WANTAIM: Women And Newborn Trial of Antenatal Interventions and Management

Currently recruiting: 
Yes
The challenge: 

Women in many low-income countries worldwide face a high and unacceptable burden of adverse pregnancy outcomes. Curable, sexually transmitted and genital infections (STIs), such as chlamydia, gonorrhoea, trichomonas and bacterial vaginosis, are major contributors to this disease burden but the majority of infections go untreated because most infections are asymptomatic, and affordable, easy to use and accurate diagnostic tests are unavailable in such settings. At the same time, there is conflicting evidence on the potential risks and benefits of STI screening and treatment in pregnancy, hindering policy and practice and leading to calls for definitive field trials.

The project: 

The aim of the WANTAIM Trial is to measure the effectiveness, health system requirements, cost-effectiveness and acceptability of antenatal point-of-care testing and treatment of sexually transmitted and genital infections to improve birth outcomes in high-burden, low-income settings.

The primary objective of the trial is to evaluate whether point-of-care testing and immediate treatment of curable STIs in pregnancy leads to a reduction in preterm birth and low birth weight compared with standard antenatal care.

The method: 

WANTAIM is a cluster randomised crossover trial being conducted at 10 sites in three provinces in Papua New Guinea. A total of 4600 pregnant women and their newborn infants will be enrolled and followed-up at participating antenatal clinics. Information on maternal and newborn health outcomes will be collected at 72 hours, 1 – 2 weeks and 4 – 6 weeks after childbirth.

The trial is expected to start recruitment in early 2017 and will take up to four years to complete.

The results: 

Trial results are anticipated in late 2019.

The impact: 

If antenatal point-of-care STI testing and treatment is proven to have an impact on birth outcomes, the WANTAIM Trial will hasten access to these technologies and could thereby improve maternal and neonatal health in all high-burden, low-income settings worldwide.
