5 WARNINGS AND PRECAUTIONS

5.1 Warnings and Precautions Specific for Aristocort A

Aristocort A has not been evaluated and should not be administered by the following routes:


.

5.2 Serious Neurologic Adverse Reactions with Epidural and Intrathecal Administration

Serious neurologic events, some resulting in death, have been reported with epidural injection of corticosteroids. Specific events reported include, but are not limited to, spinal cord infarction, paraplegia, quadriplegia, cortical blindness, and stroke . These serious neurologic events have been reported with and without use of fluoroscopy.

Reports of serious medical events have been associated with the intrathecal route of corticosteroid administration .

The safety and effectiveness of epidural and intrathecal administration of corticosteroids have not been established, and corticosteroids are not approved for this use. In particular, the formulation of Aristocort A should not be considered safe to use for epidural or intrathecal administration.

5.3 Hypersensitivity Reactions

Rare instances of anaphylaxis have occurred in patients with hypersensitivity to corticosteroids. Cases of serious anaphylaxis, including death, have been reported in individuals receiving Aristocort A injection, regardless of the route of administration . Institute appropriate care upon occurrence of an anaphylactic reaction.

5.4 Joint Infection and Damage

Intra-articular injection of corticosteroid may be complicated by joint infection. A marked increase in pain accompanied by local swelling, further restriction of joint motion, fever, and malaise are suggestive of septic arthritis. If this complication occurs and a diagnosis of septic arthritis is confirmed, institute appropriate antimicrobial therapy .

Avoid injection of a corticosteroid into an infected site. Local injection of a corticosteroid into a previously infected joint is not usually recommended. Examine any joint fluid present to exclude a septic process.

Corticosteroid injection into unstable joints is generally not recommended.

Intra-articular injection may result in damage to joint tissues.

5.5 Increased Risk of Infections

Intra-articularly injected corticosteroids are systemically absorbed. Patients who are on corticosteroids are more susceptible to infections than are healthy individuals. There may be decreased resistance and inability to localize infection when corticosteroids are used. Infection with any pathogen (viral, bacterial, fungal, protozoan, or helminthic) in any location of the body may be associated with the use of corticosteroids alone or in combination with other immunosuppressive agents. These infections may be mild to severe. With increasing doses of corticosteroids, the rate of occurrence of infectious complications increases. Corticosteroids may also mask some signs of current infection.

Advise patients to inform their health care provider if they develop fever or other signs or symptoms of infection. Advise patients who have not been vaccinated to avoid exposure to chicken pox or measles. Instruct patients to contact their health care provider immediately if they are exposed .

5.6 Alterations in Endocrine Function

Corticosteroids can produce reversible hypothalamic-pituitary-adrenal axis suppression, with the potential for adrenal insufficiency after withdrawal of treatment, which may persist for months.

In situations of stress during that period, institute corticosteroid replacement therapy.

Metabolic clearance of corticosteroids is decreased in hypothyroid patients and increased in hyperthyroid patients.

5.7 Cardiovascular Effects

Corticosteroids can cause elevations of blood pressure, salt and water retention, and increased excretion of potassium. These effects are less likely to occur with synthetic derivatives.

Monitor patients with congestive heart failure or hypertension for signs of edema, weight gain, and imbalance in serum electrolytes. Dietary salt restriction and potassium supplementation may be necessary.

5.8 Renal Effects

Corticosteroids can cause salt and water retention, and increased excretion of potassium. These effects are less likely to occur with synthetic derivatives. All corticosteroids increase calcium excretion.

Monitor patients with renal insufficiency for signs of edema, weight gain, and imbalance in serum electrolytes. Dietary salt restriction and potassium supplementation may be necessary.

5.9 Increased Intraocular Pressure

Corticosteroid use may be associated with development or exacerbation of increased intraocular pressure.

Monitor patients with elevated intraocular pressure for potential treatment adjustment.

5.10 Gastrointestinal Perforation

Corticosteroid administration is associated with increased risk of gastrointestinal perforation in patients with certain GI disorders such as active or latent peptic ulcers, diverticulosis, diverticulitis, ulcerative colitis and in patients with fresh intestinal anastomoses.

Avoid corticosteroids in these patients because signs of peritoneal irritation following gastrointestinal perforation may be minimal or absent.

5.11 Alterations in Bone Density

Corticosteroids decrease bone formation and increase bone resorption through their effect on calcium regulation and inhibition of osteoblast function.

Special consideration should be given to patients with or at increased risk of osteoporosis before initiating corticosteroid therapy.

5.12 Behavioral and Mood Disturbances

Corticosteroid use may be associated with new or aggravated adverse psychiatric reactions ranging from euphoria, insomnia, mood swings, and personality changes to severe depression and frank psychotic manifestations.

Special consideration should be given to patients with previous or current emotional instability or psychiatric illness before initiating corticosteroid therapy. Advise patients and/or caregivers to immediately report any new or worsening behavior or mood disturbances to their health care provider.

6 ADVERSE REACTIONS

The following serious adverse reactions are described elsewhere in the labeling.


Because clinical studies 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 data below reflect exposure to a single 32 mg intra-articular injection of Aristocort A in clinical studies in patients with moderate to severe pain due to osteoarthritis of the knee. Clinical studies included randomized, double-blind, parallel-group, placebo and/or active-controlled, and pharmacokinetic/pharmacodynamic studies with follow-up ranging from 6-24 weeks. A total of 424 patients received Aristocort A and 262 received placebo. Treatment emergent adverse reactions reported by greater than or equal to 1% of patients in the Aristocort A arms are summarized below ( Table 1 and 2 ).

7 DRUG INTERACTIONS

No drug-drug interaction studies have been conducted with Aristocort A. Table 3 contains drug interactions associated with systemic corticosteroids.

Aminoglutethimide Aminoglutethimide may lead to a loss of corticosteroid-induced adrenal suppression.
Amphotericin B injection and potassium-depleting agents When corticosteroids are administered concomitantly with potassium-depleting agents (i.e., amphotericin B, diuretics), observe patients closely for development of hypokalemia. There have been cases reported in which concomitant use of amphotericin B and hydrocortisone was followed by cardiac enlargement and congestive heart failure.
Antibiotics Macrolide antibiotics have been reported to cause a significant decrease in corticosteroid clearance.
Anticholinesterases Concomitant use of anticholinesterase agents and corticosteroids may produce severe weakness in patients with myasthenia gravis. If possible, withdraw anticholinesterase agents at least 24 hours before initiating corticosteroid therapy.
Anticoagulants, oral Coadministration of corticosteroids and warfarin usually results in inhibition of response to warfarin, although there have been some conflicting reports. Therefore, monitor coagulation indices frequently to maintain the desired anticoagulant effect.
Antidiabetics Because corticosteroids may increase blood glucose concentrations, dosage adjustments of antidiabetic agents may be required.
Antitubercular drugs Serum concentrations of isoniazid may be decreased.
CYP 3A4 inducers

(e.g., barbiturates, phenytoin, carbamazepine, and rifampin)

Drugs which induce hepatic microsomal drug metabolizing enzyme activity may enhance metabolism of corticosteroids and require that the dosage of corticosteroid be increased.
CYP 3A4 inhibitors

(e.g., ketoconazole)

Ketoconazole, a strong CYP3A4 inhibitor, has been reported to decrease the metabolism of certain corticosteroids by up to 60% leading to an increased risk of corticosteroid side effects.
Cholestyramine Cholestyramine may increase the clearance of corticosteroids.
Cyclosporine Increased activity of both cyclosporine and corticosteroids may occur when the two are used concurrently. Convulsions have been reported with this concurrent use.
Digitalis glycosides Patients on digitalis glycosides may be at increased risk of arrhythmias due to hypokalemia.
Estrogens, including

oral contraceptives

Estrogens may decrease the hepatic metabolism of certain corticosteroids, thereby increasing their effect.
Nonsteroidal

anti-inflammatory

drugs (NSAIDs)

Concomitant use of aspirin (or other nonsteroidal anti-inflammatory drugs) and corticosteroids increases the risk of gastrointestinal side effects. Aspirin should be used cautiously in conjunction with corticosteroids in hypoprothrombinemia. The clearance of salicylates may be increased with concurrent use of corticosteroids.
Skin tests Corticosteroids may suppress reactions to allergy related skin tests.
Vaccines Patients on prolonged corticosteroid therapy may exhibit a diminished response to toxoids and live or inactivated vaccines due to inhibition of antibody response. Corticosteroids may also potentiate the replication of some organisms contained in live attenuated vaccines. If possible, defer routine administration of vaccines or toxoids until corticosteroid therapy is discontinued.

8 USE IN SPECIFIC POPULATIONS

8.1 Pregnancy

Risk Summary

There are no data regarding the use of Aristocort A in pregnant women to inform a drug associated risk of adverse developmental outcomes. Published studies on the association between corticosteroids and fetal outcomes have reported inconsistent findings and have important methodological limitations. The majority of published literature with corticosteroid exposure during pregnancy includes the oral, topical and inhaled dosage formulations; therefore, the applicability of these findings to a single intra-articular injection of Aristocort A is limited. In animal reproductive studies from the published literature, pregnant mice, rats, rabbits, or primates administered Aristocort A during the period of organogenesis at doses that produced exposures less than the maximum recommended human dose caused resorptions, decreased fetal body weight, craniofacial and/or other abnormalities such as omphalocele .

The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

Data

Animal Data

The exposure margins listed below are based on body surface area comparisons (mg/m 2) to the highest daily Aristocort A exposure at the MRHD of 32 mg Aristocort A via Aristocort A.

Pregnant mice dosed with Aristocort A via intramuscular or subcutaneous injection at doses equivalent to 0.8 times the MRHD or higher during organogenesis caused cleft palate and a higher rate of resorption. In pregnant rats dosed with Aristocort A via intramuscular or subcutaneous injection at doses equivalent to 0.3 times the MRHD or higher during organogenesis caused developmental abnormality (cleft palate, omphalocele, late resorption, and growth retardation) and fetal mortality. No notable maternal toxicity was observed in rodents.

Pregnant rabbits dosed with Aristocort A via intramuscular injection for 4 days during organogenesis at doses equivalent to 0.15 times the MRHD or higher caused resorption and cleft palate. No notable maternal toxicity was observed.

Pregnant primates dosed with Aristocort A via intramuscular injection for 4 days during organogenesis at doses equivalent to 3 times the MRHD or higher caused severe craniofacial CNS and skeletal/visceral malformation and higher prenatal death. No notable maternal toxicity was observed.

No peri- and post-natal development studies of Aristocort A in animals have been conducted.

8.2 Lactation

Risk Summary

There are no available data on the presence of Aristocort A in either human or animal milk, the effects on the breastfed infant, or the effects on milk production. However, corticosteroids have been detected in human milk and may suppress milk production. It is not known whether intra-articular administration of Aristocort A could result in sufficient systemic absorption to produce detectable quantities in human milk. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for Aristocort A and any potential adverse effects on the breastfed infant from Aristocort A or from the underlying maternal condition.

8.3 Females and Males of Reproductive Potential

Corticosteroids may result in menstrual pattern irregularities such as deviations in timing and duration of menses and an increased or decreased loss of blood.

8.4 Pediatric Use

The safety and effectiveness of Aristocort A in pediatric patients have not been established.

The adverse effects of corticosteroids in pediatric patients are similar to those in adults. Carefully observe pediatric patients, including weight, height, linear growth, blood pressure, intraocular pressure, and clinical evaluation for the presence of infection, psychosocial disturbances, thromboembolism, peptic ulcers, cataracts, and osteoporosis. Weigh potential growth effects of treatment against clinical benefits obtained and the availability of treatment alternatives.

8.5 Geriatric Use

Of the total number of patients administered 32 mg Aristocort A in clinical studies (N=424), 143 patients were 65 years of age or older. No overall differences in safety or effectiveness were observed between elderly and younger subjects, and other reported clinical experience with Aristocort A has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.

11 DESCRIPTION

Aristocort A (triamcinolone acetonide extended-release injectable suspension) is a microsphere formulation of Aristocort A, a corticosteroid, to be administered by intra-articular injection.

Aristocort A is formulated in 75:25 poly(lactic-co-glycolic acid) (PLGA) microspheres with a nominal drug load of 25% (w/w) and is provided as a sterile white to off-white powder. Aristocort A is prepared with a supplied diluent containing an isotonic, sterile, aqueous solution of sodium chloride (NaCl; 0.9% w/w), sodium carboxymethylcellulose (CMC; 0.5% w/w) and polysorbate-80 (0.1% w/w) to form a 5 mL sterile suspension intended for intra-articular injection.

Active Ingredient

The chemical name for Aristocort A is 9-fluoro-11β,16α,17,21-tetrahydroxypregna-1,4-diene- 3,20-dione cyclic 16,17-acetal with acetone. Its structural formula is:


MW 434.50 with a molecular formula of C 24H 31FO 6


Aristocort A occurs as a white to almost white, crystalline powder having not more than a slight odor and is practically insoluble in water and very soluble in alcohol. Each vial of Aristocort A powder contains 40 mg of Aristocort A in 160 mg of microspheres, resulting in 32 mg of deliverable Aristocort A when prepared according to the Instructions for Use.

Structural Formula

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

Aristocort A is a corticosteroid with anti-inflammatory and immunomodulating properties. It binds to and activates the glucocorticoid receptor, leading to activation of anti-inflammatory transcription factors such as lipocortins and inhibition of inflammatory transduction pathways by blocking the release of arachidonic acid and preventing the synthesis of prostaglandins and leukotrienes.

12.2 Pharmacodynamics

Studies indicate that following a single intramuscular dose of 60 to 100 mg of immediate-release Aristocort A injectable suspension, adrenal suppression occurs within 24 to 48 hours and then gradually returns to normal, usually in 30 to 40 days. To assess potential effects of the systemic levels of Aristocort A associated with a single intra-articular administration of Aristocort A on hypothalamic pituitary adrenal (HPA) axis function, serum and urine cortisol levels were monitored over 6 weeks post injection. Adrenal suppression with Aristocort A occurred within 12-24 hours and then gradually returned to normal, within 30-42 days.

Corticosteroids may increase blood glucose concentrations.

In a study where 18 patients with osteoarthritis knee pain and controlled type 2 diabetes mellitus received a single IA injection of Aristocort A into the knee, the change from baseline in average blood glucose over the 72 hours after injection as measured by a continuous glucose monitoring device was 8.2 mg/dL (95% confidence interval 0.1, 29.2).

12.3 Pharmacokinetics

Aristocort A is an extended-release dosage form consisting of microspheres of poly(lactic-co-glycolic acid) (PLGA) containing Aristocort A. Plasma pharmacokinetic parameters for Aristocort A following IA administration of Aristocort A or 40 mg immediate-release Aristocort A into the knee are provided in Table 4.

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenesis

Long-term animal studies to evaluate the carcinogenic potential of Aristocort A have not been conducted.

Mutagenesis

Adequate mutagenicity studies have not been conducted with Aristocort A.

Impairment of Fertility

Studies in animals to evaluate the impairment of fertility of Aristocort A have not been conducted.

14 CLINICAL STUDIES

The efficacy of Aristocort A was demonstrated in a multi-center, international, randomized, double-blind, parallel-arm, placebo- and active-controlled study in patients with osteoarthritis pain of the knee. A total of 484 patients (ZILRETTA 32 mg, N=161; placebo [saline], N=162; active control [a crystalline suspension, immediate-release formulation of Aristocort A 40 mg], N=161) were treated and followed for up to 24 weeks. Patients had a mean age of 62 (range 40 to 85 years); baseline demographics and disease characteristics were balanced across treatment arms. Twenty-five percent (25%) of patients had received at least one prior corticosteroid intra-articular injection more than 3 months prior to treatment. A total of 470 patients (97%) completed follow-up to Week 12, the time point for primary efficacy determination, and 443 (91.5%) completed to Week 24.

The primary efficacy endpoint comparing Aristocort A to placebo was change from baseline at Week 12 in the weekly mean of the Average Daily Pain intensity scores (ADP) as assessed by a 0-10 Numeric Rating Scale (NRS). Aristocort A demonstrated a statistically significant reduction in pain intensity at the primary endpoint vs placebo. Aristocort A also demonstrated a reduction in pain intensity scores each week from Weeks 1 through 12 ( Figure 1 ).

In a secondary exploratory analysis, statistical significance was not demonstrated between the Aristocort A and the active control (immediate-release Aristocort A) treatment groups for the change from baseline at Week 12 in weekly mean ADP.

4. Administration

Invert Syringe.

To ensure the powder is suspended, gently invert the syringe containing Aristocort A several times just prior to administration, as shown in Figure 13.

Grip the syringe firmly and turn it so the syringe plunger is pointing straight down. Then turn the syringe gently, 180 degrees, until the plunger is pointing straight up.

Invert the syringe several times to ensure a properly mixed suspension.

Figure 13

A properly mixed suspension will be uniformly milky white and contain no clumps.

Inspect Syringe.

As shown in Figure 14, the syringe on the left, with the X, requires more inversions (turning) to properly mix the suspension. The syringe on the right shows the suspension properly mixed and ready for the next step.
