There are about 4372 clinical studies being (or have been) conducted in Greece. 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 purpose of this study is to estimate the incidence rates of malignancy, excluding non-melanoma skin cancer (NMSC), venous thromboembolic events VTE (deep venous thrombosis [DVT] and pulmonary embolism [PE]), NMSC, major adverse cardiac events (MACE), progressive multifocal leukoencephalopathy (PML), infections, hospitalization and specific antibiotic or antiviral treatment, lung cancer, lymphoma, herpes zoster, myocardial infarction (MI), gastrointestinal (GI) perforations, fractures, surgery for UC and death; through 4 sub-groups: adult patients with UC who initiate tofacitinib in the course of routine clinical care compared to other medications approved to treat UC.
The aim of this study will be to investigate the effect of opioid-free induction versus opioid-based induction on hemodynamic response and nociception level index during elective operations
The purposes of this multicenter retrospective cohort study are to determine the residual nodal burden in patients with isolated tumor cells detected in the SLN or the clipped node after NAC and to determine oncologic outcomes in this group of patients after ALND or nodal RT or observation.
The primary objective of this study is to compare the postoperative visual acuity curves of patients that underwent one of the following surgical procedures: Insertion of an extended depth of focus intraocular lens with digital assistance and insertion of an extended depth of focus intraocular lens without digital assistance.
Researchers are looking for a better way to treat people who have advanced non-small cell lung cancer (NSCLC) with specific genetic changes called human epidermal growth factor receptor 2 (HER2) mutations. Advanced NSCLC is a group of lung cancers that have spread to nearby tissues or to other parts of the body or that are unlikely to be cured or controlled with currently available treatments. HER2 is a protein that helps cells to grow and divide. A damage (also called mutation) to the building plans (genes) for this protein in cancer cells leads to a production of abnormal HER2 and therefore abnormal cell growth and division. The study treatment, BAY 2927088, is expected to block the mutated HER2 protein which may stop the spread of NSCLC. The main purpose of this study is to learn how well BAY 2927088 works and how safe it is compared with standard treatment, in participants who have advanced NSCLC with specific genetic changes called HER2 mutations. The study participants will receive one of the study treatments: - BAY 2927088 twice every day as a tablet by mouth, or - Standard treatment in cycles of 21 days via infusion ("drip") into the vein. The treatment will continue for as long as participants benefit from it without any severe side effects or until they or their doctor decide to stop the treatment. During the study, the doctors and their study team will: - take imaging scans, including CT, PET, MRI, and X-rays, of different parts of the body to study the spread of cancer - check the overall health of the participants by performing tests such as blood and urine tests, and checking - heart health using an electrocardiogram (ECG) - perform pregnancy tests for women - ask the participants questions about how they are feeling and what adverse events they are having. An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events, irrespective if they think it is related or not to the study treatment.
The aim of the study is to evaluate the effectiveness of calcium hydroxide as an intracanal medicament in the clinical and radiographic healing of periapical tissues in teeth diagnosed with symptomatic apical periodontitis. This evaluation will be conducted after multiple visit endodontic treatment. The follow-up sessions will be programmed from 6 to 24 months postoperatively. Postoperative pain will also be considered as a secondary outcome. Participants will be asked to rate their pain level on a numerical scale from 0 to10 before and after each session of endodontic treatment. Additionally, the use of analgesics after the procedure will be measured and the incidence of flare-ups will be evaluated. Two study groups will be formed to undergo multiple-visit endodontic treatment. The intervention group will receive intracanal medication of calcium hydroxide, while the control group will have the root canal left empty between appointments.
The study is designed to evaluate the long-term safety and efficacy of GSK1070806 in participants with moderate-to severe atopic dermatitis, who have completed phase 2b parent GSK atopic dermatitis (AtD) study (NCT05999799).
When some people have their large bowel removed, a surgeon can make a "pouch" from part of the small bowel to connect it to the back passage (anus). Pouchitis is when the pouch becomes inflamed (swollen) or infected. The main aim of this study is to find out if vedolizumab improves pouchitis symptoms and pouch inflammation. Other aims include to find out if vedolizumab is well tolerated and if it causes any medical problems (adverse events or side effects) and to look for any changes in the well-being of participants during their treatment with vedolizumab. Participants will receive up to 6 infusions of vedolizumab. First 3 infusions are in first 6 weeks (Day 1, Week 2 and Week 6). Participants who are getting benefit may continue with the treatment for up to 7.5 months (30 weeks) in total. After completing treatment with vedolizumab, participants will visit their clinic for a health check at Week 34. One final health check will be scheduled 4.5 months (18 weeks) after the last vedolizumab infusion. Participants who continue to benefit from their treatment at the end of this study will be invited to continue treatment with vedolizumab in another clinical study (Vedolizumab-3042).
The aim of this study is to examine the effects of chocolate on the vascular function of endurance runners through a crossover study involving male runners consuming both dark and white chocolate.
Prevention is essential for reducing cancer-related mortality. However, people with mental ill-health often face difficulties in accessing cancer prevention services. The EU-funded CO-CAPTAIN project aims to co-adapt and implement the Patient Navigation Model for primary cancer prevention in this underserved population. This evidence-based and patient-centred intervention aims to support patient empowerment through removal of systemic barriers, provide social support and promote timely access to primary prevention services.
