Presentations highlight new Immuno-Oncology and DNA Damage Response targets, expanding beyond checkpoint and PARP inhibition

AstraZeneca will share pioneering research and development across its successful Oncology portfolio and extensive next-generation pipeline at the American Association for Cancer Research (AACR) Annual Meeting in Atlanta, USA, 29 March to 3 April 2019.

The new research will showcase AstraZeneca’s potent and selective DNA-dependent protein kinase (DNA-PK) inhibitor, taking the DNA Damage Response (DDR) pipeline beyond PARP inhibition. Additional highlights include new insights from the MYSTIC and TATTON trials for Imfinzi (durvalumab) and Tagrisso (osimertinib) in predicting response and addressing treatment resistance in lung cancer.

In total, data from 84 presentations will illustrate the progress of AstraZeneca’s Oncology pipeline, with 28 abstracts reporting new Immuno-Oncology (IO) data, 33 focused on complementary biological pathways exploring the DDR mechanism, and 20 on tumour drivers and resistance mechanisms.

Jose´ Baselga, Executive Vice President, Research & Development, Oncology, said: “AstraZeneca is continuing to strengthen its portfolio of innovative cancer medicines by exploring new indications and developing a pioneering next-generation pipeline. We will be sharing some of our latest research at the 2019 AACR Annual Meeting, including 28 new molecular entities and six combinations, highlighting an exciting new phase of scientific discovery from our Oncology R&D.”


IO pipeline explores new pathways to enhance immune response

Key data from AstraZeneca’s early-stage clinical and preclinical IO pipeline include potential new medicines targeting multiple pathways, providing insight into novel mechanisms to boost current immune response and modify the tumour microenvironment both alone and in combination with checkpoint inhibition.

Presentations will highlight AstraZeneca’s growing portfolio in small molecules and antisense oligonucleotides (ASOs) targeting immunosuppressive mechanisms in cancer, and the Company’s exploration of the adenosine pathway, which is increasingly recognised as critical to tumour suppression and represents a new frontier within IO.

> Phase I and preclinical data demonstrating AZD4635, a small molecule A2AR antagonist, prevents adenosine-mediated immunosuppression. Early clinical activity has been observed with AZD4635 monotherapy or in combination with Imfinzi in patients with metastatic castration-resistant prostate cancer (Abstracts #LB-192/10, #CT026/21)

> Preclinical research on the activity of ASO AZD8701 (ION-AZ7), showing that inhibiting FOXP3 may limit immunosuppressive functions and induce tumour regression (Abstract #2713)

> Preclinical pharmacodynamic and mechanistic data illustrating how danvatirsen (AZD9150), a STAT3 ASO reverses immunosuppression to produce significant anti-tumour effects, both as monotherapy and in combination with anti-PDL1 (Abstract #3215/25)

> Preclinical data for MEDI5083, a novel fusion protein which activates the CD40 pathway, indicating robust immune activation and anti-tumour activity (Abstract #1534/3)

> Preclinical data for MEDI1191, a novel IL12-based treatment designed for injection directly into tumours, showing potential to drive anti-tumour response for patients with solid tumours both as monotherapy and in combination with anti-PDL1 (Abstract #5017/11)


Next wave of DDR targets

New research will showcase AstraZeneca’s DDR pipeline beyond PARP inhibition, including on the discovery and first structural disclosure of AZD7648, a potent and selective DNA-PK inhibitor (Abstract #DDT01-02). DNA-PK is critical in repairing DNA double strand breaks through the non-homologous end joining (NHEJ) pathway and has also been linked to the replication stress response (RSR), a type of DDR.

Additional new data will be shared on reversing PARP inhibitor resistance by targeting alternative DDR dependencies, like the RSR (Abstract #932).

Predicting response and addressing treatment resistance in lung cancer: new insights from MYSTIC and TATTON trials for Imfinzi and Tagrisso

Exploratory analyses of blood and tissue tumour mutational burden (TMB) from the Phase III MYSTIC trial assess TMB as a potential biomarker of survival in 1st-line use of Imfinzi with or without tremelimumab vs. chemotherapy in metastatic non-small cell lung cancer (NSCLC) (Abstract #CT074). The trial did not meet the primary endpoints, but Imfinzi monotherapy demonstrated clinical activity in the primary analysis. The MYSTIC trial provides the most comprehensive data set to date evaluating blood TMB and is the only Phase III randomised, controlled trial to demonstrate an association between high TMB and overall survival benefit with immunotherapy treatment. This new analysis will further evaluate the use of TMB as a potential biomarker predictive of survival benefit with IO treatment.

In addition, several abstracts will be presented from the TATTON Phase Ib trial testing the combination of Tagrisso with potential new medicines savolitinib or selumetinib in NSCLC patients who have progressed on prior epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) treatment (Abstracts #CT032, #CT033, #CT034). The TATTON trial supports SAVANNAH, an ongoing Phase II clinical trial exploring the combination of Tagrisso and savolitinib to overcome MET-driven EGFR-TKI resistance following treatment with Tagrisso in EGFR-mutated (EGFRm) NSCLC. Characterisation of detection methods for identifying MET-driven EGFR-TKI resistance will be presented (Abstract #4897/20). TATTON will also inform the trial design of ORCHARD, a Phase II platform trial exploring potential new treatment options to address resistance mechanisms in patients with EGFRm NSCLC who have experienced disease progression following 1st-line treatment with Tagrisso.
