The aim of this trial is to evaluate the efficacy and safety of 2.5 and 5 mcg tiotropium compared to placebo over 12 week treatment period. Tiotropium inhalation solution will be delivered via Respimat inhaler and will be examined on top of maintenance inhaled corticosteroid treatment in patients with mild persistent asthma. Efficacy and safety will be assessed by measuring the effects on lung functions, effects on lung exacerbations, effects on asthma control and numbers of adverse events.
The purpose of this study is to determine if fluticasone furoate/vilanterol improves survival in patients with chronic obstructive pulmonary disease with a history of or increased risk of heart disease.
The primary objective was to evaluate the safety and efficacy of the treatment with BAY81-8973 for prophylaxis and treatment of breakthrough bleeds in children with severe hemophilia A. The secondary objectives were - To assess the safety and efficacy of BAY81-8973 during surgeries. - To assess incremental recovery of BAY81-8973. - To assess pharmacokinetic (PK) parameters in a subset of children (Previously treated patients [PTPs] and previously untreated patients [PUPs] / minimally treated patients [MTPs] - participation in PK sampling was voluntary and required consent).
The purpose of this study is to evaluate long term safety and tolerability of azilsartan medoxomil and chlorthalidone, once daily (QD), compared with olmesartan medoxomil and hydrochlorothiazide in hypertensive participants with moderate renal impairment.
The study evaluated the long-term safety of Desvenlafaxine Succinate (DVS) Slow Release (SR) during open-label treatment in adult outpatients who had a primary diagnosis of major depressive disorder (MDD). The study also evaluated the long-term response of subjects receiving DVS SR for clinical global evaluation, functionality, general well-being, pain, and absence of depressive symptoms (remission).
This multi-center study evaluates the safety and efficacy of vemurafenib in participants with BRAF V600 mutation-positive, surgically incurable, and unresectable Stage IIIC or IV (American Joint Committee on Cancer [AJCC]) metastatic melanoma.

The aim of the study is to asses the hydration status of incident peritoneal dialysis (PD) patients and its evolution over a period of four years, independent of the PD treatment modality (APD or CAPD) and the PD solution type.
The drug being tested is called VigantOL® oil - a very effective form of Vitamin D hormone supplement (cholecalciferol). Low levels of Vitamin D have been described to be associated with a higher risk of developing Multiple Sclerosis (MS), and it is known that up to 90% of patients with Multiple Sclerosis have Vitamin D deficiency. Rebif® is known to be an effective treatment for slowing down the progression of MS. The purpose of this research trial is to evaluate if VigantOL® oil on top of Rebif® has any benefit on the progression of MS compared to Rebif® and placebo. Disease activity will be assessed by clinical examination and Magnetic Resonance Imaging (MRI). The planned study treatment duration for each study participant is 48 weeks, and the study consists of a total of 8 visits. Study participants who are already passed Week 48 at the time of approval of Protocol Amendment 5 will have a study duration of 96 weeks and a total of 12 visits. During the study, the participant will undergo physical examination, neurological assessments, safety assessments, blood tests and urinalysis (including pregnancy tests).
