Filter by:This is a Phase 2 mechanistic clinical trial to assess the systemic and mucosal immunogenicity of the multicomponent meningococcal serogroup B vaccine (4CMenB or Bexsero (R)) (group 1, 40 subjects) against Neisseria gonorrhoeae, using a placebo vaccine (normal saline) as a comparator (group 2, 10 subjects). There will be approximately 50 participants, ages 18-49, both male and non-pregnant female subjects, enrolled at 1 site in the US. The goal will be to ensure adequate representation of subjects by sex in both treatment groups. The enrollment will be stratified by both sex and treatment arm. During enrollment of the "biopsy cohort" male and non-pregnant female subjects will be randomized 4:1 to either 4CMenB or placebo, up to a maximum of 10 male and 10 non-pregnant female subjects. Group 1 (approximate N=40) will receive two doses of 4CMenB on Day 1 and Day 29. Group 2 (approximate N=10) will receive two placebo injections on Day 1 and Day 29. Both groups will receive a single-dose prefilled syringe that is administered intramuscularly (0.5-mililiter each). The duration of each subject's participation is approximately 8 months, from recruitment through the last study visit, and the length of the study is estimated for 14 months. The primary objective is to characterize the rectal mucosal Immunoglobulin G IgG antibody response to Neisseria gonorrhoeae (GC) elicited by the 4CMenB vaccine as compared with the placebo vaccine (normal saline) in healthy adult subjects.
This is a multi-center study with a minimum of three sites in the United States. The study will enroll approximately 1750 female subjects and will have a study duration of approximately 9 months after enrollment of the first subject. Female subjects seen at the participating sites for any reason will be evaluated for enrollment in this study. All subjects will be managed per standard of care as applicable. Subjects who are enrolled in the study will perform self-collection of a vaginal swab to be tested by Click device, and allow the health care provider (HCP) to collect three additional vaginal swabs to be tested by recognized FDA-cleared comparator methods. Subjects will complete the study in a single visit. The primary objective is to assess the performance of the Click device for detection of Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), and Trichomonas vaginalis (TV) in self-collected vaginal specimens as compared to Patient Infected Status (PIS) determined by three approved comparator assays using vaginal specimens collected by a qualified HCP in support of obtaining FDA clearance.
The trial is to evaluate the pharmacokinetics and safety profiles of the single-dose of zoliflodacin in eight healthy male or female subjects ages 18 to 45 years inclusive. All subjects will be dosed in the morning of Day 1 in a staggered fashion with a minimum of several minutes apart. Each subject will receive a single 4g dose of zoliflodacin (2 x 2 g sachets of zoliflodacin) after at least an 8-h fast, which will continue for at least 4 h after dosing. Consumption of water will be permitted during the fasting period. Subjects will be monitored as inpatients in the Clinical Trial Unit (CTU) up to Day 4 and at the Final Visit (Day 8 ± 2). Study duration is approximately 4 weeks with subject participation duration up to 10 days (from dosing to final visit). The primary objective of this study is to evaluate the plasma PK of zoliflodacin after administration of a single 4-g oral dose under fasting conditions.
This is a PK study of a multi-dose oral cefixime regimen (three 800 mg doses given on a q 8-hour schedule) alone and also co administered with a single 1000 mg oral dose of azithromycin, both within a 24-hour period, in order to achieve total serum cefixime levels of mcg/mL for at least 20 hours. This will determine the tolerability of the regimen and whether there are significant changes in cefixime PK after co-administration. The primary pharmacokinetic objectives are: to determine if a cefixime dosing regimen of three 800 mg doses given alone, on a q 8-hour schedule achieves a total serum cefixime level that exceeds 2.0 mcg/mL for at least 20 hours; to determine if a cefixime dosing regimen of three 800 mg doses given on a q 8 hour schedule co-administered with a single 1000 mg of azithromycin, achieves a total serum cefixime level that exceeds 2.0 mcg/mL for at least 20 hours; and to evaluate whether a single 1000 mg dose of azithromycin alters the PK of a three dose regimen of 800
The purpose of this study is to develop a laboratory-based assay that will be a real-time PCR test to detect the organism N. gonorrhoeae and its most important genetic markers of antimicrobial resistance. This study will also determine factors associated with gonorrhoea and describe sexual behaviours of men who have sex with men, to inform parameters for a mathematical model of gonorrhoea transmission and antimicrobial resistant gonorrhoea.
This is an open-label Phase I study of plasma, genitourinary, rectal, and pharyngeal pharmacokinetics of a single 1000mg oral dose of solithromycin. Study Objectives: The primary objective is to determine the pharmacokinetics of solithromycin in plasma, vaginal, cervical, seminal, rectal, and pharyngeal fluid samples after a single 1000mg oral dose.
This is a multi-center Phase 2 randomized, open-label study in approximately 180 adult male and female subjects, between the ages of 18 and 55, who are in good health and meet all eligibility criteria. The study is designed to assess the safety and efficacy of an antimicrobial investigational product, AZD0914 manufactured by AstraZeneca, administered to adults to treat uncomplicated urogenital gonorrhea compared to treatment with ceftriaxone. Subjects will be randomly assigned 70:70:40 to receive a single, oral dose of 2000 mg of AZD0914, 3000 mg of AZD0914, or intramuscular dose of 500 mg of ceftriaxone. The drug name is also known as ETX0914.
This study is a Phase I, open label, non-randomized, dose-frequency escalation pharmacokinetics study among 24 healthy male and female subjects, aged 18 to 45 years to determine the pharmacokinetics and safety of high-, multi-dose cefixime for the treatment of reduced susceptibility gonorrhea. Stage 1(Cohorts A and B) will examine the pharmacokinetics of single 400mg and 800mg dose of cefixime. Stage 2(Cohorts C and D) subjects will take 800mg of cefixime every 12 hours for 2 doses. If that dosing regimen is well tolerated, the dose-frequency will escalate to 800mg every 8 hours for 3 doses, and serum levels of cefixime will be measured. Study duration is approximately 47 weeks.
The purpose of this study is to learn how to better treat gonorrhea infections. Gonorrhea is a sexually transmitted disease (STD) that is usually cured with a single antibiotic. However, some gonorrhea is not cured with a single antibiotic. The study will look at how well treating gonorrhea with 2 antibiotics works. Participants will be assigned to 1 of 2 treatment groups each receiving a combination of 2 antibiotics. Sites in the United States will recruit 500 male and female participants. Participants must be 15 to 60 years old, in good health and identified in participating sexually transmitted disease clinics as having uncomplicated cervical or urethral gonorrhea. Procedures include collection of current symptoms, medical and sexual history, sexual orientation, vital signs, height, weight, cervical/urethral cultures and clinical examinations. Volunteers will be involved for about 17 days.
