FOR IMMEDIATE RELEASE
Independent Data Monitoring Committee Unanimously Recommends Unblinding of IMBRUVICA® (ibrutinib) Phase III Combination HELIOS Trial Based on Interim Analysis Showing Significant Improvement in Progression-Free Survival in Patients with Chronic Lymphocytic Leukemia or Small Lymphocytic Lymphoma
SUNNYVALE, CA, March 16, 2015 – Pharmacyclics, Inc. (NASDAQ: PCYC) announced today that an Independent Data Monitoring Committee reviewed and assessed HELIOS (CLL3001), an international, Phase III, randomized, double-blind, placebo-controlled trial evaluating IMBRUVICA® (ibrutinib) in combination with bendamustine and rituximab (BR) versus placebo in combination with BR in patients with chronic lymphocytic leukemia or small lymphocytic lymphoma (CLL or SLL, respectively), and unanimously recommended that the study be unblinded based on clinically meaningful and statistically significant treatment benefit in the IMBRUVICA arm. The study has met its primary endpoint, demonstrating a statistically significant improvement in progression-free survival (PFS). The safety profile of IMBRUVICA in combination with BR was consistent with prior clinical experience. IMBRUVICA is jointly developed and commercialized by Pharmacyclics and Janssen Biotech, Inc.
“We are delighted by the superior efficacy observed in CLL and SLL patients treated with IMBRUVICA in combination with BR compared to patients in the placebo-controlled BR arm and look forward to sharing these results with the scientific community and U.S. regulators,” said Danelle James, M.D., M.S., Head of Oncology at Pharmacyclics. “These results build upon early results in the Phase I/II program and are very encouraging as we continue to explore the benefits IMBRUVICA provides to patients when it is combined with other treatments.”
HELIOS, a Janssen-sponsored trial, enrolled 578 CLL or SLL patients who had received at least one line of prior systemic therapy. Patients were randomized to receive either IMBRUVICA orally, once daily in combination with six cycles of BR or placebo orally, once daily with six cycles of BR, with the IMBRUVICA or placebo treatment continuing until disease progression or unacceptable toxicity.
These top-line results will be submitted for presentation at the upcoming American Society of Clinical Oncology (ASCO) Annual Meeting and the full results will be submitted for publication in a peer-reviewed journal. A full study report is being prepared and will be submitted to health authorities for future labeling considerations. More information about the study can be found on www.clinicaltrials.gov.
About IMBRUVICA
IMBRUVICA (ibrutinib) 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.1,2 IMBRUVICA blocks signals that tell malignant B cells to multiply and spread uncontrollably.1
IMBRUVICA is approved for the treatment of patients with chronic lymphocytic leukemia (CLL) who have received at least one prior therapy, CLL patients with del 17p, a genetic mutation that occurs when part of chromosome 17 has been lost, and patients with Waldenström’s macroglobulinemia.1
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). Continued approval for the MCL indication may be contingent upon verification of clinical benefit in confirmatory trials.1
IMBRUVICA is being studied alone and in combination with other treatments in several blood cancers. Over 5,100 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 58 trials are registered on www.clinicaltrials.gov.
IMBRUVICA was one of 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.

IMPORTANT SAFETY INFORMATION
WARNINGS AND PRECAUTIONS
Hemorrhage - Fatal bleeding events have occurred in patients treated with IMBRUVICA®. Grade 3 or higher bleeding events (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 IMBRUVICA®.
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 IMBRUVICA® 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. Grade 3 or greater infections occurred in 14% to 26% of patients. Cases of progressive multifocal leukoencephalopathy (PML) have occurred in patients treated with IMBRUVICA®. Monitor patients for fever and infections and evaluate promptly.
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 IMBRUVICA®. Monitor complete blood counts monthly.
Atrial Fibrillation - Atrial fibrillation and atrial flutter (range, 6 to 9%) have occurred in patients treated with IMBRUVICA®, particularly in patients with cardiac risk factors, 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. If atrial fibrillation persists, consider the risks and benefits of IMBRUVICA® treatment and dose modification.
Second Primary Malignancies - Other malignancies (range, 5 to 14%) including non-skin carcinomas (range, 1 to 3%) have occurred in patients treated with IMBRUVICA®. The most frequent second primary malignancy was non-melanoma skin cancer (range, 4 to 11%).
Tumor Lysis Syndrome - Tumor lysis syndrome has been reported with IMBRUVICA® therapy. Monitor patients closely and take appropriate precautions in patients at risk for tumor lysis syndrome (e.g. high tumor burden).
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.
ADVERSE REACTIONS
The most common adverse reactions (≥25%) in patients with B-cell malignancies (MCL, CLL, WM) were thrombocytopenia, neutropenia, diarrhea, anemia, fatigue, musculoskeletal pain, bruising, nausea, upper respiratory tract infection, and rash. Seven percent of patients receiving IMBRUVICA® discontinued treatment due to adverse events.
DRUG INTERACTIONS
CYP3A Inhibitors - Avoid co-administration with strong and moderate CYP3A inhibitors. If a moderate CYP3A inhibitor must be used, reduce the IMBRUVICA® dose.
CYP3A Inducers - Avoid co-administration with strong CYP3A inducers.
SPECIFIC POPULATIONS
Hepatic Impairment - Avoid use in patients with moderate or severe baseline hepatic impairment. In patients with mild impairment, reduce IMBRUVICA® dose.
