Independent Data Monitoring Committee determines HELIOS study meets its primary endpoint of progression-free survival in patients with previously treated chronic lymphocytic leukemia/small lymphocytic lymphoma at a pre-planned interim analysis
RARITAN, NJ, March 16, 2015 - Janssen Research & Development, LLC (Janssen) announced today that a pre-planned interim analysis of the Phase 3 HELIOS (CLL3001) study investigating the combination of IMBRUVICA® (ibrutinib) plus bendamustine and rituximab (BR) versus placebo plus BR in patients with relapsed or refractory chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL), showed the trial has met its primary endpoint, demonstrating a statistically significant improvement in progression-free survival (PFS). An Independent Data Monitoring Committee (IDMC) recommends that the study be unblinded and patients receiving placebo plus BR should be offered the option to receive IMBRUVICA as their next treatment. IMBRUVICA is jointly developed and commercialized by Janssen Biotech, Inc. and Pharmacyclics, Inc.
"This is the second randomized, controlled study in patients with previously treated CLL or SLL to show a significant improvement in progression-free survival, further underscoring the potential of IMBRUVICA," said Sen Zhuang, M.D., Ph.D., Vice President, Oncology Clinical Research, Janssen. "The data from the Phase 3 RESONATE trial demonstrated that IMBRUVICA as a single agent significantly improved both progression-free and overall survival compared to ofatumumab. Now, the interim data from HELIOS demonstrate that IMBRUVICA may be incorporated into a regimen with bendamustine and rituximab to improve outcomes for patients."
HELIOS is a Janssen-sponsored, randomized, double-blind, placebo-controlled, international, multicenter Phase 3 study conducted in 21 countries, which evaluated the safety and efficacy of IMBRUVICA in combination with BR in 578 patients with relapsed or refractory CLL/SLL who had received at least one prior therapy. Patients were randomized to receive either the combination of 420 mg IMBRUVICA orally once daily and six cycles of BR, or a matching regimen of placebo orally once daily and six cycles of BR, with IMBRUVICA or placebo continued until disease progression or unacceptable toxicity.
The primary endpoint of the HELIOS study is PFS, with secondary endpoints including safety (adverse events), overall response rate (ORR), overall survival (OS), rate of minimal residual disease (MRD)-negative responses and other improvements in hematologic values, disease-related symptoms and patient-reported outcome scores.
These topline results are planned to be submitted for presentation at the upcoming American Society of Clinical Oncology (ASCO) Annual Meeting, as well as for publication in a peer-reviewed journal. A full study report is being prepared and planned to be submitted to health authorities for future labeling considerations. For additional study information, visit ClinicalTrials.gov.
IMBRUVICA was one of the first therapies to receive U.S. approval after having received the FDA's Breakthrough Therapy Designation. IMBRUVICA works by blocking a specific protein called Bruton's tyrosine kinase (BTK).1 The BTK protein transmits important signals that tell B cells to mature and produce antibodies and is needed by specific cancer cells to multiply and spread.1,2 IMBRUVICA targets and blocks BTK, inhibiting cancer cell survival and spread.1 For more information, visit www.IMBRUVICA.com.
Additional Information about IMBRUVICA®
IMBRUVICA is indicated to treat people with:
Mantle cell lymphoma (MCL) who have received at least one prior therapy
Accelerated approval was granted for this indication based on overall response rate. Continued approval for this indication may be contingent upon verification of clinical benefit in confirmatory trials.
Chronic lymphocytic leukemia (CLL) who have received at least one prior therapy
Chronic lymphocytic leukemia (CLL) with 17p deletion
Waldenström's macroglobulinemia (WM)
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.
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.
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.
Hepatic Impairment - Avoid use in patients with moderate or severe baseline hepatic impairment. In patients with mild impairment, reduce IMBRUVICA® dose.

About Chronic Lymphocytic Leukemia
Chronic Lymphocytic Leukemia (CLL) is a slow-growing blood cancer that most commonly arises from B cells, a type of white blood cell (lymphocyte) that originates in the bone marrow.3,4 CLL is predominantly a disease of the elderly, with a median age of 71 at diagnosis.3
