U.S. FDA Approves IMBRUVICA(R) (ibrutinib) Plus Obinutuzumab as First Non-Chemotherapy Combination Regimen for Treatment-Na´ve Patients with Chronic Lymphocytic LeukemiaPatients treated with IMBRUVICA plus obinutuzumab experienced a 77 percent reduction in risk of progression or death compared to chlorambucil plus obinutuzumab
Approval broadens the label in frontline CLL and represents the tenth FDA approval for IMBRUVICA
IMBRUVICA label now includes additional monotherapy long-term follow-up data
HORSHAM, Pa., Jan. 28, 2019 -- (Healthcare Sales & Marketing Network) -- The Janssen Pharmaceutical Companies of Johnson & Johnson announced today the U.S. Food and Drug Administration (FDA) approval of IMBRUVICA« (ibrutinib) in combination with obinutuzumab in treatment-na´ve patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL), the most common form of leukemia in adults.1 This is the first approval for a non-chemotherapy combination regimen for treatment-na´ve patients with CLL/SLL, and marks the tenth FDA approval for IMBRUVICA since its U.S. launch in November 2013. The approval expands the label for IMBRUVICA in frontline CLL/SLL beyond its use as a monotherapy to include combination use with obinutuzumab. IMBRUVICA, a Bruton's tyrosine kinase (BTK) inhibitor, is jointly developed and commercialized by Janssen Biotech, Inc. and Pharmacyclics LLC, an AbbVie company.
"In just a few years, IMBRUVICA has become an important treatment for chronic lymphocytic leukemia. IMBRUVICA as a single agent ľ and now as a combination with obinutuzumab ľ provides patients with CLL with an alternative to frontline treatment with chemoimmunotherapy," said Carol Moreno, M.D., Ph.D., Consultant Hematologist, Hospital de la Santa Creu Sant Pau, Autonomous University of Barcelona, Barcelona, Spain, and lead investigator of the iLLUMINATE study.
This approval is based on results from the Phase 3 iLLUMINATE study (PCYC-1130). At a median follow-up of 31 months, IMBRUVICA plus obinutuzumab showed a significant improvement in Independent Review Committee (IRC)-evaluated progression-free survival compared with chlorambucil plus obinutuzumab (median not evaluable [NE] vs. 19 months; hazard ratio [HR] 0.23; 95 percent confidence interval [CI]: 0.15-0.37; P<0.0001), with a 77 percent reduction in risk of progression or death. Patients with high-risk disease (17p deletion/TP53 mutation, 11q deletion, or unmutated IGHV) treated with IMBRUVICA plus obinutuzumab experienced an 85 percent reduction in risk of progression or death (HR 0.15; 95 percent CI: 0.09-0.27). The IRC-evaluated overall response rate was 89 percent in the IMBRUVICA plus obinutuzumab arm versus 73 percent in the chlorambucil plus obinutuzumab arm. The data were recently presented in an oral session at the 2018 American Society of Hematology (ASH) Annual Meeting and simultaneously published in The Lancet Oncology.
"This label update builds upon the established efficacy and safety of IMBRUVICA in the frontline treatment of patients with CLL/SLL, as a monotherapy or in combination with other treatments," said Craig Tendler, M.D., Vice President, Clinical Development and Global Medical Affairs, Janssen Research & Development, LLC. "This milestone represents our continued commitment to develop IMBRUVICA-based, non-chemotherapy regimens to address the clinical needs of patients living with CLL/SLL."
The FDA also updated the IMBRUVICA label to include additional long-term efficacy data supporting its use as a monotherapy in CLL/SLL, with approximately five years of follow-up from the Phase 3 RESONATEÖ (PCYC-1112) and RESONATEÖ-2 (PCYC-1115, PCYC-1116) international studies.
Warnings and Precautions include hemorrhage, infections, cytopenias, cardiac arrhythmias, hypertension, second primary malignancies, tumor lysis syndrome, and embryo-fetal toxicity. The most common adverse reactions (occurring in 20 percent or more of patients) of all grades in patients treated with IMBRUVICA plus obinutuzumab in the iLLUMINATE study were neutropenia (48 percent), thrombocytopenia (36 percent), rash (36 percent), diarrhea (34 percent), musculoskeletal pain (33 percent), bruising (32 percent), cough (27 percent), infusion related reaction (25 percent), hemorrhage (25 percent), and arthralgia (22 percent).
The recommended dose of IMBRUVICA for CLL/SLL is 420 mg orally once daily until disease progression or unacceptable toxicity as a single agent or in combination with obinutuzumab or bendamustine and rituximab (BR). When administering IMBRUVICA in combination with rituximab or obinutuzumab, doctors should consider administering IMBRUVICA prior to rituximab or obinutuzumab when given on the same day.
IMBRUVICA (ibrutinib) is a once-daily oral medicine that works differently than chemotherapy as it blocks the Bruton's tyrosine kinase (BTK) protein. The BTK protein sends important signals that tell B cells to mature and produce antibodies. BTK signaling is needed by specific cancer cells to multiply and spread.2,3 By blocking BTK, IMBRUVICA may help move abnormal B cells out of their nourishing environments in the lymph nodes, bone marrow, and other organs.4,5
IMBRUVICA is approved in more than 90 countries, and, to date, has been used to treat more than 135,000 patients worldwide across approved indications. It was first approved by the U.S. Food and Drug Administration (FDA) in November 2013, and today is indicated in six disease areas, including five hematologic cancers ľ chronic lymphocytic leukemia (CLL) with or without 17p deletion (del17p), small lymphocytic lymphoma (SLL) with or without del17p, Waldenstr÷m's macroglobulinemia (WM), previously-treated patients with mantle cell lymphoma (MCL)*, previously-treated patients with marginal zone lymphoma (MZL) who require systemic therapy and have received at least one prior anti-CD20-based therapy* ľ and previously-treated patients with chronic graft-versus-host disease (cGVHD) after failure of one or more lines of systemic therapy.5
IMBRUVICA is the first and only FDA-approved medicine in WM, MZL* and cGVHD. IMBRUVICA has been granted four Breakthrough Therapy Designations by the FDA, and it was one of the first medicines to receive U.S. approval through the Breakthrough Therapy Designation.
* Accelerated approval was granted for MCL and MZL based on overall response rate. Continued approval for MCL and MZL may be contingent upon verification and description of clinical benefit in confirmatory trials.
IMBRUVICA is a comprehensively studied molecule in the oncology industry. The robust clinical oncology development program includes more than 150 active clinical trials studying IMBRUVICA alone and in combination with other medicines in several blood cancers and other serious diseases.

IMPORTANT SAFETY INFORMATION
WARNINGS AND PRECAUTIONS
Hemorrhage: Fatal bleeding events have occurred in patients treated with IMBRUVICA«. Grade 3 or higher bleeding events (intracranial hemorrhage [including subdural hematoma], gastrointestinal bleeding, hematuria, and post procedural hemorrhage) have occurred in 3% of patients, with fatalities occurring in 0.3% of 1,124 patients exposed to IMBRUVICA« in clinical trials. Bleeding events of any grade, including bruising and petechiae, occurred in 44% 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 and patients should be monitored for signs of bleeding.
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 (including bacterial, viral, or fungal) have occurred with IMBRUVICA« therapy. Grade 3 or greater infections occurred in 24% of 1,124 patients exposed to IMBRUVICA« in clinical trials. Cases of progressive multifocal leukoencephalopathy (PML) and Pneumocystis jirovecii pneumonia (PJP) have occurred in patients treated with IMBRUVICA«. Consider prophylaxis according to standard of care in patients who are at increased risk for opportunistic infections.
Monitor and evaluate patients for fever and infections and treat appropriately.
Cytopenias: Treatment-emergent Grade 3 or 4 cytopenias including neutropenia (23%), thrombocytopenia (8%), and anemia (3%) based on laboratory measurements occurred in patients with B‑cell malignancies treated with single agent IMBRUVICA«.
Monitor complete blood counts monthly.
Cardiac Arrhythmias: Fatal and serious cardiac arrhythmias have occurred with IMBRUVICA« therapy. Grade 3 or greater ventricular tachyarrhythmias occurred in 0.2% of patients, and Grade 3 or greater atrial fibrillation and atrial flutter occurred in 4% of 1,124 patients exposed to IMBRUVICA« in clinical trials. These events have occurred particularly in patients with cardiac risk factors, hypertension, acute infections, and a previous history of cardiac arrhythmias.
Periodically monitor patients clinically for cardiac arrhythmias. Obtain an ECG for patients who develop arrhythmic symptoms (e.g., palpitations, lightheadedness, syncope, chest pain) or new onset dyspnea. Manage cardiac arrhythmias appropriately, and if it persists, consider the risks and benefits of IMBRUVICA« treatment and follow dose modification guidelines.
Hypertension: Hypertension of any grade occurred in 12% of 1,124 patients treated with IMBRUVICA« in clinical trials. Grade 3 or greater hypertension occurred in 5% of patients with a median time to onset of 5.9 months (range, 0.03 to 24 months).
Monitor blood pressure in patients treated with IMBRUVICA« and initiate or adjust anti-hypertensive medication throughout treatment with IMBRUVICA« as appropriate.
Second Primary Malignancies: Other malignancies (10%) including non-skin carcinomas (4%) have occurred in 1,124 patients treated with IMBRUVICA« in clinical trials. The most frequent second primary malignancy was non-melanoma skin cancer (6%).
Tumor Lysis Syndrome: Tumor lysis syndrome has been infrequently reported with IMBRUVICA« therapy. Assess the baseline risk (e.g., high tumor burden) and take appropriate precautions.
Monitor patients closely and treat as appropriate.
Embryo-Fetal Toxicity: Based on findings in animals, IMBRUVICA« can cause fetal harm when administered to a pregnant woman.
