Why is this medication prescribed?

Futibatinib is a medication primarily prescribed for the treatment of advanced or metastatic solid tumors that have alterations in the fibroblast growth factor receptor 2 (FGFR2) gene. These tumors may include but are not limited to bile duct cancer (cholangiocarcinoma) and bladder cancer. FGFR2 alterations can lead to uncontrolled cell growth and cancer progression, and Futibatinib works by inhibiting the activity of FGFR2, thereby slowing down or stopping the growth of cancer cells.

How should this medicine be used?

The usage of Futibatinib typically involves oral administration, usually in the form of tablets. The specific dosage and frequency will be determined by a healthcare provider based on various factors such as the patient’s medical condition, response to treatment, and any other medications they may be taking. It’s essential to follow the instructions provided by the healthcare provider and the medication label carefully.

Here are general guidelines for using Futibatinib:

• Dosage: The dosage of Futibatinib can vary depending on factors such as body weight, overall health, and the type and stage of cancer being treated. The healthcare provider will determine the appropriate dosage for each individual patient.
• Administration: Futibatinib is typically taken orally, with or without food, as directed by the healthcare provider. It’s important to swallow the tablets whole with a glass of water, without crushing or chewing them.
• Schedule: Futibatinib is often taken once daily, but the exact dosing schedule may vary. Patients should adhere to the prescribed schedule and not alter the dosage or frequency without consulting their healthcare provider.
• Monitoring: During treatment with Futibatinib, regular monitoring by healthcare professionals is necessary to assess the patient’s response to the medication and to monitor for any potential side effects or complications.
• Adherence: It’s crucial for patients to take Futibatinib exactly as prescribed, even if they feel well. Missing doses or altering the dosage without medical guidance could affect the effectiveness of the treatment.
• Side effects: Patients should be aware of potential side effects associated with Futibatinib and report any unusual symptoms or adverse reactions to their healthcare provider promptly.

As with any prescription medication, it’s essential for patients to communicate openly with their healthcare providers regarding any concerns or questions about Futibatinib treatment.

Other uses for this medicine

Some of the ongoing or potential uses for Futibatinib beyond its current approved indications may include:

• Treatment of other cancers with FGFR genetic alterations, such as certain types of solid tumors like breast cancer, lung cancer, or glioblastoma.
• Exploration of its efficacy in combination therapies with other anticancer drugs or immunotherapies.
• Investigating Futibatinib in earlier stages of cancer or as adjuvant therapy after surgery in certain cancer types.

What special precautions should I follow?

Regarding special precautions for Futibatinib, here are some important considerations:

• Pregnancy and breastfeeding: Futibatinib may cause harm to a developing fetus, so it’s crucial to avoid pregnancy while taking this medication. Effective contraception should be used during treatment and for a period after discontinuing the medication, as advised by a healthcare provider. It’s also not recommended to breastfeed while taking Futibatinib.
• Liver function monitoring: Since Futibatinib can affect liver function, regular monitoring of liver function tests is necessary during treatment. Patients should promptly report any symptoms of liver problems, such as yellowing of the skin or eyes (jaundice), abdominal pain, nausea, vomiting, or unusual fatigue.
• Cardiac monitoring: Some patients may experience cardiac side effects while taking Futibatinib, including QT interval prolongation, which can increase the risk of arrhythmias (irregular heartbeats). Cardiac function should be monitored, especially in patients with pre-existing cardiac conditions or risk factors for QT prolongation.
• Blood pressure monitoring: Futibatinib may cause hypertension (high blood pressure) in some patients. Blood pressure should be monitored regularly during treatment, and antihypertensive medications may be required to manage elevated blood pressure.
• Interstitial lung disease (ILD): ILD, including pneumonitis, has been reported in patients receiving Futibatinib. Patients should be monitored for respiratory symptoms such as cough, dyspnea (difficulty breathing), or fever, and treatment should be discontinued if ILD is suspected.
• Drug interactions: Futibatinib may interact with other medications, including certain CYP3A4 inducers or inhibitors. Patients should inform their healthcare providers about all medications, supplements, or herbal products they are taking to avoid potential interactions.

Patients should always follow their healthcare provider’s instructions and report any concerns or adverse reactions while taking Futibatinib. Close monitoring and regular follow-up appointments are essential to ensure safe and effective treatment.

What special dietary instructions should I follow?

Regarding dietary instructions for Futibatinib, there are no specific dietary restrictions associated with this medication. However, it’s essential to maintain a balanced and healthy diet to support overall well-being during cancer treatment. Patients should discuss any dietary concerns with their healthcare provider or a registered dietitian.

What should I do if I forget a dose?

If a dose of Futibatinib is missed, the following steps should be taken:

• Take the missed dose as soon as remembered: If it’s within a few hours of the missed dose, take it as soon as remembered. If it’s close to the time for the next scheduled dose, skip the missed dose and continue with the regular dosing schedule.
• Do not double dose: Do not take a double dose to make up for the missed dose. Taking too much Futibatinib at once can increase the risk of side effects without providing additional benefit.
• Notify healthcare provider: If multiple doses are missed or if unsure about what to do, it’s essential to contact the healthcare provider or pharmacist for further guidance.

What side effects can this medication cause?

Futibatinib, like any medication, can cause side effects. Not everyone will experience these side effects, and their severity can vary from person to person.
