This is a randomized, double-blind, placebo-controlled Phase Ib/IIa study to evaluate the safety, tolerability, efficacy, pharmacokinetics, and immunogenicity of XW001 inhalation in children with RSV infection in China

The overall objective is to compare the effect of Vancomycin and Tobramycin powder combined (treatment) to Vancomycin powder (control) in the reduction of post-fixation infections of tibial plateau and tibial pilon fractures at high risk of infection (collectively considered the "study injuries").

This study will assess the efficacy of an integrated outpatient treatment model for persons with opioid use disorder and injection related infections. The investigators hypothesize that outpatient antibiotic treatment coupled with comprehensive treatment for opioid use disorder will demonstrate a safe and effective way to manage patients. Results could improve the current protocols for the treatment of individuals with opioid use disorder and severe infections.

Background: Bismuth quadruple therapy is currently the recommended first-line regimen for Helicobacter pylori (H. pylori) infection in regions with high clarithromycin resistance. Recent randomized trials showed that 7-day vonoprazan-based triple therapy is superior to 7-day lansoprazole-based triple therapy in Japanese. A recent trial further showed that 7-day vonoprazan-based high dose amoxicillin dual therapy was non-inferior to 7-day vonoprazan-based triple therapy in Japanese. However, whether vonoprazan based dual, triple, and quadruple therapies are superior or non-inferior to lansoprazole based triple or quadruple therapy remains unknown. Objective: The investigators aimed to compare the efficacy and safety of 14-day vonoprazan-based dual therapy, triple therapy, bismuth quadruple therapy, reverse hybrid therapy, and lansoprazole-based bismuth quadruple therapy and triple therapy in the first-line treatment of H. pylori infection in this pilot study. Methods: Using a block randomization with a block size of 16 in a 1:1 ratio, 1200 eligible adult subjects aged 20 years or greater with at least two positive tests for H. pylori infection will be randomized to receive one of the following regimens: (A) vonoprazan-based triple therapy for 14 days (T-V14): vonoprazan 20mg twice daily, clarithromycin-XL 500mg twice daily, amoxicillin 1000mg twice daily for 14 days ; or (B) vonoprazan-based triple therapy for 7 days (T-V7): vonoprazan 20mg twice daily, clarithromycin-XL 500mg twice daily, amoxicillin 1000mg twice daily for 7 days ; or (C): vonoprazan-based dual therapy for 14 days (D-V14): vonoprazan 20mg twice daily, amoxicillin 750mg every 8 hour for 14 days; (D): vonoprazan-based high dose dual therapy for 14 days (HD-V14): vonoprazan 20mg twice daily, amoxicillin 750mg four times a day for 14 days; or (E) vonoprazan-based bismuth quadruple therapy for 14 days (BQ-V14) vonoprazan 20mg twice daily, bismuth tripotassium dicitrate 300 mg three times a day, tetracycline 500mg three times a day, and metronidazole 500mg three times a day for 14 days; or (F) vonoprazan-based reverse hybrid therapy for 14 days (RH-V14): vonoprazan 20mg twice daily, and amoxicillin 1000mg twice daily for 14 days, plus clarithromycin-XL 500mg twice daily and metronidazole 500mg twice daily for the first 7 days ; or (G) lansoprazole-based bismuth quadruple therapy for 14 days (BQ-L14) lansoprazole 30mg twice daily, bismuth tripotassium dicitrate 300 mg three times a day, tetracycline 500mg three times a day, and metronidazole 500mg three times a day for 14 days; or (H) lansoprazole-based triple therapy for 14 days (T-L14): lansoprazole 30mg twice daily, clarithromycin-XL 500mg twice daily, amoxicillin 1000mg twice daily for 14 days. Subjects who fail after first-line therapy will be randomized to receive either vonoprazan-based levofloxacin triple therapy (LT-V14) containing vonoprazan 20mg twice daily, levofloxacin 250mg twice daily, and amoxicillin 1000mg twice daily for 14 days or vonoprazan-based levofloxacin reverse hybrid therapy (LRH-V14) containing vonoprazan 20mg twice daily, and amoxicillin 1000mg twice daily for 14 days, plus levofloxacin 250mg twice daily and metronidazole 500mg twice daily for the first 7 days. The minimum inhibitory concentrations will be determined by agar dilution test. 23S ribosomal RNA and gyrase A mutations will be determined by PCR methods followed by direct sequencing in a subgroup of patients. The TWB2.0 SNP array will be used for genotyping of genome wide single nucleotide polymorphism. Outcome analysis: The primary outcome is the eradication rate in the first-line treatment. The secondary outcomes are the compliance, frequency of adverse events, the overall eradication rate after two treatments.

This phase I trial investigates the side effects of cabozantinib and nivolumab in treating patients with cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced) and who are undergoing treatment for human immunodeficiency virus (HIV). Cabozantinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving cabozantinib and nivolumab may shrink or stabilize cancer in patients undergoing treatment for HIV.

This study will investigate the effects of cranberry and quillaja capsules on symptoms of uncomplicated urinary tract infections.

BK virus infection is one of the causes of renal allograft loss in the current era. Reduction of immunsuppression is the only intervention that prooved to be effective in treating of BK virus in kidney transplant recipient. However, there are evidences from retrospective and prospective studies showed that leflunomide and mTOR inhibitor such as everolimus or sirolimus have positive outcomes in treatment of BK virus in kidney tranplant recipient. The investigators conduct the RCT to compare the efficacy of leflunomide and mTOR inhibitor everolimus, in treatment of BK virus infected patients who do not respond to immunosuppression reduction.

Urological pathogens are effected by rising antimicrobial resistance rates due to the frequent use of antimicrobials for treatment and prophylaxis. Intravesical instillation with hyaluronic acid (HA) and chondroitin sulphate (CS) obtained positive outcomes in the treatment of overactive bladder, radiation cystitis and interstitial cystitis by replenishment of the glycosaminoglycan layer of the bladder. This study is to investigate whether intravesical instillation with HA-CS in patients with recurrent urinary tract infections (rUTI) is superior to a placebo instillation in terms of reduction of rate of symptomatic urinary tract infections (UTIs) (based on clinical diagnosis) needing treatment with antimicrobials within 12 months after randomisation.

RIO is a placebo-controlled double-blinded two arm prospective phase II randomised controlled trial . This study will test the use of broadly neutralising antibodies (bNAbs) in participants with treated primary HIV infection (PHI).

The gut microbiota is critical to health and functions with a level of complexity comparable to that of an organ system. Dysbiosis, or alterations of this gut microbiota ecology, have been implicated in a number of disease states. Fecal microbiota transplantation (FMT), defined as infusion of feces from healthy donors to affected subjects, is a method to restore a balanced gut microbiota and has attracted great interest in recent years due to its efficacy and ease of use. FMT is now recommended as the most effective therapy for CDI not responding to standard therapies. Recent studies have suggested that dysbiosis is associated with a variety of disorders, and that FMT could be a useful treatment. Randomized controlled trial has been conducted in a number of disorders and shown positive results, including alcoholic hepatitis, Crohn's disease (CD), ulcerative colitis (UC), pouchitis, irritable bowel syndrome (IBS), hepatic encephalopathy and metabolic syndrome. Case series/reports and pilot studies has shown positive results in other disorders including Celiac disease, functional dyspepsia, constipation, metabolic syndrome such as diabetes mellitus, multidrug-resistant, hepatic encephalopathy, multiple sclerosis, pseudo-obstruction, carbapenem-resistant Enterobacteriaceae (CRE) or Vancomycin-resistant Enterococci (VRE) infection, radiation-induced toxicity, multiple organ dysfunction, dysbiotic bowel syndrome, MRSA enteritis, Pseudomembranous enteritis, idiopathic thrombocytopenic purpura (ITP), and atopy. Despite FMT appears to be relatively safe and efficacious in treating a wide range of disease, its safety and efficacy in a usual clinical setting is unknown. More data is required to confirm safety and efficacy of FMT. Therefore, the investigators aim to conduct a pilot study to investigate the efficacy and safety of FMT in a variety of dysbiosis-associated disorder.
