Overview of Tucatinib and Its Manufacturing Landscape

Tucatinib (development code: ONT-380) was developed by Array BioPharma, now under the umbrella of Seagen Inc. (formerly Seattle Genetics), approved for treating HER2-positive metastatic breast cancer alongside other therapies (FDA approval in 2020). The demanding synthesis process, involving complex chemical reactions and strict purity requirements, underscores the importance of sourcing API from reputable manufacturers with proven quality management systems.

Given the molecule’s recent market introduction and specialized synthesis procedures, API sourcing options are comparatively limited but are expanding as manufacturing capacities scale. The key considerations extend beyond mere availability—regulatory compliance, consistent quality, and the ability to meet commercial-scale demands define supplier viability.
