Immune Response Clinical Trial
Official title:
A Phase I/II Randomized, Prospective, Double-blind, Placebo-controlled, Single-center Study to Evaluate the Ability of Sublingual MV130 to Induce the Expression of Trained Immunity in Peripheral Blood Cells
A mechanistic clinical trial with the aim to evaluate whether MV130 can induce the expression of a particular immune response (trained immunity) in peripheral blood cells. Therefore, the investigators are not evaluating efficacy in any disease or medical condition but rather assessing the immunological effect in immunogenicity of MV130 in healthy volunteers.
Bacillus Calmette-Guérin (BCG) has been postulated as a strategy to prevent transmission and reduce the incidence of infectious diseases due to its ability to induce trained immunity. However, it is not recommended to vaccinate with live-attenuated vaccines, such as BCG, to certain vulnerable populations including immunocompromised patients. This issue can be overcome with inactivated preparations that mediate trained immunity such as MV130. The safety of MV130 in pilot studies in patients with immunodeficiency or solid organ recipients, has been highlighted in recent studies. Based on the principles of trained immunity, it has recently been suggested that this concept can be further exploited in a next generation of anti-infectious vaccines: Trained immunity-based vaccines (TIbV). Thus, these vaccines may confer a broad protection far beyond to the nominal antigens they contain. ;
