Filter by:This study is intended to assess safety, tolerability and biological activity of a repeat IVT injection of UBX1325 in patients with wet AMD.
The purpose of this study was to generate additional safety and effectiveness data in Indian neovascular age-related macular degeneration (nAMD) patients that more closely resemble the real-world population intended to be treated with brolucizumab. This study was conducted as part of the post-marketing regulatory commitment to the Indian Health authority.
Stargardt disease 1 (STGD1) is the most prevalent form of juvenile macular degeneration. It is caused by a rare, inherited autosomal recessive trait, leading to severe and irreversible blindness by the first or second decade of life. Earlier onset of the disease is related to a rapid vision loss, while patients with a later onset tend to have a better prognosis. This study will enrol subjects aged 12-18 years old with a confirmed clinical diagnosis of Stargardt disease type 1 (STGD1). This study will include 2 phases, the phase 1b portion is to determine the optimal dose for phase 2 based on the extent of retinol binding protein 4 (RBP4) reduction after 2 cycles of tinlarebant treatment. The phase 2 portion will evaluate the safety and efficacy of a single daily dose of tinlarebant over a 24-month treatment period.
Age-related macular degeneration (AMD) is a chronic and progressive eye disease and is one of the leading causes of vision impairment globally. AMD is referred to as either the dry or the wet type, where the wet type (also called neovascular-AMD or nAMD) is a later stage of the disease with neovascularization and retinal edema being the main attributes. This will usually cause subacute distortion or loss of central vision in patients. Since 2004, a successful treatment alternative for nAMD has been ocular injections with anti-VEGF (anti-Vascular Endothelial Growth Factor), causing the neovascularization and edema to regress and vision to improve. However, injections have to be repeated, usually requiring 8 injections or more during the first year of treatment. This can cause both a risk for serious adverse effects and is a significant financial drain on health care resources. Patients undergoing treatment are at risk for retinal edema recurrence. The time interval tolerated between injections is individual, and the accepted treatment strategy of today is to gradually, in a stepwise manner, increase the interval between injections. For some patients this extension is well tolerated, but for many patients relapse of proliferations and retinal edema will recur. With state-of-the-art technology OCT-A (optical coherence tomography-angiography) in combination with the clinically, well established examination method of OCT (optical coherence tomography), the project group will study the phenotypic vessel and tissue changes that occur in between injections. Furthermore, the investigators will measure cytokines, chemokines and growth factors in blood samples and the tear film during different treatment stages to see if any single factor is prognostic for poorer response to treatment or relapse. In the short term, the project group hope that the knowledge gained from this project could lead to a better understanding of the mechanisms behind nAMD neovascular relapse and to apply this to routine screening in the clinics. In the longer term, the project group hope that elucidating the physical mechanisms and molecular changes could enable new targeted therapies to be developed. Aim 1: To characterize the phenotype of vessels in relapsing nAMD patients and compare to those without relapse using OCT-A imaging Aim 2: To investigate retinal edema and choroidal thickness in correlation with neovascular changes of relapsing nAMD Aim 3: To measure cytokines, chemokines and growth factors in the tear film before and during treatment with anti-VEGF for nAMD With our main hypothesis being: Relapse of nAMD in patients occurs principally through reconfiguration and vasodilatation of persistent non-regressed vessels following anti-VEGF treatment, while fully regressed vessels remain dormant
The study involves the development of an algorithm for predicting anatomical and functional results of therapy with angiogenesis inhibitors in patients with retinal pigment epithelium detachments in neovascular age-related macular degeneration, based on primary optical coherence tomography of the macular zone and clinical data.
This multi-center study will enroll Adult subjects diagnosed with neo-vascular age-related macular degeneration (NV-AMD) in at least one eye at the time of enrollment. the subject study duration for this study is one day (2-3 hours). Each study site will have two NVHO devices and one Cirrus 5000 and the patients will be scand on the two NVHO devices and one Cirrus device as a part of the study flow. At the Study Visit, fluid must be present in approximately 280 study eyes and fluid must be absent from 20 study eyes. Each subject will only have one study eye. The fluid status will be determined by the investigator while reviewing an acceptable screening Cirrus OCT volume scan.

The purpose of this study is to evaluate incidence and prevalence rates of the study endpoints (pigmentary maculopathy [PM]/ pigmentary retinopathy [PR]/Any, PM/PR/ pentosan polysulfate sodium [PPS], and PM/PR/Non-PPS) in relation to PPS exposure, and in participants with interstitial cystitis (IC) but not exposed to PPS; changes in visual acuity (VA) over time; participant treatment journey leading to PPS treatment, and potential risk factors associated with the occurrence of PM/PR/PPS.
This was an open-label, single arm, multicenter, Phase IIIb study in subjects with (wet) nAMD, eligible for IVT aflibercept treatment.
This was the cross-sectional study to assess the period prevalence of IOI in patients with wet AMD who were treated with anti- VEGF agents (excluding brolucizumab) over a one-year period in 2019.
