There are about 1062 clinical studies being (or have been) conducted in Latvia. 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.
To demonstrate the safety and efficacy of the SurVeil Drug-Coated Balloon (DCB) for treatment of subjects with symptomatic peripheral artery disease (PAD) due to stenosis of the femoral and/or popliteal arteries.
The purpose of this study is to evaluate the efficacy of pembrolizumab (MK-3745) in the neoadjuvant (prior to surgery) or adjuvant (after surgery) treatment of previously untreated adults with gastric and gastroesophageal junction (GEJ) adenocarcinoma. The primary study hypotheses are that: - Neoadjuvant and adjuvant pembrolizumab plus chemotherapy, followed by adjuvant pembrolizumab is superior to neoadjuvant and adjuvant placebo plus chemotherapy, followed by adjuvant placebo in terms of Event-free Survival (EFS) based on Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1), and - Neoadjuvant pembrolizumab plus chemotherapy is superior to neoadjuvant placebo plus chemotherapy in terms of rate of Pathological Complete Response (pathCR) at the time of surgery. With Amendment 10, upon study completion, participants will be discontinued and may be enrolled in an extension study.
This is an international, multicentre, prospective, non-interventional, observational Registry of patients with X-Linked hypophosphatemia (XLH). The main objective of this XLH Registry is to collect data to characterise the treatment, progression and long-term outcomes of XLH in both adult and paediatric settings.
The purpose is to compare median two-year clinical outcome after OCT guided vs. standard guided revascularization of patients requiring complex bifurcation stent implantation
Prospective, single-arm, multi-center, international clinical investigation to evaluate the safety and effectiveness of the PQ Bypass System to access, deliver guidewires, and implant stent grafts for a percutaneous femoropopliteal (fem-pop) bypass.
The study consists of 4 sub-studies, as follows: - Sub-study 1 (Randomized, double-blind, placebo controlled study) to evaluate the efficacy and safety of risankizumab versus placebo as maintenance therapy in participants with moderately to severely active Crohn's disease (CD) who responded to intravenous risankizumab induction treatment in Study M16-006 or Study M15-991; - Sub-study 2 (Randomized, exploratory maintenance study) to evaluate the efficacy and safety of two different dosing regimens for risankizumab as maintenance therapy in participants who responded to induction treatment in Study M16-006 or Study M15-991; - Sub-study 3 (Open-label, long-term extension study) to evaluate long-term safety of risankizumab in participants who completed Sub-study 1, Sub-study 2, another AbbVie risankizumab Crohn's disease study, or participants who responded to induction treatment in Study M16-006 or Study M15-991 with no final endoscopy due to the Covid-19 pandemic. Additional objectives are to further investigate long-term efficacy and tolerability of risankizumab; - Sub-study 4 (Open-label On Body Injector (OBI) administration and long-term extension study) to evaluate patient-reported outcomes, efficacy, safety, tolerability, and pharmacokinetics of risankizumab administered via OBI in participants who are receiving maintenance treatment with risankizumab. - OL CTE to ensure uninterrupted care in accordance with local regulations until risankizumab is commercially available for participants who completed Sub-study 3, Sub-study 4.
This study includes two periods. The main objective of Period 1 is to compare the efficacy of upadacitinib 15 mg once daily (QD) and 30 mg QD versus placebo and versus adalimumab (Humira®) in participants with moderately to severely active psoriatic arthritis (PsA) who have had an inadequate response to non-biologic DMARDs (DMARD-IR). Period 1 is also designed to compare the efficacy of upadacitinib 15 mg and 30 mg QD versus placebo for the prevention of structural progression. The objective of Period 2 is to evaluate the long-term safety, tolerability and efficacy of upadacitinib 15 mg and 30 mg QD in participants who have completed Period 1.
The aim of this study is to evaluate the effect of routine FFR-guided complete revascularization with PCI compared to conservative management in patients with concomitant coronary artery disease who are undergoing TAVI.
This study is designed to evaluate the long-term safety and efficacy of Upadacitinib in participants with ulcerative colitis (UC) who have not responded at the end of the induction period in Study M14-234 Substudy 1, who have had loss of response during the maintenance period of Study M14-234 Substudy 3, or who have successfully completed Study M14-234 Substudy 3.
Coronary artery disease is often treated by implantation of permanent metallic stents.Coronary stents are required in the early healing phase after balloon dilatation but constitute a lifelong foreign body. New bioresorbable stents have been developed and are believed to improve long-term safety. The purpose of this study is to compare the safety and vessel healing after treatment of simple bifurcation lesions with the CE-marked bioresorbable stents Absorb and Desolve.
