Fenbendazole is an antiparasitic drug commonly used in veterinary medicine to treat worms and other parasites in animals. It’s in the same broad drug class as mebendazole (used in humans for parasitic infections).

In recent years, fenbendazole has attracted attention because laboratory and animal studies have suggested it may have anti-cancer effects — such as interfering with cancer cell metabolism, blocking cell division, and reducing tumor growth. These findings led some researchers and patients to speculate about its potential role in treating cancers, including prostate cancer.

However, it’s important to emphasize that fenbendazole is not approved for human use or for cancer treatment, and there are no completed or large-scale clinical trials proving its safety or effectiveness in people with prostate cancer. A few early-stage or preclinical studies have examined how fenbendazole might interact with cancer pathways, but the research is still in its infancy.

In short: fenbendazole shows some anti-cancer activity in the lab, but its role in prostate cancer remains unproven and experimental. Anyone considering it should only explore it within the context of a regulated clinical trial and with medical consultation and supervision.

Advanced prostate cancer means the disease has spread beyond the prostate or no longer responds to treatments that lower testosterone. It can be locally advanced, affecting nearby tissues, or metastatic, spreading to distant organs like the bones or lungs. At this stage, treatment focuses on slowing the cancer and improving quality of life through hormone therapy, chemotherapy, targeted drugs, or immunotherapy. Clinical trials often test next-generation hormone treatments, PSMA-targeted radiotherapies, cancer vaccines, and precision therapies for men with advanced disease.

Ivermectin is an FDA-approved medication originally developed to treat parasitic infections such as river blindness, scabies, and intestinal worms. It’s been safely used for decades in both humans and animals.

In recent years, laboratory studies (mainly in cell lines and animal models) have suggested that ivermectin might have anti-cancer properties — including the ability to slow cell growth, interfere with cancer signaling pathways, and make tumor cells more sensitive to other treatments. Because of these early findings, researchers have begun exploring ivermectin as a potential repurposed drug for various cancers, including prostate cancer.

However, as of now, ivermectin is not an approved treatment for prostate cancer, and evidence in humans is still very limited. A few early-phase or preclinical studies in the U.S. and abroad are investigating its possible role, often in combination with standard therapies, but there are no large-scale clinical trials proving its safety or effectiveness for prostate cancer yet.

In short: ivermectin shows theoretical promise in lab settings, but its use in prostate cancer remains experimental, and it should only be taken as part of a properly monitored clinical study, not on its own.

Metastatic prostate cancer means the disease has spread outside the prostate gland to other parts of the body, most often the bones, lymph nodes, liver, or lungs. This happens when cancer cells break away from the original tumor and travel through the bloodstream or lymphatic system to form new tumors elsewhere.

It’s considered stage IV prostate cancer, and while it isn’t usually curable, it can often be managed for many years with treatments that slow growth and control symptoms. Common approaches include hormone therapy, chemotherapy, targeted therapy, radiation, and newer immunotherapies.

There are many ongoing clinical trials in the U.S. for metastatic prostate cancer. These studies are testing next-generation hormone therapies, radioligand treatments, genetic-targeted drugs, and cancer vaccines aimed at extending survival and improving quality of life for men living with advanced disease.

Stage 4 prostate cancer means the cancer has spread beyond the prostate gland to other parts of the body, such as the bones, lymph nodes, liver, or lungs. It’s the most advanced stage of the disease and is also called metastatic prostate cancer. At this point, the focus of treatment is usually on controlling the cancer, slowing its growth, relieving symptoms, and maintaining quality of life rather than curing it outright.

Treatment options may include hormone therapy (androgen deprivation therapy), chemotherapy, radiation, targeted therapies, and immunotherapy—often used in combination depending on the patient’s age, health, and genetic profile.

There are many clinical trials in the U.S. for stage 4 (metastatic) prostate cancer, testing new hormonal drugs, radiopharmaceuticals, vaccines, and precision therapies for men whose disease has spread or become resistant to standard treatments. These trials are helping researchers find more effective and personalized options for advanced prostate cancer.

The Prostate Cancer Clinical Trials Consortium (PCCTC) is a national research network dedicated to accelerating the development of new treatments for prostate cancer. Founded in 2006 with support from the U.S. Department of Defense and the Prostate Cancer Foundation, it brings together leading academic cancer centers across the country to design and run early-phase clinical trials.

The consortium focuses on testing innovative therapies—including targeted drugs, immunotherapies, radioligand treatments, and combination approaches—for men with all stages of prostate cancer, from localized to advanced disease. By coordinating research across multiple top institutions, the PCCTC helps speed up patient enrollment, standardize protocols, and share data, ultimately getting promising treatments to patients faster.
