The approval by the US Food and Drug Administration (FDA) was based on results from the OlympiA Phase III trial presented during the 2021 American Society of Clinical Oncology (ASCO) (Free ASCO Whitepaper) Annual Meeting and published in The New England Journal of Medicine.1

In the trial, Lynparza demonstrated a statistically significant and clinically meaningful improvement in invasive disease-free survival (iDFS), reducing the risk of invasive breast cancer recurrences, second cancers or death, by 42% versus placebo (based on a hazard ratio [HR] of 0.58; 95% confidence interval [CI] 0.46-0.74; p<0.0001).

New updated results from the OlympiA trial also showed Lynparza demonstrated a statistically significant and clinically meaningful improvement in the key secondary endpoint of overall survival (OS), reducing the risk of death by 32% versus placebo (based on a HR of 0.68; 95% CI 0.50-0.91; p=0.0091). The safety and tolerability profile of Lynparza in this trial was in line with that observed in prior clinical trials. The OS data will be presented at an upcoming European Society for Medical Oncology virtual plenary on 16 March 2022.

Breast cancer is the most diagnosed cancer worldwide with an estimated 2.3 million patients diagnosed in 2020.2 Almost 91% of all breast cancer patients in the US are diagnosed at an early stage of disease and BRCA mutations are found in approximately 5-10% of patients.3,4

Professor Andrew Tutt, Global Chair of the OlympiA Phase III trial and Professor of Oncology at The Institute of Cancer Research, London and King’s College London, said: "Today’s approval of olaparib is great news for patients with a specific inherited form of breast cancer. Most breast cancers are identified in the early stages and many patients will do very well, but for those with higher risk disease at diagnosis, the risk of cancer returning can be unacceptably high and new treatment options are needed. OlympiA has shown that identifying a BRCA1/2 mutation in women with high risk disease opens the additional option of eligibility for olaparib treatment, which reduces the risk of recurrence and improves survival for these breast cancer patients."

Dave Fredrickson, Executive Vice President, Oncology Business Unit, AstraZeneca, said: "This important approval gives early-stage breast cancer patients in the US with a germline BRCA mutation a new targeted therapy option in the adjuvant setting starting today. Lynparza reduces the risk of disease recurrence in these high-risk patients and now new data confirm it also significantly extends patients’ lives versus placebo. These data underline the importance of germline BRCA testing as soon as possible after diagnosis to identify patients that may be eligible for Lynparza."

Roy Baynes, Senior Vice President and Head of Global Clinical Development, Chief Medical Officer, MSD Research Laboratories, said: "For patients with germline BRCA-mutated, HER2-negative high-risk early breast cancer, who often present with more aggressive disease, today’s approval is an important step forward. Compared to placebo, Lynparza as adjuvant treatment offers these patients the potential to live longer without their cancer recurring. We thank the patients, caregivers and healthcare providers for their participation in the OlympiA trial."

Lynparza is now indicated for the adjuvant treatment of adult patients with deleterious or suspected deleterious gBRCAm HER2-negative high-risk early breast cancer who have been treated with neoadjuvant or adjuvant chemotherapy. Patients are to be selected for treatment based on an FDA-approved companion diagnostic test for Lynparza.

Lynparza is approved in the US, EU, Japan and several other countries for the treatment of patients with gBRCAm, HER2-negative, metastatic breast cancer previously treated with chemotherapy based on results from the OlympiAD Phase III trial. In the EU, this indication also includes patients with locally advanced breast cancer.

Notes

Financial considerations

Following this approval for Lynparza in the US, AstraZeneca will receive a regulatory milestone payment from MSD of $175m, anticipated to be booked as Collaboration Revenue by the Company during the first quarter of 2022.

Early breast cancer

Early breast cancer is defined as cancer confined to the breast with or without regional lymph node involvement, and the absence of distant metastatic disease.5 In the US, the 5-year survival rate is 99% for localised breast cancer (only found in the breast area) and 86% for regional breast cancer (cancer that has spread outside the breast to nearby structures or lymph nodes).3

Despite advances in the treatment of early breast cancer, up to 30% of patients with high-risk clinical and/or pathologic features recur within the first few years6, and patients with gBRCA mutations are more likely to be diagnosed at a younger age than those without these mutations.7

Breast cancer is one of the most biologically diverse tumour types with various factors fuelling its development and progression.8 The discovery of biomarkers in the development of breast cancer has greatly impacted scientific understanding of the disease.9

OlympiA

OlympiA is a Phase III, double-blind, parallel group, placebo-controlled, multicentre trial testing the efficacy and safety of Lynparza tablets versus placebo as adjuvant treatment in patients with gBRCAm high-risk HER2-negative early breast cancer, who have completed definitive local treatment and neoadjuvant or adjuvant chemotherapy.10

The primary endpoint of the trial is iDFS defined as time from randomisation to date of first locoregional or distant recurrence or new cancer or death from any cause.11

The OlympiA Phase III trial is led by the Breast International Group in partnership with the Frontier Science & Technology Research Foundation, NRG Oncology, the US National Cancer Institute, AstraZeneca and MSD. The trial is sponsored by NRG Oncology in the US and by AstraZeneca outside the US.12

BRCA

BRCA1 and BRCA2 are human genes that produce proteins responsible for repairing damaged DNA and play an important role maintaining the genetic stability of cells.11

When either of these genes is mutated or altered such that its protein product either is not made or does not function correctly, DNA damage may not be repaired properly, and cells become unstable. As a result, cells are more likely to develop additional genetic alterations that can lead to cancer and confer sensitivity to PARP inhibitors including Lynparza.11-14

Lynparza

Lynparza (olaparib) 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 (HRR), such as those with mutations in BRCA1 and/or BRCA2, or those where deficiency is induced by other agents (such as new hormonal agents – NHAs).

Inhibition of PARP proteins 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 currently approved in a number of countries across PARP-dependent tumour types with defects and dependencies in the DDR pathway including maintenance treatment of platinum-sensitive relapsed ovarian cancer and as both monotherapy and in combination with bevacizumab for the 1st-line maintenance treatment of BRCA-mutated (BRCAm) and homologous recombination repair deficient (HRD)-positive advanced ovarian cancer, respectively; for germline BRCAm, HER2-negative metastatic breast cancer (in the EU this includes locally advanced breast cancer); for germline BRCAm metastatic pancreatic cancer; and HRR gene-mutated metastatic castration-resistant prostate cancer (BRCAm only in the EU and Japan).

Lynparza, which is being jointly developed and commercialised by AstraZeneca and MSD, is the foundation of AstraZeneca’s industry-leading portfolio of potential new medicines targeting DDR mechanisms in cancer cells.

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 Koselugo (selumetinib), a mitogen-activated protein kinase (MEK) inhibitor, for multiple cancer types.

Working together, the companies will develop Lynparza and Koselugo in combination with other potential new medicines and as monotherapies. The companies will develop Lynparza and Koselugo in combination with their respective PD-L1 and PD-1 medicines independently.

AstraZeneca in breast cancer

Driven by a growing understanding of breast cancer biology, AstraZeneca is starting to challenge, and redefine, the current clinical paradigm for how breast cancer is classified and treated to deliver even more effective treatments to patients in need – with the bold ambition to one day eliminate breast cancer as a cause of death.

AstraZeneca has a comprehensive portfolio of approved and promising compounds in development that leverage different mechanisms of action to address the biologically diverse breast cancer tumour environment.

AstraZeneca aims to continue to transform outcomes for HR-positive breast cancer with foundational medicines Faslodex and Zoladex and the next-generation oral selective oestrogen receptor degrader (SERD) and potential new medicine camizestrant.

The PARP inhibitor, Lynparza, is an approved targeted treatment option for early and metastatic breast cancer patients with an inherited BRCA mutation. AstraZeneca with MSD continue to research Lynparza in breast cancer patients with an inherited BRCA mutation.

Building on the first approval of Enhertu, a HER2-directed antibody drug conjugate (ADC), in previously treated HER2-positive metastatic breast cancer, AstraZeneca and Daiichi Sankyo are exploring its potential in earlier lines of treatment and in new breast cancer settings.

To bring much needed treatment options to patients with triple-negative breast cancer, an aggressive form of breast cancer, AstraZeneca is testing immunotherapy Imfinzi in combination with other oncology medicines, including Lynparza and Enhertu, evaluating the potential of AKT kinase inhibitor, capivasertib, in combination with chemotherapy, and collaborating with Daiichi Sankyo to explore the potential of TROP2-directed ADC, datopotamab deruxtecan.

AstraZeneca in oncology

AstraZeneca is leading a revolution in oncology with the ambition to provide cures for cancer in every form, following the science to understand cancer and all its complexities to discover, develop and deliver life-changing medicines to patients.

The Company’s focus is on some of the most challenging cancers. It is through persistent innovation that AstraZeneca has built one of the most diverse portfolios and pipelines in the industry, with the potential to catalyse changes in the practice of medicine and transform the patient experience.

AstraZeneca has the vision to redefine cancer care and, one day, eliminate cancer as a cause of death.

Erasca Announces Clinical Trial Collaboration and Supply Agreement with Eli Lilly and Company to Evaluate ERAS-007 and Cetuximab Combination

On March 10, 2022 Erasca, Inc. (Nasdaq: ERAS), a clinical-stage precision oncology company singularly focused on discovering, developing, and commercializing therapies for patients with RAS/MAPK pathway-driven cancers, reported that it has entered into a clinical trial collaboration and supply agreement with Eli Lilly and Company for Lilly’s anti-EGFR antibody cetuximab (ERBITUX) (Press release, Erasca, MAR 10, 2022, View Source [SID1234639380]).

This agreement will support the ongoing Phase 1b/2 HERKULES-3 trial, a clinical proof-of-concept study evaluating ERAS-007, an oral ERK1/2 inhibitor, in various combinations, including with the BRAF inhibitor encorafenib (BRAFTOVI) and cetuximab for the treatment of patients with BRAF V600E-mutant metastatic colorectal cancer (mCRC). Erasca will sponsor the study, and Lilly will supply cetuximab at no cost. The two companies will form a joint committee to review the clinical trial results.

"We are grateful to Lilly for their collaboration as we explore the therapeutic potential of adding ERAS-007, our intermittently-dosed ERK1/2 inhibitor, to the current standard of care regimen for this patient population," said Jonathan E. Lim, M.D., Erasca’s chairman, CEO, and co-founder. "We expect the long-term benefits seen with current standard of care may be limited due to resistance mechanisms, particularly through MAPK reactivation. ERAS-007 inhibits the terminal node of the MAPK pathway and, based on preclinical models, offers more robust inhibition of MAPK reactivation over MEK and other ERK inhibitors. Additionally, ERAS-007’s pharmacokinetic and tolerability profile positions it well for combinations."

There are approximately 180,000 people, representing approximately 10% of all patients with CRC globally, who have BRAF V600E mutations. The combination of encorafenib plus cetuximab significantly improved overall survival in patients with mCRC with a BRAF V600E mutation compared to the control arm. Those clinical results also showed that 20% of patients experience an objective response and half of these responses last more than four months. Therefore, emergence of resistance is a major therapeutic barrier to long-term clinical benefit. Erasca is exploring whether ERK inhibition with ERAS-007 in combination with encorafenib plus cetuximab can reduce the emergence of resistance and further improve treatment benefit for patients with BRAF V600E CRC.

About ERAS-007
ERAS-007 is a potential best-in-class ERK1/2 inhibitor being investigated alone or in combination with different inhibitors targeting upstream nodes of the MAPK pathway as part of our MAPKlamp strategy. The extracellular signal-regulated kinases (ERK), ERK1 and ERK2, belong to a family of serine-threonine kinases that regulate cellular signaling and comprise the terminal node of the RAS/MAPK pathway. ERAS-007 is being investigated across a series of four HERKULES clinical trials that span multiple tumor types and include both monotherapy and combinations with approved and investigational agents, such as RTK, SHP2, RAS, RAF, and/or cell cycle inhibitors. HERKULES-1 is a Phase 1b/2 clinical trial for ERAS-007 as a single agent and in combination with the SHP2 inhibitor ERAS-601 in advanced solid tumors. HERKULES-2 is a Phase 1b/2 clinical trial for ERAS-007 in combination with various agents in patients with non-small cell lung cancer. HERKULES-3 is a Phase 1b/2 clinical trial for ERAS-007 in combination with various agents in patients with gastrointestinal cancers. HERKULES-4 is a Phase 1b/2 clinical trial for ERAS-007 in combination with various agents in patients with hematologic malignancies.
