There are about 767 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.
This study will compare the efficacy and safety of molecularly-guided therapy versus standard platinum-containing chemotherapy in participants with cancer of unknown primary site (CUP; non-specific subset) who have achieved disease control after 3 cycles of first-line platinum doublet induction chemotherapy.
The purpose of this program is to evaluate the efficacy and safety of guselkumab in participants with Crohn's disease.
This randomized, active-controlled, multicenter, open-label, Phase III study is designed to investigate the efficacy and safety of alectinib compared with platinum-based in the adjuvant setting. Participants in the experimental arm will receive alectinib at 600 mg orally twice daily (BID) taken with food for 24 months. Participants in the control arm will receive one of the protocol specified platinum based chemotherapy regimens for 4 cycles. Following treatment completion, participants will be followed up for their disease until disease recurrence. At the time of disease recurrence, participants will enter a survival follow-up until death, withdrawal of consent or study closure, whichever occurs earlier.
This study will evaluate the safety and efficacy of Relamorelin compared to placebo in patients with diabetic gastroparesis. Patients will report daily severity scores of their diabetic gastroparesis symptoms.
A 46-week study to compare the efficacy of relamorelin with that of placebo in participants with diabetic gastroparesis (DG). At the end of the 40-week Treatment Period, participants will either continue on relamorelin or placebo for 6 additional weeks.
Observational, multi-centre, prospective study to investigate the feasibility of centralized TDM of moxifloxacin and levofloxacin in MDR-TB patients by determining turn-around time between sampling and receiving dosing advice. In addition, the effect of TDM will be evaluated by comparing treatment results of prospective patients receiving TDM with historical controls without TDM.
The objectives of Sub-Study 1 are to evaluate the efficacy, safety, and pharmacokinetics of risankizumab as induction treatment in subjects with moderately to severely active ulcerative colitis (UC), and to identify the appropriate induction dose of risankizumab for further evaluation in Sub-Study 2. The objective of Sub-Study 2 is to evaluate the efficacy and safety of risankizumab compared to placebo in inducing clinical remission in subjects with moderately to severely active UC.
The purpose of this study is to evaluate safety and efficacy of risankizumab in subjects with ulcerative colitis (UC) in subjects who responded to induction treatment with rizankizumab in a prior AbbVie study of risankizumab in UC. This study consists of three sub-studies: Substudy 1 is a 52-week, randomized, double-blind, placebo-controlled maintenance study; Substudy 2 is 52-week, randomized, exploratory maintenance study; and Substudy 3 is an open-label long-term extension study for subjects who completed Substudy 1 or 2.
The purpose of this study is to evaluate the clinical and virologic benefit of pimodivir in combination with Standard-of-Care (SOC) treatment compared to placebo in combination with SOC treatment.
In 1994, the WHO and UNICEF Joint Committee on Health Policy recommended Universal Salt Iodization as a safe, cost-effective and sustainable strategy to ensure sufficient intake of iodine by all individuals. However, it is still absent in Latvia. A recent countrywide study in 2013 shows iodine deficiency among pregnant women in Latvia: 81 % of pregnant women had UIC levels below the WHO recommended range of 150-250 mcg/g Cr. Because mild to moderate iodine deficiency during pregnancy can adversely affect fetal brain development, WHO-UNICEF and ICCIDD advise an increase in the recommended daily dosage of iodine to 250 mcg/day for pregnant women and breastfeeding women and 150 mcg/day for women in the preconception period. Data from a survey of the Latvian population indicate that approximately 100 mcg of iodine per day is consumed through foods and iodized salt. To meet the increased iodine requirement in pregnancy, pregnant women should take a supplement containing 150 mcg of iodine daily from the earliest time possible. A sudden increase in iodine intake in an iodine-deficient population may increase thyroid autoimmunity. It is evident that thyroid disease has multiple adverse effects during pregnancy and in the developing fetus especially in women with elevated serum anti-thyroid antibody titers. Studies have considered supplementing with selenium to reduce the risk of auto-immune thyroiditis/post-partum autoimmune thyroid disease. Of the 11 trials of selenium supplementation in patients with autoimmune thyroiditis, 7 have shown benefit with treatment for 6 months or longer. Aim of study is to approve that 150 mcg of iodine daily improves iodine status in pregnant women and iodine 150 mcg in combination with selenium 100 mcg daily reduce risk of thyroid autoimmunity. Hypothesis of study is that 150 mcg iodine daily during pregnancy improves iodine status. Iodine in combination with selenium is less associated with thyroid autoimmunity. Study design: Pregnant women are randomized for either 150 mcg iodine intake daily or 150 mcg iodine combined with 100 mcg selenium daily. Interventional group is compared with controls without particular iodine supplementation. Participants are asked to complete a questionnaire on dietary habits concerning iodine. Thyroid function (thyroid-stimulating hormone, free thyroxine) and thyroperoxidase antibodies (TPO-Ab) and urinary iodine are measured during first, second and third trimester of pregnancy and week 8 after delivery in both, intervention and control group.
