A Real-world Study of DEXYCU in the Treatment of Inflammation After Cataract Surgery

Phase 4
Completed
Conditions
Inflammation
Cataract
Interventions
Drug: Dexycu
Registration Number
NCT06497699
Lead Sponsor
Ocumension Therapeutics (Shanghai) Co., Ltd
Brief Summary

This is a prospective, real-world study aimed to evaluate the efficacy and safety of Dexycu in treating postoperative inflammation of cataracts.

Detailed Description

To evaluate the efficacy and safety of Dexycu in treating postoperative inflammation of cataracts in real-world clinical settings, medical history and follow-up data from 113 subjects of Dexycu group and 150 subjects of external control group will be prospectively collected in Hainan, China. Additionally, questionnaires will be collected from surgeons on 30 cases to evaluate the difficulty, duration and safety of the Dexycu injector.

Primary Outcome Measures
NameTimeMethod
Anterior chamber cell clearing rateDAY 8

The primary outcome is to compare the ratio of subjects with anterior chamber cell grade 0 at day 8 after cataract surgery of both Dexycu group and external control group.

The slit lamp examination for anterior chamber cells (ACC) is a recognized way to measure inflammation in the anterior chamber. During the slit lamp examination, the number of anterior chamber cells are quantified and graded: grade 0 (absent, 0 cells), grade 1 (1 to 5 cells), grade 2 (6 to 15 cells), grade 3 (16 to 30+ cells), or grade 4 (hypopyon). Anterior chamber cell clearing occurs when all the ACC are absent (grade 0).

Secondary Outcome Measures
NameTimeMethod
Anterior chamber flare clearing ratesDAY 1 & 8

Compare the percentage of subjects with anterior chamber flare grade 0 at Day 1 and 8 after cataract surgery of both Dexycu group and external control group.

The slit lamp examination for anterior chamber flare (ACF) is a recognized way to measure inflammation in the anterior chamber. During the slit lamp examination, the number of anterior chamber cells are quantified and graded: grade 0 (absent), grade 1 (trace), grade 2 (mild intensity), grade 3 (moderate intensity), or grade 4 (strong intensity). Anterior chamber flare clearing occurs when all the ACC are absent (grade 0).

Change in central macular thicknessDAY 1 & 8

Compare the change in central macula thickness at Day 1 and 8 of the Dexycu group and external control group.

Anterior chamber cell clearing ratesDAY 1 & 30

Compare the percentage of subjects with anterior chamber clearing grade 0 at Day 1 and 30 after cataract surgery of both Dexycu group and external control group.

The slit lamp examination for anterior chamber cells (ACC) is a recognized way to measure inflammation in the anterior chamber. During the slit lamp examination, the number of anterior chamber cells are quantified and graded: grade 0 (absent, 0 cells), grade 1 (1 to 5 cells), grade 2 (6 to 15 cells), grade 3 (16 to 30+ cells), or grade 4 (hypopyon). Anterior chamber cell clearing occurs when all the ACC are absent (grade 0).

Mean anterior chamber cell scoreDAY 1 & 8 & 30

Compare the mean score of anterior chamber cell at Day 1 , 8 and 30 of the Dexycu group and external control group.

Mean anterior chamber flare scoreDAY 1 & 8 & 30

Compare the mean score of anterior chamber flare at Day 1, 8 and 30 of the Dexycu group and external control group.

Evaluate the ease of use of the Dexycu ejectorDAY 0

After the cataract surgery, surgeons are asked to fill in a questionaire designed to collect subjective assessment on the experience of using the drug ejector. 30 questionaires in total were collected.

Change in visionDAY 1 & 8 & 30

Use standard logarithmic visual acuity chart to measure and compare the change in vision of the Dexycu group and external control group, before and after cataract surgery.
