Clinical Trials
US Phase 3 Study
Thymoglobulin adverse events are generally manageable or reversible. In the US Phase 3 controlled clinical trial (n=163) comparing the efficacy and safety of Thymoglobulin and Atgam, there were no significant differences in clinically significant adverse events between the two treatment groups (Table 2). Malignancies were reported in 3 patients who received Thymoglobulin and in 3 patients who received Atgam during the one-year follow-up period. These included two post-transplant lymphoproliferative diseases (PTLDs) in the Thymoglobulin group and two PTLDs in the Atgam group.

Infections occurring in both treatment groups during the 3-month follow-up are summarized in Table 3. No significant differences were seen between the Thymoglobulin and Atgam groups for all types of infections, and the incidence of cytomegalovirus (CMV) infection was equivalent in both groups. (Viral prophylaxis was by the center’s discretion during antibody treatment, but all centers used gancyclovir infusion during treatment.)

Post-marketing Experience
The following adverse reactions have been identified during post approval use of Thymoglobulin. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Infusion-Associated Reactions and Immune System Disorders
IARs may occur following the administration of Thymoglobulin and may occur as soon as the first or second infusion during a single course of Thymoglobulin treatment. Clinical manifestations of infusion-associated reactions IARs have included some of the following signs and symptoms: fever, chills/rigors, dyspnea, nausea/vomiting, diarrhea, hypotension or hypertension, malaise, rash, and/or headache. IARs with Thymoglobulin are generally manageable with a reduction in infusion rates and/or with medications. Serious and fatal anaphylactic reactions have been reported. The fatalities occurred in patients who did not receive epinephrine during the event.
IARs consistent with cytokine release syndrome (CRS) have been reported. Severe and potentially life-threatening CRS have also been reported. Post-marketing reports of severe CRS have included cardiorespiratory dysfunction (including hypotension, acute respiratory distress syndrome, pulmonary edema, myocardial infarction, tachycardia, and/or death).
During post-marketing surveillance, reactions such as fever, rash, arthralgia, and/or myalgia, indicating possible serum sickness, have been reported. Serum sickness tends to occur 5 to 15 days after onset of Thymoglobulin therapy. Symptoms are manageable with corticosteroid treatment.
Adverse Events Due to Immunosuppression
Infections, reactivation of infection, and sepsis have been reported after Thymoglobulin administration in combination with multiple immunosuppressive agents. Malignancies including, but not limited to post-transplant lymphoproliferative disorder (PTLD) and other lymphomas as well as solid tumors have been reported. These adverse events were reported with use of a combination of multiple immunosuppressive agents.
