BNZ-1: An IL-2, IL-9, IL-15 Inhibitor

The Company’s lead development candidate, BNZ-1, is a selective and simultaneous inhibitor of cytokines IL-2, IL-9 and IL-15. BNZ-1 has completed two Phase 1 studies.
 

T-cell Malignancies


Cytokines IL-2, IL-9 and IL-15 are potent T-lymphocyte growth factors and key disease drivers in multiple T-cell leukemias. T-cell leukemias, including Large Granular Lymphocyte (LGL) Leukemia and Cutaneous T-cell Lymphoma (CTCL), are a group of rare and often aggressive leukemias with no or limited treatment options resulting in a poor prognosis.

BNZ-1 inhibition of IL-15 prevents the proliferation of IL-15-dependent leukemic cells, while IL-2 & IL-9 blockade reduces the number and activity of Treg cells that enables a more robust immune system attack against malignant cells.

Bioniz has initiated a Phase 1 / 2 study with BNZ-1 in patients with LGL leukemia and refractory CTCL.
 

Alopecia Areata


Alopecia areata (AA) is a common autoimmune disease (~2% lifetime incidence), driven by T-cell attacks on hair follicles that have lost their immune privilege, which results in partial or complete loss of hair on the scalp and body. The onset of the disease can occur throughout life and equally affects both women and men. AA has been found to be associated with concurrent autoimmune disorders (e.g., vitiligo, atopy) and with serious psychological consequences, including anxiety and depression.

There are currently no pharmaceutical products approved by the U.S. Food and Drug Administration (FDA) for the treatment of AA. Broad-acting, intralesional steroids are the most commonly used therapy for AA, with varying degrees of success. Progress in developing effective, rationally targeted therapies has been historically limited by a lack of mechanistic understanding of the underlying key T-cell inflammatory pathways in AA. However, it has recently been demonstrated that IL-2, IL-9, and IL-15 are upregulated in AA lesions and are key drivers of the pathologic cytotoxic T-cell and natural killer cell activity in AA (Xing et al., 2014; Suarez-Farinas et al., 2015).

Bioniz plans to initiate a Phase 2 trial with BNZ-1 in patients with moderate to severe AA in 2018.

 

Clinical Trials Enrollment


Patients seeking information on enrollment in upcoming clinical trials for BNZ-1 are encouraged to check for information and updates on our ClinicalTrials.gov page by clicking here. Upcoming trials include a multiple ascending dose study examining safety and tolerability in healthy human subjects (for which patients are ineligible) and a Phase 2 dose ranging study for patients with Large Granular Lymphocyic Leukemia (LGLL) and Cutaneous T-Cell Lymphoma (CTCL).

As more information becomes available on other indications, ClinicalTrials.gov and this page will be updated in a timely fashion to reflect these changes.
