Active clinical trials for "Communicable Diseases"

Acute respiratory infections (ARI) are one of the most frequent reasons for hospital admission and antibiotic use, and can be caused by a broad range of pathogens, including respiratory viruses with proven epidemic potential, e.g. influenza and coronaviruses. The POS-ARI-ER study will focus on describing the different routine diagnostic and therapeutic practices in the work-up and treatment of ARI, as well as clinical outcomes across the patient population. In addition, POS-ARI-ER aims to characterise both the adult patient population with ARI presenting to acute hospital settings in Europe, and the aetiology of ARI in these patients.

With the advent of direct acting antiviral (DAA) treatment in 2013, HCV elimination has become feasible. Still, achieving HCV elimination in resource-limited countries appears to be arduous as several challenges need to be addressed. In remote settings, absence of HCV VL testing to identify those who require DAA and to monitor DAA success is a first issue. As of today, HCV VL testing is still restricted to central facilities in major cities. Blood sampling using DBS is an appealing option to allow HCV VL monitoring in remote settings as this option is inexpensive, does not require a cold chain for storage and transportation of the samples and can be implemented rapidly. A second issue is DAA access that remains scarce due to logistical and financial limitations. However, more affordable generic DAA, some of them being WHO pre-qualified, are now available. Vietnam is amongst the 20 countries with the highest HCV burden with an estimate of 1.5 million chronic HCV-infected people (HCV prevalence: 1.1%). As observed in many other settings, HCV prevalence is higher among vulnerable populations such as HIV-infected individuals and people who inject drugs (PWID). Vietnam has the will to increase access to DAA in the whole country. However, in remote settings, only some clinical sites will be allowed to dispense DAA. Discussions with the MoH of Vietnam brought to our knowledge that not all clinical sites caring for HIV patients and providing ART will dispense DAA. Thus, some HIV-HCV co-infected patients will be followed in clinical sites where they will receive both antiretroviral therapy and DAA, while some other patients will continue to be followed for HIV in their usual clinical site but will be asked to visit another clinical site for HCV care and to receive DAA. We anticipate that the proportion of patients who will comply with the 12-week DAA will be lower in patients followed for HIV and HCV in two clinical sites than in those followed in a single clinical site.

Study to assess the efficacy and safety of XC8, film-coated tablets, 10 mg in comparison with placebo in patients with dry non-productive cough against acute respiratory infection.

Tumor resection and prosthetic replacement have become the treatments of choice for malignant bone tumors. Infections are the main cause of failure of limb salvage surgeries. Therefore, treatment of infections around prostheses after limb salvage is important, but is also challenging. Our research team designed a "domino" sequential treatment plan to treat postoperative infections around tumor prostheses and evaluated its efficacy.

The study is planned to evaluate the therapeutic efficacy and safety of Ingavirin®, syrup, 30 mg/5 ml, in the treatment of influenza or other acute respiratory infections in children from 6 months to 2 years compared with placebo.

The human microbiota corresponds to an extremely rich and varied set of microorganisms that colonize our various epitheliums from birth, including the intestine, lungs and skin, where they interact continuously with our immune system. Changes in microbial composition and function, termed dysbiosis, have been linked to alterations in immune responses and to disease development, such as psoriasis. Recent research has shown that the gut microbiota can condition the therapeutic response to checkpoint inhibitors and that fecal microbiota transplant overcomes resistance to these therapy, suggesting a direct role for the microbiota in the ability to shape a therapeutic immune response. Antibiotic exposure during the course of cancer therapy negatively correlates with patients' response to anti-PD-1 treatment response, thus highlighting the link between the enrichment of specific microbial taxa in intestines and the response to immunotherapy. This observation suggests that treatments capable of modulating microbial networks and promoting specific bacterial clades may modulate the host's immune response. Hence, beyond their expected effect in the targeted tissue, part of the therapeutic effect of drugs could rely on this mechanism. In psoriasis patients, observational studies suggest that gut microbiome is altered differently after the use of anti-IL17 or anti-IL23 biologic agents. Main objective: To determine the evolution of microbial composition of fecal samples issued to patients who responded to a biologic agent (IL-17 inhibitors, IL-23 inhibitors) and have stopped their treatment for 2 to 4 weeks before the index date, at baseline and 6 months or clinical relapse after treatment discontinuation Design of the study: Prospective french multicentre observational cohort study Population of study participants: Patients with psoriasis in remission after IL23i or IL17inhibitor treatments and who have stopped their medication for 2 to 4 weeks. Number of participants included: 50 adult patients considered in remission and have stopped for at least 2 weeks and a maximum of 4 weeks, one of the following biologic agent: secukinumab, ixekizumab, brodalumab, bimekizumab, guselkumab, tildrakizumab, or risankizumab

The purpose of this study is to evaluate the safety and efficacy of ABT-493/ABT-530 in adults with genotype 2 chronic hepatitis C virus (HCV) infection.

The purpose of this study is to assess the safety and efficacy of ABT-493/ABT-530 following 12 weeks of treatment in adults with chronic Hepatitis C Virus Infection genotype 1, 2, 4, 5 or 6 infection and compensated cirrhosis.

The primary objectives of the study are to evaluate the efficacy, safety, and tolerability of treatment with sofosbuvir/velpatasvir/voxilaprevir (Vosevi®; SOF/VEL/VOX) fixed-dose combination (FDC) for 12 weeks and of sofosbuvir/velpatasvir (Epclusa®; SOF/VEL) FDC for 12 weeks in direct-acting antiviral (DAA)-experienced adults with chronic hepatitis C virus (HCV) infection with or without cirrhosis who have not received prior treatment with a regimen containing an inhibitor of the HCV NS5A protein.

The study will evaluate the safety and therapeutic efficacy of the human monoclonal antibody (mAb) VRC-HIVMAB060-00-AB (VRC01), when administered during analytic treatment interruption (ATI), in adults who began antiretroviral therapy (ART) during early acute HIV infection.
