简要总结
The VividWhite Glaucoma Implant (VW-51) is a novel surgical implant designed to treat glaucoma. This study is a 12-month, 65-participant non-comparative multicentre study to assess the safety and effectiveness of the VW-51 implant.
详细描述
A prospective multicentre non-comparative pivotal clinical study where all participants undergo treatment with a novel surgical implant (VW-51) and receive 12 months of clinical follow-up. The study aim is to assess the effectiveness, safety and participant experience of the VW-51 implant for the treatment of glaucoma. The study population will involve 65 adult participants with medically or surgically refractory glaucoma. The VW-51 implant is a leaf-shaped microfluidic device manufactured from flexible silicone, designed to be surgically implanted in the subconjunctival space, drain aqueous humor from the eye and reduce intraocular pressure to treat glaucoma.

入选标准
- •Glaucoma in the study eye, meeting the following requirements:
- •Glaucoma is diagnosed by the investigator based upon untreated intraocular pressure, disc appearance and visual field abnormalities, and where the disease type is one of: Primary open angle glaucoma (POAG); Chronic angle closure glaucoma (CACG) where the eye is pseudophakic and a laser iridotomy has previously been performed; Pigmentary open angle glaucoma; Exfoliation open angle glaucoma; Rubeotic glaucoma that is treated and regressed/quiescent; Steroid-induced glaucoma; or Juvenile open angle glaucoma (JOAG).
- •There has been failure of previous treatment for glaucoma (it is 'refractory'), meeting ONE of the following requirements:
- •i. Failure of medical treatment: inadequate IOP control on maximum tolerated medical therapy.
- •ii. Failure of previous glaucoma surgery (not more than one operation) with trabeculectomy, Xen/PreserFlo, non-penetrating glaucoma surgery, a previously removed suprachoroidal drainage device, trabecular bypass (using iStents or Hydrus), or cilioablation.
- •c. The mean diurnal IOP at Screening/Baseline is ≥ 20 mmHg, and ≤ 40 mmHg.
- •d. The conjunctiva in the target quadrant is healthy, mobile and suitable for glaucoma surgery.
排除标准
- •in the study eye:
- •Advanced glaucomatous optic neuropathy that threatens fixation, in the opinion of the investigator.
- •The glaucoma type is any of the following: Acute Angle Closure Glaucoma (AACG); Chronic Angle Closure Glaucoma where the eye is phakic; Congenital glaucoma; or Secondary glaucoma of any type not specified in the inclusion criteria, including inflammatory glaucoma, active neovascular/rubeotic glaucoma, traumatic glaucoma, Iridocorneal Endothelial (ICE) Syndrome, and silicone oil induced glaucoma.
- •Previous glaucoma surgery with: a tube-and-plate glaucoma drainage device (GDD, e.g. Molteno, Baerveldt, Ahmed, Schocket); an in-situ suprachoroidal implant; or multiple previous operations for glaucoma.
- •Cataract surgery or any other ocular surgery is indicated at the time of study intervention or is anticipated to be required during the study duration.
- •Central corneal endothelial cell density less than specified age-related thresholds at screening.
- •Intraocular silicone oil.
- •Significant corneal, retinal, inflammatory or infective ophthalmic pathology (full details specified in the protocol).

主要结局
Complete success by efficacy and safety criteria
时间窗: Study completion (12 months)
Efficacy Criteria: 1. Intraocular pressure (IOP) is less than or equal to 21 mmHg. 2. IOP is reduced by greater than or equal to 20% compared to baseline (mean diurnal). 3. Treatment with the same number or fewer classes of topical glaucoma medication than at baseline. 4. No requirement for: further glaucoma surgery indicated for efficacy (at any time during the study); or systemic/oral ocular hypotensive medication to achieve target IOP in the study eye (at any time during the study). Safety Criteria: 5. IOP is greater than or equal to 6 mmHg. 6. No adverse events of special significance in the study eye (as specified by the protocol; for example further glaucoma surgery indicated for safety).
