The Sabin Marburg vaccine is the only candidate currently slated for a Phase 2 clinical trial. Marburg is among the world's deadliest viruses, resulting in the death of approximately half the people the virus infects. Currently, there are no approved vaccines or treatments for the disease. As recently as July this year, two people in Ghana died after being infected with Marburg virus, reinforcing the urgent need for medical therapies.

The latest tranche of funds enables Sabin to conduct a randomized, blinded, placebo-controlled clinical trial among adults in the U.S. to further evaluate the safety and the efficacy of the Marburg vaccine candidate and advance non-clinical vaccine dosing studies. The Phase 2 clinical trial in the U.S. will begin after Sabin has initiated a same-stage trial in Africa, currently scheduled for 2023. Sabin will also undertake a non-clinical study on the vaccine candidate during this phase.

"Beginning Phase 2 clinical trials for the Marburg vaccine is a pivotal milestone for us and we appreciate BARDA's continued confidence in our work and support for this critical next step," says Sabin Chief Executive Officer Amy Finan. "Vaccines remain our best bet against death and disability from deadly viruses. I am hopeful that in the years ahead, we can offer this life-saving vaccine to every person who needs it."

In 2019, BARDA awarded Sabin a multi-year contract valued at $128 million to further the development of vaccines against two lethal viruses: Marburg and Ebola Sudan. With BARDA now exercising the latest option of that contract, Sabin's Ebola and Marburg Research & Development program, to date, has been awarded $98.6 million.

BARDA is part of the Administration for Strategic Preparedness and Response within the U.S. Department of Health and Human Services. This project has been funded in whole or in part with federal funds from the Department of Health and Human Services; Administration for Strategic Preparedness and Response; Biomedical Advanced Research and Development Authority, under contract number 75A50119C000555.

About Ebola Sudan and Marburg

Ebola Sudan and Marburg are members of the filovirus family. Both can cause severe hemorrhagic fever in humans and nonhuman primates. No therapeutic treatment of the hemorrhagic fevers caused by filoviruses has been licensed to date. Marburg and Ebola viruses are transmitted to humans by infected animals, particularly fruit bats. Once a human is infected, the virus can spread to others through close personal contact or contact with bodily fluids. Isolation of infected people is currently the centerpiece of filovirus control.

Marburg was the first filovirus to be recognized in 1967 when outbreaks of hemorrhagic fever were reported in a few Europe-based laboratories including in the town of Marburg, Germany. Ebola was identified in 1976 when two simultaneous outbreaks occurred in northern Zaire (now the DRC) in a village near the Ebola River and southern Sudan. The outbreaks involved what eventually proved to be two different species of Ebola virus; both were named after the nations in which they were discovered.
