Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE3
• Total Enrollment: 285 participants

Brief Summary

This is a phase III, prospective, randomised, double-masked, placebo-controlled, parallel-design, multicenter study of the efficacy, safety and pharmacokinetics of 9% dexamethasone intraocular injection for the treatment of inflammation associated with cataract surgery.

Detailed Description

This is a prospective, randomized, double-blindmasked, placebo-controlled, parallel- design, multicenter study of subjects over 40 years undergoing cataract surgery. Subjects meet the inclusion criteria and do not meet any exclusion criteria are randomiszed to the dexamethasone implant group or placebo group at a ratio of 2:1.

Subjects received a single does injection in the study eye immediately after the completion of cataract surgery. The investigational drug comes with a special injection device and injection guide.

All subjects will be administered to the study eye with quinolone topical antibiotic eye drops or their equivalent 3 days before and 7 days after surgery.

3. The patient must demonstrate best corrected visual acuity (BCVA) of 20/30-20/200 in the study eye and better than 20/200 in the fellow eye.

4. The patient must be considered by the Investigator to have visual acuity potential. greater than 20/30 in the study eye.

5. The patient must have a corneal endothelial cell count by specular microscopy in the study eye of at least 2000 cells/mm2 with normal cell morphology.

6. A female patient of childbearing potential must have a negative pregnancy test on Day 0 and be using an effective method of birth control from Screening for the duration of the study.

2. Patients who have received a periocular corticosteroid injection in the study eye in the 3 months prior to screening.

3. Patients who have received any intravitreal corticosteroid delivery vehicle (e.g.,Retisert, Ozurdex, Iluvien) in the study eye at any time.

4. Patients who anticipate requiring treatment with any corticosteroids( by any route,except inhalation), during the study.

5. Patients with an allergy or hypersensitivity to dexamethasone.

9. Patients who have undergone prior intraocular laser surgery in the study eye within 3 months prior to screening.

10. Patients with planned intraocular or laser surgery in the study eye for the duration of the study.

11. Patients with any signs of intraocular inflammation in either eye at screening.

12. Patients with evidence of corneal abnormality or dystrophy (e.g. opacities, guttae,clouding, etc.) or an inability to obtain an acceptable specular micrograph at Screening.

13. Patients with a history of chronic uveitis from any cause in either eye.

14. Patients who have received any prior intravitreal injections in the study eye.
