Question 1

What is Gattex?

Accepted Answer

Gattex is a man-made form of a hormone called glucagon-like peptide-2 (GLP-2), which is naturally produced in the body. This hormone is responsible for maintaining the health and growth of the lining within the intestines.

By acting like this natural hormone, the medication helps the intestinal surface work more effectively. This process supports the body's ability to take in necessary fluids and nutrition through the digestive system.

Question 2

What is Gattex used for?

Accepted Answer

Gattex is used to treat short bowel syndrome .

Question 3

How does Gattex work?

Accepted Answer

Mechanism of Action

Gattex is a synthetic version of a hormone called glucagon-like peptide-2 (GLP-2). This hormone is naturally produced in the body and is responsible for maintaining the health and function of the intestinal lining.

In people with short bowel syndrome, the body often struggles to absorb enough fluids and nutrients because a significant portion of the small intestine is missing or damaged. Gattex helps the remaining part of the intestine work more effectively through several processes:

Increasing Surface Area: It helps grow the small, finger-like projections called villi that line the intestine, which increases the area available for absorption.

Improving Absorption: It enhances the body's ability to take in water, electrolytes, and nutrients from food and drinks.

Slowing Digestion: It slows down the movement of food through the digestive tract, providing more time for the intestine to absorb what is needed.

By improving the intestine's ability to absorb nutrients, Gattex may reduce the volume of parenteral nutrition (IV feeding) or fluids a person requires to stay healthy.

Question 7

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

Accepted Answer

How Gattex is Administered

Gattex is given as a subcutaneous injection, which means it is injected into the fatty tissue just under the skin. It is typically used once every day at approximately the same time.

Preparation and Use

This medication comes as a powder in a vial that must be mixed with a specific liquid (diluent) before it can be injected. Once the solution is prepared, it should be used immediately. Each vial is intended for a single use only; any remaining medication should be discarded after the dose is given.

Common injection sites include:

The stomach area (abdomen)

The thighs

The back of the upper arms

It is important to rotate the injection site each time you use the medication to help prevent skin irritation. Do not inject into skin that is red, bruised, or scarred.

Missed Doses

If you miss a dose, take it as soon as you remember on the same day. If you do not remember until the following day, skip the missed dose and return to your regular schedule. Do not take two doses on the same day to make up for a missed one.

Question 8

Is Gattex safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

There are no adequate and well-controlled studies of Gattex in pregnant women to determine if there is a drug-associated risk of major birth defects or miscarriage. Animal reproduction studies using doses significantly higher than the recommended human dose did not show evidence of harm to the developing fetus. However, because animal studies do not always predict human response, Gattex should be used during pregnancy only if the potential benefit justifies the potential risk.

If you are pregnant or planning to become pregnant, consult your healthcare provider to discuss your treatment options and the potential impact on the pregnancy.

Breastfeeding

It is not known whether Gattex passes into human breast milk or how it might affect a nursing infant or milk production. Because many drugs are excreted in human milk and there is a potential for serious adverse reactions in nursing infants, a decision should be made whether to discontinue breastfeeding or discontinue the drug.

Healthcare providers typically weigh the importance of the medication to the mother against the potential risks to the infant when making a recommendation. It is important to talk with your doctor about the best way to feed your baby while using this medication.

Question 9

What forms and strengths does Gattex come in?

Accepted Answer

Available Forms

Gattex is supplied as a sterile, preservative-free powder in a single-dose glass vial. It is administered by subcutaneous injection.

The medication is typically available in a kit that includes the following components for preparation and administration:

Vials containing the medication powder

Prefilled syringes containing sterile water for injection, which serves as the diluent

Disposable needles and syringes

Alcohol swabs

Before use, the powder is reconstituted with the provided liquid to form a solution. The resulting liquid should be clear and colorless to pale yellow, without any visible particles.

Question 10

What is the FDA approval status of Gattex?

Accepted Answer

FDA Approval History

The U.S. Food and Drug Administration (FDA) first approved Gattex in December 2012 for adults with short bowel syndrome who depend on parenteral support. In May 2019, the FDA expanded this approval to include pediatric patients aged 1 year and older.

Risk Evaluation and Mitigation Strategy (REMS)

Gattex is subject to a Risk Evaluation and Mitigation Strategy (REMS) program. This safety program is required by the FDA to ensure that the benefits of the drug outweigh the risks of potential side effects, specifically the risk of accelerated neoplastic growth (abnormal cell growth) and the development of colorectal polyps.

Generic Availability

Currently, there is no FDA-approved generic version of Gattex available in the United States. It is classified as an orphan drug, which is a status granted to medications intended for the treatment of rare diseases or conditions.

Question 11

What should I know about Gattex and cost?

Accepted Answer

Factors Influencing Cost

The price of Gattex varies significantly based on several factors, including the specific insurance plan, the pharmacy used, and the dosage required. Because it is a specialty medication, it is typically not available at standard retail pharmacies and must be ordered through a specialty pharmacy.

Insurance Coverage

Most private insurance plans and Medicare Part D provide coverage for Gattex, though it often falls into a high-cost specialty tier. This may result in significant out-of-pocket expenses, such as deductibles or coinsurance payments. Prior authorization from a healthcare provider is usually required before insurance will approve coverage.

Generic Availability

There is currently no generic version of Gattex (teduglutide) available in the United States. Brand-name specialty drugs generally remain expensive until a generic alternative is approved by the FDA and released to the market.

Financial Assistance

The manufacturer of Gattex may offer programs to help reduce the cost for eligible patients. These options often include:

Copay Assistance Cards: These can help patients with commercial insurance lower their out-of-pocket costs.

Patient Assistance Programs: These programs may provide the medication at no cost or a reduced cost for individuals who meet specific income requirements and lack adequate insurance coverage.
