Inclusion criteria

  • Age 18 to 85 years, inclusive.
  • Open-angle glaucoma (primary or secondary such as pseudoexfoliative, pigmentary, steroid response) that is inadequately controlled on tolerated medical therapy with intraocular pressure greater than or equal to 18 mm Hg and less than or equal to 40 mm Hg.

Exclusion criteria

Exclusion Criteria:

  • Unwilling or unable to give consent, unwilling to accept randomization, or unable to return for scheduled protocol visits.
  • No light perception vision.
  • Prior aqueous shunt or cyclodestructive procedure.
  • Prior exposure to anti-VEGF in either eye.
  • Diabetic retinopathy.
  • Wet age-related macular degeneration.
  • Retinal vein occlusion.
  • Choroidal neovascular membrane.
  • History of cystoid macular edema.
  • Vitreous prolapse.
  • Previous or active ocular neovascularization.
  • Iridocorneal endothelial syndrome.
  • Epithelial or fibrous downgrowth.
  • Chronic or recurrent uveitis, or acute uveitis within 90 days of surgery.
  • Use of topical steroids within 30 days of surgery.
  • Conjunctival scarring sufficient to preclude Ahmed implantation in preferred quadrant.
  • Scleral buckle.
  • Severe posterior blepharitis.
  • Aphakia.
  • Unwilling to discontinue contact lens use after surgery.
  • Need for glaucoma surgery combined with other ocular procedures (i.e. cataract surgery, penetrating keratoplasty, or retinal surgery) or anticipated need for additional ocular surgery.
  • Best corrected visual acuity 20/200 or worse in fellow eye.
  • Uncontrolled blood pressure (systolic blood pressure >165 mmHg or diastolic blood pressure >95 mmHg) or the investigator is concerned would have unstable blood pressure during the course of the study, such as due to compliance issues.
  • History of cerebrovascular accident or myocardial infarction within 180 days of surgery.
  • Hemodialysis and/or history of renal transplant
  • Known history of sensitivity to any compounds of the study formulation
  • History of other disease, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use of aflibercept 8 mg or that might affect interpretation of the results of the study or render the patient at high risk for treatment complications
  • Participation in an investigational study within 30 days prior to screening visit that involved treatment with any drug (excluding vitamins and minerals) or device
  • Pregnant or nursing women.
  • Men or women of childbearing potential (WOCBP)* who are unwilling to practice highly effective contraception prior to the initial dose/start of the first treatment, during the study, and for at least 3 months after the last dose.

Highly effective contraceptive measures include:

  1. stable use of combined (estrogen and progestogen-containing) hormonal contraception (oral, intravaginal, transdermal) or progestogen-only hormonal contraception (oral, injectable, implantable) associated with inhibition of ovulation initiated 2 or more menstrual cycles prior to screening
  2. intrauterine device (IUD); intrauterine hormone-releasing system (IUS)
  3. bilateral tubal ligation
  4. vasectomy
  5. condom plus contraceptive sponge, foam, or jelly, or diaphragm plus contraceptive sponge, foam, or jelly
  6. and/or sexual abstinence

    • Postmenopausal women must be amenorrhoeic for at least 12 months without an alternative medical cause in order not to be considered of childbearing potential. Pregnancy testing and contraception are not required for women with documented hysterectomy or tubal ligation.
    • Vasectomized partner or vasectomized study participant must have received medical assessment of the surgical success.
    • Sexual abstinence is considered a highly effective method only if defined as refraining from heterosexual intercourse during the entire period of risk associated with the study treatments. The reliability of sexual abstinence needs to be evaluated in relation to the duration of the clinical trial and the preferred and usual lifestyle of the subject.
    • Periodic abstinence (calendar, symptothermal, post-ovulation methods), withdrawal (coitus interruptus), spermicides only, and lactational amenorrhea method (LAM) are not acceptable methods of contraception. Female condom and male condom should not be used together.

Study arms

  • Experimental
    Ahmed Tube Surgery with Aflibercept Intravitreal Injection Group

    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

  • Active comparator

    Procedure: Ahmed Tube Surgery

Interventions

  • 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

  • ProcedureAhmed Tube Surgery

What researchers measure

Primary outcomes

  1. 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

Secondary outcomes

  1. 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

  2. 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

  3. 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

  4. 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

ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

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.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
