About Nanvuranlat
Nanvuranlat (development code: JPH203) is a novel LAT1-selective inhibitor originally discovered by J-Pharma and is the first small-molecule compound of its kind to be clinically developed worldwide. LAT1 (L-type amino acid transporter 1) is one of the transporters involved in cellular amino acid uptake and is known to be highly expressed in many cancer cells. If approved, nanvuranlat could become a first-in-class drug with a new mechanism of action for its target disease.

Since 2015, J-Pharma has conducted Phase I clinical studies in multiple solid tumors and identified its potential for the treatment of advanced biliary tract cancer. A Phase II trial in advanced biliary tract cancer, initiated in 2018, demonstrated a significant improvement in progression-free survival (PFS) compared with placebo and a favorable safety profile.*

Nanvuranlat was designated as an orphan drug by the U.S. Food and Drug Administration (FDA) in April 2022. Furthermore, on September 25, 2024, the Investigational New Drug (IND) application for clinical studies in cancer patients was accepted by the FDA. In addition, in May 2025, J-Pharma confirmed that the Chemistry, Manufacturing, and Controls (CMC) at the commercial manufacturing scale meet the quality standards required by the FDA. Based on these developments, the Company initiated a global Phase III clinical trial in December 2025.
