Durvalumab ATLANTIC trial supports clinical activity and AstraZeneca’s overall immuno-oncology strategy

Durvalumab demonstrated clinical activity and durable responses in 3^rd-line or later stage NSCLC patients; full data to be presented at a scientific congress in 2016

Durvalumab monotherapy and combination trials on track in multiple cancers, including 1st-line therapy for NSCLC, head & neck and bladder cancers

18 December 2015

AstraZeneca today provided an update on preliminary findings from the ATLANTIC trial of durvalumab as 3^rd-line or later stage therapy in patients with locally advanced or metastatic programmed death ligand-1 (PD-L1) positive non-small cell lung cancer (NSCLC) that lacks epidermal growth factor receptor (EGFR) or ALK alterations. An initial analysis supports durvalumab’s clinical activity, with durable responses and an established safety profile in these difficult-to-treat patients.

ATLANTIC investigated the efficacy and tolerability of durvalumab in patients who received at least two prior systemic treatment regimens including platinum-based chemotherapy, and who have limited options for further therapy. A full evaluation of the data is ongoing and the results will be presented at a scientific congress in 2016.

Sean Bohen, Executive Vice President, Global Medicines Development and Chief Medical Officer at AstraZeneca, said: “As we have seen in other studies, durvalumab has demonstrated expected clinical activity and durable response in these heavily pre-treated patients. As previously communicated, the treatment and regulatory landscape in lung cancer is evolving. We now believe it is unlikely that ATLANTIC can be used for regulatory submission as a monotherapy, but we will make that determination following a full analysis of the data. Durvalumab is a cornerstone of our immuno-oncology portfolio with a fast advancing development programme focused primarily on novel combinations.”

A comprehensive durvalumab registration programme is underway across multiple tumour types, stages of disease, and lines of therapy both as monotherapy and in combination. This forms part of AstraZeneca’s late-stage immuno-oncology programme and includes more than 9,000 patients in 16 clinical trials in lung, bladder, head & neck, and other cancers, summarised below.

NOTES TO EDITORS

About durvalumab (MEDI4736)

Durvalumab is an investigational human monoclonal antibody directed against PD-L1. Signals from PD-L1 help tumours avoid detection by the immune system. Durvalumab blocks these signals, countering the tumour's immune-evading tactics. Durvalumab is being developed, alongside other immunotherapies, to empower the patient's immune system and attack the cancer. Durvalumab is being investigated in an extensive clinical trial programme, as monotherapy or in combination with tremelimumab, in NSCLC, head and neck, gastric, pancreatic, bladder and blood cancers.

About the ATLANTIC trial

ATLANTIC is a Phase II, non-comparative, open-label, multi-centre, international trial of durvalumab in patients with locally advanced or metastatic NSCLC (Stage IIIB-IV) who have received at least two prior systemic treatment regimens including one platinum-based chemotherapy regimen.

About AstraZeneca in Oncology

Oncology is a therapy area in which AstraZeneca has deep-rooted heritage. It will be potentially transformational for the company’s future, becoming the sixth growth platform. Our vision is to help patients by redefining the cancer treatment paradigm and one day eliminate cancer as a cause of death. By 2020, we are aiming to bring six new cancer medicines to patients.

Our broad pipeline of next-generation medicines is focused on four main disease areas – lung, ovarian, breast and haematological cancers. These are being targeted through four key platforms – immuno-oncology, the genetic drivers of cancer and resistance, DNA damage repair and antibody drug conjugates.

About AstraZeneca
