Tecartus (brexucabtagene autoleucel) is an immunotherapy known as chimeric antigen receptor (CAR) T-cell therapy. It’s used to mantle cell lymphoma (MCL) and acute lymphocytic leukemia (ALL) in adults when other treatments haven’t worked well. Treatment involves taking T-cells from your own body, programming them to better find cancer cells, and then infusing them back to your body so they can fight cancer. The entire treatment process, including preparation and recovery, can take over a month. Tecartus (brexucabtagene autoleucel) can cause serious side effects such as cytokine release syndrome (CRS) and nervous system problems.
Your immune system can not only help fight off infections, but certain immune cells (T-cells) can also fight cancer. Sometimes, cancer cells try to hide from the T-cells. So in order for T-cells to work best to fight cancer, they need to tell the difference between healthy and cancer cells.
Tecartus (brexucabtagene autoleucel) is a type of immunotherapy, also called CAR-T therapy. During treatment, your T-cells are removed from your body and sent to a lab. There, they’re programmed specifically to find and attack cancer cells, such as lymphoma or leukemia cells, in your body. Once ready, the T-cells are infused back into your body to destroy cancer cells.

Side effects that you should report to your care team as soon as possible:
Side effects that usually do not require medical attention (report these to your care team if they continue or are bothersome):
Works in a more targeted way than traditional chemotherapy
Recommended treatment for certain people with mantle cell lymphoma (MCL)
Given as a one-time treatment
Can cause a serious reaction called cytokine release syndrome (CRS)
Treatment requires a multi-step process that takes over a month
Can't drive for at least 2 months after the infusion
Your oncology team needs to closely monitor you for several weeks after you receive Tecartus (brexucabtagene autoleucel) because treatment can lead to serious side effects. You'll need to stay close by the treatment center where you received Tecartus (brexucabtagene autoleucel) for at least 3 weeks after your treatment. If needed, ask your healthcare team about how to plan for your stay and recommended places for lodging.
If you develop a temperature of 100.4 Fahrenheit or higher, seek medical help right away. This means you have a fever. A fever with Tecartus (brexucabtagene autoleucel) can be serious, because it can mean you have an infection or it can be an early sign of cytokine release syndrome (CRS).
Let your oncology team know right away if you notice symptoms of cytokine release syndrome (CRS), such as chills, fever, tiredness, and trouble breathing. These can happen days after you receive Tecartus (brexucabtagene autoleucel). If you have CRS, your care team will need to give you medical attention right away to prevent life-threatening complications.
Because Tecartus (brexucabtagene autoleucel) treatment can weaken your immune system, you’re at risk for developing serious infections, even months after your treatment. You can help prevent infection by washing your hands often, avoiding crowds, and washing raw fruits and vegetables thoroughly before eating them.
It's unclear how live vaccines might affect Tecartus (brexucabtagene autoleucel) treatment. To be safe, you should avoid getting any live vaccines within 6 weeks of the start of chemotherapy (lymphodepletion). Also, avoid live vaccines until after your immune system has recovered from Tecartus (brexucabtagene autoleucel). Your oncology team will let you know when it’s safe for you to receive live vaccines.
It's best to avoid driving or doing activities that needs lot of focus and attention for at least 2 months after you receive Tecartus (brexucabtagene autoleucel). This is because Tecartus (brexucabtagene autoleucel) can cause some serious side effects after the infusion, including dizziness and coordination problems. Please work with your caregiver, family, or friends to plan transportation to and from appointments, as well as for help at home during this time.
Tecartus (brexucabtagene autoleucel) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Cytokine release syndrome (CRS) is a potentially life-threatening immune reaction that the body can have to the Tecartus (brexucabtagene autoleucel) infusion. Most people who experienced CRS had symptoms within the first week after receiving Tecartus (brexucabtagene autoleucel) and symptoms usually lasted for 1-2 weeks. Symptoms of CRS can include fever, tiredness, chills, and trouble breathing. Rarely, people can also develop other serious immune-related reactions such as hemophagocytic lymhohistiocytosis (HLH) or macrophage activation syndrome (MAS). These complications can cause organ damage and are life-threatening.
Your oncologist will monitor you for symptoms for several weeks after your infusion. If you develop symptoms of CRS, get medical help right away. Typically, you’ll need to go to the hospital for treatment with corticosteroids and a medication called Actemra (tocilizumab) to manage it.
Tecartus (brexucabtagene autoleucel) can cause nervous system problems. Common symptoms include headache, tremor, and feeling confused. More serious symptoms include trouble speaking or problem understanding others. Symptoms typically appear within the first week of the Tecartus (brexucabtagene autoleucel) infusion and can last for several weeks.
Your oncology team will monitor you for symptoms of nervous system problems closely after you receive Tecartus (brexucabtagene autoleucel). You’ll need to stay at or close to the treatment center for at least 3 weeks after your infusion so you can get regular check ups and receive medical attention if needed.
Because Tecartus (brexucabtagene autoleucel) can cause serious side effects such as cytokine release syndrome (CRS) and nervous system problems, it's only available through a special program called Risk Evaluation and Mitigation Strategy (REMS). Some requirements of this program including ensuring the healthcare facility where you receive treatment to be certified and to keep certain medications used to manage side effects, such as Actemra (tocilizumab), available in case you need it.
Tecartus (brexucabtagene autoleucel) treatment, including the lymphodepleting chemotherapy before T-cell infusion, can lower blood cell counts in your body. This might last longer than 2 months after the Tecartus (brexucabtagene autoleucel) infusion. Having lower blood cell counts puts you at higher risk for infections, bleeding, and anemia.
Your oncology team will closely monitor your blood cell counts after Tecartus (brexucabtagene autoleucel) treatment. Make sure you go to all lab appointments so that your care team recommends so that they can keep a close eye on your blood cell counts.
People who received Tecartus (brexucabtagene autoleucel) have developed serious and life-threatening infections, including bacterial, viral, and fungal infections. Tecartus (brexucabtagene autoleucel) can cause your white blood cell (WBC) levels to drop, which can raise your risk for getting sick. People who had hepatitis B in the past might have a new infection (hepatitis B reactivation) after starting Tecartus (brexucabtagene autoleucel). Your oncology team will monitor your WBC levels with lab tests, and they might prescribe medications, such as antibiotics or antivirals, to help protect you from serious infections.
You can lower your risk of getting sick by washing your hands often and avoiding crowds. Check your temperature regularly, and call your provider right away if your temperature is 100.4 degrees Fahrenheit or higher. Contact your healthcare team right away if you have any signs or symptoms of infection such as fever, body aches, and chills.
People who receive Tecartus (brexucabtagene autoleucel) might be at higher risk for developing T-cell-related cancers. Your oncology team will monitor you for new cancers regularly after Tecartus (brexucabtagene autoleucel) treatment. Ask your care team if you’re concerned about the risk of cancers from Tecartus (brexucabtagene autoleucel).
Some people taking Tecartus (brexucabtagene autoleucel) experienced low immunoglobulin levels. Immunoglobulins are proteins that are an important part of your immune system, and help fight infection. When your immunoglobulins are low, this raises your risk for getting sick.
Your oncology team will monitor your immunoglobulin levels. If they’re too low, you might need to take an antibiotic to protect you from infection, or receive a medication called intravenous immunoglobulin (IVIG) to replace immunoglobulins in your body.
More research is needed to understand how Tecartus (brexucabtagene autoleucel) treatment affects your body’s response to vaccines. Your oncologist will ask you to avoid live vaccines at least 6 weeks before you start low-dose chemotherapy for Tecartus (brexucabtagene autoleucel), until your immune system recovers.
People who receive Tecartus (brexucabtagene autoleucel) infusion might experience allergic reactions. You're at higher risk for allergic reactions if you're sensitive to the preservative called dimethyl sulfoxide (DMSO) in the medication or to gentamicin. Tell your nurse right away if you have any symptoms of an allergic reaction during your infusion, such as itching, trouble breathing, rash, swelling, or fast heartbeat.
Tecartus (brexucabtagene autoleucel) treatment might cause nervous system changes that can include tiredness, confusion, and seizures. Don’t drive or participate in activities that would be dangerous if you couldn’t focus for 2 months after treatment. Talk with your oncology team and caregivers so that you have a plan in place to help you with transportation to appointments, chores at home, and emotional support, before you start Tecartus (brexucabtagene autoleucel).
Tecartus (brexucabtagene autoleucel) is usually given at a qualified treatment center or in a hospital setting. The treatment process takes several stages:
Blood collection: Your immune cells are collected from your body. Your T cells are separated, while the rest of your immune cells are infused back into your body. This process takes 3 to 4 hours.
Making Tecartus: Your T-cells are sent to a lab and made into Tecartus that’s specific for you. This step takes about 2-3 weeks.
Pre-treatment with chemotherapy: To prepare your body to receive Tecartus, your oncologist will prescribe 3 days of chemotherapy, typically cyclophosphamide and fludarabine.
Receiving Tecartus: Two days (sometimes longer) after last dose of chemotherapy, your oncologist will infuse Tecartus into the vein as a one-time infusion over 30 minutes.
After treatment, you’ll need to stay at or near the qualified treatment center for at least 3 weeks so your oncology team can monitor your recovery and check for side effects.
