Protocol AXR201701 is a multicenter, double-masked, vehicle-controlled, randomized, parallel group study carried out in 2 stages (Stage 1: AXR-159 Ophthalmic Solution (30 mg/mL or 50 mg/mL); Stage 2: AXR-159 Ophthalmic Solution (3 mg/mL, 30 mg/mL or 50 mg/mL) in approximately 430 patients diagnosed with dry eye disease (DED).
Evaluate the tolerability, efficacy and safety of VOS versus Restasis® in subjects with mild to moderate Dry Eye Disease (DED).
Hypertension is common side effect of Cushing Syndrome (CS): in patients with endogenous CS and those treated with glucocorticosteroids (GCs). The impact of the intravenous GCs therapy on blood pressure (BP) remains unclear. According to the European Group On Graves' Orbitopathy (EUGOGO), patients with active, severely symptomatic and sight-threatening Graves' orbitopathy (GO) should be treated with high dose intravenous methylprednisolone (IVMP) pulses. There are, however, reports of fatal side effects that may be associated with this therapy (e.g.: pulmonary embolism, myocardial infarction, severe cerebrovascular events, acute liver damage and sudden death). For this reason, the cumulative dose of IVMP should not exceed 8 g within each treatment course, and pulses should not be given on consecutive or alternate days, except for the case of dysthyroid optic neuropathy. A consensus on the monitoring of patients during and after IVMP pulse administration is not yet established. What is more, there is lack of paper regarding pattern of blood pressure at various time points during and after ivGCs administration. Thus, the investigators decided to evaluate acute changes of N-terminal pro-brain natriuretic peptide (NT-proBNP) as a marker of hemodynamic stress and to monitor BP before, during and after IVMP pulse administration. All of patients were treated routinely according to EUGOGO recommendations with standard doses of methylprednisolone with standard recommended schedule. Inclusion criterion for the therapy was according to EUGOGO guidelines active, moderate-to-severe and active GO (12 pulses of IVMP 6x0.5g followed by 6x0.25g every week).
Optical coherence tomography (OCT) is an imaging modality, first described in 1991, that provides cross-sectional images of the eye in a non-invasive manner. OCT is analogous to ultrasonography but measures the "echoes" of light waves rather than sound and, as a result, generates extremely high-resolution images (~5 μm axial resolution). Although OCT has already proven revolutionary in ophthalmology, current OCT systems are large, expensive, and require skilled personnel for image acquisition and interpretation. Furthermore, current OCT systems are limited to examination of specific regions of single eyes - for example, separate devices are typically required for anterior segment (e.g., cornea) versus posterior segment (e.g., retina) imaging. A new form of OCT imaging has recently been developed - so-called "binocular" optical coherence tomography (OCT) (Envision Diagnostics, Inc., California).1,2 Binocular OCT addresses many of the short-comings of conventional OCT devices. Binocular OCT extends the application of OCT devices beyond that of simple, cross- sectional imaging to a diverse array of diagnostic tests. The binocular design also removes the need for additional personnel to perform testing (i.e., the device can be self-operated in an automated manner), and allows for novel testing to be performed that is not possible with monocular imaging. In particular, binocular OCT devices have the potential to perform automated, quantitative pupillary measurements - an entirely novel application for this imaging modality, plus also adds a number of unique capabilities. In particular, binocular OCT removes the need for additional personnel to acquire the images by enabling patients to align the optical axes of the instrument with the optical axes of their own eyes. The system also employs recently developed "swept-source" lasers as its light source, allowing it to see deeper into the eye than conventional OCT systems. Finally, binocular OCT systems allow image capture from both eyes at the same time. This "simultaneous" ocular imaging extends the range of diagnostic testing possible, allowing for features such as pupillometry and ocular motility. The greatly increased range of imaging for these lasers enables the entire depth of eye tissue to be captured in just a few sequences of images - so- called "whole eye" OCT or "OCT ophthalmoscopy". In this study, the investigators aim to explore the unique imaging features of the binocular OCT to describe novel features across a range of diseases. The repeatability of quantifying various parameters in the images acquired using the system will be assessed.
The alterations of coagulation and fibrinolysis parameters have been described in patients with endogenous Cushing's syndrome (CS) and those treated with glucocorticosteroids (GCs). The change in hemostatic process is associated with an increased risk of venous thromboembolic events (VTE) and pulmonary embolism (PE). Anticoagulation prophylaxis reduces thromboembolic complications in endogenous and exogenous hypercortisolism. The impact of the intravenous GCs therapy on hypercoagulability, however, remains unclear and perplexing. According to the European Group On Graves' Orbitopathy (EUGOGO), patients with active, severely symptomatic and sight-threatening Graves' orbitopathy (GO) should be treated with high dose intravenous methylprednisolone (IVMP) pulses. There are, however, reports of fatal side effects that may be associated with this therapy (e.g.: PE, myocardial infarction, severe cerebrovascular events, acute liver damage and sudden death). For this reason, the cumulative dose of IVMP should not exceed 8 g within each treatment course, and pulses should not be given on consecutive or alternate days, except for the case of dysthyroid optic neuropathy. Nevertheless, even smaller cumulative therapy may be associated with fatal cardiovascular complications. Hence the aim of our study was to evaluate the effects of IVMP therapy on hemostatic process in patients with GO. All of patients were treated according to EUGOGO recommendations with standard doses of methylprednisolone with standard recommended schedule. Inclusion criterion for the therapy was according to EUGOGO guidelines moderate-to-severe and active GO (12 pulses of IVMP 6x0.5g followed by 6x0.25g every week).

Subjective and objective evaluation of the efficacy and tolerability of preservative-free "Ectoin® Eye Spray - Colloidal" and comparison of the efficacy and tolerability between "Ectoin® Eye Spray - Colloidal" and Tears Again® in patients with mild-moderate dry eye disease
The prevention and treatment of diseases via artificial intelligence represents an ultimate goal in computational medicine. Application scenarios of the current medical algorithms are too simple to be generally applied to real-world complex clinical settings. Here, the investigators use "deep learning" and "visionome technique", an novel annotation method for artificial intelligence in medical, to create an automatic detection and classification system for four key clinical scenarios: 1) mass screening, 2) comprehensive clinical triage, 3) hyperfine diagnostic assessment, and 4) multi-path treatment planning. The investigator also establish a telemedicine system and conduct clinical trial and website-based study to validate its versatility.
The study is aimed at assessing IGF-1R-Abs in patients with Graves' disease, with or without GO, compared with healthy subjects and patients with autoimmune thyroiditis in a cross-sectional investigation.
