ExpreS2ion announces upcoming presentation of Phase I/IIa malaria vaccine trial results by Jenner Institute
Horsholm, Denmark, October 18, 2016 – Today, ExpreS2ion Biotech Holding AB (“ExpreS2ion”) announces that its collaboration partner, Jenner Institute of the University of Oxford, will present the results from the Phase I/IIa clinical studies of its RH5.1 blood stage malaria vaccine at the annual American Society of Tropical Medicine and Hygiene (ASTMH) meeting on the 31st of October in New Orleans.
The study assesses the safety, immunogenicity, and efficacy of the blood-stage Plasmodium falciparum malaria antigen RH5.1, which is produced with ExpreS2ion’s technology platform ExpreS2.
“We are excited that the results from the Jenner Institute’s clinical Phase I/IIa malaria study can now be presented. Our ExpreS2 platform has been instrumental in the development of this vaccine, and we will of course announce our view on the results as soon as they become public,” says ExpreS2ion’s CEO Dr. Steen Klysner.
The RH5.1 vaccine
RH5.1 is a novel, recombinant malaria antigen developed at the Jenner Institute. It is based on a recombinant RH5.1 protein produced with the ExpreS2 platform using Drosophila Schneider-2 cells. RH5.1 is a part of a larger protein complex expressed by the malaria parasite during infection, helping it to invade red blood cells and causing the disease. The RH5.1 vaccine is intended to block red blood cell invasion and thus effectively block the progression of the disease.
The clinical study
The phase I/IIa study is funded by Leidos Inc as part of the company’s prime contract with the United States Agency for International Development (USAID) for the creation and testing of malaria vaccines.
The study has been running for more than a year to assess the safety, immune responses, dosing regimen and efficacy of RH5.1. The results will be presented by Angela M. Minassian from the Jenner institute of Oxford at a session at ASTHM in New Orleans, scheduled October 31, at 12:00 PM - 1:45 PM. The presentation will address safety as well as efficacy and durability of the vaccine response in healthy volunteers challenged with P. falciparum malaria parasites.

Malaria
Malaria is a major global problem, with 3.2 billion people living at risk of malaria infection. In 2015, malaria was thought to have caused 438,000 deaths, most of which (70%) occurred in children under five years old. Currently, there is no generally approved vaccine available for malaria, which means that there is a great need for a safe, effective malaria vaccine.
