About Addimmune

We Imagine a World Without HIV

Addimmune was founded in 2023 to pursue promising gene therapy technologies that treat and cure HIV.

Our revolutionary new gene therapy technology has the power to transform the lives of millions of people living with HIV.

The Power to Transform Millions of Lives

Our gene therapy technology is so effective because it allows us to “edit” a cell’s operating system, its DNA. By editing a cell’s DNA, we can insert or delete commands to change or improve the function of our cells.

AGT103-T Success Deserves Sole Focus

This life-changing approach to HIV has been made possible by 15 years of pioneering research & development by American Gene Technologies (AGT™). AGT created Addimmune as a separate company in 2023.

Why a separate company? Because the Phase 1 clinical trial of AGT103-T (its gene therapy for HIV) was so successful that AGT decided the HIV cure program deserves to be the sole focus of one business.

Addimmune Was Formed to Advance a Phase 2 HIV Clinical Trial

The formation of Addimmune enables AGT to focus on its gene therapy research on diseases, like PKU and cancer. Today, Addimmune is an innovation engine designed to free the world from HIV.
