ASO Treatment for Syndromic Craniosynostoses

Observational NCT07535372 Kind: OBSERVATIONAL Apr 17, 2026

Abstract

Syndromic craniosynostoses (SCS) are rare genetic disorders defined by premature cranial suture fusion, resulting in abnormal craniofacial development and constrained brain growth. These conditions, including Muenke, Saethre-Chotzen, Crouzon, Apert, Pfeiffer and craniofrontonasal syndromes, are typically caused by gain- or loss-of-function variants in key regulators of suture biology such as FGFR1/2/3, TWIST1 and TCF12. Current management is exclusively surgical, relying on early cranial vault remodelling and subsequent reconstructive procedures, which carry substantial risks (e.g. blood loss, infection, re-synostosis) and do not address the underlying molecular etiology.

Recent advances in RNA-based therapeutics have demonstrated the potential of mutation-specific approaches to normalize aberrant osteogenic differentiation in patient-derived cells. However, clinical translation remains limited by inefficient delivery and lack of sustained therapeutic activity. The NAUTILUS project aims to overcome these barriers by developing a non-invasive, ultra-personalized therapeutic platform based on mutation-specific antisense oligonucleotides (ASOs) delivered via a nano-engineered system.

The project will design and validate patient-tailored ASOs targeting the molecular drivers of SCS, with the goal of either silencing pathogenic gain-of-function alleles or restoring physiological expression in loss-of-function contexts. Functional efficacy will be assessed in patient-derived ce...
