Supporting Your ADCs With Proven Payload And Linker Manufacturing

Highly Potent Active Pharmaceutical Ingredients (HPAPIs) — critical components in oncology, virology, and other targeted therapies — demand specialized infrastructure, rigorous safety controls, and deep technical expertise to ensure secure handling and regulatory compliance. Their extreme potency requires advanced containment systems, carefully designed processes, and highly trained teams capable of managing occupational exposure limits while maintaining product quality and reproducibility.

Building on decades of experience in HPAPI development and manufacturing, SK pharmteco has successfully supported programs ranging from early clinical supply to full-scale commercial production. Our capabilities span the synthesis of complex HPAPIs and key intermediates, supported by robust process optimization, impurity control strategies, and scalable purification technologies.

Leveraging this foundation, we provide custom development and cGMP manufacturing services for antibody–drug conjugate (ADC) payloads and linkers. From gram-scale quantities for early-phase studies to multi-kilogram commercial supply, our facilities and technical teams are equipped to deliver safe, efficient, and compliant solutions tailored to the unique requirements of each ADC program.
