What is Alecensa?

Alecensa (alectinib) is an oral kinase inhibitor that may be used to treat certain types of non-small cell lung cancer (NSCLC) in adults that have been caused by an abnormal anaplastic lymphoma kinase (ALK) gene, specifically:

• to help prevent your lung cancer from coming back after your tumor has been removed by surgery (adjuvant), or
• as treatment when your lung cancer has spread to other parts of your body (metastatic).

Alecensa is used only if your cancer has a specific genetic marker (an abnormal “ALK” gene). Your doctor will test you for this gene.

Alecensa works by targeting ALK and RET — these are 2 tyrosine kinases present in 5% to 7% of people with NSCLC. By preventing the activity of these kinases, Alecensa reduces the viability of cancer cells.

Alecensa was FDA approved on December 11, 2015.

Alecensa side effects

Common Alecensa side effects may include:

• anemia;
• constipation;
• swelling in your face, eyelids, hands, or lower legs;
• tired feeling; or
• muscle pain.

Serious side effects and warnings

Alecensa can cause serious or life-threatening side effects.

Get emergency medical help if you have signs of an allergic reaction to Alecensa, such as hives; difficulty breathing; or swelling of your face, lips, tongue, or throat.

Serious side effects of Alecensa include the following:

Liver problems (hepatotoxicity). These are common with Alecensa and can be severe. Your healthcare provider will do blood tests at least every 2 weeks for the first 3 months, and then 1 time each month and
as needed during treatment to check your liver function. Tell your healthcare provider right away if you get any of the following signs and symptoms:

• feeling tired
• feeling less hungry than usual
• yellowing of your skin or the whites of your eyes
• dark urine
• itchy skin
• nausea or vomiting
• pain on the right side of your stomach area
• bleeding or bruising more easily than normal.

Lung problems, which may be severe or life-threatening and similar to those symptoms from lung cancer. Tell your healthcare provider right away if you have any new or worsening symptoms, including trouble breathing, shortness of breath, cough, or fever.

Kidney problems, which may be fatal. Tell your healthcare provider right away if you have a change in the amount or color of your urine, or if you get new or worsening swelling in your legs or feet.

Slow heartbeat (bradycardia). Alecensa may cause very slow heartbeats that can be severe. Your healthcare
provider will check your heart rate and blood pressure during treatment. Tell your healthcare
provider right away if you feel dizzy, lightheaded, or if you faint during treatment. Tell your
healthcare provider if you take any heart or blood pressure medicines.

Severe muscle pain, tenderness, and weakness (myalgia). Muscle problems are common with Alecensa and can be severe. Your healthcare provider will do blood tests at least every 2 weeks for the first month and as needed during treatment. Tell your healthcare provider right away if you get new or worsening signs and
symptoms of muscle problems, including unexplained muscle pain or muscle pain that does not go away,
tenderness, or weakness.

Breakdown of healthy red blood cells earlier than normal (hemolytic anemia). Hemolytic anemia can happen in some people who take Alecensa. If this happens, you may not have enough healthy red blood cells. Your
healthcare provider may temporarily stop treatment and do blood tests, if needed, to check for this problem. If you develop hemolytic anemia, your healthcare provider may either restart you at a lower dose when the
hemolytic anemia goes away or may stop your treatment. Tell your healthcare provider right away
if you experience yellow skin (jaundice), weakness or dizziness, or shortness of breath.

Call your doctor at once if you have:

• heart problems–severe dizziness, very slow heartbeats;
• a light-headed feeling, like you might pass out;
• unexplained muscle pain, tenderness, or weakness;
• lung problems – sudden chest pain or discomfort, wheezing, dry cough or cough with mucus, feeling short of breath;
• low red blood cells (anemia) – pale skin, unusual tiredness, feeling light-headed, cold hands and feet;
• kidney problems – a change in your urine color, little or no urination, swelling in your feet or ankles; or
• liver problems – stomach pain (upper right side), loss of appetite, easy bruising or bleeding, feeling tired, dark urine, jaundice (yellowing of the skin or eyes).

Your cancer treatments may be delayed or permanently discontinued if you have certain side effects.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.
