Zykadia

• Zykadia is a targeted therapy for metastatic non-small cell lung cancer (NSCLC).
• It specifically treats NSCLC that tests positive for an anaplastic lymphoma kinase (ALK) gene rearrangement.
• The medication works by inhibiting the ALK protein, which can drive cancer cell growth.
• Patients taking Zykadia must be monitored for potential side effects, including liver, heart, and lung issues.
• It is an oral medication, typically taken once daily.

What is Zykadia?

Zykadia refers to ceritinib, an oral prescription medication approved for the treatment of metastatic non-small cell lung cancer (NSCLC) that is anaplastic lymphoma kinase (ALK)-positive. This means the cancer cells have a specific genetic alteration involving the ALK gene, which can lead to uncontrolled cell growth. Zykadia is a type of targeted therapy, designed to specifically interfere with the molecules involved in cancer growth and progression, rather than broadly affecting all rapidly dividing cells like traditional chemotherapy.

The identification of ALK rearrangements in NSCLC has revolutionized treatment for a subset of patients, offering more personalized and often more effective therapeutic options. Zykadia is primarily used in patients whose cancer has spread to other parts of the body (metastatic) and has been confirmed to have this specific ALK gene alteration through diagnostic testing.

How Does Zykadia Treat Cancer?

Zykadia treats cancer by acting as an ALK inhibitor. In certain types of NSCLC, a gene fusion involving the ALK gene leads to the production of an abnormal ALK protein. This altered protein acts as a kinase, an enzyme that adds phosphate groups to other proteins, thereby signaling cancer cells to grow and divide uncontrollably. By inhibiting this abnormal ALK protein, Zykadia effectively blocks these growth signals, leading to a reduction in tumor size or slowing of cancer progression.

This targeted approach means that Zykadia is generally more specific in its action compared to conventional chemotherapy, which can affect both cancerous and healthy cells. It is particularly effective in patients whose tumors are driven by this ALK rearrangement. Clinical studies have shown that Zykadia can be effective as a first-line treatment for ALK-positive metastatic NSCLC, and also for patients whose disease has progressed after treatment with another ALK inhibitor, such as crizotinib.

Zykadia Uses, Side Effects, and Warnings

Zykadia is primarily used for the treatment of patients with metastatic ALK-positive NSCLC. It is indicated for patients who have not previously received treatment for their metastatic disease (first-line therapy) and for those whose disease has progressed on or who are intolerant to crizotinib, another ALK inhibitor. Understanding what is Zykadia used for involves recognizing its role in precision oncology, where treatment is tailored to the specific genetic characteristics of a patient’s tumor.

Like all medications, Zykadia can cause side effects. Patients should be aware of Zykadia side effects and warnings, which can range from common to severe. Common side effects often include diarrhea, nausea, vomiting, abdominal pain, fatigue, and elevated liver enzymes. More serious side effects can include:

• Severe liver problems
• Lung problems (interstitial lung disease/pneumonitis)
• Heart problems (e.g., slow heart rate, changes in electrical activity of the heart)
• Pancreatic problems (pancreatitis)
• High blood sugar (hyperglycemia)
• Vision problems

Due to these potential serious side effects, patients require regular monitoring, including blood tests to check liver function, pancreatic enzymes, and blood glucose levels, as well as electrocardiograms (ECGs) to monitor heart activity. It is crucial for patients to review the Zykadia patient information guide provided by their healthcare provider or pharmacist. This guide offers detailed instructions on proper administration, potential side effects, and important precautions, empowering patients to manage their treatment effectively and know when to seek medical attention. Zykadia can also cause harm to an unborn baby, so women of childbearing potential should use effective contraception during treatment and for a period after the last dose. Patients should also avoid grapefruit and grapefruit juice, as they can interact with the medication.
