Glaucoma
Conditions
Brief summary
The purpose of this study is to compare the safety and efficacy of XEN-45 to trabeculectomy in participants with open angle glaucoma refractory to topical medical therapy.
Detailed description
This is a multi-center, randomized, parallel group, prospective, open-label clinical trial to evaluate the ability of XEN-45 to reduce intraocular pressure (IOP) and reduce the amount of topical IOP-lowering medications in participants poorly controlled on topical therapy. The planned study duration is 12 months. Participants were to be screened for enrollment and eligible candidates were to be approached to ascertain interest in study participation. Eligible participants were to be randomized 2:1; resulting in approximately 95 eyes implanted with XEN-45 and 44 eyes received trabeculetomy by study end.

| Patient-reported Outcomes (PRO): Change From Baseline in Symptom and Health Problem Checklist (SHPC-18) Scores | Baseline (Preoperative) to Month 6 | The SHPC-18 is an 18-item questionnaire that asks participants being treated for glaucoma questions about eye symptoms or problems they may experience. There are two domains: Local Eye Symptoms (7 items) subscale score 0 to 700 divided by 7 and Visual Function Problem (11 items) subscale score 0 to 1100 divided by 11. The scores of each subscale ranges from from 0 (not at all) to 100 (a lot); higher scores indicate more bother. A frequency score was calculated by summing the individual response scores of each item, and ranges from 0 to 7 for Local Eye Symptom and from 0 to 11 for Visual Function. A total bothersome score for the SHPC-18 is calculated by summing all 18 items scores, resulting in a range from 0 to 1800, then dividing the sum by 18, to create a total bothersome score ranging from 0 (not at all) to 100 (a lot); higher scores indicate more bother. A negative change from Baseline for all scales and subscales indicates improvement. |

These sub-scores are transformed to impairment percentages (range from 0 to 100), with higher numbers indicating greater impairment and less productivity. A negative change from Baseline indicates improvement. |

One eye, the worse eye, from each participant was selected as the study eye. The worse eye was defined using the visual field mean deviation (MD) at baseline, with the worse eye having the most negative MD. In the case where the MD was the same in both eyes, to two decimal places, the worse eye is defined as the eye with the higher IOP.

Patient-reported Outcomes (PRO): Change From Baseline in Symptom and Health Problem Checklist (SHPC-18) Scores
The SHPC-18 is an 18-item questionnaire that asks participants being treated for glaucoma questions about eye symptoms or problems they may experience. There are two domains: Local Eye Symptoms (7 items) subscale score 0 to 700 divided by 7 and Visual Function Problem (11 items) subscale score 0 to 1100 divided by 11. The scores of each subscale ranges from from 0 (not at all) to 100 (a lot); higher scores indicate more bother. A frequency score was calculated by summing the individual response scores of each item, and ranges from 0 to 7 for Local Eye Symptom and from 0 to 11 for Visual Function. A total bothersome score for the SHPC-18 is calculated by summing all 18 items scores, resulting in a range from 0 to 1800, then dividing the sum by 18, to create a total bothersome score ranging from 0 (not at all) to 100 (a lot); higher scores indicate more bother. A negative change from Baseline for all scales and subscales indicates improvement.

Percentage of Participants With Postoperative Treatment-Emergent Adverse Events of Special Interest (AESIs)
AE=any untoward medical occurrence in a clinical investigation participant administered drug;it does not necessarily have to have a causal relationship with the treatment. TEAE is an AE either reported for the first time or worsening of a pre-existing event after first dose of study drug and within 30 days of the last administration of study drug. Postoperative AEs included but were not limited to: angle recession, anterior chamber changes, BCVA loss,bleb leak, blebitis, cataract, choroidal effusion, chronic pain, corneal edema, cyclodialysis, Dellen, device malfunction, endophthalmitis, fixed dilated pupil, hyphema, hypotony, implant issues, increase in corneal thickness/IOP, explant, iridodialysis, iritis, loss of eye, etc.Worse eye=eye if both eyes met inclusion criteria. Worse eye was defined using visual field MD at Baseline, with worse eye having the most negative MD. In cases where MD was the same in both eyes to two decimal places, worse eye was defined as eye with higher IOP.
Time frame: Median follow-up of 366.0 days

Only categories with at least one participant with event in the study eye are reported. The worse eye was selected as the study eye if both eyes met inclusion criteria. The worse eye was defined using visual field MD at Baseline, with the worse eye having the most negative MD. If MD was same in both eyes to two decimal places, the worse eye=eye with higher IOP.

PRO: Percent Change From Baseline in Work Productivity and Activity Impairment (WPAI): Percent Overall Work Impairment Due to Health
WPAI-General Health (GH) is 6-question participant rated questionnaire to determine the amount of absenteeism, presenteeism, work productivity loss and daily activity impairment attributable to general health. It yields 5 sub-scores: hours actually worked, work time missed due to health impairment while working, impairment while working due to health, overall work impairment due to health, activity impairment due to health. These sub-scores are transformed to impairment percentages (range from 0 to 100), with higher numbers indicating greater impairment and less productivity. A negative change from Baseline indicates improvement.
Time frame: Baseline (Preoperative) and Month 12
Population: ITT Population included all enrolled eyes/participants that were randomized to and received study glaucoma surgery (XEN-45 or trabeculectomy). Analyses were based on the randomized surgery. Overall Number of Participants Analyzed is the number of participants with data available for analysis at the given timepoint.
