GenEditBio Doses First Patient in World's First In Vivo CRISPR Trial for TGFBI Corneal Dystrophy
核心洞察
GenEditBio (搜索) has dosed the first patient in a groundbreaking investigator-initiated trial of GEB-101 (搜索), marking the world's first clinical study of an in vivo CRISPR-Cas ribonucleoprotein-based genome editing therapy for TGFBI corneal dystrophy (搜索).
The open-label, dose-escalation study is investigating GEB-101 (搜索)'s tolerability when combined with standard phototherapeutic keratectomy in adults with corneal dystrophy, with the first patient discharged without observable adverse events.
GEB-101 (搜索) represents a potential once-and-done treatment using CRISPR-Cas technology delivered via GenEditBio (搜索)'s proprietary protein delivery vehicle, targeting mutations in the TGFBI gene (搜索) that cause abnormal protein buildup in the corneal stroma.
GenEditBio (搜索) Limited has achieved a significant milestone in genome editing therapeutics by dosing the first patient in an investigator-initiated trial of GEB-101 (搜索), the world's first in vivo CRISPR-Cas ribonucleoprotein-based genome editing investigational therapy for TGFBI corneal dystrophy (搜索). The clinical-stage biotechnology company announced this breakthrough development in collaboration with Prof Xingtao Zhou and his team at the Eye & ENT Hospital of Fudan University in Shanghai, China.
The first patient received GEB-101 (搜索) in May 2025 and was subsequently discharged from the collaborating hospital with no observable adverse events, marking a promising start for this pioneering therapeutic approach.
Novel CRISPR-Based Approach for Rare Eye Disease
TGFBI corneal dystrophy (搜索) represents a group of genetic eye disorders caused by mutations in the TGFBI gene (搜索), resulting in abnormal protein buildup in the stromal layer of the cornea. Patients experience debilitating symptoms including photophobia (搜索), gradual vision loss (搜索), and recurrent corneal erosions (搜索). Current treatment options are limited to phototherapeutic keratectomy and corneal transplantation, both of which carry significant limitations including recurrence and risks of sight-threatening complications.
GEB-101 (搜索) is designed as a once-and-done treatment that uses CRISPR-Cas genome editing technology to target specific loci in the mutated TGFBI gene (搜索). The therapy is encapsulated in ribonucleoprotein form within GenEditBio (搜索)'s proprietary engineered protein delivery vehicle (PDV), administered through intrastromal injection directly into the cornea.
Strong Preclinical Safety Profile
Preclinical assessment in non-human primates demonstrated that GEB-101 (搜索) was well-tolerated after local intrastromal injection and exhibited a high safety profile with virtually undetectable off-target effects. This preclinical research recently received the Excellence in Research Award at the 28th Annual Meeting of the American Society of Gene and Cell Therapy in May 2025.
The ongoing investigator-initiated trial is structured as an open-label, dose-escalation clinical study investigating GEB-101 (搜索)'s tolerability when combined with standard treatment phototherapeutic keratectomy in adults with corneal dystrophy.
Leadership Perspectives on Breakthrough Achievement
"Today, on National Sight Day, we are proud and honored to announce that we have initiated the world's first clinical study of an in vivo genome editing investigational therapy for corneal dystrophy," said Zongli Zheng, PhD, Chairman and Co-Founder of GenEditBio (搜索). "We stand at the frontier of a new era and recognize the transformative potential of this moment is not just for the Company but for the entire field of genetic medicine because the technology has the potential to extend far beyond corneal dystrophy."
Tian Zhu, PhD, CEO and Co-Founder of GenEditBio (搜索), emphasized the rapid translation from laboratory to clinic: "Remarkably, in just one year since initiating our proof-of-concept and preclinical studies, we have successfully integrated our genome editing and delivery technologies to advance this pipeline program from the laboratory to clinical stage, showcasing our competence and dedication to rapidly translate basic research into clinical program to ultimately benefit patients."
