Pharmacyclics CEO Bob Duggan said: "We are very pleased that patients with CLL and relapsed or refractory MCL in the European Union will have a first-in-class, oral, single-agent, non-chemotherapy treatment option in Imbruvica.
"This approval underscores the compelling safety and efficacy benefits of Imbruvica, including statistically significant improvement in overall survival and progression-free survival in CLL and the overall robustness of the data in MCL."
The approval was granted based on data from the Phase II study (PCYC-1104) in MCL, the Phase III Resonate study (PCYC-1112-CA) in CLL and small lymphocytic lymphoma (SLL) and the Phase Ib/II study (PCYC-1102) in CLL/SLL.
Pharmacyclics, along with Janssen Biotech, has developed and commercialised Imbruvica in the US. Janssen affiliates will sell Imbruvica in Europe, Middle East, Africa (EMEA), and rest of the world outside the US, as they hold the marketing authorisation.

Pharmacyclics noted that accelerated approval was granted for the MCL indication based on overall response rate (ORR).
