Filter by:This is an open-label, adaptive study using the P. falciparum induced blood stage malaria (IBSM) model to characterise the pharmacokinetic/pharmacodynamic (PK/PD) profile and safety of MMV367 (the IMP). Up to 18 participants will be enrolled in cohorts of up to 6 participants each. The study will proceed as follows for all participants: - Screening period of up to 28 days to recruit healthy adult participants. - Day 0: Intravenous inoculation with approximately 2,800 viable P. falciparum-infected red blood cells. - Days 1-3: Daily follow up via phone call or text message. - Days 4-7: Daily site visits for clinical evaluation and blood sampling to monitor malaria parasite numbers via quantitative polymerase chain reaction (qPCR). - Day 7 PM: Start of confinement within the clinical trial unit. - Day 8: Administration of a single oral dose of the IMP (MMV367). Different doses of MMV367 will be administered across and within cohorts in order to effectively characterise the PK/PD relationship. - Days 8-11: Regular clinical evaluation and blood sampling while confined to monitor malaria parasite numbers and measure MMV367 plasma concentration. - Day 11 AM: End of confinement within clinical trial unit. - Days 12-23: Outpatient follow-up for clinical evaluation and blood sampling. - Day 24: Initiation of compulsory definitive antimalarial treatment with Riamet® (artemether/lumefantrine) and/or other registered antimalarials if required. Treatment will be initiated earlier than Day 24 in the event of: - Insufficient parasite clearance following IMP dosing - Parasite regrowth following IMP dosing Characterising the pharmacokinetic/pharmacodynamic relationship of MMV367 - Participant discontinuation/withdrawal, - Investigator's discretion in the interest of participant safety. - Day 27: End of study visit for final clinical evaluation and to ensure complete clearance of malaria parasites.
This study will find the maximum safe dose (MSD) or maximum tolerated dose (MTD) of CYNK-001 which are NK cells derived from human placental CD34+ cells and culture-expanded. CYNK-001 cells will be given after lymphodepleting chemotherapy for the systemic cohort (IV) (intravenous). The intratumoral cohort (IT) will not be giving lymphodepletion. The safety of this treatment will be evaluated, and researchers want to learn if NK cells will help in treating recurrent glioblastoma multiforme.
Hospital infections comprise about half of all undesirable complications related to hospital treatment. In case of bacterial infection administration of antimicrobial agent is a therapy of choice. For maximum effectiveness, antimicrobial agents should be administered quickly in optimal doses. Moreover, the therapeutic concentration of properly selected drugs should be achieved as soon as possible. The relation between delays in the administration of antibiotics and increased mortality is well known. That is why proper empiric therapy is so important. Before antimicrobial investigation is completed, which may last up to 72 hours, a wide-spectrum antimicrobial should be administered according to the type of infection, its origin, and the characteristics of the local pathogens. The objective of this study is to compare the initial choice of empiric antimicrobial therapy and the results of both microbiological identification and susceptibility/resistance analysis of isolated pathogens. This project was designed as a prospective cohort study. Analysis was performed in a large multidisciplinary academic hospital and trauma center. All decisions on empiric therapy with antimicrobial used in infections caused by multidrug-resistant pathogens, that are made in different hospital wards except intensive care, are required by hospital procedures to be confirmed by intensivists. In our analysis, the initial choice of empiric therapy in the hospital wards other than the critical care unit was compared with the results of microbiological investigations and susceptibility/resistance analyses of isolated pathogens. Accurate microbial identification was performed with a VITEK® 2 automatic testing system. The microbroth dilution method with VITEK® 2 AST cards was used for the antibiotic susceptibility testing of isolated pathogens. Microbiological analyses were performed between 2018 and 2020 according to the regulations of the European Committee on Antimicrobial Susceptibility (EUCAST, version 9.0, 2019) and the National Reference Centre for Susceptibility Testing (NRCST, Warsaw, Poland).
This study is a Phase 1 / 2 trial to determine the safety and efficacy of CYNK-001, an immunotherapy containing Natural Killer (NK) cells derived from human placental CD34+ cells and culture-expanded, in patients with moderate COVID-19 disease.
This study will find the maximum tolerated dose or the maximum planned dose of CYNK-001 which contains natural killer (NK) cells derived from human placental CD34+ cells and culture-expanded. CYNK-001 cells will be given after lymphodepleting chemotherapy. The safety of this treatment will be evaluated, and researchers want to learn if NK cells will help in treating acute myeloid leukemia.
The objective of this proposal is to advance medication development for alcohol use disorder by examining the efficacy and mechanisms of action of minocycline, a neuroimmune modulator, as a potential treatment. This study has important clinical implications, as the available treatments for alcohol use disorder are only modestly effective and testing novel medications is a high research priority.
Optimal prescribing of antimicrobials is becoming increasingly challenging because of the growing complexity of guidelines and constantly changing distribution of infectious pathogens. Prescribing antimicrobials appropriately according to local guidelines optimizes therapy for the individual patient and reduces the emergence of resistance. By adapting and evaluating a smartphone based app containing local guidelines we aim to study appropriate prescribing of antimicrobials by physicians in three hospitals (Netherlands, Sweden and Switzerland).
This multi-center Phase I study is designed to characterize the safety, PK, and PD of TFV/LNG IVR to assess systemic and genital tract bioavailability in healthy women. The IVRs to be used in the study are TFV/LNG IVR (8-10mg per day/20μg per day) or placebo IVR. Samples will be obtained before, during and after 90 days of continuous or interrupted IVR use.
Background: - Vaccines and antiviral therapies help prevent and treat diseases. Researchers need a group of healthy volunteers for clinical trials. Clinical trials are studies that test these vaccines and therapies in people. Objective: - To screen volunteers for clinical trials for investigational or licensed vaccines or drugs to treat or prevent virus infections. Eligibility: - Healthy adults age 18 or older. Design: - Participants will be asked questions about their health history, including sexual activity and drug use. They will give blood samples. They may have a physical exam. They may give a urine sample. - Participants may have the inside of their nose either swabbed or washed with some fluid. The fluid will be collected. They may give a stool sample. - Participants may have an electrocardiogram. Soft, sticky patches will be attached to participants chest, arms, and legs. They will lie still on a table while the patches detect the heart s electrical signals. A machine will record these signals. - Participants may have lung function tests. These tests measure the volume of air moving in and out of the lungs. Participants will forcibly blow air into a machine. - Participants will be told if any tests show a medical problem. - If a participant is eligible and decides to join an investigational clinical trial, researchers will explain the study and the risks involved. Participants will sign a separate consent for that clinical trial.
The purpose of this study is to evaluate the effectiveness of bacteria called Lactobacillus GG, a Probiotic, in preventing the growth of resistant bacteria in the digestive tract in patients on broad spectrum antimicrobials.
