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

You will likely be in a hospital before and after getting TECELRA.

TECELRA may cause side effects that can be severe or life-threatening. Call your healthcare provider or get emergency help right away if you get any of the following:

   Fever (100.4°F/38°C or higher)
   Chills/Shivering
   Difficulty breathing
   Fast or irregular heartbeat
   Low blood pressure
   Fatigue
   Severe nausea, vomiting, or diarrhea
   Severe headache
   New skin rash

Tell all your healthcare providers that you were treated with TECELRA.
What is TECELRA?

TECELRA is a medicine, called a genetically modified autologous T cell immunotherapy, that is used to treat synovial sarcoma. It is used when other kinds of treatment do not work.

TECELRA is different from other cancer medicines because it is made from your own white blood cells that are made to recognize and attack your cancer cells.

Your healthcare provider will perform tests to see if TECELRA is right for you.

Before you get TECELRA, tell your healthcare provider about all your medical problems, including:

   Seizure, stroke, confusion, or memory loss
   Heart, liver or kidney problems
   Low blood pressure
   Lung or breathing problems
   Recent or active infection
   Past infections which can be reactivated following treatment with TECELRA
   Low blood counts
   Pregnancy, you think you may be pregnant, or plan to become pregnant
   Breastfeeding
   Taking a blood thinner

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

How will I get TECELRA?

Since TECELRA is made from your own white blood cells, your blood will be collected by a process called "leukapheresis" (loo-kah-fur-ee-sis). This gets sent to a company to make the TECELRA for you.

It takes about 6 weeks to get your TECELRA back, but the time may vary.

While your TECELRA is being made, your healthcare provider may give you other medicines to stabilize your cancer.

Before you get your TECELRA, you will get 4 days of chemotherapy to prepare your body.

When your TECELRA is ready, you get a tube (intravenous catheter) placed into your vein and your dose of TECELRA will be given in one or more infusion bags. The infusion may take up to 60 minutes for each infusion bag.

After getting TECELRA, you will be monitored daily at the healthcare facility, for at least 7 days after the infusion.

You should plan to stay close to a healthcare facility for at least 4 weeks. Your healthcare provider will check to see that your treatment is working and help you with any side effects that may occur.

Your healthcare provider will do blood tests to follow your progress. It is important that you have your blood tested. If you miss a scheduled appointment for your collection of blood, call your healthcare provider as soon as possible to reschedule.
