There are about 1295 clinical studies being (or have been) conducted in Lithuania. 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 determine whether greater rectal cancer downstaging and regression occurs when surgery is delayed to 12 weeks after completion of radiotherapy/chemotherapy compared to 8 weeks. Hypothesis: Greater down-staging and tumor regression is observed when surgery is delayed to 12 weeks after completion of chemoradiotherapy compared to 8 weeks.
Degenerative aortic valve stenosis (AS) is the most common valve heart disease in the developed Western countries. The hemodynamic progression of AS occurs over time and leads to LV hypertrophy (LVH) as a compensation mechanism of the heart. Morphological changes such as increasing muscle fibre thickness, collagen volume, and interstitial fibrosis occur in AS patients. These changes result in left ventricular (LV) diastolic and systolic dysfunction and, consequently, to with AS related symptoms. When symptoms associated with AS appear, patients' prognosis is poor if surgical aortic valve replacement (SAVR) or a trans-catheter aortic valve implantation (TAVI) is not performed. Primary hypothesis of the research: fibrotic changes in the myocardium are related to immediate (in hospital) or long-term complications (MACE and all-cause mortality) in patients with severe AS. The goal of the study is to determine the prognostic implications of focal as well as diffuse myocardial fibrosis in patients with severe aortic valve stenosis.
The ChordArt System is a novel catheter based technology for mitral chordal replacement that enables controlled implantation of artificial mitral chords to treat mitral regurgitation with a minimally invasive approach. The implant is designed to allow transfemoral antegrade implantation.
Primary Objective: - To evaluate the long-term safety and tolerability of dupilumab in pediatric patients with asthma who participated in a previous dupilumab asthma clinical study. - To evaluate the efficacy of dupilumab in children of 6 to <12 years of age with uncontrolled persistent asthma in the Japan sub-study. Secondary Objectives: - To evaluate the long-term efficacy of dupilumab in pediatric patients with asthma who participated in a previous dupilumab asthma clinical study. - To evaluate dupilumab in pediatric patients with asthma who participated in a previous dupilumab asthma clinical study with regard to: - Systemic exposure. - Anti-drug antibodies (ADAs). - Biomarkers. - To evaluate the safety and tolerability of dupilumab in pediatric patients with asthma in the Japan sub-study - To evaluate dupilumab in pediatric patients with asthma in the Japan substudy with regard to: - Systemic exposure, - Anti-drug antibodies (ADAs), - Biomarkers
Some patients with limited disease small-cell lung cancer (LD SCLC) are cured after chemo-radiotherapy, but the majority relapse and die from their cancer. Better therapy is needed. Immunotherapy represents the largest advance in cancer therapy in recent years and has demonstrated promising activity in SCLC. In this study we will investigate whether atezolizumab prolongs survival in LD SCLC patients who have undergone chemo-radiotherapy.
The purpose of this study is to evaluate the efficacy and safety of mirikizumab as maintenance therapy in participants who completed as clinical responders in the prior 12-week induction study LUCENT-1 (NCT03518086).
The purpose of this study is to evaluate the safety and efficacy of Mirikizumab in participants with moderately to severely active ulcerative colitis (UC) who have had an inadequate response to, loss of response, or intolerant to conventional or biologic therapy for UC.
The purpose of this study is to evaluate the clinical efficacy (GALAXI 1), clinical and endoscopic efficacy (GALAXI 2 and GALAXI 3) and safety of guselkumab in participants with Crohn's disease.
This trial will evaluate the safety and efficacy of pembrolizumab (MK-3475) in combination with platinum doublet neoadjuvant chemotherapy (NAC) before surgery [neoadjuvant phase], followed by pembrolizumab alone after surgery [adjuvant phase] in participants with resectable stage II, IIIA, and resectable IIIB (T3-4N2) non-small cell lung cancer (NSCLC). The primary hypotheses of this study are that neoadjuvant pembrolizumab (vs. placebo) in combination with NAC, followed by surgery and adjuvant pembrolizumab (vs. placebo) will improve: 1) event free survival (EFS) by biopsy assessed by local pathologist or by investigator-assessed imaging using Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1); and 2) overall survival (OS).
The primary objectives of this study are: Part 1: To compare the overall survival (OS) of cemiplimab/chemo-f and cemiplimab/chemo-l/ipi versus platinum-based doublet chemotherapy in the first-line treatment of patients with advanced squamous or nonsquamous non-small cell lung cancer (NSCLC) with tumors expressing PD-L1 in <50% of tumor cells. Part 2: To compare the OS of cemiplimab/chemo-f with placebo/chemo-f in the first-line treatment of patients with advanced squamous or non-squamous NSCLC irrespective of PD-L1 expression. The key secondary objectives are: Part 1: To compare the progression-free survival (PFS) and objective response rate (ORR) of cemiplimab/chemo-f and cemiplimab/chemo-l/ipi versus chemo-f in the first-line treatment of patients with advanced squamous or non-squamous NSCLC and tumors expressing PD-L1 in <50% of tumor cells. Part 2: To compare the PFS and ORR of cemiplimab/chemo-f versus placebo/chemo-f in the first-line treatment of patients with advanced squamous or non-squamous NSCLC irrespective of PD-L1 expression.
