There are about 3194 clinical studies being (or have been) conducted in Portugal. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The aim of this study is to test the effect of cognitive stimulation (CS), applied individually and at home, on the overall cognitive functioning, emotional state, functionality, and quality of life (QoL) in adults with psychotic disorders. To this end, a randomised controlled clinical trial will be conducted in which selected participants will be randomly assigned to an individual intervention group using CS or a control group. The CS program is adapted from other existing protocol, composed of 32 sessions. Each session will last 45 minutes and will be held twice weekly. There will be four evaluation points (baseline, intra-evaluation - after 8 weeks of intervention, post-evaluation - after 16 weeks of intervention, follow-up - after 8 weeks of the end of intervention).
The authors hypothesize that in patients with iron deficiency anemia or gastrointestinal bleeding, pan-intestinal capsule endoscopy is a safe and well tolerated procedure that may improve diagnostic yield comparatively to the current standard invasive colonoscopy.
This is a randomized, double-blind, placebo-controlled, repeat-dose, multicenter trial. Participants will be screened within 6 weeks prior to the Baseline (Day 1) Visit. Approximately 300 participants who meet the trial eligibility criteria will be randomized on Day 1 in a 1:1:1 ratio to receive HZN-825 300 mg QD, HZN-825 300 mg BID or placebo for 52 weeks. The trial will include up to a 42-day Screening Period and a 52-week Double-blind Treatment Period. Participants will take their first dose of trial drug at the clinic and will participate in trial visits at Week 4 and every 6 weeks thereafter until Week 52. All participants who complete the Double-blind Treatment Period (Week 52) will be eligible to enter a 52-week extension trial (HZNP-HZN-825-302, NCT05626751). Participants not entering the extension trial will participate in a Safety Follow-up Visit 4 weeks after the last dose of trial drug.
The aim of this study is evaluate the effectiveness of the use of antidepressants in the treatment of muscle type temporomandibular disorders, with a sample of 60 to 80 participants.
This study is done to find out whether the medicine, semaglutide, has a positive effect on early Alzheimer's disease. Participants will either get semaglutide or placebo (a "dummy" medicine which does not contain any study medicine) - which treatment participants get is decided by an equal chance. The study will last for up to 173 weeks (about 3 years and 4 months). Participants will have 17 clinic visits and 1 phone call with the study doctor. The study includes various tests and scans. At 10 of the clinic visits participants will have blood samples taken. Participants must have a study partner, who is willing to take part in the study. Women cannot take part if pregnant, breastfeeding or plan to become pregnant during the study period. A cerebrospinal fluid (CSF) sub-study will be performed as a part of the study. The sub-study will be performed on a selection of sites based on their experience with CSF sampling and willingness to participate in this sub-study. The endpoints related to this sub-study are exploratory only.

This main long-term extension study is designed to evaluate the long-term safety and tolerability of faricimab 6 milligrams (mg) administered by intravitreal injection at a personalized treatment interval (PTI) to participants with neovascular age-related macular degeneration (nAMD) who enrolled in and completed one of the Phase III studies: GR40306 (NCT03823287) or GR40844 (NCT03823300), also referred to as the parent studies. Eligible patients who consent to participate in this main study will be enrolled upon completion of the end-of-study visit in the parent study. Additionally, there is a substudy that is being conducted. The aim of this substudy is to evaluate the impact of intravitreal faricimab on the health of the corneal endothelial cells in the study eyes of patients with nAMD to fulfill a U.S. Food and Drug Administration (FDA) post-marketing requirement. The fellow eyes of the same enrolled participants in the substudy will serve as the controls.
The study looks at how liraglutide works on participant's body weight. Researchers will look at how liraglutide can help children with obesity to lose weight. They will look at how much weight the children will lose, and if there are any side effects. Participants will either get liraglutide or placebo. Which treatment the participants get is decided by chance. Liraglutide is a new medicine for children, but it can already be prescribed by doctors to adults with overweight or obesity. The participant will get 1 injection every day. In addition to taking the medicine, the participants will have talks with the study staff about healthy food choices, how they can be more physically active and what can be done to help the participants to lose weight. The study will last for about 96 weeks (almost 2 years). The participants will have 18 clinic visits and 10 phone or video calls with the study doctor/staff. Participant will have blood samples taken, have 1 test to check the heart, 1 hand X-ray taken and must fill in a diary between some of the visits.
This study is open for men and women with a liver disease called nonalcoholic steatohepatitis (NASH) and liver fibrosis. The purpose of the study is to find out whether a medicine called BI 456906 helps patients with NASH and liver fibrosis. The study tests 3 different doses of BI 456906 to find the dose that helps best. Participants are put into 4 groups randomly, which means by chance. There are 3 groups that each receive a different dose of BI 456906 and there is 1 group that receives placebo. BI 456906 and placebo are given as an injection under the skin once per week. The placebo injection looks like the BI 456906 injection but does not contain any medicine. Participants are in the study for a little over 1 year (60 weeks). During this time, they visit the study site several times and have some video calls in addition. At the visits, the study doctors take different measurements. To see whether the treatment works, the doctors take a very small sample of liver tissue (biopsy) from each participant at the start and at the end of the study. They also examine the liver by ultrasound and MRI. The doctors also regularly check the general health of the participants.
This study compares insulin icodec (a new insulin taken once a week) to insulin degludec (an insulin taken once daily which is already available on the market) in people with type 2 diabetes. The study will look at how well insulin icodec taken weekly controls blood sugar compared to insulin degludec taken daily. Participants will either get insulin icodec that participants will have to inject once a week on the same day of the week or insulin degludec that participants will have to inject once a day at the same time every day. Which treatment participants get is decided by chance. The insulin is injected with a needle in a skin fold in the thigh, upper arm or stomach. The study will last for about 8 months. Participants will have 17 clinic visits and 13 phone calls with the study doctor. At 8 clinic visits participants will have blood samples taken. At 4 clinic visits participants cannot eat or drink (except for water) for 8 hours before the visit. Participants will be asked to wear a sensor that measures their blood sugar all the time in 3 periods for a total of 13 weeks (about 3 months) during the study. Women cannot take part if pregnant, breast-feeding or plan to become pregnant during the study period.
