There are about 1553 clinical studies being (or have been) conducted in Serbia. 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.
Female patients undergoing surgical treatment for early breast cancer and meeting the inclusion criteria for adjuvant breast radiotherapy were randomized into two groups. One group will receive adjuvant whole-breast radiotherapy in ultra-hypofractionated regimen of 26 Gy in 5 fractions. In contrast, the other group will receive partial breast irradiation with a dose of 26Gy in 5 fractions. The study's objective is to compare the effects of both breast radiotherapy protocols in terms of locoregional disease control and survival and to compare the adverse effects of radiotherapy between the two protocols. To determine if there is a correlation between different parameters and the efficacy and degree of toxicity for both protocols.
The goal of this randomized controlled double-blind parallel-group interventional trial is to evaluate the effects of dietary supplementation with molecular hydrogen and pyrroloquinoline quinone in elderly. The main questions it aims to answer are: (1) whether the supplementation affects biomarkers of mitochondrial function in serum, and (2) whether the supplementation affects cognition and brain metabolism. The participants will be subjected to take the dietary supplement during 6 weeks.
The purpose of this study is to investigate the pharmacokinetic (PK) similarity and efficacy, safety, and immunogenicity of ABP 206 compared with OPDIVO® (nivolumab) in subjects with resected advanced melanoma.
A experimental interventional prospective study will include patients with squamocellular carcinoma of the larynx surgically treated at the tertiary referral center. Clinical and demographic characteristics of the patients would be noted. The visual analog scale (VAS), Brief Pain Inventory questionnaire, Diagnosing Neuropathic Pain 4 (DN4) and Pain Detect Questionnaire were used for pain assessment. Questionnaire Quality of Life in Head and Neck Cancer Patients (QLQ - H&N35) was used to assess the quality of life in patients with surgically treated laryngeal carcinoma. The type and consumption of analgesics used after surgery was monitored. The analgesics were used according to WHO Ladder. Blood samples ware taken from the patients for the analysis of oxidative stress parameters and inflammation parameters before the operative treatment and after the operative treatment (1-2 postoperative day and 9-10 postoperative day). The concentrations of interleukin 1 (IL-1) and 6 (IL-6), glutathione peroxidase 1 (GPX1), superoxide dismutase 1 (SOD1) and malondialdehyde (MDA) in the serum were determined. The aim of the study will be to assess concentrations of inflammatory biomarkers (IL-1, IL-6) and oxidative stress factors (MDA, SOD, GPKS1) in postoperative course in surgically treated patients with laryngeal carcinoma and in possible complication occurrence. Also, their correlation to type and dosage of used analgesics, to pain assessment questionnaire scores and QOL questionnaire scores in surgically treated patients with laryngeal carcinoma will be assessed.
Researchers are looking for a better way to treat people who have macular edema secondary to retinal vein occlusion (RVO). In people with RVO, a blood vessel that carries blood away from the retina (vein) becomes blocked. The retina is the very back part of the eye. The blocked vein causes fluid and blood to leak into the retina and thereby causes a swelling of the macula (the center of the retina responsible for fine vision). This swelling is called macular edema. When a vein in the retina is blocked, the levels of a protein called vascular endothelial growth factor (VEGF) rises. VEGF helps the growth of new blood vessels. This can lead to macular edema and may cause the vision to become blurry. The study treatment intravitreal (IVT) aflibercept is given as an injection into the eye. It works by blocking VEGF and this can help repair vision problems related to RVO. IVT aflibercept is already available and is prescribed by doctors as the standard of care treatment for macula edema secondary to RVO. Standard of care is a treatment that medical experts consider most appropriate for a disease. Standard of care is given every 4 weeks in people with macula edema secondary to RVO. While repeated injections of aflibercept may prevent worsening of vision, it may place a burden on the patient. However, a higher amount (8 mg) compared to the standard of care (2 mg) of IVT aflibercept is being tested in studies. This higher amount could be given less often. The amount of IVT aflibercept given is measured in milligrams, also known as mg. The main purpose of this study is to learn how well a higher amount of the study treatment aflibercept works in people with macular edema secondary to RVO. To answer this, researchers will measure changes in vision called best corrected visual acuity (BCVA) in the study participants between study start and after 36 weeks of treatment. Changes will then be compared between those participants who received the higher amount of IVT aflibercept and those that received standard of care. To learn how safe the study treatment is in the participants, the researchers will count the number of participants from study start and up to 64 weeks later that have: - adverse events - serious adverse events "Adverse events" are any medical problems that the participants have during a study. Doctors keep track of all adverse events that happen in studies, even if they do not think they might be related to the study treatments. An adverse event is considered "serious" when it leads to death, puts the participants' lives at risk, requires hospitalization, causes disability, causes a baby being born with medical problems or is otherwise medically important. Dependent on the treatment group, the participants will either receive the higher amount of aflibercept or standard of care as an intravitreal injection for up to 60 weeks. The study will consist of a test (screening) phase, a treatment phase and an end of study phase. Each participant will be in the study for up to 64 weeks. One visit to the study site is planned during the screening phase, followed by visits approximately every 4 weeks (16 in total) during treatment and one visit at the end of the study. During the study, the study doctors and their team will: - check patients' eye health using various eye examination techniques - measure patients' eye vision (BCVA) - take blood and urine samples - do physical examinations - check vital signs - examine heart health using electrocardiogram (ECG) - do pregnancy tests in women of childbearing age In addition, participants will be asked to fill a questionnaire on vision-related quality of life.
This is a prospective, randomized, single blinded, controlled clinical trial designed to compare the clinical effects of sedation with dexmedetomidine versus propofol in patients undergoing cardiac surgery.
Systemic Lupus Erythematosus (SLE) is an immune-mediated disease associated with inflammation of multiple organ systems. This study will assess how safe and effective upadacitinib is in treating adult participants with moderately to severely active SLE. Adverse events and change in the disease activity will be assessed. Upadacitinib is an approved drug for rheumatoid arthritis, psoriatic arthritis, and axial spondylarthritis and is being developed for the treatment of SLE. This study is "double-blinded", which means that neither the trial participants nor the study doctors will know who will be given upadacitinib and who will be given placebo (does not contain treatment drug) . This study comprised of 3 sub studies. In Study 1 and Study 2, study doctors put the participants in 1 of the 2 groups, called treatment arms. Each group receives a different treatment. There is a 1 in 2 chance that participants will be assigned to placebo. Eligible participants from Study 1 and Study 2 will enter Study 3 at week 52 to receive specific doses of upadacitinib based on their disease activity and their original treatment assignment in Study 1 or 2. Approximately 500 participants diagnosed with SLE will be enrolled in each of the Study 1 and Study 2 in approximately 320 sites across the world. Participants will receive oral tablets of upadacitinib or matching placebo once daily for 52 weeks in Study 1 and Study 2. Eligible participants from Study 1 and Study 2 will receive oral tablets of upadacitinib once daily for 52 weeks in Study 3. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, checking for side effects and completing questionnaires.
This study is to evaluate the efficacy and safety of PLS240 in patients with hemodialysis-dependent end stage kidney disease (ESKD) and secondary hyperparathyroidism (SHPT). The study consists of two phases. First, a placebo-controlled, double-blind phase where patients will be randomly assigned to either receive dose-titrated PLS240 or matching placebo for 27 weeks. After the completion of the double-blind phase, patients will be eligible to enroll in the open-label extension phase, where they will receive dose-titrated PLS240 for an additional 26 weeks. Throughout the duration of the study, patients will be expected to attend multiple study visits where an investigator will collect blood, preform electrocardiograms (ECGs) and physical exams, and further assess the safety and efficacy of PLS240.

Rheumatoid Arthritis (RA) is a chronic inflammatory disease causing pain, stiffness, swelling and loss of joint function. This study will assess how safe and effective upadacitinib is in treating RA when compared to adalimumab in adult participants with inadequate response or intolerance to one TNF-inhibitor who are on a stable dose of methotrexate (MTX). Adverse events and change in disease activity will be assessed. Upadacitinib is an approved drug for the treatment of RA. This study is double-blinded means that neither the participants nor the study doctors will know who will be given upadacitinib and who will be given adalimumab. Study doctors put the participants in 1 of the 2 groups, called treatment arms randomly, to receive either upadacitinib or adalimumab. There is 1 in 2 chance that participants will receive adalimumab. Each group consists of 2 periods. Approximately 480 participants diagnosed with RA will be enrolled in approximately 250 sites across the world. Participants will receive the oral upadacitinib once daily and matching adalimumab placebo every other week, or the subcutaneous adalimumab every other week and matching upadacitinib placebo once daily during Period 1. Eligible participants will continue to receive same study treatment in Period 2 as assigned in Period 1 and will be followed for 30 days and 70 days. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, checking for side effects and completing questionnaires.
