Filter by:This is a phase 1/2, open-label study designed to assess the safety and clinical activity of different belantamab mafodotin doses in combination with lenalidomide, dexamethasone and nirogacestat in patients with transplant ineligible newly diagnosed multiple myeloma. This will be a 2-part study. In part 1 participants will be enrolled in one cohort to receive belantamab mafodotin in combination with lenalidomide, dexamethasone and nirogacestat and will determine the recommended phase 2 dose (RP2D) to be further evaluated for safety and clinical activity in the dose expansion cohort. The RP2D dose will be used in future studies in the transplant-ineligible newly diagnosed multiple myeloma (NDMM) setting. In the dose expansion phase (Part 2) an expansion cohort will be treated with the RP2D. The expansion cohort will randomize participants (1:1) in two groups to evaluate two alternate dose modification guidelines for corneal AEs. Part 2 of the study will also evaluate an alternative dose modification guideline for corneal adverse events (AEs). Overall, approximately 36 participants will be enrolled in the study. Participant follow-up will continue up to 3 years after the last participant is enrolled (follow-up period range: 3-4 years). The estimated accrual period will be 12 months, corresponding to an approximate total study duration of 4 years.
Ocular surface photography is significantly limited in standardization and reproducibility. This reduces its applicability for clinical monitoring of acute or chronic disease. The innovative lens and illumination design of the CDL system aims to yield standardized high resolution photographs of the cornea and conjunctiva as required for clinical documentation, posing a significant clinical benefit of health care providers in the field of ophthalmology. Primary objectives: The primary objective of this study is to test the safety and feasibility of the CDL imaging system in a clinical routine setting. This will include the comparison of subjective contrast sensitivity testing post imaging, and the measurement of examination duration per imaging session, and the comparison of image lightness in mesopic versus photopic imaging. Secondary objectives: The secondary objective of this study is to compare the image quality of the device and repeatability of lateral resolution, dynamic range, hue, saturation, lightness, and image position between colour photographs from a state-of the art slit lamp camera and the CDL system. This is a monocentric, prospective, observational study. Patients with ocular surface disease of variable aetiology routinely assigned to ocular surface photography, following informed consent, will be imaged using state-of-the-art colour photography and the CDL imaging system. Pictures of each patient will be taken under several standardized conditions with both methods, subsequently analysed and compared by a Medical Image Processing Specialist.
A novel computerized visual acuity test was developed and tested on both healthy persons and patients with ocular conditions. Visual acuity outcomes of the computerized test will be compared to the Early Treatment Diabetic Retinopathy Study (ETDRS) in measures of reproducibility, accuracy and numbers of questions.
The purpose of this study is to evaluate visual outcomes in patients with complex corneas who have been previously implanted with the IC-8 IOL after cataract removal.
This is a phase 1/2, open label, study designed to assess the safety and clinical activity of different belantamab mafodotin doses in combination with daratumumab, lenalidomide and dexamethasone. The study will evaluate different doses of belantamab mafodotin in combination with daratumumab, lenalidomide and dexamethasone in 2 cohorts and will determine the recommended phase 2 dose (RP2D) to be further evaluated for safety and clinical activity in the dose expansion cohort. The RP2D dose will be used for future studies in the transplant ineligible newly diagnosed multiple myeloma setting. Overall, approximately 36 participants will be enrolled in the study. Participant follow-up will continue up to 3 years after the last participant is randomized. The estimated accrual period will be 12 months corresponding to an approximate total study duration of 4 years.
Cellular therapy of the corneal stroma with implantation of mesenchymal stem cells derived from autologous adipose tissue with or without a carrier (scaffold) composed by decellularized human donor corneal stroma is used in patients with corneal diseases such as corneal dystrophies, and keratoconus. For this purpose, the study planned to assess the enhancement of visual acuity, pachymetric, and aberrometric parameters with implantation of autologous mesenchymal adipose tissue-derived adult stem cells (ADASCs) alone, 120 µm thickness of decellularized or recellularized laminas with ADASCs. Three groups will be included in the study: (1) Implantation of a single dose of ADASCs alone without scaffold. (2) Implantation of decellularized human corneal lamina without ADASCs. (3) Implantation of the recellularized human corneal lamina with ADASCs.
Optical Coherence Tomography (OCT) image data will be evaluated for image quality and used to test post-processing algorithms to improve detection sensitivity for ophthalmic diseases.
Keratoconus is a progressive corneal disease characterized by asymmetric corneal thinning and structural changes in corneal collagen which leads to decrease in visual acuity due to myopic shift, irregular astigmatism or corneal scarring. Early detection of the disease in children aids in halting the progression and improve their quality of life. There is no consensus regarding the progression criteria of the disease, we aimed to assess the changes in corneal asphericity in children after corneal collagen crosslinking and investigate any possible correlation with progression criteria widely used.
PQ-504a-001 (Fuchs Focus) is an open-label, single-dose, exploratory study to evaluate safety, tolerability, and corneal endothelium molecular biomarker(s) in subjects with Fuchs Endothelial Corneal Dystrophy with Trinucleotide Repeat Expansion in the TCF4 gene (FECD3).
dry eye disease after corneal collagen cross linking affect ocular function leading to reduced vision, photophobia, glare, halos, and foreign body sensation.
