Abstract:
The androgen receptor (AR) signalling pathway remains a key driver of prostate cancer progression despite castrate levels of testosterone in advanced disease. The androgen biosynthesis inhibitor abiraterone and the anti-androgen enzalutamide have been shown to prolong survival in randomized clinical trials both pre-and post-docetaxel chemotherapy and are now in routine clinical use. With the use of these drugs and other novel survival-prolonging therapeutics, patients with advanced prostate cancer are now living longer with better quality of life. This article will review pre-clinical and clinical data for AR-targeting therapeutics for advanced prostate cancer with a focus on mechanisms of resistance and future directions for research.
Insights
Advanced prostate cancer treatments targeting the androgen receptor (AR) pathway, like abiraterone and enzalutamide, extend survival. Research focuses on resistance mechanisms and future therapies for AR-driven prostate cancer.
Area of Science:
- Oncology
- Molecular Biology
- Pharmacology
Background:
- Androgen receptor (AR) signaling drives prostate cancer progression, even at low testosterone levels in advanced stages.
- Current treatments include abiraterone and enzalutamide, which prolong survival in advanced prostate cancer patients.
Purpose of the Study:
- To review preclinical and clinical data on AR-targeting therapeutics for advanced prostate cancer.
- To focus on mechanisms of resistance to these therapies.
- To outline future research directions in AR-targeted treatment.
Main Methods:
- Review of preclinical studies on AR-targeting drugs.
- Analysis of clinical trial data for abiraterone and enzalutamide.
- Examination of resistance mechanisms in advanced prostate cancer.
Main Results:
- AR-targeting drugs like abiraterone and enzalutamide are effective in prolonging survival.
- These therapeutics are standard care for advanced prostate cancer.
- Patients are living longer with improved quality of life.
Conclusions:
- AR-signaling pathway inhibitors are crucial for advanced prostate cancer management.
- Understanding resistance mechanisms is key to developing next-generation therapies.
- Continued research is needed to optimize AR-targeted treatment strategies.

Targeted Cancer Therapies
Targets for Drug Action: Overview
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...
