Filter by:The purpose of this clinical trial is to learn about the safety and effects of the study medicine (called PF-07275315) in healthy participants. This study is seeking participants who: - Are healthy as determined by medical evaluation. - Are willing and able to comply with all scheduled visits, treatment plan, laboratory tests, lifestyle considerations, and other study procedures. - Have a body mass index (BMI) of 17.5 to 32 kilogram per meter square - a total body weight of more than 50 kilograms (110 pounds) Participants will be divided randomly into 8 different groups. All participants will receive either one PF-07275315 or a harmless treatment that has no medical effect (placebo) intravenous (IV) infusion (given directly into a vein). Participants will take part in this study for up to 541 days. During this time, eligible participants will receive single increasing amounts of PF-07275315 or placebo. Increase will only occur if the sponsor agrees that the next dose is likely to have acceptable safety and tolerability. The follow-up visit will take place 271 days after first treatment.
Phase II, non-randomized, open-label, comparative, single center national trial in Guinea, aimed to assess the humoral vaccine immune response induced by BBIBP-CorV vaccine in 200 adults aged between 18 and 45 years or 55 or older, one month after receiving the complete COVID-19 vaccination schedule.
This is a Phase 2a, randomized, double-blind, proof-of-concept, single-center study evaluating the safety, tolerability, and whole blood concentration of TP-05 (lotilaner) in the killing of ticks after they have attached to human skin.
This is a Phase 1, first-in-human (FIH), double-blinded, placebo-controlled study where healthy subjects are randomly allocated to receive APNmAb005 or placebo. Approximately 5 dosing groups (cohorts) are planned with 8 subjects (randomized to 6 active: 2 placebo) per cohort. the starting dose of APNmAb005 is 5 mg/kg and the anticipated doses for subsequent cohorts are 10, 25, 50 and 70 mg/kg. A Safety Review Team (SRT) will review data on an ongoing basis throughout the study and before progression to the next dose level cohort. Subjects will receive a single dose of either APNmAb005 or placebo administered as a single IV infusion on Day 1 of the study and will remain in the study center until Day 3 (48 hours after dosing). They will return to the study center for 7 outpatient visits. The duration of the study, excluding screening, is approximately 71 days.
The purpose of this trial is to determine the safety of ultraviolet light (UV-C) irradiation as a method to sanitize hands instead of chemical-based sanitizers. Eligible participants will be enrolled and receive treatment with the Violet UV-C device or UV-B. Punch biopsies will be performed following UV exposure to quantify any changes in cellular and molecular properties of the tissue.
A first-in-human study to evaluate the safety, tolerability, and pharmacokinetics of single ascending doses and multiple ascending doses of EDI048 administered orally in healthy volunteers.
The purpose of this study is to characterize the effect of rifampin (Part A) and itraconazole(Part B) on the single-dose pharmacokinetics (PK) of Larotinib in healthy adult participants.
In response to the COVID-19 pandemic, several vaccines (Pfizer, Moderna, Astrazeneca, Janssen) have been developed and are being administered to millions of people in France and billions around the world through massive vaccination programs. The Janssen vaccine is the fourth COVID-19 vaccine to be licensed in Europe. It received a European marketing authorization for all adults, without age limit, on March 11, 2021. Janssen's vaccine is a viral non replicating vector (adenovirus) vaccine targeting the Spike protein of the SARS-CoV-2 virus. It differs from currently available vaccines in that it is a single-dose regimen with significant protection at 28 days post-injection. Monitoring of the durability of the immune response is essential to assess the need for a booster vaccination. Insufficient data are available in the adult population regarding the evolution of the immune response. This point seems to be even more important in the elderly. Indeed, their immune system declines with age, leading to a greater susceptibility to infectious diseases and a weaker response to vaccination. This is called immunosenescence. Vaccination in this population is essential to avoid severe COVID-19 cases, since older people are particularly at risk. Two CoviCompare studies with two licensed vaccines messenger RNA vaccines (Pfizer, Moderna) are underway to evaluate the immune response to each vaccine according to age. We propose to conduct a study to evaluate the immunogenicity of the Janssen vaccine in different age groups with long-term follow-up. This will allow determining the need of a booster. A common battery of in vitro and ex vivo immuno-monitoring tests has been set up to systematically assess the acquisition of humoral and cellular immunity over time over a period of 24 months following vaccination in the CoviCompare project. This trial, part of the CoviCompare project will use the same immunomonitoring set. This will also allow comparison of the immune response to different vaccines in subjects of different age in order to determine in this at risk population the better vaccination schedules. The only difference between this trial and the other 2 trials of the CoviCompare project is that adults aged 18-45 will not be concerned here, because the adenovirus vaccine is not recommended for this age group in France
The purpose of the MEQ00073 study is to assess the immunogenicity and safety of a booster dose in children who had been vaccinated with MenACYW conjugate vaccine approximately 5 years earlier as toddlers as part of the MET51 study, and to describe the persistence of a priming dose in children and adolescents who had been vaccinated with MenACYW conjugate vaccine approximately 5 years or 10 years earlier as toddlers as part of the MET51 study, the immunogenicity and safety of a booster dose in adolescents who had been primed with MenACYW conjugate vaccine as toddlers as part of the MET51 study, and the immunogenicity and safety of a second booster dose in adolescents approximately 5 years after a first booster dose as children approximately 5 years after the priming dose as toddlers.
