On February 3, 2021 Bayer reported The Chinese National Medical Products Administration (NMPA) has approved Nubeqa (darolutamide) for the treatment of patients with non-metastatic castration-resistant prostate cancer (nmCRPC) who are at high risk of developing metastatic disease (Press release, Bayer, FEB 3, 2021, View Source;ref=irrefndcd [SID1234574570]). Nubeqa has already received regulatory approval in several other markets around the world, including the U.S., the European Union (EU), Brazil, Canada and Japan. Filings in other regions are underway or planned. Nubeqa is developed jointly by Bayer and Orion Corporation, a globally operating Finnish pharmaceutical company.

"We are pleased that Nubeqa, a differentiated treatment option that extends life while preserving quality of life for men with nmCRPC, will now be available for patients in China," said Scott Z. Fields, M.D., senior vice president and head of Oncology Development of Bayer AG’s Pharmaceutical Division. "Following this and the recent approval of Xofigo (Radium-223 dichloride) for patients with castration-resistant prostate cancer (CRPC) and symptomatic bone metastasis, we can now bring two therapeutic options to the increasing number of men living with prostate cancer in China to address their multiple medical needs across disease stages."
This approval in China is based on the Phase III ARAMIS trial evaluating the efficacy and safety of darolutamide plus androgen deprivation therapy (ADT) compared to placebo plus ADT, showing a statistically significant improvement in the primary efficacy endpoint of metastasis-free survival (MFS), with a median of 40.4 months for darolutamide plus ADT versus 18.4 months for placebo plus ADT (HR=0.41, 95% CI 0.34-0.50; P<0.001). The final overall survival (OS) analysis published in The New England Journal of Medicine showed men receiving darolutamide plus ADT demonstrated a significant improvement in OS compared to placebo plus ADT, with a 31 percent reduction in risk of death (HR=0.69, 95% CI 0.53-0.88; p=0.003). Darolutamide has demonstrated favorable safety and tolerability, even with longer follow-up, with discontinuation of treatment due to adverse events (AEs) occurring in 9 percent of patients in both arms of the study. Results from the ARAMIS trial also confirm the low potential for central nervous system (CNS) side effects, such as falls, mental impairment and cognitive impairment, expected with darolutamide plus ADT.

"Prostate cancer is the sixth most common cancer in men in China," (4) said Prof. Huang Jian, SUN YAT-SEN Memorial Hospital, SUN YAT-SEN University. "Prostate cancer that is treated with ADT but progresses as evidenced by rising prostatic-specific antigen (PSA) levels, even when the amount of testosterone is reduced to very low levels in the body, and without radiographic evidence of distant metastasis, is known as nmCRPC. About one-third of men with nmCRPC receiving ADT alone go on to develop metastases within two years, (5),(6) so early diagnosis and timely intervention at this stage is critical. As these men typically have no symptoms and are leading active lives, it is important to have treatment options that delay disease progression and prolong their overall survival (OS), while minimizing burdensome treatment side effects, so they can maintain their lifestyle with little disruption."
About Nubeqa (darolutamide)
Darolutamide is approved under the brand name Nubeqa for the treatment of men with non-metastatic castration-resistant prostate cancer (nmCRPC), who are at high risk of developing metastatic disease.
Nubeqa is an oral androgen receptor inhibitor (ARi) with a distinct chemical structure that binds to the receptor with high affinity and exhibits strong antagonistic activity, thereby inhibiting the receptor function and the growth of prostate cancer cells. The compound is also being investigated in a Phase III study in metastatic hormone-sensitive prostate cancer (ARASENS). Information about these trials can be found at www.clinicaltrials.gov.
About the ARAMIS trial
The ARAMIS trial was a randomized, Phase III, multi-center, double-blind, placebo-controlled trial evaluating the safety and efficacy of oral darolutamide in patients with nmCRPC who are currently being treated with ADT and are at high risk for developing metastatic disease. In the clinical study, 1,509 patients were randomized in a 2:1 ratio to receive 600 mg of darolutamide orally twice daily or placebo along with ADT. Patients with a history of seizure were allowed in the study.
