LYNPARZA® (olaparib) in Combination With Bevacizumab, and as Monotherapy, Demonstrates Clinically Meaningful Long-Term Survival in Certain Patients With First-Line Advanced Ovarian Cancer in Exploratory Analyses of Two Phase 3 Trials

RAHWAY, N.J.--(BUSINESS WIRE)-- AstraZeneca and Merck & Co. known as MSD outside of the United States and Canada, today announced long-term follow-up results from the Phase 3 PAOLA-1 and SOLO-1 trials in first-line advanced ovarian cancer, which represent the longest-term data for any PARP inhibitor in this setting.

These results were presented on Sept. 9 at the European Society for Medical Oncology (ESMO) 2022 Congress, and the SOLO-1 results were published in the Journal of Clinical Oncology.

Ovarian cancer is one of the most common gynecologic cancers and has the worst prognosis and highest mortality rate. More than two-thirds of patients with ovarian cancer are diagnosed with advanced disease, and approximately 50-70% of these patients die within five years. Roughly half of patients with advanced ovarian cancer have homologous recombination deficiency (HRD)-positive tumors, including those with a BRCA mutation, and one in four women have a BRCA mutation.

Five-year follow-up and final OS results from Phase 3 PAOLA-1 trial (abstract #LBA29)

The Phase 3 PAOLA-1 trial evaluated LYNPARZA in combination with bevacizumab as first-line maintenance therapy in patients with advanced ovarian cancer, who were without evidence of disease after surgery or following response to platinum-based chemotherapy. Final overall survival (OS), a key secondary endpoint, in those who received LYNPARZA plus bevacizumab was 56.5 months versus 51.6 months with bevacizumab alone (HR=0.92 [95% CI, 0.76-1.12]; p=0.4118) in patients with newly diagnosed advanced ovarian cancer. These OS results were not statistically significant.

In an exploratory subgroup analysis of HRD-positive patients, LYNPARZA plus bevacizumab provided a clinically meaningful improvement in OS, reducing the risk of death by 38% (HR=0.62 [95% CI, 0.45-0.85]) versus bevacizumab alone. 65.5% of patients who received LYNPARZA plus bevacizumab were still alive at five years versus 48.4% who received bevacizumab alone. LYNPARZA plus bevacizumab also improved median progression-free survival (PFS) to nearly four years (46.8 months) versus 17.6 months with bevacizumab plus placebo, and 46.1% of patients who received LYNPARZA in combination with bevacizumab remain progression free versus 19.2% of patients who received bevacizumab alone. The safety and tolerability profile of LYNPARZA in this trial was in line with that observed in prior clinical trials, with no new safety signals. Adverse events of special interest for LYNPARZA in combination with bevacizumab versus bevacizumab alone included myelodysplastic syndrome/acute myeloid leukemia/aplastic anemia (1.7% vs. 2.2%), new primary malignancies (4.1% vs. 3.0%) and pneumonitis/interstitial lung disease/bronchiolitis (1.3% vs. 0.7%).

Seven-year follow-up from Phase 3 SOLO-1 trial (abstract #517O)

The Phase 3 SOLO-1 trial evaluated LYNPARZA as monotherapy as first-line maintenance therapy in patients with advanced ovarian cancer, who were without evidence of disease after surgery or following response to platinum-based chemotherapy. In the trial, LYNPARZA demonstrated a clinically meaningful improvement in OS versus placebo in patients with germline BRCA-mutated (gBRCAm) newly diagnosed advanced ovarian cancer, reducing the risk of death by 45% (HR=0.55 [95% CI, 0.40-0.76]; p=0.0004) versus placebo (not statistically significant). Median OS was not reached with LYNPARZA versus 75.2 months with placebo. At the seven-year descriptive OS analysis, 67% of LYNPARZA patients were alive versus 47% of placebo patients (44% of whom had a subsequent PARP inhibitor), and 45% of LYNPARZA patients versus 21% of placebo patients were alive and had not received a first subsequent treatment.

Additional data showed median time to first subsequent therapy (TFST) was 64.0 months with LYNPARZA versus 15.1 months with placebo. The safety and tolerability profile of LYNPARZA in this trial was in line with that observed in prior clinical trials, with no new safety signals. The most common treatment-emergent adverse events (≥20%) were nausea (78%), fatigue (64%), vomiting (40%), anemia (40%), diarrhea (35%), arthralgia (29%), constipation (28%), abdominal pain (26%), headache (23%), neutropenia (23%), dysgeusia (22%), dizziness (20%) and decreased appetite (20%).

Please see Important Safety Information for LYNPARZA after the “About SOLO-1” section below.

Professor Isabelle Ray-Coquard, principal investigator from the PAOLA-1 trial and president of the GINECO group said, “For women facing an advanced ovarian cancer diagnosis who are HRD-positive, a targeted treatment in the first-line maintenance setting is critical to helping them live longer. These latest results at the five-year landmark demonstrate that olaparib with bevacizumab reduces the risk of death by 38% in HRD-positive patients compared to bevacizumab alone, further reinforcing the clinically meaningful long-term survival benefit of this combination. This should be promising news for both clinicians and patients, as we see these additional data show that this combination may allow patients more time with family and loved ones. These results also highlight the importance of biomarker testing as part of a precision medicine approach to guide treatment decisions in ovarian cancer patients.”

Professor Paul Di Silvestro, investigator from the SOLO-1 trial and director of the program in women’s oncology at Women and Infants Hospital in Providence, Rhode Island, said, “The long-term results from SOLO-1 confirm that LYNPARZA continues to elicit a clinically meaningful improvement in overall survival in the first-line maintenance setting for more than seven years. Achieving long-term survival for patients with newly diagnosed advanced ovarian cancer is critical because the first-line setting offers the greatest potential to impact patient survival.”

Susan Galbraith, executive vice president, oncology R&D, AstraZeneca, said, “Historically, the five-year survival rate of newly diagnosed patients with advanced ovarian cancer is 30-50%. In that context, it is phenomenal to share the long-term overall survival data from both PAOLA-1 and SOLO-1, with two out of three patients still alive in these trials. We continue to believe in LYNPARZA’s ability to help biomarker-selected patients with advanced ovarian cancer to achieve better outcomes.”

Dr. Eliav Barr, senior vice president, head of global clinical development and chief medical officer, Merck Research Laboratories, said, “These latest data from the PAOLA-1 and SOLO-1 trials further highlight the importance of HRD testing, including for BRCA1/2 mutations, for all newly diagnosed advanced ovarian cancer patients at the point of diagnosis. Maintenance therapy with LYNPARZA may provide certain patients with HRD-positive or BRCA-mutated advanced ovarian cancer the opportunity to live longer.”

Summary of PAOLA-1 & SOLO-1 results

LYNPARZA is approved as maintenance treatment of platinum-sensitive relapsed ovarian cancer and as both monotherapy and in combination with bevacizumab for the first-line maintenance treatment of BRCAm and HRD-positive advanced ovarian cancer, respectively. Select patients for therapy based on an FDA-approved companion diagnostic for LYNPARZA.

About PAOLA-1

PAOLA-1 is a Phase 3, double-blinded trial evaluating the efficacy and safety of LYNPARZA added to standard-of-care bevacizumab versus bevacizumab alone as a first-line maintenance treatment for patients with newly diagnosed advanced FIGO stage III-IV high-grade serous or endometroid ovarian, fallopian tube or peritoneal cancer who had a complete or partial response to first-line treatment with platinum-based chemotherapy and bevacizumab. AstraZeneca and Merck announced in August 2019 that the trial met its primary endpoint of PFS in the overall trial population.

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 specializing in clinical and translational research in patients’ cancers and a member of the GCIG (Gynecologic Cancer InterGroup).

About SOLO-1

SOLO-1 is a Phase 3, randomized, double-blinded, placebo-controlled, multicenter trial to evaluate the efficacy and safety of LYNPARZA (300 mg twice daily) as maintenance monotherapy compared with placebo in newly diagnosed patients with advanced BRCAm ovarian cancer following platinum-based chemotherapy. The trial randomized 391 patients with a deleterious or suspected deleterious BRCA1 or BRCA2 mutation who were in clinical complete or partial response following platinum-based chemotherapy. Patients were randomized (2:1) to receive LYNPARZA or placebo for up to two years or until disease progression (at the investigator’s discretion). The primary endpoint was PFS, and key secondary endpoints included time to second disease progression or death, TFST and OS. AstraZeneca and Merck announced in June 2018 that the trial met its primary endpoint of PFS in the overall trial population.

IMPORTANT SAFETY INFORMATION

CONTRAINDICATIONS

There are no contraindications for LYNPARZA.

WARNINGS AND PRECAUTIONS

Myelodysplastic Syndrome/Acute Myeloid Leukemia (MDS/AML): Occurred in approximately 1.5% of patients exposed to LYNPARZA monotherapy, and the majority of events had a fatal outcome. The median duration of therapy in patients who developed MDS/AML was 2 years (range: <6 months to >10 years). All of these patients had previous chemotherapy with platinum agents and/or other DNA-damaging agents, including radiotherapy.

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.

Embryo-Fetal Toxicity: Based on its mechanism of action and findings in animals, LYNPARZA can cause fetal harm. A pregnancy test is recommended for 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.

Venous Thromboembolic Events: Including pulmonary embolism, occurred in 7% of patients with metastatic castration-resistant prostate cancer who received LYNPARZA plus androgen deprivation therapy (ADT) compared to 3.1% of patients receiving enzalutamide or abiraterone plus ADT in the PROfound study. Patients receiving LYNPARZA and ADT had a 6% incidence of pulmonary embolism compared to 0.8% of patients treated with ADT plus either enzalutamide or abiraterone. 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.

About LYNPARZA^® (olaparib)

LYNPARZA is a first-in-class PARP inhibitor and the first targeted treatment to potentially exploit DNA damage response (DDR) pathway deficiencies, such as BRCA mutations, to preferentially kill cancer cells. 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 tumor types with defects and dependencies in the DDR.

LYNPARZA, which is being jointly developed and commercialized by AstraZeneca and Merck, has a broad and advanced clinical trial development program, and AstraZeneca and Merck are working together to understand how it may affect multiple PARP-dependent tumors as a monotherapy and in combination across multiple cancer types.

About ovarian cancer

Ovarian cancer is the eighth most common cancer in women worldwide. Globally, there were more than 313,000 new cases of ovarian cancer in 2020 and over 207,000 deaths. The five-year survival rate newly diagnosed advanced ovarian cancer patients has typically been 30-50%. Roughly half of women with advanced ovarian cancer have homologous recombination deficiency (HRD)-positive tumors, including those with a BRCA mutation, and one in four women have a BRCA mutation. The primary aim of first-line treatment is to delay disease progression for as long as possible with the intent to achieve long-term remission.

About BRCA mutations

BRCA1 and BRCA2 (breast cancer susceptibility genes 1/2) are human genes that produce proteins responsible for repairing damaged DNA and play an important role maintaining the genetic stability of cells. 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.

About homologous recombination deficiency

Homologous recombination deficiency, which defines a subgroup of ovarian cancer, encompasses a wide range of genetic abnormalities, including BRCA mutations and beyond. As with BRCA gene mutations, HRD interferes with normal cell DNA repair mechanisms and confers sensitivity to PARP inhibitors including LYNPARZA.
