Background Information

Specifically, the results showed improvements of 31.8% and 34.5% for two dosages of pemvidutide, while the placebo group achieved an improvement of only 25.9%.
Impact on Stock Price
Following the announcement of these trial results, the market reacted negatively. Altimmune's stock dropped significantly, closing down $4.10 per share, representing a fall of 53.18%, with the closing price reaching $3.61 per share on the same day.
