Imbruvica targets and blocks BTK, inhibiting cancerous B cells to survive and spread. Imbruvica is currently being studied alone in combination with other treatments in several blood and solid tumor cancers and other serious illnesses.
Imbruvica is co-developed and commercialized by Pharmacyclics, an AbbVie company, and Janssen Biotech.
