23andMe Announces FDA Clearance of IND Application for its Dual Mechanism Antibody, 23ME-01473, Targeting ULBP6
INDImmunotherapy
23ME-01473 (‘1473) seeks to treat cancer by restoring anti-tumor immunity through NK and T cells
‘1473 has dual mechanisms of blocking the immunosuppressive effects of soluble ULBP6, and inducing Fc receptor-mediated killing of ULBP6-expressing cancer cells through enhanced effector function
Phase 1 clinical study in patients with solid tumors to commence in H1 2024
The target for ‘1473 was discovered through 23andMe’s proprietary research platform, the world's largest recontactable database of de-identified human genetic and phenotypic information
Jan. 31, 2024 -- 23andMe Holding Co. (Nasdaq: ME) (23andMe), a leading human genetics and biopharmaceutical company, announced the U.S. Food and Drug Administration (FDA) has cleared the investigational new drug application for 23ME-01473 (‘1473), a natural killer (NK) cell activator intended to treat cancer. 23andMe plans to evaluate ‘1473 in participants with advanced solid tumors in a Phase 1 clinical study beginning in the first half of 2024.
‘1473 targets ULBP6 to restore anti-tumor immunity through NK and T cells. ULBPs are stress-induced ligands found on the surface of cancer cells that bind to their receptor, NKG2D, on NK and T cells. Cancers escape immune cell recognition by shedding ULBP ligands from their cell surface, which act as immunosuppressive molecular decoys.
Blocking the binding of soluble ULBP6 to NKG2D may restore immune cell recognition and killing of cancers. Further, ‘1473 is Fc-effector enhanced, which provides an additional mechanism for NK cells to induce cell death of ULBP6-expressing cancer cells.
'1473 also has the potential to address a major unmet need in cancer treatment: patients who may have or may develop tumor resistance to checkpoint inhibitors. By combining NK and T cell activation, '1473 may initiate a broader and deeper response of the immune system to kill cancer cells, and delay tumor resistance seen in treatment with traditional checkpoint inhibitors.
“This program further validates the 23andMe database as a proven resource for identifying novel therapeutic targets,” said Jennifer Low, Head of Therapeutics Development, 23andMe. “The team is excited to initiate our next immuno-oncology program, ‘1473, which is particularly interesting given its two mechanisms of action, which may synergize to enhance NK and T cell immunity against certain tumors.”
