Trial Summary

What is the purpose of this trial?

This is a multicenter, 2-arm, randomized, prospective study of patients slated for bilateral cataract extraction. One eye will be randomized to the Study Arm, and the fellow eye will be randomized to the Control Arm.

Will I have to stop taking my current medications?

The trial does not specify if you need to stop taking your current medications, but it excludes those taking oral anti-inflammatory medications for systemic diseases, except for low-dose aspirin and ibuprofen for headaches.

Is triamcinolone acetonide generally safe for humans?

Triamcinolone acetonide has been used in many patients for conditions like asthma and nasal issues, with most experiencing no serious side effects. However, some people have reported side effects like weight gain, menstrual changes, high blood pressure, and swelling.12345

Eligibility Criteria

This trial is for patients scheduled for cataract surgery in both eyes. It's not clear what the specific inclusion or exclusion criteria are, but typically participants would need to be adults with a diagnosis of cataracts and no other major eye diseases.

Inclusion Criteria

I am willing and able to follow the study's requirements and visit schedule.
I am at high risk for surgery complications but have had no active disease or treatment in the last year.
Participants who do not meet the exclusion criteria may be enrolled.

Treatment Details

Interventions

  • Triamcinolone Acetonide
Trial Overview The study compares complication rates between two treatments during cataract surgery. One eye gets NSAID, OMIDRIA, and triamcinolone (Study Arm), while the other eye receives standard care (Control Arm). The assignment of each treatment to an eye is random.
Participant Groups
2Treatment groups
Experimental Treatment
Active Control
Group I: Study Arm (OMIDRIA)Experimental Treatment1 Intervention
* Pre-op, 1 drop ketorolac (0.5%) {Toradol}, 1 drop moxifloxacin (0.5%) {Avelox} * Prior to surgery: 1 drop ketorolac (0.5%), 1 drop moxifloxacin (0.5%) * Concl. of surgery while still in the OR: 1 drop ketorolac (0.5%), 1 drop moxifloxacin (0.5%), 1 drop prednisolone acetate (1%) {Pred Forte} * Post-op recovery: 1 drop ketorolac (0.5%), 1 drop moxifloxacin (0.5%), 1 drop prednisolone acetate (1%). Intraoperative interventions: intracameral phenylephrine {Sudafed} 1.0%/ketorolac 0.3%, {OMIDRIA} intracameral moxifloxacin (0.5%), and subconjunctival triamcinolone acetonide (0.4 mL, 10 mg/mL) {Kenalog}. In-office drops administered by study staff at the end of the 1-day visit: 1 drop ketorolac (0.5%), 1 drop moxifloxacin (0.5%), 1 drop prednisolone acetate (1%). Rescue therapy will be allowed, if necessary, at the discretion of the evaluating physician and will consist of prednisolone acetate (1%) QID (taper also at the discretion of the evaluating physician).
Group II: Control Arm (Standard of Care)Active Control1 Intervention
Self-administration of: Ketorolac (0.5%) {Toradol} four times daily (QID) x 1 day and moxifloxacin (0.5%) {Avelox} drops three times daily (TID) x 1 day before SX. On the Day of SX, eyes will receive in-office drops administered by study staff according to the following: * In pre-operative holding: 1 drop ketorolac (0.5%), 1 drop moxifloxacin (0.5%) * Immediately prior to SX: 1 drop ketorolac (0.5%), 1 drop moxifloxacin (0.5%) * At the conclusion of SX while still in the operating room: 1 drop ketorolac (0.5%), 1 drop moxifloxacin (0.5%), 1 drop prednisolone acetate (1%) Pred Forte} * Any time in post-op recovery: 1 drop ketorolac (0.5%), 1 drop moxifloxacin (0.5%), 1 drop prednisolone acetate (1%). Eyes will then self-administer the following postoperative interventions: ketorolac drops QID x 1 month. Prednisolone acetate tapering QID x1 week, TID x 1 week, twice daily (BID) x 1 week, and once daily (QD) x 1 week; and moxifloxacin drops TID x 1 week.

Findings from Research

In a study of 145 patients with severe bronchial asthma, repeated intramuscular injections of triamcinolone acetonide (Kenalog) resulted in excellent or good outcomes in 88.3% of cases, indicating its high efficacy for patients who did not respond to other treatments.
While Kenalog was effective, 13.8% of patients experienced side effects such as weight gain and increased blood pressure, highlighting the need for careful monitoring during prolonged steroid use.
The use of triamcinolone acetonide in the treatment of severe intrinsic bronchial asthma.Romański, B., Pawlik, K., Wilewska-Klubo, T.[2013]
Triamcinolone acetonide (Kenalog) injections into the nasal turbinates have been successfully used in over 60,000 patients for treating allergic and vasomotor rhinitis, showing positive results without serious side effects.
The authors highlight the importance of preventing complications, such as intravascular injections that can affect the retinal circulation, by proposing specific methods to avoid this risk.
Corticosteroid injections of the nasal turbinates: past experience and precautions.McCleve, D., Goldstein, J., Silver, S.[2019]
A new method using a 5.0-microm porous membrane filter can effectively isolate triamcinolone acetonide particles from its commercial suspension, significantly reducing the preparation time for intravitreal use.
This method successfully eliminates 99.7% of benzyl alcohol and 88.1% of high-viscosity carboxymethylcellulose, which may enhance the therapeutic efficacy of triamcinolone by minimizing additives that could interfere with its action.
