Active clinical trials for "Infections"

To examine the usefulness and safety of the antiviral drug foscarnet in treating AIDS patients with cytomegalovirus (CMV) infection that is causing sight-threatening inflammation of the retina in one or both eyes (CMV retinitis). Because of the seriousness of sight-threatening CMV retinitis in AIDS patients and a lack of other available treatments for those patients who cannot be treated with ganciclovir (DHPG) (because of its toxic effect on the body's blood-forming cells, because it did not control the disease, or because patient's blood cell or platelet counts are too low to begin with), it is worthwhile to try an immediate trial with foscarnet. AMENDED: ACTG 093 was originally designed as a randomized dose-ranging study of foscarnet maintenance therapy. Patients enrolled between March 17, 1989, and January 1, 1990, received either 60 mg/kg/day or 90/mg/kg day as maintenance therapy following the 2 week induction period. Based on the preliminary results of ACTG 015/915, which studied maintenance doses of foscarnet of 60 mg/kg/day, 90 mg/kg/day and 120 mg/kg/day, the 60-mg/kg/day and 90/mg/kg/day arms of this study have been closed. All patients entering the study beginning January 2, 1990 will receive foscarnet maintenance therapy on a 120/mg/kg/day algorithm following induction.

To examine the dose of zidovudine (AZT) that was used in the first placebo-controlled study of AZT in AIDS patients as well as a lower dose of AZT in order to determine if the lower dose results in less harmful side effects while still being effective. Previous studies have shown the effectiveness of AZT in AIDS therapy. AZT has been effective in test tube studies at varying doses. There is a need to see if lower doses result in effective therapy with less harmful side effects.

The purpose of this study is to see if giving azidothymidine (AZT) to HIV-positive patients with hemophilia is safe and if it is effective in lowering HIV levels and boosting the immune system. HIV infects and inactivates certain blood cells that are part of the body's immune system. The damage to the body's immune system can result in unusual infections and/or unusual forms of cancer. A large percentage of hemophiliacs are HIV-positive and there is a clear risk for the development of AIDS in these patients. AZT may be effective in lowering HIV levels and boosting the immune system but its side effects are not understood in these patients.

To evaluate the safety and tolerance of oral zidovudine (AZT) when given over a period of 24 weeks to children between 3 months and 12 years of age. The effectiveness of AZT in treating HIV infection in infants and children will also be evaluated. HIV infection in children is most often associated with symptomatic disease and poor prognosis. Treatment with antiviral therapy may be effective in altering the course of the disease and decreasing mortality in these children. AZT has been shown to be effective in certain adult patients with symptomatic HIV infection. It is therefore likely that infected children may also benefit from this treatment.

To explore the safety and usefulness of foscarnet, an antiviral agent, in the treatment of cytomegalovirus (CMV) retinitis. Untreated CMV retinitis is a rapidly progressive, blinding disease in AIDS patients. The manner in which foscarnet breaks down in the body and the effect of increasing periodic intravenous doses are also studied. Foscarnet is active in vitro (test tube) against herpes viruses, including CMV, by inhibiting the virus DNA polymerases, enzymes necessary for virus replication, without affecting cellular DNA polymerases. Opportunistic CMV disease in AIDS is usually seen as retinitis, colitis, esophagitis, hepatitis, pancreatitis, encephalitis, or pneumonia. Ganciclovir has been used to treat AIDS patients with CMV disease but can cause severe neutropenia (very low neutrophil cell counts). Foscarnet does not suppress the production of neutrophils or other leukocytes (myelosuppression) and has shown in vitro activity against HIV.

Summit is developing ridinilazole as a novel antimicrobial for Clostridioides difficile Infection (CDI), formerly known as Clostridium difficile Infection, with the goal of demonstrating an improved Sustained Clinical Response rate in subjects treated with ridinilazole as compared to subjects with vancomycin. A phase 2 proof of concept study, with vancomycin as comparator, demonstrated these attributes with a comparable safety profile. A high fecal concentration of ridinilazole and little systemic exposure were noted. The rationale for this phase 3 study is to confirm the improvement in sustained clinical response of CDI over vancomycin and to compare the safety and tolerability of ridinilazole to that of vancomycin.

Study aimed to evaluate the efficacy and tolerance of Lazolex®, an emollient gel, to treat mucocutaneous lesions caused by herpes simplex virus.

Phase 1b, randomized, open-label, study to evaluate the safety, tolerability, and immunogenicity of RVM-V001 only, RVM-V002 only, or RVM V001 + RVM V002 (Co administered as Separate Injections) in healthy adults. The study will be conducted at one site in Singapore.

The main objective of the study is to compare the effectiveness of moxifloxacin triple therapy with levofloxacin-based sequential therapy in terms of eradication rate, safety, and patient compliance.

This is a prospective clinical intervention trial where patients with moderately active ulcerative colitis are randomized to either normal healthy diet or a diet with elimination of emulsifying agents within the E 400-group with special respect to carragenan, CMC and polysorbates. At study start and end after one month their diet, clinical characteristics and microbiota will be analysed. The hypotheses are that their disease activity measured with calprotectin and their microbiota will improve after intervention.
