RARITAN, NJ, September 26, 2016 – Janssen Research & Development, LLC announced today that a supplemental New Drug Application (sNDA) for ibrutinib (IMBRUVICA®) has been submitted to the U.S. Food and Drug Administration (FDA) for the treatment of patients with marginal zone lymphoma (MZL) who require systemic therapy. The filing is based on data from the multi-center, open-label Phase 2 PCYC-1121 trial assessing the use of ibrutinib, a BTK inhibitor, in patients with MZL who have received at least one prior therapy. IMBRUVICA is jointly developed and commercialized by Janssen and Pharmacyclics LLC, an AbbVie company.
“We are encouraged by the results of this study of ibrutinib in yet another type of B-cell malignancy,” said Peter F. Lebowitz, M.D., Ph.D., Global Oncology Head, Janssen. “This FDA submission represents an exciting and important step towards a potential new treatment option for MZL patients who currently have a great unmet need. Currently there are no therapies approved for this rare form of cancer.”
The PCYC-1121 international trial enrolled 63 patients with MZL who had received at least one prior therapy, including splenic MZL (SMZL), nodal MZL (NMZL) and extranodal MZL (EMZL). Patients received ibrutinib 560mg orally, once daily until progression or unacceptable toxicity. The primary endpoint of the study was overall response rate as assessed by an Independent Review Committee. Key secondary endpoints included duration of response and overall response rate. The data have been submitted for publication in a peer-reviewed journal and presentation at an upcoming medical conference. More information about the study can be found on www.clinicaltrials.gov (NCT01980628).
IMBRUVICA is currently approved to treat patients with chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) including patients with 17p deletion, patients with mantle cell lymphoma (MCL) who have received at least one prior therapy and patients with Waldenström’s macroglobulinemia (WM). Accelerated approval was granted for MCL based on overall response rate. Continued approval for this indication may be contingent upon verification of clinical benefit in confirmatory trials.
Janssen and Pharmacyclics are continuing an extensive clinical development program for IMBRUVICA, including Phase 3 study commitments in multiple patient populations.
About Marginal Zone Lymphoma (MZL)
MZL is a B-cell lymphoma arising from white blood cells (lymphocytes) at the margins, or edges of lymph nodes and various tissues, including the stomach, salivary glands, thyroid gland, eyes, lungs and spleen.1 MZL accounts for approximately 12 percent of all cases of non-Hodgkin lymphoma in adults, and the median age of diagnosis is 65 years old. There are currently no approved treatments or established standards of care specifically indicated for patients with MZL.
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).2 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.3 IMBRUVICA targets and blocks BTK, inhibiting cancer cell survival and spread.

- Waldenström’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 (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 (eg, 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 (eg, 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.
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.
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.
Hepatic Impairment - Avoid use in patients with moderate or severe baseline hepatic impairment. In patients with mild impairment, reduce IMBRUVICA® dose.
