Lumacaftor/ivacaftor, sold under the brand name Orkambi among others, is a combination of lumacaftor and ivacaftor used to treat people with cystic fibrosis who have two copies of the F508del mutation. It is unclear if it is useful in cystic fibrosis due to other causes. It is taken by mouth.

Common side effects include shortness of breath, nausea, diarrhea, feeling tired, hearing problems, and rash. Severe side effects may include liver problems and cataracts. Ivacaftor increases the activity of the CFTR protein, while lumacaftor improves protein folding of the CFTR protein.

It was approved for medical use in the United States in 2015 and in Canada in 2016. In the United Kingdom the medication costs the NHS more than £4,000 a month as of 2018. In the United States it costs more than $US 22,000 a month as of 2018. While its use was not recommended in the United Kingdom as of 2018, pricing was agreed upon in 2019 and it is expected to be covered by November of that year.
