Ebola Treatment Trials Begin in DR Congo with Monoclonal Antibody and Antiviral Drug
Trials of two potential Ebola treatments—monoclonal antibody MBP134 and antiviral remdesivir—are set to commence next week at a hospital in the Democratic Republic of the Congo (DRC), according to a statement from the World Health Organization (WHO). The trials aim to evaluate the efficacy of these therapies in treating Ebola virus disease (EVD), which has caused multiple outbreaks in the region.
What Are the Key Details of the Trials?

The trials, led by the DRC’s National Institute for Biomedical Research (INRB) in collaboration with international health agencies, will enroll patients diagnosed with EVD. MBP134, a monoclonal antibody developed by Merck, targets the viral glycoprotein to prevent cell entry, while remdesivir, originally developed by Gilead Sciences for Ebola and later repurposed for COVID-19, inhibits viral replication. Both treatments have shown promise in preclinical studies but require rigorous human trials to confirm safety and effectiveness.
Why Is This Development Significant?
Ebola outbreaks in the DRC have historically posed severe public health challenges, with case fatality rates reaching up to 67% in some episodes. The introduction of new treatments could reduce mortality and improve outcomes, particularly in areas with limited healthcare infrastructure. The WHO emphasized that these trials align with its 2022 strategic framework to accelerate access to experimental therapies during outbreaks.
How Do These Treatments Compare to Existing Options?
Currently, the only approved Ebola treatment is the monoclonal antibody cocktail Inmazeb, which has demonstrated a 54% survival rate in clinical trials. MBP134 and remdesivir represent potential alternatives, with remdesivir’s broader antiviral profile raising questions about its applicability in resource-limited settings. Researchers will compare the two therapies against standard supportive care, including hydration and symptom management.
What Are the Next Steps?
The trials are expected to last several months, with preliminary results anticipated by early 2024. If successful, the treatments could be integrated into the DRC’s national response strategy, which also includes vaccination campaigns and community engagement efforts. The WHO has pledged to monitor the trials closely and share findings transparently to inform global health policies.
