WILMINGTON, Del.--( BUSINESS WIRE )--Updated results from the OlympiA Phase III trial showed AstraZeneca and Merck & Co., Inc’s, known as MSD outside of the US and Canada, LYNPARZA ® (olaparib) demonstrated sustained, clinically meaningful improvements in overall survival (OS), invasive disease-free survival (IDFS) and distant disease-free survival (DDFS) at six years for patients with germline BRCA-mutated (gBRCAm) HER2-negative high-risk early breast cancer. These results were presented today at the San Antonio Breast Cancer Symposium 2024 (SABCS) (#GS1-09) and build on the positive primary results published in The New England Journal of Medicine . At a median follow-up of 6.1 years in eligible patients, who had completed local treatment and standard neoadjuvant or adjuvant chemotherapy, results showed LYNPARZA reduced the risk of death by 28% (hazard ratio [HR] 0.72; 95% confidence interval [CI] 0.56-0.93) versus placebo. In addition, 87.5% of patients treated with LYNPARZA remained alive versus 83.2% of those on placebo. LYNPARZA also demonstrated sustained and clinically meaningful improvements in the primary and secondary endpoints of IDFS and DDFS. LYNPARZA reduced the risk of invasive breast cancer recurrence, second cancers or death by 35% (HR 0.65; 95% CI; 0.53-0.78) and reduced the risk of distant disease recurrence or death by 35% (HR 0.65; 95% CI; 0.53-0.81) versus placebo. The benefit with LYNPARZA was consistent across all key subgroups, including patients with high-risk, hormone-receptor-positive disease. Judy E. Garber, Chief of the Division of Cancer Genetics and Prevention at Dana-Farber Cancer Institute and co-principal investigator of the trial said: “ These exciting long-term data from OlympiA confirm that adjuvant treatment with olaparib for one year continues to deliver clinically meaningful survival benefit for patients with germline BRCA-mutated high-risk HER2-negative early breast cancer even after six years, with benefit persisting in all subgroups and with toxicity and pregnancy data reassuring for this generally younger group. These data reinforce the importance of germline BRCA testing at the time of diagnosis, so we can identify all eligible patients who may benefit from treatment with olaparib as early as possible.” Susan Galbraith, Executive Vice President, Oncology R&D, AstraZeneca, said: “ Two years ago, LYNPARZA became the first and only PARP inhibitor to demonstrate a survival benefit in germline BRCA-mutated, HER2-negative and high-risk early-stage breast cancer. To see this benefit continue at six years of follow-up is tremendous for patients and reinforces how LYNPARZA is continuing to transform the treatment of BRCA-mutated early-stage breast cancer.” Eliav Barr, Senior Vice President, Head of Global Clinical Development and Chief Medical Officer, Merck Research Laboratories, said: “ The durable long-term efficacy seen in the OlympiA study reinforces LYNPARZA as an important treatment option for those living with this truly challenging, very aggressive form of the disease.” Summary of results LYNPARZA (n=921) Placebo (n=915) IDFS (primary endpoint) HR (95% CI) 0.65 (0.53, 0.78) IDFS rates at 6 years 79.6% 70.3% DDFS (secondary endpoint) HR (95% CI) 0.65 (0.53, 0.81) DDFS rates at 6 years 83.5% 75.7% OS (secondary endpoint) HR (95% CI) 0.72 (0.56, 0.93) OS rates at 6 years 87.5% 83.2% The safety and tolerability profile of LYNPARZA in this trial was in line with that observed in prior clinical trials and no new safety signals were identified with longer follow-up. No evidence of an increased risk of myelodysplastic syndrome or acute myeloid leukemia was observed compared to those on placebo. The OlympiA trial is coordinated by the Breast International Group (BIG) in partnership with NRG Oncology, the US National Cancer Institute (NCI), the Frontier Science & Technology Research Foundation (FSTRF), AstraZeneca and Merck & Co., Inc. 1 LYNPARZA is approved in the US, EU, Japan, and many other countries for the treatment of gBRCAm, HER2-negative high-risk early breast cancer. LYNPARZA is also approved in the US, EU, Japan, and many other countries for the treatment of patients with gBRCAm, HER2-negative metastatic breast cancer. In the EU, this indication also includes patients with locally advanced breast cancer. IMPORTANT SAFETY INFORMATION ABOUT LYNPARZA ® (olaparib) tablets CONTRAINDICATIONS There are no contraindications for LYNPARZA. WARNINGS AND PRECAUTIONS Myelodysplastic Syndrome/Acute Myeloid Leukemia (MDS/AML): Occurred in approximately 1.2% of patients with various BRCA m, g BRCA m, HRR gene-mutated or HRD-positive cancers who received LYNPARZA as a single agent or as part of a combination regimen, consistent with the approved indications, and the majority of events had a fatal outcome. The median duration of therapy in patients who developed MDS/AML was approximately 2 years (range: <6 months to >4 years). All of these patients had previous chemotherapy with platinum agents and/or other DNA-damaging agents, including radiotherapy. In SOLO-1, patients with newly diagnosed advanced BRCA m ovarian cancer, the incidence of MDS/AML was 1.9% (5/260) in patients who received LYNPARZA and 0.8% (1/130) in patients who received placebo based on an updated analysis. In PAOLA-1, of patients with newly diagnosed advanced ovarian cancer with HRD-positive status, the incidence of MDS/AML was 1.6% (4/255) in patients who received LYNPARZA and 2.3% (3/131) in the control arm. In SOLO-2, patients with BRCA m platinum-sensitive relapsed ovarian cancer, the incidence of MDS/AML was 8% (15/195) in patients who received LYNPARZA and 4% (4/99) in patients who received placebo. The duration of LYNPARZA treatment prior to the diagnosis of MDS/AML ranged from 0.6 years to 4.5 years. Do not start LYNPARZA until patients have recovered from hematological toxicity caused by previous chemotherapy (≤Grade 1). Monitor complete blood count for cytopenia at baseline and monthly thereafter for clinically significant changes during treatment. For prolonged hematological toxicities, interrupt LYNPARZA and monitor blood count weekly until recovery. If the levels have not recovered to Grade 1 or less after 4 weeks, refer the patient to a hematologist for further investigations, including bone marrow analysis and blood sample for cytogenetics. Discontinue LYNPARZA if MDS/AML is confirmed. Pneumonitis: Occurred in 0.8% of patients exposed to LYNPARZA monotherapy, and some cases were fatal. If patients present with new or worsening respiratory symptoms such as dyspnea, cough, and fever, or a radiological abnormality occurs, interrupt LYNPARZA treatment and initiate prompt investigation. Discontinue LYNPARZA if pneumonitis is confirmed and treat patient appropriately. Venous Thromboembolism (VTE): Including severe or fatal pulmonary embolism (PE) occurred in patients treated with LYNPARZA. In the combined data of two randomized, placebo-controlled clinical studies (PROfound and PROpel) in patients with metastatic castration-resistant prostate cancer (N=1180), VTE occurred in 8% of patients who received LYNPARZA, including pulmonary embolism in 6%. In the control arms, VTE occurred in 2.5%, including pulmonary embolism in 1.5%. Monitor patients for signs and symptoms of venous thrombosis and pulmonary embolism, and treat as medically appropriate, which may include long-term anticoagulation as clinically indicated. Embryo-Fetal Toxicity: Based on its mechanism of action and findings in animals, LYNPARZA can cause fetal harm. Verify pregnancy status in females of reproductive potential prior to initiating treatment. Females Advise females of reproductive potential of the potential risk to a fetus and to use effective contraception during treatment and for 6 months following the last dose. Males Advise male patients with female partners of reproductive potential or who are pregnant to use effective contraception during treatment and for 3 months following the last dose of LYNPARZA and to not donate sperm during this time.

Notes 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. 2 In the US, the 5-year survival rate is 99.6% for localized breast cancer (only found in the breast area) and 86.7% for regional breast cancer (cancer that has spread outside the breast to nearby structures or lymph nodes). 3 Despite advancements 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 years and patients with gBRCA mutations are more likely to be diagnosed at a younger age than those without these mutations. 4,5 Breast cancer is one of the most biologically diverse tumor types with various factors fueling its development and progression. 6 The discovery of biomarkers in the development of breast cancer has greatly impacted scientific understanding of the disease. 7 OlympiA OlympiA is a phase III, double-blind, parallel group, placebo-controlled, multicenter trial evaluating the efficacy and safety of LYNPARZA tablets versus placebo as a 12-month adjuvant treatment for adult patients with gBRCAm HER2-negative early breast cancer, who have completed neoadjuvant or adjuvant chemotherapy. 1 The primary endpoint of the trial is invasive disease-free survival defined as time from randomization to date of first loco-regional or distant recurrence or new cancer or death from any cause. Key secondary endpoints include distant disease-free survival and overall survival, which is defined as time from randomization until documented evidence of first distant recurrence of breast cancer or death without distant recurrence. 1 Breast International Group (BIG) BIG is an international not-for-profit organization for academic breast cancer research groups from around the world, based in Brussels, Belgium.

The NCI and AstraZeneca are collaborating under a Cooperative Research and Development Agreement between the parties. 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. 8 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. 8-11 LYNPARZA LYNPARZA ® (olaparib) is a first-in-class PARP inhibitor and the first targeted treatment to block DNA damage response (DDR) in cells/tumors harboring a deficiency in homologous recombination-related (HRR) genes, 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 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 may also help enhance immunogenicity and increase the impact of anti-tumor immune responses. LYNPARZA is currently approved in a number of countries across multiple tumor types, 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 gBRCAm metastatic pancreatic cancer; in combination with abiraterone for the treatment of metastatic castration-resistant prostate cancer (mCRPC) when chemotherapy is not clinically indicated (EU only) and for BRCAm mCRPC (US and Japan); as monotherapy for HRR gene-mutated mCRPC in patients who have progressed on prior NHA treatment (BRCAm only in the EU and Japan); and in combination with durvalumab following durvalumab plus chemotherapy as 1st-line treatment for advanced or recurrent endometrial cancer that is mismatch repair proficient (EU and Japan). In China, LYNPARZA is approved for the treatment of BRCA-mutated mCRPC as well as 1st-line maintenance treatment with bevacizumab for HRD-positive advanced ovarian cancer. LYNPARZA, which is being jointly developed and commercialized by AstraZeneca and Merck & Co., Inc., known as MSD outside the US and Canada, has been used to treat over 140,000 patients worldwide. LYNPARZA has a broad clinical trial development program, and AstraZeneca and Merck & Co., Inc., are working together to understand how it may affect multiple PARP-dependent tumors 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. The AstraZeneca and Merck & Co., Inc., 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-commercialize LYNPARZA, the world’s first PARP inhibitor, and selumetinib, a mitogen-activated protein kinase (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. The companies will develop LYNPARZA and selumetinib in combination with their respective PD-L1 and PD-1 medicines independently.

Exploratory long-term follow-up analysis of the phase III POLARIX study indicated a positive trend in overall survival in favour of Polivy in combination with R-CHP for people with first-line diffuse large B-cell lymphoma (DLBCL)1 Patients treated with Polivy in combination with R-CHP required fewer subsequent treatments, potentially reducing burdens on patients and healthcare systems1 These encouraging five-year results continue to highlight the potential of this Polivy combination to improve outcomes in first-line DLBCL, an area that previously had little advancement in nearly two decades 8 December 2024 - Roche (SIX: RO, ROG; OTCQX: RHHBY) announced today data from a five-year follow-up of the pivotal phase III POLARIX study evaluating Polivy® (polatuzumab vedotin) in combination with MabThera®/Rituxan® (rituximab), cyclophosphamide, doxorubicin and prednisone (R-CHP) in people with untreated diffuse large B-cell lymphoma (DLBCL). Data were presented in an oral session at the 66th American Society of Hematology (ASH) Annual Meeting and Exposition, 7-10 December 2024 in San Diego, US. This latest analysis conducted after a median follow-up of 60.9 months, includes descriptive data on primary and secondary endpoints, as well as safety results.1 “POLARIX was the first trial to elevate treatment standards for frontline diffuse large B-cell lymphoma in 20 years and we are additionally encouraged by the five-year follow-up results,” said Levi Garraway, MD, PhD, Roche’s Chief Medical Officer and Head of Global Product Development. “More than 38,000 people worldwide have been treated with Polivy in combination with R-CHP and these data continue to underscore its potential to improve outcomes for people diagnosed with this aggressive lymphoma.” Follow-up exploratory analysis after five-years indicated a positive trend in overall survival (OS) in the intent-to-treat (ITT) population in favour of Polivy in combination with R-CHP compared to MabThera/Rituxan plus cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP). Results showed a trend in reduction in the risk of death (HR 0.85; 95% CI: 0.63–1.15) for people with previously untreated DLBCL with the Polivy combination, an improvement on the three-year follow-up data (HR 0.94; 95% CI: 0.67–1.33). The five-year analysis of POLARIX indicates that the full difference in OS between treatment arms has yet to be observed and an additional two years of follow-up will continue.1 “Diffuse large B-cell lymphoma is a notoriously challenging cancer to treat, however, Polivy in combination with R-CHP has shown to be a critical advance for patients by helping to reduce relapse and disease progression,” said Gilles Salles, MD, PhD, Chief of Lymphoma Service, Division of Hematological Malignancies, Memorial Sloan Kettering Cancer Center, US. “The survival trend seen in this follow-up analysis reinforces the potential impact of frontline treatment with Polivy in combination with R-CHP and its role as a standard of care therapy.” In addition to the positive trend in OS, an observational analysis suggested nearly 25% fewer follow-up treatments such as radiation, systemic chemotherapy and CAR-T cell therapy were needed in patients receiving Polivy in combination with R-CHP compared to those treated with R-CHOP (38.3% vs 61.7%).1 Based on findings from a previous economic analysis which found that total healthcare costs increased with each additional line of treatment in relapsed or refractory DLBCL, a reduction in the number of subsequent therapies could potentially alleviate some of the burdens associated with relapse and disease progression.2 At five years of follow-up, benefits in progression-free survival and disease-free survival with Polivy in combination with R-CHP were maintained, consistent with the three-year follow-up data, reinforcing the potential of Polivy in combination with R-CHP to provide durable and lasting remissions. The latest follow-up data also showed a numerical reduction in death related to patients’ lymphoma in those treated with Polivy in combination with R-CHP compared to those treated with R-CHOP (9.0% vs 11.4%). The safety profile remains consistent with the known profiles of the individual study medicines with no new safety signals observed, reinforcing the positive benefit-risk profile of this Polivy combination.1 Results from an expanded cohort of 1,000 patients including global and Chinese patients demonstrated comparability to the global ITT population.1 Polivy in combination with R-CHP is currently approved for the treatment of first-line (1L) DLBCL in more than 90 countries worldwide including the US, countries throughout the EU, the UK, Japan, Canada and China. Roche continues to work with health authorities around the world to bring this treatment regimen to even more patients. Roche aims to offer various treatment options for DLBCL that meet the diverse needs of patients and healthcare systems. In an effort to elevate treatment standards even further, Roche is exploring Polivy in combination with other molecules including its bispecific antibodies. Studies include the phase III SUNMO trial evaluating the efficacy and safety of subcutaneously administered Lunsumio® (mosunetuzumab) in combination with intravenous (IV) Polivy versus IV MabThera/Rituxan plus gemcitabine and oxaliplatin (R-GemOx) in second-line or later DLBCL, and the phase III SKYGLO trial investigating the efficacy of Polivy in combination with R-CHP and Columvi® (glofitamab) versus Polivy in combination with R-CHP in 1L DLBCL. POLARIX [NCT03274492] is an international phase III, randomised, double-blind, placebo-controlled study evaluating the efficacy, safety and pharmacokinetics of Polivy® (polatuzumab vedotin) plus MabThera®/Rituxan® (rituximab), cyclophosphamide, doxorubicin, and prednisone (R-CHP) versus rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP) in people with previously untreated diffuse large B-cell lymphoma (DLBCL). Eight-hundred and seventy-nine patients were randomised 1:1 to receive either Polivy plus R-CHP plus a vincristine placebo for six cycles, followed by MabThera/Rituxan for two cycles; or R-CHOP plus a Polivy placebo for six cycles, followed by two cycles of MabThera/Rituxan. The primary outcome measure is progression-free survival (PFS) as assessed by the investigator using the Lugano Response Criteria for malignant lymphoma. PFS is a clinically meaningful disease-related outcome for patients with previously untreated DLBCL as it represents the goal of first-line therapy: decreasing the risk of disease worsening. Overall survival is a secondary endpoint in the POLARIX study. DLBCL is the most common form of non-Hodgkin lymphoma (NHL), accounting for about one in three cases of NHL.3 DLBCL is an aggressive (fast-growing) type of NHL. While it is generally responsive to treatment in the frontline, as many as 40% of people will relapse or have refractory disease, at which time salvage therapy options are limited and survival is short. 4,5 Improving treatments earlier in the course of the disease and providing much needed alternative options could help to improve long-term outcomes. Approximately 160,000 people worldwide are estimated to be diagnosed with DLBCL each year.1,6 Polivy is a first-in-class anti-CD79b antibody-drug conjugate (ADC). The CD79b protein is expressed specifically in the majority of B-cells, an immune cell impacted in some types of non-Hodgkin lymphoma (NHL), making it a promising target for the development of new therapies. Polivy binds to cancer cells such as CD79b and destroys these B-cells through the delivery of an anti-cancer agent, which is thought to minimise the effects on normal cells. Polivy is being developed by Roche using Pfizer ADC technology and is currently being investigated for the treatment of several types of NHL.
