• Phase III ARANOTE trial met primary endpoint, significantly increasing radiological progression-free survival (rPFS) with NUBEQA plus androgen deprivation therapy (ADT) compared to placebo plus ADT
  • Results were consistent with NUBEQA’s established safety profile with no new signals observed
  • NUBEQA now has positive mHSPC data both with and without docetaxel based on two pivotal Phase III studies
  • Bayer plans to present the pivotal data at a forthcoming scientific congress and discuss these data with the U.S. Food and Drug Administration (FDA) for regulatory approval

WHIPPANY, NJ, USA I July 17, 2024 I The Phase III ARANOTE trial, investigating NUBEQA® (darolutamide) plus androgen deprivation therapy (ADT) in patients with metastatic hormone-sensitive prostate cancer (mHSPC), has met its primary endpoint of radiological progression-free survival (rPFS). NUBEQA plus ADT demonstrated a statistically significant and clinically meaningful increase in rPFS compared to placebo plus ADT.

Results were consistent with NUBEQA’s established safety profile with no new signals observed. Detailed results from this randomized, double-blind, placebo-controlled trial are planned to be presented at a forthcoming scientific congress.

NUBEQA is currently indicated in the U.S. for the treatment of adult patients with mHSPC in combination with docetaxel and for the treatment of adult patients with non-metastatic castration-resistant prostate cancer (nmCRPC).1

“We are excited to share the positive results from this Phase III trial. Following potential regulatory approval, physicians will be able to tailor NUBEQA treatment plans with or without docetaxel based on individual patient’s needs,” said Christian Rommel, Ph.D., Head of Research and Development at Bayer’s Pharmaceuticals Division. “Today’s results build on the established efficacy and tolerability profile of NUBEQA. We are looking forward to future outcomes of our clinical development program investigating the compound across multiple prostate cancer stages and indications.”

Bayer plans to present the pivotal data at a forthcoming scientific conference and discuss these data with the U.S. FDA regarding submission for regulatory approval.

About the ARANOTE Trial

The ARANOTE trial (NCT04736199) is a randomized, double-blind, placebo-controlled Phase III study designed to assess the efficacy and safety of NUBEQA plus androgen deprivation therapy (ADT) in patients with metastatic hormone-sensitive prostate cancer (mHSPC). 669 patients were randomized to receive 600mg of NUBEQA twice daily or matching placebo in addition to ADT.

The primary endpoint of this study is radiological progression-free survival (rPFS), as measured as the time from the date of randomization to the date of first documentation of radiological progressive disease or death due to any cause, whichever occurs first. Secondary endpoints include overall survival, time from randomization to the date of death from any cause, time from randomization to the date of 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 NUBEQA® (darolutamide)1

NUBEQA® (darolutamide) is an androgen receptor inhibitor (ARi) with a distinct chemical structure that competitively inhibits androgen binding, AR nuclear translocation, and AR-mediated transcription.

NUBEQA is being evaluated in a robust clinical development program, which includes studies across various stages of prostate cancer, including in the Phase III ARANOTE trial evaluating NUBEQA plus androgen deprivation therapy (ADT) versus ADT alone for mHSPC, the ARASTEP Phase III trial evaluating NUBEQA plus ADT versus ADT alone in HSPC patients with high-risk biochemical recurrence (BCR) and no evidence of metastatic disease by conventional imaging and a positive PSMA PET/CT at baseline, as well as in the Australian and New Zealand Urogenital and Prostate Cancer Trials Group (ANZUP) led international Phase III co-operative group DASL-HiCaP (ANZUP1801) trial evaluating NUBEQA as an adjuvant treatment for localized prostate cancer with very high risk of recurrence. Information about these trials can be found at www.clinicaltrials.gov.

NUBEQA is currently indicated in the U.S. in combination with docetaxel and ADT for the treatment of adult patients with mHSPC and for the treatment of adult patients with non-metastatic castration-resistant prostate cancer (nmCRPC) with ADT.1

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

INDICATIONS

NUBEQA® (darolutamide) is an androgen receptor inhibitor indicated for the treatment of adult patients with:

  • Non-metastatic castration-resistant prostate cancer (nmCRPC)
  • Metastatic hormone-sensitive prostate cancer (mHSPC) in combination with docetaxel

For important risk and use information about NUBEQA, please see the accompanying full Prescribing Information.

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.2 In 2020, an estimated 1.4 million men were diagnosed with prostate cancer, including almost 300,000 cases in the U.S., and about 375,000 died from the disease worldwide.3,4

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. Upon relapse when the disease will metastasize or spread, androgen deprivation therapy (ADT) is the cornerstone of treatment for this hormone-sensitive disease. Approximately 10% of men will already present with mHSPC when first diagnosed.5,6,7 Men with metastatic hormone-sensitive prostate cancer (mHSPC) will start their treatment with hormone therapy, such as ADT, androgen receptor inhibitor (ARi) plus ADT or a combination of the chemotherapy docetaxel and ADT. Despite this treatment, most men with mHSPC will eventually progress to castration-resistant prostate cancer (CRPC), a condition with limited survival.
