NORTH CHICAGO, Ill., Mar.
4, 2016 – AbbVie (NYSE: ABBV), a global biopharmaceutical company, today
announced the U.S. Food and Drug Administration (FDA) approved IMBRUVICA® (ibrutinib)
as a first-line treatment for patients with chronic lymphocytic leukemia (CLL).1 The
approval is based on data from the randomized, multi-center, open-label Phase 3
RESONATETM-2 (PCYC-1115) trial, which evaluated the use of IMBRUVICA versus
chlorambucil in 269 treatment-naïve patients with CLL or small lymphocytic
lymphoma (SLL) aged 65 years or older. The RESONATE-2 data were previously presented at the American Society of Hematology (ASH)
Annual Meeting in December 2015 and also simultaneously published in The New England Journal of Medicine. IMBRUVICA is jointly
developed and commercialized by Pharmacyclics LLC, an AbbVie company and
Janssen Biotech, Inc.
“This approval represents a significant leap forward for patients
diagnosed with CLL who may want to consider an alternative first-line treatment
to traditional chemotherapy,” said Michael Severino, M.D., executive vice
president, research and development and chief scientific officer, AbbVie.
“AbbVie is committed to making significant improvements in the lives of
patients with hematologic malignancies and will continue to explore ways to
improve treatment options for patients.”
The prevalence of CLL is approximately
115,000 patients in the U.S.2 with approximately 15,000 newly diagnosed patients every year.3 CLL
is a disease of elderly patients, with an average diagnosis age of 71.3
The
National Comprehensive Cancer Network (NCCN) recently published an update to
its clinical practice guidelines for
non-Hodgkin’s lymphomas, granting IMBRUVICA a category 1 recommendation for
certain CLL patients, the highest recommendation assigned by the organization.
Specifically, NCCN recommends IMBRUVICA as a first-line treatment option for
frail CLL patients with significant comorbidities, as well as for CLL patients
with or without del 17p or the genetic mutation TP53 who are 70 years or older,
or younger patients with significant comorbidities. The NCCN guidelines inform
prescribing and reimbursement practices in many institutions in the U.S. and
internationally.

“The progression-free survival data seen in these
previously untreated CLL patients are strong and encouraging,” said Dr. Jan
Burger, M.D., Ph.D., Associate Professor, Department of Leukemia, Division of
Cancer Medicine, The University of Texas MD Anderson Cancer Center, Houston, TX
and the RESONATE-2 lead study investigator.* “This is especially important for
first-line CLL patients, when considering the safety profile. This treatment
represents another option for these patients.”
IMBRUVICA is now approved to treat CLL patients
regardless of their treatment history (treatment-naïve and previously-treated
patients). In addition, IMBRUVICA is approved to treat high-risk CLL patients
with del 17p,1
a genetic aberration that occurs when part of chromosome 17, the
location of the tumor suppressor gene `
IMBRUVICA significantly prolonged
progression-free survival (PFS; primary endpoint) as determined by an
Independent Review Committee (IRC), reducing the risk of progression or death
by 84% versus chlorambucil (hazard ratio [HR], 0.161 [95% confidence interval:
0.091, 0.283]; median PFS: not reached for IMBRUVICA vs. 18.9 months [95%
confidence interval: 14.1, 22.0] for chlorambucil).1 IMBRUVICA
was also associated with a significantly higher IRC-assessed overall response
rate (ORR: a composite of complete and partial responses; 82.4% vs. 35.3%;
P<0 .0001="" chlorambucil.="" span="" versus="">1 Five patients (3.7 percent) in the IMBRUVICA arm
achieved a complete response, compared to two patients (1.5 percent) in the
chlorambucil arm.1
0>
The safety of IMBRUVICA in this patient
population was consistent with previously reported studies. The adverse
reactions (AR) reported in the U.S. Prescribing Information reflect exposure to
IMBRUVICA with a median duration of 17.4 months versus a median exposure to
chlorambucil of 7.1 months: nearly 2.5 times longer exposure for IMBRUVICA.
Warnings and Precautions include hemorrhage, infections, cytopenias, atrial
fibrillation, hypertension, second primary malignancies, embryo-fetal toxicity
and tumor lysis syndrome. The most commonly occurring adverse reactions of all
Grades in CLL patients treated with IMBRUVICA in the RESONATE-2 trial (>20%)
were diarrhea, musculoskeletal pain, cough and rash.

section below.
About the RESONATE-2 Study
RESONATE-2 is a Pharmacyclics-sponsored study
which enrolled 269 treatment-naïve patients with CLL or SLL aged 65 years or
older in the U.S., EU and other regions. Patients were randomized to receive
either IMBRUVICA 420 mg orally, once daily until progression or unacceptable
toxicity, or chlorambucil on days 1 and 15 of each 28-day cycle for up to 12
cycles. The starting dose for chlorambucil in Cycle 1 was 0.5 mg/kg and was
increased based on tolerability in Cycle 2 by increments of 0.1 mg/kg to a
maximum of 0.8 mg/kg. The primary endpoint of the study was PFS as assessed by
an IRC according to the International Workshop on

About IMBRUVICA
IMBRUVICA is a first-in-class, oral, once-daily
therapy that inhibits a protein called Bruton's tyrosine kinase (BTK).1 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.1,4 IMBRUVICA
blocks signals that tell malignant B cells to multiply and spread
uncontrollably.1
IMBRUVICA is approved to treat patients with CLL,
patients with mantle cell lymphoma (MCL) who have received at least one prior
therapy and patients with Waldenström’s macroglobulinemia. Accelerated approval
was granted for the MCL indication based on overall response rate. Continued
approval for this indication may be contingent upon verification of clinical
benefit in confirmatory trials.1
IMBRUVICA was one of the first medicines to
receive U.S. FDA approval via the new Breakthrough Therapy Designation pathway.
IMBRUVICA is being studied alone and in
combination with other treatments in several blood and solid tumor cancers.
More than 6,000 patients have been treated with IMBRUVICA in clinical trials.
Currently, 14 Phase 3 trials have been initiated with IMBRUVICA and more than
90 trials are registered on www.clinicaltrials.gov.
IMPORTANT SAFETY INFORMATION WARNINGS AND
PRECAUTIONS

Chicago, IL 60064
Hemorrhage - Fatal bleeding events have
occurred in patients treated with IMBRUVICAÒ. Grade 3 or higher bleeding events (intracranial
hemorrhage [including subdural hematoma], gastrointestinal bleeding, hematuria,
and post-procedural hemorrhage) have occurred in up to 6% of patients. Bleeding
events of any grade, including bruising and petechiae, occurred in
approximately half of patients treated with IMBRUVICAÒ.
The mechanism for the bleeding events is not well
understood. IMBRUVICAÒ
may increase the risk of hemorrhage in patients receiving antiplatelet
or anticoagulant therapies and patients should be monitored for signs of
bleeding. Consider the benefit-risk of withholding IMBRUVICAÒ for
at least 3 to 7 days pre- and postsurgery depending upon the type of surgery
and the risk of bleeding.
Infections - Fatal and nonfatal
infections have occurred with IMBRUVICAÒ therapy. Grade 3 or greater infections occurred
in 14% to 26% of patients. Cases of progressive multifocal leukoencephalopathy
(PML) have occurred in patients treated with IMBRUVICAÒ.
Evaluate patients for fever and infections and treat appropriately.
Cytopenias - Treatment-emergent Grade 3
or 4 cytopenias including neutropenia (range, 19% to 29%), thrombocytopenia
(range, 5% to 17%), and anemia (range, 0% to 9%) occurred in patients treated
with IMBRUVICAÒ.
Monitor complete blood counts monthly.
Atrial Fibrillation - Atrial fibrillation
and atrial flutter (range, 6% to 9%) have occurred in patients treated with IMBRUVICAÒ,
particularly in patients with cardiac risk factors, hypertension, acute
infections, and a previous history of atrial fibrillation. Periodically monitor
patients clinically for atrial fibrillation. Patients who develop arrhythmic
symptoms (eg, palpitations, lightheadedness) or new-onset dyspnea should have
an ECG performed. Atrial fibrillation should be managed appropriately and if it
persists, consider the risks and benefits of IMBRUVICAÒ treatment
and dose modification.
Hypertension - Hypertension (range, 6% to
17%) has occurred in patients treated with IMBRUVICA® with a median time to
onset of 4.5 months (range, 0.03 to 18.40 months). Monitor patients for
new-onset hypertension or hypertension that is not adequately controlled after
starting IMBRUVICA®. Adjust existing antihypertensive medications and/or
initiate antihypertensive treatment as appropriate.
Second Primary Malignancies -
Other malignancies (range, 5% to 16%) including non-skin carcinomas (range, 1%
to 4%) have occurred in patients treated with IMBRUVICAÒ. The
most frequent second primary malignancy was non-melanoma skin cancer (range, 4%
to 13%).

Chicago, IL 60064
Tumor Lysis Syndrome - Tumor lysis syndrome
has been infrequently reported with IMBRUVICAÒ therapy. Assess the baseline
risk (eg, high tumor burden) and take appropriate precautions. Monitor patients
closely and treat as appropriate.
Embryo-Fetal Toxicity -
Based on findings in animals, IMBRUVICAÒ can cause fetal harm when administered to a
pregnant woman. Advise women to avoid becoming pregnant while taking IMBRUVICAÒ and
for 1 month after cessation of therapy. If this drug is used during pregnancy
or if the patient becomes pregnant while taking this drug, the patient should
be apprised of the potential hazard to a fetus.
ADVERSE REACTIONS
The most common adverse reactions (≥20%) in
patients with B-cell malignancies (MCL, CLL, WM) were thrombocytopenia* (57%,
53%, 43%), diarrhea (51%, 48%, 37%), anemia* (41%, 37%, 13%), neutropenia*
(47%, 46%, 44%), musculoskeletal pain (37%, 32%†, NA‡), fatigue (41%, 29%,
21%), bruising (30%, 25%†, 16%†), nausea (31%, 24%, 21%), rash (25%, 23%†,
22%†), and upper respiratory tract infection (34%, 19%, 19%).
*Based on adverse reactions and/or laboratory measurements (noted as
platelets, neutrophils, or hemoglobin decreased). †Includes multiple ADR terms.
‡Not
applicable; no associated ADRs.
The most common Grade 3 or 4 non-hematologic
adverse reactions (≥5%) in MCL patients were pneumonia (7%), abdominal pain
(5%), atrial fibrillation (5%), diarrhea (5%), fatigue (5%), and skin
infections (5%). Approximately 4% (CLL), 14% (MCL), and 11% (WM) of patients
had a dose reduction due to adverse reactions.
Approximately 4%-10% (CLL), 9% (MCL), and 6% (WM)
of patients discontinued due to adverse reactions. Most frequent adverse
reactions leading to discontinuation were pneumonia, subdural hematomas, and
atrial fibrillation (1% each) in CLL patients and subdural hematoma (1.8%) in
MCL patients.
