ARAMIS Study Demonstrates Significant Improvement in Overall Survival (OS) in Patients Receiving NUBEQA (darolutamide) Plus Androgen Deprivation Therapy (ADT)

San Francisco, CA (UroToday.com)  -- Results from the preplanned final overall survival analysis of the Phase III ARAMIS (Androgen Receptor inhibiting Agent for MetastatIc-free Survival) trial that investigated NUBEQA® (darolutamide) in men with non-metastatic castration-resistant prostate cancer (nmCRPC) show a significant improvement in overall survival (OS) in patients receiving NUBEQA plus androgen deprivation therapy (ADT) compared to placebo plus ADT. Results of ARAMIS previously published show a statistically significant improvement in the primary efficacy endpoint of metastasis-free survival (MFS) of darolutamide plus ADT compared to placebo plus ADT; however OS data were not yet mature at the time of the MFS analysis. Detailed data on the updated OS and other additional endpoints as well as an update on longer term safety will be presented at an upcoming scientific meeting.

NUBEQA, an oral androgen receptor inhibitor (ARi), has been approved in the U.S., Brazil, and Japan, and filings in the European Union and other regions are underway or planned. The compound is developed jointly by Bayer and Orion Corporation, a globally operating Finnish pharmaceutical company.

About NUBEQA ® (darolutamide)

On July 30th, 2019, the FDA approved NUBEQA® (darolutamide) based on the ARAMIS trial, a randomized, double-blind, placebo-controlled, multi-center Phase III study, which evaluated the safety and efficacy of oral NUBEQA in patients with nmCRPC who were receiving a concomitant gonadotropin-releasing hormone (GnRH) analog or had a bilateral orchiectomy. In the clinical study, 1,509 patients were randomized in a 2:1 ratio to receive 600 mg of NUBEQA orally twice daily or placebo plus ADT. The primary efficacy endpoint was MFS, defined as the time from randomization to the time of first evidence of blinded independent central review (BICR)-confirmed distant metastasis or death due to any cause within 33 weeks after the last evaluable scan, whichever occurred first. NUBEQA plus ADT demonstrated a statistically significant improvement in MFS, with a median MFS of 40.4 months versus 18.4 months with placebo plus ADT [HR=0.41, 95% CI (0.34, 0.50), p<0.0001].

Adverse reactions occurring more frequently in the NUBEQA arm (≥2 % over placebo) were fatigue (16% versus 11%), pain in extremity (6% versus 3%) and rash (3% versus 1%). NUBEQA was not studied in women and there is a warning and precaution for embryo-fetal toxicity.

NUBEQA is an androgen receptor inhibitor (ARi) with a distinct chemical structure that competitively inhibits androgen binding, AR nuclear translocation, and AR-mediated transcription.1 A Phase III study in metastatic hormone-sensitive prostate cancer (ARASENS) is ongoing. Information about this trial can be found at www.clinicaltrials.gov.

INDICATION
NUBEQA is approved for the treatment of patients with non-metastatic castration-resistant prostate cancer (nmCRPC).1
