Q: What is Gavreto used for?

Gavreto is used to treat: RET fusion-positive non-small cell lung cancer RET-mutant medullary thyroid cancer RET fusion-positive thyroid cancer

Q: How does Gavreto work?

Targeting RET Proteins Gavreto belongs to a class of medications known as kinase inhibitors. It specifically targets a protein called RET (Rearranged during Transfection). In certain types of cancer, such as non-small cell lung cancer and thyroid cancer, the RET gene may be fused with another gene or mutated. These genetic changes cause the RET protein to become overactive. An overactive RET protein acts like a switch that is stuck in the "on" position, sending constant signals to cells to divide and grow. This leads to the development and spread of cancerous tumors. How Gavreto Works Gavreto is designed to interfere with this signaling process through the following actions: Inhibition: The drug binds to the abnormal RET proteins, blocking their ability to send growth signals. Slowing Progression: By stopping these signals, Gavreto helps to slow or stop the growth of cancer cells. Selectivity: As a targeted therapy, it is specifically designed to act on cells with RET alterations, which may help limit damage to healthy cells that do not have these specific changes.

The active ingredient in Gavreto is pralsetinib .

Q: What are the side effects of Gavreto?

Common side effects of Gavreto may include: fatigue constipation diarrhea and others Always consult with a healthcare professional about potential side effects.

Q: What drug class is Gavreto?

Gavreto belongs to the RET kinase inhibitor drug class.

Q: What is the dosage of Gavreto and how do I take it?

How to Take Gavreto Gavreto is usually taken once daily. It is important to take this medication on an empty stomach. You should not eat for at least two hours before taking your dose and for at least one hour after taking it. Swallow the capsules whole with water. Do not crush, chew, or open the capsules. If you have trouble swallowing capsules, talk to your healthcare provider for guidance. Missed Doses and Vomiting If you miss a dose of Gavreto, 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 take your next dose at the regularly scheduled time. Do not take two doses at the same time to make up for a missed one. If you vomit after taking a dose, do not take an additional dose to replace it. Simply wait and take your next scheduled dose at the usual time.

Q: Is Gavreto safe during pregnancy and breastfeeding?

Pregnancy Gavreto can cause fetal harm when administered to a pregnant person. Based on its mechanism of action and findings from animal studies, the medication may lead to embryo-fetal toxicity or birth defects. Healthcare providers typically require a pregnancy test to ensure a patient is not pregnant before starting treatment. Effective contraception is recommended for patients of reproductive potential: Females: Use effective non-hormonal birth control during treatment and for at least 2 weeks after the final dose. Gavreto may reduce the effectiveness of hormonal contraceptives. Males: Those with female partners of reproductive potential should use effective contraception during treatment and for at least 1 week after the final dose. If you become pregnant or think you might be pregnant while taking this medication, contact your healthcare provider immediately to discuss the potential risks. Breastfeeding There is no information regarding the presence of Gavreto in human breast milk or its effects on a breastfed child. Because of the potential for serious adverse reactions in a nursing infant, breastfeeding is not recommended during treatment and for 1 week after the last dose.

Q: What is the FDA approval status of Gavreto?

FDA Approval Status Gavreto received its initial approval from the FDA in 2020. It is a kinase inhibitor targeted therapy. Several of its indications were approved under the FDA's accelerated approval pathway, which is used for drugs that treat serious conditions and fill an unmet medical need based on promising early data. Approved Indications Gavreto is currently FDA-approved for the treatment of adults and certain pediatric patients with the following conditions: Metastatic RET Fusion-Positive Non-Small Cell Lung Cancer (NSCLC): For adult patients whose cancer has spread to other parts of the body. RET-Mutant Medullary Thyroid Cancer (MTC): For adults and pediatric patients aged 12 years and older with advanced or metastatic disease who require systemic therapy. RET Fusion-Positive Thyroid Cancer: For adults and pediatric patients aged 12 years and older with advanced or metastatic disease who require systemic therapy and whose cancer did not respond to radioactive iodine treatment. Regulatory Requirements and Monitoring Because some uses were granted accelerated approval, the manufacturer may be required to conduct further clinical trials to confirm the drug's long-term clinical benefit. Continued approval for these specific indications may depend on the results of these confirmatory trials. There are currently no boxed warnings or Risk Evaluation and Mitigation Strategy (REMS) programs required for Gavreto. The FDA continues to monitor the safety and effectiveness of the medication through standard post-marketing surveillance and adverse event reporting systems.

Question 1

What is Gavreto?

Accepted Answer

Gavreto is a prescription medication known as a kinase inhibitor. It works by blocking the activity of specific proteins that signal cancer cells to multiply.

By targeting these proteins, the medication helps slow or stop the progression of cancer. This type of treatment is considered a targeted therapy because it focuses on specific genetic changes within the cells.

Question 2

What is Gavreto used for?

Accepted Answer

Gavreto is used to treat:

RET fusion-positive non-small cell lung cancer
RET-mutant medullary thyroid cancer
RET fusion-positive thyroid cancer

Question 11

What should I know about Gavreto and cost?

Accepted Answer

Insurance and Pharmacy Factors

The price you pay for Gavreto can vary based on your insurance plan. Most commercial insurance plans and Medicare Part D cover this medication, but it is often classified as a specialty drug. This classification may place it on a higher cost tier, which can result in a higher co-pay or coinsurance amount.

Gavreto is typically dispensed through specialty pharmacies. These pharmacies specialize in medications that require unique handling, storage, or monitoring. The cost may differ between these providers depending on their specific contracts with insurance companies.

Financial Assistance Programs

Because Gavreto is a brand-name specialty medication, the manufacturer often provides programs to help reduce the financial burden for patients. These may include:

Co-pay Savings Cards: These are often available to patients with commercial (private) insurance to help lower out-of-pocket costs.
Patient Assistance Programs: These programs may provide the medication at no cost or a significantly reduced cost for individuals who are uninsured or underinsured and meet certain income requirements.

Generic Availability

There is currently no generic version of Gavreto (pralsetinib) available. Generic drugs usually cost less than brand-name drugs, but because Gavreto is a newer targeted therapy, it remains available only as a brand-name product. The lack of generic competition contributes to its higher price point.
