Overview of the trials
Clinical trials with Triamcinolone Acetonide are testing it in different patient groups and for different medical problems, especially pain, joint disorders, ear conditions, and some skin and eye diseases.[1]
Most of the studies in the source data are Phase 3 trials, which usually compare treatments in larger groups of patients.[1] One study is Phase 2, and one is a low-intervention study in children with esophageal stricture after repair of esophageal atresia.[3]
Several trials are authorised, one is completed, and one is withdrawn.[1]
Conditions being studied
The trials cover a wide range of conditions. These include trapezius myofascial syndrome in fibromyalgia, frozen shoulder, rheumatoid arthritis, sudden sensorineural hearing loss, chronic shoulder pain, post-surgical scar pain, carpal tunnel syndrome, hidradenitis suppurativa, and osteoarthritis of the first carpometacarpal joint.[1]
Other studies include idiopathic inflammatory myopathies, geographic atrophy, strictures after esophageal atresia repair, and X-linked retinitis pigmentosa caused by RPGR mutations.[1][2]
This means the research is not limited to one disease area. Instead, Triamcinolone Acetonide is being studied as part of different treatment strategies in several specialties, including rheumatology, ear, orthopedics, dermatology, and ophthalmology.[1]
Study designs and phases
Most of the studies are interventional, meaning researchers assign a treatment and then compare outcomes.[1]
The trials are mostly in Phase 3, including studies in fibromyalgia-related trapezius pain, rheumatoid arthritis, frozen shoulder, carpal tunnel syndrome, hidradenitis suppurativa, chronic shoulder pain, post-surgical scar pain, and osteoarthritis of the thumb base joint.[1]
The Phase 2 studies include sudden sensorineural hearing loss and geographic atrophy, and the withdrawn Phase 3 study focused on X-linked retinitis pigmentosa.[1]
Some trials compare Triamcinolone Acetonide with saline, placebo, physiotherapy, or other active treatments, while others use it as one option in a broader treatment plan.[1]
Who can participate
Eligibility depends on the condition being studied. Some trials include adults only, such as studies in rheumatoid arthritis, chronic shoulder pain, carpal tunnel syndrome, hidradenitis suppurativa, and idiopathic inflammatory myopathies.[1]
Other trials include children and teenagers, such as the study in atopic dermatitis and the study in strictures after esophageal atresia repair.[1]
Some studies require a very specific diagnosis, such as persistent sudden sensorineural hearing loss after unsuccessful conservative therapy, or unilateral Menière’s disease in a one-year follow-up study of vertigo control.[1]
In general, the trial data show that participation is limited to people who match the exact diagnosis, age group, and study setting chosen by the researchers.[1]
What the trials measure
The main study results are different from one trial to another. Pain studies often use a Numeric Rating Scale or Visual Analogue Scale, which are simple tools for rating pain severity.[1]
Shoulder studies use the Shoulder Pain and Disability Index, which measures both pain and how much the problem limits daily activities.[1]
The rheumatoid arthritis studies measure remission or disease activity, including remission defined by DAS28-CRP and changes in disease activity over time.[1]
The hearing-loss study measures change in hearing threshold on day 30, while the Menière’s disease study measures control of vertigo attacks.[1]
Some studies also measure safety outcomes, such as adverse events, laboratory tests, electrocardiogram findings, eye examinations, and changes in eye pressure.[1][2]
Key trials using Triamcinolone Acetonide
The fibromyalgia trial studies local treatment of trapezius muscle pain and compares bupivacaine/triamcinolone with physiological saline and placebo. The main outcome is pain on the Visual Analogue Scale at weeks 2, 4, and 12.[1]
The sudden hearing loss trial uses intracochlear Triamcinolone Acetonide in patients with persistent sudden sensorineural hearing loss after unsuccessful conservative therapy. The main outcome is the mean change in hearing threshold at day 30 in the frequencies most affected by the hearing loss.[1]
The rheumatoid arthritis bridging trial compares corticosteroid bridging with Kenacort-A 40 against a JAK inhibitor strategy. The main outcome is the percentage of patients in remission at three months, using DAS28-CRP.[1]
The frozen shoulder study compares physical therapy, corticosteroid injections, and their combination to see which approach improves pain and function at 3 months. The main outcome is the Shoulder Pain and Disability Index.[1]
The carpal tunnel syndrome study tests an initial ultrasound-guided injection strategy against surgery as the main treatment. Success is defined by a Boston Carpal Tunnel Questionnaire symptom score of 1.5 or less after one year.[1]
The hidradenitis suppurativa trials use intralesional Triamcinolone Acetonide as part of comparison arms. Their main outcome is HiSCR50 at Week 16, which means at least a 50% drop in abscess and inflammatory nodule count without worsening of draining tunnels or fistulas.[1]
The thumb base osteoarthritis study checks whether intra-articular corticosteroid injections are better than saline after 4 weeks and compares three strategies at 12 weeks. It measures pain during activities using a Numeric Rating Scale.[1]
The esophageal atresia trial in children studies intralesional steroid injections to see whether they can prevent hard-to-treat strictures and reduce the number of dilatations needed over six months.[3]
The idiopathic inflammatory myopathy studies include Triamcinolone Acetonide among many background treatments, and one study focuses on long-term safety outcomes such as adverse events, laboratory results, lung function measures, and suicide-risk screening.[2]
What these studies mean for patients
For patients, these trials show that Triamcinolone Acetonide is being explored in many different ways, not just for one disease.[1]
Some studies ask whether it can reduce pain, improve movement, restore hearing, or help control inflammation better than another treatment.[1]
Other studies are mainly safety studies, especially when the medicine is used in a special way, such as inside the ear, under the skin, or near a nerve.[1]
Because the trials use different diseases, ages, and treatment plans, the results will not apply to every patient in the same way.[1]
