(For additional information see "Teplizumab: Drug information")
Note: The FDA-approved dose does not reflect the dose used in the premarket clinical trial due to pharmacokinetic differences between the product used in the clinical trial and the product that was FDA approved; therefore, do not use the doses used in the clinical trial (Ref). Safety: Avoid use in patients with laboratory or clinical evidence of active serious infection (including acute Epstein-Barr virus or cytomegalovirus infection) or chronic infections other than localized skin infections.
Diabetes mellitus, type 1, delay onset of symptomatic disease (stage 3):
Note: For use in patients with stage 2 type 1 diabetes mellitus (ie, at least 2 positive pancreatic islet cell autoantibodies, dysglycemia without overt hyperglycemia following an oral glucose tolerance test, and clinical history not suggestive of type 2 diabetes mellitus).
Premedicate with a nonsteroidal anti-inflammatory drug or acetaminophen, an antihistamine, and/or an antiemetic for the first 5 days of teplizumab infusions to mitigate risk of cytokine release syndrome; administer additional doses of premedication, if needed.
IV: Administer once daily for 14 consecutive days using BSA as follows:

Cytokine release syndrome (CRS) has been reported in patients treated with teplizumab, including serious cases. Symptoms may include fever, nausea, fatigue, headache, myalgia, arthralgia, increased serum alanine aminotransferase, increased serum aspartate aminotransferase, and increased total bilirubin. In clinical studies, the median duration of the CRS event was 3 days, and most cases were grade 1 and 2, although grade 3 events leading to treatment discontinuation were observed (Ref).
Mechanism: Dose-related; teplizumab-induced T-cell activation results in systemic inflammatory effects (Ref).
Onset: Rapid; most reactions occurred within 5 days of treatment initiation (range: 3 to 6 days) (Ref).
Lymphocytopenia has commonly been reported with teplizumab, including rare severe episodes (lymphocytes <500 cells/mcL). In most cases, lymphocyte levels began to recover after the fifth day of treatment and returned to baseline within 2 to 6 weeks without dose interruption (Ref). Additionally, leukopenia, neutropenia, anemia, and thrombocytopenia have been reported.
Mechanism: Lymphopenia: Dose-related; T-cell modulation results in transient reductions in lymphocytes from peripheral blood (Ref).
Hypersensitivity reactions, including anaphylaxis, angioedema, and serum sickness, have been reported with teplizumab use. Mild to moderate skin rash has been frequently reported; serious rash has been rarely reported.
Bacterial infection and viral infection, including serious infection, have occurred with teplizumab use. Reported infections include gastroenteritis, cellulitis, pneumonia, abscesses, sepsis, wound infection, Epstein-Barr infection, herpes simplex infection, cytomegalovirus disease, and varicella zoster infection (Ref).
Mechanism: Dose-related; due to suppression of T-cell immune function (Ref).
The following adverse drug reactions and incidences are derived from product labeling unless otherwise specified. Adverse reactions reported in children, adolescents, and adults. Note: The FDA-approved dose does not reflect the dose used in the premarket clinical trial due to pharmacokinetic differences between the product used in the clinical trial and the product that was FDA approved; therefore, adverse reactions and incidences reported in the product labeling may differ from the product that was FDA approved (FDA 2021; Herold 2019).
>10%:
Dermatologic: Skin rash
Hematologic & oncologic: Leukopenia, lymphocytopenia
Nervous system: Headache
1% to 10%:
Gastrointestinal: Diarrhea, nausea
Hematologic & oncologic: Neutropenia
Hepatic: Increased serum alanine aminotransferase
Hypersensitivity: Cytokine release syndrome, serum sickness
Infection: Serious infection (including abscess, cellulitis, gastroenteritis, pneumonia, sepsis, wound infection)

Frequency not defined: Infection: Bacterial infection, viral infection (including cytomegalovirus disease, Epstein-Barr infection, herpes simplex infection, and varicella zoster infection) (FDA 2021)
There are no contraindications listed in the manufacturer's labeling.
Concerns related to adverse effects:
• Immunogenicity: Development of anti-teplizumab antibodies, including neutralizing antibodies, may occur during therapy. Antibody-positive patients may have an increased incidence of adverse events (eg, rash).
Disease-related concerns:
• Liver function: Avoid use in patients with ALT or AST >2 times ULN or bilirubin >1.5 times ULN.
Dosage form specific issues:
• Polysorbate 80: Some dosage forms may contain polysorbate 80 (also known as Tweens). Hypersensitivity reactions, usually a delayed reaction, have been reported following exposure to pharmaceutical products containing polysorbate 80 in certain individuals (Isaksson 2002; Lucente 2000; Shelley 1995). Thrombocytopenia, ascites, pulmonary deterioration, and renal and hepatic failure have been reported in premature neonates after receiving parenteral products containing polysorbate 80 (Alade 1986; CDC 1984). See manufacturer's labeling.
Other warnings/precautions:
• Immunizations: The safety of immunization with live-attenuated vaccines in patients treated with teplizumab has not been established; teplizumab may interfere with the immune response to vaccination and decrease vaccine efficacy. Administer all age-appropriate immunizations before initiating therapy, if possible. Administer live vaccines ≥8 weeks prior to initiation or >52 weeks after completing treatment; administer inactivated vaccines ≥2 weeks prior to initiation or >6 weeks after completing treatment.

Administration of teplizumab should be avoided for at least 30 days prior to planning a pregnancy to minimize fetal exposure.
Teplizumab is a humanized monoclonal antibody (IgG1). Human IgG crosses the placenta. Fetal exposure is dependent upon the IgG subclass, maternal serum concentrations, placental integrity, newborn birth weight, and GA, generally increasing as pregnancy progresses. The lowest exposure would be expected during the period of organogenesis and the highest during the third trimester (Clements 2020; Palmeira 2012; Pentsuk 2009).
In utero exposure to teplizumab may cause immunosuppression in the newborn. Administration of teplizumab should be avoided during pregnancy.
Health care providers are encouraged report pregnancies exposed to teplizumab to the Provention Bio Inc adverse event reporting line (1-844-778-2246).
Monitor CBC and liver chemistries (eg, AST, ALT, total bilirubin) prior to initiating therapy. Monitor liver enzymes, lymphocytes, and signs/symptoms of cytokine-release syndrome, infection, or hypersensitivity throughout therapy. In teplizumab approval trials, CBC and liver chemistries were obtained daily to identify toxicities that may require alterations in therapy.
Teplizumab-mzwv binds to CD3 (a cell surface antigen) on both CD4+ and CD8+ T cells, which leads to an increase in the proportion of regulatory T cells and of exhausted CD8+ T cells in peripheral blood. The mechanism behind the delay in progression from stage 2 to stage 3 type 1 diabetes mellitus may involve partial agonistic signaling and deactivation of pancreatic beta cell autoreactive T lymphocytes.
