Additional Efficacy and Safety Data for IMBRUVICA® (Ibrutinib) Submitted to FDA

Data submission includes findings from the Phase 3 HELIOS (CLL3001) trial evaluating ibrutinib plus bendamustine and rituximab in patients with relapsed/refractory chronic lymphocytic leukemia or small lymphocytic lymphoma

HORSHAM, Pa., Nov. 13, 2015 /PRNewswire/ -- Janssen Biotech, Inc. announced a supplemental New Drug Application (sNDA) for IMBRUVICA® (ibrutinib) has been submitted to the U.S. Food and Drug Administration (FDA), based on results from the Phase 3 HELIOS (CLL3001) trial evaluating 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).

IMBRUVICA is jointly developed and commercialized by Janssen and Pharmacyclics LLC, an AbbVie company. Pharmacyclics is the investigational new drug (IND) holder for IMBRUVICA in the U.S. and submitted the application to the FDA on behalf of the companies. Janssen sponsored this study.

"The Phase 3 HELIOS study provides further efficacy and safety evidence around the potential of IMBRUVICA in combination with BR as an effective and tolerable treatment option within the existing previously treated chronic lymphocytic leukemia treatment landscape: suitable both as a monotherapy, for which it's already approved, and also as a complement to standard chemotherapies for relapsed/refractory CLL patients," said Simon Rule, M.D., Consultant Haematologist, Department of Haematology, and Head of the Lymphoma Service, Derriford Hospital, Plymouth, UK, and HELIOS study investigator.  

The interim data were presented and included in the official press program at the American Society of Clinical Oncology (ASCO) Annual Meeting in June 2015 and showed the combination of ibrutinib+BR significantly reduced the risk of progression or death by 80% (HR=0.203, 95% CI: 0.150-0.276, P< 0.0001) and also significantly improved overall response rate (ORR) in previously treated CLL/SLL patients compared to placebo+BR. The Independent Review Committee (IRC)-assessed ORR and complete response/complete response with incomplete marrow recovery (CR/CRi) rates were 82.7% and 10.4%, respectively, for patients taking ibrutinib+BR versus 67.8% and 2.8% for people in the placebo+BR arm. At a pre-planned interim analysis earlier this year, an Independent Data Monitoring Committee (IDMC) recommended HELIOS be unblinded at that point and patients receiving placebo+BR be offered the option to receive ibrutinib as their next treatment once their CLL or SLL worsened.

"We are committed to a comprehensive and robust development program of IMBRUVICA to fully understand its safety and efficacy profile, alone and as a combination treatment, across a variety of hematologic malignancies," said Sen Zhuang, M.D., Ph.D., Vice President, Clinical Research, Janssen Oncology.

HELIOS is a randomized, double-blind, placebo-controlled, international, multicenter Phase 3 study conducted in 21 countries, which evaluated the safety and efficacy of ibrutinib 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 ibrutinib orally once daily and six cycles of BR, with ibrutinib or placebo continued until disease progression or unacceptable toxicity. The primary endpoint was IRC-assessed progression free survival (PFS) and key secondary endpoints included ORR per IRC, overall survival (OS), rate of minimal residual disease negative remissions (MRD- remissions) and safety. More information about the study can be found on www.clinicaltrials.gov.

Janssen Research & Development, LLC and Pharmacyclics LLC are continuing an extensive clinical development program for IMBRUVICA, including numerous Phase 3 studies in a variety of patient populations.

About CLL/SLL 
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.1,2 CLL is predominantly a disease of the elderly, with a median age of 71 at diagnosis.3 SLL is a slow-growing lymphoma biologically similar to CLL in which too many immature white blood cells cause lymph nodes to become larger than normal.4 IMBRUVICA is not approved to treat SLL.

About IMBRUVICA® (ibrutinib)
IMBRUVICA was one of the first therapies to receive U.S. approval after having received the FDA's Breakthrough Therapy Designation.5 IMBRUVICA works by blocking a specific protein called Bruton's tyrosine kinase (BTK).5 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.5,6 IMBRUVICA targets and blocks BTK, inhibiting cancer cell survival and spread.5 For more information, visit www.IMBRUVICA.com.

Additional Information about IMBRUVICA®  
INDICATIONS
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
    • Waldenstrom's macroglobulinemia (WM)
    • 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.

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 (e.g., 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* (57%, 52%, 43%), neutropenia* (47%, 51%, 44%), diarrhea (51%, 48%, 37%), anemia* (41%, 36%, 13%), fatigue (41%, 28%, 21%), musculoskeletal pain (37%, 28%**, NA***), bruising (30%, 12%**, 16%**), nausea (31%, 26%, 21%), upper respiratory tract infection (34%, 16%, 19%), and rash (25%, 24%**, 22%**).

*Based on adverse reactions and/or laboratory measurements (noted as platelets, neutrophils, or hemoglobin decreased).
