Androgen receptor (AR) transcriptional reactivation plays a key role in the development and progression of lethal castration-resistant prostate cancer (CRPC). Recurrent alterations in the AR enable persistent AR pathway signaling and drive resistance to the treatment of second-generation antiandrogens. AR F877L, a point mutation in the ligand binding domain of the AR, was identified in patients who acquired resistance to enzalutamide or apalutamide. In parallel to our previous structure-activity relationship (SAR) studies of compound 4 (JNJ-pan-AR) and clinical stage compound 5 (JNJ-63576253), we discovered additional AR antagonists that provide opportunities for future development. Here we report a highly potent series of spirocyclic thiohydantoins as AR antagonists for the treatment of the F877L mutant and wild-type CRPC.

Abstract:

Numerous mechanisms of resistance arise in response to treatment with second-generation androgen receptor (AR) pathway inhibitors in metastatic castration-resistant prostate cancer (mCRPC). Among these, point mutations in the ligand binding domain can transform antagonists into agonists, driving the disease through activation of AR signaling. To address this unmet need, we report the discovery of JNJ-63576253, a next-generation AR pathway inhibitor that potently abrogates AR signaling in models of human prostate adenocarcinoma. JNJ-63576253 is advancing as a clinical candidate with potential effectiveness in the subset of patients who do not respond to or are progressing while on second-generation AR-targeted therapeutics.

Persistent androgen receptor (AR) activation drives therapeutic resistance to second-generation AR pathway inhibitors and contributes to the progression of advanced prostate cancer. One resistance mechanism is point mutations in the ligand binding domain of AR that can transform antagonists into agonists. The AR F877L mutation, identified in patients treated with enzalutamide or apalutamide, confers resistance to both enzalutamide and apalutamide. Compound 4 (JNJ-pan-AR) was identified as a pan-AR antagonist with potent activity against wild-type and clinically relevant AR mutations including F877L. Metabolite identification studies revealed a latent bioactivation pathway associated with 4. Subsequent lead optimization of 4 led to amelioration of this pathway and nomination of 5 (JNJ-63576253) as a clinical stage, next-generation AR antagonist for the treatment of castration-resistant prostate cancer (CRPC).

Prostate Cancer Overview Prostate cancer is a type of cancer that arises from the prostate gland. It is the second leading cause of cancer death in men in the United States. 1 in every 9 men will be diagnosed with prostate cancer during their lifetime. Prostate cancer will be diagnosed in nearly 250,000 men this year. Breaking away from a prostate tumor allows prostate cancer cells to spread. They can spread to other body parts by passing through blood vessels or lymph nodes. Cancer cells that have spread may attach to other tissues and grow to form new tumors, causing damage wherever they land. Prostate cancer symptoms vary from person to person. Some men have no symptoms at all. Common prostate cancer symptoms include blood in the urine or semen, painful ejaculation, pain or burning during urination, and others. A biopsy is a primary tool for prostate cancer diagnosis, but a doctor can use other tools to ensure that the biopsy is performed in the correct location. Doctors may, for example, use transrectal ultrasound or magnetic resonance imaging (MRI) to guide the biopsy.
