI system orchestrates real-time personalization and optimization.

In silico modeling predicts ∼96.3% tumor growth inhibition and a ∼65% improvement in median survival. CD8+ T-cell infiltration increases ∼3.2-fold. AI-optimized sgRNA prediction accuracy reaches 89.3%.

This CC0-licensed architecture defines a new standard for integrated, spatiotemporally programmable precision oncology and is suitable for compassionate-use-ready translational deployment.
