🩺 Clinical

Label name THYMOGLOBULIN 25 MG VIAL Ingredient Anti-Thymocyte Globulin,Rabbit
📖 What it is MedlinePlus · NLM

Anti-thymocyte globulin is used to prevent or treat kidney transplant rejection (attack of the transplanted organ by the immune system of the person receiving the organ). It is also used to treat aplastic anemia (condition in which the body does not make enough new blood cells). Anti-thymocyte globulin is in a class of medications called Immunosuppressants. It works by decreasing the activity of the immune system.

Inactive ingredient FAQ

Are inactive ingredients the same for every manufacturer?
No. Inactive ingredients can differ by manufacturer, dosage form, strength, and package / product version.
Why might an inactive ingredient be missing?
Some SPLs do not provide a complete structured inactive-ingredient list, and older or unusual labels may only include the information in narrative text.
Can inactive ingredients matter?
Yes. They can matter for allergies, intolerances, dyes, gluten / lactose concerns, preservatives, and formulation differences — but confirm with a pharmacist or the manufacturer when it’s clinically important.

💲 Pricing

A drug doesn't have one price. Each row is a different public payment system, and none is what you'd pay at the counter — that depends on your insurance. The ⓘ on each row explains what it measures.

Price systemPer mLPer package
Retail pharmacies payNADAC · weekly Not in the retail survey — common for institutional, discontinued, or low-volume packs.
Medicaid paysCMS SDUD · 12 mo No recent Medicaid claims on file for this NDC — rare and low-volume NDCs are suppressed in the public data.
Medicare drug plans payPart D · quarterly No Part D plan price is available for this NDC in our data.
Medicare Part B allowsASP · J7511 $1,057.791 / J7511 unit
Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

Questions about this listing

Why is there no price listed?
The pricing shown on our NDC pages comes from CMS NADAC, a voluntary survey of retail community pharmacy invoices. CMS does not publish a NADAC for every NDC — packages outside the retail survey (institutional and hospital products, bulk packages, discontinued items, and many OTC items) may never receive one. A missing price reflects the survey's scope, not this product's actual cost, and does not mean the product is free or unavailable.
Is the NDC printed on the package the same as the 11-digit billing NDC?
Yes, they identify this exact package in different formats. The FDA registers it as 58468-0080-1, which is what is printed on the packaging and shown on DailyMed. Insurance claims use a fixed 11-digit 5-4-2 format, so the short segment is padded with a leading zero: 58468-0080-01, written without dashes as 58468008001. The Identity section at the top of this page lists every form of this code.
What do the three segments of this NDC mean?
In 58468-0080-01, the first segment (58468) is the labeler code FDA assigned to Genzyme Corporation; the middle segment (0080) identifies this specific product — its ingredient, strength, and dosage form; and the last segment (01) identifies this exact package size and type. Together they name one specific package of one specific product.
Is this package still being marketed?
Yes, per the latest FDA NDC Directory data on this page: this package is listed as actively marketed, with no marketing end date reported by Genzyme Corporation. Listing status can change — the directory data on this page refreshes weekly.
Who lists this product with the FDA?
Genzyme Corporation is the labeler of record for this NDC — the company under whose FDA-assigned code the package is listed. The labeler may be the manufacturer itself or a distributor marketing the product under its own code.
Do I need a prescription for this product?
This NDC is listed with FDA as a prescription product, so it is dispensed under a prescriber's order. Your pharmacist can tell you whether any over-the-counter forms of the same medication exist.
Does this product have a billing J-code?
Yes — this NDC cross-references HCPCS code J7511 for medical-claim billing (typically used when a product is administered in a clinical setting rather than dispensed at a retail pharmacy). See the Billing section on this page.
This page identifies an FDA-listed package (the NDC) and reports public regulatory and pricing data about the listing. It is reference information, not a medical recommendation — talk to your pharmacist or prescriber about your own medication.

1 INDICATIONS AND USAGE THYMOGLOBULIN is indicated for the prophylaxis and treatment of acute rejection in adult and pediatric patients receiving a kidney transplant in conjunction with concomitant immunosuppression. THYMOGLOBULIN is an immunoglobulin G indicated for the prophylaxis and treatment of acute rejection in adult and pediatric patients receiving a kidney transplant in conjunction with concomitant immunosuppression. ( 1 )

⏱️ Dosage and Administration ~3 min read

2 DOSAGE AND ADMINISTRATION The first dose should be infused over at least 6 hours; doses on subsequent days should be infused over at least 4 hours. ( 2.2 ) Premedication with corticosteroids, acetaminophen, and/or an antihistamine prior to each infusion is recommended. ( 2.2 ) The THYMOGLOBULIN dose should be reduced by one-half if the white blood cell (WBC) count is between 2,000 and 3,000 cells/mm 3 or if the platelet count is between 50,000 and 75,000 cells/mm 3 .

Stopping THYMOGLOBULIN treatment should be considered if the WBC count falls below 2,000 cells/mm 3 or if the platelet count falls below 50,000 cells/mm 3 . ( 2.3 ) Indication Dose Prophylaxis of acute rejection 1.5 mg/kg of body weight administered daily for 4 to 7 days Treatment of acute rejection 1.5 mg/kg of body weight administered daily for 7 to 14 days For complete dosing instructions, see full prescribing information. ( 2 )

2.1Dosing Information For intravenous use only Prophylaxis of Acute Rejection The recommended dosage of THYMOGLOBULIN for prophylaxis of acute rejection in patients receiving a kidney transplant is 1.5 mg/kg of body weight administered daily with the first dose initiated prior to reperfusion of the donor kidney. The usual duration of administration is 4 to 7 days. Treatment of Acute Rejection The recommended dosage of THYMOGLOBULIN for treatment of acute rejection in patients receiving a kidney transplant is 1.5 mg/kg of body weight administered daily for 7 to 14 days.

Dosing for THYMOGLOBULIN is different from dosing for other anti-thymocyte globulin (ATG) products because protein composition and concentrations vary depending on the source of ATG. The prescribing physician must ensure that the dose prescribed is appropriate for the ATG product being administered.

2.2Recommended Dosing Regimen Administer the first dose of THYMOGLOBULIN over a minimum of 6 hours; administer doses on subsequent days over at least 4 hours [see Warnings and Precautions (5.2) ] . Premedicate with corticosteroids, acetaminophen, and/or an antihistamine 1 hour prior to each infusion of THYMOGLOBULIN to reduce the incidence and intensity of infusion-related reactions [see Warnings and Precautions (5.2) and Adverse Reactions (6.1) ] .

2.3Dose Modifications Monitor patients for adverse reactions during and after infusion. Monitor total white blood cell and platelet counts during and after THYMOGLOBULIN therapy. Reduce the THYMOGLOBULIN dose by one-half if the white blood cell (WBC) count is between 2,000 and 3,000 cells/mm 3 or if the platelet count is between 50,000 and 75,000 cells/mm 3 .

Consider stopping THYMOGLOBULIN treatment if the WBC count falls below 2,000 cells/mm 3 or if the platelet count falls below 50,000 cells/mm 3 .

2.4Recommended Concomitant Medication THYMOGLOBULIN is used with concomitant immunosuppressants. Administer prophylactic antifungal and antibacterial therapy if clinically indicated [see Warnings and Precautions (5.4) ] . Antiviral prophylactic therapy is recommended for patients who are seropositive for cytomegalovirus (CMV) at the time of transplant and for CMV-seronegative patients scheduled to receive a kidney from a CMV-seropositive donor [see Warnings and Precautions (5.4) ].

2.5Instructions for Dilution and Administration Reconstitution After calculating the number of vials needed, using aseptic technique, reconstitute each vial of THYMOGLOBULIN with 5 mL of Sterile Water for Injection, USP (SWFI).

4 CONTRAINDICATIONS THYMOGLOBULIN is contraindicated in patients with history of allergy or anaphylactic reaction to rabbit proteins or to any product excipients, or who have active acute or chronic infections that contraindicate any additional immunosuppression [see Warnings and Precautions (5.2 , 5.4) and Adverse Reactions (6.2) ] . Allergy or anaphylactic reaction to rabbit proteins or to any product excipients, or active acute or chronic infections which contraindicate any additional immunosuppression ( 4 )

⚠️ Warnings and Cautions ~2 min read

5 WARNINGS AND PRECAUTIONS THYMOGLOBULIN should only be used by physicians experienced in immunosuppressant therapy in transplantation. ( 5.1 ) Hypersensitivity and infusion-related reactions: THYMOGLOBULIN infusion could result in an anaphylactic reaction. Close compliance with the recommended infusion time may reduce the incidence and severity of infusion-related reactions.

( 5.2 ) Cytopenias including anemia, neutropenia, and thrombocytopenia have occurred with THYMOGLOBULIN administration ( 6 ) and require monitoring of blood counts. Adjust dose accordingly to reverse cytopenias. Thrombotic microangiopathy (TMA) has occurred in patients treated with THYMOGLOBULIN for kidney transplantation, particularly when concomitantly administered with calcineurin inhibitors.

( 5.3 ) Infection: Infections and reactivation of infections have been reported. Monitor patients and administer anti-infective prophylaxis. ( 5.4 ) Malignancy: Incidence of malignancies may increase.

( 5.5 ) Immunization with attenuated live vaccines is not recommended for patients who have recently received THYMOGLOBULIN. ( 5.6 ) THYMOGLOBULIN may interfere with rabbit antibody–based immunoassays and with cross-match or panel-reactive antibody cytotoxicity assays. ( 5.7 )

5.1Management of Immunosuppression To prevent over-immunosuppression, physicians may wish to decrease the dose of the maintenance immunosuppression regimen during the period of THYMOGLOBULIN use.

5.2Hypersensitivity and Infusion-Related Reactions Severe hypersensitivity and infusion-related reactions, including fatal anaphylaxis and severe cytokine release syndrome (CRS), have been reported with the use of THYMOGLOBULIN [see Adverse Reactions (6) ] . Severe acute CRS can cause serious cardiorespiratory events and/or death. Close compliance with the recommended dosage and infusion time may reduce the incidence and severity of infusion-related reactions.

Slowing the infusion rate may minimize the risk of infusion-related reactions. If a hypersensitivity or infusion-related reaction occurs, terminate the infusion immediately and provide supportive treatment according to clinical practice.

5.3Cytopenias Cytopenias including anemia, neutropenia, and thrombocytopenia have occurred with THYMOGLOBULIN administration [see Adverse Reactions (6) ] . Monitor blood counts after THYMOGLOBULIN administration. Adjust dose accordingly to reverse cytopenias [see Dosage and Administration (2.3) ] .

Thrombotic microangiopathy (TMA) has occurred in patients treated with THYMOGLOBULIN for kidney transplantation, particularly when concomitantly administered with calcineurin inhibitors.

5.4Infection THYMOGLOBULIN is routinely used in combination with other immunosuppressive agents. Infections (bacterial, fungal, viral and protozoal), reactivation of infection (particularly cytomegalovirus [CMV]) and sepsis have been reported after THYMOGLOBULIN administration in combination with multiple immunosuppressive agents [see Adverse Reactions (6) ] . These infections can be fatal.

Monitor patients carefully and administer appropriate anti-infective treatment when indicated [see Dosage and Administration (2.4) ] .

5.5Malignancy Malignancies with fatal outcomes have been reported in patients treated with THYMOGLOBULIN [see Adverse Reactions (6) ]. Use of immunosuppressive agents, including THYMOGLOBULIN, may increase the risk of malignancies, including lymphoma or lymphoproliferative disorders.

5.6Immunizations The safety of immunization with attenuated live vaccines following THYMOGLOBULIN therapy has not been studied; therefore, immunization with attenuated live vaccines is not recommended for patients who have recently received THYMOGLOBULIN.

5.7Laboratory Tests THYMOGLOBULIN may interfere with rabbit antibody–based immunoassays and with cross-match or panel-reactive antibody cytotoxicity assays. THYMOGLOBULIN has not been shown to interfere with any routine clinical laboratory tests that do not use immunoglobulins.

🤒 Adverse Reactions ~3 min read

6 ADVERSE REACTIONS The most common adverse reactions and laboratory abnormalities (incidence >5% higher than comparator) are urinary tract infection, abdominal pain, hypertension, nausea, shortness of breath, fever, headache, anxiety, chills, increased potassium levels in the blood, low counts of platelets and white blood cells. ( 6 ) To report SUSPECTED ADVERSE REACTIONS, contact Genzyme Corporation at 1-800-633-1610 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The most common adverse reactions and laboratory abnormalities (incidence >5% higher than comparator) are urinary tract infection, abdominal pain, hypertension, nausea, shortness of breath, fever, headache, anxiety, chills, increased potassium levels in the blood, and low counts of platelets and white blood cells.

Prophylaxis of Acute Rejection The safety of THYMOGLOBULIN compared to Active Comparator for the prophylaxis of acute rejection in patients receiving a kidney transplant were evaluated in a randomized, open-label, international, multicenter trial in patients receiving solitary kidneys from deceased donors (n=278; Study 1). Table 1: Adverse Reactions Adverse reactions are treatment emergent adverse events (TEAE) reported as related to the study agent in at least 1 patient. and Laboratory Abnormalities Reported More Frequently (incidence Number (percentage) is shown regardless of causal relationship. >5%) Following THYMOGLOBULIN versus Active Comparator basiliximab Adverse Reaction [n (%) ] THYMOGLOBULIN (N=141) Active Comparator (N=137) Urinary tract infection 55 (39%) 36 (26%) Pyrexia 39 (28%) 25 (18%) Headache 26 (18%) 17 (12%) Hyperlipidemia 21 (15%) 9 (7%) Anxiety 20 (14%) 12 (9%) Chills 13 (9%) 5 (4%) Laboratory Abnormalities Hyperkalemia: blood potassium ≥5.5 mmol/L; Leukopenia: WBC <3000 cells/mm 3 .

In the Active Comparator group, 1 patient developed renal cancer.

Infections Infections occurred in 76% of THYMOGLOBULIN-treated patients (severe in 23%), and in 63% of Active Comparator-treated patients (severe in 15%). Infections occurring in ≥5% of the patients in either treatment group during the 12-month follow-up are summarized in Table 2. Urinary tract infection was the most frequent type of infection, and was reported as severe in 9% of THYMOGLOBULIN-treated patients and in 2% of Active Comparator-treated patients.

CMV infections were reported more frequently in the Active Comparator group, with an incidence of 6% (severe in 1%) in THYMOGLOBULIN-treated patients and of 18% (severe in 7%) in Active Comparator-treated patients. Patients who were CMV-positive at the time of transplant, as well as CMV-negative recipients of transplants from CMV-positive donors, were required to receive antiviral prophylaxis for 3 months after transplant.

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action The mechanism of action by which polyclonal antilymphocyte preparations suppress immune responses is not fully understood. Possible mechanisms by which THYMOGLOBULIN may induce immunosuppression in vivo include: T-cell clearance from the circulation and modulation of T-cell activation, homing, and cytotoxic activities. THYMOGLOBULIN includes antibodies against T-cell markers such as CD2, CD3, CD4, CD8, CD11a, CD18, CD25, CD44, CD45, HLA-DR, HLA Class I heavy chains, and ß2 micro-globulin.

In vitro , THYMOGLOBULIN (concentrations >0.1 mg/mL) mediates T-cell suppressive effects via inhibition of proliferative responses to several mitogens. In patients, T-cell depletion is usually observed within a day after initiating THYMOGLOBULIN therapy. THYMOGLOBULIN has not been shown to be effective for treating antibody-mediated (humoral) rejections.

12.3Pharmacokinetics After an intravenous dose of 1.25 to 1.5 mg/kg/day (over 4 hours for 7–11 days) 4–8 hours post infusion, THYMOGLOBULIN levels were on average 21.5 mcg/mL (10–40 mcg/mL) with a half-life of 2–3 days after the first dose, and 87 mcg/mL (23–170 mcg/mL) after the last dose. During the THYMOGLOBULIN Phase 3 randomized trial for the treatment of acute rejection, of the 108 of 163 patients evaluated, anti-rabbit antibodies developed in 68% of the THYMOGLOBULIN-treated patients, and anti-horse antibodies developed in 78% of the Active Comparator-treated patients.

No controlled studies have been conducted to study the effect of anti-rabbit antibodies on repeat use of THYMOGLOBULIN. However, to ensure that T-cell depletion is achieved upon retreatment with THYMOGLOBULIN, monitoring the lymphocyte count is recommended. T-cell counts based on data collected from a limited number of patients (n=12) in this study, are presented in the chart below.

These data were collected using flow cytometry (FACSCAN, Becton-Dickinson). chart

📋 Description 209 words

11 DESCRIPTION THYMOGLOBULIN ® (anti-thymocyte globulin [rabbit]) is a purified, pasteurized, immunoglobulin G, obtained by immunization of rabbits with human thymocytes. This immunosuppressive product contains cytotoxic antibodies directed against antigens expressed on human T-lymphocytes. THYMOGLOBULIN is a sterile, lyophilized powder for intravenous administration after reconstitution with sterile Water for Injection, USP (SWFI).

Each single-dose 10 mL vial contains 25 mg of anti-thymocyte globulin (rabbit), 50 mg glycine, 50 mg mannitol and 10 mg sodium chloride. After reconstitution with 5 mL SWFI, each vial of reconstituted product contains approximately 5 mg/mL of THYMOGLOBULIN, of which >90% is rabbit gamma immune globulin (IgG). The reconstituted solution has a pH of 6.5 to 7.2.

Human red blood cells are used in the manufacturing process to deplete cross-reactive antibodies to non–T-cell antigens. The manufacturing process is validated to remove or inactivate potential exogenous viruses. All human red blood cells are from U.S.-registered or FDA-licensed blood banks.

A virus removal step (nanofiltration, using a 20 nm filter) and a viral inactivation step (pasteurization, i.e., heat treatment of active ingredient at 60°C/10 hr) are performed for each lot. Each THYMOGLOBULIN lot is released following potency testing (lymphocytotoxicity and anti-CD2 binding inhibition), and cross-reactive antibody testing (hemagglutination, platelet agglutination, and fibroblast toxicity assays on every lot).
