Label: PURIFIED CORTROPHIN GEL- repository corticotropin injection

Purified Cortrophin Gel is a porcine derived purified corticotropin (ACTH) in a sterile solution of gelatin. It is made up of a complex mixture of ACTH, ACTH related peptides and other porcine pituitary derived peptides.

The drug product is a sterile preparation containing 80 USP units per mL and it contains 0.5% phenol (as preservative), 15.0% gelatin (for prolonged activity), water for injection, and the pH is adjusted with hydrochloric acid and sodium hydroxide.

Purified Cortrophin Gel contains the porcine derived ACTH (1-39) with the following amino acid sequence:

Purified Cortrophin Gel is the anterior pituitary hormone which stimulates the functioning adrenal cortex to produce and secrete adrenocortical hormones.

Following administration of a single intramuscular injection of 80 Units of Cortrophin Gel to healthy volunteers (n=20) in an open label pharmacodynamic study, the median time (range) to reach peak cortisol concentration was 8 (3-12) hours. The baseline corrected geometric mean maximum (CV%) cortisol levels were 34.52 µg/dL (28.2%).

Purified Cortrophin Gel is indicated in the following disorders:

1. Rheumatic disorders:

 

As adjunctive therapy for short-term administration (to tide the patient over an acute episode or exacerbation) in:
Psoriatic arthritis.
Rheumatoid arthritis, including juvenile rheumatoid arthritis (selected cases may require low-dose maintenance therapy).
Ankylosing spondylitis.
Acute gouty arthritis.

2. Collagen diseases:

 

During an exacerbation or as maintenance therapy in selected cases of:
Systemic lupus erythematosus.
Systemic dermatomyositis (polymyositis).

3. Dermatologic diseases:

 

Severe erythema multiforme (Stevens-Johnson syndrome).
Severe psoriasis.

4. Allergic states:

 

Atopic dermatitis
Serum sickness.

5. Ophthalmic diseases:

 

Severe acute and chronic allergic and inflammatory processes involving the eye and its adnexa such as:
Allergic conjunctivitis.
Keratitis.
Iritis and iridocyclitis.
Diffuse posterior uveitis and choroiditis.
Optic neuritis.
Chorioretinitis.
Anterior segment inflammation.

6. Respiratory diseases:

 

Symptomatic sarcoidosis.

7. Edematous states:

 

To induce a diuresis or a remission of proteinuria in the nephrotic syndrome without uremia of the idiopathic type or that due to lupus erythematosus.

8. Nervous system:

 

Acute exacerbations of multiple sclerosis.

Purified Cortrophin Gel is contraindicated for intravenous administration.

Purified Cortrophin Gel is contraindicated in patients with scleroderma, osteoporosis, systemic fungal infections, ocular herpes simplex, recent surgery, history of or the presence of a peptic ulcer, congestive heart failure, hypertension, or sensitivity to proteins derived from porcine sources.

Purified Cortrophin Gel is contraindicated in patients with primary adrenocortical insufficiency or adrenocortical hyperfunction.

Chronic administration of corticotropin may lead to adverse effects which are not reversible.

This product should not be administered for treatment until adrenal responsiveness has been verified with the route of administration which will be utilized during treatment, intramuscularly or subcutaneously. A rise in urinary and plasma corticosteroid values provides direct evidence of a stimulatory effect. Although the action of corticotropin is similar to that of exogenous adrenocortical steroids the quantity of adrenocorticoid may be variable. In patients who receive prolonged corticotropin therapy the additional use of rapidly acting corticosteroids before, during and after an unusual stressful situation is indicated.

Masking Symptoms of Other Diseases

Corticotropin may only suppress symptoms and signs of chronic disease without altering the natural course of the disease.

Immunogenicity Potential

Purified Cortrophin Gel is immunogenic. Limited available data suggest that a patient may develop antibodies to Purified Cortrophin Gel after chronic administration and loss of endogenous ACTH and Purified Cortrophin Gel activity. Prolonged administration of Purified Cortrophin Gel may increase the risk of hypersensitivity reactions. Sensitivity to porcine protein should be considered before starting therapy and during the course of treatment should symptoms arise.

Ophthalmic Effects

Prolonged use of corticotropin may produce posterior subcapsular cataracts and glaucoma with possible damage to the optic nerves.

Infections

Corticotropin may mask some signs of infection, and new infections including those of the eye due to fungi or viruses may appear during its use. There may be decreased resistance and inability to localize infection when corticotropin is used.

Elevated Blood Pressure, Salt and Water Retention, and Hypokalemia

Corticotropin can cause elevation of blood pressure, salt and water retention, and increased excretion of potassium. Dietary salt restriction and potassium supplementation may be necessary. Corticotropin increases calcium excretion.

Vaccination

While on corticotropin therapy, patients should not be vaccinated against smallpox. Other immunization procedures should be undertaken with caution in patients who are receiving corticotropin, especially when high doses are administered because of the possible hazards of neurological complications and lack of antibody response.

Standard tests for verification of adrenal responsiveness to corticotropin may utilize as much as 80 units as a single injection or one or more injections of a lesser dosage. Verification tests should be performed prior to treatment with corticotropins. The test should utilize the route(s) of administration proposed for treatment. Following verification dosage should be individualized according to the disease under treatment and the general medical condition of each patient. Frequency and dose of the drug should be determined by considering severity of the disease, plasma and urine corticosteroid levels and the initial response of the patient. Only gradual change in dosage schedules should be attempted, after full drug effects have become apparent.

In the treatment of acute exacerbations of multiple sclerosis daily intramuscular doses of 80-120 units for 2-3 weeks.

The chronic administration of more than 40 units daily may be associated with uncontrollable adverse effects.

When reduction in dosage is indicated this should be accomplished gradually by either reducing the amount of each injection, or administering injections at longer intervals, or by a combination of both of the above. During reduction of dosage, careful consideration should be given to the disease being treated, the general medical condition of the patient and the duration over which corticotropin was administered.

This product may be administered subcutaneously or intramuscularly.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit.

Purified Cortrophin Gel is supplied sterile in 1 mL and 5 mL multiple-dose vials.

Store Purified Cortrophin Gel vials refrigerated at 2° to 8°C (36° to 46°F). After first use discard Purified Cortrophin Gel vials per the table below. Write the revised expiration date in the space provided on the carton labeling.
