A multicenter, randomized, double-blind, placebo-controlled, study to evaluate the efficacy and safety of oral ivermectin tablets versus placebo for COVID-19 prophylaxis
ATI-450 Plus Methotrexate (MTX) Versus Placebo Plus MTX in Patients with Moderate to Severe Active Rheumatoid Arthritis (RA) who have had an Inadequate Response to MTX Alone
This study will evaluate the clinical safety and the performance of the BTL-899 device (with its 899-AP-C-4 and 899-AP-C-5 applicators) during treatment of the flanks (also known as "love handles"). The study has a single-arm, open-label, interventional design. The subjects will be enrolled and assigned into one study arm and will be required to complete four (4) treatment visits. Both flanks will be treated simultaneously for 30 minutes per session. The flanks' fat thickness reduction will be documented by ultrasound. At the baseline visits health status will be assessed and, if needed, additional tests will be performed. Inclusion and exclusion criteria will be verified and informed consent will be signed. The treatment administration phase consists of four (4) treatment visits, delivered 5 - 10 days apart. At every treatment visit after the first, prior to the procedure, the participants will be assessed for adverse effects resulting from the previous treatment(s) with the BTL-899 device. Safety measures will include documentation of adverse events (AE) during and after the procedures. Follow-ups visits at 1 month and 3 months after the final treatment will be held.
This study is a randomized, double-blind, placebo-controlled, phase III, three-way crossover clinical trial evaluating the efficacy and safety of KVD900, in the treatment of hereditary angioedema attacks in adolescent and adult Patients
TAFFIX is a nasal powder spray that immediately creates a protective acidic barrier on the nasal mucosa against infection by inhaled viruses. The protective barrier lasts 5 hours. TAFFIX is approved as a medical device in Israel, intended for use to block inhaled viruses within the nasal cavity. In Europe, it is registered as a medical device indicated for use as a protective mechanical barrier against allergens and viruses (e.g., SARS-CoV-2) within the nasal cavity. TAFFIX is used as additional safety mean together with masks, hygiene, and social distancing. The study rationale is to evaluate whether daily use of TaffiX™ as prophylaxis will reduce the rate of SARS- CoV-2 infection and other upper respiratory infections, compared to the placebo control rate.
The purpose of this study is to evaluate the efficacy of NBI-1065845 compared with placebo in participants with MDD on improving symptoms of depression.
This study is open to adults with chronic kidney disease. People with and without type 2 diabetes can take part in this study. The purpose of this study is to find out whether a medicine called BI 690517 improves kidney function in people with chronic kidney disease when taken alone or in combination with a medicine called empagliflozin. In the first part of the study, participants take empagliflozin or placebo as tablets every day for 2 months. Placebo tablets look like empagliflozin tablets but do not contain any medicine. In the second part, participants are divided into several groups. Depending on the group, the participants then additionally take different doses of BI 690517 or placebo as tablets for 3.5 months. In this case, placebo tablets look like BI 690517 tablets but do not contain any medicine. Participants are in the study for about 6 months. During this time, they visit the study site about 12 times. Where possible, about 4 of the 12 visits can be done at the participant's home instead of the study site. The trial staff may also contact the participants by phone or video call. Participants collect urine samples at home. These samples are then analysed to assess kidney function. At the end of the trial the results are compared between the different groups. The doctors also regularly check participants' health and take note of any unwanted effects.
This is a randomized, open label, single-center, single-dose, four-period crossover clinical study to assess the pharmacokinetic profile and safety of a budesonide inhalation solution (AQ001S) compared to a budesonide inhalation suspension (comparator) in healthy volunteers.
This study is looking at semaglutide in combination with a potential new medicine (NNC0480-0389) in people with type 2 diabetes. The study is being conducted to see how well semaglutide, in combination with different doses of NNC0480-0389, work to lower blood sugar levels. Results from this study will be used to select the doses of the two medicines for other studies. Participants will either get: Semaglutide (a medicine doctors can already prescribe for treatment of type 2 diabetes) in combination with NNC0480-0389 (a potential new medicine) or placebo (a 'dummy' medicine that looks like the medicines but without any medicine). NNC0480-0389 alone, or semaglutide alone which treatment participant get is decided by chance. Participant will need to take 2-3 injections once every week during the study. One injection will be with semaglutide or placebo and 1-2 injections will be with NNC0480-0389 or placebo. Participant must inject the study medicines themself into the stomach, thigh, or upper arm. The study will last for about 41weeks. Participant will have 20 clinic visits. Participant will have blood samples taken at all clinic visits. At 3 clinic visits, participant will also have an electrocardiogram (ECG). This is a test to check participants heart. Participant will have their eyes checked before or at the start of the study and at the end of the study. Women can only take part in the study if they are not able to become pregnant
