Question 1

What is Relugolix?

Accepted Answer

Relugolix belongs to a class of medications known as gonadotropin-releasing hormone (GnRH) receptor antagonists . It functions by blocking specific receptors in the pituitary gland to prevent the release of hormones that normally stimulate the production of sex hormones.

By inhibiting this process, the medication lowers the levels of testosterone or estrogen and progesterone circulating in the body. This reduction in hormone levels is the primary way the medication achieves its therapeutic effect.

Question 2

What is Relugolix used for?

Accepted Answer

Relugolix is used to treat advanced prostate cancer .

Question 3

How does Relugolix work?

Accepted Answer

Relugolix belongs to a class of medications known as gonadotropin-releasing hormone (GnRH) receptor antagonists. It works by attaching to and blocking GnRH receptors in the pituitary gland, which is located at the base of the brain.

By blocking these receptors, the medication prevents the pituitary gland from signaling the body to produce other hormones, specifically luteinizing hormone (LH) and follicle-stimulating hormone (FSH). The reduction of these hormones has different effects depending on the condition being treated:

Prostate Cancer: In men, the drop in LH and FSH levels causes the testicles to stop making testosterone. Because many prostate cancer cells need testosterone to grow and spread, lowering these levels can help slow the progression of the disease.

Uterine Fibroids and Endometriosis: In women, the decrease in LH and FSH leads to lower levels of estrogen and progesterone produced by the ovaries. Reducing these hormones can help shrink uterine fibroids, reduce heavy menstrual bleeding, and manage pain associated with endometriosis.

Question 8

What is the dosage of Relugolix and how do I take it?

Accepted Answer

How to Take Relugolix

Relugolix is available as a tablet to be taken by mouth. It is generally taken once a day. To help you remember your medication, try to take it at the same time every day.

When taking this medication, follow these guidelines:

Administration: Swallow the tablets whole. Do not crush, chew, or break them.

Food: You may take the medication with or without food.

Initial Dose: If you are taking relugolix for prostate cancer, your healthcare provider will likely direct you to take a larger number of tablets on the first day of treatment, followed by a single dose once daily thereafter.

Missed Dose

If you miss a dose of relugolix, take it as soon as you remember on the same day. If you do not remember until the next day, skip the missed dose and continue with your regular schedule. Do not take two doses at the same time to make up for a missed one.

Question 9

Is Relugolix safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy Considerations

Relugolix can cause harm to a developing fetus and may result in pregnancy loss. It is not recommended for use during pregnancy. Healthcare providers typically require a pregnancy test for individuals of reproductive potential before starting the medication to ensure they are not pregnant.

Because relugolix may reduce the effectiveness of hormonal contraceptives, non-hormonal birth control methods (such as condoms or a diaphragm with spermicide) should be used during treatment. This should continue for at least 1 week after the last dose of relugolix. If pregnancy occurs during treatment, a doctor should be notified immediately.

Breastfeeding Considerations

There is no data on the presence of relugolix in human milk or its effects on milk production. Because of the risk of serious adverse reactions in a nursing child, breastfeeding is generally not recommended while taking this medication and for 1 week following the last dose.

Fertility

Animal studies suggest that relugolix may impair fertility in both males and females. It is not known if these effects on fertility are permanent or if they reverse after the medication is discontinued.

Question 11

What is the FDA approval status of Relugolix?

Accepted Answer

FDA Approval History

Relugolix was first approved by the U.S. Food and Drug Administration (FDA) in December 2020. It was the first oral gonadotropin-releasing hormone (GnRH) receptor antagonist approved for the treatment of adult patients with advanced prostate cancer.

In addition to its use in prostate cancer, the FDA has approved a combination tablet containing relugolix, estradiol, and norethindrone acetate for the following indications:

Uterine Fibroids: Approved in May 2021 to manage heavy menstrual bleeding associated with uterine fibroids in premenopausal women.

Endometriosis: Approved in August 2022 for the management of moderate to severe pain associated with endometriosis in premenopausal women.

Boxed Warning and Safety Information

The combination product containing relugolix, estradiol, and norethindrone acetate carries a Boxed Warning from the FDA. This warning highlights the increased risk of thromboembolic disorders and vascular events, such as blood clots, heart attack, or stroke. This risk is significantly higher in women over 35 who smoke.

The standalone relugolix product used for prostate cancer does not have a Boxed Warning, but regulatory labeling includes warnings regarding the risk of heart rhythm changes ( QT prolongation ) and potential harm to a developing fetus.
