Use of prednisone with abiraterone acetate in metastatic castration-resistant prostate cancer
-
Prostate cancer is a hormonally sensitive disease that can often be controlled for long periods with androgen-deprivation therapy ADT. When prostate cancer stops responding to this treatment, it is referred to as HRPC. Metastatic HRPC is a challenging form of the disease to treat because the cancer has spread to distant sites in the body and does not respond to treatment with standard hormonal therapy. Patients have been followed approximately 4 years from treatment and the overall survival is The study also found that Zytiga delayed the time to opiate use for cancer-related pain by 10 months Reference: 1.

Abstract Abiraterone acetate, a prodrug of the CYP17A1 inhibitor abiraterone that blocks androgen biosynthesis, is approved for treatment of patients with metastatic castration-resistant prostate cancer mCRPC in combination with prednisone or prednisolone 5 mg twice daily.
Publication types Research Support, Non-U. Gov't Review. Zytiga is also taken with other hormone therapy called androgen deprivation therapy ADT , which further reduces male hormone levels. Examples of ADT options include:. An alternative to ADT medication is bilateral orchiectomy surgical removal of the testicles , which also lowers testosterone levels.
Zytiga may be used off-label for other uses. But the American Urological Association recommends Zytiga as an option for people if all of the following apply:.
But people with nonmetastatic prostate cancer did go longer without having a significant change in cancer growth or needing to change therapy.
There are other drugs available that can treat your condition. Some may be better suited for you than others. You may wonder how Zytiga compares to other medications that are prescribed for similar uses. Here we look at how Zytiga and Xtandi are alike and different.
Both drugs decrease the activity of male hormones but work in slightly different ways. Zytiga blocks the production of certain male hormones. Xtandi helps prevent male hormones from attaching to their receptors proteins on prostate cancer cells. In both cases, the drugs help stop the spread of prostate cancer. Castration-resistant cancer continues to spread despite the use of drugs that lower male hormone levels. Metastatic prostate cancer has spread from the prostate to other areas in the body.
CSPC still responds to hormone therapy. Nonmetastatic prostate cancer has not spread to other parts of the body yet. Both drugs are taken along with other hormone therapy or following surgery to remove your testicles. This helps further reduce the effects of androgens male hormones such as testosterone on cancer cells. The usual dosage is 1, mg once a day.
You should take Zytiga without food on an empty stomach. You take Zytiga along with prednisone, a corticosteroid that helps reduce certain side effects. Xtandi comes as a mg capsule. The usual dosage is mg once a day.
You can take it with or without food. You may also need a lower dose of Zytiga if you have liver disease. Zytiga and Xtandi work in slightly different ways, so they have some similar and some different side effects. Below are examples of these side effects. These lists contain examples of more common side effects that can occur with Zytiga, Xtandi, or with both drugs when taken individually.
These lists contain examples of serious side effects that can occur with Zytiga, Xtandi, or with both drugs when taken individually. Zytiga and Xtandi are both brand-name drugs. Brand-name medications usually cost more than generics.
The brand-name form of Zytiga generally costs less than Xtandi. The actual price you pay will depend on your insurance plan, your location, and the pharmacy you use. Below are comparisons between Zytiga and several medications. Both drugs decrease the activity of male hormones, but they work in different ways. Zytiga prevents the production of certain male hormones. Casodex blocks male hormones from attaching to their receptors proteins on prostate cancer cells.
Both actions help stop the spread of prostate cancer. Both Zytiga and Casodex are used to treat metastatic prostate cancer. Metastatic prostate cancer has spread from the prostate to other areas of the body. Metastatic CRPC continues to grow despite the use of drugs that lower male hormone levels.
Zytiga is also approved to treat metastatic high-risk castration-sensitive prostate cancer. This type of prostate cancer still responds to drugs that lower male hormone levels. Casodex is FDA-approved to treat stage D2 metastatic prostate cancer. Stage D2 prostate cancer has metastasized spread to more distant bones, like the spine or ribs. Zytiga comes in two strengths: a mg tablet and a mg tablet. You should take the drug without food on an empty stomach.
You take Zytiga with prednisone a corticosteroid to reduce certain side effects. Both drugs must be taken with either additional hormone therapy or after surgery to remove your testicles. This helps further reduce the effects of androgens male hormones such as testosterone on prostate cancer cells. Zytiga and Casodex work in different ways in the body. Therefore, they have some similar and some different common and serious side effects.
These lists contain examples of more common side effects that can occur with Zytiga, Casodex, or with both drugs when taken individually. These lists contain examples of serious side effects that can occur with Zytiga, Casodex, or with both drugs when taken individually. Zytiga and Casodex are both brand-name drugs. There are generic forms of both Zytiga and Casodex. Brand-name Zytiga and generic Zytiga generally cost more than either form of Casodex.
The actual cost you pay for the drug will depend on your insurance plan, your location, and the pharmacy you use. Zytiga and Yonsa contain the same drug: abiraterone acetate. But Yonsa was created as a much smaller particle of abiraterone acetate so your bloodstream can better absorb the drug.
You can take Yonsa with or without food because of its smaller particle size. Metastatic CRPC continues to grow despite therapy that lowers male hormone levels. CSPC still responds to drug therapy that lowers male hormone levels. You take the drug with prednisone a corticosteroid to reduce certain side effects.
Yonsa comes as a mg tablet. The usual dosage is mg of Yonsa once a day. You take Yonsa with methylprednisolone a corticosteroid to reduce certain side effects.
This helps further reduce the effects that androgens male hormones such as testosterone have on cancer cells. Zytiga and Yonsa are two versions of the same drug. Yonsa was created as a much smaller particle of abiraterone acetate so your bloodstream can better absorb the drug. But you can expect the two drugs to have very similar effects on the body.
Zytiga and Yonsa are both brand-name drugs. There are currently no generic forms of Yonsa, but there is a generic form of Zytiga available. Brand-name Zytiga and generic Zytiga generally cost more than Yonsa. You take Zytiga with another drug called prednisone.
Prednisone is a prescription corticosteroid medication. Zytiga prevents your adrenal glands which make and release hormones from making cortisol. Cortisol is a hormone that plays a role in many important bodily functions. Some of these include maintaining blood pressure, regulating sleep-wake cycles, and controlling blood sugar levels.
Prednisone helps replace low cortisol levels, so it keeps these important bodily functions working properly. Prednisone also helps you avoid the side effects of low cortisol levels. If you have metastatic castration-resistant prostate cancer, you will take 5 mg of prednisone twice a day. If you have metastatic high-risk castration-sensitive prostate cancer, you will take 5 mg of prednisone once a day. You typically take Zytiga with prednisone and another hormone therapy drug.
This second type of hormone therapy is referred to as androgen deprivation therapy ADT. ADT medications help prevent the testicles from making male hormones that encourage prostate cancer to grow. The adrenal glands and prostate cancer cells themselves also make male hormones in small amounts. Zytiga helps prevent these secondary areas of the body from producing testosterone.
But Zytiga has caused liver toxicity dangerous levels of the drug that build up in the liver in some people. Drinking too much alcohol may increase the risk of liver damage in people who are taking Zytiga. Zytiga can interact with several other medications. It can also interact with certain supplements and foods.
Different interactions can cause different effects. For instance, some interactions can affect how well a drug works, while others can increase the number of side effects or make them more severe.
Below is a list of medications that can interact with Zytiga. This list does not contain all drugs that may interact with Zytiga. Before taking Zytiga, talk with your doctor and pharmacist. Tell them about all prescription, over-the-counter, and other drugs you take. Also tell them about any vitamins, herbs, and supplements you use.
Sharing this information can help you avoid potential interactions. If you have questions about drug interactions that may affect you, ask your doctor or pharmacist. In a clinical study , people who took Zytiga with Xofigo had a greater risk for bone fractures and death.
If you have questions about Xofigo, talk with your doctor. Provenge is a type of vaccine that makes your immune system more active in fighting prostate cancer. An immune system response shows that Provenge is working. The results of this study were similar in people who took Zytiga with Provenge and in people who used Zytiga after taking Provenge.
Instead, the guidelines recommended taking one drug or the other as a possible treatment. Taking Zytiga with certain seizure medications can increase how quickly your body gets rid of Zytiga. This can lower the amount of Zytiga in your body and make the drug less effective not work as well.
Examples of these seizure medications include:. In some instances, your doctor may want you to take Zytiga with one of these seizure medications. Taking Zytiga with certain tuberculosis medications can increase how quickly your body gets rid of Zytiga. This may make Zytiga less effective not work as well by lowering the amount of the drug in your body. Examples of these tuberculosis medications include:. Abiraterone acetate plus prednisone should be considered as the first treatment choice for patients with newly diagnosed metastatic castration-resistant prostate cancer if fatigue is a concern.
Abiraterone acetate Zytiga plus prednisone should be considered as the first treatment choice for patients with newly diagnosed metastatic castration-resistant prostate cancer mCRPC if fatigue is a concern. Results showed that abiraterone plus prednisone was associated with the highest increase in quality of life QoL , while enzalutamide was associated with the highest incidence of increased fatigue in patients, according to Klara Kvorning Ternov, a clinical assistant in the Department of Urology at Herlev and Gentofte Hospital in Herlev, Denmark.
However, abiraterone plus prednisone was associated with higher increases in weight, body mass index, visceral fat, and glycated hemoglobin, as well as the highest incidence of type 2 diabetes, Ternov said. Additionally, enzalutamide was associated with negative changes in cholesterol, including higher increases in low-density lipoprotein LDL cholesterol, and lower increases in high-density lipoprotein HDL cholesterol.
Abiraterone acetate, a prodrug of the CYP17A1 inhibitor abiraterone that blocks androgen biosynthesis, is approved for treatment of patients with metastatic castration-resistant prostate cancer mCRPC in combination with prednisone or prednisolone 5 mg twice daily.
This review evaluates the basis for the effects of prednisone on mineralocorticoid-related adverse events that arise because of CYP17A1 inhibition with abiraterone. Coadministration with the recommended dose of glucocorticoid compensates for abiraterone-induced reductions in serum cortisol and blocks the compensatory increase in adrenocorticotropic hormone seen with abiraterone.
Consequently, 5 mg prednisone twice daily serves as a glucocorticoid replacement therapy when coadministered with abiraterone acetate, analogous to use of glucocorticoid replacement therapy for certain endocrine disorders. We searched PubMed to identify safety concerns regarding glucocorticoid use, placing a focus on longitudinal studies in autoimmune and inflammatory diseases and cancer. Although glucocorticoids are often used to manage tumor-related symptoms or to prevent treatment-related toxicity, available evidence suggests that prednisone and dexamethasone might also offer modest therapeutic benefit in mCRPC.
Given recent improvements in survival achieved for mCRPC with novel agents in combination with prednisone, the risks of these recommended glucocorticoid doses must be balanced with the benefits shown for these regimens.

Abiraterone acetate in combination with prednisone or prednisolone at a low dose of 5 mg twice daily has been shown to improve survival of mCRPC patients. Abiraterone acetate, a prodrug of the CYP17A1 inhibitor abiraterone that blocks androgen biosynthesis, is approved for treatment of patients. ZYTIGA® (abiraterone acetate) is a prescription medicine that is used along with prednisone. ZYTIGA® is used to treat men with prostate cancer that has spread. Zytiga (abiraterone acetate) is taken with oral prednisone to help manage side effects that might occur with this treatment. Abiraterone acetate in combination with prednisone or prednisolone at a low dose of 5 mg twice daily has been shown to improve survival of mCRPC patients. Patients should also receive a GnRH analog concurrently or should have had bilateral orchiectomy. The drug should be taken on an empty stomach, either 1 hour before or 2 hours after a meal. Your doctor will check your potassium levels before you start Zytiga and at least once a month while you take the drug. Fatigue, quality-of-life and metabolic changes in men treated with enzalutamide versus abiraterone plus prednisone for metastatic castration-resistant prostate cancer HEAT : a randomised trial.Metastatic means the cancer has spread to other parts of the body. Both of these cancers are considered advanced. Testosterone usually plays a role in stimulating prostate cancer growth. Prostate cancer is considered castration-resistant if the cancer continues to grow or spread even with therapy or surgery to lower testosterone levels. High-risk castration-sensitive cancer still responds to lowered testosterone levels but requires more aggressive treatment.
Zytiga contains the drug abiraterone acetate. Reduced levels of male hormones, such as testosterone, help slow or stop the growth of prostate cancer cells. Zytiga comes as an oral tablet that you take once a day. In clinical studies of men with metastatic CRPC, taking Zytiga with prednisone in addition to standard hormone therapy prolonged life by about 4.
This means that they lived for three years after they started taking the drug. This was compared to standard therapy. Zytiga is a brand-name medication that contains abiraterone acetate. Zytiga comes as a mg tablet and a mg tablet.
A generic version of the mg tablet of abiraterone acetate is available. Zytiga can cause mild or serious side effects. The following list contains some of the key side effects that you may have while taking Zytiga. This list does not include all possible side effects. For more information on the possible side effects of Zytiga, talk with your doctor or pharmacist.
They can give you tips on how to deal with any side effects that may be bothersome. Most of these side effects may go away within a few days or a couple of weeks. Your doctor will monitor you for these side effects at regularly scheduled office visits. Call your doctor right away if you have serious side effects.
You may wonder how often certain side effects occur with this drug, or whether certain side effects pertain to it. Liver damage, severe liver toxicity when harmful levels of the drug build up in your liver , and liver failure were reported as side effects in clinical studies of Zytiga.
Liver damage typically occurs during the first three months after starting Zytiga. Six percent of people who took Zytiga in clinical trials had serious liver damage, based on liver function tests. Your doctor will test your liver function before you start taking Zytiga and during your treatment.
If these levels are too high, you may need to take a lower dose of Zytiga or stop treatment. If you have moderate liver damage before you begin taking Zytiga, your doctor will start you on a lower dose of Zytiga.
Symptoms of a UTI include feeling a burning sensation when you urinate, having to urinate often, and feeling that you have to urinate right away. If you have these symptoms, tell your doctor. You may need an antibiotic to help prevent the infection from spreading. Some people in clinical studies of Zytiga had side effects involving their kidneys, including:.
Some of these kidney effects may be related to a UTI, but they may not. If you have any of these symptoms, talk with your doctor about possible treatment options. But some people may lose weight because of some of the side effects of Zytiga, including diarrhea, nausea, vomiting, and upset stomach.
These side effects may prevent these people from eating on a regular schedule. These side effects may also prevent their bodies from taking in enough nutrients. Weight loss is commonly one of the first signs of cancer, according to the American Cancer Society.
During cancer treatment, people may lose weight for many reasons, including medication side effects, depression, and loss of appetite. Also, unexplained weight loss and muscle loss, called cachexia, is often seen during late-stage cancer due to poor food intake or poor food absorption.
Lastly, weight loss can be a symptom of liver damage or liver failure, which has been reported as a side effect in Zytiga clinical studies. They can help create a diet plan that provides all the vitamins, minerals, and calories you need. They can also refer you to a dietitian or nutritionist specially trained to help people with cancer.
As with all medications, the cost of Zytiga can vary. Your actual cost will depend on your insurance plan, your location, and the pharmacy you use. If you need financial support to pay for Zytiga, or if you need help understanding your insurance coverage, help is available.
Janssen Biotech, Inc. Typically, your doctor will start you on the usual dosage. Your doctor will ultimately prescribe the smallest dosage that provides the desired effect. The following information describes dosages that are commonly used or recommended. However, be sure to take the dosage your doctor prescribes for you.
Your doctor will determine the best dosage to suit your needs. The usual recommended dose for metastatic castration-resistant prostate cancer is 1, mg of Zytiga taken once a day. The dosage may be taken as two mg tablets or four mg tablets. With your Zytiga dose, you will also take 5 mg of prednisone by mouth twice a day.
The usual recommended dose for metastatic high-risk castration-sensitive prostate cancer is 1, mg of Zytiga taken once a day. This dosage may also be taken as two mg tablets or four mg tablets. With your Zytiga dose, you will also take 5 mg of prednisone by mouth once a day.
If you have moderately severe liver disease, the recommended dosage is mg of Zytiga taken once a day. If you miss a dose of Zytiga or prednisone, take a dose the next day at the regular time. Taking more than one dose of Zytiga or prednisone can increase your risk for side effects.
It depends. Your doctor may want you to continue your Zytiga treatment on a long-term basis if the drug is effective works well and safe for you.
Zytiga may also be used off-label for other conditions. Metastatic prostate cancer is cancer that has spread from the prostate to other areas in the body. For either type of cancer, Zytiga is used with prednisone, a corticosteroid that helps lessen certain side effects. Zytiga is also taken with other hormone therapy called androgen deprivation therapy ADT , which further reduces male hormone levels.
Examples of ADT options include:. An alternative to ADT medication is bilateral orchiectomy surgical removal of the testicles , which also lowers testosterone levels.
