Pronunciation: elle-a-fib-ran-or
Generic name: elafibranor
Brand name: Iqirvo
Dosage form: oral tablet (80 mg)
Drug class: Miscellaneous metabolic agents
What is elafibranor?
Elafibranor is used to treat primary biliary cholangitis (PBC) in combination with ursodeoxycholic acid (UDCA) in adults who have not responded well to UDCA, or used alone in patients unable to tolerate UDCA. It is an oral tablet that is taken once daily.
The brand name of elafibranor is Iqirvo, and it is made by Ipsen Biopharmaceuticals, Inc. There is no generic.
Elafibranor (Iqirvo) gained FDA approval on 10 June 2024 under the accelerated approval designation. Continued approval may be contingent on a positive clinical benefit in reducing alkaline phosphatase (ALP), with no increases in liver toxicity, being found in further clinical trials.
Mechanism
Elafibranor (Iqirvo) is a dual agonist of PPAR-alpha and PPAR-delta receptors. These receptors help regulate lipid and glucose metabolism, mitochondrial fatty acid metabolism, and oxidative stress. Elafibranor works by activating these receptors, reducing inflammation, improving bile acid metabolism, and reducing bile acid toxicity in patients with PBC.
Clinical trials report that patients treated with elafibranor experienced a greater reduction in mean ALP within 4 weeks of treatment that was generally maintained through week 52.
Elafibranor belongs to the drug class called peroxisome proliferator-activated receptor (PPAR) agonists.
Side effects
The most common side effects of elafibranor are:
- weight gain
- diarrhea
- nausea and vomiting
- joint pain
- stomach pain
- constipation
- muscle problems
- bone fractures
- gastroesophageal reflux disease (GERD)
- dry mouth
- weight loss
- rash.
Serious side effects and warnings
Elafibranor can cause the following serious side effects:
- Muscle problems (such as myalgia, myopathy, or rhabdomyolysis). Treatment with elafibranor may cause muscle pain or worsen existing pain and can increase the level of an enzyme in
your blood called creatine phosphokinase (CPK), which can be signs of muscle damage. Your healthcare provider should test for muscle weakness or pain before and during treatment. If there is new onset or worsening of muscle pain then your healthcare provider may examine you and perform a blood test to check your levels of creatine phosphokinase (CPK). Stop taking elafibranor and call your healthcare provider right away if you have any of the following signs or symptoms:- severe muscle pain
- unexplained muscle weakness
- unexplained soreness
- dark, reddish urine.
- Bone fractures. Taking elafibranor may increase your risk of bone fractures. Tell your healthcare provider about any bone fractures, if you develop pain, or have changes in your ability to move around.
- Liver problems. Elafibranor may cause abnormal liver blood test results. Your healthcare provider should do tests before starting and during treatment with elafibranor to check your liver function. Tell your healthcare provider right away if you have any of the following signs or symptoms of worsening liver problems during treatment:
- swelling of your stomach area (abdomen) from a build-up of fluid
- yellowing of your skin or the whites of your eyes
- black, tarry, or bloody stools
- coughing up or vomiting blood, or your vomit looks like “coffee grounds”
- mental changes such as confusion, being sleepier than usual or harder to wake up, slurred speech, mood swings, or changes in personality.
Tell your healthcare provider right away if you have any of the following symptoms during treatment with elafibranor and they are severe or do not go away:
-
- stomach-area (abdomen) pain
- nausea, vomiting, diarrhea
- loss of appetite or weight loss
- new or worsening fatigue
- weakness
- fever and chills
- light-headedness
- less frequent urination.
- Allergic reactions have occurred in some people taking elafibranor. The reactions happened 2 to 30 days after taking it and included symptoms such as rash, itching, trouble breathing, and swelling of your face, lips, tongue, or throat. If you have any of these symptoms, stop taking elafibranor and call your healthcare provider right away or go to the nearest hospital emergency room.
- Blockage of the bile duct. Taking elafibranor may increase your risk of gallstone development. Call your healthcare provider right away if you develop any signs or symptoms of gallstones, including pain in the upper right stomach area or yellowing of the skin
May cause harm to an unborn baby. If you are a female with the ability to become pregnant, your healthcare provider may conduct a pregnancy test before prescribing elafibranor.
Your healthcare provider may tell you to stop taking elafibranor temporarily or permanently if there are changes to either your liver tests or CPK levels.
It is not known if elafibranor is safe and effective in children under 18 years of age.
