Frequently Asked Questions

TREATMENT OVERVIEW

What is TRODELVY?

TRODELVY is a prescription medicine used to treat adults with a certain type of breast cancer known as triple-negative (HR and HER2 negative) that has spread to other parts of the body (metastatic) and who received at least 2 therapies for metastatic disease.

TRODELVY is approved based on medical studies that measured how many patients responded and how long they responded. Continued approval may depend on benefit demonstrated in additional medical studies.

It is not known if TRODELVY is safe and effective in people with moderate or severe liver problems or in children.

How is TRODELVY thought to work?

TRODELVY is a type of drug called an antibody-drug conjugate, or ADC for short. ADCs join together 3 parts into 1 drug: an antibody, a linker, and an anti-cancer drug. The antibody looks for a specific protein, in this case Trop-2, which can be found in high levels on cancer cells. The linker connects the anti-cancer drug to the antibody. The anti-cancer drug kills cancer cells once they’re found.

TRODELVY binds to cancer cells with Trop-2.

This is how TRODELVY was shown to work in laboratory studies. The clinical benefit of these observations is unknown.

How is TRODELVY given?

You will receive TRODELVY from your doctor as an infusion into your vein. Each treatment cycle is 21 days. Doses are given once a week for 2 weeks, followed by 1 week off.

  • You will receive the first dose of TRODELVY over 3 hours. If you tolerate the first dose well, future doses may be given over 1 to 2 hours
  • Before each dose of TRODELVY, you will receive medicines to help prevent infusion reactions, and nausea and vomiting
  • You will be monitored for side effects during and for at least 30 minutes after you receive each infusion of TRODELVY
  • Your healthcare provider may slow down or temporarily stop your infusion of TRODELVY if you have a life-threatening infusion-related reaction
  • Your healthcare provider will decide how long you will continue to receive TRODELVY

What are some of the things that need to be done before I am given TRODELVY?

Before your first infusion, you may be given medicines such as antihistamines, corticosteroids, or H1 or H2 blockers. You may also receive a fever reducer. These medicines can help prevent reactions to the infusion. You may also be given medicine to help prevent nausea and vomiting.

On the day of your first infusion, you may have a short physical exam to check your blood pressure, pulse, breathing, and temperature. Your height and weight will also be measured to find the right dosage of TRODELVY. An intravenous (IV) tube will be put in your arm and a blood sample may be taken.

How often will I receive TRODELVY?

TRODELVY is an IV infusion. It is given once a week for 2 weeks, followed by 1 week off. Each treatment cycle is 3 weeks, which means treatment cycles repeat every 21 days.

How long will I be on TRODELVY?

You and your doctor will decide how many treatment cycles you receive. This may be based on factors such as whether your tumor has responded to treatment or your body’s ability to tolerate treatment.

SIDE EFFECTS

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

TRODELVY can cause serious side effects, including:

  • Low white blood cell count (neutropenia): Low white blood cell counts are common with TRODELVY and can sometimes be severe and lead to infections that can be life-threatening. Your healthcare provider should check your blood cell counts during treatment with TRODELVY. If your white blood cell count is too low, your healthcare provider may need to lower your dose of TRODELVY, give you a medicine to help prevent low blood cell count with future doses of TRODELVY, or in some cases may stop TRODELVY. Your healthcare provider may need to give you antibiotic medicines if you develop fever while your white blood cell count is low. Contact your doctor immediately if you experience fever, chills, cough, shortness of breath, or burning or pain when you urinate.
  • Severe diarrhea: Diarrhea is common with TRODELVY and can also be severe. Your healthcare provider should monitor you for diarrhea and give you medicine as needed to help control your diarrhea. If you lose too much body fluids (dehydration) your healthcare provider may need to give you fluids and electrolytes to replace body salts. If diarrhea happens later in your treatment, your healthcare provider may check you to see if the diarrhea may be caused by an infection. Your healthcare provider may decrease your dose or stop TRODELVY if your diarrhea is severe and cannot be controlled with antidiarrheal medicines. Call your doctor right away:
    • the first time that you get diarrhea during treatment with TRODELVY
    • if you have black or bloody stools
    • if you have symptoms of losing too much body fluid (dehydration) and body salts, such as lightheadedness, dizziness, or faintness
    • if you are unable to take fluids by mouth due to nausea or vomiting
    • if you are not able to get your diarrhea under control within 24 hours

NAUSEA AND VOMITING

Your doctor may provide medications to help prevent nausea and vomiting. Follow the directions from your doctor. These tips may also help:

  • Eat 5 to 6 small meals or snacks a day rather than 3 large meals
    • Eat bland foods, such as toast and crackers
    • Try eating small amounts of foods that are high in calories
  • Slowly sip cool, clear liquids such as ginger ale, apple juice, broth, or tea throughout the day to stay hydrated
  • Try to take deep, slow breaths or get fresh air when you begin to feel sick
  • If you are vomiting, ice chips or frozen juice chips may help you take in fluids more easily

DIARRHEA

Antidiarrheal medications may be given to you by your doctor. Contact your doctor immediately if you are unable to get your diarrhea under control within 24 hours after infusion. The following tips may help control diarrhea:

  • Slowly sip cool, clear liquids throughout the day to stay hydrated
  • Eat frequent, small meals that are bland and low fiber such as bananas, white rice, and toast
  • Avoid alcohol, caffeine, greasy or spicy foods, and limit dairy products and raw vegetables

FEELING TIRED (fatigue)

It’s common for treatment to leave you feeling weak and tired. Help manage your fatigue using the following tips:

  • Plan time to relax and rest, and create a schedule that works for you
  • Take short naps and try to get 7 to 8 hours of sleep each night
  • Try to stay active, but talk with your doctor before starting a new exercise routine
  • Drink plenty of water and eat well
  • Reduce stress by trying meditation, yoga, reading, or keeping a diary

LOW RED BLOOD CELL COUNT (anemia)

A low red blood cell count can be common with treatment. This can leave you feeling weak and tired. Following these tips may help:

  • Limit activities and get plenty of rest
  • Take short naps and try to get 7 to 8 hours of sleep each night
  • Eat a well-balanced diet that includes proteins (such as meat, fish, eggs, dairy, and nuts) and drink plenty of water

LOW WHITE BLOOD CELL COUNT (neutropenia)

TRODELVY may lower your neutrophils, a type of white blood cell. This can put you at higher risk of infection. The following tips may help reduce the risk of infection:

  • Contact your doctor immediately if you experience fever, chills, or other signs of infection
  • Wash your hands often with soap and warm water
  • Avoid large crowds and stay away from people who are sick
  • Thoroughly wash raw fruits and vegetables before eating them

HAIR LOSS (alopecia)

  • Check to see if your insurance company will cover the cost for a wig
  • Wear a hair net at night or sleep on a satin pillowcase to keep hair from coming out in clumps
  • Protect your scalp from the sun by using sunscreen and wear a hat or scarf outside
  • The effectiveness and safety of cooling caps is still being researched. If you are curious about this option, talk to your doctor. Also, ask if the treatment center has experience in using cooling caps and how successful they have been

TREATMENT DAYS

How long does a TRODELVY infusion take?

Your first infusion will take approximately 3 hours. After that, if prior treatment was well tolerated, your infusions will take 1 to 2 hours.

What would be helpful for me to know on my treatment days?

Treatment days can be exhausting. Here are a few tips to consider:

  • If you think you will feel too tired to drive, arrange for transportation to and from the infusion center
  • Bring things to pass the time. Books, audio books, and magazines are great choices. Headphones and a tablet or phone for music, shows, movies, or podcasts can be helpful
  • Consider downloading a meditation app
  • Wear comfortable clothing and bring a blanket in case you start to feel cold
  • Until you know how TRODELVY will affect you, consider asking someone to be home to help you on treatment days. Once you have had a few treatments, you can have a better sense of how you will feel and what kind of help you may or may not need on treatment days

Will I need to have a port for my infusion?

You do not need to have a port inserted to receive treatment with TRODELVY. However, if you already have a port, it can be used for the infusion.

A port can help reduce the number of times a nurse needs to insert a needle into your vein. This can be helpful if your veins are small or damaged.

What should I expect on treatment days?

Your doctor may recommend the following on treatment days:

Pre-infusion: You may be given medicines before your infusion to help prevent infusion reactions, including a fever reducer, antihistamines, or corticosteroids. Your doctor may also give you medicine to help reduce or prevent nausea or vomiting.

Infusion: Your first infusion will take approximately 3 hours. Your doctor will observe you during the infusion. After that, if prior treatment was well tolerated, your infusions with TRODELVY will take 1 to 2 hours.

Observation: After each infusion, your doctor will watch for reactions for at least 30 minutes. If you experience any side effects while taking TRODELVY, tell your doctor right away. Please read the Important Safety Information at the bottom of this website.

How can my doctor and I tell if the treatment is working?

Your doctor will tell how well your treatment is working by doing different exams or tests. Ask your doctor to explain the results to you and if your treatment is working.

Keep in mind that side effects do not tell you if the treatment is, or is not, working.
