Archon is a biotechnology company developing computationally designed proteins to unlock powerful therapeutic targets that lie beyond the reach of existing modalities and to better treat disease. We directly apply generative protein design to create a new biologic class, Antibody Cages (AbCs), that integrates the industry-proven affinity and specificity of antibodies into self-assembling nanostructures. Precise control over AbC structure provides the ability to tune both how they distribute in the body and engage their cellular targets with high specificity and potency to establish a new gold-standard for biologic medicines.
