YolTech Therapeutics, a clinical-stage biotech company specializing in in vivo genome editing therapies, has successfully closed an approximately $45 million Series B financing round. The funding, led by the AstraZeneca-CICC healthcare investment fund, will be used to advance YolTech's clinical programs and support its global strategic operations. Founded in 2021, the company focuses on developing one-time, next-generation in vivo gene-editing therapies. Its fully integrated platform includes proprietary CRISPR nucleases (YolCas), base editors (YolBE), and an advanced lipid nanoparticle delivery system (Yol-LNPs), which enables precise, efficient, and tissue-specific gene editing across various therapeutic areas., a clinical-stage biotech company specializing in in vivo genome editing therapies, has successfully closed an approximately $45 million Series B financing round.

YolTech has a robust clinical pipeline, with four programs currently in the clinical stage. In 2024, its lead program, YOLT-201, a CRISPR-based therapy for transthyretin amyloidosis (ATTR), became the first in vivo gene-editing therapy in China to enter a Phase I/IIa clinical trial. The company has since advanced programs addressing familial hypercholesterolemia (HeFH), primary hyperoxaluria type 1 (PH1), and β-thalassemia/sickle cell disease (TDT/SCD). Additionally, the company's base-editing therapy, YOLT-101 for familial hypercholesterolemia (HeFH), holds the distinction of being the first in vivo base-editing program to receive IND clearance in both China and the United States. With one of the most extensive in vivo gene-editing clinical pipelines globally, YolTech operates its own cGMP-compliant manufacturing facility, which supports clinical supply through Phase III and early commercial scale-up, ensuring consistency and scalability for its programs.
