CAMBRIDGE, England - Tuesday, June 7th 2016 [ME NewsWire]
Data show objective response rate (ORR) of 31% in all evaluable patients and 46% in patients with PD-L1-high-expressing tumours1
PD-L1 expression correlates with response to durvalumab monotherapy per Ventana SP263 assay1
Results follow U.S. FDA’s recent Breakthrough Therapy Designation for durvalumab in patients with PD-L1 positive inoperable or metastatic urothelial bladder cancer2
(BUSINESS WIRE)-- AstraZeneca and its global biologics research and development arm, MedImmune, today announced efficacy and safety data for durvalumab, a selective programmed-death ligand-1 (PD-L1) antibody, in patients with advanced urothelial bladder cancer (UBC).1
Preliminary results of the Phase I/II trial, presented at the American Society of Clinical Oncology (ASCO) Annual Meeting, showed an objective response rate (ORR) of 31% in all evaluable patients (95% confidence interval (CI): 18%-47%) and 46% (95% CI: 28%-66%) in patients with PD-L1-high-expressing* tumours.1 Disease control rate (DCR), defined as confirmed complete or partial response or stable disease for 12 or more weeks, was 48% (95% CI: 32%-64%) in all evaluable patients, and 57% (95% CI: 37%-76%) in patients with PD-L1-high-expressing tumours.1 Median duration of response had not yet been reached.1
David Berman, Senior Vice President, Head of Oncology Innovative Medicines at MedImmune, said: “The efficacy data for durvalumab monotherapy in second-line bladder cancer are very encouraging, and confirm confidence in our diagnostic assay where the magnitude of response to durvalumab is clearly linked to PD-L1 expression. We look forward to continued exploration of durvalumab’s potential in our first-line bladder cancer trial, DANUBE, both as monotherapy and in combination with tremelimumab.”
Durvalumab 10mg/kg was administered every two weeks intravenously for up to 12 months, and demonstrated a manageable safety profile among all patients (n=61).1 The most common adverse events reported in 5% or more of patients were all grade 1 or 2: fatigue (13%), diarrhoea (10%), decreased appetite (8%), arthralgia (7%), asthenia (7%), nausea (7%) and pyrexia (7%).1 Three patients experienced treatment-related Grade 3 adverse events (1 acute kidney injury, 1 infusion-related reaction and 1 tumour flare).1
Dr. Christophe Massard, Head of Early Clinical Trials at the Institut Gustave Roussy, Villejuif, France, said: “These positive preliminary data continue to support durvalumab’s clinical efficacy and safety profile for the treatment of bladder cancer, and confirm durvalumab as a potential breakthrough therapy for a patient population with enormous unmet need.”
*PD-L1-high expression is defined as 25% or more PD-L1 staining in tumour cells (TCs) or immune cells (ICs) as assessed through use of the Ventana SP263 diagnostic assay1.
In 2016, durvalumab received Breakthrough Therapy Designation by the U.S. Food and Drug Administration as a potential treatment for patients with PD-L1 positive inoperable or metastatic UBC.2 Durvalumab is also being studied as monotherapy or in combination with tremelimumab, in non-small cell lung (NSCLC), head and neck, bladder, gastric, pancreatic, hepatocellular carcinoma (HCC) and blood cancers, and is a pillar of AstraZeneca’s late-stage immuno-oncology programme comprising more than 7,000 patients in 19 clinical trials across tumour types.3,4

NOTES TO EDITORS
About Durvalumab
Durvalumab is an investigational human monoclonal antibody directed against programmed death ligand-1 (PD-L1).5 PD-L1 expression enables tumours to evade detection from the immune system through binding to PD-1 on cytotoxic T lymphocytes.5,6 Durvalumab blocks PD-L1 interaction with both PD-1 and CD80 on T cells, countering the tumour's immune- evading tactics.5 Durvalumab is being developed alongside other immunotherapies to activate the patient's immune system to attack the cancer. Durvalumab is being investigated in an extensive clinical trial programme, as monotherapy or in combination with tremelimumab, in NSCLC, bladder, head and neck, gastric, pancreatic, HCC and blood cancers.4 In 2015, durvalumab received Fast Track Designation for the treatment of patients with PD-L1–positive metastatic SCCHN,7 and in 2016, durvalumab was granted Breakthrough Designation by the U.S. Food and Drug Administration as a potential treatment in patients with PD-L1 positive inoperable or metastatic urothelial bladder cancer.2
AstraZeneca’s Approach to Immuno-Oncology (IO)
Immuno-Oncology (IO) is a therapeutic approach designed to stimulate the body’s immune system to destroy tumours.8,9,10 At AstraZeneca, and MedImmune, our biologics research and development arm, our IO portfolio is anchored by immunotherapies that have been designed to overcome anti-tumour immune suppression.5,11 We believe that IO-based therapies will offer the potential for life-changing anti-cancer treatments for the vast majority of patients.
We are pursuing a comprehensive clinical trial programme that includes durvalumab (PD-L1) monotherapy and durvalumab in combination with tremelimumab (CTLA-4) in multiple tumour types, stages of disease, and lines of therapy,3 using the PD-L1 biomarker as a decision-making tool to define the best potential treatment path for a patient. In addition, the ability to combine our IO portfolio with small targeted molecules from across our oncology pipeline, and with those of our partners, may provide new treatment options across a broad range of tumours.
About AstraZeneca in Oncology
AstraZeneca has a deep-rooted heritage in Oncology and offers a quickly growing portfolio of new medicines that has the potential to transform patients’ lives and the Company’s future. With at least 6 new medicines to be launched between 2014 and 2020, and a broad pipeline of small molecules and biologics in development, we are committed to advance New Oncology as one of AstraZeneca’s six Growth Platforms focused on lung, ovarian, breast and blood cancers. In addition to our core capabilities, we actively pursue innovative partnerships and investments that accelerate the delivery of our strategy as illustrated by our investment in Acerta Pharma in haematology.
By harnessing the power of four scientific platforms -- immuno-oncology, the genetic drivers of cancer and resistance, DNA damage repair and antibody drug conjugates -- and by championing the development of personalised combinations, AstraZeneca has the vision to redefine cancer treatment and one day eliminate cancer as a cause of death.
