A Single Vision for Multiple Cytokine Inhibition

Bioniz was founded on an idea that small peptides could be rationally designed to selectively inhibit functionally redundant cytokines by targeting receptors that are shared within a family of cytokines. Many diseases are driven by the collective dysregulation of multiple cytokines and are, therefore, inherently beyond the reach of current therapies, which lack either the breadth or the specificity to address this more complex pathology.

Our M3 Technology platform dissects the evolutionary biological concept of “redundancy” that exists within families of cytokines, which is defined as several cytokines sharing a common receptor and therefore exhibiting redundant functionality. It has become increasingly understood that members of a cytokine family possess overlapping responsibilities to ensure the vital maintenance of an immune response in the event the primary family member is either disrupted or dysregulated.

Our core value proposition is to selectively inhibit cytokine members within a family while allowing non-blocked members to continue providing immune function. Our breakthrough technology has allowed us to generate first-in-class peptides to achieve this goal. We rationally design our peptides to occupy select binding pockets on the common receptor that are highly specific for targeted members of the cytokine family. By inhibiting selected cytokines while leaving redundant family members free to bind to the common receptor, we can broaden the degree of cytokine blockade that is achievable while normal systemic immune functionality is preserved.

BNZ-1 is our lead investigational drug. It is a peptide that targets the shared receptor (γc) in the IL-2 family of cytokines that is utilized by all six family members (IL-2, IL-4, IL-7, IL-9, IL-15 and IL-21). BNZ-1 selectively inhibits IL-2, IL-9, and IL-15, but not the other cytokines in this family. BNZ-1 blocks the excessive activity of IL-2, IL-9 and IL-15 in diseases where these cytokines are implicated. The other undisrupted cytokines, IL-4, IL-7, and IL-21, protect the normal immune balance through their redundant functions.
