THROMBIN-JMI- thrombin, topical (bovine)
Pfizer Laboratories Div Pfizer Inc

WARNING: SEVERE BLEEDING AND THROMBOSIS COMPLICATIONS

  • THROMBIN-JMI® can cause fatal severe bleeding or thrombosis. Thrombosis may result from the development of antibodies against bovine thrombin. Bleeding may result from the development of antibodies against factor V. These may cross-react with human factor V and lead to its deficiency.
  • Do not re-expose patients to THROMBIN-JMI if there are known or suspected antibodies to bovine thrombin and/or factor V.
  • Monitor patients for abnormal coagulation laboratory values, bleeding, or thrombosis.

1 INDICATIONS AND USAGE

THROMBIN-JMI is topical bovine thrombin indicated to aid hemostasis whenever oozing blood and minor bleeding from capillaries and small venules is accessible and control of bleeding by standard surgical techniques (such as suture, ligature, or cautery) is ineffective or impractical.

In various types of surgeries, solutions of THROMBIN-JMI may be used in conjunction with an Absorbable Gelatin Sponge, USP for hemostasis.

2 DOSAGE AND ADMINISTRATION

For topical use on the surface of bleeding tissue only. Do not inject.

2.1 Reconstitution

  • For routine use, reconstitute THROMBIN-JMI with sterile isotonic saline at a recommended concentration of 1,000 to 2,000 International Units per mL.
  • Where bleeding is profuse, as from abraded surfaces of liver or spleen, concentrations of 1,000 International Units per mL may be required.
  • For general use in plastic surgery, dental extractions, skin grafting, etc. solutions containing approximately 100 International Units per mL are frequently used. Prepare intermediate strengths to suit the needs of the case by diluting the contents of the THROMBIN-JMI container with an appropriate volume of sterile isotonic saline. THROMBIN-JMI can be used in a dry form on oozing surfaces.
  • In instances where a concentration of approximately 1,000 units per mL is desired, the contents of the vial of sterile isotonic saline diluent may be transferred into the THROMBIN-JMI container with a sterile syringe or sterile transfer device.
  • For use with GEL-FLOW™ NT, reconstitute THROMBIN-JMI 5,000 IU powder with 5 mL sterile isotonic saline and use Thrombin-JMI Thrombin solution according to the directions for use in the GEL-FLOW™ NT package insert.

2.2 Administration

Topical application of THROMBIN-JMI

  1. The recipient surface should be sponged (not wiped) free of blood before THROMBIN-JMI is applied.
  2. A spray may be used or the surface may be flooded using a sterile syringe and small gauge needle. The most effective hemostasis results occur when the THROMBIN-JMI mixes freely with the blood as soon as it reaches the surface.
  3. Sponging of the treated surfaces should be avoided to assure that the clot remains securely in place.

Use in conjunction with Absorbable Gelatin Sponge

Consult the Absorbable Gelatin Sponge, USP labeling for complete information for use prior to utilizing the following thrombin saturated sponge procedure.

  1. Prepare THROMBIN-JMI solution to desired strength.
  2. Immerse sponge strips of the desired size in THROMBIN-JMI solution. Knead the sponge strips vigorously with moistened, gloved fingers to remove trapped air, thereby facilitating saturation of the sponge.
  3. Apply saturated sponge to bleeding area. Hold in place with a pledget of cotton or a small gauze sponge until hemostasis occurs.

Use in conjunction with GEL-FLOW™ NT

4 CONTRAINDICATIONS

  • Do not inject directly into the circulatory system. Because of its action in the clotting mechanism, THROMBIN-JMI can cause extensive intravascular clotting or death.
  • Do not re-expose patients to THROMBIN-JMI if there are known or suspected antibodies to bovine thrombin and/or factor V.
  • Do not administer to patients with a history of hypersensitivity to THROMBIN-JMI, its components and/or to material of bovine origin.
  • Do not use for treatment of severe or brisk arterial bleeding.

5 WARNINGS AND PRECAUTIONS

Warning: Severe Bleeding and Thrombosis Complications

5.1 Hypersensitivity Reactions

  • Allergic reactions, including anaphylactic/anaphylactoid reactions, have been reported following administration of THROMBIN-JMI.
  • Institute intensive supportive measures and treat individual symptoms. Secure the airway and establish adequate respiratory exchange.

5.2 Thrombosis

THROMBIN-JMI causes thrombosis if it enters the circulatory system. Apply topically. DO NOT INJECT.

5.3 Immunogenicity

Inhibitory antibodies may develop in patients and interfere with hemostasis. Monitor patients for abnormal coagulation laboratory values, bleeding, or thrombosis.

6 ADVERSE REACTIONS

The most common adverse reactions (incidence greater than or equal to 2%) following administration of THROMBIN-JMI were: hypersensitivity, bleeding, anemia, post-operative wound infection, thromboembolic events, hypotension, pyrexia, tachycardia and thrombocytopenia.

6.1 Clinical 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 safety assessment of THROMBIN-JMI is based primarily on the review of post marketing experience including three (3) randomized controlled clinical trials in which THROMBIN-JMI was used as a comparator and one (1) observational study. In these studies, the most common adverse reactions (incidence greater than or equal to 2%) following administration of THROMBIN-JMI were: hypersensitivity, bleeding, anemia, post-operative wound infection, thromboembolic events, hypotension, pyrexia, tachycardia and thrombocytopenia [see Clinical Studies (14) ].

6.2 Postmarketing Experience

The following serious adverse reactions have been identified during post approval use of THROMBIN-JMI: anaphylactic reactions, prolonged prothrombin time, prolonged activated partial thromboplastin time, disseminated intravascular coagulation, factor V deficiency, post-procedural hematoma, swelling and Staphylococcal wound infection. 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.

8 USE IN SPECIFIC POPULATIONS

8.1 Pregnancy

Animal reproduction studies have not been conducted with THROMBIN-JMI. It is also not known whether THROMBIN-JMI can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. THROMBIN-JMI should be given to a pregnant woman only if clearly needed.

8.2 Labor and Delivery

Information is unknown.

8.3 Nursing Mothers

It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when THROMBIN-JMI is administered to a nursing woman.

8.4 Pediatric Use

Safety and effectiveness in children have not been established

8.5 Geriatric Use

Clinical studies of THROMBIN-JMI did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy.

11 DESCRIPTION

THROMBIN-JMI, Thrombin, Topical (Bovine), is a protein substance produced through a conversion reaction in which prothrombin of bovine origin is activated by tissue thromboplastin of bovine origin in the presence of calcium chloride. It is supplied as a sterile powder that has been freeze-dried in the final container. Also contained in the preparation are mannitol and sodium chloride. Mannitol is included to make the dried product friable and more readily soluble. The product contains no preservative.

THROMBIN-JMI has been chromatographically purified and further processed by ultrafiltration. Analytical studies demonstrate the current manufacturing process’ capability to remove significant amounts of extraneous proteins, and result in a reduction of factor Va light chain content to levels below the limit of detection of semi-quantitative Western Blot assay (<92 ng/mL, when reconstituted as directed). The clinical significance of these findings is unknown.
