Active clinical trials for "Infections"

The purpose of this study is to assess the efficacy of Bictegravir/FTC/TAF in patients with less of 100 days post HIV infection

To evaluate the safety of autologous CAR-T-cell therapy in individuals lived with HIV-1 infection, CAR T cells are infused after ex vivo expansion and transduction with lentiviral vectors encoding a broadly neutralizing HIV-1 scFv antibody.

This is a phase 2 study to evaluate the safety and tolerability of combination therapy with Albuvirtide (ABT) and 3BNC117 in virologically suppressed subjects with HIV-1 infection and explore the potential of viral suppression and viral reservoir clearance after analytical treatment interruption (ATI).

EBV-HLH and CAEBV are both caused by EBV infection, part of them can rapidly lead to a syndrome of severe, life-threatening hyper-inflammation, with poor prognosis. Currently, the most effective treatment remains unknown. This study is trying to evaluate the efficacy and safety of PD-1 monoclonal antibody as a first-line therapy for EBV-HLH and CAEBV.

EC CORONACOLCHI is a multicenter, double-blind and randomized clinical trial with two branches. Patients who meet all the inclusion criteria and none of the exclusion criteria will be randomized 1: 1 to be included in one of the following groups: Experimental group: colchicine for 2 weeks orally at the doses described, added to the standard treatment of COVID-19. Control group: placebo for 2 weeks orally added to standard COVID-19 treatment.

The purpose of this study is to evaluate efficacy of a 14-day concomitant therapy for the third-line treatment of Helicobacter pylori infection, and whether it is safe while maintaining an ideal eradication rates.

Although SARS-CoV-2 (Severe Acute Respiratory Syndrome-associated coronavirus) due to COVID-19 evolves poorly towards ARDS (Acute Respiratory Distress Syndrome) and death, there is to date no validated drug available for severe forms of COVID-19. Patients with COVID-19 undergo a drastic decrease of T lymphocytes (LT) count, while the remaining ones display an "exhausted" phenotype, due to immunosuppressive pathway activation among which the Programed cell Death 1 (PD1) receptor pathways. LT exhaustion is responsible for host anergy towards viral infection and leads to increased risk of severe forms of COVID-19. Moreover, while the number of systemic LT PD1+ correlates with poor prognosis clinical stages of COVID-19 infection, healing from COVID-19 associates with LT PD1 expression normalization. Chinese epidemiologic data identified clinical risk factors of poor clinical evolution (i.e. ARDS or death), among which is found obesity, similarly to observation previously obtained during H1N1 infection (flu virus). Obese persons display meta-inflammation and immune dysfunction, a condition similar to ageing, thus termed "Inflamm-aging", thus also used during obesity. Inflamm-aging, characterized by cytotoxic LT exhaustion and reduced NK cell (Natural Killer cell) cytotoxic function secondary to PD1 pathway activation, could contribute to the poor prognosis observed during cancer and infection in obese individuals. We hypothesize that the immunocompromised profile observed during obesity contribute to their vulnerability towards COVID-19. In cancer or certain infection diseases, NIVOLUMAB, an anti-PD1 monoclonal antibody, restores exhausted LT immunity. We thus hypothesize that NIVOLUMAB-induced immunity normalization could (i) stimulate anti-viral response also during COVID-19 infection and (ii) prevent ARDS development, which has previously been associated with low LT count concomitant with increased inflammatory cytokine production. This randomized controlled therapeutic trial, using an add-on strategy to usual standard of care, aims at demonstrating the efficacy and safety of NIVOLUMAB-induced cytotoxic LT normalization, to improve clinical outcomes in hospitalized COVID-19+ adult obese individuals with low LT, since they are at risk of poor prognosis. We postulate that NIVOLUMAB will increase the number of individuals able to stop oxygen therapy at D15

Study is prospective randomised multicentric. The primary objective of the study is to compare the efficacy of two first-line therapy regimens and two second-line therapy regimens (ie, after failure of first-line treatment) in patients with H. pylori infection. The secondary objective of the study is to determine the primary resistance of H. pylori to antibiotics in Slovenia.

This phase Ib trial evaluates the safety and most effective dose of a cytomegalovirus (CMV) pp65 peptide-loaded alpha-type-1 polarized dendritic cell (CMV-alphaDC1) vaccination in patients who are undergoing an allogeneic hematopoietic stem cell transplant. CMV is an opportunistic infection that can occur or reactivate after allogeneic hematopoietic stem cell transplant as a result of immunosuppression. The CMV-alphaDC1 vaccine is made of white blood cells that have been exposed to molecules called cytokines, as well as CMV proteins. Introducing these dendritic cells to the patients immune system may activate an immune response to CMV, protecting against infection or reactivation.

Background: Helicobacter pylori infection, which affects over 50% of the global population, is one of the most prevalent infectious diseases in the world. H. pylori infection causes chronic active gastritis and is associated with peptic ulcer, lymphoma of the mucosa-associated lymphoid tissue and gastric cancer. The colonization of H. pylori in the hostile gastric environment is determined by the complex interactions among bacterial, environmental and host factors. Because of the emergence of antibiotic resistance and adverse drug reactions such as diarrhea, the successful rates with standard triple therapy for H. pylori eradication are falling. Vitamin D or its analogues was found to induce autophagy in keratinocytes, macrophages, and various cancer cell types. Our preliminary findings indicated that 1α,25-dihydroxyvitamin D3 could induce cathelicidin expression and autophagy in cultured human gastric epithelial HFE-145 cells and reduced the intracellular survival of H. pylori in a co-culture system. It was also found that cathelicidin alone reduced the survival of drug-resistant strain of H. pylori. 1α,25-dihydroxyvitamin D3 also significantly reduced H. pylori colonization in mice, perhaps through the induction of cathelicidin in the stomach. These findings suggest that vitamin D not only could control H. pylori but also its drug-resistant strains in humans. Emerging evidence suggest that vitamin D might be a cost-effective prophylactic and possibly therapeutic antimicrobial agent for the control and eradication of H. pylori. Since vitamin D acts through mechanisms independent of standard antibiotics, it is expected that vitamin D will be equally efficacious for controlling and eradicating drug-resistant strains of H. pylori. The investigators herein propose that vitamin D in combination of standard antimicrobial therapeutics could improve the eradication rates of drug-resistant H. pylori.
