Brukinsa, known scientifically as zanubrutinib, is a targeted therapy primarily used in the treatment of certain blood cancers, including mantle cell lymphoma (MCL) and chronic lymphocytic leukemia (CLL). Developed by BeiGene, is a BTK inhibitor that helps control cancer cell growth by interfering with specific protein pathways that aid in cancer progression. In this article, we’ll cover Brukinsa’s uses, benefits, potential side effects, and more.
What is Brukinsa?
(zanubrutinib) is an oral prescription medication classified as a Bruton’s tyrosine kinase (BTK) inhibitor. By inhibiting the BTK protein pathway, works to stop cancerous cells from growing and spreading in patients with certain blood cancers. It has been approved for use by the U.S. Food and Drug Administration (FDA) for specific conditions and continues to be studied for potential use in other blood disorders and malignancies.
Mechanism of Action
BTK is a protein involved in the signaling pathways that control the growth and survival of B-cells, a type of white blood cell. Brukinsa blocks this protein, helping to prevent the growth of B-cell malignancies. This targeted action makes Brukinsa highly effective in reducing tumor progression.
Primary Uses of Brukinsa
Brukinsa is primarily prescribed to treat:
- Mantle Cell Lymphoma (MCL)
MCL is a rare, aggressive form of non-Hodgkin lymphoma. is often used in patients who have tried other therapies but did not respond or for those who cannot tolerate traditional treatments. - Chronic Lymphocytic Leukemia (CLL)
In CLL, the most common type of leukemia in adults, is used to help slow down the disease’s progression by targeting specific B-cell proteins. - Waldenström’s Macroglobulinemia (WM)
WM is a rare type of lymphoma that produces high levels of abnormal proteins. helps reduce the production of these proteins and controls disease progression.
Key Benefits of Brukinsa
Brukinsa offers several advantages over traditional chemotherapy and other treatment methods:
- Targeted Treatment
By targeting BTK in B-cells, Brukinsa reduces the damage to healthy cells, which typically occurs with chemotherapy. - Convenient Oral Dosage
Unlike some treatments that require hospital stays or IV administration, is taken orally, allowing patients to maintain a more regular lifestyle. - Better Tolerability
Many patients experience fewer severe side effects with compared to conventional chemotherapy, which often leads to better quality of life. - Improved Response Rates
Clinical studies have shown that has a high response rate in treating MCL, CLL, and WM, making it a valuable treatment for patients who may have few options. - Long-Term Disease Control
For many patients, offers a more extended period of disease remission, especially for those who have already tried other treatments.
Potential Side Effects of Brukinsa
While is generally well-tolerated, it does come with some potential side effects. These can range from mild to severe and may differ based on the individual.
Common Side Effects
- Fatigue
Many patients report feeling tired, which can impact daily activities but often improves over time. - Diarrhea
Gastrointestinal discomfort is a frequent side effect, although it tends to be manageable. - Bruising and Bleeding
Due to its impact on blood cell production, Brukinsa may cause easy bruising and increase the risk of bleeding. - Muscle or Joint Pain
Some patients experience muscle or joint discomfort, which can be alleviated with mild pain relief if approved by a healthcare provider.
Serious Side Effects
- Infections
Brukinsa may increase the risk of bacterial, viral, and fungal infections. Patients should be vigilant about any signs of infection, such as fever or sore throat, and consult a healthcare provider immediately if symptoms arise. - Hematologic Toxicity
Brukinsa can lead to reductions in white blood cells, platelets, and hemoglobin, making regular blood tests necessary to monitor for potential complications. - Cardiovascular Issues
Heart conditions, including atrial fibrillation, have been reported in some patients. Those with preexisting heart issues should be carefully monitored. - Liver Toxicity
In rare cases, Brukinsa has been linked to elevated liver enzymes, which may indicate liver stress or damage. - Secondary Cancers
While rare, some patients on Brukinsa have developed secondary cancers, including skin cancer. Routine skin checks are recommended.
Important Considerations Before Starting Brukinsa
- Preexisting Conditions
Patients with heart disease, liver issues, or a history of infections should inform their doctor before starting Brukinsa. - Current Medications
Certain medications, including blood thinners, antifungals, and other cancer therapies, can interact with . It is crucial to discuss all medications with a healthcare provider. - Pregnancy and Breastfeeding
Brukinsa is not recommended for pregnant or breastfeeding women, as it may pose risks to the fetus or infant. - Regular Monitoring
Due to the risks of hematologic and liver toxicity, patients should undergo routine blood work to monitor white blood cells, liver enzymes, and overall organ function.
