Imbruvica Approved for Leukemia and Lymphoma
FDA has approved an AbbVie supplemental NDA for Imbruvica (ibrutinib) in combination with rituximab for the first-line treatment of patients with chronic lymphocytic leukemia or small lymphocytic lymphoma. The submission was based on data from the Phase 3 E1912 study, which was sponsored by the National Cancer Institute. The study showed “significantly improved progression-free survival (PFS) and overall survival (OS) in patients treated with Imbruvica plus rituximab, compared to those treated with fludarabine, cyclophosphamide and rituximab,” the company says. Safety data were consistent with the currently known safety profile of Imbruvica.
Imbruvica is a once-daily, first-in-class Bruton’s tyrosine kinase (BTK) inhibitor that is administered orally, and is jointly developed and commercialized with Janssen Biotech. It works differently than chemotherapy as it blocks the BTK protein, which AbbVie says sends important signals that tell B cells to mature and produce antibodies. BTK signaling is needed by specific cancer cells to multiply and spread.
Imbruvica was first approved in 2013 and it has received 10 FDA approvals across six disease areas.
