  • The Company is evaluating ADG20 in Phase 1 single ascending dose study of ADG20 ex vivo against SARS-CoV-2. 
  • Data from a six-month evaluation timepoint confirmed the extended half-life of ADG20, which approached 100 days based on data from the 300 mg intramuscular (IM) dose that was given as a single injection. 
  • In addition, 50% serum virus neutralization titers at six months after a 300 mg IM dose of ADG20 were similar to observed peak titers with the Moderna Inc's MRNA mRNA-1273 vaccine and exceeded those achieved with the AstraZeneca Plc's AZN AZD1222 vaccine series, the Company reported.
  • ADG20 was well-tolerated with no study drug-related adverse events (AEs), serious AEs, or injection-site or hypersensitivity reactions.
  • Participants will continue to be followed through for 12 months.
  • Adagio anticipates that the data will support an Emergency Use Authorization application in Q1 of 2022.
  • Data from quantitative systems pharmacology/whole-body physiologically based modeling support evaluation of 300 mg intramuscular dose of ADG20 as a single injection in Phase 2/3 studies
  • Price Action: ADGI stock is up 1.19% at $40 during the market session on the last check Wednesday.
