Trial summary
Proliferative vitreoretinopathy (PVR) is the most common cause for failure of rhegmatogenous retinal detachment repair and is characterized by the growth and contraction of cellular membranes within the vitreous cavity on both sides of the retinal surface as well as intraretinal fibrosis.

About this study
Official title: Treatment of Proliferative Vitreoretinopathy With Intravitreal Infliximab
Proliferative vitreoretinopathy (PVR) is the most common cause for failure of rhegmatogenous retinal detachment repair and is characterized by the growth and contraction of cellular membranes within the vitreous cavity on both sides of the retinal surface as well as intraretinal fibrosis.
Multiple therapeutic agents have been tried as an adjunctive to retinal detachment surgery for PVR with no consistent efficacy. Tumor necrosis factor-α (TNF-α), which is a prominent inflammatory cytokine, is secreted in response to trauma, infection, and inflammation. It is a key mediator of ocular inflammation and its interactions with the retinal pigment epithelium (RPE) cell contribute to the initiation of PVR. This may occur through the action of TNF-α on the RPE cells inducing changes in cellular morphologies that lead to the formation of fibroblastic cells.

Infliximab (Remicade; Janssen Biotech, Horsham, PA, USA) is a mouse-human chimeric antibody that neutralizes the biological activity of TNF-α by high-affinity binding to the soluble and transmembrane forms of TNF-α, therefore preventing the effective binding of TNF-α with its receptors. Infliximab is used in the treatment of various ocular and systemic inflammatory conditions. Furthermore, intravitreal infliximab has been used for the treatment of various ocular diseases and has proven to be generally safe for the short term in inflammatory ocular conditions. A recent study showed that intravitreal infliximab can inhibit the development of PVR and reduce levels of cytokines in an experimental dispase-induced PVR model.
The purpose of this randomized controlled trial is to evaluate the efficacy of intravitreal infliximab injection as an adjunct to pars plana vitrectomy in the treatment of PVR associated with primary rhegmatogenous retinal detachment.
Read the detailed description
Proliferative vitreoretinopathy (PVR) is the most common cause for failure of rhegmatogenous retinal detachment repair and is characterized by the growth and contraction of cellular membranes within the vitreous cavity on both sides of the retinal surface as well as intraretinal fibrosis.
The incidence of PVR in all cases of retinal detachment is estimated to be 5- 10%. The incidence of PVR has largely remained unchanged in prospective studies despite the evolution of vitreoretinal techniques over the past 25 years, including valved trocars and smaller gauge instrumentation.
Numerous risk factors for the development of PVR have been identified. Almost all risk factors for PVR are associated with intravitreal dispersion of retinal pigment epithelial cells or breakdown of the blood-ocular barrier. Following a retinal break, the retinal pigment epithelial (RPE) cells are exposed to the vitreous cavity to react to growth factors and cytokines in the vitreous, resulting in a forward feedback to secret more growth factors and cytokines to further stimulate cellular responses.
Multiple therapeutic agents have been tried as an adjunctive to retinal detachment surgery for PVR with no consistent efficacy. Tumor necrosis factor-α (TNF-α), which is a prominent inflammatory cytokine, is secreted in response to trauma, infection, and inflammation. It is a key mediator of ocular inflammation and its interactions with RPE cells contribute to the initiation of PVR. This is because TNF-α was found to act on the RPE cells consequently inducing changes in cellular morphologies leading to the formation of fibroblastic cells. Additionally, if TNF-α is combined with other growth factors, a strong synergistic effect can be induced to form epithelial-mesenchymal transition (EMT)-associated fibrotic focus.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Anatomical success (time frame: 9 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04891991, which also lists 14 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Jan 2024.
