Dose Escalation Study Assessing the Safety and Immune Response of PPV-06 Vaccine

Status:
Recruiting
Trial end date:

Target enrollment:

Participant gender:
All
Summary
PPV-06 immunotherapy targets interleukin-6 (IL-6), a key molecule of the immune system whose overproduction is implicated in many inflammatory and autoimmune diseases such as rheumatoid arthritis and osteoarthritis. The benefit of vaccination with PPV-06 is to induce, in response to immunizations, the production of antibodies directed against IL-6. The antibodies produced will neutralize the biological activity of IL-6 involved in the body's inflammatory process. The primary objective is to evaluate the safety/tolerability of vaccination with PPV-06.
