Alecensa is a cancer medicine that contains the active substance alectinib.

Alecensa is used to treat adults with a type of lung cancer called ‘non-small cell lung cancer’ (‘NSCLC’) that is ‘ALK-positive’ - this means your cancer cells have a fault in a gene that makes an enzyme called ALK (‘anaplastic lymphoma kinase’) fusion, see ‘How Alecensa works’, below.

Alecensa can be prescribed to you:

• after removal of your cancer as a post-surgical (adjuvant) treatment, or
• as the first treatment of your lung cancer that has spread to other parts of the body (advanced), or if you have been previously treated with a medicine containing ‘crizotinib’.

Alecensa blocks the action of an enzyme called ‘ALK tyrosine kinase’. Abnormal forms of this enzyme (due to fault in the gene that makes it) help encourage cancer cell growth. Alecensa may slow down or stop the growth of your cancer. It may prevent the tumour from coming back after removal by surgery. It may also help to shrink your cancer.

If you have any questions about how Alecensa works or why this medicine has been prescribed for you, ask your doctor, pharmacist or nurse.

• if you are allergic to alectinib or any of the other ingredients of this medicine (listed in section 6).

If you are not sure, talk to your doctor, pharmacist or nurse before taking Alecensa.

Talk to your doctor, pharmacist or nurse before taking Alecensa:

• if you have ever had stomach or intestine problems as holes (perforation), or if you have conditions causing inflammation inside the abdomen (diverticulitis), or if you have spread of cancer inside the abdomen (metastasis). It is possible that Alecensa may increase the risk of developing holes in the wall of your gut.
• if you have an inherited problem called ‘galactose intolerance’, ‘congenital lactase deficiency’ or ‘glucose-galactose malabsorption’.

If you are not sure, talk to your doctor, pharmacist or nurse before taking Alecensa.

Talk to your doctor right away after having taken Alecensa:

• if you are experiencing severe stomach or abdominal pain, fever, chills, sickness, vomiting, or abdominal rigidity or bloating, as these could be symptoms of a hole in the wall of your gut.

Alecensa can cause side effects that you need to tell your doctor about straight away. These include:

• liver injury (hepatotoxicity). Your doctor will take blood tests before you start treatment, then every 2 weeks for the first 3 months of your treatment and then less often. This is to check you do not have any liver problems while taking Alecensa. Tell your doctor straight away if you get any of the following signs: yellowing of your skin or the whites of your eyes, pain on the right side of your stomach area, dark urine, itchy skin, feeling less hungry than usual, nausea or vomiting, feeling tired, bleeding or bruising more easily than normal.
• slow heart beat (bradycardia).
• lung inflammation (pneumonitis). Alecensa may cause severe or life-threatening swelling (inflammation) of the lungs during treatment. The signs may be similar to those from your lung cancer. Tell your doctor straight away if you have any new or worsening signs including difficulty in breathing, shortness of breath, or cough with or without mucus, or fever.
• severe muscle pain, tenderness, and weakness (myalgia). Your doctor will do blood tests at least every 2 weeks for the first month and as needed during treatment with Alecensa. Tell your doctor straight away if you get new or worsening signs of muscle problems, including unexplained muscle pain or muscle pain that does not go away, tenderness, or weakness.
• abnormal breakdown of red blood cells (haemolytic anaemia). Tell your doctor straight away if you feel tired, weak or short of breath.

Look out for these while you are taking Alecensa. See ‘Side effects’ in section 4 for more information.
