What is advanced prostate cancer?

Advanced prostate cancer is cancer that has spread outside the prostate gland to nearby tissues, lymph nodes, bones, or other parts of the body. It may also be referred to as “stage IV” or “metastatic” prostate cancer. Some men who first receive a diagnosis for prostate cancer may have advanced prostate cancer. In others, they may develop advanced prostate cancer after they were diagnosed and treated for primary prostate cancer (cancer that is only in the prostate gland).

Cancer spreads to other parts of the body when cancer cells break away from the original tumor and enter the blood stream or lymphatic system. This allows them to travel to other parts of the body. Wherever these cells spread and form a tumor, that tumor is made of the same cancerous cells as the original tumor in the prostate gland. So it is the same cancer. For example, tumors that have spread to your bone are metastatic prostate cancer cells, not bone cancer.

Metastatic prostate cancer is not a curable condition. But treatment can help to control the cancer for long periods of time and relieve symptoms. Testosterone, a hormone produced in the testicles, can stimulate the growth of some prostate cancers. Hormone therapy may slow the growth of tumors by interfering with the body’s production of testosterone.

Here are answers to frequently asked questions about ZOLADEX therapy for advanced prostate cancer. These answers may help you better understand what ZOLADEX is, how it works, and what you may expect from your therapy.

ZOLADEX is a prescription medication that is approved for use in combination with flutamide (an antiandrogen) plus radiation therapy for locally advanced prostate cancer. Treatment with ZOLADEX in combination with flutamide should begin 8 weeks before starting radiation therapy and continue during radiation therapy.

ZOLADEX is also approved to lessen or relieve symptoms of advanced prostate cancer. In these clinically appropriate cases, ZOLADEX is used alone as long-term treatment.

Do not take ZOLADEX if you are sensitive to GnRH, GnRH hormone therapy drugs, or are allergic to any of the ingredients in ZOLADEX.

Please see Important Safety Information below.

ZOLADEX is a gonadotropin-releasing hormone agonist, or GnRH-A. It is an implant that is injected under the skin (subcutaneously). The implant gradually dissolves and releases the drug over the time between injections. There are two dosages of ZOLADEX: ZOLADEX 10.8 mg, which is injected once every 3 months, and ZOLADEX 3.6 mg, which is injected once a month. Your doctor will confirm which dosage is right for you.

Prostate cancer often relies on testosterone to grow. The majority of testosterone is produced by the testes. A GnRH-A, like ZOLADEX, is used to prevent testosterone production by the testes.

Testosterone, and testosterone-like chemicals that can be converted to testosterone, are produced by the adrenal glands even when ZOLADEX is being used. That is why ZOLADEX is sometimes used with an antiandrogen, like flutamide, which works to block the remaining testosterone. When a GnRH-A and an antiandrogen are used together, it is known as combined androgen blockade, or CAB therapy.

The most commonly reported side effects in men were related to a decrease in testosterone levels. Adverse effects that were reported in advanced prostate cancer clinical trials of ZOLADEX 3.6-mg implant were hot flashes, sexual dysfunction, decreased erections, lower urinary tract symptoms, lethargy, pain that worsened in the first 30 days of ZOLADEX use, swelling due to accumulation of fluid, upper respiratory infection, rash, and sweating. Among patients who received ZOLADEX 10.8-mg implant, the most commonly reported adverse effects were hot flashes, generalized pain, increased breast size (gynecomastia), pelvic pain, and bone pain.

In a prostate cancer (T2b-T4) clinical trial, ZOLADEX in combination with another drug, flutamide, was studied before and during radiation therapy. Side effects were similar in both groups. The most common side effects were hot flashes, diarrhea, nausea, and skin rash.

GnRH is an abbreviation for gonadotropin-releasing hormone. Both men and women have GnRH, which controls sex hormones. “A” stands for “agonist.” An agonist is a pharmaceutical compound that behaves in a similar way to a natural compound in the body. ZOLADEX is a GnRH agonist that mimics GnRH to help control testosterone hormones.

Elevated blood sugar and an increased risk of developing diabetes or worsening of blood sugar control in patients with diabetes have been reported in men who take ZOLADEX and drugs that work the same way as ZOLADEX. Your doctor will check your blood sugar levels and glycosylated hemoglobin (HbA1c), an indicator of long-term blood sugar control, as part of your treatment.

Increased risk of heart attack, sudden cardiac death, and stroke has been reported in men who have taken ZOLADEX and drugs that work the same way as ZOLADEX. Inform your doctor immediately if you develop any unusual symptoms.

ZOLADEX is injected by a doctor just under the skin (subcutaneously) in the lower abdominal area below the navel (belly button). The implant gradually dissolves and releases the drug over the time between injections.

ZOLADEX 3.6 mg is administered once a month (every 28 days).

For prostate cancer, ZOLADEX 10.8 mg may be administered every 3 months rather than once a month. You and your doctor can decide which dosage is right for you. Both are equally effective in reducing testosterone levels.

It is very important for you to get your injections as your doctor schedules to keep ZOLADEX levels consistently high enough to block testosterone production. Keep in mind that although a delay of a few days is permissible, every effort should be made to adhere to the dosing schedule your doctor has recommended.

If you need to be out of town when you are scheduled for a ZOLADEX injection, ask your doctor to help you arrange to receive your injection at a medical facility near where you will be staying. A few days late may be okay, but it’s important to stick to your overall injection schedule.

ZOLADEX is a type of long-acting medicine called an implant injection. When ZOLADEX is injected under the skin in your lower abdomen (below the belly button), the medicine is gradually released over the time until the next injection.

The difference between monthly ZOLADEX 3.6 mg and ZOLADEX 10.8 mg is that you will receive an injection every 3 months with ZOLADEX 10.8 mg rather than once a month. You and your doctor can decide which dosage is right for you. Both are equally effective in reducing testosterone levels.

Tumor flare is a temporary worsening of tumor-related symptoms, or an increase in bone pain that can occur soon after starting treatment with ZOLADEX. It is caused by temporary increases in testosterone levels. Your doctor will monitor your condition closely.

The combination of radiation with hormonal therapy can be effective in treating prostate cancer. Radiation can help shrink and kill prostate cancer cells, while hormonal therapy can help starve prostate cancer cells of the testosterone they need to grow. A hormonal injection/implant, like ZOLADEX, is used to reduce the testosterone produced by the testes. However, a small amount of testosterone, which is produced by the adrenal glands, may remain.

This is why, along with the ZOLADEX implant, your doctor may also prescribe another type of hormonal therapy, an oral antiandrogen such as flutamide. Antiandrogens do not prevent testosterone production. They work to block the remaining testosterone from reaching the cancer cells.
