Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Maternal and neonatal infections are among the most frequent causes of maternal and neonatal deaths, and current antibiotic strategies have not been effective in preventing many of these deaths. Recently, a randomized clinical trial conducted in a single site in The Gambia showed that treatment with oral dose of 2 g azithromycin vs. placebo for all women in labor reduced selected maternal and neonatal infections. However, it is unknown if this therapy reduces maternal and neonatal sepsis and mortality. The A-PLUS trial includes two primary hypotheses, a maternal hypothesis and a neonatal hypothesis. First, a single, prophylactic intrapartum oral dose of 2 g azithromycin given to women in labor will reduce maternal death or sepsis. Second, a single, prophylactic intrapartum oral dose of 2 g azithromycin given to women in labor will reduce intrapartum/neonatal death or sepsis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The A-PLUS Trial is a randomized, placebo-controlled, parallel multicenter clinical trial. The study intervention is a single, prophylactic intrapartum oral dose of 2 g azithromycin, with a comparison with a single intrapartum oral dose of an identical appearing placebo. For the A-PLUS randomized control trial (RCT), a total of 34,000 laboring women from eight research sites in sub-Saharan Africa, South Asia, and Latin America will be randomized with one-to-one ratio to intervention/placebo. In response to the global coronavirus pandemic, research sites will also collect data on COVID-19 signs/symptoms, diagnosis, and treatment in order to estimate the incidence of infection and evaluate the impact of the pandemic on the target population.

Prior to the initiation of the A-PLUS RCT, research sites will conduct an observational pilot study using the RCT's planned infrastructure in order to characterize the current practices at participating research facilities and optimize the identification of suspected infection for the RCT. The information obtained in the pilot study will be used to validate estimates of intrapartum deaths, maternal sepsis, and neonatal sepsis used in the sample size calculations for the RCT. Finally, the pilot study will allow the research sites to inventory and upgrade local capacity to conduct routine cultures during the RCT.

A maximum of 16,000 women, separate from the sample for the main trial, will be enrolled in the pilot, across all eight research sites, with no more than 2000 women enrolled at any individual site. Research sites will be eligible to transition to the RCT when a minimum of 600 participants have been enrolled in the pilot study with evidence of (a) high rates of follow-up; (2) acceptable data quality and completeness; and (3) there are no concerns about identification and reporting of infection.

Given the clinical benefits of intrapartum azithromycin so far reported in two trials and the likelihood that it may become the usual practice if the investigator's large RCT confirms the reported benefits, it is important to monitor antibiotic resistance to determine the safety of azithromycin prophylaxis. Therefore, the RCT will also include an ancillary study (referred to as the antimicrobial resistance (AMR) sub-study) to monitor antimicrobial resistance and maternal and newborn microbiome effects of the single dose of prophylactic azithromycin using the following methodology

1. For all mothers enrolled in the RCT and their infants:

a. Routine clinical monitoring at baseline and three post-partum time points (3 days, 7 days, and 42 days), with culture and sensitivity testing in cases of suspected bacterial infections;
2. Among a subset of 1000 randomly selected maternal-infant dyads:

1. Serial susceptibility monitoring of antimicrobial resistance patterns (including azithromycin resistance) from selected maternal and newborn flora through culture and sensitivity testing. Serial monitoring will be conducted at baseline and three post-partum time points (1 week, 6 weeks, and 3 months).
2. Serial microbiome collection and storage of specimens for future testing to monitor maternal and newborn microbiome status of selected sites.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

Randomized, placebo-controlled, parallel multicenter clinical trial. Women in labor will be randomized with one-to-one ratio to intervention/placebo.
Primary Study Purpose

PREVENTION

Blinding Strategy

TRIPLE

Participants Caregivers Investigators
Both the azithromycin and placebo will be procured from the same manufacturer. The packaging will be standardized across sites and will be labeled as: "Azithromycin 2 g or Placebo", with the expiration data and a unique identifier.

Clinical and research staff as well as the women will be masked to treatment status unless there is a serious adverse event potentially related to the treatment modality that requires unmasking for safety reasons. There will be one pharmacist at each site who will monitor randomization, drug supply, and safety. If concerns about randomization or participant safety are identified, the data coordinating center will authorize and instruct the study pharmacist to apply un-masking procedures.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.
