Currently, Spectrum and its affiliates have two oncology drugs in late stage and active development: ROLONTIS, a novel long-acting granulocyte colony-stimulating factor, analog for chemotherapy-induced neutropenia, and Poziotinib, a novel pan-HER inhibitor under investigation for non-small cell lung cancer tumors with either EGFR or HER2 exon-20 insertion mutations.
Spectrum Cayman is owned 99% by Spectrum and 1% by Spectrum Pharmaceuticals International Holdings, LLC, a Delaware limited liability company
(“Spectrum Holdings”). Spectrum Holdings is the sole general partner of Spectrum Cayman and Spectrum is the sole managing member of Spectrum Holdings.
