ImmTORTM to amplify the efficacy and reduce immunogenicity of biologics.

Brunn, Carsten; Kishimoto, Takashi Kei

In recent months as vaccines against the SARS-CoV-2 virus continue to rollout across the globe, there has been a renewed interest in ways to activate or ignite the immune system. For a vaccine to be effective, it must be immunogenic and specific to provoke the body's defenses to mount an effective response that protects the host from disease. However, there are other situations wherein the immune system mounts an unwanted immune response that can be detrimental to health, either directly, by causing an autoimmune disease, or indirectly, by compromising the safety and/or efficacy of biologic drugs. In these scenarios, it would be desirable to have a 'tolerogenic vaccine' that could selectively and effectively mitigate these unwanted immune responses. ImmTORTM, a nanoparticle technology, is being developed to address the issue of immunogenicity for gene therapy vectors and other biologic drugs. By targeting antigen-presenting cells, ImmTORTM has the potential to amplify the efficacy of biologic therapies and unlock the full potential of such treatments to improve the lives of those who suffer from serious and debilitating diseases.
