Brief Summary

The rationale for transcutaneous vaccination is based on the unique ability of cutaneous immune cells, especially Langerhans cells (LCs), to present antigens to the immune system. DCs can be found at high densities in the epidermis and the dermis of human skin, a fraction of which are the epidermal LCs. It is known that strong and efficient immune responses can be induced by targeting vaccines to skin APCs (Glenn 2003, Partidos 2003), e.g. by epicutaneous application of smallpox vaccine on scarified skin. Several obstacles however prevent vaccines from attaining sufficiently high and free concentrations in these target skin DCs.

In this clinical trial we aim at testing the safety and immunogenicity of this new transcutaneous route of vaccine administration, first with a licensed, well-known, safe and highly immunogenic vaccine i.e. Tetagrip® vaccine, which is licensed for subcutaneous (s.c.) and intra-muscular routes (i.m), and to compare the induced vaccine-specific immune responses to those induced with the conventional (i.m) injection. We hypothesize that the transcutaneous application of Tetagrip® in the commercially available standard preparation of 0.5 ml should be capable to induce at least similar antibody and CD4 and/or CD8 T cell responses to both the tetanus and the flu vaccinal antigens.

This Phase I, open label, randomized study is designed to evaluate and to compare the safety and immunogenicity of a transcutaneous mode of Tetanus / Influenza vaccination to the conventional i.m. route of vaccine administration in two cohorts: The cohort I constituted of healthy volunteers and the cohort II of HIV-infected patients in whom the virus is stably controlled by antiretroviral therapy, ensuring an immune competence and a capacity to respond to vaccines.

Detailed Description

The proposed study aims to translate our current knowledge about vaccinology, immunology of the skin and on transcutaneous penetration of epicutaneously applied active compounds, into the development of more efficient and well tolerated vaccines, and to progress toward an easy-to-apply patch system for transcutaneous application of vaccines.

To that purpose we aim at testing the safety and immunogenicity of a new transcutaneous route of vaccine administration. We propose to test this new route first with a well-known, safe and highly immunogenic vaccine i.e. anti-influenza and tetanus vaccine which is licensed for sub-cutaneous and intra-muscular routes, and to compare the vaccine-specific immune responses induced after transcutaneous administration to the conventional intramuscular (i.m) injection. Seasonal vaccination against influenza is recommended for all individuals at risk for severe flu, including persons above 60 years of age or suffering from chronic diseases and for medical personal. It is also highly recommended at any age to prevent influenza. In addition vaccination against tetanus is mandatory in childhood and requires recall injections every 5 years to protect against the lethal disease caused by the tetanus toxin.

We hypothesize that the transcutaneous application of a licensed anti-influenza-tetanus vaccine in the commercially available standard preparation of 0.5 ml should be capable to induce at least similar antibody and CD4 and/or CD8 T cell responses to both the tetanus and the flu vaccinal antigens.

Tetagrip® vaccine is an approved and commercially available vaccine manufactured by Sanofi-Pasteur, administered in one injection for preventive vaccination of adults against tetanus and influenza. The Tetagrip® vaccine therefore represents a safe and approved test vaccine to evaluate safety and immunogenicity of the mode of administration under investigation.

The long term goal of this strategy is to improve the efficacy of vaccines that are currently encountering major obstacles such as the HIV vaccines, and to develop a non invasive mode of vaccine administration. Results from this study will help establish a standardized study protocol for the application of HIV-vaccines in future clinical trials.

STUDY DESIGN This Phase I, open label, randomized on the vaccine administration route study is designed to evaluate and to compare the safety and immunogenicity of a transcutaneous mode of Tetanus / Influenza vaccination to the conventional i.m. route of vaccine administration in two cohorts: The cohort I constituted of healthy volunteers and the cohort II of HIV-infected patients in whom the virus is stably controlled by antiretroviral therapy, ensuring an immune competence and a capacity to respond to vaccines.

• Written informed consent

Exclusion Criteria

In both cohorts, if any of the following apply, the subject cannot enter the study:

• Excessive terminal hair growth on the two investigational skin areas used for the transcutaneous mode of vaccination.
• Phototype V-VI
• Acute illness, e.g. fever, infection at screening and/or D0
