Abstract:
The androgen receptor drives the growth of metastatic castration-resistant prostate cancer. This has led to the development of multiple novel drugs targeting this hormone-regulated transcription factor, such as enzalutamide – a potent androgen receptor antagonist. Despite the plethora of possible treatment options, the absolute survival benefit of each treatment separately is limited to a few months. Therefore, current research efforts are directed to determine the optimal sequence of therapies, discover novel drugs effective in metastatic castration-resistant prostate cancer and define patient subpopulations that ultimately benefit from these treatments. Molecular studies provide evidence on which pathways mediate treatment resistance and may lead to improved treatment for metastatic castration-resistant prostate cancer. This review provides, firstly a concise overview of the clinical development, use and effectiveness of enzalutamide in the treatment of advanced prostate cancer, secondly it describes translational research addressing enzalutamide response vs resistance and lastly highlights novel potential treatment strategies in the enzalutamide-resistant setting.
Insights
Enzalutamide treats advanced prostate cancer by targeting the androgen receptor. Research explores optimizing its use and developing new strategies for enzalutamide-resistant metastatic castration-resistant prostate cancer.
Area of Science:
- Oncology
- Pharmacology
Background:
- Androgen receptor (AR) signaling drives metastatic castration-resistant prostate cancer (mCRPC) growth.
- Novel drugs like enzalutamide target AR, but survival benefits are limited.
- Optimal sequencing and novel therapies are needed for advanced prostate cancer.
Purpose of the Study:
- To review enzalutamide's clinical use in advanced prostate cancer.
- To discuss translational research on enzalutamide response and resistance.
- To highlight novel treatment strategies for enzalutamide-resistant mCRPC.
Main Methods:
- Literature review of clinical trials and translational studies.
- Analysis of enzalutamide's efficacy and resistance mechanisms.
- Synthesis of emerging therapeutic approaches for mCRPC.
Main Results:
- Enzalutamide is a key treatment for advanced prostate cancer.
- Understanding AR pathway resistance is crucial for treatment efficacy.
- Several novel strategies are emerging for resistant prostate cancer.
Conclusions:
- Optimizing enzalutamide use and combination therapies is essential.
- Further research into resistance mechanisms will guide future mCRPC treatments.
- Novel therapeutic strategies show promise for improving outcomes in advanced prostate cancer.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
