Results from a clinical trial completed in Kenya have determined that a safe dose of the antibiotic, fosfomycin, can be used to treat babies with neonatal sepsis. This is a significant development, as there are very few antibiotics specifically licensed to treat multidrug-resistant infections in babies. This research was lead by Dr Christina Obiero and Professor Jay Berkley.

Winnie Mkare and her four children. The baby Patience developed a dangerously high temperature and was diagnosed with neonatal sepsis. Patience received treatment and is today recovering at home.
Winnie Mkare lives with her husband and four children in Matano Manne village, an hour’s drive from the nearest hospital. Shortly after the birth of her daughter, Patience, the baby developed a dangerously high temperature. Patience was rushed to the paediatric ward of the Kilifi District Hospital where she was diagnosed with neonatal sepsis. Winnie says she didn’t know if her daughter would survive. Patience was able to receive treatment and is today recovering at home with her family.

The NeoFosfo trial investigated the pharmacokinetics (PK) and safety of fosfomycin in 120 babies aged under 28 days who were hospitalized with clinically diagnosed sepsis at the Kilifi County hospital in Kenya. The PK studies define which dose to use in babies.

The trial was sponsored by the Global Antibiotic Research and Development Partnership (GARDP) and the Drugs for Neglected Diseases initiative (DNDi) and supported by key partners.

“This is a very encouraging outcome for the treatment of neonatal sepsis and the care of babies who are hardest-hit by rising antimicrobial resistance (AMR),” said Neonatal Sepsis Project Leader for GARDP, Sally Ellis. “The study provides crucial evidence of the correct dosage of fosfomycin for newborns.”

Published in Archives of Diseases in Childhood Randomised controlled trial of fosfomycin in neonatal sepsis: pharmacokinetics and safety in relation to sodium overload indicated that fosfomycin offered significant potential as part of a combination antibiotic regimen for newborns, which is safe, easily administered, and affordable.

The paper comes after recent data showed that Sub-Saharan Africa has the highest overall burden of AMR in the world, and that babies in particular are most affected. The GRAM study, published in The Lancet in January 2022, revealed that children under five years old made up over half of the 255,000 people in Sub-Saharan Africa who died in 2019 because of AMR.

Neonatal sepsis is a life-threatening condition that requires prompt detection and treatment. Newborns - babies under 28 days old - are particularly vulnerable as their underdeveloped immune systems struggle to fight infections. This is complicated by drug resistance, as up to 40% of bacterial infections are resistant to standard treatments. Many newborns die if they don’t get timely treatment, while others may have significant long-term consequences.

“Currently there are very limited antibiotics in the pipeline. Safe and affordable antibiotic combinations effective against bacteria causing sepsis in babies are needed to improve survival. Our results are significant as they provide evidence that fosfomycin is safe and can now be taken forward into further clinical trials focusing on improving mortality outcomes for sepsis in babies,” said clinical investigator on the trial, Christina Obiero of the KEMRI-Wellcome Trust Research Programme in Kilifi, Kenya.

Fosfomycin is an antibiotic that is used in some countries to treat serious bacterial infections but has rarely been used for treatment of serious infection in babies admitted to hospitals. It is an off-patent antibiotic and thus potentially inexpensive, and has been identified as ‘critically important’ by the World Health Organization (WHO). 

The results of the NeoFosfo trial will be followed by a large GARDP-led international clinical trial, NeoSep, which will enrol three thousand babies, including in Kenya and South Africa. It will obtain robust evidence of the safety and efficacy of new antibiotic combinations including fosfomycin, compared to other WHO-recommended and existing antibiotic combinations, for the treatment of neonatal sepsis.

It is expected that results obtained from this trial could inform WHO and local antibiotic treatment guidelines, as partners aim to demonstrate which combinations are safe and effective in treating neonatal sepsis.

GARDP is committed to accelerating the development of lifesaving treatments for drug-resistant infections and transforming the care of babies with sepsis.

About GARDP

The Global Antibiotic Research and Development Partnership (GARDP) is a Swiss not-for-profit organization developing new treatments for drug-resistant infections that pose the greatest threat to health. GARDP was created by the World Health Organization (WHO) and the Drugs for Neglected Diseases initiative (DNDi) in 2016 to ensure that everyone who needs antibiotics receives effective and affordable treatment, no matter where they live. We aim to develop five new treatments by 2025 to fight drug-resistant infections, focusing on sexually transmitted infections, sepsis in newborns and infections in hospitalized adults and children. GARDP is funded by the governments of Germany, Japan, Luxembourg, Monaco, Netherlands, South Africa, Switzerland, United Kingdom, as well as Médecins Sans Frontières and private foundations. GARDP is registered under the legal name GARDP Foundation.

Taking relationships seriously

Community Engagement (CE) is a critical aspect of health research because of its potential to make research more ethical, relevant, and well implemented. Many research programmes now aim to incorporate CE activities at all stages of their work. This KWTRP brief summarises key findings from a malaria trials, and provides an illustration of how CE works more generally. It highlights facilitators and challenges to engagement, and the ethical issues that are particularly relevant in LMIC settings with under resourced health systems.

The KEMRI-Wellcome Trust Research Programme today released the results of its latest modelling on COVID-19 vaccine scale-up within the country. The analysis found that the country’s COVID-19 vaccination campaign can achieve greater value for money if it focuses on the elderly, rather than a strategy that pursues scaling up vaccines to the whole population.

Large African and South Asian research network finds half of deaths among children admitted to hospital happens after discharge

Young children in sub-Saharan Africa and South Asia who become sick or malnourished continue to have a high risk of death in the six months after being hospitalized, according to findings by researchers in the Childhood Acute Illness & Nutrition (CHAIN) Network. Appearing in The Lancet Global Health, the study of 3,101 acutely ill children at nine hospitals in six countries across sub-Saharan Africa and South Asia found that 48% of the 350 deaths recorded occurred within six months after discharge from hospital.
