About ROS1+ NSCLC

Moving forward with knowledge

You have been diagnosed with ROS1+ NSCLC. To better understand your unique type of cancer, we need to take a closer look at what NSCLC is. NSCLC is the most common type of lung cancer (about 80% to 85% of cases), but not all lung cancers are the same.

Understanding NSCLC

Lung cancer happens when cells in the lungs change (or are abnormal) and grow out of control. These extra cells can form a lump, called a tumor, in the lungs.

NSCLC is considered locally advanced at stages 3A, 3B, and 3C, or metastatic at stage 4. “Locally advanced” is when the cancer has spread beyond the lung but is still confined to the chest region. The term “metastatic” means it has spread to other parts of the body.

What is a biomarker test?

For people with NSCLC, a full biomarker testing panel is important because it may help find specific genetic changes (also called alterations) or proteins in your cancer cells. Biomarker test results can help your healthcare provider find what may be causing your cancer to grow and which treatment choices may be most appropriate for you.

To check for biomarkers, a biopsy is performed where either blood or a tissue sample is taken and is sent out for further laboratory testing. You may have already had a tissue biopsy that was used to diagnose NSCLC. The tissue sample may also be used for biomarker testing.

Common ways to do a biopsy include:

  • Tissue biopsy: a small piece of the tumor is removed and tested
  • Liquid biopsy: a sample of the blood is collected and tested

What is ROS1+ NSCLC?

After testing for biomarkers, your healthcare provider likely found that your cancer is ROS1+. This is a type of lung cancer where the ROS1 gene is altered (or abnormal) and causes the cancer to grow in an unusual way.

A ROS1 alteration can happen to anyone. This alteration occurs in a small number of people with lung cancer and often affects people who haven’t smoked or smoked very little. People diagnosed with ROS1+ NSCLC tend to be younger compared to the typical age of those with other types of NSCLC.

ROS1+ is rare icon

About 2% of people with NSCLC have cancer that tests positive for ROS1.

Although ROS1+ NSCLC is a rare condition, you aren’t alone. There are others just like you who are navigating this journey, learning as much as they can about their diagnosis and finding ways to move forward.

How is ROS1+ NSCLC treated?

There are targeted therapies called tyrosine kinase inhibitors (TKIs) designed specifically to target ROS1.

TKIs are a nonchemotherapy option that work differently from immunotherapy or chemotherapy. These ROS1-targeted therapies block the altered ROS1 signal, helping to slow down or stop the growth of cancer cells.

IBTROZI is a targeted oral therapy specifically designed for advanced ROS1+ NSCLC and is not chemotherapy

Summary iconSummary: About ROS1+
NSCLC

NSCLC is the most common type of lung cancer. ROS1+ NSCLC is caused by genetic changes like alterations in the ROS1 gene. Your healthcare provider uses biomarker testing, usually from a biopsy or blood, to look for genetic changes like altered ROS1. ROS1+ NSCLC is rare and only about 2% of people with NSCLC are positive for ROS1. TKIs are a type of targeted treatment used to treat ROS1+ NSCLC when the cancer has spread within the chest or to other parts of the body. These treatments are not chemotherapy. ROS1-targeted TKIs, like IBTROZI, block the altered ROS1 protein and may help slow or stop cancer cells from growing.

IBTROZI® (taletrectinib) can cause side effects, some of which can be serious, life-threatening or fatal. Side effects in clinical trials included liver problems, lung problems, changes in the electrical activity of the heart, increased uric acid in the blood, muscle problems, bone fractures, and harm to an unborn baby (if given to a pregnant woman). For more on risks see IBTROZI.com/#isi.

What is IBTROZI?

IBTROZI® (taletrectinib) is a prescription medicine used to treat adults with non-small cell lung cancer (NSCLC) that has spread within your chest or to other parts of the body and is caused by an abnormal ROS1 gene.

It is not known if IBTROZI is safe and effective in children.

IMPORTANT SAFETY INFORMATION

What is the most important information I should know about IBTROZI?

IBTROZI can cause serious side effects, including:

  • Liver problems (Hepatotoxicity). Changes in liver function can happen during treatment with IBTROZI and can lead to liver injury and death. Your healthcare provider will do blood tests to check your liver function before starting, every 2 weeks during the first 2 months of treatment, then monthly as needed during your treatment with IBTROZI. Tell your healthcare provider right away if you develop signs and symptoms of liver problems, including:
    • yellowing of your skin or the white part of your eyes (jaundice)
    • dark or "tea-colored" urine
    • light-colored stools (bowel movements)
    • loss of appetite
    • nausea or vomiting
    • pain on the upper right side of your stomach
    • feeling tired or weak
  • Lung problems (Interstitial Lung Disease/Pneumonitis). IBTROZI can cause lung problems that are severe, life-threatening, or lead to death. Tell your healthcare provider right away if you have any new or worsening symptoms of lung problems, including trouble breathing, shortness of breath, cough (with or without mucus), or fever.
  • Changes in the electrical activity of your heart (QT prolongation). QT prolongation can cause irregular heartbeats that can be life-threatening. Your healthcare provider will do tests before and during your treatment with IBTROZI to check the electrical activity of your heart and your body salts (electrolytes). Tell your healthcare provider right away if you feel faint, lightheaded, dizzy, or feel your heart beating irregularly or fast during your treatment with IBTROZI. These may be symptoms related to QT prolongation.
  • Increased uric acid level in your blood (Hyperuricemia). Your healthcare provider will check your uric acid blood level before and during your treatment with IBTROZI. Your healthcare provider may prescribe medicines to lower uric acid if needed. Tell your healthcare provider if you develop any of the following symptoms of hyperuricemia:
    • red, hot, tender, or swollen joints, especially in your big toe
    • pain in your stomach-area
    • nausea or vomiting
    • pink or brown urine
  • Muscle pain, tenderness, and weakness (Myalgia). IBTROZI can cause myalgia with or without an increase in the level of an enzyme in your blood called creatine phosphokinase (CPK), which may be a sign of muscle damage. Your healthcare provider will do blood tests to check your CPK blood levels every 2 weeks during the first month and as needed if you experience unexplained muscle pain, tenderness, or weakness with IBTROZI. Tell your healthcare provider if you develop any of these symptoms.
  • Bone fractures. IBTROZI can increase your risk of bone fractures, which may happen with or without a fall or other injury. Tell your healthcare provider if you develop pain, changes in movement, or bone abnormalities.
  • Harm to your unborn baby. IBTROZI should not be used in pregnancy. Tell your healthcare provider right away if you become pregnant or think you may be pregnant during treatment with IBTROZI.
    • If you are a female who is able to become pregnant, your healthcare provider should do a pregnancy test before starting IBTROZI. Use an effective birth control (contraception) during treatment and for 3 weeks after the last dose of IBTROZI.
    • If you are a male with a female partner who is able to become pregnant, use an effective form of contraception during treatment and for 3 weeks after the last dose of IBTROZI.

What are the most common side effects of IBTROZI?

  • The most common side effects of IBTROZI include: diarrhea, nausea, vomiting, dizziness, rash, constipation, tiredness, changes in your liver function tests, and decreased white blood cell levels.

These are not all the possible side effects of IBTROZI. Call your healthcare provider for more information or medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

What should I tell my healthcare provider before starting IBTROZI?

Before taking IBTROZI tell your healthcare provider about all your medical conditions, including if you:

  • have liver problems.
  • have lung or breathing problems other than lung cancer.
  • have any heart problems, including a condition called long QT syndrome.
  • have gout.
  • are pregnant or plan to become pregnant.
  • are breastfeeding or plan to breastfeed. It is not known if IBTROZI passes into your breast milk. Do not breastfeed during treatment and for 3 weeks after the last dose of IBTROZI.

Tell your healthcare provider about all medicines you take, including prescription and over-the-counter medicines, vitamins, or herbal supplements.

Will medications interact with IBTROZI?

IBTROZI may affect the way other medicines work, and other medicines may affect how IBTROZI works.

  • You should not start or stop any medicine before you talk with your healthcare provider who prescribed IBTROZI.

What should I avoid while taking IBTROZI?

  • Avoid taking proton pump inhibitor (PPI) or H2 blocker medicine. If you take an antacid, take it at least 2 hours before or 2 hours after taking IBTROZI.
  • You should limit time in the sun during treatment with IBTROZI. IBTROZI may make your skin sensitive to sunlight. Wear a hat and clothes that cover your skin and use sunscreen with sun protective factor (SPF) if you are in the sun during treatment with IBTROZI and for at least 5 days after your last dose of IBTROZI.
  • You should avoid grapefruit, grapefruit juice, or products that contain grapefruit during your treatment with IBTROZI. Grapefruit may increase the amount of IBTROZI in your blood, which may increase the risk of IBTROZI side effects.
