Globally, there is an urgency to develop effective, low-cost therapeutic interventions for coronavirus disease 2019 (COVID-19). We previously generated the stable and ultrapotent homotrimeric Pittsburgh inhalable Nanobody 21 (PiN-21). Using Syrian hamsters that model moderate to severe COVID-19 disease, we demonstrate the high efficacy of PiN-21 to prevent and treat SARS-CoV-2 infection. Intranasal delivery of PiN-21 at 0.6 mg/kg protects infected animals from weight loss and substantially reduces viral burdens in both lower and upper airways compared to control. Aerosol delivery of PiN-21 facilitates deposition throughout the respiratory tract and dose minimization to 0.2 mg/kg. Inhalation treatment quickly reverses animals’ weight loss after infection, decreases lung viral titers by 6 logs leading to drastically mitigated lung pathology, and prevents viral pneumonia. Combined with the marked stability and low production cost, this innovative therapy may provide a convenient and cos
Strategies to decrease low-density lipoprotein (LDL) cholesterol could help treat atherosclerosis. Here, Gennemark et al . developed an antisense oligonucleotide (ASO) that can be delivered orally, is taken up by the liver, and targets PCSK9, which regulates the LDL receptor. Subcutaneous administration of the ASO showed high potency in mice overexpressing PCSK9, a liver half-life of 18 days in monkeys, and reduced circulating PCSK9 in humans. The oral formulation showed 5 to 7% liver bioavailability compared to subcutaneous administration in rats and dogs, and it reduced LDL cholesterol in healthy monkeys. Results support the potential of this ASO for PCSK9 inhibition while avoiding the need for injections.
Inhibitors of proprotein convertase subtilisin/kexin type 9 (PCSK9) reduce low-density lipoprotein (LDL) cholesterol and are used for treatment of dyslipidemia. Current PCSK9 inhibitors are administered via subcutaneous injection. We present a highly potent, chemically modified PC
