Ofev

Conditions Treated

Ofev is primarily used to manage lung diseases that involve interstitial lung disease (ILD), which is a group of conditions that cause inflammation and scarring in the lungs. It is specifically approved for:

• Idiopathic Pulmonary Fibrosis (IPF): A condition where the lungs become scarred and stiff for unknown reasons, making it harder to breathe over time.
• Chronic Fibrosing Interstitial Lung Diseases with a Progressive Phenotype: This category includes various lung diseases where scarring continues to worsen and lung function declines despite other treatments.
• Systemic Sclerosis-Associated Interstitial Lung Disease (SSc-ILD): Lung scarring that develops in people with systemic sclerosis, also known as scleroderma.

Purpose of Treatment

The medication is used to slow the rate of decline in lung function in patients with these conditions. While it does not cure the underlying disease or reverse existing lung damage, it helps preserve the patient's ability to breathe by slowing the progression of new scarring.

Mechanism of Action

Ofev belongs to a class of medications known as kinase inhibitors. It works by interfering with the signaling processes that lead to the development of scar tissue in the lungs, a process called fibrosis.

In certain lung conditions, the body produces excess growth factors that signal cells to produce collagen and other materials that form scar tissue. Ofev blocks the activity of several tyrosine kinases, which are enzymes that act as messengers for these growth factors. Specifically, it targets:

• Platelet-derived growth factor receptors (PDGFR)
• Fibroblast growth factor receptors (FGFR)
• Vascular endothelial growth factor receptors (VEGFR)

By blocking these pathways, Ofev helps to slow down the thickening and scarring of lung tissue. This action helps to preserve lung function over time and reduces the rate of decline in how much air the lungs can hold. It is important to note that while Ofev can slow the progression of lung disease, it does not reverse existing scarring or cure the condition.

Common Side Effects

The most frequently reported side effects of Ofev involve the digestive system. These may include:

• Diarrhea
• Nausea and vomiting
• Stomach area pain
• Loss of appetite
• Weight loss
• Headache
• High blood pressure

Diarrhea is a very common side effect and can lead to dehydration. It is important to drink plenty of fluids and notify a healthcare provider if diarrhea occurs, as they may recommend specific treatments or a change in dosage.

Serious Side Effects

While less common, Ofev can cause serious health problems that require medical attention. These include:

• Liver problems: Symptoms may include yellowing of the skin or the whites of the eyes (jaundice), dark or tea-colored urine, pain on the right side of the stomach, or feeling very tired.
• Heart attack or stroke: Seek emergency help for chest pain or pressure, pain in the arms, back, neck or jaw, sudden numbness or weakness on one side of the body, or sudden vision changes.
• Gastrointestinal perforation: This is a tear in the wall of the stomach or intestines. Symptoms include severe stomach pain, swelling, or tenderness.
• Bleeding problems: Ofev may increase the risk of serious bleeding or bruising.
• Kidney issues: Changes in urination or swelling in the legs and feet may indicate kidney stress.

Patients should contact their doctor immediately if they experience signs of an allergic reaction, such as hives, difficulty breathing, or swelling of the face and throat.

Liver Toxicity

Ofev may cause serious liver injury. Healthcare providers usually monitor liver function through blood tests before starting the drug and periodically during treatment. Symptoms of liver problems include yellowing of the skin or eyes, dark urine, and pain in the upper right side of the abdomen.

Pregnancy and Birth Defects

This medication can cause fetal harm or pregnancy loss. It is essential to confirm a negative pregnancy test before beginning treatment. Effective contraception should be used during treatment and for at least three months after the final dose.

Gastrointestinal Risks

Severe diarrhea, nausea, and vomiting are common and may require medical management. There is also a risk of gastrointestinal perforation, which is a tear in the stomach or intestinal wall. People with a history of abdominal surgery or certain bowel conditions may be at higher risk.

Heart and Blood Clot Risks

Treatment with Ofev may increase the risk of heart attack, stroke, or blood clots. Immediate medical attention is necessary for symptoms like chest pain, sudden numbness, or trouble breathing.

Bleeding and Wound Healing

Ofev can increase the risk of bleeding episodes. It may also slow down the healing of wounds. Healthcare providers may recommend stopping the medication temporarily before and after surgery.

Pregnancy

Ofev (nintedanib) can cause fetal harm, including birth defects or the loss of a pregnancy. Healthcare providers typically require a pregnancy test before starting treatment to confirm that a patient is not pregnant. If a patient becomes pregnant or thinks they might be pregnant while taking this medication, they should contact their healthcare provider immediately.

Contraception

Patients who can become pregnant must use highly effective birth control during treatment and for at least 3 months after the last dose. Because Ofev can cause side effects such as severe diarrhea and vomiting, the effectiveness of oral birth control pills may be reduced. It is important to discuss reliable contraceptive options or backup methods with a healthcare professional.

Breastfeeding

It is not known if Ofev passes into human breast milk or how it might affect a nursing infant. Due to the potential for serious adverse reactions in a child, breastfeeding is not recommended while taking this medication.

Available Forms

Ofev is supplied as a soft-gelatin capsule for oral administration. These capsules are intended to be swallowed whole with food and water.

The capsules are available in different colors to distinguish between the available options:

• Peach-colored, opaque capsules
• Brown-colored, opaque capsules

FDA Approval and Indications

The U.S. Food and Drug Administration (FDA) has approved Ofev (nintedanib) for the treatment of the following conditions:

• Idiopathic pulmonary fibrosis (IPF).
• Chronic fibrosing interstitial lung diseases (ILDs) with a progressive phenotype.
• Systemic sclerosis-associated interstitial lung disease (SSc-ILD).

Safety Monitoring and Regulatory Actions

Ofev was first approved by the FDA in 2014. Since its release, the FDA has monitored its safety through the Adverse Event Reporting System (FAERS). In 2017, the FDA identified a potential signal of serious risk regarding drug-induced liver injury. Following an evaluation, the FDA updated the medication's labeling to include specific warnings about liver toxicity and requirements for liver enzyme monitoring.

Prescription Status

Ofev is available only with a prescription from a healthcare provider. It is not currently subject to a Risk Evaluation and Mitigation Strategy (REMS) program, but patients are monitored for side effects such as liver dysfunction and gastrointestinal issues as part of standard clinical care.

Factors Influencing Cost

The price you pay for Ofev depends on several factors, including your insurance plan's formulary, your copay or coinsurance requirements, and whether you have reached your deductible. Because Ofev is a specialty medication, it is typically dispensed through specialty pharmacies rather than standard retail pharmacies.

Generic Availability

A generic version of nintedanib, the active ingredient in Ofev, has been approved by the FDA. Generic medications generally cost less than brand-name versions. However, the availability of the generic version may vary depending on patent status and pharmacy supply.

Financial Assistance and Support

The manufacturer of Ofev and various third-party organizations may offer programs to help reduce out-of-pocket expenses for eligible patients. These options may include:

• Copay Cards: These are often available for patients with commercial insurance to help lower monthly costs.
• Patient Assistance Programs: These programs may provide the medication at a reduced cost or for free to individuals who meet specific income criteria and lack adequate insurance coverage.

Patients should consult with their healthcare provider, insurance company, or a specialty pharmacist to understand their specific coverage and explore available cost-saving options.
