About KHK4083/AMG 451
KHK4083/AMG 451 is an anti-OX40 fully human monoclonal antibody engineered with Kyowa Kirin’s patented POTELLIGENT® defucosylation technology to enhance its antibody-dependent cellular cytotoxicity (ADCC) activity. The initial KHK4083/AMG 451 antibody was discovered in collaboration between Kyowa Kirin US Research and La Jolla Institute for Immunology.
KHK4083/AMG 451 targets and inhibits the activity of the OX40 receptor expressed on the surface of effector T-cells, and has been shown to deplete activated OX40+ T-cells by ADCC. It has been reported that effector T cells expressing OX40 are present in the lesions of patients with atopic dermatitis and are critical in their development. Kyowa Kirin antibodies powered by POTELLIGENT technology with ADCC activity are currently marketed in several other therapeutic areas, including Oncology and Asthma. This potent antibody-enhancement platform is also licensed to numerous third parties throughout the biopharmaceutical industry.
On June 1, 2021, Kyowa Kirin entered into an agreement with Amgen (NASDAQ: AMGN) to jointly develop and commercialize KHK4083/AMG 451. Under the terms of the agreement, Amgen will lead the development, manufacturing, and commercialization for KHK4083/AMG 451 for all markets globally, except Japan, where Kyowa Kirin will retain all rights. If approved, the companies will co-commercialize the asset in the United States and Kyowa Kirin has opt-in rights to co-promote in certain other markets including Europe and Asia.
An overview of the KHK4083/AMG 451 Phase 2 Study
A Phase 2, multicenter, randomized, double-blind, and placebo-controlled clinical study (NCT03703102) was conducted in the U.S., Japan, Canada, and Germany to investigate the efficacy and safety of KHK4083/AMG 451. The study included 274 patients with moderate-to-severe atopic dermatitis, who were not adequately controlled with topical agents. The primary endpoint of the study was "percent change from baseline in Eczema Area and Severity Index (EASI) 1 at 16 weeks”.
About OX40
OX40 is a co-stimulatory molecule and a member of the tumor necrosis factor receptor (TNFR) superfamily. It has been reported that activated effector T cells express OX402,3 and are present in the lesions of patients with atopic dermatitis4. Professor Michael Croft, Ph.D., who is Director, Scientific Affairs, La Jolla Institute for Immunology helped identify that OX40 plays an important role in T cell proliferation, survival and formation of memory T cells5.
