AbbVie will present results from several studies evaluating ibrutinib, an inhibitor of Bruton’s tyrosine kinase (BTK) being developed by Pharmacyclics, an AbbVie company, and Janssen Biotech, Inc., across a number of blood cancers. AbbVie will also present data on venetoclax, a BCL-2 inhibitor, being developed by AbbVie and Genentech, a member of the Roche Group. The scientific presentations describe the potential of ibrutinib and venetoclax in multiple hematologic malignancies, including chronic lymphocytic leukemia (CLL), multiple myeloma (MM) and acute myeloid leukemia (AML), among others. Data for elotuzumab, co-developed by Bristol-Myers Squibb and AbbVie, in MM will also be presented at the meeting.
"Every year the American Society of Hematology (ASH) (Free ASH Whitepaper) meeting marks the opportunity to show AbbVie’s success in advancing important treatments for people impacted by cancer," said Dr. Gary Gordon, vice president, oncology development, AbbVie. "Through our work with scientists, doctors and patients, AbbVie is presenting data highlighting progress in the discovery and development of new and promising therapies to treat blood cancers."

About IMBRUVICA (ibrutinib) in the U.S.
IMBRUVICA is a first-in-class, oral, once-daily therapy that inhibits a protein called Bruton’s tyrosine kinase (BTK). 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 to treat patients with CLL/SLL, patients with mantle cell lymphoma (MCL) who have received at least one prior therapy, and patients with Waldenström’s macroglobulinemia. Accelerated approval was granted for the MCL indication based on overall response rate. Continued approval for this indication may be contingent upon verification of clinical benefit in confirmatory trials.1
IMBRUVICA was one of the first medicines to receive U.S. FDA approval via the new Breakthrough Therapy Designation pathway.
IMBRUVICA is being studied alone and in combination with other treatments in several blood and solid tumor cancers. More than 6,000 patients have been treated with IMBRUVICA in clinical trials. Currently, 14 Phase 3 trials have been initiated with IMBRUVICA and more than 90 trials are registered on www.clinicaltrials.gov.
Patient Access to IMBRUVICA
AbbVie and Janssen strive to make access to IMBRUVICA easy by helping patients understand their insurance benefits for IMBRUVICA. The YOU&i Support Program is a personalized program that includes information on access and affordability, nurse call support and resources for patients being treated with IMBRUVICA. This includes the YOU&i Instant Savings program, which provides co-pay support to eligible commercially insured IMBRUVICA patients. Patients can access the program by contacting 1-877-877-3536, option 1 or by visiting View Source
The YOU&i Instant Savings program is not available for patients enrolled in Medicare or Medicaid. For a list of patient support organizations that may be able to provide financial support please visit: View Source
U.S. 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 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 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 postsurgery depending upon the type of surgery and the risk of bleeding.
Infections – Fatal and nonfatal infections have occurred with IMBRUVICA therapy. Grade 3 or greater infections occurred in 14% to 29% of patients. Cases of progressive multifocal leukoencephalopathy (PML) have occurred in patients treated with IMBRUVICA. Evaluate patients for fever and infections and treat appropriately.
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%) based on laboratory measurements occurred in patients treated with single agent 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, hypertension, 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. Atrial fibrillation should be managed appropriately and if it persists, consider the risks and benefits of IMBRUVICA treatment and follow dose modification guidelines.
Hypertension – Hypertension (range, 6% to 17%) has occurred in patients treated with IMBRUVICA with a median time to onset of 4.6 months (range, 0.03 to 22 months). Monitor patients for new-onset hypertension or hypertension that is not adequately controlled after starting IMBRUVICA. Adjust existing antihypertensive medications and/or initiate antihypertensive treatment as appropriate.
Second Primary Malignancies – Other malignancies (range, 5% to 16%) including non-skin carcinomas (range, 1% to 4%) have occurred in patients treated with IMBRUVICA. The most frequent second primary malignancy was non-melanoma skin cancer (range, 4% to 13%).
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. Advise women to avoid becoming pregnant while taking IMBRUVICA and for 1 month after cessation of therapy. 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 (?20%) in patients with B-cell malignancies (MCL, CLL/SLL, and WM) were neutropenia* (64%), thrombocytopenia* (63%), diarrhea (43%), anemia* (41%), musculoskeletal pain (30%), rash (29%), nausea (29%), bruising (29%), fatigue (27%), hemorrhage (21%), and pyrexia (21%).
*Based on adverse reactions and/or laboratory measurements (noted as platelets, neutrophils, or hemoglobin decreased).
The most common Grade 3 or 4 non-hematologic adverse reactions (?5%) in MCL patients were pneumonia (7%), abdominal pain (5%), atrial fibrillation (5%), diarrhea (5%), fatigue (5%), and skin infections (5%).
Approximately 6% (CLL), 14% (MCL), and 11% (WM) of patients had a dose reduction due to adverse reactions.
Approximately 4%-10% (CLL), 9% (MCL), and 6% (WM) of patients discontinued due to adverse reactions. Most frequent adverse reactions leading to discontinuation were pneumonia, hemorrhage, atrial fibrillation, rash and neutropenia (1% each) in CLL patients and subdural hematoma (1.8%) in MCL patients.
DRUG INTERACTIONS
CYP3A Inhibitors – Avoid coadministration with strong and moderate CYP3A inhibitors. If a moderate CYP3A inhibitor must be used, reduce the IMBRUVICA dose.
CYP3A Inducers – Avoid coadministration 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.

About Venclexta (venetoclax) in the U.S.
Venclexta (venetoclax) is an oral B-cell lymphoma-2 (BCL-2) inhibitor indicated in the U.S. for the treatment of patients with relapsed/refractory CLL with 17p deletion, as detected by an FDA-approved test.3 The BCL-2 protein prevents apoptosis (programmed cell death) of some cells, including lymphocytes, and can be overexpressed in CLL cells.3 Venclexta is designed to selectively inhibit the BCL-2 protein.3 Venclexta was developed in collaboration with Genentech and Roche.
Together, the companies are committed to BCL-2 research with venetoclax, which is currently being evaluated in Phase 3 clinical trials for the treatment of relapsed/refractory and first-line CLL, along with early phase studies in several cancers.
Venetoclax is under evaluation by health authorities in multiple countries, and is currently approved in Argentina, Puerto Rico and Canada.
