Treatment Summary

Enzalutamide is a medication used to treat prostate cancer that does not respond to other treatments. It works by blocking androgen receptors, which stops hormones from stimulating tumor growth. Enzalutamide was approved by the FDA in 2012 under the brand name Xtandi.

How Enzalutamide Affects Patients

Enzalutamide is a drug designed to stop prostate cancer from progressing. It does this by blocking the hormones and hormone receptors that cause prostate cells to grow. After a few years, prostate cancer will start to become resistant to hormone deprivation treatment, but studies show that Enzalutamide can help to slow the growth of prostate cancer cells. Clinical trials suggest that Enzalutamide can reduce the risk of death in patients by 37% compared to those taking a placebo. The drug also reduces serum PSA levels for at least 12 weeks, although this effect may be short-lived.

How Enzalutamide works in the body

Enzalutamide is a drug that blocks the effects of testosterone and other male hormones on cancer cells. It prevents testosterone and other hormones from binding to the androgen receptor, a protein that tells the cancer cell to grow and spread. Enzalutamide is more effective at blocking hormones from binding to the receptor than some other drugs, and it has fewer side effects. It also works better than testosterone at preventing cancer cells from growing and spreading.

Enzalutamide Toxicity & Overdose Risk

In studies with mice, taking enzalutamide orally during pregnancy caused embryo-fetal death, resorptions, and changes in the distance between genitalia, as well as cleft palate and missing palatine bone when taken at the highest dose. Rats who were given a single oral dose of 30 mg/kg on the 14th day of gestation had a fetal concentration of enzalutamide that was about 0.3 times that found in the mother's plasma. Enzalutamide may also reduce fertility in males. The most common side effects reported in adults include fatigue, back pain, diarrhea, joint pain, fl

Enzalutamide for Metastatic Castration-Resistant Prostate Cancer

Really effective with only a few small side effects. The fatigue is the worst part, but it's worth it considering how well this works. It's also quite expensive though.

Enzalutamide for Metastatic Castration-Resistant Prostate Cancer

I didn't find this treatment very effective. My disease progressed and I developed new bony metastasis within the 3 months of taking it. It's well tolerated though, with the main side effects being hot flashes and constant nausea.

Patient Q&A Section about enzalutamide

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Is enzalutamide better than chemotherapy?

"In a study of men with metastatic prostate cancer who had not received chemotherapy, those who were treated with enzalutamide had a longer time until cancer progression or death, improved overall survival, and delayed the need for chemotherapy by a median of 17 months."

Answered by AI

Is enzalutamide a form of chemotherapy?

"Xtandi is not a chemotherapy drug. Although it is used to treat cancer, Xtandi is a type of hormone therapy that works by preventing prostate cancer cells from growing and spreading by blocking the action of a group of hormones called androgens."

Answered by AI

How effective is enzalutamide for prostate cancer?

"On average, men who were given enzalutamide lived about 29% longer than men who were given placebo."

Answered by AI

How long do you take enzalutamide for?

"Xtandi is typically taken until prostate cancer starts to progress or spread (metastasize). It can cause side effects or adverse events, so the patient may need to stop taking it at some point."

Answered by AI

What are the side effects of taking enzalutamide?

"If you're experiencing any of the following, you may be suffering from a lack of vitamin d: weakness, tiredness, joint pain, muscle weakness or stiffness, weight loss, loss of appetite, headache, and dizziness."

Lutetium-177-PSMA-617 for Prostate Cancer

18+
Male
Houston, TX

The purpose of this study is to evaluate the safety and tolerability of Lutetium-177-PSMA-617 (PLUVICTO) in patients with metastatic castration-resistant prostate cancer (mCRPC) and extensive bone metastases, which appear as a "super scan" pattern on a bone scan. Pluvicto is FDA-approved, but patients with super scan bone scans were previously excluded from the VISION clinical trial, leaving a knowledge gap. The study will enroll up to 30 men with metastatic castration-resistant prostate cancer, with an initial dosing approach that differs from the standard dose. The safety and tolerability of PLUVICTO will be evaluated in this study, with a focus on identifying the optimal dose for this population. This study addresses an important gap in understanding how Pluvicto performs in mCRPC patients with super scan findings.

177Lu-HTK03170 for Prostate Cancer

18+
Male
Vancouver, Canada

This study will determine the safe initial injected activity of the radioligand therapy 177Lu-HTK03170 for the measurement of dosimetry and initiation of treatment in subjects with PSMA-positive, metastatic castrate resistant prostate cancer, (mCRPC). Subjects will receive treatment which will be escalated between cycles and personalized based on dosimetry calculations and imaging. In addition, antitumour activity will be measured by radiographic response, and further assessments of the treatment will be measured by CT imaging, ctDNA/ctRNA, PSA, PSMA PET/CT, and quality of life questionnaires. Subjects will be followed for 2 years or until they have progression and are switched to another systemic treatment.

SABR for Prostate Cancer

18+
Male
Toronto, Canada

There is increasing worldwide interest in exploring stereotactic ablative body radiotherapy (SABR) for treating metastases in men with prostate cancer, including for the treatment of oligoprogressive metastases. The latter applies to a situation whereby patients with widespread metastases undergoing systemic therapy present with a solitary or a few metastatic tumors that progress, while all other metastases are stable or responding. The usual practice would be to change systemic therapy at this point, but another approach is to locally ablate the "rogue" metastases and continue the same systemic therapy. SABR used in this scenario may delay the need to switch to another line of systemic therapy and improve progression-free survival while patients stay on the same systemic therapy.
