A chance to get more time before Stage 3 T1D when daily insulin is needed

TZIELD could mean more time to learn about eventual symptoms and risks and more time to get ready for daily insulin management.

“I am being compensated by Sanofi to share my story.”

John, TZIELD Patient
[Compensated by Sanofi]
“I had gone for some routine blood work. I had a high A1C, high blood glucose levels. And I spoke with the nurse practitioner, and she told me, ‘John, you have type 2 diabetes.’ I was shocked. I have no family history of type 1 or type 2 diabetes. I didn't have any symptoms or anything like that. I've been very active in my life. So, to hear this news was… took me completely by surprise. I went low-carb diet, exercising multiple times a day. My goal was to have an A1C of normal ranges within three months. And I was able to do that. However, I would see spikes that… no matter what I ate. My rising glucose levels just were not making sense.”

A second opinion
“The new primary care physician tested me for type 1 diabetes-related autoantibodies. And that confirmed that I had stage 2 type 1 diabetes.”

“I met with my endocrinologist, and I remember her saying, ‘I think you might be a good candidate for this TZIELD.’ I knew that TZIELD wasn't a cure for type one diabetes, but that it could delay the onset of stage 3 type one diabetes, which was important to me.”

What is TZIELD?
TZIELD is a prescription medicine used to delay the onset of Stage 3 type 1 diabetes, which is when your body can’t make enough insulin on its own and may require insulin injections. TZIELD is for adults and children 8 years of age and older who have Stage 2 type 1 diabetes. This means that they have tested positive for 2 or more type 1 diabetes-related autoantibodies, have abnormal blood sugar levels, and do not have type 2 diabetes.

It is not known if TZIELD is safe and effective in children under 8 years of age.

IMPORTANT SAFETY INFORMATION

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

TZIELD may cause serious side effects. These include:

  • Cytokine release syndrome (CRS). Signs and symptoms may start during the first 5 days of TZIELD treatment and could include fever, nausea, feeling tired (fatigue), headache, muscle and joint pain, or increased liver enzymes in your blood. Tell your healthcare provider right away if you develop any signs and symptoms of CRS during treatment with TZIELD
  • Decrease in white blood cells. TZIELD may cause a decrease in a type of white blood cell called lymphocytes. A decrease in white blood cells is a serious, but common side effect that can affect your body’s ability to fight infections. A decrease in white blood cell counts can happen after your first dose. Your white blood cell counts will start to go back to normal after your fifth dose of TZIELD. Some people may develop longer and more severe decreases in lymphocytes

Your healthcare provider will do blood tests to check your liver and your complete blood counts before you start treatment and during treatment with TZIELD. During and after your treatment with TZIELD, your healthcare provider will check for serious side effects, as well as other side effects, and treat you as needed. Your healthcare provider may temporarily or completely stop your treatment with TZIELD, if you develop liver problems, have a serious infection, or if your blood counts stay too low.

What should I tell my healthcare provider before receiving TZIELD?

Before or after receiving TZIELD, tell your healthcare provider about all your medical conditions, including if you:

  • have a serious infection or an infection that does not go away or keeps coming back
  • have recently received or are scheduled to receive an immunization (vaccine). TZIELD may affect how well a vaccine works. Tell your doctor that you are receiving TZIELD before receiving a vaccine
  • are pregnant or plan to become pregnant. TZIELD may harm your unborn baby. Do not receive TZIELD during pregnancy and at least 30 days before a planned pregnancy
  • are breastfeeding or plan to breastfeed. It is not known if TZIELD passes into your breast milk and if it can harm your baby. Talk to your healthcare provider about the best way to feed your baby if you receive TZIELD

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

What are the possible side effects of TZIELD?

The most common side effects of TZIELD include:

  • rash
  • leukopenia (decrease in white blood cell counts)
  • headache

These are not all of the possible side effects of TZIELD. Talk to your healthcare provider for more information, and tell them about any side effects you notice. You may report side effects to the FDA at www.fda.gov/medwatch or 1-800-FDA-1088.

John: anyone can get T1D

John was shocked to learn that someone as active as him, with no family history, could get type 1 diabetes. But T1D can affect anyone at any time.

The time to screen is now

T1D has no visible signs or symptoms in its early stages. So don’t wait, screening early is the first step you or your loved one can take to reduce the risk of serious complications at T1D diagnosis, including an emergency hospitalization event.

TZIELD makes it possible to help take control of what’s next and delay the onset of insulin-dependent T1D, but the window to treat can be short. AAb screening is the first step you and your doctor can take to determine if TZIELD could be the right option.

Important Safety Information and Indication

What is the most important information I should know about TZIELD? TZIELD may cause serious side effects. These including:
  • Viral Reactivation. Epstein-Barr virus (EBV) and cytomegalovirus (CMV) are common viruses that may stay inactive in your body after an initial infection. TZIELD may cause these viruses to become active again which, especially in patients with a weakened immune system, can become serious and potentially life-threatening. These viral reactivations can happen during treatment with TZIELD and up to 2 months after your last dose. Your healthcare provider will test you for active EBV and CMV infections before treatment with TZIELD. Contact your healthcare provider right away if you develop symptoms of an infection during or after treatment with TZIELD (such as fever, swollen glands, or fatigue).
  • Cytokine release syndrome (CRS). Signs and symptoms may start during the first 5 days of TZIELD treatment and could include fever, nausea (with or without vomiting), feeling tired (fatigue), headache, muscle and joint pain, or increased liver enzymes in your blood. Tell your healthcare provider right away if you develop any signs and symptoms of CRS during treatment with TZIELD. 
  • Decrease in white blood cells. TZIELD may cause a decrease in a type of white blood cell called lymphocytes. A decrease in white blood cells is a serious, but common side effect that can affect your body’s ability to fight infections. A decrease in white blood cell counts can happen after your first dose. Your white blood cell counts will start to go back to normal after your fifth dose of TZIELD. Some people may develop longer and more severe decreases in lymphocytes.

Your healthcare provider will do blood tests to check for active infections, verify your liver function and your complete blood counts before you start treatment and during treatment with TZIELD. During and after your treatment with TZIELD, your healthcare provider will check for serious side effects, as well as other side effects, and treat you as needed. Your healthcare provider may temporarily or completely stop your treatment with TZIELD, if you develop liver problems, have a serious infection or viral reactivation, or if your blood counts stay too low.  

What should I tell my healthcare provider before receiving TZIELD? Before or after receiving TZIELD, tell your healthcare provider about all your medical conditions, including if you:
  • have any of the conditions or symptoms listed in the section “What is the most important information I should know about TZIELD?”
  • have a weakened immune system, including if you have Down syndrome.
  • have a serious infection or an infection that does not go away or keeps coming back (chronic). 
  • have recently received or are scheduled to receive an immunization (vaccine). TZIELD may affect how well a vaccine works. Tell your healthcare provider that you are receiving treatment with TZIELD before receiving a vaccine.
  • are pregnant or plan to become pregnant. TZIELD may harm your unborn baby.  Do not receive TZIELD during pregnancy and at least 30 days before a planned pregnancy.
