There are about 4372 clinical studies being (or have been) conducted in Greece. 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 primary objective of this study is to compare progression-free survival (PFS) in participants who receive sotorasib with platinum doublet chemotherapy versus participants who receive pembrolizumab with platinum doublet chemotherapy.
The aim of this study is to assess the ocular parameters of drowsiness in patients with diagnosed Obstructive Sleep Apnea Syndrome through objective methods of ocular imaging and subjective evaluation methods (questionnaire)
MODIFY is a randomized, open-labeled, and prospective study that will be conducted in multiple Intensive Care Units (ICUs) and departments of Internal Medicine across Greece. It aims to change the traditional approach for the management of severe infections by integrating the results of BCID2, Reveal Rapid AST, and PCT, to improve patients' outcomes. Early and precise identification of the underlying causative pathogen along with the fast acquisition of the antimicrobial sensitivity results may positively impact the uncontrolled antimicrobial prescription.
The goal of this clinical trial is to compare the gait of patients with hemiplegia, with or without the use of insole splint. The main questions it aims to answer are: Does the insole splint improve the gait of these patients? Does any difference exist in the use of muscles? Participants will have to walk in the gait analysis' aisle with and without the insole splint, using wireless EMG device.
The investigators hypothesize that Heterotopic Ossification (HO) formation can be suppressed if the application of a Continuous Passive Motion (CPM) device can be performed for a substantial amount of time. The investigators will use the following study design: a pilot study with 10 ICU patients receiving CPM and 10 matched cases which will follow a conventional physiotherapy program at the time of the conduction of the study. The comparison between the treatment and referent groups of the outcomes will prove the prophylactic power of CPM against HO.
The purpose of this study is to assess the real-world outcomes differences between apalutamide or enzalutamide plus androgen deprivation therapy (ADT) for the treatment of participants with metastatic hormone-sensitive prostate cancer (mHSPC).
The purpose of the present study is to compare the 1-year clinical, radiographic and microbiological outcomes and patients' satisfaction following surgical treatment of peri-implantitis after applying two different surface modification methods. Secondarily, analysis and comparison of the microbiological results of implants diagnosed and treated for peri-implantitis with healthy implants will be performed.
The role of human microbiota in neurological disorders via the "microbiota-gut-brain axis" is recently gaining increased attention due to the knowledge that gut microorganisms are involved in multiple gut and brain functions and metabolic pathways. The hypothesis of the present investigation is that changes of gut microbiota and their metabolic products may be a mechanism of the effectiveness of ketogenic diet in epilepsy. The aim of the present study is to investigate the changes of gut microbiota induced by the ketogenic diet and if certain populations of microorganisms are associated with better seizure control in epileptic children. This is a non-interventional study that will include epileptic children 2-18 years old eligible for ketogenic diet. The gut microbiome of participants will be examined in stools before and three months after the implementation of an olive oil- based ketogenic diet therapy. One of the participants' parents will also be included providing fecal sample for the examination of gut microbiome.
The aim of this study is to test whether lymphatic surgery provides better QoL (assessed with the Lymph-ICF-UL, (Lymphedema Functioning Disability and health questionnaire for upper limb lymphedema)) 15 months after randomization (and therefore about one year after surgery) compared to conservative treatment only for patients with chronic lymphedema (LE)
Hidradenitis suppurativa (HS) is an inflammatory skin disease that causes painful lesions in the axilla (underarm), inguinal (groin) and anogenital (anal/genital) regions. This study will assess how safe and effective upadacitinib is in treating adult and adolescent participants with moderate to severe HS who have failed to respond to or are intolerant of anti-tumor necrosis factor (TNF) therapy. Adverse events and change in disease activity will be assessed. Upadacitinib is an approved drug for ulcerative colitis, atopic dermatitis, rheumatoid arthritis, psoriatic arthritis, and axial spondylarthritis and is being developed for the treatment of HS. This study is "double-blinded", meaning that neither the trial participants nor the study doctors will know who will be given upadacitinib and who will be given placebo. This study is comprised of 3 periods. In Period 1, participants are randomized into 2 groups called treatment arms where each group receives a different treatment. There is a 1 in 2 chance that participants will be assigned to placebo. In Period 2, participants are placed into 6 different groups depending on their placement and results in Period 1. Period 3 is the long-term extension period where participants will continue treatment from Period 2. Approximately 1328 adult and adolescent participants diagnosed with HS will be enrolled in approximately 275 sites worldwide. Participants will receive oral tablets of upadacitinib or placebo once daily for 36 weeks in Period 1 and Period 2. Eligible participants from Period 1 and Period 2 will enter Period 3 and receive oral tablets of upadacitinib or placebo once daily for 68 weeks. Participants will be followed up for approximately 30 days. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular outpatient visits during the study. The effect of the treatment will be checked by medical assessments, checking for side effects and completing questionnaires.
