Akeega® 50 mg/500 mg film-coated tablets – patient leaflet, side effects, dosage

1 What Akeega is and what it is used for

Akeega is a medicine that contains two active substances: niraparib and abiraterone acetate, and works in two different ways. Akeega is used to treat adult men with prostate cancer who have changes in certain genes and whose prostate cancer has spread to other parts of the body (also called metastatic prostate cancer).

Niraparib is a type of cancer medicine called a PARP inhibitor. PARP inhibitors block an enzyme called poly [adenosine diphosphate-ribose] polymerase (PARP). PARP helps cells repair damaged DNA. When PARP is blocked, cancer cells cannot repair their DNA, resulting in tumour cell death and helping to control the cancer.

Abiraterone stops your body from making testosterone; this can slow the growth of prostate cancer.

When you take this medicine, your doctor will also prescribe another medicine called prednisone or prednisolone. This is to lower your chances of getting high blood pressure, having too much water in your body (fluid retention), or having reduced levels of a chemical known as potassium in your blood.

2 What you need to know before you take Akeega

Do not take Akeega:

• if you are allergic to niraparib or abiraterone acetate or any of the other ingredients of this medicine - listed in section 6.
• if you are a woman who is or can become pregnant.
• if you have severe liver damage.
• in combination with Ra-223 treatment (which is used to treat prostate cancer). This is because of a possible increase in the risk of bone fracture or death.

Do not take this medicine if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before taking this medicine.

Warnings and precautions

Talk to your doctor or pharmacist before or while taking this medicine if you have:

• low blood cell counts. Signs and symptoms you need to look out for include fatigue, fever or infection, and abnormal bruising or bleeding. Akeega may also lower your blood cell counts. Your doctor will test your blood regularly throughout your treatment.

  • high blood pressure or heart failure or low blood potassium (low blood potassium may increase the risk of heart rhythm problems), have had other heart or blood vessel problems, have an irregular or rapid heart rate, shortness of breath, gained weight rapidly, or swelling in the feet, ankles, or legs. Your doctor will measure your blood pressure regularly throughout your treatment.
  • headaches, vision changes, confusion, or seizure. These may be signs of a rare neurological side effect named posterior reversible encephalopathy syndrome (PRES) that has been associated with use of niraparib, an active ingredient of Akeega.
  • high fever, fatigue and other signs and symptoms of severe infection.
  • blood clots in the lungs or legs, or have had them in the past.
  • liver problems.
  • low or high levels of sugar in the blood.
  • muscle weakness and/or muscle pain.

If any of the above apply to you (or you are not sure), talk to your doctor or pharmacist before taking this medicine. If you develop abnormal blood cell counts for a long period of time while taking Akeega, this may be a sign of more serious problems with the bone marrow such as ‘myelodysplastic syndrome’ (MDS) or ‘acute myeloid leukaemia’ (AML). Your doctor may want to test your bone marrow to check for these problems.

Before taking Akeega, also talk to your doctor or pharmacist about:

• the effect Akeega may have on your bones.
• taking prednisone or prednisolone (another medicine you must take with Akeega).

If you are not sure if any of the above apply to you, talk to your doctor or pharmacist before taking this medicine.

Blood monitoring

Akeega may affect your liver, but you may not notice any symptoms of liver problems. When you are taking this medicine, your doctor will therefore check your blood periodically to look for any effects on your liver.

Children and adolescents

This medicine is not for use in children and adolescents. If Akeega is accidentally swallowed by a child or adolescent, take them to the hospital immediately and take this package leaflet with you to show to the emergency doctor.

Other medicines and Akeega

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines. This is because Akeega can affect the way some other medicines work. Also, some other medicines can affect the way Akeega works. Treatment with medicines that stop the body from producing testosterone, may increase the risk of heart rhythm problems. Tell your doctor if you are receiving medicine:

• to treat heart rhythm problems (e.g., quinidine, procainamide, amiodarone and sotalol);
• known to increase the risk of heart rhythm problems (e.g., methadone), used for pain relief and part of drug addiction detoxification; moxifloxacin, an antibiotic; antipsychotics, used for serious mental illnesses.

Tell your doctor if you are taking any of the medicines listed above.

Akeega with food

• This medicine must not be taken with food (see section 3, “Taking Akeega”), as this may increase your risk of side effects.
