Phase II trial evaluating the clinical efficacy of cefixime for treatment of active syphilis in non-pregnant women in Brazil (CeBra).

BACKGROUND: Syphilis is a sexually and vertically transmitted infection caused by the bacteria Treponema pallidum for which there are few proven alternatives to penicillin for treatment. For pregnant women infected with syphilis, penicillin is the only WHO-recommended treatment that will treat the mother and cross the placenta to treat the unborn infant and prevent congenital syphilis. Recent shortages, national level stockouts as well as other barriers to penicillin use call for the urgent identification of alternative therapies to treat pregnant women infected with syphilis. METHODS: This prospective, randomized, non-comparative trial will enroll non-pregnant women aged 18 years and older with active syphilis, defined as a positive rapid treponemal and a positive non-treponemal RPR test with titer ≥1:16. Women will be a, domized in a 2:1 ratio to receive the oral third generation cephalosporin cefixime at a dose of 400 mg two times per day for 10 days (n = 140) or benzathine penicillin G 2.4 million units intramuscularly based on the stage of syphilis infection (n = 70). RPR titers will be collected at enrolment, and at three, six, and nine months following treatment. Participants experiencing a 4-fold (2 titer) decline by 6 months will be considered as having an adequate or curative treatment response. DISCUSSION: Demonstration of efficacy of cefixime in the treatment of active syphilis in this Phase 2 trial among non-pregnant women will inform a proposed randomized controlled trial to evaluate cefixime as an alternative treatment for pregnant women with active syphilis to evaluate prevention of congenital syphilis.

Odon device for instrumental vaginal deliveries: results of a medical device pilot clinical study.

BACKGROUND: A prolonged and complicated second stage of labour is associated with serious perinatal complications. The Odon device is an innovation intended to perform instrumental vaginal delivery presently under development. We present an evaluation of the feasibility and safety of delivery with early prototypes of this device from an early terminated clinical study. METHODS: Hospital-based, multi-phased, open-label, pilot clinical study with no control group in tertiary hospitals in Argentina and South Africa. Multiparous and nulliparous women, with uncomplicated singleton pregnancies, were enrolled during the third trimester of pregnancy. Delivery with Odon device was attempted under non-emergency conditions during the second stage of labour. The feasibility outcome was delivery with the Odon device defined as successful expulsion of the fetal head after one-time application of the device. RESULTS: Of the 49 women enrolled, the Odon device was inserted successfully in 46 (93%), and successful Odon device delivery as defined above was achieved in 35 (71%) women. Vaginal, first and second degree perineal tears occurred in 29 (59%) women. Four women had cervical tears. No third or fourth degree perineal tears were observed. All neonates were born alive and vigorous. No adverse maternal or infant outcomes were observed at 6-weeks follow-up for all dyads, and at 1 year for the first 30 dyads. CONCLUSIONS: Delivery using the Odon device is feasible. Observed genital tears could be due to the device or the process of delivery and assessment bias. Evaluating the effectiveness and safety of the further developed prototype of the BD Odon Device™ will require a randomized-controlled trial.

Feasibility and safety study of a new device (Odón device) for assisted vaginal deliveries: study protocol.

BACKGROUND: Intrapartum complications are responsible for approximately half of all maternal deaths, and two million stillbirth and neonatal deaths per year. Prolonged second stage of labour is associated with potentially fatal maternal complications such as haemorrhage and infection and it is a major cause of stillbirth and newborn morbidity and mortality. Currently, the three main options for managing prolonged second stage of labour are forceps, vacuum extractor and caesarean section. All three clinical practices require relatively expensive equipment (e.g., a surgical theatre for caesarean section) and/or highly trained staff which are often not available in low resource settings. The specific aim of the proposed study is to test the safety and feasibility of a new device (Odón device) to effectively deliver the fetus during prolonged second stage of labour. The Odón device is a low-cost technological innovation to facilitate operative vaginal delivery and designed to minimize trauma to the mother and baby. These features combined make it a potentially revolutionary development in obstetrics, particularly for improving intrapartum care and reducing maternal and perinatal morbidity and mortality in low resource settings. METHODS/DESIGN: This will be a hospital-based, multicenter prospective phase 1 cohort study with no control group. Delivery with the Odón device will be attempted under normal labour and non-emergency conditions on all the women enrolled in the study. One-hundred and thirty pregnant women will be recruited in tertiary care facilities in Argentina. Safety will be assessed by examining maternal and infant outcomes until discharge. Feasibility will be evaluated by observing successful expulsion of the fetal head after one-time application of the device under standardized conditions (full cervical dilation, anterior presentation, +2 station, normal fetal heart rate).
