News Release - April 29, 2019
U.S. FDA Accepts New Drug Application and Grants Priority Review for DarolutamideWHIPPANY, N.J., April 29, 2019 -- (Healthcare Sales & Marketing Network) -- Bayer today announced the U.S. Food and Drug Administration (FDA) has accepted the New Drug Application (NDA) and granted Priority Review to darolutamide for the treatment of non-metastatic castration-resistant prostate cancer (nmCRPC). The NDA and Priority Review status were based on data from the Phase III ARAMIS trial in men with nmCRPC.1 Darolutamide is an investigational, non-steroidal androgen receptor (AR) antagonist with a distinct chemical structure that binds to the receptor, inhibiting the growth of prostate cancer cells.
"Bayer is committed to addressing treatment gaps that exist along the continuum of care for men with prostate cancer," said Scott Z. Fields, M.D., senior vice president and head of Oncology Development at Bayer's Pharmaceutical Division. "With the NDA acceptance and Priority Review designation, we are an important step closer to bringing darolutamide to patients as quickly as possible."
The FDA grants Priority Review for the applications of medicines that, if approved, would provide significant improvements in the safety or effectiveness of the treatment, diagnosis, or prevention of serious conditions when compared to standard applications. Bayer has also been granted Fast Track designation by the FDA for darolutamide in men with nmCRPC.
Bayer recently submitted an application to the European Medicines Agency and the Ministry of Health, Labor and Welfare (MHLW) in Japan. Bayer is also in discussions with other health authorities regarding submissions.
Darolutamide is being developed jointly by Bayer and Orion Corporation, a globally operating Finnish pharmaceutical company.
About the ARAMIS trial
The ARAMIS trial is 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 androgen deprivation therapy (ADT) as standard of care and are at high risk for developing metastatic disease. 1,509 patients were randomized in a 2:1 ratio to receive 600 mg of darolutamide twice a day or placebo along with ADT.
The primary endpoint of this trial is metastasis-free survival (MFS) defined as time between randomization and evidence of metastasis or death. The secondary endpoints of this trial are overall survival (OS), time to pain progression, time to initiation of first cytotoxic chemotherapy, time to first symptomatic skeletal event (SSE), and characterization of the safety and tolerability of darolutamide.
Darolutamide is an investigational, non-steroidal androgen receptor (AR) antagonist with a chemical structure that binds to the receptor and exhibits antagonistic activity, thereby inhibiting the receptor function and the growth of prostate cancer cells. A Phase III study in metastatic hormone-sensitive prostate cancer (ARASENS) is ongoing. Information about these trials can be found at www.clinicaltrials.gov.
Darolutamide is not approved by the U.S. FDA, the European Medicines Agency or any other health authority.
About castration-resistant prostate cancer (CRPC)
Prostate cancer is the second most commonly diagnosed malignancy in men worldwide.2 In 2018, an estimated 1.2 million men were diagnosed with prostate cancer, and about 358,000 died from the disease worldwide.2 Prostate cancer is the fifth leading cause of death from cancer in men.2 Prostate cancer results from the abnormal proliferation of cells within the prostate gland, which is part of a man's reproductive system.3 It mainly affects men over the age of 50, and the risk increases with age.4 Treatment options range from surgery to radiation treatment to therapy using hormone-receptor antagonists, i.e., substances that stop the formation of testosterone or prevent its effect at the target location.5 However, in nearly all cases, the cancer eventually becomes resistant to conventional hormone therapy.6
CRPC is an advanced form of the disease where the cancer keeps progressing even when the amount of testosterone is reduced to very low levels in the body. The field of treatment options for castration-resistant patients is evolving rapidly, but until recently, there have been no effective treatment options for CRPC patients who have rising prostate-specific antigen (PSA) levels while on ADT and no detectable metastases. In men with progressive nmCRPC, a short PSA doubling time has been consistently associated with reduced time to first metastasis and death.7
