AstraZeneca : Lynparza improved the time women lived without disease progression to 22 months in the broad population and to 37 months in HRD-positive patients as 1st-line maintenance treatment with bevacizumab for newly-diagnosed advanced ovarian cancer

Overall Grade 3 or above adverse events (AEs) were 57% for Lynparza added to bevacizumab and 51% for bevacizumab alone. The most common AEs ≥20% were nausea (53%), fatigue (53%), hypertension (46%), anaemia (41%), lymphopenia (24%), vomiting (22%) and arthralgia (22%). Grade 3 or above AEs were hypertension (19%), anaemia (17%), lymphopenia (7%), neutropenia (6%), fatigue (5%), nausea (2%), diarrhoea (2%), leukopenia (2%) vomiting (1%) and abdominal pain (1%). AEs led to dose interruption in 54% of patients on Lynparza while 20% of patients discontinued treatment.

Lynparza, which is being jointly developed and commercialised by AstraZeneca and MSD, is approved for the treatment of advanced ovarian cancer and metastatic breast cancer and has been used to treat over 25,000 patients worldwide. It is the only PARP inhibitor with positive Phase III trials in four different cancer types (ovarian, breast, pancreatic and prostate).

About PAOLA-1

PAOLA-1 is a double-blind Phase III trial testing the efficacy and safety of Lynparza added to SoC bevacizumab vs. bevacizumab alone, as a 1st-line maintenance treatment for newly-diagnosed advanced FIGO Stage III-IV high grade serous or endometroid ovarian, fallopian tube, or peritoneal cancer patients who had a complete or partial response to 1st-line treatment with platinum-based chemotherapy and bevacizumab.

PAOLA-1 is an ENGOT (European Network of Gynaecological Oncological Trial groups) trial, sponsored by ARCAGY Research (Association de Recherche sur les CAncers dont GYnécologiques) on behalf of GINECO (Groupe d'Investigateurs National des Etudes des Cancers Ovariens et du sein). ARCAGY-GINECO is an academic group specialising in clinical and translational research in patients' cancers and a member of the GCIG (Gynecologic Cancer InterGroup).

About ovarian cancer

Ovarian cancer is the eighth most common cause of death from cancer in women worldwide. In 2018, there were nearly 300,000 new cases diagnosed and around 185,000 deaths.¹ Most women are diagnosed with advanced (Stage III or IV) ovarian cancer and have a five-year survival rate of approximately 30%.² For newly-diagnosed advanced ovarian cancer, the primary aim of treatment is to delay progression of the disease for as long as possible and maintain the patient's quality of life with the intent of achieving complete remission or cure.^3,4,5,6

About homologous recombination deficiency

Homologous recombination deficiencies (HRDs) encompass a wide range of genetic abnormalities, including BRCA mutations, that can be detected using tests. As the BRCA gene drives DNA repair via homologous recombination, mutation of this gene leads to HR deficiency thereby interfering with normal cell DNA repair mechanisms. BRCA mutations are just one of many HRDs which are found in up to half of all newly diagnosed advanced ovarian cancer patients and confer sensitivity to PARP inhibitors including Lynparza.

About Lynparza

Lynparza is a first-in-class PARP inhibitor and the first targeted treatment to block DNA damage response (DDR) in cells/tumours harbouring a deficiency in homologous recombination repair, such as mutations in BRCA1 and/or BRCA2. Inhibition of PARP with Lynparza leads to the trapping of PARP bound to DNA single-strand breaks, stalling of replication forks, their collapse and the generation of DNA double-strand breaks and cancer cell death. Lynparza is being tested in a range of PARP-dependent tumour types with defects and dependencies in the DDR pathway.

Lynparza is currently approved in 64 countries, including those in the EU, for the maintenance treatment of platinum-sensitive relapsed ovarian cancer, regardless of BRCA status. It is approved in the US, the EU, Japan and several other countries as 1st-line maintenance treatment of BRCA-mutated advanced ovarian cancer following response to platinum-based chemotherapy. It is also approved in 43 countries, including the US and Japan, for germline BRCA-mutated, HER2-negative, metastatic breast cancer, previously treated with chemotherapy; in the EU, this includes locally-advanced breast cancer. Regulatory reviews are underway in other jurisdictions for ovarian, breast and pancreatic cancers.

Lynparza, which is being jointly developed and commercialised by AstraZeneca and MSD, is approved for the treatment of advanced ovarian cancer and metastatic breast cancer and has been used to treat over 25,000 patients worldwide. Lynparza has the broadest and most advanced clinical-trial development programme of any PARP inhibitor, and AstraZeneca and MSD are working together to understand how it may affect multiple PARP-dependent tumours as a monotherapy and in combination across multiple cancer types. Lynparza is the foundation of AstraZeneca's industry-leading portfolio of potential new medicines targeting DDR mechanisms in cancer cells.

About GINECO

GINECO (Groupe d'Investigateurs National des Etudes des Cancers Ovariens et du sein) is the French Cooperative Group in Oncology labelled by INCA (Institut National du Cancer, or French NCI) developing and conducting gynaecological and metastatic breast cancer clinical trials at the national and international level. Founded in 1993, the GINECO group is a member of international consortia such as ENGOT and GCIG.

About ENGOT

ENGOT (European Network for Gynaecological Oncological Trial groups) is a research network of the European Society of Gynaecological Oncology (ESGO). Founded in 2007, ENGOT includes 21 cooperative groups from 25 European countries.

About GCIG

The GCIG (Gynecological Cancer InterGroup) aims to promote and facilitate high quality clinical trials in order to improve outcomes for women with gynaecological cancer. Founded in 1998, GCIG includes 23 cooperative groups from 28 countries worldwide.

About the AstraZeneca and MSD strategic oncology collaboration

In July 2017, AstraZeneca and Merck & Co., Inc., Kenilworth, NJ, US, known as MSD outside the US and Canada, announced a global strategic oncology collaboration to co-develop and co-commercialise Lynparza, the world's first PARP inhibitor, and potential new medicine selumetinib, a MEK inhibitor, for multiple cancer types. Working together, the companies will develop Lynparza and selumetinib in combination with other potential new medicines and as monotherapies. Independently, the companies will develop Lynparza and selumetinib in combination with their respective PD-L1 and PD-1 medicines.

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 six new medicines to be launched between 2014 and 2020, and a broad pipeline of small molecules and biologics in development, the Company is committed to advance oncology as a key growth driver for AstraZeneca focused on lung, ovarian, breast and blood cancers. In addition to AstraZeneca's main capabilities, the Company is actively pursuing innovative partnerships and investment that accelerate the delivery of our strategy, as illustrated by the investment in Acerta Pharma in haematology.

By harnessing the power of four scientific platforms - Immuno-Oncology, Tumour Drivers and Resistance, DNA Damage Response 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.
