RARITAN, NJ, November 19, 2013 – Janssen Research & Development, LLC (Janssen) announced that data related to three Janssen compounds have been selected for presentation at the 55th American Society of Hematology (ASH) Annual Meeting in New Orleans, LA. Nine pieces of company-sponsored research will be presented out of a total of nearly 50 abstracts involving Janssen hematology compounds. Data include presentations on the investigational use of ibrutinib, recently approved by the U.S. Food and Drug Administration; siltuximab, an investigational anti Interleukin-6 (IL-6) chimeric monoclonal antibody being studied in multicentric Castleman disease (MCD); and daratumumab, an investigational human CD38 monoclonal antibody being studied in multiple myeloma and other B-cell malignancies.
“Therapies for hematologic malignancies are the cornerstone of our broad oncology portfolio at Janssen R&D,” said Peter F. Lebowitz, M.D., Ph.D., global oncology therapeutic area head, Janssen. “It’s rewarding to have such a comprehensive array of data presented at ASH, across our oncology compounds, particularly as we look ahead to potential regulatory milestones for siltuximab and daratumumab, and following the recent U.S. FDA approval of ibrutinib.”

About Ibrutinib
Janssen Biotech, Inc. and Pharmacyclics, Inc. entered a collaboration and license agreement in December 2011 to jointly develop and commercialize ibrutinib. On November 13, 2013, the U.S. Food and Drug Administration granted approval for the use of ibrutinib in patients with mantle cell lymphoma (MCL) who have received at least one prior therapy. This indication is based on overall response rate (ORR). An improvement in survival or disease-related symptoms has not been established. Ibrutinib works by blocking a specific protein called Bruton’s tyrosine kinase (BTK).[1] For more information, visit www.IMBRUVICA.com. The effectiveness and safety of ibrutinib alone or in combination with other treatments is being studied in several B-cell malignancies. Details about the complete ibrutinib clinical program are posted on clinicaltrials.gov.
About Siltuximab
Siltuximab is an investigational, anti Interleukin-6 (IL-6) chimeric monoclonal antibody that targets and binds to human IL-6. IL-6 is a multifunctional cytokine produced by various cells such as T cells, B cells, monocytes, fibroblasts and endothelial cells.[2] Dysregulated, or imbalanced, overproduction of IL-6 from activated B cells in affected lymph nodes has been implicated in the pathogenesis of multicentric Castleman disease (MCD), a rare blood disorder.2 Information about ongoing studies with siltuximab can be found on clinicaltrials.gov.
On September 3, 2013, Janssen announced simultaneous submissions of a Biologic License Application (BLA) to the United States Food and Drug Administration (FDA) and a Marketing Authorization Application (MAA) to the European Medicines Agency (EMA) for siltuximab for the treatment of patients with MCD who are HIV-negative and HHV-8-negative. Siltuximab has been granted orphan drug status in MCD in the U.S. and EU.
About Daratumumab
In August 2012, Genmab granted Janssen Biotech, Inc. an exclusive worldwide license to develop and commercialize daratumumab. Daratumumab is an investigational human monoclonal antibody (mAb) with broad spectrum cytotoxic activity. It targets the CD38 molecule, which is highly expressed on the surface of multiple myeloma cells and may also have potential in other cancers on which CD38 is expressed. In May 2013, daratumumab was granted Breakthrough Therapy Designation by the FDA for the treatment of patients with multiple myeloma who have received at least three prior lines of therapy including a proteasome inhibitor (PI) and an immunomodulatory agent (IMiD), or who are double refractory to a PI and IMiD.

Additional Information about IMBRUVICA
INDICATION – IMBRUVICA is indicated for the treatment of patients with mantle cell lymphoma (MCL) who have received at least one prior therapy. This indication is based on overall response rate. An improvement in survival or disease-related symptoms has not been established.
IMPORTANT SAFETY INFORMATION
WARNINGS AND PRECAUTIONS
Hemorrhage – Five percent (5%) of patients with MCL had Grade 3 or higher bleeding events (subdural hematoma, gastrointestinal bleeding, and hematuria). Bleeding events including bruising of any grade occurred in 48% of patients with MCL treated with 560 mg daily. The mechanism for the bleeding events is not well understood. Consider the benefit-risk of ibrutinib in patients requiring antiplatelet or anticoagulant therapies and the benefit-risk of withholding ibrutinib 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. At least 25% of patients with MCL had infections ≥ Grade 3, according to 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. These included neutropenia (29%), thrombocytopenia (17%) and anemia (9%). Monitor complete blood counts monthly.
Renal Toxicity – Fatal and serious cases of renal failure have occurred. Treatment-emergent increases in creatinine levels up to 1.5 times the upper limit of normal occurred in 67% of patients and from 1.5 to 3 times the upper limit of normal in 9% of patients. Periodically monitor creatinine levels. Maintain hydration.
Second Primary Malignancies – Other malignancies (5%) have occurred in patients with MCL who have been treated with IMBRUVICA, including skin cancers (4%), and other carcinomas (1%).
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 commonly occurring adverse reactions (≥ 20%) in the clinical trial were thrombocytopenia*, diarrhea (51%), neutropenia*, anemia*, fatigue (41%), musculoskeletal pain (37%), peripheral edema (35%), upper respiratory tract infection (34%), nausea (31%), bruising (30%), dyspnea (27%), constipation (25%), rash (25%), abdominal pain (24%), vomiting( 23%) and decreased appetite (21%).
* Treatment-emergent decreases (all grades) of platelets (57%), neutrophils (47%) and hemoglobin (41%) were based on laboratory measurements and adverse reactions.
The most common Grade 3 or 4 non-hematological adverse reactions (≥ 5%) were: pneumonia (7%), abdominal pain (5%), atrial fibrillation, diarrhea (5%), fatigue (5%), and skin infections (5%). Treatment-emergent Grade 3 or 4 cytopenias were reported in 41% of patients.
Ten patients (9%) discontinued treatment due to adverse reactions in the trial (N=111).
The most frequent adverse reaction leading to treatment discontinuation was subdural hematoma (1.8%). Adverse reactions leading to dose reduction occurred in 14% of patients.
Drug Interactions:
CYP3A Inhibitors – Avoid concomitant administration with strong or moderate inhibitors of CYP3A. If a moderate CYP3A inhibitor must be used, reduce the IMBRUVICA dose.
CYP3A Inducers – Avoid co-administration with strong CYP3A inducers.
Special Populations – Hepatic Impairment – Avoid use in patients with baseline hepatic impairment.
