| Description | ODM-201 is a potent androgen receptor (AR) antagonist with an IC50 of 26 nM in AR-HEK293 cells.In Vitro:In competitive AR binding assays, the inhibition constant (Ki) values of ODM-201 are 11 nM. ODM-201and ORM-15341 suppresse androgen-induced cell proliferation more efficaciously than enzalutamide or ARN-509, IC50 values being 230 and 170 nM for ODM-201 and ORM-15341 vs. 410 and 420 nM for enzalutamide and ARN-509. ODM-201 has no effect on the viability of AR-negative cell lines tested, DU-145 prostate cancer cells and H1581 lung cancer cells confirming that the antiproliferative properties of ODM-201 and ORM-15341 are specific to AR-dependent PC cells[1].In Vivo:ODM-201 showes a significant antitumor activity with both doses, 50 mg/kg twice daily being more efficacious compared to castrated, untreated mice (p < 0.001) or enzalutamide (p = 0.0245), which also showes inhibition of tumor growth (p < 0.05) vs. castrated, untreated mice. Further, there is no sign of treatment-related toxicities; the body weights of mice treated with ODM-201 twice daily do not decrease significantly during the treatment[1]. References: | |||||

ODM-201 is a new-generation inhibitor of androgen receptor with Ki value of 11 nM [1].
Androgen receptor is a type of nuclear receptor that is activated by androgen and functions as a DNA-binding transcription factor that regulates gene expression. Activation of androgen receptor (AR) is crucial for prostate cancer growth [1].
ODM-201 is a high-affinity and potent androgen receptor antagonist. In competitive AR binding assays, ODM-201 exhibited Ki value of 11 nM. In AR-HEK293 cells stably expressing full-length human AR (hAR) and an androgen-responsive luciferase reporter gene construct, ODM-201 and its major metabolite ORM-15341 inhibited AR-mediated transactivation with IC50 values of 26 nM and 38 nM. In human U2-OS osteosarcoma cells expressing wtAR or mutant AR(F876L), AR(W741L), or AR(T877A), ODM-201 and ORM-15341 also functioned as full antagonists. in AR overexpressing HS-HEK293 cells, ODM-201 inhibited the androgen-induced nuclear translocation of overexpressed AR. In the VCaP cell line with endogenous AR gene amplification and AR overexpression, ODM-201 inhibited androgen-induced cell proliferation with IC50 value of 230 nM.
In castrated male nude mice with subcutaneously injected VCaP cells, orally treatment with ODM-201 (50 mg/kg) once (qd) or twice daily (bid) for 37 days, ODM-201 showed a significant antitumor activity with both doses. There was no sign of treatment-related toxicities. In orthotopic VCaP tumor-bearing intact nude mice, ODM-201 (50 mg/kg, bid) significantly inhibited tumor growth but did not affect the testosterone levels in serum. ODM-201 couldn’t penetrate the blood-brain barrier [1].

Discovery of ODM-201, a new-generation androgen receptor inhibitor targeting resistance mechanisms to androgen signaling-directed prostate cancer therapies.[Pubmed:26137992]
Sci Rep. 2015 Jul 3;5:12007.
Activation of androgen receptor (AR) is crucial for prostate cancer growth. Remarkably, also castration-resistant prostate cancer (CRPC) is dependent on functional AR, and several mechanisms have been proposed to explain the addiction. Known causes of CRPC include gene amplification and overexpression as well as point mutations of AR. We report here the pharmacological profile of ODM-201, a novel AR inhibitor that showed significant antitumor activity and a favorable safety profile in phase 1/2 studies in men with CRPC. ODM-201 is a full and high-affinity AR antagonist that, similar to second-generation antiandrogens enzalutamide and ARN-509, inhibits testosterone-induced nuclear translocation of AR. Importantly, ODM-201 also blocks the activity of the tested mutant ARs arising in response to antiandrogen therapies, including the F876L mutation that confers resistance to enzalutamide and ARN-509. In addition, ODM-201 reduces the growth of AR-overexpressing VCaP prostate cancer cells both in vitro and in a castration-resistant VCaP xenograft model. In contrast to other antiandrogens, ODM-201 shows negligible brain penetrance and does not increase serum testosterone levels in mice. In conclusion, ODM-201 is a potent AR inhibitor that overcomes resistance to AR-targeted therapies by antagonizing both overexpressed and mutated ARs. ODM-201 is currently in a phase 3 trial in CRPC.
ODM-201: a new-generation androgen receptor inhibitor in castration-resistant prostate cancer.[Pubmed:26313416]
Expert Rev Anticancer Ther. 2015;15(9):1007-17.
Androgen deprivation therapy is the standard of care for patients with advanced hormone-sensitive prostate cancer. Despite an initial response, most patients progress to castration-resistant prostate cancer (CRPC). The realization that CRPC remains driven by androgen receptor (AR) signaling has formed the basis for a new generation of agents targeting the AR axis. Two of these agents, abiraterone acetate and enzalutamide, have been shown to prolong overall survival in patients with CRPC. Several other AR inhibitors are currently in development for the treatment of CRPC. The present article reviews ODM-201, a new-generation AR inhibitor with a unique molecular structure, in the treatment of CRPC. The design of an ongoing Phase III trial (ARAMIS) of ODM-201 in men with non-metastatic CRPC is also discussed, at a disease stage for which there is currently no approved treatment.
Pharmacokinetics, Antitumor Activity, and Safety of ODM-201 in Patients with Chemotherapy-naive Metastatic Castration-resistant Prostate Cancer: An Open-label Phase 1 Study.[Pubmed:26463318]
Eur Urol. 2016 May;69(5):834-40.
BACKGROUND: ODM-201 is a novel second-generation androgen receptor inhibitor for the treatment of metastatic castration-resistant prostate cancer (mCRPC). OBJECTIVE: To evaluate the pharmacokinetics of ODM-201 tablet products and preliminary long-term safety, tolerability, and antitumor activity of ODM-201 in chemotherapy-naive men with mCRPC. DESIGN, SETTING, AND PARTICIPANTS: Thirty patients were enrolled in this open-label phase 1 trial. Patients received a single 600-mg dose of ODM-201 in capsules with food and one 600-mg dose of ODM-201 tablet product (TabA or TabB) with food and in the fasted state in a random order. In the extension, patients received 600mg twice daily ODM-201 taken with food in capsules. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: We analyzed the pharmacokinetics of ODM-201 tablet formulations. Safety and tolerability were assessed until disease progression or an intolerable adverse event (AE). Antitumor activity was assessed by prostate-specific antigen (PSA) levels and imaging. RESULTS AND LIMITATIONS: The capsule:TabA ratio of area under the concentration-time curve from time zero to the last sample at 48h was 1.06 (90% confidence interval [CI], 0.91-1.24); the capsule:TabB ratio was 0.97 (90% CI, 0.82-1.14). At week 12, 25 of 30 patients (83%) had a PSA response (>/=50% reduction from baseline). Median time to radiographic progression was 66 wk (95% CI, 41-79). Most common AEs were fatigue (n=4 [13%]) and nausea (n=4 [13%]). CONCLUSIONS: The study showed that the tablet formulation of ODM-201 had similar pharmacokinetics compared with the capsule. Treatment with a 600-mg twice daily dose of ODM-201 provided anticancer activity and was well tolerated in men with chemotherapy-naive mCRPC. PATIENT SUMMARY: The findings of this study showed that ODM-201 is well tolerated and provided antitumor activity in chemotherapy-naive patients with metastatic castration-resistant prostate cancer (mCRPC) and that the 300-mg tablet formulation can be used in further clinical studies. A phase 3 trial with ODM-201 600mg twice daily in patients with non-mCRPC is ongoing.
