About this study
Official title: Open-Label, Expanded Access Protocol of a Human Monoclonal Antibody, Ansuvimab (mAb114), Administered As a Therapeutic to Ebola-Infected Patients or As a High-Risk Ebola Post-Exposure Prophylaxis
The human monoclonal antibody (mAb), ansuvimab (mAb114), will be provided to Ebola-infected patients as either a treatment or as PEP under an expanded access protocol. Ansuvimab is administered at 50 mg/kg as a single intravenous (IV) infusion
Read the detailed description
This is an open-label, intermediate-size patient population, expanded access protocol (EAP) of ansuvimab administered once by IV infusion at a dose of about 50 mg/kg (weight-based dosing). Participants will be monitored and assessed daily for safety, including clinical observation, laboratory monitoring, the incidence of adverse events (AEs) and serious adverse events (SAEs) as defined by protocol, including AEs that by clinical judgement are atypical for orthoebolavirus zairense (EBOV) in infected patients, and any AEs that occur during product infusions. PEP participants will be followed to determine outcome following ansuvimab administrations through the study period for EBOV status (positive/negative). Blood will be collected for protocol-specific assessments and RT-PCR evaluation of viral load by available assay. A blood sample for Ebolavirus viral load measurement will be collected before mAb114 administration and at subsequent study time points per the Schedule of Evaluations. Participants will be followed for a period as defined by protocol after the product administration. Survival status for infected patients and follow up for PEP participants for signs/symptoms of EBOV will be recorded as applicable.
Ansuvimab will be provided for expanded access in any EBOV outbreak location as authorized by the applicable Regulatory Authorities and/or Ethics Committee(s).

Questions about this trial
What is this clinical trial studying?
A study testing Ansuvimab in people with Ebola Virus Disease, run by Ridgeback Biotherapeutics, LP.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 17 Dec 2024. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Sabue Mulangu, MD,DTMH,PhD (+1 786 687 24951, EAP-requests@ridgebackbio.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05067166, which also lists 11 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
