04 Dec, 2023:

Merus N.V Stock (MRUS) dropped by 6.13% from $25.13 to $23.59 in the trading on Monday December 04, 2023. The reason why MRUS stock down today is due to the updated data for lung cancer therapy. While the bispecific antibody cocktail impressed with partial responses in both first-line and later-stage patients, a high rate of adverse events, including lung issues, left investors wheezing. Fourteen patients even quit the trial due to side effects, raising concerns that MCLA-129's efficacy might come at a steep safety cost. As investors weigh the pros and cons, MRUS stock is plummeting sharply during the trading.
