About YolTech Therapeutics
Founded in 2021, YolTech Therapeutics is advancing next-generation in vivo gene-editing therapies designed for one-time treatment. The company has built a fully integrated platform encompassing proprietary CRISPR nucleases (YolCas), base editors (YolBE), and a cutting-edge lipid nanoparticle delivery system (Yol-LNPs), enabling precise, efficient, and tissue-specific gene editing across a broad range of therapeutic areas.

In 2024, YolTech's lead program YOLT-201, a CRISPR-based therapy for transthyretin amyloidosis (ATTR), became the first in vivo gene-editing therapy in China to enter Phase I/IIa clinical trial. Since then, the company has advanced four clinical-stage programs addressing ATTR, familial hypercholesterolemia (HeFH), primary hyperoxaluria type 1 (PH1), and β-thalassemia/sickle cell disease (TDT/SCD).

YolTech operates a cGMP-compliant manufacturing facility supporting clinical supply through Phase III and early commercial scale-up, ensuring manufacturing consistency and scalability across programs.

With one of the most extensive in vivo gene-editing clinical pipeline globally, YolTech continues to lead in the field. Its base-editing therapy YOLT-101, developed for familial hypercholesterolemia (HeFH), became the first in vivo base-editing program to receive IND clearance in both China and the United States.
