WHO Publishes INN Proposed List 134 with New Drug Names and Structures
The World Health Organization has released INN Proposed List 134 in January 2026, disclosing non-proprietary names and structures for investigational drugs. This follows earlier lists published in July 2025 (List 133) and February 2025 (List 132), providing comprehensive data on drug candidates in development.
The World Health Organization has published its INN Proposed List 134 in January 2026, revealing non-proprietary names, disease indications, and chemical structures for a broad range of investigational drugs currently in clinical trials. The latest list provides insight into the drug development landscape by linking newly disclosed International Nonproprietary Names with active compounds in company pipelines.
The INN Proposed List 133 was released in July 2025, unveiling the latest batch of drug names currently under consideration by the WHO. This list includes company identifiers, newly proposed drug names, structural information, original patents, companies, and mechanisms of action, including structures that were previously undisclosed.
Earlier, the INN Proposed List 132 was released on February 13th, 2025, providing similar comprehensive information about proposed drug names and their corresponding chemical structures. These lists serve as important resources for tracking pharmaceutical development, offering searchable tables that compile small molecule information including therapeutic targets, relevant patents, and preclinical and clinical data underlying applications for non-proprietary names.
The systematic publication of these lists allows researchers and industry professionals to monitor emerging drug candidates across various therapeutic areas. The information includes mechanisms of action and structural details that were previously undisclosed, providing valuable insights into ongoing pharmaceutical research and development efforts worldwide.
