Who to screen

Who to screen
Screening can identify at-risk patients and, along with staging and monitoring, can reduce the risk of DKA and help you determine when you can intervene with TZIELD
Patients may be at risk regardless of age or family history1-3
A chart showing the peak age of Type 1 Diabetes diagnosis being 10-14 years and the median age being 24 years. In 2022, 62% of new Type 1 Diabetes cases globally occurred in people older than 20 years of age.
Age at Autoimmune T1D Diagnosis

However, those with certain family and personal history of autoimmunity may be at increased risk4,5
It's important to screen:
First-degree relatives of autoimmune T1D patients, who can have a ~15x higher risk of developing autoimmune T1D vs the general population
Those with personal or family history of select autoimmune disease, including celiac disease and thyroid disorders such as Hashimoto’s or Graves’ disease
Screening has been found to reduce DKA at Stage 3 T1D onset by ≥50%.6,7
Identify T1D at early, presymptomatic stages by screening at-risk individuals for at least 4 autoantibodies (AAbs), as recommended by the American Diabetes Association (ADA).8

Important Safety Information
TZIELD is a CD3-directed monoclonal antibody indicated to delay the onset of Stage 3 type 1 diabetes (T1D) in adults and pediatric patients aged 8 years and older with Stage 2 T1D.
  • Cytokine Release Syndrome (CRS): CRS occurred in TZIELD-treated patients during the treatment period and through 28 days after the last drug administration. Prior to TZIELD treatment, premedicate with antipyretics, antihistamines and/or antiemetics, and treat similarly if symptoms occur during treatment. If severe CRS develops, consider pausing dosing for 1 day to 2 days and administering the remaining doses to complete the full 14-day course on consecutive days; or discontinue treatment. Monitor liver enzymes during treatment. Discontinue TZIELD treatment in patients who develop elevated alanine aminotransferase or aspartate aminotransferase more than 5 times the upper limit of normal (ULN) or bilirubin more than 3 times ULN.
  • Serious Infections: Use of TZIELD is not recommended in patients with active serious infection or chronic infection other than localized skin infections. Monitor patients for signs and symptoms of infection during and after TZIELD administration. If serious infection develops, treat appropriately, and discontinue TZIELD.
  • Lymphopenia: Lymphopenia occurred in most TZIELD-treated patients. For most patients, lymphocyte levels began to recover after the fifth day of treatment and returned to pretreatment values within two weeks after treatment completion and without dose interruption. Monitor white blood cell counts during the treatment period. If prolonged severe lymphopenia develops (<500 cells per mcL lasting 1 week or longer), discontinue TZIELD.
  • Hypersensitivity Reactions: Acute hypersensitivity reactions including serum sickness, angioedema, urticaria, rash, vomiting and bronchospasm occurred in TZIELD-treated patients. If severe hypersensitivity reactions occur, discontinue TZIELD and treat promptly.
  • Vaccinations: The safety of immunization with live-attenuated (live) vaccines with TZIELD-treated patients has not been studied. TZIELD may interfere with immune response to vaccination and decrease vaccine efficacy. Administer all age-appropriate vaccinations prior to starting TZIELD.
    • Administer live vaccines at least 8 weeks prior to treatment. Live vaccines are not recommended during treatment, or up to 52 weeks after treatment.
    • Administer inactivated (killed) vaccines or mRNA vaccines at least 2 weeks prior to treatment. Inactivated vaccines are not recommended during treatment or 6 weeks after completion of treatment.
Most common adverse reactions (>10%) were lymphopenia, rash, leukopenia, and headache.
  • Pregnancy: May cause fetal harm.
  • Lactation: A lactating woman may consider pumping and discarding breast milk during and for 20 days after TZIELD administration.
