Pharmacyclics Files Supplemental New Drug Application for IMBRUVICA with Phase
                              III CLL Study Data

PR Newswire

SUNNYVALE, Calif., April 8, 2014

SUNNYVALE, Calif., April 8, 2014 /PRNewswire/ --Pharmacyclics, Inc. (NASDAQ:
PCYC) today announced that it has submitted a supplemental New Drug
Application (sNDA) to the U.S. Food and Drug Administration (FDA), based on
data from the randomized, multi-center, open-label Phase III RESONATE^TM
study, PCYC-1112, a head-to-head comparison of single agent IMBRUVICA^TM
(ibrutinib) versus ofatumumab in 391 patients with chronic lymphocytic
leukemia (CLL) or small lymphocytic lymphoma (SLL), who had received at least
one prior therapy. IMBRUVICA is being jointly developed and commercialized by
Pharmacyclics and Janssen Biotech, Inc.

At a planned interim analysis in January 2014, the results of the RESONATE
study demonstrated a statistically significant improvement in progression-free
survival, the primary endpoint of the study, in patients treated with
IMBRUVICA. Further, patients in the IMBRUVICA arm also showed a statistically
significant improvement in overall survival, a key secondary endpoint of the
trial. The safety profile of IMBRUVICA was acceptable and showed a favorable
risk benefit profile. Data from this study will be discussed in a presentation
at the 50^th annual meeting of the American Society of Clinical Oncology in
Chicago, May 30 – June 3, 2014.

"This supplemental new drug application in previously treated CLL patients is
our first Phase III submission to the FDA seeking full approval for the use of
IMBRUVICA. It is another major milestone in our clinical development plan,
which currently includes 10 Phase III studies," said Bob Duggan, CEO and
Chairman of the Board of Pharmacyclics. "Our company's mission is to serve as
an ally to patients. In the RESONATE study, single agent IMBRUVICA provided a
significant benefit for patients with CLL. We look forward to working with the
FDA as they review the data from this Phase III study."

The FDA granted an accelerated approval for IMBRUVICA as a single agent for
the treatment of patients with MCL or CLL, who have received at least one
prior therapy. The accelerated approval for these indications was based on the
overall response rate (ORR) of patients in the Phase II clinical studies of
PCYC-1102 and PCYC-1104. An improvement in survival or disease-related
symptoms was not established in these studies. IMBRUVICA is the first
once-daily, single-agent, oral kinase inhibitor for patients with MCL or CLL
who have received one prior therapy.

CLL is a slow-growing blood cancer of the white blood cells (lymphocytes),
most commonly B-cells. CLL is the most common adult leukemia. Approximately
16,000 patients in the U.S. are diagnosed each year with CLL. The prevalence
of CLL is approximately 114,500 in the U.S. CLL is a chronic disease that
predominantly occurs in the elderly and the average age of diagnosis is 72.The
five-year survival is approximately 82 percent.

MCL is also a blood cancer; it is an aggressive type of B-cell non-Hodgkin
lymphoma (NHL) that usually occurs in older adults. The disease typically
involves the lymph nodes, but can spread to other tissues, such as bone
marrow, liver, spleen, and gastrointestinal tract. The prevalence of MCL is
approximately 11,300 in the U.S. and patients survive an average of five
years.

CLL and MCL are both classified as orphan or rare diseases, defined as agents
which affect fewer than 200,000 Americans. ^ Patients commonly receive
multiple lines of treatment over the course of their disease.

INDICATIONS

IMBRUVICA is indicated for the treatment of:

  oPatients with mantle cell lymphoma (MCL) who have received at least one
    prior therapy.
  oPatients with chronic lymphocytic leukemia (CLL) who have received at
    least one prior therapy.

The FDA's accelerated approval of these indications was based on the overall
response rate of patients in the Phase II clinical trials of PCYC-1102 and
PCYC-1104. Improvements in survival or disease-related symptoms were not
established in these studies.

IMPORTANT SAFETY INFORMATION

WARNINGS AND PRECAUTIONS

Hemorrhage – Five percent of patients with MCL and 6% of patients with CLL had
Grade 3 or higher bleeding events (subdural hematoma, ecchymoses,
gastrointestinal bleeding, and hematuria). Overall, bleeding events including
bruising of any grade occurred in 48% of patients with MCL treated with 560 mg
daily and 63% of patients with CLL treated at 420 mg daily.

The mechanism for the bleeding events is not well understood. IMBRUVICA may
increase the risk of hemorrhage in patients receiving antiplatelet or
anticoagulant therapies. Consider the benefit-risk of withholding IMBRUVIC for
at least 3 to 7 days pre and post-surgery depending upon the type of surgery
and the risk of bleeding.

Infections - Fatal and non-fatal infections have occurred with IMBRUVICA
therapy. At least 25% of patients with MCL and 35% of patients with CLL had
infections Grade 3 or greater NCI Common Terminology Criteria for Adverse
Events (CTCAE). Monitor patients for fever and infections and evaluate
promptly.

Myelosuppression - Treatment-emergent Grade 3 or 4 cytopenias were reported in
41% of patients with MCL and 35% of patients with CLL. These included
neutropenia (29%), thrombocytopenia (17%) and anemia (9%) in patients with MCL
and neutropenia (27%) and thrombocytopenia (10%) in patients with CLL. Monitor
complete blood counts monthly.

Renal Toxicity - Fatal and serious cases of renal failure have occurred with
IMBRUVICA therapy. Treatment-emergent increases in creatinine levels up to 1.5
times the upper limit of normal occurred in 67% of patients with MCL and 23%
of patients with CLL. Increases in creatinine 1.5 to 3 times the upper limit
of normal occurred in 9% of patients with MCL and 4% of patients with CLL.
Periodically monitor creatinine levels. Maintain hydration.

Second Primary Malignancies - Other malignancies have occurred in 5% of
patients with MCL and 10% of patients with CLL who have been treated with
IMBRUVICA. Four percent of patients with MCL, had skin cancers, and 1% had
other carcinomas. Eight percent of patients with CLL had skin cancers and 2%
had other carcinomas.

Embryo-Fetal Toxicity - Based on findings in animals, IMBRUVICA can cause
fetal harm when administered to a pregnant woman. Advise women to avoid
becoming pregnant while taking IMBRUVICA. 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.

About IMBRUVICA
IMBRUVICA is indicated for the treatment of patients with mantle cell lymphoma
or chronic lymphocytic leukemia who have received at least one prior
therapy.^1 For more information about IMBRUVICA, including the full
prescribing information, please visit www.IMBRUVICA.com. IMBRUVICA is a first
in class, oral therapy and is a new agent that inhibits a protein called
Bruton's tyrosine kinase (BTK).^1 BTK is a key signaling molecule of the
B-cell receptor signaling complex that plays an important role in the survival
and spread of malignant B cells.^8,9,10 IMBRUVICA blocks signals that tell
malignant B cells to multiply and spread uncontrollably.^1,11 It is one of the
first medicines to file for FDA approval via the new Breakthrough Therapy
Designation pathway, enabling Pharmacyclics to rapidly bring this medicine to
patients in need.
