Across FDA labelling, products containing TRIAMCINOLONE ACETONIDE EXTENDED-RELEASE INJECTABLE SUSPENSION are most often described in connection with: indicated intra-articular, management osteoarthritis, safety repeat, administration zilretta, triamcinolone acetonide, extended-release injectable, synthetic corticosteroid, knee limitation. Wording differs between labels, and the full indications section on this page takes precedence when it is present.

1 INDICATIONS AND USAGE ZILRETTA (triamcinolone acetonide extended-release injectable suspension) is indicated as an intra-articular injection for the management of osteoarthritis pain of the knee. ZILRETTA is an extended-release synthetic corticosteroid indicated as an intra-articular injection for the management of osteoarthritis pain of the knee. ( 1 ) Limitation of Use The efficacy and safety of repeat administration of ZILRETTA have not been demonstrated. ( 2.1 ) Limitation of Use The efficacy and safety of repeat administration of ZILRETTA have not been demonstrated. [see Dosage and Administration (2.1) ] .

2 DOSAGE AND ADMINISTRATION 32 mg (5 mL) administered as a single intra-articular injection in the knee. ( 2.1 ) See Instructions for Use (IFU) for instructions on reconstitution of ZILRETTA with the supplied diluent. ( 2.2 ) It is normal for some residue to be left behind on the vial walls after withdrawing the suspension. ( 2.2 ) ZILRETTA is NOT substitutable with other formulations of injectable triamcinolone acetonide. ( 2.3 ) 2.1 Important Dosage and Administration Information ZILRETTA is administered as a single intra-articular extended-release injection of triamcinolone acetonide, to deliver 32 mg (5 mL). ZILRETTA is for intra-articular use only. Do NOT administer by the following routes: epidural, intrathecal, intravenous, intraocular, intramuscular, intradermal, subcutaneous. ZILRETTA is not suitable for use in small joints, such as the hand. The efficacy and safety of repeat administration of ZILRETTA have not been demonstrated [see Adverse Reactions (6) and Nonclinical Toxicology (13.2) ] . The efficacy and safety of ZILRETTA for management of osteoarthritis pain of shoulder and hip have not been evaluated. 2.2 Preparation and Administration of Intra-Articular Suspension Refer to the Instructions for Use for directions on the preparation and administration of ZILRETTA. ZILRETTA is supplied as a single-dose kit containing a vial of ZILRETTA microsphere powder, a vial of sterile diluent, and a sterile vial adapter. ZILRETTA must be prepared using the diluent supplied in the kit. Preparation of ZILRETTA requires close attention to the Instructions for Use to ensure successful administration. Use proper aseptic technique throughout the dose preparation and administration procedure. ZILRETTA is a suspension product and it is normal for some residue to be left behind on the vial walls after withdrawing the contents. Promptly inject ZILRETTA after preparation to avoid settling of the suspension. If needed, the ZILRETTA suspension can be stored in the vial for up to 4 hours at ambient conditions. Gently swirl the vial to resuspend any of the settled microspheres prior to preparing the syringe for injection. The usual technique for intra-articular injection should be followed. Aspiration of synovial fluid may be performed based on clinical judgment prior to administration of ZILRETTA. 2.3 Non-Interchangeability with Other Formulations of Triamcinolone Acetonide for Intra-articular Use ZILRETTA is NOT substitutable with other formulations of injectable triamcinolone acetonide.

Patients with hypersensitivity to triamcinolone acetonide or any component of the product. ( 4 )

6 ADVERSE REACTIONS The following serious adverse reactions are described elsewhere in the labeling. Serious Neurologic Adverse Reactions with Epidural and Intrathecal Administration [see Warnings and Precautions (5.2) ] Hypersensitivity Reactions [see Warnings and Precautions (5.3) ] Joint Infection and Damage [see Warnings and Precautions (5.4) ] Increased Risk of Infections [see Warnings and Precautions (5.5) ] Alterations in Endocrine Function [see Warnings and Precautions (5.6) ] Cardiovascular Effects [see Warnings and Precautions (5.7) ] Renal Effects [see Warnings and Precautions (5.8) ] Increased Intraocular Pressure [see Warnings and Precautions (5.9) ] Gastrointestinal Perforation [see Warnings and Precautions (5.10) ] Alternations in Bone Density [see Warnings and Precautions (5.11) ] Behavioral and Mood Disturbances [see Warnings and Precautions (5.12) ] Most commonly reported adverse reactions (incidence ≥1%) in clinical studies include sinusitis, cough, and contusions.

The data below reflect exposure to a single 32 mg intra-articular injection of ZILRETTA 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 ZILRETTA and 262 received placebo. Treatment emergent adverse reactions reported by greater than or equal to 1% of patients in the ZILRETTA arms are summarized below ( Table 1 and 2 ). Overall, the incidence and nature of adverse reactions was similar to that observed with placebo. Table 1: Most Commonly Reported Treatment-Emergent Adverse Reactions with ZILRETTA (Incidence ≥1%) in Patients with Osteoarthritis of the Knee Preferred Term (MedDRA) ZILRETTA (N=424) Placebo (N=262) Sinusitis 2% 1% Cough 2% 1% Contusions 2% 1% Table 2: Most Commonly Reported Treatment-Emergent Injected Knee Adverse Reactions with ZILRETTA (Incidence ≥1%) in Patients with Osteoarthritis of the Knee Preferred Term (MedDRA) ZILRETTA (N=424) Placebo (N=262) Joint Swelling 3% 2% Contusions 2% 1% The safety of repeat administration of ZILRETTA was evaluated in a multicenter, open-label, single-arm study in patients with osteoarthritis pain of the knee. A total of 179 patients received a repeat injection on or after Week 12 (median 16.6 weeks) and were followed for 52 weeks from the initial injection. As assessed by adverse event rates for the periods of baseline to second dose and second dose to the comparable period after the second dose, there were higher rates of reported mild to moderate arthralgia after the second dose (16%) than after the first dose (6%). The data from this study are insufficient to fully characterize the safety of repeat administration of ZILRETTA. [See also Nonclinical Toxicology (13.2) ]. 6.2 Post-marketing Experience The following adverse reactions, presented alphabetically by body system, have been identified during post-approval use of ZILRETTA.
