This Changes Everything: Approval of Imbruvica (ibrutinib) for Frontline Use in CLL (chronic lymphocytic leukemia)

This is big news in stark contrast to the preliminary NICE recommendation to note approve ibrutininb  for relapsed and refractory patients in the UK despite approval in almost 50 other countries.

Here is one of the many links on this story. Here's another.

On the other side of the ocean in the USA, in stark contrast,  there was good news of FDA frontline approval of ibrutinib. This changes everything. I will comment more on this later.

Here is the official press release from Abbvie for your review and appraisal:

PRESS RELEASE

IMBRUVICA® (ibrutinib) Approved by U.S. FDA for the First-line Treatment of Chronic Lymphocytic Leukemia

         ·  Approval based on data from the Phase 3 RESONATETM-2 trial showing an 84% reduction in the risk of progression or death with IMBRUVICA compared to chlorambucil 


         ·  First FDA-approved chemotherapy-free treatment option for first-line CLL patients 


         ·  This is the 5th treatment indication for IMBRUVICA 
NORTH CHICAGO, Ill., Mar. 4, 2016 – AbbVie (NYSE: ABBV), a global biopharmaceutical company, today announced the U.S. Food and Drug Administration (FDA) approved IMBRUVICA® (ibrutinib) as a first-line treatment for patients with chronic lymphocytic leukemia (CLL).1 The approval is based on data from the randomized, multi-center, open-label Phase 3 RESONATETM-2 (PCYC-1115) trial, which evaluated the use of IMBRUVICA versus chlorambucil in 269 treatment-naïve patients with CLL or small lymphocytic lymphoma (SLL) aged 65 years or older. The RESONATE-2 data were previously presented at the American Society of Hematology (ASH) Annual Meeting in December 2015 and also simultaneously published in The New England Journal of Medicine. IMBRUVICA is jointly developed and commercialized by Pharmacyclics LLC, an AbbVie company and Janssen Biotech, Inc. 
“This approval represents a significant leap forward for patients diagnosed with CLL who may want to consider an alternative first-line treatment to traditional chemotherapy,” said Michael Severino, M.D., executive vice president, research and development and chief scientific officer, AbbVie. “AbbVie is committed to making significant improvements in the lives of patients with hematologic malignancies and will continue to explore ways to improve treatment options for patients.” 
The prevalence of CLL is approximately 115,000 patients in the U.S.2 with approximately 15,000 newly diagnosed patients every year.3 CLL is a disease of elderly patients, with an average diagnosis age of 71.3 
The National Comprehensive Cancer Network (NCCN) recently published an update to its clinical practice guidelines for non-Hodgkin’s lymphomas, granting IMBRUVICA a category 1 recommendation for certain CLL patients, the highest recommendation assigned by the organization. Specifically, NCCN recommends IMBRUVICA as a first-line treatment option for frail CLL patients with significant comorbidities, as well as for CLL patients with or without del 17p or the genetic mutation TP53 who are 70 years or older, or younger patients with significant comorbidities. The NCCN guidelines inform prescribing and reimbursement practices in many institutions in the U.S. and internationally.

“The progression-free survival data seen in these previously untreated CLL patients are strong and encouraging,” said Dr. Jan Burger, M.D., Ph.D., Associate Professor, Department of Leukemia, Division of Cancer Medicine, The University of Texas MD Anderson Cancer Center, Houston, TX and the RESONATE-2 lead study investigator.* “This is especially important for first-line CLL patients, when considering the safety profile. This treatment represents another option for these patients.”

IMBRUVICA is now approved to treat CLL patients regardless of their treatment history (treatment-naïve and previously-treated patients). In addition, IMBRUVICA is approved to treat high-risk CLL patients with del 17p,1 a genetic aberration that occurs when part of chromosome 17, the location of the tumor suppressor gene `

IMBRUVICA significantly prolonged progression-free survival (PFS; primary endpoint) as determined by an Independent Review Committee (IRC), reducing the risk of progression or death by 84% versus chlorambucil (hazard ratio [HR], 0.161 [95% confidence interval: 0.091, 0.283]; median PFS: not reached for IMBRUVICA vs. 18.9 months [95% confidence interval: 14.1, 22.0] for chlorambucil).1 IMBRUVICA was also associated with a significantly higher IRC-assessed overall response rate (ORR: a composite of complete and partial responses; 82.4% vs. 35.3%; P<0 .0001="" chlorambucil.="" span="" versus="">1 Five patients (3.7 percent) in the IMBRUVICA arm achieved a complete response, compared to two patients (1.5 percent) in the chlorambucil arm.1

The safety of IMBRUVICA in this patient population was consistent with previously reported studies. The adverse reactions (AR) reported in the U.S. Prescribing Information reflect exposure to IMBRUVICA with a median duration of 17.4 months versus a median exposure to chlorambucil of 7.1 months: nearly 2.5 times longer exposure for IMBRUVICA. Warnings and Precautions include hemorrhage, infections, cytopenias, atrial fibrillation, hypertension, second primary malignancies, embryo-fetal toxicity and tumor lysis syndrome. The most commonly occurring adverse reactions of all Grades in CLL patients treated with IMBRUVICA in the RESONATE-2 trial (>20%) were diarrhea, musculoskeletal pain, cough and rash.

About the RESONATE-2 Study

RESONATE-2 is a Pharmacyclics-sponsored study which enrolled 269 treatment-naïve patients with CLL or SLL aged 65 years or older in the U.S., EU and other regions. Patients were randomized to receive either IMBRUVICA 420 mg orally, once daily until progression or unacceptable toxicity, or chlorambucil on days 1 and 15 of each 28-day cycle for up to 12 cycles. The starting dose for chlorambucil in Cycle 1 was 0.5 mg/kg and was increased based on tolerability in Cycle 2 by increments of 0.1 mg/kg to a maximum of 0.8 mg/kg. The primary endpoint of the study was PFS as assessed by an IRC according to the International Workshop on

About IMBRUVICA

IMBRUVICA is a first-in-class, oral, once-daily therapy that inhibits a protein called Bruton's tyrosine kinase (BTK).1 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.1,4 IMBRUVICA blocks signals that tell malignant B cells to multiply and spread uncontrollably.1

IMBRUVICA is approved to treat patients with CLL, 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.

IMPORTANT SAFETY INFORMATION WARNINGS AND PRECAUTIONS

AbbVie Inc. +1 (847) 938-9190 1 North Waukegan Road abbvie.com
North Chicago, IL 60064

Hemorrhage - Fatal bleeding events have occurred in patients treated with IMBRUVICAÒ. 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 IMBRUVICAÒ.

The mechanism for the bleeding events is not well understood. IMBRUVICAÒ 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 IMBRUVICAÒ 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 IMBRUVICAÒ therapy. Grade 3 or greater infections occurred in 14% to 26% of patients. Cases of progressive multifocal leukoencephalopathy (PML) have occurred in patients treated with IMBRUVICAÒ. 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%) occurred in patients treated with IMBRUVICAÒ. Monitor complete blood counts monthly.

Atrial Fibrillation - Atrial fibrillation and atrial flutter (range, 6% to 9%) have occurred in patients treated with IMBRUVICAÒ, 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 IMBRUVICAÒ treatment and dose modification.

Hypertension - Hypertension (range, 6% to 17%) has occurred in patients treated with IMBRUVICA® with a median time to onset of 4.5 months (range, 0.03 to 18.40 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 IMBRUVICAÒ. 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 IMBRUVICAÒ 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, IMBRUVICAÒ can cause fetal harm when administered to a pregnant woman. Advise women to avoid becoming pregnant while taking IMBRUVICAÒ 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, WM) were thrombocytopenia* (57%, 53%, 43%), diarrhea (51%, 48%, 37%), anemia* (41%, 37%, 13%), neutropenia* (47%, 46%, 44%), musculoskeletal pain (37%, 32%†, NA‡), fatigue (41%, 29%, 21%), bruising (30%, 25%†, 16%†), nausea (31%, 24%, 21%), rash (25%, 23%†, 22%†), and upper respiratory tract infection (34%, 19%, 19%).

*Based on adverse reactions and/or laboratory measurements (noted as platelets, neutrophils, or hemoglobin decreased). †Includes multiple ADR terms.
‡Not applicable; no associated ADRs.

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 4% (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, subdural hematomas, and atrial fibrillation (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 IMBRUVICAÒ dose.
CYP3A Inducers - Avoid coadministration with strong CYP3A inducers.
