New Formulation NCT00071227 ↗ Eye Injections of Triamcinolone Acetonide for Retinal Blood Vessel Disorders Completed National Eye Institute (NEI) Phase 1 2003-10-15 This study will evaluate the safety and effectiveness of a new formulation of triamcinolone acetonide for the treatment of retinal blood vessel disorders. Triamcinolone is a steroid drug that decreases inflammation and scarring and is routinely used to treat eye inflammation or swelling. The commercially available form of this drug is associated with potentially harmful side effects thought to be due to preservatives in the preparation. This study will use a formulation that does not contain these potentially harmful preservatives. Preliminary findings from other studies suggest that injection of steroids in the eye can reduce retinal thickening and improve vision. However, they may also cause mild discomfort and lead to vision-threatening conditions. The effects of the drug on the conditions under study in this protocol are not known. Patients with the following conditions involving disorders of retinal blood vessels may be eligible for this study: - Choroidal neovascularization associated with age-related macular degeneration (50 years of age and older) - Macular edema associated with retinal vein occlusion (18 years of age and older) - Diabetic macular edema ((18 years of age and older) Participants undergo the following tests and procedures: - Medical history and physical examination - Eye examination to assess visual acuity (eye chart test) and eye pressure, and to examine pupils, lens, retina and eye movements. The pupils will be dilated with drops for this examination. - Fluorescein angiography to evaluate the eye's blood vessels. A yellow dye is injected into an arm vein and travels to the blood vessels in the eyes. Pictures of the retina are taken using a camera that flashes a blue light into the eye. The pictures show if any dye has leaked from the vessels into the retina, indicating possible blood vessel abnormality. - Indocyanine green angiography to identify feeder vessels that may be supplying abnormal blood vessels. This procedure is similar to fluorescein angiography, but uses a green dye and flashes an invisible light. - Optical coherence tomography to measure retinal thickness. This test shines a light into the eye and produces cross-sectional pictures of the retina. These measurements are repeated during the study to determine if retinal thickening is getting better or worse, or staying the same. - Stereoscopic color fundus photography to examine the back of the eye. The pupils are dilated with eye drops to allow examination and photography of the back of the eye. - Triamcinolone acetonide injection to treat the eye. A numbing eye drop, an antibiotic eye drop, and an injected antibiotic are put in the eye before triamcinolone acetonide is injected into the eye's vitreous (jelly-like substance inside the eye). After the injection, the patient lies on his or her back for 30 minutes. An antibiotic eye ointment is used for 2 days following treatment. - Blood tests to measure liver and kidney function. Patients return to the clinic for follow-up visits 1, 4, and 7 days, and 1 month after the first treatment. Patients whose condition does not improve after 3 months do not receive any more injections, but return for eye examinations at least once a year for 3 years. Patients whose condition improves with treatment return for follow-up visits 6 and 9 months after the first injection and then every 6 months for 2 more years. At each visit, a determination is made whether another injection is needed. After each repeat injection, patients return for follow-up visits at 1, 4, and 7 days after the injection.

NCT00101764 ↗ Intravitreal v. Sub-tenon Injections of Triamcinolone Acetonide for Macular Edema in Retinal Disorders Completed National Eye Institute (NEI) Phase 1 2005-01-05 The use of intravitreal injections of corticosteroid (triamcinolone acetonide) appears to be a promising treatment for a variety of ocular diseases associated with inflammation. To date, the only drug available, "Kenalog-40 Injection" produced by Bristol Myers Squibb, has not been formulated for intraocular use. The purpose of this study is to evaluate the long-term safety and potential efficacy of novel intravitreal injections of a preservative-free formulation of triamcinolone acetonide (TAC-PF) at two dosage levels (4 mg and 8 mg) compared to anterior sub-tenon injections of TAC-PF at 20 mg. The study will be a masked, randomized Phase I study that will enroll 120 participants with one of the following diseases: age-related macular degeneration (AMD), diabetic macular edema (DME), central retinal vein occlusion (CRVO), branch retinal vein occlusion (BRVO), or any other retinal disease with associated macular edema. At least 21 participants will be enrolled in the four designated disease strata: AMD, DME, CRVO, and BRVO. The remaining 36 participants may have one of these diseases or may be enrolled with another retinal disease. Within each disease strata, at least seven participants will be randomized to each dosing group. The participants will be randomly assigned to one of the three treatment groups. The primary outcome will be an assessment of post-injection intraocular toxicity-related events during the 3-year follow-up, including cataract formation, development of glaucoma, and any adverse event preventing retreatment. The secondary outcomes will be an improvement in best-corrected visual acuity (BCVA, EVA) and decreases in retinal thickening and area of leakage, from baseline to year 1.

Kenalog-80: Clinical Trials Update, Market Analysis, and Industry Projection

Last updated: October 30, 2025


Introduction

Kenalog-80, a corticosteroid formulation containing 80 mg of triamcinolone acetonide per vial, is primarily utilized for intra-articular, intralesional, and dermatologic indications. As a long-standing therapeutic agent, ongoing clinical research and market dynamics influence its positioning within the global pharmaceutical landscape. This analysis synthesizes recent clinical trials, evaluates market trends, and projects future growth trajectories.


Clinical Trials Update

Recent Investigations and Focus Areas

Recent clinical trials concerning Kenalog-80 largely concentrate on expanding its therapeutic applications, optimizing delivery methods, and assessing safety profiles. Notably:

  • Osteoarthritis and Rheumatoid Arthritis: Several Phase IV studies have evaluated intrarticular triamcinolone acetonide’s efficacy for osteoarthritis of the knee, with findings supporting sustained symptom relief over placebo, consistent with previous literature [1]. These studies emphasize injection frequency optimization to mitigate adverse effects.

  • Dermatological Uses: Trials investigating intralesional Kenalog-80 for keloids and hypertrophic scars report significant improvements with minimal adverse effects, reinforcing its role as a first-line intralesional corticosteroid [2].

  • Emerging Indications: Investigations into its role in managing inflammatory ocular conditions and certain autoimmune diseases are ongoing, although these are limited to early-phase trials with preliminary safety data available.

Safety and Pharmacovigilance

Post-marketing surveillance indicates that adverse events remain consistent with corticosteroids' known profiles, including skin atrophy, hypopigmentation, and systemic effects with improper dosing. Notably, recent trials have emphasized patient-specific dosing adjustments to minimize systemic side effects and improve outcomes [3].

Innovations in Formulation and Delivery

Research into novel delivery formulations, such as nanoparticle-based encapsulation, aims to enhance localized drug retention and reduce systemic exposure. Limited early-stage trials have shown promising pharmacokinetic improvements, though clinical efficacy data remain pending [4].
