Bayer submits application for third indication of darolutamide in the EUBayer submits application for third indication of darolutamide in the EU

Submission is based on positive results from the pivotal Phase III ARANOTE trial, which showed that darolutamide plus androgen deprivation therapy (ADT) significantly reduced the risk of radiological progression or death by 46% compared to placebo plus ADT in patients with metastatic hormone-sensitive prostate cancer (mHSPC) / Darolutamide plus ADT now has positive data both with and without docetaxel based on two pivotal Phase III studies in patients with mHSPC / If regulatory approval is granted in this additional indication, physicians could have greater flexibility to tailor treatment to individual patient needs

Berlin, October 14, 2024 – Bayer today announced the submission of an application to the European Medicines Agency (EMA) for the oral androgen receptor inhibitor (ARi) darolutamide. Bayer is seeking approval for the use of darolutamide in combination with androgen deprivation therapy (ADT) in patients with metastatic hormone-sensitive prostate cancer (mHSPC). The compound is already approved in mHSPC, under the brand name Nubeqa™, in combination with ADT and docetaxel in over 80 markets around the world. The compound is also approved in combination with ADT for the treatment of patients with non-metastatic castration-resistant prostate cancer (nmCRPC) who are at high risk of developing metastatic disease in more than 85 countries around the world.

“Each man with metastatic hormone-sensitive prostate cancer has unique needs. It’s crucial to equip physicians with options to tailor treatment plans to the individual, whether that is with or without chemotherapy,” said Christine Roth, Executive Vice President, Global Product Strategy and Commercialization and Member of the Pharmaceuticals Leadership Team at Bayer. “Our ambition is to redefine what it means to live with prostate cancer at different stages of the disease, extending survival and delaying disease progression, while maintaining daily living.”

Results from the Phase III ARANOTE trial, on which this new submission is based, showed that darolutamide plus ADT significantly reduced the risk of radiological progression or death by 46% compared to placebo plus ADT (HR 0.54; 95% CI 0.41–0.71; P<0.0001), in patients with mHSPC. Consistent benefits in radiological progression-free survival (rPFS) were observed across prespecified subgroups, including patients with high- and low-volume mHSPC. Treatment-emergent adverse events (TEAEs) were low and similar between treatment groups and the safety analysis reconfirmed the established tolerability profile of darolutamide as observed in the ARAMIS and ARASENS trials. The ARANOTE results were simultaneously presented at the 2024 ESMO Congress and published in The Journal of Clinical Oncology.

Darolutamide is developed jointly by Bayer and Orion Corporation, a globally operating Finnish pharmaceutical company.

About the ARANOTE Trial
The ARANOTE trial is a randomized, double-blind, placebo-controlled Phase III study designed to assess the efficacy and safety of darolutamide plus ADT in patients with mHSPC. 669 patients were randomized to receive 600mg of darolutamide twice daily or matching placebo in addition to ADT.

The primary endpoint of this study is rPFS, measured as time from randomization to date of first documented radiological progressive disease or death due to any cause, whichever occurs first. Secondary endpoints include overall survival (time to death from any cause), time to first castration resistant event, time to initiation of subsequent anti-cancer therapy, time to prostate-specific antigen (PSA) progression, PSA undetectable rates, time to pain progression, and safety assessments.

About darolutamide (Nubeqa™)
Darolutamide is an oral ARi with a distinct chemical structure that binds to the androgen receptor with high affinity and exhibits strong antagonistic activity, thereby inhibiting the receptor function and the growth of prostate cancer cells while minimizing side effects. Darolutamide also reduces the risk of interactions with other medications. The low potential for blood-brain barrier penetration for darolutamide is supported by preclinical models and neuroimaging data in healthy humans. This is also supported by the overall low incidence of central nervous system (CNS)-related adverse events (AEs) compared to placebo as seen in the ARAMIS Phase III trial and the maintained verbal learning and memory observed in the darolutamide arm of the Phase II ODENZA trial.

A robust clinical development program is underway investigating darolutamide across various stages of prostate cancer. The program includes the Phase III ARASTEP trial evaluating darolutamide plus ADT compared to ADT alone in hormone-sensitive high-risk biochemical recurrence (BCR) prostate cancer, who have no evidence of metastatic disease by conventional imaging and a positive PSMA PET/CT at baseline. Furthermore, darolutamide is also being investigated in the collaborative Phase III DASL-HiCaP (ANZUP1801) trial led by the Australian and New Zealand Urogenital and Prostate Cancer Trials Group (ANZUP). The study evaluates darolutamide as an adjuvant treatment for localized prostate cancer with very high risk of recurrence.

About Metastatic Hormone-Sensitive Prostate Cancer
Prostate cancer is the second most common cancer in men and the fifth most common cause of cancer death in men worldwide.1 In 2022, an estimated 1.5 million men were diagnosed with prostate cancer, and about 397,000 died from the disease worldwide.Prostate cancer diagnoses are projected to increase to 2.9 million by 2040.2

At the time of diagnosis, most men have localized prostate cancer, meaning their cancer is confined to the prostate gland and can be treated with curative surgery or radiotherapy. mHSPC is a stage in the disease where the cancer has spread outside of the prostate to other parts of the body. Up to 10% of men will present with mHSPC when first diagnosed.3,4,5 For patients with mHSPC, ADT is the cornerstone of treatment, often in combination with chemotherapy docetaxel and/or an androgen receptor inhibitor (ARi). Despite treatment, most men with mHSPC will eventually progress to castration-resistant prostate cancer (CRPC), a condition with limited survival.
