Researchers want to learn if MK-5684 (the study medicine) can treat breast cancer, ovarian cancer, and endometrial cancer. MK-5684, the study medicine, is designed to treat cancer by blocking the body from making steroid hormones.
Researchers will compare MK-5684 to the standard treatments for each cancer type in this study.
The goal of this study is to learn if people who receive MK-5684 live longer without the cancer growing or spreading compared to people who receive a standard treatment.

Targeting androgen biosynthesis in prostate cancer: implications on endocrine physiology

Review

作者: Malek, Rana ; Hussain, Arif ; Kango, Ghazal ; Mannuel, Heather

Purpose of review:

Targeting specific steroidogenic enzymes is effective in decreasing testosterone synthesis, resulting in significant antitumor effects in prostate cancer. Such treatments result in disruptions of complicated and intertwining pathways with systemic physiologic consequences via effects on the adrenal gland and renin–angiotensin–aldosterone axis. This review highlights some of these aspects that need to be taken into consideration when treating patients with androgen biosynthesis inhibitors.

Recent findings:

Targeting CYP17A1, a key enzyme involved in androgen biosynthesis, is a well established treatment in prostate cancer. More recently, efforts are underway to target a gatekeeper enzyme of steroidogenesis, CYP11A1. This enzyme mediates conversion of cholesterol to pregnenolone, the first step in steroid hormone biogenesis. Studies are beginning to demonstrate antitumor effects of ODM-208, a CYP11A1 inhibitor in prostate cancer. Although anticipated to have a therapeutic role in prostate cancer, there are potential downstream effects of CYP11A1 targeting arising from suppression of the entire adrenal cortex, including long-term adrenal insufficiency and possibly cardiovascular dysregulation.

Summary:

Agents targeting androgen biosynthesis can have systemic implications. Balancing management of prostate cancer with better understanding of the mechanisms associated with potential side effects will allow for patients to obtain improved antitumor benefit while mitigating against treatment-associated adverse effects.

Targeted Inhibition of CYP11A1 in Castration-Resistant Prostate Cancer

BACKGROUND: Prostate cancer is regulated by steroid hormones, even in castration-resistant disease. ODM-208, a novel inhibitor of cytochrome P450 11A1 (which catalyzes the first step of steroid-hormone biosynthesis), was investigated in patients with heavily pretreated metastatic castration-resistant prostate cancer (mCRPC). METHODS: CYPIDES is a first-in-human phase 1 (3 + 3 design) and phase 2 study. We administered ODM-208 twice daily with glucocorticoid/mineralocorticoid replacement and ongoing androgen deprivation therapy to adults with previously treated mCRPC, regardless of androgen receptor gene (AR) ligand-binding domain mutations (phase 1) and with activating AR ligand-binding domain mutations (ARmut; phase 2). Safety, pharmacokinetics, steroid-hormone pharmacodynamics, and preliminary efficacy were the key outcomes. RESULTS: Ninety-two patients received one or more doses of ODM-208: 47 in phase 1 (20 [42.6%] with ARmut) and 45 in phase 2 (all ARmut). A dose of ODM-208 of 5 mg twice a day with dexamethasone 1 mg/fludrocortisone 0.1 mg provided a balance between decreased steroidogenesis and toxicity. Treatment-related adrenal insufficiency was the most common toxicity in phase 1 (n=17, 36.2%; necessitating ODM-208 discontinuation in one patient); this toxicity occurred in six patients (13.3%) at 5 mg twice a day in phase 2. Median circulating testosterone levels declined from 3.0 ng/dl (interquartile range, 1.3 to 6.2 ng/dl) at baseline to undetectable levels within the first week of ODM-208 5 mg twice a day treatment in 46 of 53 (87%) patients. A decrease in prostate-specific antigen levels of 50% or more occurred in 14 of 19 (73.7%) patients with ARmut and 2 of 23 (8.7%) patients with AR wild type in phase 1 and in 24 of 45 (53.3%) patients with ARmut in phase 2. CONCLUSIONS: ODM-208 potently inhibited steroid-hormone biosynthesis with the expected toxicity of adrenal insufficiency. Evidence of antitumor activity was observed in this heavily pretreated mCRPC population, especially in those with ARmut. (Funded by Orion Pharma; ClinicalTrials.gov number, NCT03436485.)

Acerand Therapeutics Initiates First-in-Human Phase I Clinical Trial of ACE-232, a Novel CYP11A1 Inhibitor for Advanced Prostate Cancer

SHANGHAI, China & INDIANAPOLIS, IN, USA I June 04, 2025 I Acerand Therapeutics, a clinical-stage biotech company focusing on the discovery and development of innovative small-molecule therapies in oncology, today announced the dosing of the first patient in its first-in-human Phase I clinical trial (NCT06801236) of ACE-232, a novel oral inhibitor of CYP11A1. The trial is being conducted in patients with metastatic castration-resistant prostate cancer (mCRPC). This multicenter Phase I study is being conducted in both the United States and China. The study comprises two parts: a dose-escalation phase (Phase IA) and a dose-optimization phase (Phase IB). The primary objectives are to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), as well as preliminary clinical activity of ACE-232, and to determine the recommended Phase II dose (RP2D). Professor Emmanuel Antonarakis, Director of Genitourinary Oncology at Masonic Cancer Center, University of Minnesota, is serving as the global coordinating Principal Investigator for the study. “I would like to congratulate the Acerand team, the research staff, and the first patient for helping us to reach this important milestone,” says Dr. Antonarakis. Preclinical data demonstrated that ACE-232 possesses superior potency, efficacy, and pharmacokinetic properties (flat PK curve and long half-life profile) compared to other investigational CYP11A1 inhibitors, including MK-5684 (Opevesostat, formerly known as ODM-208). ACE-232 showed excellent tolerability in preclinical models, presenting a wide therapeutic window for clinical development. The initiation of this trial marks a significant milestone for Acerand, representing its first clinical study in the United States and highlighting its strategic commitment to the global development of innovative cancer therapies that address major unmet medical needs. About ACE-232 ACE-232 is a highly potent and selective small-molecule inhibitor of CYP11A1, a key adrenal enzyme involved in the first and rate-limiting step of steroid hormone biosynthesis. By targeting CYP11A1, ACE-232 aims to suppress the production of androgens and other steroid hormones, offering a novel therapeutic mechanism for the treatment of androgen-dependent (including enzalutamide or abiraterone-resistant) prostate cancer. About Acerand Therapeutics Acerand Therapeutics is a biotech company dedicated to discovering and developing novel small-molecule therapies for oncology and metabolic diseases. With research and development hubs in Shanghai, China, and Indianapolis, USA, ACE-232 leverages its proprietary innovation platform and operational efficiency to deliver a highly differentiated pipeline of drug candidates from discovery to clinical trials. http://acerand.com/ SOURCE: Acerand Therapeutics
