The approval was based on the results of a multi-center, international, single-arm trial of 111 patients with previously treated mantle cell lymphoma. Tumor response was assessed according to the revised
Safety was evaluated in the same 111 patients. The most common Grade 3 or 4 non-hematological adverse reactions (greater than or equal to 5%) were: pneumonia (7%), abdominal pain (5%), atrial fibrillation, diarrhea (5%), fatigue (5%), and skin infections (5%). Five percent of patients had Grade 3 or higher bleeding events (subdural hematoma, gastrointestinal bleeding, and hematuria). Treatment-emergent Grade 3 or 4 cytopenias (adverse reactions and laboratory abnormalities combined) were reported in 41% of patients. The Warnings and Precautions listed in the Prescribing Information include hemorrhage, infections, myelosuppression, renal toxicity, second primary malignancies and embryo-fetal toxicity.
Ten patients (9%) discontinued treatment due to adverse reactions in the trial.
Adverse reactions leading to dose reduction occurred in 14% of patients.
The recommended dose in this patient population is 560 mg (four 140 mg capsules) orally once daily.1

"Breakthrough Therapy Designation is intended to speed up the development and review of treatments to help address serious or life-threatening diseases. It is gratifying to see this early example of the new pathway meeting its intention — getting a promising treatment to patients who are waiting for new options," said Dr.

INDICATION - IMBRUVICA (ibrutinib) 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 - 5% of patients with MCL had greater than or equal to Grade 3 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 greater than or equal to 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 (greater than or equal to 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 (greater than or equal to 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.
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.

About Mantle Cell Lymphoma (MCL)
B cells are the immune cells in the body that are responsible for producing antibodies to fight infections and provide long term immunity. MCL is a blood cancer of the B cells; it is an aggressive type of B-cell non-Hodgkin lymphoma (NHL) that usually occurs in older adults.6 The disease typically involves the lymph nodes, but can spread to other tissues, such as bone marrow, liver, spleen, and gastrointestinal tract. Patients survive an average of five years.7 MCL is classified as an orphan or rare disease, meaning it affects fewer than 200,000 Americans.8
IMBRUVICA is indicated for the treatment of patients with mantle cell lymphoma who have received at least one prior therapy.1 This indication is based on overall response rate (ORR). An improvement in survival or disease-related symptoms has not been established. For more information about IMBRUVICA, including the full prescribing information, please visit www.IMBRUVICA.com. IMBRUVICA is a first in class, oral therapy and is a new agent that inhibits a protein called Bruton's tyrosine kinase (BTK).1 BTK is a key signaling molecule of the B-cell receptor signaling complex that plays an important role in the survival of malignant B cells.2,3,4 IMBRUVICA blocks signals that tell malignant B cells to grow and divide uncontrollably.1,5 It is one of the first medicines to file for
To date, nine Phase III trials have been initiated with ibrutinib and a total of 37 trials are currently registered on www.clinicaltrials.gov.
