HORSHAM, Pa., Feb. 12, 2014 /PRNewswire/ -- Janssen Biotech, Inc. ["Janssen"] today announced the U.S. Food and Drug Administration (FDA) has approved IMBRUVICA™ (ibrutinib) capsules for the treatment of patients with chronic lymphocytic leukemia (CLL) who have received at least one prior therapy.1 IMBRUVICA was first approved in November 2013 for the treatment of patients with mantle cell lymphoma (MCL) who have received at least one prior therapy.1 Both indications are based on an overall response rate (ORR). An improvement in survival or disease-related symptoms has not been established.1
IMBRUVICA is the first once-daily, single-agent, oral Bruton's tyrosine kinase (BTK) inhibitor for patients with CLL who have received one prior therapy and is being jointly developed and commercialized by Janssen and Pharmacyclics, Inc. Both indications were granted priority review and were approved under the FDA's accelerated approval program; in addition, IMBRUVICA is one of the first medicines with the FDA's Breakthrough Therapy Designation to receive U.S. approval.
CLL is a slow-growing blood cancer of white blood cells called lymphocytes, most commonly B cells.2 CLL is an orphan disease (which is defined as a disease impacting fewer than 200,000 Americans3) and is primarily diagnosed in those over 70 years old.2 In the U.S., an estimated 16,000 people are diagnosed with CLL each year4 and it is estimated that nearly 4,600 will unfortunately die due to this disease.5 The U.S. prevalence of CLL is approximately 114,500 people.6
"CLL is a challenging disease and many physicians switch their patients from therapy to therapy as their disease relapses. There has been a significant need for new alternatives for these patients," said John C. Byrd, M.D., director, Division of Hematology, The Ohio State University Comprehensive Cancer Center – Arthur G. James Cancer Hospital & Richard J. Solove Research Institute and lead investigator for pivotal CLL trial PCYC-1102-CA.+ "The approval of IMBRUVICA provides a new, once-daily oral therapy option for physicians."
"The speed at which we were able to bring IMBRUVICA to this point epitomizes the sense of urgency that drives oncology drug developers to bring important new medicines to patients in need," said Craig Tendler, M.D., vice president, Late-Stage Development and Global Medical Affairs for Oncology, Janssen. "We're delighted and proud of today's approval, because it represents our commitment to making a difference for patients. We appreciate the ongoing collaboration between the companies and the FDA, which made this possible."
IMBRUVICA works by blocking a specific protein called BTK.1 Non-clinical studies have shown that blocking BTK inhibits the enzyme needed by the cancer to multiply and spread.1
IMBRUVICA in CLL
The safety and efficacy of IMBRUVICA in patients with relapsed or refractory CLL were evaluated in an open-label, multi-center Phase 1b/2 trial (PCYC-1102-CA) of 48 patients for a median treatment duration of 15.6 months.1 IMBRUVICA was administered at 420 mg once daily until disease progression or until no longer tolerated by the patient. The ORR and duration of response (DOR) were evaluated according to a modified version of the International Workshop on CLL (IWCLL) criteria by an Independent Review Committee. ORR was 58.3 percent of patients (95% confidence interval (CI) (%), 43.2, 72.4), all partial responses. None of the patients had a complete response. The DOR ranged from 5.6 to 24.2+ months. The median DOR was not reached.1
The Warnings and Precautions for IMBRUVICA include hemorrhage, infections, myelosuppression (reduced ability for the bone marrow to produce blood cells), renal toxicity, second primary malignancies and embryo-fetal toxicity.1 For more information about Warnings and Precautions, please see page four of this release.
The most common Grade 3 or 4 non-hematological adverse reactions (occurring in five percent or more of patients) were pneumonia (8%), hypertension (8%), atrial fibrillation (6.3%), sinusitis (6%), skin infection (6%), dehydration (6.4%) and musculoskeletal pain (6%). The most commonly occurring side effects (adverse reactions in 20 percent or more of CLL patients in the clinical trial) were thrombocytopenia*, diarrhea (63%), bruising (54%), neutropenia*, anemia*, upper respiratory tract infection (48%), fatigue (31%), musculoskeletal pain (27%), rash (27%), pyrexia (fever, 25%), constipation (23%), peripheral edema (23%), arthralgia (joint pain, 23%), nausea (21%), stomatitis (inflammation in the mouth, 21%), sinusitis (21%) and dizziness (21%).1 (Note: *Treatment-emergent decreases (all grades) of platelets (71%), neutrophils (54%) and hemoglobin (44%) were based on laboratory measurements per IWCLL criteria and adverse reactions.)
Five patients (10%) discontinued treatment due to adverse reactions in the clinical trial (N=48). These included three patients (6%) with infections and two patients (4%) with subdural hematomas. Adverse reactions leading to dose reduction occurred in 13 percent of patients.1
The recommended dose of IMBRUVICA for CLL is 420 mg (three 140 mg capsules) orally once daily.1
The IMBRUVICA PCYC-1102-CA CLL study was published online in The New England Journal of Medicine in June 2013.7
Janssen and Pharmacyclics are continuing an extensive clinical development program for IMBRUVICA, including Phase 3 study commitments in multiple patient populations.
IMPORTANT SAFETY INFORMATION
WARNINGS AND PRECAUTIONS
Hemorrhage – Five percent of patients with MCL and 6% of patients with CLL had Grade 3 or higher bleeding events (subdural hematoma, ecchymoses, gastrointestinal bleeding, and hematuria). Overall, bleeding events including bruising of any grade occurred in 48% of patients with MCL treated with 560 mg daily and 63% of patients with CLL treated at 420 mg daily.
The mechanism for the bleeding events is not well understood. IMBRUVICA™ may increase the risk of hemorrhage in patients receiving antiplatelet or anticoagulant therapies. 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 have occurred with IMBRUVICA™ therapy. At least 25% of patients with MCL and 35% of patients with CLL had infections Grade 3 or greater 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 with MCL and 35% of patients with CLL. These included neutropenia (29%), thrombocytopenia (17%) and anemia (9%) in patients with MCL and neutropenia (27%) and thrombocytopenia (10%) in patients with CLL. Monitor complete blood counts monthly.
Renal Toxicity – Fatal and serious cases of renal failure have occurred with IMBRUVICA™ therapy. Treatment-emergent increases in creatinine levels up to 1.5 times the upper limit of normal occurred in 67% of patients with MCL and 23% of patients with CLL. Increases in creatinine 1.5 to 3 times the upper limit of normal occurred in 9% of patients with MCL and 4% of patients with CLL. Periodically monitor creatinine levels. Maintain hydration.
Second Primary Malignancies – Other malignancies have occurred in 5% of patients with MCL and 10% of patients with CLL who have been treated with IMBRUVICA™. Four percent of patients with MCL had skin cancers and 1% had other carcinomas. Eight percent of patients with CLL had skin cancers and 2% had other carcinomas.
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.
