What ORKAMBI is used for

ORKAMBI is for the chronic treatment of cystic fibrosis (CF) in patients age 6 years and older who have two copies of the F508del mutation in the CFTR gene.

What is cystic fibrosis?

Cystic fibrosis is caused by genetic defects that limit the flow of chloride and water through cell membranes. As a result, the mucus in the lungs (and other organs) becomes thick and sticky, clogs the lungs and makes it easier for germs to grow. ORKAMBI is a medicine that works by improving the flow of chloride and water in patients with cystic fibrosis who have a certain genetic defect.

How ORKAMBI works

ORKAMBI belongs to a group of medicines called “cystic fibrosis transmembrane conductance regulator (CFTR) modulators.”

The CFTR protein is a chloride ion channel that is normally present at the cell surface of epithelial cells where it transports chloride ions out of the cell in multiple organs. In people who have two copies of the F508del mutation in the CFTR gene, the amount of CFTR protein at the cell surface is much lower than normal. The small amount of CFTR protein that reaches the cell surface does not function properly, as the chloride ion channel remains closed more often than normal.

ORKAMBI is a combination product that contains:

  • a CFTR corrector (lumacaftor), which increases the amount of working CFTR at the cell surface
  • and a CFTR potentiator (ivacaftor), which makes the CFTR protein at the cell surface function better because the chloride ion channel is open more often.

ORKAMBI therefore allows more chloride ions to get transported out of cells in multiple organs.

ORKAMBI is not addictive.

When you must not take it

Do not take ORKAMBI if you have an allergy to:

  • any medicine containing lumacaftor or ivacaftor, the active ingredients in ORKAMBI.

Some of the symptoms of an allergic reaction may include:

  • shortness of breath
  • wheezing or difficulty breathing
  • swelling of the face, lips, tongue or other parts of the body

Before you start to take it

Tell your doctor if you have allergies to any other medicines, foods, preservatives, or dyes.

Respiratory events such as shortness of breath or chest tightness were seen in patients when starting ORKAMBI, especially in patients who have poor lung function. If you have poor lung function, your doctor may monitor you more closely when you start ORKAMBI.

Do not give ORKAMBI to children under 6 years of age. The safety and effectiveness of this medicine in children under 6 years of age have not been established.

Abnormality of the eye lens (cataract) without any effect on vision has been noted in some children receiving ORKAMBI.

Your doctor may perform eye examinations before and during treatment with ORKAMBI.

Laboratory Testing
Your doctor will do some blood tests to check your liver prior to and while you are taking ORKAMBI, particularly during the first year (every 3 months), and once a year after that.

Abnormal blood tests of the liver have been seen in some people receiving ORKAMBI.

If you have had abnormal blood tests of the liver in the past, your doctor may order blood tests to test your liver more often.

Talk to your doctor if you have been told you have liver or kidney disease or if you are taking any other medicine, as your doctor may need to adjust the dose of ORKAMBI.

How to take ORKAMBI

Follow all directions given to you by your doctor and pharmacist carefully. These directions may differ from the information contained in this leaflet.

How much to take

Your doctor will tell you how many tablets you need to take each day. This may depend on your condition and whether or not you are taking any other medicines.

The recommended dose for patients 12 years of age and over (children, adolescents, or adults) is two tablets (200 mg lumacaftor/125 mg ivacaftor in each tablet) every 12 hours. The total number of tablets is 4 per day for a total of 800 mg lumacaftor/500 mg ivacaftor.

The recommended dose for patients 6 to 11 years of age is two tablets (100 mg lumacaftor/125 mg ivacaftor in each tablet) every 12 hours. The total number of tablets is 4 per day for a total of 400 mg lumacaftor/500 mg ivacaftor.

If you have liver problems, your doctor may need to reduce the dose.

How to take it

Take 2 tablets of ORKAMBI every 12 hours by mouth with a fat-containing food. Meals and snacks recommended in CF guidelines or meals recommended in standard nutritional guidelines contain adequate amounts of fat. Examples of meals or snacks that contain fat are those prepared with butter or oils or those containing eggs, cheeses, nuts, chocolate, whole milk, whole-milk dairy products, meats, avocados, oily fish, and soy-based products (tofu).

Taking ORKAMBI with fat-containing food is important to get the right levels of medicine in your body.

ORKAMBI is always given in combination with the medicines you usually use.

You must keep using all your medicines unless your doctor tells you to stop using any of them.

How long to take it

Take ORKAMBI for as long as your doctor tells you. Your doctor will determine if your treatment should be stopped.

If you forget to take it

Take the missed dose if less than 6 hours have passed since the time you should have taken the dose. Otherwise, wait until your next scheduled dose as you normally would.

Do not take a double dose to make up for the dose that you missed. This may increase the chance of you getting an unwanted side effect.

If you are not sure what to do, talk to your doctor or pharmacist.

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (telephone Australia 13 11 26) for advice, or go to the Emergency Department at the nearest hospital, if you think that you or anyone else may have taken too much ORKAMBI. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
