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.
The investigators study the feasibility of a novel method in oncology based on breath analysis with a nanosensors array for identifying gastric diseases. Alveolar exhaled breath samples collected from volunteers referred for upper endoscopy or surgery are analyzed using a custom-designed array of chemical nanosensors based on organically functionalized gold nanoparticles and carbon nanotubes. Predictive models are built employing discriminant factor analysis (DFA) pattern recognition method. Classification accuracy, sensitivity and specificity are determined using leave-one-out cross-validation or an independent blind test set. The chemical composition of the breath samples is studied using gas chromatography coupled with mass spectrometry (GC-MS). A pilot study is conducted first (enlistment of 160 subjects at the Department of Oncology, The First Affiliated Hospital of Anhui Medical University, The First Affiliated Hospital of Anhui Medical University, Hefei, Anhui, China.) The pilot study is followed by a large-scale clinical trial to confirm the preliminary results of the Chinese pilot study (enlistment of 800 subjects at the Digestive Diseases Centre GASTRO, Riga East University Hospital, 6 Linezera iela, LV1006 Riga, Latvia). 25% of the samples are used as independent blind test set. The samples are blinded by the medical team and are not disclosed until prediction of blind sample identity is complete. To further prove the diagnosis of GC from exhaled breath and seek the interrelationship among Breathomics, metabolomics and transcriptomics, saliva samples from about 200 patients are collected from volunteers referred for upper endoscopy or surgery are analyzed using Ultra-high-performance liquid chromatography-mass spectrometry (UHPLC-MS). Simultaneously, RNA sequencing are preformed on gastric cancer tissue samples and paracancerous tissue samples collected from same group of volunteers. The data of salivary metabonomics and transcriptomics were integrated and analyzed on the on Kyoto Encyclopedia of Genes and Genomes to confirm the diagnostic validity of salivary metabonomics.
This trial will facilitate access to denosumab for adults with advanced cancer who have participated in a denosumab phase 3 study until denosumab is approved and available for sale.
The purpose of this study is to evaluate the safety and effectiveness of the OMEGA Coronary Stent System for the treatment of subjects with a de novo atherosclerotic coronary artery lesion.
The purpose of this study is to evaluate the benefit of panitumumab in addition to best supportive care compared to best supportive care alone in patients with chemorefractory wild-type KRAS (Kirsten rat sarcoma viral oncogene homolog) metastatic colorectal cancer.
This is a study of safety, effectiveness, blood levels and tolerance of Ceftaroline fosamil in children with skin infections receiving antibiotic therapy in the hospital.
The purpose of this study is to assess the long-term safety, tolerability and efficacy of oral OPC-34712 as monotherapy in adults with schizophrenia.
The purpose of this study is to compare the effectiveness, safety and tolerability of three different doses of OPC-34712 with placebo in the treatment of acute schizophrenia in adults.
The purpose of this trial is to assess whether dulaglutide can reduce major cardiovascular events and other serious outcomes in persons with type 2 diabetes, when added to their anti-hyperglycemic regimen.
In this study several doses of ASP3652, given orally for 12 weeks, will be compared with placebo in the treatment of patients with Chronic abacterial Prostatitis / Chronic Pelvic Pain Syndrome.
The purpose of the protocol is to assess the rate of castration resistance, disease progression and overall survival over a 3-year period post-androgen deprivation therapy (ADT) induction in a study cohort of patients with advanced disease.
