Highlights will include new data demonstrating the strength and versatility of AstraZeneca’s industry-leading line of DNA damage response (DDR) medicines in multiple types of cancer. New data will highlight the continued momentum behind AstraZeneca’s numerous immuno-oncology (IO) programmes, and showcase small-molecule developments including Tagrisso (osimertinib) in leptomeningeal (brain) disease and the highly-selective Bruton’s tyrosine kinase (BTK) inhibitor, acalabrutinib, in chronic lymphocytic leukaemia (CLL).

Sean Bohen, Executive Vice President, Global Medicines Development and Chief Medical Officer at AstraZeneca, said: "Oncology is a strategic priority for AstraZeneca because of the potential of our broad pipeline to offer transformational therapies in cancer care. At ASCO (Free ASCO Whitepaper), we will update on our next-generation portfolio focusing on DNA damage response as a breakthrough paradigm in cancer treatment, including new long-term overall survival data for Lynparza. Our increased commitment to DDR therapies complements developments in our exciting immuno-oncology pipeline, from which we are expecting clinical results over the coming year."

DDR: A promising scientific platform, a leading position for AstraZeneca

DDR is a term describing the network of cellular pathways that minimise the daily impact of DNA damage. Currently, many cancers are known to have defects in DDR pathways, which makes them dependent on and therefore, highly sensitive to inhibition of the remaining DDR pathways. Targeting DDR deficiencies to preferentially kill cancer cells, while minimising the impact on normal cells, has potential for more selective, better tolerated therapies to improve survival in multiple cancers.

AstraZeneca is developing a comprehensive pipeline of compounds that target molecular pathways across the DDR system. These include the PARP inhibitor Lynparza (olaparib); Wee1 inhibitor AZD1775, ATM inhibitor AZD0156; ATR inhibitor AZD6738, and Aurora B Kinase inhibitor AZD2811. These compounds act on different cell-cycle points to prevent tumour cells from reproducing.

At the ASCO (Free ASCO Whitepaper) congress, DDR presentations will highlight:

The potential for maintenance of DDR therapies as shown by Lynparza overall survival data from Study 19 in ovarian cancer (Abstract # 5501). This abstract has been selected as a "Best of ASCO (Free ASCO Whitepaper)" abstract.
Opportunities for combination approaches with DDR and immuno-oncology therapies as shown in a Phase I study of the PD-L1 inhibitor, durvalumab, in combination with Lynparza or a VEGFR inhibitor, cediranib, in women’s cancers (Abstract # 3015)
The importance of selecting patients with a DDR pathway defect using the right diagnostic tool (abstract #4041)
The potential of DDR therapies against multiple biological DDR targets in different tumour types, with studies of the highly-selective WEE1 inhibitor, AZD1775, in advanced high-grade serous ovarian cancer (Abstract # TPS5610), squamous cell carcinoma of the head and neck (SCCHN) (Abstract # TPS6106), advanced solid tumours (Abstract # TPS2608) and glioblastoma (GBM) (Abstract # 2008)
Immuno-Oncology: Robust development momentum on track for read-outs in H1 2017

AstraZeneca is leading in a number of first-line studies with its IO strategy, where combined PD-L1 and CTLA-4 blockade – through the combination of durvalumab and tremelimumab – may address a significant unmet medical need for cancer patients who may not benefit from PD-1 pathway drugs in monotherapy.

Key updates include presentations covering pre-clinical data, late-stage trials and biomarker research:

Early study results of durvalumab monotherapy in urothelial bladder cancer from Phase Ib Study 1108 (Abstract # 4502)
Final results from a Phase III study of tremelimumab in mesothelioma (Abstract # 8502)
New study results on safety and clinical activity of durvalumab as first-line treatment in non-small cell lung cancer (NSCLC) (Abstract # 9029)
Ongoing investigation of the potential synergistic effects of durvalumab and the CTLA-4 inhibitor, tremelimumab, in bladder cancer (DANUBE trial – Abstract # TPS4574) and SCCHN (KESTREL trial – Abstract # TPS6101)
Enhanced understanding of PD-L1 biomarker expression in relation to primary versus metastatic tumours and sample age (Abstract # 3025)
Tagrisso in brain metastasis; acalabrutinib in CLL

AstraZeneca’s strong heritage in developing innovative targeted small molecules was underscored by the recent approval of Tagrisso as the first indicated treatment for EGFR T790M mutation-positive metastatic NSCLC in the US, EU and Japan. At ASCO (Free ASCO Whitepaper), new data will highlight the importance of Tagrisso activity in leptomeningeal disease through its ability to penetrate the blood-brain barrier. Further presentations will show the growing role of circulating tumour DNA (ctDNA) testing for diagnosis and treatment monitoring.

Key updates will also include presentation on the potential of our potent, highly-selective BTK inhibitor, acalabrutinib, in chronic lymphocytic leukaemia (CLL):

Data from the BLOOM study of Tagrisso in patients with leptomeningeal disease as a complication of EGFRm-metastatic NSCLC (Abstract # 9002)
Intensive plasma ctDNA profiling in experimental trials to identify markers of acquired drug resistance (Abstract # 11530)
Acalabrutinib – preliminary results from a first-line study as first-line therapy in CLL (Abstract # 7521) and in a Phase II study in combination with pembrolizumab in metastatic pancreatic cancer (Abstract # 4130)

The Edge Radiosurgery system, which will be installed in one of Apollo’s tertiary care centers, is a precise, non-invasive alternative to conventional surgery. With enhanced precision and speed, the Edge system offers state of the art radiosurgery and can treat a wide range of conditions across an ever increasing number of clinical indications. Varian’s flagship TrueBeam family of linear accelerators, to be installed at hospitals throughout the Apollo chain, incorporates numerous technical innovations that dynamically synchronize imaging, patient positioning, motion management, and treatment delivery during a radiotherapy or radiosurgery procedure.

As well as advanced treatment equipment, Apollo is ordering a full suite of Varian software tools including the Eclipse treatment planning system and ARIA oncology information management system, along with specific modules such as RapidPlan to enhance the speed and quality of treatment plans, and the InSightive Analytics real-time dashboard to maximize workflow in a clinic.

"We are pleased that Apollo has selected our technology-leading hardware and software to offer their cancer patients fast and precise treatments," says Ashok Kakkar, senior managing director of Varian India. "India is severely under-equipped when it comes to radiotherapy treatment machines and more than two million new cancer cases are detected each year in the country. Programs such as this help to make a big difference in the treatment of cancer patients in India."

Commenting on the collaboration, Dr. Preetha Reddy, executive vice chairperson of Apollo Hospitals Enterprise Limited said, "Healthcare has evolved by leaps and bounds in the past few years and technology has played a critical role in improving clinical outcomes for patients. Providing high quality healthcare on a par with global standards is our prime objective and we are glad to partner with Varian in this endeavor. Already enriched with highly skilled doctors, technicians and physicians, cutting edge technology will further enhance India’s positioning as a global healthcare destination."

Last year, Varian and Apollo announced a collaboration on the first radiotherapy educational co-operation of its kind between industry and a care provider in India. In this collaboration, Varian and Apollo will work together to bring greater access to training in modern radiotherapy by leveraging the existing Apollo Knowledge network that comprises several educational entities in the healthcare space in India. This collaboration with Apollo is a furtherance of Varian’s Access to Care program, which seeks to bridge the gap between the growing need for modern radiotherapy treatment machines in developing countries and the lack of trained personnel to operate them.

The poster (P191), entitled "Results of a Phase 1 study of GMI-1271, a novel E-selectin antagonist in combination with induction chemotherapy in relapse/refractory AML: a novel, well-tolerated regimen with a high remission rate," is scheduled for 5:15 p.m. CET on Friday, June 10.

The abstract is available here

About GMI-1271

GMI-1271 is designed to block E-selectin (an adhesion molecule on cells in the bone marrow) from binding with acute myeloid leukemia (AML) cells in ways that help the cancer cells evade the effects of chemotherapy treatment. Preclinical research points to the drug’s potential role in moving cancerous cells out of the protective environment of the bone marrow where they hide and escape the effects of chemotherapy. By blocking E-selectin, GMI-1271 also may protect normal blood-producing cells, and reduce the toxic side effects of chemotherapy such as low white blood cell counts that make some patients more prone to infections. GMI-1271 may also reduce mucositis (inflammation or lesions in the intestinal tract and mouth), which can be a side effect of chemotherapy. GlycoMimetics has announced encouraging initial top line data from the first two cohorts in its ongoing Phase 1/2 clinical study.

About Duvelisib
Duvelisib is an investigational dual inhibitor of phosphoinositide-3-kinase (PI3K)-delta and PI3K-gamma, two proteins that are known to help support the growth and survival of malignant B-cells. PI3K signaling may lead to the proliferation of malignant B-cells and is thought to play a role in the formation and maintenance of the supportive tumor microenvironment. 1-3AbbVie and Infinity Pharmaceuticals, Inc. are jointly researching and developing duvelisib in various cancer types.

Duvelisib is being evaluated in several studies, including a Phase 2 study in patients with refractory indolent non-Hodgkin lymphoma4, a Phase 3 study in combination with other agents in patients with previously treated follicular lymphoma5 and a Phase 3 study in patients with relapsed/refractory chronic lymphocytic leukemia6. Duvelisib is an investigational compound and its safety and efficacy have not been evaluated by the FDA or any other health authority.

About IPI-549
IPI-549 is an orally administered immuno-oncology development candidate that selectively inhibits PI3K-gamma. In preclinical studies, IPI-549 inhibits immune-suppressive macrophages within the tumor microenvironment, whereas other immunotherapies such as checkpoint modulators more directly target immune effector cell function. As such, IPI-549 may have the potential to treat a broad range of solid tumors and represents a potentially complementary approach to restoring anti-tumor immunity in combination with other immunotherapies such as checkpoint inhibitors.

These are investigational drugs being studied for indications that have not been approved by Regulatory Agencies. Safety and efficacy have not been established in unapproved indications.
