Filing completed less than two months after first European approval for IMBRUVICA®
SUNNYVALE, Calif., Dec. 1, 2014 /PRNewswire/ -- Pharmacyclics, Inc. (NASDAQ: PCYC) today announced the acceptance of a Type II variation application for IMBRUVICA® (ibrutinib) by the European Medicines Agency (EMA). This submission, filed by strategic partner Janssen-Cilag International NV (Janssen), represents a potential label expansion for IMBRUVICA in the European Union (EU) for the treatment of adult patients with Waldenstrom's macroglobulinemia (WM), a rare type of B-cell lymphoma for which treatment options are limited in the EU. If approved, IMBRUVICA would be the first label specifically authorized to treat WM.
IMBRUVICA is a first-in-class, oral, once-daily, therapy being jointly developed and commercialized in the United States (U.S.) by Pharmacyclics and Janssen Biotech, Inc. Janssen affiliates will hold the marketing authorization and market IMBRUVICA in EMEA (Europe, Middle East, Africa), as well as the rest of the world, outside the U.S.
"This additional application in the EU shows the priority and urgency with which we, and our collaboration partner Janssen, pursue the ongoing potential for IMBRUVICA," said Thorsten Graef, M.D., Ph.D., Vice President of Clinical Science, Pharmacyclics. "If approved, IMBRUVICA could address a very important unmet need for patients with WM in Europe, who currently have limited treatment options."
The acceptance of the WM Type II variation submission for IMBRUVICA triggers a $20 million milestone payment to Pharmacyclics under its collaboration agreement with Janssen Biotech, Inc.
The EMA WM filing follows the supplemental New Drug Application submission for IMBRUVICA to the U.S. Food and Drug Administration (FDA), which was submitted by Pharmacyclics in October 2014, for its use in the treatment of patients with WM. Both the FDA and EMA filings were based on data from a Phase II study evaluating the use of IMBRUVICA in WM patients, which was led by Dr. Steven Treon from the Dana-Farber Cancer Institute.
WM is a slow-growing, currently incurable, rare type of B-cell lymphoma for which there are no EU-wide approved drugs. The median age at diagnosis is 63-68 years of age and incidence rates among men and women in the EU are approximately 7.3 and 4.2 per million persons, respectively. WM begins with a malignant change to the B cell, a type of white blood cell (lymphocyte), during its maturation so that it continues to reproduce more malignant B cells.
IMBRUVICA® (ibrutinib) is a first-in-class, oral, once-daily therapy that inhibits a protein called Bruton's tyrosine kinase (BTK). BTK is a key signaling molecule in the B-cell receptor signaling complex that plays an important role in the survival and spread of malignant B cells. IMBRUVICA blocks signals that tell malignant B cells to multiply and spread uncontrollably.
IMBRUVICA is approved for the treatment of patients with chronic lymphocytic leukemia (CLL) who have received at least one prior therapy, and for the treatment of CLL patients with del 17p, a genetic mutation that occurs when part of chromosome 17 has been lost.
IMBRUVICA is also approved for the treatment of patients with mantle cell lymphoma (MCL) who have received at least one prior therapy. Accelerated approval was granted for the MCL indication based on overall response rate (ORR). Improvements in survival or disease-related symptoms have not been established. Continued approval for the MCL indication may be contingent upon verification of clinical benefit in confirmatory trials.
IMBRUVICA is being studied alone and in combination with other treatments in several blood cancers including CLL, MCL, WM, diffuse large B-cell lymphoma (DLBCL), follicular lymphoma (FL) and multiple myeloma (MM). Over 4,600 patients have been treated in clinical trials of IMBRUVICA conducted in 35 countries by more than 800 investigators. Currently, 13 Phase III trials have been initiated with IMBRUVICA and 55 trials are registered on www.clinicaltrials.gov. The overall clinical development program in CLL currently includes seven Phase III trials and covers all lines of therapy and various combinations of treatments.
IMBRUVICA was one the first medicines to receive U.S. FDA approval via the new Breakthrough Therapy Designation pathway, and is the only product to have received three Breakthrough Therapy Designations.
IMBRUVICA is jointly developed and commercialized by Pharmacyclics and Janssen Biotech, Inc.
IMBRUVICA is indicated to treat people with:
- Chronic lymphocytic leukemia (CLL) who have received at least one prior therapy.
- Chronic lymphocytic leukemia (CLL) with 17p deletion (a genetic mutation that occurs when part of chromosome 17 has been lost).
- Mantle cell lymphoma (MCL) who have received at least one prior therapy
- Accelerated approval was granted for this indication based on overall response rate. Improvements in survival or disease-related symptoms have not been established. Continued approval for this indication may be contingent upon verification of clinical benefit in confirmatory trials.
Patients taking IMBRUVICA for CLL should take 420 mg taken orally once daily (or three 140 mg capsules once daily).
Patients taking IMBRUVICA for MCL should take 560 mg taken orally once daily (or four 140 mg capsules once daily).
Capsules should be taken orally with a glass of water. Capsules should be taken whole. Do not open, break, split or chew the capsules.
