UNITE: Immunotherapy Platform

About the UNITE platform

Immunomic Therapeutics’ investigational UNITE platform is founded in a combination of complementary technologies and capabilities: ITI’s proprietary lysosomal targeting technology, optimal use of adjuvants, antigen selection and optimization, a breadth of delivery methods, and the ability to manufacture material at a large scale. Immunomic Therapeutics’ nucleic acid vaccines have the potential to utilize the body’s natural biochemistry to develop a broad immune response including antibody production, cytokine release and critical immunological memory. This approach could put UNITE at the crossroads of immunotherapies in a number of illnesses, including cancer, allergy and infectious diseases. ITI’s lysosomal targeting technology is currently being employed in a Phase II clinical trial as a cancer immunotherapy.

We are also collaborating with academic centers and biotechnology companies to study the use of the UNITE platform in cancer types of high mortality, including cases where there are limited treatment options like glioblastoma and acute myeloid leukemia. We believe that these early clinical studies may provide a proof of concept for UNITE in cancer, and if successful, set the stage for future studies, including combinations in these tumor types and others. Preclinical data is currently being developed to explore whether the UNITE platform may amplify and activate the immune response in highly immunogenic tumor types and be used to create immune responses to tumor types that otherwise do not provoke an immune response.

Mode of Action

The UNITE platform may enable a broad and robust immune response by exploiting the pathways and associated effect of activated antigen presenting cells. Where the lysosomal targeting technology can drive antigen presentation through the MHC II compartment, resulting in a Th1 polarization, both cross presentation to the MHC I and exosomal release of antigen can result in a comprehensive immune response. The UNITE platform could support this activity by combining the nucleic acid vaccine with select adjuvants and the appropriate delivery method.

ITI MoA

The platform can result in a number of downstream effects: CD4+ memory, cytokine production, and a potent antibody response. These factors are currently under intense focus in the cancer immunotherapy landscape. It is important to note that, while the mechanism of lysosomal targeting appears to focus on enhancing presentation of antigen to CD4+ T cells and producing a Th1 type CD4+ T cell response (an aspect missing in other platforms), the UNITE platform, as a whole, is believed to induce a broad immune response and can result in enhanced CD8+ T cell responses as well.

Pipeline

Our allergy assets remain an underpinning of Immunomic Therapeutics’ success, and have enabled our pivot to focus on oncology.

In addition to our canine atopic dermatitis vaccine concept,  our vaccines using ITI’s lysosomal targeting technology have already been tested in several clinical studies in both allergy and oncology.

ITI pipeline - 2018

In expanding the work being done that populates our pipeline, three distinct programs have been developed that focus on slightly different approaches in oncology. The antigens present in different types of cancer can be classified into the following classes: viral, neoantigens, and other cancer antigens. Viral antigens comprise targets that are either associated with or directly cause certain cancers. A class called neoantigens are those which are derived from gene mutations. Other cancer antigens can be further divided into various sub-types, but many of them are marked by incorrectly timed or inappropriately expressed levels of specific proteins. Our focus on these classes will accelerate into development as we move forward.

We know that there are multiple aspects that inform our platform's success. While research is the essential engine that drives our technology forward, our efforts in process development, manufacturing management, and regulatory affairs are critical factors that advance the Immunomic Therapeutics vision.
