LOXO-305 is an investigational, novel, selective non-covalent Bruton’s tyrosine kinase (BTK) inhibitor. LOXO-305 was designed to reversibly bind BTK, preserve activity in the presence of the acquired resistance, and avoid off-target kinases that have complicated the development of both covalent and investigational non-covalent BTK inhibitors.LOXO-305 is a highly selective, non-covalent BTKi that inhibits both wild type (WT) and C481-mutated BTK with equal low nM potency was developed.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
