This study is a multi-center, single arm, open label, retrospective and prospective clinical data collection of CascadeTM, Non-Occlusive Remodeling Net, in adults with intracranial aneurysms, demonstrating the effectiveness and safety of the CascadeTM in providing temporary assistance for coil embolization of intracranial aneurysms. All consecutive eligible patients from all participating sites will be included in this clinical data collection. The relevant data of the coil embolization procedure will be collected via an eCRF system. Peri procedural data on the coil embolization procedure as well as discharge, 30 days and at 3-6 months status will be collected.
This is a randomised, double-blind, double-dummy, multicentre, dose-ranging clinical trial in subjects with vitamin D deficiency or insufficiency. Its general objective is to determine the efficacy and safety of different doses of calcifediol soft gelatin capsules (SGCs) compared to placebo.
The aim of the present study is to evaluate the efficacy of 5 mouthwashes, based on different ingredients, in the treatment of generalised gingivitis.
The purpose of this study is to demonstrate similar efficacy and safety between TVB-009 and Prolia® (denosumab)
The purpose of the study is to assess efficacy, safety and tolerability of treatment with zibotentan and dapagliflozin in combination and dapagliflozin 10 mg as monotherapy in participants with chronic kidney disease (CKD) with estimated glomerular filtration rate (eGFR) ≥ 20 mL/min/1.73 m^2, and urinary albumin to creatinine ratio (UACR) ≥ 150 mg/g and ≤ 5000 mg/g.
This Phase 2 study is conducted to investigate the safety and efficacy of runcaciguat in the treatment of diabetic retinopathy. To assess efficacy, the retinal morphology will be investigated by 7-field color fundus photography for central assessment of the diabetic retinopathy severity score, or DRSS. Two-step DRSS improvement at 24 weeks of treatment will be the primary efficacy endpoint. DRSS assessments are repeated after completion of 48 weeks of treatment. In addition, vision threatening complications will be recorded throughout the study and assessed as secondary efficacy endpoint.
The purpose of this study is to assess the safety and efficacy of Rodatristat Ethyl in pulmonary arterial hypertension (PAH) patients.
This study compares three doses of once daily semaglutide tablets in people with type 2 diabetes who were previously treated with other oral anti-diabetic medicines. Participants will be initiated on the lowest starting dose of 3 mg and gradually increased until they reach the final trial dose of 14 mg, 25 mg or 50 mg once daily semaglutide tablets. The final three doses will be randomized (i.e., decided by chance). Participants will be administered one tablet per day for 68 weeks. Women cannot take part if they are pregnant, breast-feeding or planning to become pregnant during the study period. Women who can get pregnant will be checked for pregnancy via urine tests. Once daily semaglutide tablets (3 mg, 7 mg and 14 mg) are approved for the treatment of type 2 diabetes in the US, in the EU and in some other countries, under the brand name Rybelsus®.
This is a two-arm, randomized, open label, two-center, controlled study to evaluate the safety and efficacy of Viusid plus Asbrip in patients with mild and moderate symptoms of respiratory illness caused by Coronavirus 2019 infection.
The purpose of the study was to evaluate the pharmacokinetics of a single oral dose of gilteritinib in male and female participants with severe renal impairment compared to healthy male and female participants with normal renal function. This study also evaluated safety and tolerability of a single oral dose of gilteritinib in male and female participants with severe renal impairment and healthy male and female participants with normal renal function. Part 2 of the study (mild and moderate renal impairment) was not conducted based on the final pharmacokinetic findings from part 1 (severe renal impairment).
