Your doctor and you will decide if the benefits outweigh the risk of using Kymriah.
Since Kymriah is made from your own white blood cells, your healthcare provider has to take some of your blood. This is called “leukapheresis.” It takes 3 to 6 hours and may need to be repeated. A tube (intravenous catheter) will be placed in your vein to collect your blood.
Your blood cells are frozen and sent to the manufacturing site to make Kymriah. It takes about 3-4 weeks to make Kymriah, but the time may vary.
Before you get Kymriah, your healthcare provider may give you chemotherapy for a few days to prepare your body.
When your body is ready, your healthcare provider will give you Kymriah through a tube (intravenous catheter) in your vein. This usually takes less than one hour.
You should plan to stay within 2 hours of the location where you received your treatment for at least 4 weeks after getting Kymriah. Your healthcare provider will check to see if your treatment is working and help you with any side effects that occur.
The Kymriah dose you receive is based on your weight. Your healthcare provider will determine the right dose for you.
The one-time Kymriah dose is typically given 2-14 days after receiving chemotherapy.
Kymriah is provided in a single-dose unit containing chimeric antigen receptor (CAR)-positive viable T cells based on the patient weight reported at the time of leukapheresis. The dose is:
- For patients 50 kg or less: administer 0.2 to 5.0 x 106 CAR-positive viable T cells per kg body weight
- For patients above 50 kg: administer 0.1 to 2.5 x 108 CAR-positive viable T cells
If Kymriah is administered by a healthcare provider in a medical setting, it is unlikely that an overdose will occur. However, if overdose is suspected, seek emergency medical attention.
Keep all your appointments with your doctor and the laboratory. Your doctor will order certain lab tests to check your body's response to Kymriah.
