TUBERSOL®
Tuberculin Purified Protein Derivative
(Mantoux)
Diagnostic
Antigen (Aid in the detection of infection with Mycobacterium tuberculosis)
FOR INTRADERMAL USE
Polysorbate 80 Stabilized Solution of Tuberculin Purified Protein Derivative for Tuberculin Testing in Humans
TUBERSOL®, Tuberculin Purified Protein Derivative (Mantoux) (PPD) (1) for intradermal tuberculin testing is prepared from a large Master Batch Connaught Tuberculin (CT68) (2) and is a cell-free purified protein fraction obtained from a human strain of Mycobacterium tuberculosis grown on a protein-free synthetic medium and inactivated. (2) The use of a standard preparation derived from a single batch (CT68) has been adopted in order to eliminate batch to batch variation by the same manufacturer. (2)
TUBERSOL is a clear, colorless liquid.
TUBERSOL contains:
| Purified protein derivative of M. tuberculosis | 5 TU per 0.1 mL |
| Polysorbate 80 | 0.0006% |
| Phenol | 0.22% to 0.35% w/v |
in sterile isotonic phosphate buffered saline.
Before release, each successive lot is tested for potency in comparison with the US Standard Tuberculin PPD-S. (3)
Independent studies conducted by the US Public Health Service in humans have determined the amount of CT68 in stabilized solution necessary (4) (5) (6) to produce bio-equivalency with Tuberculin PPD-S (in phosphate buffer without polysorbate 80) using 5 US units (TU) Tuberculin PPD-S as the standard.

TUBERSOL, Tuberculin Purified Protein Derivative (Mantoux), is indicated to aid diagnosis of tuberculosis infection (TB) in persons at increased risk of developing active disease.
The Centers for Disease Control and Prevention (CDC) have published guidelines regarding populations that would benefit from tuberculin skin testing (TST). Current recommendations can be accessed at: http://www.cdc.gov/tb/publications/factsheets/testing.htm.
Previous BCG vaccination is not a contraindication to tuberculin testing. The skin-test results of BCG vaccinated persons can be used to support or exclude the diagnosis of TB infection. However, an FDA-approved interferon gamma release assay is preferred over tuberculin skin test for persons 5 years of age and older who were previously vaccinated with BCG. (9)
Five (5) tuberculin units (TU) per test dose of 0.1 mL is the standard strength used for intradermal (Mantoux) testing.
TUBERSOL is indicated for intradermal injection only. Do not inject intravenously, intramuscularly, or subcutaneously. If subcutaneous injection occurs, the test cannot be interpreted.
Inspect for extraneous particulate matter and/or discoloration before use. If these conditions exist, do not administer the product.
Use a separate syringe and needle for each injection.
The following procedure is recommended for performing the Mantoux test:
In the event of an improperly performed injection (ie, no bleb formed), repeat the test immediately at another site, at least 2 inches from the first site and circle the second injection site as an indication that this is the site to be read.
Inform the patient of the need to return for the reading of the test by a trained health professional. Self-reading may be inaccurate and is strongly discouraged.
The skin test should be read by a trained health professional 48 to 72 hours after administration of TUBERSOL. Skin test sensitivity is indicated by induration only; redness should not be measured.
Measure the diameter of induration transversely to the long axis of the forearm and record the measurement in millimetres (including 0 mm). (8) The tip of a ballpoint pen, gently pushed at a 45° angle toward the site of injection, will stop at the edge of induration.
Also record presence and size (if present) of necrosis and edema, although these are not used in the interpretation of the test.
Tuberculin reactivity may indicate latent infection, prior infection and/or disease with M. tuberculosis and does not necessarily indicate the presence of active tuberculous disease. Persons showing positive tuberculin reactions should be considered positive by current public health guidelines and referred for further medical evaluation. (8) (10) The repeated testing of uninfected persons does not sensitize them to TUBERSOL. (7) (8) (10) (13)
The significance of induration measurements in diagnosing latent TB infection must be considered in terms of the patient's history and the risk of developing active TB disease as indicated in Table 1. (10)
Table 1: Criteria for tuberculin positivity, by risk
group
| Reaction ≥ 5 mm of Induration | Reaction ≥ 10 mm of Induration | Reaction ≥ 15 mm of Induration |
| HIV-positive persons Recent contacts of tuberculosis (TB) case patients Fibrotic changes on chest radiograph consistent with prior TB Patients with organ transplants and other immunosuppressed patients (receiving the equivalent of > 15 mg/d of prednisone for 1 month or more)* |
Recent immigrants (i.e., within the last 5 yrs) from high prevalence countries Injection drug users Residents or employees† of the following high-risk congregate settings: prisons and jails, nursing homes and other long-term facilities for the elderly, hospitals and other health care facilities, residential facilities for patients with acquired immunodeficiency syndrome (AIDS) and homeless shelters Mycobacteriology laboratory personnel Persons with the following clinical conditions that place them at high risk: silicosis, diabetes mellitus, chronic renal failure, some hematologic disorders (e.g., leukemias and lymphomas), other specific malignancies (e.g., carcinoma of the head or neck and lung), weight loss of ≥ 10% of ideal body weight, gastrectomy and jejunoileal bypass Children younger than 4 yrs of age or infants, children, and adolescents exposed to adults at high-risk |
Persons with no risk factors for TB |
| * Risk of TB in patients treated with
corticosteroids increases with higher dose and longer duration. †For persons who are otherwise at low risk and are tested at the start of employment, a reaction of ≥ 15 mm induration is considered positive. |
||
A TST conversion is defined as an increase of ≥ 10 mm of induration within a 2-year period, regardless of age. (10)
The possibility should be considered that the skin test sensitivity may also be due to a previous contact with atypical mycobacteria or previous BCG vaccination. (8) (10) (13)
An individual who does not show a positive reaction to 5 TU on the first test, but is suspected of being TB positive, may be retested with 5 TU. (See Booster Effect and Two-Step Testing) Any individual who does not show a positive reaction to an initial injection of 5 TU, or a second test with 5 TU may be considered as tuberculin negative.
False positive tuberculin reactions can occur in individuals who have been infected with other mycobacteria, including vaccination with BCG. (8) (13) However, a diagnosis of M. tuberculosis infection and the use of preventive therapy should be considered for any BCG-vaccinated person who has a positive TST reaction, especially if the person has been, or is, at increased risk of acquiring TB infection. (See INDICATIONS AND USAGE) (15) (16)
Not all infected persons will have a delayed hypersensitivity reaction to a tuberculin test.
In those who are elderly or those who are being tested for the first time, reactions may develop slowly and may not peak until after 72 hours.
Since tuberculin sensitivity may take up to 8 weeks to develop following exposure to M. tuberculosis (See Mechanism of Action), persons who have a negative tuberculin test < 8 weeks following possible TB exposure should be retested ≥ 8-10 weeks following the last known or suspected exposure. (17)
Impaired or attenuated cell mediated immunity (CMI) can potentially cause a false negative tuberculin reaction. Many factors have been reported to cause a decreased ability to respond to the tuberculin test in the presence of tuberculous infection including viral infections (e.g., measles, mumps, chickenpox and HIV), live virus vaccinations (e.g., measles, mumps, rubella, oral polio and yellow fever), overwhelming tuberculosis, other bacterial infections, leukemia, sarcoidosis, fungal infections, metabolic derangements, low protein states, diseases affecting lymphoid organs, drugs (corticosteroids and many other immunosuppressive agents), and malignancy or stress. (8) (18) (19) A TST should be deferred for patients with major viral infections or live-virus vaccination in the past month. Persons with the common cold may be tuberculin tested.
Because TST results in HIV-infected individuals are less reliable as CD4 counts decline, screening should be completed as early as possible after HIV-infection occurs. (19)
If tuberculin testing will be conducted at regular intervals, for instance among health-care workers or prison workers, two-step testing should be performed as a baseline to avoid interpreting a booster effect as a tuberculin conversion. If the first test showed either no reaction or a small reaction, the second test should be performed one to four weeks later. Both tests should be read and recorded at 48 to 72 hours. Patients with a second tuberculin test (booster) response of ≥ 10 mm should be considered to have experienced past TB infection. (15) (20)
Persons who do not boost when given repeat tests at one week, but whose tuberculin reactions change to positive after one year, should be considered to have newly acquired tuberculosis infection and managed accordingly. (7)

Induration at the TUBERSOL injection site is the expected reaction for a positive skin test. (See Interpretation of the Test)
The information pertaining to adverse events has been compiled from historical clinical studies and post-marketing experience with TUBERSOL.
Injection site pain, injection site pruritus and injection site discomfort.
Injection site erythema or injection site rash (without induration) occurring within 12 hours of testing. These reactions do not indicate TB infection.
Injection site hemorrhage and injection site hematoma up to three days after the administration of the test.
Injection site vesicles, injection site ulcer or injection site necrosis in highly sensitive persons.
Injection site scar as a result of strongly positive reactions.
Pyrexia
Hypersensitivity, including anaphylaxis/anaphylactic reactions, angiodema, urticaria
Stridor, dyspnea
Rash, generalized rash
Presyncope, syncope (including syncope associated with tonic-clonic movements and other seizure-like activity) sometimes resulting in transient loss of consciousness with injury
To report SUSPECTED ADVERSE REACTIONS, contact the Pharmacovigilance Department, Sanofi Pasteur Inc., Discovery Drive, Swiftwater, PA 18370 or call 1-800-822-2463 (1-800-VACCINE) or Food and Drug Administration (FDA) MEDWATCH Program at 1-800-332-1088 and www.fda.gov/medwatch.
Reactivity to the test may be depressed or suppressed in persons who are receiving corticosteroids or immunosuppressive agents. (8)
Reactivity to TUBERSOL may be temporarily depressed by certain live virus vaccines (measles, mumps, rubella, oral polio, yellow fever, and varicella). If a parenteral live attenuated virus vaccine has been administered recently, tuberculin testing should be delayed for > 1 month after vaccination. (8) (12) (See Interpretation of the Test)
When tuberculin screening is required at the same time as a measles-containing vaccine or other parenteral live attenuated virus vaccine, simultaneous administration of TUBERSOL and the vaccine at separate sites is the preferred option.
Allergic reactions may occur following the use of TUBERSOL even in persons with no prior history of hypersensitivity to the product components. (11) Epinephrine injection (1:1,000) and other appropriate agents used for the control of immediate allergic reactions must be immediately available.
Syncope (fainting) can occur in association with administration of injectable medicines, including TUBERSOL. Procedures should be in place to avoid falling injury and to restore cerebral perfusion following syncope.
False positive or false negative tuberculin skin test reactions may occur in some individuals. (See Interpretation of the Test)
False positive tuberculin reaction tests occur in individuals who have been infected with other mycobacteria, including vaccination with BCG.
Not all infected persons will have a delayed hypersensitivity reaction to a tuberculin test.
Many factors have been reported to cause a decreased ability to respond to the tuberculin test in the presence of tuberculous infection. (See Interpretation of the Test)
TUBERSOL has not been evaluated for its carcinogenic or mutagenic potentials or impairment of fertility.
Animal reproduction studies have not been conducted with TUBERSOL. It is also not known whether TUBERSOL can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. TUBERSOL should be given to a pregnant woman only if clearly needed.
It is not known whether TUBERSOL is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when TUBERSOL is administered to a nursing woman.
There is no age contraindication to tuberculin skin testing of infants. Because their immune systems are immature, many infants < 6 weeks of age who are infected with M. tuberculosis do not react to tuberculin tests. (13) (See Interpretation of the Test)
Clinical studies of TUBERSOL did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects.

The sensitization following infection with mycobacteria occurs primarily in the regional lymph nodes. Small lymphocytes (T lymphocytes) proliferate in response to the antigenic stimulus to give rise to specifically sensitized lymphocytes. After 3-8 weeks, these lymphocytes enter the blood stream and circulate for years. (7) Subsequent restimulation of these sensitized lymphocytes with the same or a similar antigen, such as the intradermal injection of TUBERSOL, evokes a local reaction mediated by these cells. (8)
Characteristically, delayed hypersensitivity reactions to tuberculin begin at 5 to 6 hours, are maximal at 48 to 72 hours and subside over a period of days. The resultant immune response consists of induration due to cell infiltration and occasionally vesiculation and necrosis. Clinically, a delayed hypersensitivity reaction to tuberculin is a manifestation of previous infection with M tuberculosis or a variety of non-tuberculosis bacteria. In most cases sensitization is induced by natural mycobacterial infection or by vaccination with BCG Vaccine.

Prior to administration of TUBERSOL, the patient's current health status and medical history should be reviewed. The physician should review the patient's immunization history for possible sensitivity to components of TUBERSOL.
The health-care provider should inform the patient of the need to return for the reading of the test. Self-reading of the test has been shown to be inaccurate and unreliable.
The health-care provider should give the patient a permanent personal record. In addition, it is essential that the health professional record the testing history in the permanent medical record of each patient. This permanent office record should contain the name of the product, date given, dose, manufacturer and lot number, as well as the test result in millimeters of induration (including 0 mm, if appropriate). Reporting results only as negative or positive is not satisfactory.
