Abstract The emergence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants with potential resistance to existing drugs emphasizes the need for new therapeutic modalities broad variant activity. Here we show that ensovibep, a trispecific DARPin (designed ankyrin repeat protein) clinical candidate, can engage three units spike protein trimer SARS-CoV-2 and inhibit ACE2 binding high potency, as revealed by cryo-electron microscopy analysis. cooperative together...
Abstract Globally accessible therapeutics against SARS-CoV-2 are urgently needed. Here, we report the generation of first anti-SARS-CoV-2 DARPin molecules with therapeutic potential as well rapid large-scale production capabilities. Highly potent multivalent low picomolar virus neutralization efficacies were generated by molecular linkage three different monovalent molecules. These target various domains spike protein, thereby limiting possible viral escape. Cryo-EM analysis individual...
Abstract The prognosis of patients with acute myeloid leukemia (AML) is limited, especially for elderly or unfit not eligible hematopoietic stem cell (HSC) transplantation. disease driven by leukemic cells (LSCs), which are characterized clonal heterogeneity and resistance to conventional therapy. These therefore believed be a major cause progression relapse. We designed MP0533, multispecific CD3-engaging ankyrin repeat protein (DARPin) that can simultaneously bind three antigens on AML...
Abstract SARS-CoV-2 has infected millions of people globally and continues to undergo evolution. Emerging variants can be partially resistant vaccine induced immunity therapeutic antibodies, emphasizing the urgent need for accessible, broad-spectrum therapeutics. Here, we report a comprehensive study ensovibep, first trispecific clinical DARPin candidate, that simultaneously engage all three units spike protein trimer potently inhibit ACE2 interaction, as revealed by structural analyses. The...
PD-1/PD-L1 blockade has revolutionized the field of immunooncology. Despite relative success, response rate to anti-PD-1 therapy requires further improvements. Our aim was explore enhancement T-cell function by using novel PD-1-blocking proteins and compare with clinically approved monoclonal antibodies (mAbs). We isolated T-cells from ascites tumor 17 patients advanced epithelial ovarian cancer (EOC) analyzed effects mAbs nivolumab pembrolizumab two engineered ankyrin repeat (DARPin®...
