Randomized, Double-blind, Placebo-controlled, Phase Ib Study to Assess the Safety and Immunogenicity of MVA-MERS-S_DF-1

2019-10-15 11:11:26 | BioPortfolio


The study will be a two center, randomized, double blind, placebo controlled study of the MVA MERS S_DF-1 candidate delivered by i.m. injection. To evaluate the MERS-S-specific antibody responses and safety profile induced by the two dosage levels of MVA-MERS-S_DF-1 the data will be compared to a placebo control group.


This will be a Phase Ib, two-center study in approximately 160 healthy adults aged 18-55 years

The study is separated in two parts:

Part A:

The study starts with a single center open-label run-in phase of two dose levels (cohort 1 "low dose": 2x10^7 PFU, cohort 2 "high dose": 2x10^8 PFU) in 10 healthy subjects. 5 subjects will be allocated to each dose cohort and will receive immunization on day 0 and day 28.

Part B:

Two-center, randomized, double-blind, placebo-controlled, dose-finding study. This part is a double-blinded trial in approximately 150 healthy subjects. Subjects will be allocated to two different dose cohorts and a placebo cohort; each receiving three vaccine injections.

Medical and Biotech [MESH] Definitions

A coronavirus first reported in the summer of 2012 in a pneumonia patient in SAUDI ARABIA. It is related to SARS VIRUS. MERS-CoV has an estimated incubation period of 12 days and symptoms include renal failure and severe acute pneumonia with often fatal outcome.

The dose amount of poisonous or toxic substance or dose of ionizing radiation required to kill 50% of the tested population.

A genus of the family CORONAVIRIDAE which causes respiratory or gastrointestinal disease in a variety of mostly mammals. Human betacoronaviruses include HUMAN ENTERIC CORONAVIRUS; HUMAN CORONAVIRUS OC43; MERS VIRUS; and SARS VIRUS. Members have either core transcription regulatory sequences of 5’-CUAAAC-3’ or 5’-CUAAAC-3’ and mostly have no ORF downstream to the N protein gene.

A treatment schedule in which the total dose of radiation is divided into large doses.

Mice selectively bred for hypersusceptibility to two-stage chemical skin carcinogenesis. They are also hypersusceptible to UV radiation tumorigenesis with single high-dose, but not chronic low-dose, exposures. SENCAR (SENsitive to CARcinogenesis) mice are used in research as an animal model for tumor production.
