Question 1

What is Wyost?

Accepted Answer

Wyost is a bone-modifying medication that belongs to a class of drugs known as RANK ligand inhibitors. It is a monoclonal antibody designed to target and bind to a specific protein in the body that regulates the activity of cells that break down bone.

By blocking this protein, the medication helps to slow the loss of bone and maintain bone density. This process is intended to prevent the excessive destruction of bone tissue.

Question 2

What is Wyost used for?

Accepted Answer

Wyost is used to treat osteoporosis .

Question 3

How does Wyost work?

Accepted Answer

Mechanism of Action

Wyost belongs to a class of medications known as RANK ligand (RANKL) inhibitors. It is a monoclonal antibody, which is a type of protein designed to recognize and attach to a specific structure in the body.

In the body, bone is constantly being broken down and rebuilt. Specialized cells called osteoclasts are responsible for breaking down bone tissue. To function, these osteoclasts require a protein called RANK ligand.

Wyost works by:

Binding to the RANK ligand protein.

Preventing the protein from activating its receptor on the surface of osteoclasts.

Reducing the formation, function, and survival of these bone-destroying cells.

By slowing down the process of bone breakdown, Wyost helps to keep bones stronger and decreases the likelihood of fractures or other bone complications associated with certain types of cancer.

Question 4

What are the active ingredients in Wyost?

Accepted Answer

The active ingredient in Wyost is denosumab .

Question 5

What are the side effects of Wyost?

Accepted Answer

Some people using Wyost may experience mild to moderate side effects. These often include:

Tiredness or weakness

Nausea

Diarrhea

Shortness of breath

Headache

Cough

Pain in the back, joints, or muscles

Wyost can cause serious side effects that may require medical intervention. Contact a healthcare provider immediately if you experience:

Low blood calcium (hypocalcemia): Symptoms include muscle spasms, twitches, cramps, or numbness and tingling in the hands, feet, or face.

Jaw bone problems (osteonecrosis): Signs include jaw pain, swelling, loose teeth, or slow healing of the gums after dental work.

Atypical thigh bone fractures: New or unusual pain in the hip, groin, or thigh area.

Serious infections: This may affect the skin, ears, or bladder. Symptoms include fever, chills, or skin that is red, swollen, or tender.

Skin reactions: Including dermatitis, rashes, or eczema.

Severe allergic reactions: Symptoms such as swelling of the face or throat, hives, and difficulty breathing.

Always consult with a healthcare professional about potential side effects.

Question 6

What drug class is Wyost?

Accepted Answer

Wyost belongs to the long-acting muscarinic antagonist drug class.

Question 7

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

Accepted Answer

Administration

Wyost is given as an injection just under the skin (subcutaneously). A healthcare professional usually administers the injection in a clinical setting, such as a doctor's office or hospital. Common injection sites include the upper arm, the upper thigh, or the stomach area (abdomen).

Frequency and Schedule

This medication is typically given at regular intervals, often every few weeks. Your healthcare provider will determine the exact schedule based on the condition being treated. It is important to receive every scheduled dose to ensure the medication works effectively.

Supplements

While receiving Wyost, your healthcare provider may instruct you to take daily calcium and vitamin D supplements to help maintain healthy mineral levels in your body.

Missed Dose

If you miss an appointment for your injection, contact your healthcare provider right away to reschedule. The medication should be administered as soon as possible, and your subsequent dosing schedule may be adjusted accordingly.

Question 8

Is Wyost safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

Wyost can cause harm to an unborn baby and is generally not recommended for use during pregnancy. Animal studies have shown that exposure to denosumab products during pregnancy can lead to an increased risk of fetal loss, stillbirth, and postnatal mortality. It may also interfere with the normal development of the fetus's immune system and bone growth.

If you are able to become pregnant, your healthcare provider may require a pregnancy test before you start treatment to ensure you are not pregnant. Effective contraception should be used during treatment and for at least 5 months after the last dose of Wyost. If you become pregnant while receiving this medication, notify your doctor immediately to discuss the potential risks.

Breastfeeding

It is currently unknown whether Wyost passes into human breast milk. Because many drugs are excreted in human milk and there is a potential for serious side effects in a nursing infant, a decision must be made whether to stop breastfeeding or stop the medication. You should discuss the risks and benefits with your healthcare provider to determine the best course of action based on your medical needs.

Question 9

What forms and strengths does Wyost come in?

Accepted Answer

Wyost is supplied as a sterile, preservative-free solution for injection. It is available in the following form:

Subcutaneous Injection: A liquid solution administered into the fatty tissue just beneath the skin, typically provided in a single-dose vial.

Question 10

What is the FDA approval status of Wyost?

Accepted Answer

FDA Approval and Biosimilar Status

Wyost (denosumab-bbdz) was approved by the U.S. Food and Drug Administration (FDA) in March 2024. It is the first interchangeable biosimilar to Xgeva (denosumab). As an interchangeable biosimilar, it has been shown to be highly similar to the reference product, with no clinically meaningful differences in safety or effectiveness. Depending on state laws, an interchangeable product may be substituted for the reference product by a pharmacist without requiring a new prescription from the healthcare provider.

Approved Indications

Wyost is indicated for several conditions related to bone health in patients with cancer:

Prevention of skeletal-related events in patients with multiple myeloma and in patients with bone metastases from solid tumors.

Treatment of adults and skeletally mature adolescents with giant cell tumor of bone that is unresectable or where surgical resection is likely to result in severe morbidity.

Treatment of hypercalcemia of malignancy refractory to bisphosphonate therapy.

Boxed Warning

The FDA-approved labeling for Wyost includes a Boxed Warning regarding the risk of severe hypocalcemia (critically low blood calcium levels) in patients with advanced chronic kidney disease, particularly those on dialysis. This condition can lead to serious complications, including hospitalization or death. Healthcare providers are required to evaluate patients for this risk and monitor calcium levels closely before and during treatment.

Question 11

What should I know about Wyost and withdrawal?

Accepted Answer

Risks of Discontinuation

When Wyost is stopped, its effects on bone metabolism reverse quickly. This can lead to a rapid increase in bone turnover and a subsequent loss of bone mineral density. In some cases, stopping the medication may increase the risk of bone fractures or other skeletal-related events that the drug was intended to prevent.

Severe Hypercalcemia

A significant risk associated with stopping denosumab products like Wyost is the development of severe hypercalcemia (high calcium levels in the blood). This is particularly a concern for patients with giant cell tumor of bone or those with growing skeletons. This rebound effect can occur weeks or months after the last dose is administered and may be severe enough to require hospitalization.

Symptoms of high calcium levels to watch for after stopping treatment include:

Nausea and vomiting

Constipation

Increased thirst and frequent urination

Muscle weakness

Confusion or fatigue

Managing Treatment Changes

Because of the risks associated with withdrawal, it is vital to adhere to the injection schedule prescribed by a healthcare provider. If treatment with Wyost must be interrupted or permanently stopped, doctors often transition the patient to a different type of bone-strengthening medication, such as a bisphosphonate, to help maintain bone density and prevent a surge in calcium levels.

Always consult your healthcare provider before missing a dose or stopping Wyost, as they must monitor your calcium levels and bone health closely during and after treatment.
