Active clinical trials for "Chlamydia Infections"

The purpose of this study is to evaluate the effect of utilizing a rapid turnaround CT/NG test on treatment of female patients in the emergency department or urgent care setting with possible STIs.

Evaluate the clinical efficacy and safety of WC2031 200 mg tablets taken orally once a day for 7 days versus Vibramycin (doxycycline) 100 mg capsules taken orally twice a day for 7 days, for the treatment of uncomplicated urogenital Chlamydia trachomatis infection. Primary efficacy endpoint is microbiological cure at Day 28. Safety assessments are adverse events, changes in vital signs and laboratory test results.

The WHO has initiated a program to eliminate trachoma, blinding eye infection caused by Chlamydia trachomatis, in large part by mass distributions of oral azithromycin. The proposed study will determine the frequency and treatment target of community-wide mass antibiotic treatment. We will also study the impact of mass antibiotic distribution on antibiotic-resistance in pneumococcus.

This study will test the safety and effectiveness of an investigational antibiotic drug, rifalazil for the treatment of uncomplicated genital Chlamydia trachomatis infection. This study will examine the effects of 25 milligram of rifalazil compared with azithromycin 1 gram, which will be given as a single dose to women who have genital chlamydial infection.

Mass antimicrobial administrations have been remarkably successful in reducing the prevalence of the ocular strains of Chlamydia that cause trachoma. Repeated distributions progressively lower the prevalence of infection, and in some cases may even result in local elimination. Mass treatments cannot be continued forever, due to concerns about cost and antibiotic resistance. The hope has been that other measures such as latrine construction and hygiene programs would prevent infection from returning. Unfortunately, no non-antibiotic measure has yet demonstrated an effect on infection. We hypothesize that Chlamydial infection will return to communities when treatment ends. We hypothesize that infection will be completely eliminated in all communities treated for seven years. We hypothesize that identifying and treating clinically active cases among preschool aged children will delay or even prevent reemergence at a far lower cost than mass treatment of all individuals.

Chlamydia is a common infection among youth and can be given from one person to another during sex. Many people who have chlamydia have no signs of infection at all, but can pass the infection to anyone they have sex with. If not treated, chlamydia can lead to serious health problems. This study will look at how well medicines given for chlamydia infection work. The study requires 306 evaluable subjects, chlamydia-positive, males and non-pregnant females, ages 12-21, living in long-term, gender-segregated youth correctional facilities. Participants will be assigned to receive either doxycycline (2 times per day, by mouth, for 7 days) or azithromycin (1 single dose by mouth). Study procedures will include collection of at least 3 urine samples to test for chlamydia. Study visits will occur during initial enrollment in the study, day 28 after starting treatment, and day 67. Participants will be involved in study related procedures for up to 67 days.

A clinical trial to compare the efficacy of azithromycin (Arm 1) vs. doxycycline (Arm 2) administered per CDC's STD Treatment Guidelines for rectal Chlamydia trachomatis (CT) in men who have sex with men (MSM). Subjects will be males aged = / > 18 years with a microbiologically confirmed diagnosis of rectal CT and at least one male sex partner in the past 12 months. The trial will be conducted at two sites in the US and will enroll up to 274 total subjects to achieve 246 subjects who contribute to the primary analysis. The duration of this study will be approximately 16 months 22 months with subject participation duration 29 days. The primary objective of this study is to compare the efficacy of azithromycin vs. doxycycline for treatment of rectal CT infection in MSM based on microbiologic cure (negative NAAT) at Day 29.

The proposed study is a single center (with multiple long-term YCFs) treatment trial of the CDC-recommended azithromycin regimen (1 gm PO once) for chlamydia in males. This study is designed primarily to determine the frequency of chlamydia treatment failure following azithromycin in males who do versus do not have urethral symptoms of urethral discharge and/or dysuria. Anticipated enrollment is 446 males, between the age of 12 to 21 years old, with subject participation duration of 28 days and study duration of 4 years. The primary objective of the study is to assess the microbiological efficacy of azithromycin in uncomplicated Chlamydia trachomatis infection in males with versus without urethral symptoms in YCFs.

PREGNANT WOMEN IN ANTENATAL CLINIC WILL BE SCREENED FOR CHLAMYDIA TRACHOMATIS INFECTION WITH ENDOCERVICAL SWAB.THOSE THAT TEST POSITIVE AND SATISFY THE INCLUSION CRITERIA WILL BE COUNSELLED AND ENROLLED INTO THE STUDY AFTER OBTAINING INFORMED CONSENT.THE PARTICIPANTS WILL BE RANDOMISED INTO ONE OF THE TWO GROUPS.THE DRUGS WILL BE TAKEN FOR I WEEK AND THE SEXUAL PARTNER(S) WILL ALSO BE TREATED WITH DOXYCYCLINE FOR 1 WEEK. BARRIER CONTRACEPTION WILL ALSO BE USED DURING THE TREATMENT.THE SEXUAL PARTNERS WILL BE CONTACTED THROUGH TELEPHONE CALLS AND THE BENEFITS OF PARTICIPATING IN THE STUDY WILL BE EXPLAINED TO THEM. LATEX MALE CONDOM WILL BE GIVEN TO THE WOMEN. ALSO, FOLLOW-UP TELEPHONE CALLS WILL BE PUT ACROSS TO THEM DURING THE TREATMENT WEEK TO ENHANCE COMPLIANCE. A REPEAT ENDOCERVICAL SWAB WILL BE TAKEN 4 WEEKS AFTER TREATMENT TO CHECK FOR MICROBIOLOGICAL CLEARANCE. A STUDY PROFORMA WILL BE FILLED DURING THIS VISIT. THE DATA WILL BE ANALYSED USING STATISTICAL PACKAGE FOR SOCIAL SCIENCES VERSION 17.

Trachoma is a disease of poverty, which in the hyperendemic areas affects all individuals by the time they are two years old. Active disease is concentrated in children and occurs sporadically in adults. Infection is more widespread. It is anticipated that 25% of the children will be blinded by this disease if they live to be 60 years of age. The blindness rates are higher in women, presumably because of their closer contact with children who can infect them and add to damage from infections the women had while young. This proposal is to better define how azithromycin in community-based treatment can be used to eliminate blinding trachoma. We will also take the opportunity to join these field studies with genetic epidemiologic studies to better understand the dynamic epidemiology of Chlamydia trachomatis infection in a trachoma endemic area. The empiric data generated from the treatment/follow-up studies, together with the information on sources and spread patterns from genetic epidemiology will be used to generate more robust models to guide future treatment/re-treatment protocols. We propose to conduct a randomized, community based trial in the Maradi region of Niger to test the hypothesis that two community wide azithromycin treatments, spaced one month apart, are significantly more effective in reducing ocular C. trachomatis infection and trachoma at one year compared to a single mass azithromycin treatment.
