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.
This study evaluates the efficacy of Oral azacitidine versus single-agent Investigator's Choice Therapy in patients with Relapsed or Refractory Angioimmunoblastic T-cell Lymphoma.
Participating countries: Belgium Context: In June 2013, WHO notified that "a single dose of YF vaccine is sufficient to confer sustained life-long protective immunity against YF disease and that a booster dose is not necessary". . For HIV infected persons the recommendation was less stringent and the position paper concluded that hiv infected persons may "hypothetically, benefit from a second dose or booster dose ".1 Recently, WHO changed the recommendations about a booster dose of YF vaccine, based on the fact that serum neutralizing antibodies against YF are still at detectable levels after 20-35 years and probably lifelong in immunocompetent patients. Unfortunately, data on persistence of Neutralizing antibodies Titers (NT) in immunocompromised patients are missing and only few studies reported data about HIV-infected patients. Additional data are needed. Primary objective: To assess presence / persistence of Neutralizing Titers (NT) of antibodies after YF immunization in HIV-infected patients. Secondary objectives: 1. To identify risk factors for early and late waning of NT after YF immunization 2. To modelize kinetics of NT after YF immunization in different subpopulations of HIV patients, including population of young HIV patients infected vertically 3. To identify risk factors for absence of seroconversion in the year after YF immunization 4. To compare persistence of NT in HIV patients infected vertically or not vertically 5. To quantify seroconversion rate after YF vaccination Methodology / study design This study is a single arm, non randomized, cross-sectional, multicenter study in AIDS Reference Centers from Belgium. The maximum duration of the study for each patient will be 1 visit, consisting of: - the screening and inclusion visit (single visit V1) to check the patient eligibility, sign informed consent, perform the biologic tests necessary for the study and answer the questionnaire - whenever possible, an additional serum / plasma sample coming from serabank / plasmabank will be identified for each patient. This sample must have been taken during the year following YF immunization. - data about patient's HIV history has to be extracted from the HIV database or from patients' file Estimated enrolment 750 patients + 30 patients infected vertically with HIV Primary outcome Number of HIV patients with protective YF NT ≥ 1:10 at different timepoints after YF immunization Secondary outcomes 1. Number of patients with protective YF NT ≥ 1:10 in the year following YF immunization 2. Risk factors (demographics and immunovirological parameters, antiretroviral treatment) for absence of seroconversion in the year following YF immunization 3. Risk factors (demographics and immunovirological parameters, antiretroviral treatment) of early waning (before 10 years) of YF NT 4. Risk factors (demographics and immunovirological parameters, antiretroviral treatment) of late waning (after 10 years) of YF NT Eligibility Inclusion criteria 1. Infection with HIV-1 (vertical transmission or not) 2. Immunization with at least one injection of YF vaccine (Stamaril®,17D strain Rockefeller, Sanofi Pasteur) with proof of vaccine administration 3. Informed consent signed prior to any study procedure Exclusion criteria Inability to give informed consent Substudies - Whenever possible, an additional sera or plasma sample from the year following YF vaccine will be selected and analyzed to assess early seroconversion rate - Whenever possible, an additional sera or plasma sample from the year before YF vaccine will be selected and analyzed to assess seroconversion rate - In CHU Saint-Pierre, an additional cohort of patients infected vertically with HIV will be selected and will participate to the study
The purpose of this extension trial is to evaluate the long-term safety of tralokinumab.
The investigators recently observed airway inflammation and increased damage-associated molecular pattern (DAMP) level in sputum of children (age 11-12y) and adolescents (18-23y) from elite sport programs in Belgium with increased risk of bronchoconstriction upon extreme exercise. They here want to validate these findings in a cohort 13-18y.
Probiotics are defined as "live micro-organisms that, when administered in adequate amounts, confer a health benefit to the host" (Hill et al, 2014). These microbes are generally applied in the gastrointestinal tract via fermented food products or capsules. In previous research, the investigators isolated bacterial strains with potential probiotic properties for the upper respiratory tract based on in vitro laboratory tests, in vivo mice experiments and genome sequencing. In this study, the investigators want to deliver the Proof-of-Concept that the most promising isolated strain, Lactobacillus casei AMBR2 (LAMBR2) and the well-documented probiotic strain Lactobacillus rhamnosus GG (LGG) also have interesting properties in humans, i.e. that these strains are able to -temporarily- persist in the upper respiratory tract of healthy volunteers and CRS patients after daily nasal application via a nasal spray for 2 weeks. In addition, the investigators aim to explore whether the application of these strains has an impact on the nasopharyngeal microbiome via 16S rRNA amplicon sequencing and dedicated qPCR analysis. Therefore, bacterial DNA from nasal swabs will be isolated via commercially available DNA extraction kits, followed by Illumina MiSeq sequencing in order to identify the bacterial species present in these samples. Furthermore, the concentration of the Lactobacillus and specific pathogens will be monitored via qPCR.
To establish baseline prospective efficacy data of current FIX prophylaxis replacement therapy in the usual care setting of hemophilia B subjects, who are negative for nAb to AAV-Spark100, prior to the Phase 3 gene therapy study. To establish baseline prospective efficacy data of current FVIII prophylaxis replacement therapy in the usual care setting of hemophilia A subjects, who are negative for nAb to AAV6, prior to the Phase 3 gene therapy study. The enrollment for hemophilia A participants is completed. At this time participants are only being enrolled for hemophilia B cohort.
The study is a two-stage trial: 1. First stage (closed - 16 patients recruited in France): Phase I feasibility trial to evaluate the safety of the combination of Nivolumab + metronomic chemotherapy considering three possible metronomic chemotherapy regimens 2. Second stage (opened - 86 patients expected in France and Belgium): Phase II randomized controlled balanced 1:1 open-label trial comparing the efficacy of the metronomic chemotherapy regimen selected at the end of the previous stage (arm C: cyclophosphamide, capecitabine, vinblastine), with or without nivolumab. 3. "Trans-MetroPD1" ancillary sub-study is partially implemented since April 2022, and proposed to patients participating to second stage
Vine™ is a permanent carotid filter designed to provide protection against embolic stroke in people with atrial fibrillation. It is implanted bilaterally in the common carotid arteries from a thin needle under ultrasound guidance. The procedure is performed without general anesthesia and takes minutes. The safety, feasibility and tolerability of Vine™ will be evaluated. Patients who are eligible will receive Vine™ and will be followed-up for a year after device implantation.
This is a randomized, open label, multicenter phase III trial comparing the efficacy, safety, and tolerability of tisagenlecleucel to Standard Of Care in adult patients with aggressive B-cell Non-Hodgkin Lymphoma after failure of rituximab and anthracycline containing frontline immunochemotherapy.
This is an open-label, single-dose, multi-center, multinational trial to demonstrate the efficacy of AMT-061 and to further describe its safety profile. The study drug is identified as AAV5-hFIXco-Padua (AMT- 061). AMT-061 is a recombinant adeno-associated viral vector of serotype 5 (AAV5) containing the Padua variant of a codon-optimized human FIX complementary deoxyribonucleic acid (cDNA) under the control of a liver-specific promoter. The pharmaceutical form of AMT-061 is a solution for intravenous infusion administered at a dose of 2 x 10^13 gc/kg.
