Filter by:This trial is a multi-center, open label, randomized controlled, non-inferiority phase III trial evaluating the safety and efficacy of a 3 g oral dose of zoliflodacin compared to a combination of a single intra-muscular 500 mg dose of ceftriaxone and a single 1 g oral dose of azithromycin for the treatment of uncomplicated gonorrhoea.
This study evaluates and compares two implementation strategies of an online HIV prevention intervention: Strategy 1 in which community-based organizations apply, and are selected, for funding to deliver Keep It Up! through current HIV testing programs; and Strategy 2 which is a "direct-to-consumer" model where centralized staff at Northwestern University recruit participants nationally through online advertising campaigns and manage engagement.
The aim of this research protocol is to test the efficacy of a self-care intervention through a randomized controlled trial (RCT), for increasing protective sexual health behaviors among youth in the participating Native American community. The investigators will randomize 450 youth and young adults ages 14-26 to the self-care intervention or a control program. Efficacy data will be collected up to 6 months post-intervention. The primary outcome will be uptake of sexually transmitted infection (STI) screening. Secondary outcomes will include: a) sexual risk and protective behaviors; and b) psychosocial assets and resources. The investigators hypothesize the self-care intervention will increase protective behaviors by: i) helping youth gain knowledge of their own sexual health risks, assets and resources; ii) motivating protection of those assets and resources; and iii) encouraging good health practices and making responsible choices.
The Centers for Disease Control and Prevention has identified antimicrobial-resistant (AMR) Neisseria gonorrhoeae (NG) as one of the nation's top three urgent AMR threats. Since the advent of antibiotics in the 1930s, NG has developed resistance to every first-line antibiotic. Parenteral third-generation cephalosporins are now the only class of drug with consistent efficacy against NG. New therapies are urgently needed. Although some novel antimicrobials are under development, reevaluating older drugs is another option for quickly identifying additional treatments for gonorrhea. We propose a demonstration study to test a single dose of aztreonam for the treatment of pharyngeal gonorrhea. We chose to focus on pharyngeal gonorrhea because these infections are common, play an important role in fostering gonococcal resistance, and are harder to eradicate than genital infections. Although aztreonam appears to be >98.6% efficacious for anogenital NG, its efficacy at the pharynx may be less. Only 8 cases of pharyngeal gonorrhea have been documented to be treated with aztreonam, but of those, only 5 (62.5%) were cured. The dose used in those studies was 1g of aztreonam. Most antibiotics have a lower efficacy at the pharynx than anogenital sites, which is likely due to drug pharmacokinetics, i.e. difficulty in penetrating pharyngeal tissue. Thus, in the proposed study, we plan to treat 50 subjects with untreated pharyngeal gonorrhea with 2g IM Aztreonam. Objectives: The proposed study aims to evaluate the efficacy of a single 2g intramuscular (IM) dose of aztreonam in the treatment of pharyngeal gonorrhea. Secondary objectives include documenting the efficacy stratified by minimal inhibitory concentration (MIC) compared with the previously document area under the curve (AUC) in order to estimate a pharmacodynamic criterion. We will also attempt to determine whether aztreonam monotherapy induces antimicrobial resistance among treatment failures. Lastly, we will evaluate the tolerability of 2g of IM aztreonam. The specific aims are: 1. Determine the proportion of persons whose pharyngeal gonococcal infections are cured with a single dose of 2g aztreonam intramuscularly. 2. Determine the proportion of persons with urethral and/or rectal gonorrhea whose infections are cured with a single dose of 2g aztreonam IM. 3. Evaluate the tolerability of 2g IM of aztreonam . 4. Estimate the best pharmacodynamics criterion (i.e. AUC/MIC ratio) for pharyngeal gonorrhea treated with aztreonam using previously published AUC for 2g aztreonam and NG isolate MIC. 5. Among treatment failures, conduct exploratory analyses comparing pre- and post-treatment MIC for evidence of induced resistance. Study Design: Prospective cohort Study Population & Inclusion Criteria: Persons diagnosed with pharyngeal gonorrhea or gonococcal urethritis who are undergoing pharyngeal gonorrhea testing, who are not yet treated. Intervention: 2g IM aztreonam x 1 Primary Outcome: Negative gonorrhea culture 4-7 days (+/- 1 day) after treatment Sample Size: 50 persons
This is a multi-center study with a minimum of three sites in the United States. The study will enroll approximately 1750 female subjects, 14 years of age and older, 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. and a Clinical Laboratory Improvement Amendments (CLIA) Waiver.
This is a Phase 1, interventional, non-randomized, experimental infection model study with healthy adult males adults (N=32) between the ages of 18-36 at study enrollment. The study is designed to test the requirements of predicted N. gonorrhoeae virulence determinants for gonococcal infection in the male urethra. The duration for all participants will be about 3 weeks. Study duration will be approximately about 18 months for implementation and enrollment. The primary objectives of the present study are to: (1) compare infectivity of different isogenic mutants with wild-type (WT) N. gonorrhoeae in noncompetitive infections and to (2) assess relative fitness of the mutant in competitive infections initiated by inocula containing equivalent numbers of both WT and mutant strains for mutants with WT infectivity.
This is a randomized controlled trial which will evaluate dual gonorrhea/chlamydia test uptake and other outcomes in men who have sex with men (MSM) in three trial arms - 1) a pay-it-forward testing arm, 2) a pay-what-you-want testing arm, and 3) standard of care arm.
This is a phase I, parallel, open-label, randomized, cross-over, single-center study with zoliflodacin administered as granules for oral suspension with or without food. It is planned to enroll 2 cohorts (Cohorts 1 and 2) of 24 subjects each (48 subjects in total), with the target of achieving data in 20 evaluable subjects per cohort. Single doses of zoliflodacin will be assessed within each cohort in a two period cross-over design. Each subject will receive one of the following regimens per period, depending on cohort, in a sequence according to the randomization schedule (per cohort, subjects will be randomized immediately before dosing in Period 1), separated by a minimum 4 day washout between each period. The actual length of washout period may change pending emerging PK data. Cohort 1: - Regimen A: 3 g zoliflodacin oral suspension; oral administration after an overnight fast - Regimen B: 3 g zoliflodacin oral suspension; oral administration with a standardized high calorie, high-fat breakfast Cohort 2 - Regimen C: 4 g zoliflodacin oral suspension; oral administration after an overnight fast - Regimen D: 4 g zoliflodacin oral suspension; oral administration with a standardized high calorie, high-fat breakfast
Sexually transmitted infections (STIs) are highly prevalent among adolescents. Despite established principles for STI control, clinical practices related to screening and diagnosis, treatment, and prevention of STIs among adolescents are suboptimal. There is an urgent need to expand our screening programs to nontraditional healthcare settings such as emergency departments (ED) to reach those adolescents who would otherwise not receive preventive healthcare, and to determine the most efficient and cost-effective method for providing this screening. The goal of this study is to leverage our recent insights obtained from single center ED-based adolescent gonorrhea and chlamydia screening research and apply them across a national pediatric ED research network to determine the most clinically effective and cost-effective screening approach for adolescents when implemented into a real-world clinical setting through a pragmatic trial. This will be accomplished through a network of children's hospital EDs with a track record of robust research collaboration (Pediatric Emergency Care Applied Research Network or PECARN). This intervention will rely on an innovative approach that electronically integrates patient-reported data to guide clinical decision support. The investigators will apply human factors modeling methods to perform ED workflow evaluations at each participating pediatric ED to determine the most efficient way to integrate the screening process into everyday clinical care. Following these analyses, the investigators will conduct a comparative effectiveness pragmatic trial of targeted STI screening (screening only those disclosing high risk sexual behavior) versus universally-offered STI screening (offered to all, regardless of risk) through electronic integration of patient reported data for provision of clinical decision support. The investigators will then develop decision analytic models to evaluate the cost-effectiveness of targeted screening compared to universally offered screening.
