ODM-201 offers a new therapeutic option for the treatment of prostate cancer

ODM-201 is a novel oral androgen receptor (AR) inhibitor for the treatment of advanced prostate cancer, currently preparing for Phase III clinical trials.

ODM-201 offers a new therapeutic option for the treatment of prostate cancer

Data on ODM-201 from two clinical trials (ARADES and ARAFOR), reviewing safety and efficacy of ODM-201 in chemotherapy and CYP17-inhibitor naïve patients will be presented during the 29th Annual EAU Congress in Stockholm (11-15 April 2014).

The ARADES phase I/II trial (NCT01317641 and NCT01429064) assessed the efficacy and safety of three dose levels of ODM-201 (100mg, 200mg and 700mg given twice a day) in 124 patients.

The ARAFOR trial (NCT01784757) is a bioavailability study also evaluating efficacy and safety for ODM-201 in 30 patients. The current subgroup analysis included chemotherapy and CYP17i-naïve metastatic castration resistant prostate cancer patients from the two trials. It was shown that ODM-201 daily doses between 1200-1800 mg was well tolerated, and produce marked, long-lasting declines in PSA in majority of these patients.

Professor Teuvo Tammela from the University of Tampere, Finland, comments: "ODM-201 is an exciting new therapeutic option for the treatment of prostate cancer. I am really looking forward to its further development into Phase III trials".

Prostate cancer
Prostate cancer is the most common cancer in the male population in the Western countries. Hormonal deprivation therapy allows long-lasting and effective control of cancer-related symptoms in advanced stages. Despite effective treatment strategies, in some patients with prostate cancer the disease will progress and become castration-resistant. CRPC is characterized by persistent, high level AR function and resistance to conventional anti-androgens such as bicalutamide. Effective treatment options for castrate-resistant patients are still limited, with the field evolving rapidly.

About ODM-201
ODM-201 is a novel AR inhibitor with unique chemistry that is designed to block the growth of CRPC. ODM-201 binds to AR with high affinity and inhibits receptor function by blocking the nuclear translocation of AR. Unlike other AR inhibitors, ODM-201 does not enter the brain in nonclinical models.
