There are about 13446 clinical studies being (or have been) conducted in Belgium. 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 objectives of the study, are to describe detection of SARS-CoV-2 in the semen of COVID-19 positive patients, the duration of positive semen and to investigate the impact on semen quality, thereby providing insights into the early impact on male reproductive function.
The phase II study evaluate a light dose escalation in a classical intraoperative PDT regimen mediated by 5-ALA-PpIX, in glioblastoma patients with access to full surgical removal of the contrast enhancement. This treatment will be performed in addition to the current reference treatment of glioblastoma: maximum removal surgery followed by radiochemotherapy according to the Stupp protocol.
This is a multicentre, open-label, parallel arms, phase IIII study that randomises patients with locally recurrent rectal cancer in a 1:1 ratio to receive either induction chemotherapy followed by neoadjuvant chemoradiotherapy and surgery (experimental arm) or neoadjuvant chemoradiotherapy and surgery alone (control arm)
The world population has been growing and aging dramatically, with a rising prevalence of dementia. Worldwide, around 50 million people have dementia, with 10 million new cases added every year. Despite the epidemic scale of dementia, until now no cure or disease-modifying therapy has been identified. Therefore, the World Health Organization (WHO) has recognized dementia as a public health priority. Several large studies have demonstrated that hearing impairment is associated with a greater risk of cognitive impairment. Hearing rehabilitation could potentially provide a disease-modifying therapy to delay cognitive decline. Although auditory behavioral research has not yet revealed a reliable indicator of early cognitive impairment, cortical-evoked auditory potentials (CAEP) have shown promising evidence as a non-invasive way to identify early-stage cognitive impairment. The peripheral vestibular apparatus is located in the inner ear and codes rotation and translation of the head to preserve a stable view. Increasing evidence suggests that bilateral vestibular function loss, also known as bilateral vestibulopathy (BVP), leads to hippocampal atrophy and reduced spatial cognitive skills, as well as structural and functional alterations in parieto-insular and parieto-temporal regions. Many studies have demonstrated that vestibular function declines with age. Vestibular dysfunction can be linked to reduced topographical orientation and memory and has been suggested as a risk factor to AD, due to increased risk of falling and deficits in activities of daily life (ADL). Our first aim is to study the effect of SNHL and vestibular decline on CAEP, spatial and non-spatial cognitive functioning and trajectories in cognitively healthy older subjects, as well as patients with mild cognitive impairment (MCI) and AD. Our second aim is to study if MRI brain volume changes can be observed in the hippocampus, entorhinal cortex, and auditory and vestibular key regions in these populations and correlate with CAEP and cognitive functioning. The expected outcome is important to society because it will provide data from a cognitive assessment protocol adapted for a potentially hearing-impaired population, objective outcome measures (incl. CAEP and MRI brain volume changes) to identify older subjects with SNHL and BVP at risk for cognitive decline, and will support screening and interventional studies to assess the impact of rehabilitation on slowing down cognitive decline.
The purpose of this study is to evaluate the efficacy of loncastuximab tesirine (ADCT-402) combined with rituximab compared to standard immunochemotherapy.
Haemophilia is a rare bleeding disorder, characterized by factor VIII (HA) or factor IX (HB) deficiency. The absence or the reduction of fVIII or fIX result in impaired thrombin generation and clot formation, causing excessive bleeding (mainly haemarthrosis). Osteoporosis is a systemic bone disease characterized by a low bone mineral density (BMD). A decrease of mean BMD has been described in haemophilic patients compared to healthy controls in several studies. So, osteoporosis could be an underestimated haemophilia-related comorbidity. None of the following risk factors (reduced physical activity, joint damage, vitamin D deficiency and /or hepatitis C virus (HCV) infection) has been retained as a cause of osteoporosis in haemophilic patients. Another hypothesis is that bone loss could be directly linked to fVIII or fIX and/or thrombin deficiency. The aim of this study is to evaluate the prevalence of the bone loss in HA and B patients, according to the type, the severity and the presence (or not) of a prophylactic treatment (depending on the age at which it was began) and to compare it to a control population. The investigators will also evaluate the relation between BMD and FVIII, fIX and thrombin potential.
Ten to 15 percent of couples in their reproductive lifetime face fertility problems which is defined by WHO as the absence of pregnancy after minimal 12 months of unprotected sexual intercourse. The three most frequent causes of subfertility are: sperm defects, ovulation disorders and tubal pathology. In order to exclude tubal pathology, tubal patency tests are performed under ultrasound guidance with foam (hysterosalpingo-foam sonography (Hyfosy)) or with contrast/water (hysterosalpingo-contrast sonography (Hycosy)). This trial will investigate whether tubal flushing with an oil-soluble contrast medium (OSCM) can increase the likelihood of a spontaneous conception after tubal patency testing with Hyfosy under ultrasound guidance compared to no additional flushing in a population of infertile women between 18 and 40 years of age with absence of pregnancy after 12 months of unprotected sexual intercourse or who have three cycles of donor insemination without pregnancy or three ovulatory ovulation induction cycles without pregnancy. The use of Lipiodol Ultra Fluide® is off-label in Hyfosy. This multicenter, randomised, open-label, comparative and pragmatic trial compares 2 arms which will be randomised 1:1: - Intervention group: Tubal flush with 5-10mL oil-soluble contrast medium (Lipiodol Ultra Fluide®, Guerbet, France) immediately after Hyfosy - Control group: No additional intervention after Hyfosy The study comprises a screening period of maximum 8 weeks (w-8 to d1), randomisation (w-8 to d1), a start study visit at which the Hyfosy is performed (d1) and a fertility treatment period of 6 months (d1-w26). If the woman is not pregnant at 6 months after Hyfosy, the follow-up will last till 12 months (w52). If the participant is pregnant at 6 months after Hyfosy, the follow-up will last till maximal 4 months after live birth or miscarriage. The primary endpoint is the occurrence of live birth, with the first day of the last menstrual cycle in which the patient conceives within 6 months after Hyfosy. Secondary endpoints consist of reproductive outcomes, gestational age at delivery, birth weight, neonatal mortality, major congenital anomaly, neonatal outcomes and thyroid function, pregnancy complications, number of complications during or immediately after the intervention, pain score of the Hyfosy and additional flush, thyroid function of the mother, general and disease-specific quality of life.
This study wil assess somatostatin receptor (SSTR) expression via the uptake of Gallium-68 labelled DOTA-conjugated SSTR targeting peptide using PET/CT imaging in multiple myeloma lesions pre-identified on 18F-FDG PET/CT in order to evaluate the feasibility of molecular radionuclide therapy in refractory and relapsing mutiple myeloma using the Lutetium-177 radiolabelled targeting peptide.
Starting in late 2019, the world is facing a pandemic with the SARS-CoV-2 virus. Patients with end-stage kidney disease and on treatment with renal replacement therapy are high risk patients, as they are unable to maximize social distancing. We plan to gather epidemiological data using two different diagnostic approaches. We will compare a symptom-driven screening, in combination with a nasopharyngeal swab plus computed tomography (clinical approach) against serological surveillance.
The TELE-RCT study is a prospective 2 arm randomized controlled trial recruiting patients with an implanted CRT device in Jessa Hospital Hasselt in Belgium.
