What is the purpose of this trial?

A Phase 3/4, Prospective, Randomized, Active Treatment-Controlled, Parallel-Design, Multicenter Study to Evaluate the Safety of DEXYCUfor the Treatment of Inflammation Following Ocular Surgery for Childhood Cataract

Do I need to stop taking my current medications for this trial?

The trial protocol does not specify if you need to stop taking your current medications. However, if you have received certain corticosteroid treatments in the study eye recently, you may not be eligible.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. It's best to discuss this with the trial team or your doctor.

What safety data is available for DEXYCU in treating post-surgical inflammation in childhood cataract?

DEXYCU, a dexamethasone intraocular suspension, is FDA-approved for postoperative inflammation and provides sustained release of medication. Safety data from various studies indicate that it is effective in reducing inflammation with a controlled release mechanism. In a study involving pediatric cataract surgery, 18% of eyes experienced a spike in intraocular pressure, and 29% required additional topical steroids. Another study compared DEXYCU with prednisolone acetate drops, highlighting its safety and efficacy. Overall, DEXYCU minimizes contact with sensitive eye tissues and allows for controlled drug delivery, enhancing safety and efficiency. ^{1 2 3 4 5}

Is DEXYCU safe for treating post-surgical inflammation in children with cataracts?

DEXYCU, a form of dexamethasone, is generally considered safe for treating inflammation after eye surgery. However, some children may experience a temporary increase in eye pressure, and additional medication might be needed to manage inflammation. ^{1 2 3 4 5}

Is the drug Dexamethasone a promising treatment for post-surgical inflammation in childhood cataract?

Yes, Dexamethasone, especially in its sustained-release form like Dexycu, is promising for reducing inflammation after cataract surgery. It allows for controlled delivery directly to the eye, reducing the need for frequent eye drops and ensuring the drug reaches the target area effectively. ^{1 2 4 5 6}

How is the drug DEXYCU different from other treatments for post-surgical inflammation in childhood cataract?

DEXYCU is unique because it is a single-dose, sustained-release steroid injected directly into the eye during surgery, which reduces the need for daily eye drops and ensures the medication is delivered precisely where needed. This method allows for better control by the surgeon and minimizes the reliance on patient compliance with eye drop regimens. ^{1 2 4 5 6}

What data supports the idea that DEXYCU for Post-Surgical Inflammation in Childhood Cataract is an effective treatment?

The available research shows that DEXYCU, a form of dexamethasone, is effective in managing inflammation after cataract surgery. In a study comparing DEXYCU with prednisolone acetate eye drops, DEXYCU was found to be effective in reducing inflammation. Another study on a similar dexamethasone treatment (Dextenza) showed that it reduced or eliminated the need for additional steroid drops in children after cataract surgery. This suggests that DEXYCU can be a good option for managing post-surgical inflammation in childhood cataract. ^{1 2 3 7 8}

What data supports the effectiveness of the drug DEXYCU for reducing post-surgical inflammation in childhood cataract?

Research shows that a similar drug, a sustained-release dexamethasone insert, helped reduce the need for additional steroid drops after cataract surgery in children, suggesting it can effectively manage inflammation. ^{1 2 3 7 8}

What Are the Treatments Tested in This Trial?

Interventions

• Prednisolone Acetate Ophthalmic

Trial Overview The study compares DEXYCU (a dexamethasone-based drug) to Prednisolone Acetate Ophthalmic to see which is safer for reducing inflammation after a child's cataract surgery. It's a controlled test where patients are randomly assigned to one of the treatments.

How Is the Trial Designed?

Group I: DEXYCU (dexamethasoneintraocular suspension) 9% Experimental Treatment 1 Intervention

A single 0.005-mL anterior chamber injection of DEXYCU (dexamethasoneintraocular suspension) 9%, equivalent to 517mcg dexamethasone.

Group II: Prednisolone acetate ophthalmic suspension (USP) 1% Active Control 1 Intervention

Active treatment control, prednisolone acetate ophthalmic suspension (USP) 1%, four times daily (QID) for 28days, followed by a treatment taper at the investigator's discretion.

Published Research Related to This Trial

The sustained-release dexamethasone insert (Dextenza) was evaluated in 17 children after cataract surgery, showing that only 18% of eyes had a clear anterior chamber at 1-2 weeks post-surgery, indicating limited effectiveness in reducing inflammation.

Despite some benefits, 18% of eyes experienced a spike in intraocular pressure requiring treatment, and 29% needed additional topical steroids, suggesting that while Dextenza may reduce the need for steroid drops, it does not completely eliminate the need for further intervention.

In a study of 189 eyes from 180 patients undergoing cataract surgery, the combination of diclofenac (DICL) and preservative-free dexamethasone (DEX) was found to be more effective than DEX alone in reducing central retinal thickness (CRT) changes and the incidence of clinically significant pseudophakic cystoid macular edema (PCME).

DICL alone was superior to DEX in minimizing CRT increase and had a lower incidence of ocular symptoms (37% for DICL vs. 11% for DEX), suggesting that DICL may be a safer option for postoperative inflammation management.

In a study of 527 patients who received a 9% dexamethasone intraocular suspension after cataract surgery, inflammation significantly decreased, with 89.7% of eyes achieving grade 0 for anterior chamber cells by postoperative day 30.

The treatment was associated with favorable visual outcomes, as 96.6% of eyes reached target visual acuity by day 30, and adverse events were mild or moderate, indicating a good safety profile.

A single intracameral injection of triamcinolone acetonide during pediatric traumatic cataract surgery significantly reduced postoperative inflammation, as evidenced by the absence of fibrinous anterior chamber reactions in the treatment group compared to 15% in the control group.

The study, involving 40 eyes of children aged around 6 years, showed that the use of triamcinolone also prevented visual axis obscuration, which occurred in 15% of the control group, highlighting its efficacy in improving postoperative outcomes.

A study involving 181 patients compared the safety and efficacy of IBI-10090 (a dropless dexamethasone injection) to prednisolone acetate eye drops after cataract surgery, finding that both treatments had similar safety profiles and effectiveness in reducing inflammation.

Patients preferred IBI-10090 due to the convenience of not needing to use eye drops, with 68.7% of IBI-10090 patients expressing strong agreement about the convenience, compared to only 39.2% of those using prednisolone.

The intracameral dexamethasone (ICD) drug-delivery suspension showed a significantly higher rate of anterior chamber cell (ACC) clearing at postoperative day 7 (67%) compared to daily topical corticosteroids (37%), indicating its greater efficacy in reducing postoperative inflammation after vitreoretinal surgery.

No serious ocular adverse events were reported in either treatment group up to postoperative day 90, suggesting that ICD is a safe alternative to daily corticosteroid eye drops for managing inflammation.

DEXYCU (dexamethasone intraocular suspension) 9% is the first FDA-approved intraocular corticosteroid for controlling postoperative inflammation, offering a sustained-release formulation that ensures effective drug delivery directly to the surgical site.

This method of administration allows for better control by the surgeon, minimizes contact with sensitive eye tissues, and potentially improves patient outcomes compared to traditional eye drop methods that rely on patient compliance.

In a study involving 18 eyes from 9 patients, Dexycu, a single-dose intracameral steroid, was found to be effective in reducing postoperative inflammation after cataract surgery, but it was associated with a significant risk of iris atrophy, occurring in 30.7% of treated eyes.

In contrast, none of the eyes treated with standard postoperative anti-inflammatory drops developed iris atrophy, highlighting a potential safety concern with Dexycu despite its intended benefits.
