Antengene Corporation Limited announced that it has entered into a clinical trial collaboration with BeiGene to evaluate the safety, pharmacokinetics, pharmacodynamics and preliminary efficacy of selinexor in combination with BeiGene's anti-PD-1 checkpoint inhibitor, tislelizumab. This multi-center, open-label Phase I/II trial will evaluate the investigational combination as a potential treatment option for patients with T and NK-cell lymphoma. Tislelizumab is a PD-1 inhibitor designed to help aid the body's immune cells to detect and fight tumors.
Tislelizumab, a humanized monoclonal antibody, is specifically designed to minimize binding to Fc?R on macrophages. In pre-clinical studies, binding to Fc?R on macrophages has been shown to compromise the anti-tumor activity of PD-1 antibodies through activation of antibody-dependent macrophage-mediated killing of T effector cells.
