When does hepatotoxicity start and how long does it last?

On average hepatotoxicity begins within the first 3 months of treatment. Lorlatinib can cause liver enzyme elevations 3 days after starting treatment, and lasts for 15 days.

How serious is hepatotoxicity?

Severity most often experienced is grade 1 or 2

How likely is it that I will experience hepatotoxicity?

Lorlatinib: hepatotoxicity is uncommon. Alectinib: 38% of people will experience hepatotoxicity. Crizotinib: 36% of people will experience hepatotoxicity.

Prevention Strategies

  • Tell your healthcare team if you have a history of liver problems.

    Liver function tests are monitored through bloodwork. These tests should be taken at the start of treatment and  every 2 weeks during the first 2-3 months of treatment.

    Why: this helps catch changes in liver function early and treat them before they become a problem.

  • Don’t smoke or drink alcohol.

    Eat healthy fats, fruits, vegetables, and whole grains.

    Why: Alcohol and the chemicals found in cigarettes (such as nicotine and tar) are toxic to the liver. ALKi themselves can cause liver damage so the liver is already under stress.

  • Talk to your doctor about medications, supplements, and herbal products that you use:

    • Rifampin is an antibiotic mainly used to treat tuberculosis or meningitis.

    • St. John's wort is a herbal product that can be found in oral supplements, teas, or creams, and is used to treat depression and symptoms of menopause.

    Why: these products affect ALKi medications and can increase the risk of liver injury.

Management Strategies

  • Based on the grade (or severity) of hepatotoxicity your doctor will make adjustments to your medication.

    Mild to moderate impairments require no adjustment. Your healthcare team will continue monitoring bloodwork.

  • Based on the grade (or severity) of hepatotoxicity your doctor will make adjustments to your medication.

    Significant impairments require a temporary pause of medication until liver function returns to normal.

    If liver function does not improve, your healthcare team might reduce the dose of ALKi.

  • Based on the grade (or severity) of hepatotoxicity your doctor will make adjustments to your medication.

    Severe impairments require greater dose reductions or to permanently discontinue ALKi treatment.

    Your healthcare team will likely recommend another type of ALKi or alternative treatment.

Emergent Symptoms
