Alunbrig, a potent tyrosine kinase inhibitor, is primarily utilized in the management of metastatic non-small cell lung cancer (NSCLC) characterized by anaplastic lymphoma kinase (ALK) gene rearrangements. 

Specifically designed for patients who have progressed on or are intolerant to crizotinib, Alunbrig offers a targeted therapy option. By selectively inhibiting ALK protein activity, Alunbrig disrupts cancer cell proliferation and survival pathways. 

This targeted mechanism has demonstrated efficacy in clinical trials, showcasing tumor shrinkage and disease control. Notably, Alunbrig’s safety profile is manageable, with adverse events typically reversible. Its indication spans from second-line therapy in those previously treated with ALK inhibitors to first-line treatment for those unsuitable for platinum-based chemotherapy. 

As a result, Alunbrig stands as a promising therapeutic choice, offering hope for improved outcomes and enhanced quality of life for patients with ALK-positive metastatic NSCLC.

Alunbrig operates by selectively inhibiting the activity of a protein called anaplastic lymphoma kinase (ALK). This protein plays a crucial role in promoting the growth and survival of cancer cells, particularly in non-small cell lung cancer (NSCLC) with ALK mutations. 

By blocking the function of ALK, Alunbrig disrupts the signaling pathways that drive the proliferation of cancer cells, ultimately impeding their ability to grow, divide, and spread. This mechanism of action helps to shrink tumors, alleviate symptoms, and potentially prolong survival in patients with ALK-positive NSCLC. 

Alunbrig is designed to specifically target cancer cells while sparing healthy cells, thereby minimizing adverse effects associated with traditional chemotherapy. By interfering with the molecular pathways involved in cancer progression, Alunbrig represents a targeted therapy approach that holds promise in the treatment of ALK-positive NSCLC.

Common Side Effects

• Nausea: Feeling queasy or experiencing an urge to vomit is a common side effect of Alunbrig.
• Diarrhea: Some patients may experience loose or watery stools while taking this medication.
• Fatigue: Feeling tired or lacking energy is a frequent complaint among individuals undergoing treatment with Alunbrig.
• Elevated Liver Enzymes: Alunbrig may cause an increase in liver enzyme levels, which can be detected through blood tests.

Serious Side Effects

• Interstitial Lung Disease: Rare but serious, interstitial lung disease can cause coughing, shortness of breath, and difficulty breathing.
• Bradycardia (Slow Heart Rate): Alunbrig may lead to a decrease in heart rate, which can manifest as dizziness, fatigue, or fainting.
• Vision Changes: Some patients may experience changes in vision, such as blurriness or difficulty focusing.
• Severe Skin Reactions: Rarely, Alunbrig can cause severe skin reactions, including rash, blistering, or peeling of the skin.

Precautions and warnings should be carefully considered before initiating treatment with Alunbrig. Regular monitoring of liver function tests is advised to detect any potential liver toxicity early on. 

Additionally, patients should be closely monitored for signs and symptoms of interstitial lung disease (ILD), such as persistent cough or difficulty breathing, as treatment with Alunbrig may exacerbate this condition. Cardiac monitoring is essential due to the risk of bradycardia (slow heart rate), particularly in patients with pre-existing cardiac conditions. 

Any changes in vision should be promptly reported to a healthcare provider, as Alunbrig may cause vision disturbances. It is crucial for women of reproductive potential to use effective contraception during treatment, as Alunbrig can cause fetal harm if used during pregnancy. 

Furthermore, caution should be exercised when administering Alunbrig to patients with pre-existing liver impairment, as dose adjustments may be necessary based on liver function tests. Overall, adherence to these precautions and warnings can help mitigate the risks associated with Alunbrig therapy and optimize patient safety and outcomes.

Alunbrig’s efficacy and safety may be influenced by concurrent use of certain medications, necessitating careful consideration of potential drug interactions. 

Strong CYP3A inhibitors, including drugs like ketoconazole and clarithromycin, can elevate Alunbrig’s plasma concentration, increasing the risk of adverse effects. Conversely, strong CYP3A inducers such as rifampin may reduce Alunbrig’s efficacy. 

Gastric acid-reducing agents like proton pump inhibitors (PPIs) can also affect Alunbrig absorption, necessitating separation of administration by several hours. Healthcare providers should be vigilant in assessing patients’ medication regimens and considering potential interactions to optimize Alunbrig’s therapeutic benefits while minimizing risks.

The recommended dosage of Alunbrig for the treatment of non-small cell lung cancer (NSCLC) is an initial oral dose of 180 mg once daily, taken with food to enhance absorption. 

Depending on the patient’s tolerability and individual factors, dose adjustments may be necessary, including temporary interruptions or reductions in case of adverse reactions. For patients with hepatic impairment, dosage adjustments are not typically required for mild or moderate impairment, but caution is advised in severe cases. 

When Alunbrig is co-administered with strong CYP3A inhibitors or inducers, dosage modifications may be needed to maintain therapeutic efficacy and minimize adverse effects. 

Additionally, to optimize absorption, Alunbrig administration should be separated from gastric acid-reducing agents by several hours. Monitoring of liver function tests and cardiac function is essential throughout treatment to ensure patient safety and assess for any potential adverse reactions or complications.

• Alunbrig is available only with a valid prescription from a healthcare provider.
• A healthcare professional, typically an oncologist or pulmonologist, will assess the patient’s medical history, diagnostic tests, and treatment needs before prescribing Alunbrig.
• The prescription requirement ensures that Alunbrig is used appropriately for its approved indications and that patients receive proper monitoring and guidance during treatment.
• Healthcare providers may also consider factors such as the patient’s overall health, medication history, and potential drug interactions before prescribing Alunbrig.
• Patients should follow their healthcare provider’s instructions carefully and report any concerns or side effects experienced during treatment.
