Compass Therapeutics Inc. experienced a significant decline of 75.15% in pre-market trading, hitting a 52-week low.
The company's recent clinical trial results for Tovecimig in combination with Paclitaxel showed an overall response rate of 17.1%, significantly higher than the 5.3% response rate for Paclitaxel alone. Despite this positive news, the stock price fell sharply, indicating a sector rotation as the broader market, represented by the Nasdaq-100, saw only a slight increase of 0.07%.
This decline in stock price, despite promising clinical results, reflects investor caution and market dynamics. Compass Therapeutics plans to engage with the FDA regarding these findings, which could influence future stock performance positively.
