Abstract:
Prostate cancer is one of the leading causes of cancer related death in men, and remains incurable in the metastatic setting. Despite the initial response to androgen deprivation, the disease gradually progresses to a hormone-refractory state due to cumulative genetic alterations in tumour cells or the microenvironment. Docetaxel represents the first chemotherapeutic agent with a small survival benefit for metastatic hormone-refractory prostate cancer (HRPC). In an attempt to improve survival benefit, several novel drugs targeting specific pathways involved in cell signaling, proliferation, angiogenesis, apoptosis and immune modulation are currently under investigation either as single agents or in combination with cytotoxic drugs. Clinical trials evaluate the inhibition of prostate cancer cells growth by targeting the nuclear receptor of vitamin D alongside cytotoxic therapy. Angiogenesis inhibitors as well as epidermal growth factor receptor blockage are also under clinical investigation in several combinations. Immunomodulatory agents and autologous dendritic cells or allogenic whole cell vaccines have progressed up to phase III trials. New drugs targeting bone microenvironment or apoptotic and proliferation pathways may enhance antitumour activity of chemotherapy in HRCP. Given the complexity of mechanisms underlying prostate cancer progression, future therapeutic strategies should rely on multidisciplinary approaches, thus exploiting newer molecular targets in concert with immunotherapy and cytotoxic chemotherapy. Here, we review the latest clinical evidence regarding the use of novel agents in HRPC.
Insights
Novel treatments are being investigated to improve survival for men with advanced prostate cancer (HRPC). These therapies target specific pathways and combine new drugs with chemotherapy for better outcomes.
Area of Science:
- Oncology
- Urology
- Pharmacology
Background:
- Prostate cancer is a leading cause of cancer death in men, often incurable in the metastatic stage.
- Hormone-refractory prostate cancer (HRPC) progresses despite initial androgen deprivation due to genetic alterations.
- Docetaxel offers a limited survival benefit for HRPC, necessitating improved therapeutic strategies.
Purpose of the Study:
- To review the latest clinical evidence on novel agents for metastatic hormone-refractory prostate cancer (HRPC).
- To explore emerging therapeutic strategies targeting specific pathways involved in prostate cancer progression.
- To discuss the potential of multidisciplinary approaches combining novel drugs, immunotherapy, and chemotherapy.
Main Methods:
- Review of current clinical trials and evidence regarding novel agents in HRPC.
- Investigation of drugs targeting cell signaling, proliferation, angiogenesis, apoptosis, and immune modulation.
- Analysis of combinations of novel agents with cytotoxic drugs and immunotherapies.
Main Results:
- Several novel drugs targeting specific pathways are under investigation as single agents or in combination therapy.
- Clinical trials are evaluating vitamin D receptor agonists, angiogenesis inhibitors, and EGFR blockers.
- Immunomodulatory agents and vaccines have reached advanced clinical trial phases (Phase III).
Conclusions:
- New drugs targeting the bone microenvironment, apoptosis, and proliferation pathways show promise in enhancing chemotherapy efficacy.
- Multidisciplinary approaches are crucial for future therapeutic strategies in HRPC.
- Exploiting novel molecular targets in conjunction with immunotherapy and chemotherapy is key to improving outcomes for HRPC patients.

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...
