A Phase 2 interventional study of Aflibercept Injection and Ahmed Tube Surgery in Glaucoma, sponsored by University of Miami. Not yet recruiting at 1 site in United States. Open to participants aged 18 Years to 85 Years. Per ClinicalTrials.gov, last updated 2026-10-23.
Sponsored by University of Miami · Phase 2, Interventional, and Treatment
The purpose of this study is to determine if injections of aflibercept into the eye given at the end of the Ahmed tube surgery as well as at postoperative months one and two would improve eye pressure control compared to standard surgery with no aflibercept.
1,844 studies on the registry are indexed under Glaucoma; 233 are open to participants now.
This study's planned enrollment of 100 is above the median of 65 across 1,296 interventional studies indexed under Glaucoma.

Exclusion Criteria:
Highly effective contraceptive measures include:
and/or sexual abstinence
Participants will undergo standard of care Ahmed tube surgery and will receive one 8 mg injection of intravitreal aflibercept at three timepoints in the study: at the conclusion of surgery, Postoperative Month 1, Postoperative Month 2. Total duration of participation in this arm is 6 months
Drug: Aflibercept Injection · Procedure: Ahmed Tube Surgery
Participants will undergo standard of care Ahmed tube surgery without any injections of intravitreal aflibercept. Total duration of participation in this arm is 6 months.
Procedure: Ahmed Tube Surgery
Aflibercept 8 mg will be administered intravitreally at three time points: immediately after Ahmed tube surgery, at postoperative month 1, and at postoperative month 2.
Also known as: Eylea
Participants will receive standard of care Ahmed tube surgery.
Intraocular pressure
Intraocular pressure (IOP) measured by Goldmann applanation tonometry and reported in millimeters of mercury (mmHg). IOP represents the pressure within the eye and is assessed at each scheduled postoperative follow-up visit.
Time frame: Postoperative day 1, week 1, month 1, month 2, and month 3
Surgical failure
Percentage of participants who meet any predefined surgical failure criterion, including: (1) intraocular pressure (IOP) \>21 mmHg and \<20% reduction from baseline on two consecutive visits after Month 3; (2) IOP \<5 mmHg on two consecutive visits after Month 3; (3) requirement for additional glaucoma surgery; or (4) loss of light perception vision.
Time frame: up to 6 months
Medication Burden
Medication burden assessed as the number of intraocular pressure (IOP) lowering medications used by participants daily.
Time frame: Postoperative day 1, week 1, month 1, month 2, month 3, and month 6
Hypertensive phase
Percentage of participants who experience a hypertensive phase, defined as intraocular pressure (IOP) greater than 21 mmHg, with or without glaucoma medications, during the first 3 months after surgery following a reduction of IOP to less than 22 mmHg during the first postoperative week. Hypertensive phase is a known risk factor for surgical failure.
Time frame: Up to 3 months
Treatment adverse events and serious treatment adverse events
Percentage of participants experiencing at least one treatment-related adverse event (AE) or serious adverse event (SAE).
Time frame: Up to 6 months
Plan to share: No

Start is estimated for Dec 2026; primary completion for Jun 2028, 18 months later.
Of 51 phase 2 interventional studies under Glaucoma, half reached primary completion within 11 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 21. This study's planned 18 months is above that.
