NCT ID: NCT05878977 Recruiting - Metastatic Melanoma Clinical Trials

Biomarkers in Immunotherapy of Melanoma

Start date: October 5, 2022
Phase: N/A
Study type: Interventional

Background: Immunotherapy has been successful in treating advanced melanoma, but a large proportion of patients do not respond to the treatment with immune checkpoint inhibitors (ICIs). Preclinical and small cohort studies suggest biomarkers from the primary tumor, stool and body fluids as markers of response. This prospective study will evaluate gastrointestinal microbiome (bacterial spices and virome) composition and exosomal mRNA expression of PD-L1 and IFNγ correlation with radiological response rates to ICIs treatment of advanced melanoma patients. Methods: Patients treated with immune checkpoint inhibitors as a first line treatment for metastatic melanoma are recruted to the study. Stool samples are submitted before the start of treatment, at the 12 (+/-2) week and 28 (+/-4) week, and at the event ( such as, suspected disease progression/hyperprogressio, immune related adverse event (irAE), etc). Peripheral venous blood samples are taken additionaly at the same time points for cytologic and molecular tests. Histological material from the tumor tissue is obtained before the start of immunotherapy treatment. Primary objectives are to determine whether human gastrointestinal microbiome (bacterial and viral) and exosomal mRNA expression of PD-L1 and IFNγ predict response to treatment with PD-1 and CTLA-4 inhibitors and are associated with occurrence of irAE in patients with metastatic melanoma at different time points. Response is evaluated radiologically with imaging methods in accordance with the irRECIST criteria. Conclussion: Despite the great success of the treatment of metastatic melanoma with immunotherapy, there remains a significant proportion of patients who do not respond to treatment or who develop severe adverse events during treatment. Identification of novel predictive and prognostic biomarkers for immunotherapy treatment response is therefore necessary. This study is the first to combine and investigate multiple potential predictive and prognostic biomarkers and its dynamics. The results could serve for a better and multi-level understanding of the various factors influencing immunotherapy treatment.

Start date: March 16, 2023
Phase: N/A
Study type: Interventional

The aim of the study is to investigate whether a serious smartphone game (called MOBI-CPR game) used in the home environment has an impact on the retention of adult basic life support knowledge and skills.

NCT ID: NCT05765864 Recruiting - Self-harm Clinical Trials

Self-harm Behaviour Among the Most At-risk Adolescents

SH-MARA
Start date: March 23, 2023
Phase:
Study type: Observational

In the proposed study, three objectives will be pursued: 1. To develop a method to identify more effectively the acute and long-term risk of adolescents with the most threatening self-harm behaviours. 2. To identify the factors that influence the risk of self-harm behaviours and the success of treatment/treatment of these behaviours in the most at-risk adolescents (changes in these factors). 3. Develop guidelines for more effective treatment of the most at-risk adolescents. For this purpose, a sample of approximately 200 young people who will be hospitalised for suicide risk (the most at risk in Slovenia) and an approximately equal number of healthy adolescents will be included. At inclusion, the presence of several factors will be assessed by reviewing demographic data, clinical diagnosis, self-assessment questionnaires and clinical psychological tests (CSSRS, B-NSSI-AT, ISAS, LPFS-BF2.0, BPFSC-11, TSCC, PAI, ECR-RS, DASA-YV, ASHRS), social assessment, and blood sampling for genetic analyses (DNA isolation, sequencing, nucleotide sequence recognition, quantification and evaluation of short tandem repeats, identification of methylation sites). Longitudinal tracking of autoaggressive events and heteroaggressive events during hospitalisation will be performed and recorded on an ongoing basis. The risk and protective factors of the adolescents most at risk will be compared with a control group of adolescents. The same factors will be reassessed in the most at-risk adolescents after 6 and 18 months of treatment as usual. The data will be collected in a data entry and storage system that will ensure the privacy of the data entered in accordance with the GDPR. This will allow the investigators to identify young people at particular risk of severe self-harm behaviour more reliably, to target them for more intensive and effective treatment, and thus to improve their safety, quality of life and prognosis in the short and long term.

NCT ID: NCT05764018 Recruiting - Hypoxia Clinical Trials

Caffeine and Hypoxia During Exercise in Males and Females

HypoCaff
Start date: March 6, 2023
Phase: N/A
Study type: Interventional

Several high-altitude destinations recommend their visitors to avoid caffeine, theoretically due to the associated diuresis which could contribute to acute mountain sickness. There is however no direct evidence for this association. In fact, caffeine ingestion is known to improve exercise performance at sea level, and may therefore help mountaineers during expeditions. Sport science research is largely conducted in male participants, and the findings from these studies are assumed to apply to the female population. Given the known sex differences in body composition, hormones, and other physiological factors, this may not be appropriate. It is therefore important to conduct research in women, to allow for female-specific recommendations.

NCT ID: NCT05754177 Recruiting - Clinical trials for Irritable Bowel Syndrome

Safety and Efficacy of a Probiotic Supplement in IBS-D

IBIS
Start date: June 6, 2023
Phase: N/A
Study type: Interventional

This study aims to assess the safety and efficacy of a single probiotic strain on symptom severity in adults with diarrhea-predominant Irritable Bowel Syndrome (IBS-D).

Participants will not have to undergo any additional clinical visits or tests except which are required in routine clinical care

NCT ID: NCT05735522 Recruiting - Clinical trials for Urinary Incontinence

Effectiveness of Magnetic Stimulation in the Treatment of Female UUI.

Start date: November 25, 2021
Phase: N/A
Study type: Interventional

Urinary incontinence is becoming an increasingly common health, social and economic problem. The prevalence of urinary incontinence is estimated at 55% of the entire female population. Urgency urinary incontinence (UUI) is the least common subtype of urinary incontinence but has debilitating symptoms that lead to a decrease in quality of life. Ultimately, the urogynegology field does not have many successful types of treatments for this specific subtype. Extracorporeal magnetic stimulation of the pelvic floor is a type of conservative management that produces a magnetic field, which induces controlled depolarization of the nerves, resulting in pelvic muscle contraction and sacral S2-S4 roots neuromodulation. Therefore, it relieves symptoms of UUI and improves quality of life. There was no randomized, sham-controlled study published that researched the effectiveness of magnetic stimulation in the treatment of UUI that evaluated the success with subjective and objective methods, such as urodynamic studies. The aim of this study was to assess the efficacy of magnetic stimulation in the treatment of urgency urinary incontinence.
