LONDON, SUNNYVALE, Calif. and RARITAN, N.J., Nov. 4, 2014 /PRNewswire/ -- AstraZeneca, Pharmacyclics, Inc. and Janssen Research & Development LLC ("Janssen") today announced they have entered into a clinical trial collaboration to evaluate the efficacy and safety of AstraZeneca's investigational anti-PD-L1 immune checkpoint inhibitor, MEDI4736, in combination with IMBRUVICA® (ibrutinib), an oral Bruton's tyrosine kinase inhibitor, co-developed and co-commercialized by Pharmacyclics and Janssen Biotech, Inc. The study will assess the combination as a treatment for patients with hematologic cancers including Diffuse Large B-Cell Lymphoma and Follicular Lymphoma, which are investigational uses for both compounds.
MEDI4736 blocks the signals that help tumors avoid detection by the immune system, countering the tumor's immune-evading tactics. Ibrutinib blocks signals that tell malignant B cells (white blood cells that produce antibodies) to multiply and spread uncontrollably. Preclinical evidence suggests that the combination of these two agents may lead to an enhanced anti-tumor immune response.
The Phase I part of the trial is expected to establish a recommended dose regimen for the combination of MEDI4736 and ibrutinib, and the Phase II part of the study will assess the safety and efficacy of the investigational combination. Under the terms of the agreement, the trial will be conducted by Pharmacyclics. The financial terms of the agreement have not been disclosed.
Briggs Morrison, Executive Vice President, Global Medicines Development & Chief Medical Officer, AstraZeneca, said: "We are committed to progressing our strong immuno-oncology pipeline as rapidly as possible. Our partnership with Pharmacyclics and Janssen supports our exploration of the potential of anti-PD-L1 in hematological cancers and is further evidence of our belief that combination therapies have the potential to be one of the most effective ways of treating cancer."
"We are delighted by our strategic collaboration with AstraZeneca as we explore the potential of IMBRUVICA in combination with immunotherapy to address a variety of hematologic cancers in which we already have deep experience and an ongoing scientific interest," said Bob Duggan, Chairman & CEO, Pharmacyclics. "We look forward to working with our partners as we advance our understanding of different ways by which to continue to evolve treatment paradigms and expand treatment options for patients with certain B-cell malignancies."
"Cancer drug development is at one of its most exciting, productive periods in history," said Peter Lebowitz, MD, PhD, Global Oncology Head, Janssen. "This collaboration reflects the common goal of all three companies to better understand new treatment options and combinations – with the ultimate goal of making a difference to the lives of people with hematologic malignancies."
MEDI4736 is an investigational human monoclonal antibody directed against programmed cell death ligand 1 (PD-L1). Signals from PD-L1 help tumors avoid detection by the immune system. MEDI4736 blocks these signals, countering the tumor's immune-evading tactics. MEDI4736 is being developed, alongside other immunotherapies, to empower the patient's immune system and attack the cancer.
MEDI4736 is in development as monotherapy in solid tumors, with Phase III clinical trials due to commence in 2014 for patients with non-small cell lung cancer and squamous cell carcinoma of the head of neck. AstraZeneca and MedImmune, its biologics research and development arm, also have a broad program of immuno-oncology combination trials underway, including MEDI4736 + tremelimumab (CTLA-4), MEDI4736 + MEDI0680 (PD-1) and MEDI4736 + MEDI6469 (OX40) and MEDI4736 + IRESSA (epidermal growth factor receptor-tyrosine kinase inhibitor).
IMBRUVICA® (ibrutinib) 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. IMBRUVICA blocks signals that tell malignant B cells to multiply and spread uncontrollably.
IMBRUVICA was one the first medicines to receive U.S. FDA approval via the new Breakthrough Therapy Designation pathway, and is the only product to have received three Breakthrough Therapy Designations. IMBRUVICA is jointly developed and commercialized by Janssen Biotech, Inc. and Pharmacyclics.
IMBRUVICA is indicated to treat people with:
- Mantle cell lymphoma (MCL) who have received at least one prior therapy
- Accelerated approval was granted for this indication based on overall response rate. Improvements in survival or disease-related symptoms have not been established. Continued approval for this indication may be contingent upon verification of clinical benefit in confirmatory trials.
- Chronic lymphocytic leukemia (CLL) who have received at least one prior therapy
- Chronic lymphocytic leukemia (CLL) with 17p deletion
IMPORTANT SAFETY INFORMATION
WARNINGS AND PRECAUTIONS
Hemorrhage - Grade 3 or higher bleeding events (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 anti-platelet or anti-coagulant 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. Twenty-five percent of patients with MCL and 26% of patients with CLL had Grade 3 or greater NCI Common Terminology Criteria for Adverse Events (CTCAE). Monitor patients for fever and infections and evaluate promptly.
Cytopenias - Treatment-emergent Grade 3 or 4 cytopenias including neutropenia (range, 23 to 29%), thrombocytopenia (range, 5 to 17%), and anemia (range, 0 to 9%) occurred in patients treated with 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, 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. If atrial fibrillation persists, consider the risks and benefits of IMBRUVICA® treatment and dose modification.
Second Primary Malignancies - Other malignancies (range, 5 to 10%) including carcinomas (range, 1 to 3%) have occurred in patients treated with IMBRUVICA®. The most frequent second primary malignancy was non-melanoma skin cancer (range, 4 to 8%).
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.
MCL: The most common adverse reactions (≥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 (≥5%) were pneumonia (7%), abdominal pain (5%), atrial fibrillation (5%), 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. Fatal and serious cases of renal failure have occurred. Increases in creatinine 1.5 to 3 times the upper limit of normal occurred in 9% of patients.
CLL: The most common adverse reactions (≥20%) in the clinical trials were thrombocytopenia (56%), neutropenia (51%), diarrhea (51%), anemia (37%), fatigue (28%), musculoskeletal pain (28%), upper respiratory tract infection (28%), rash (26%), nausea (25%), and pyrexia (24%). Approximately 5% of patients receiving IMBRUVICA® discontinued treatment due to adverse events. These included infections, subdural hematomas, and diarrhea. Adverse events leading to dose reduction occurred in approximately 6% 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.
