Callietha Investments

Callietha Investments is a private investment firm and family office vehicle that specializes in the life sciences and biotechnology sectors. The company is primarily recognized as a significant institutional investor in the UK biotech landscape, holding major long-term stakes in clinical-stage companies such as Synairgen and Scancell Holdings. Callietha focuses on providing capital to support the development of innovative therapeutic platforms, particularly in the areas of respiratory medicine and oncology. It operates as a strategic financial partner rather than a direct drug developer, and it does not maintain an internal research and development pipeline.
