We previously described a computationally-designed, homotrimeric miniprotein inhibitor, designated TRI2-2, that protects mice against pre-Omicron SARS-CoV-2 variants. Here, we show that TRI2-2 exhibits broadly neutralizing activity of SARS-CoV-2 variants and protects mice against BQ.1.1, XBB.1.5 and BA.2.86 challenge when administered intranasally post-exposure. The resistance of TRI2-2 to viral escape by most variants and the ability to deliver it directly to the upper airways highlight the potential of the multivalent miniprotein inhibitor as an alternative therapeutic modality. The computationally designed TRI2-2 miniprotein inhibitor protects against multiple SARS-CoV-2 Omicron variants.,Lee J, Case JB, Park YJ, Ravichandran R, Asarnow D, Tortorici MA, Brown JT, Sanapala S, Carter L, Baker D, Diamond MS, Veesler D Commun Biol. 2026 Jan 10. doi: 10.1038/s42003-025-09499-2.
