Orion's and Bayer's darolutamide shows substantial efficacy and a favourable safety profile in the treatment of prostate cancer in the ARAMIS trial - Seite 4

The primary endpoint of this trial is MFS defined as time between randomization and evidence of metastasis or death. The secondary endpoints of this trial are OS, time to pain progression, time to initiation of first cytotoxic chemotherapy, time to first SSE, and characterization of the safety and tolerability of darolutamide.

About castration-resistant prostate cancer (CRPC)

Prostate cancer is the second most commonly diagnosed malignancy in men worldwide. In 2018, an estimated 1.2 million men were diagnosed with prostate cancer, and about 358,000 died from the disease worldwide. Prostate cancer is the fifth leading cause of death from cancer in men. Prostate cancer results from the abnormal proliferation of cells within the prostate gland, which is part of a man's reproductive system. It mainly affects men over the age of 50, and the risk increases with age. 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. However, in nearly all cases, the cancer eventually becomes resistant to conventional hormone therapy.

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.

About darolutamide

Darolutamide is a non-steroidal  androgen receptor antagonist 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. In addition to the Phase III trial ARAMIS in men with nmCRPC, darolutamide 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.
