AbbVie Inc.’s disappointing trial results for its new schizophrenia drug bode well for rival Bristol Myers Squibb Co., analysts said. On Monday AbbVie said that its Phase 2 trial investigating emraclidine as a once-daily oral monotherapy treatment for adults with schizophrenia did not meet the primary endpoint of showing a “statistically significant” improvement when compared with a placebo group.

AbbVie Inc. shares fell the most in three years after two mid-stage trials of its drug to treat schizophrenia failed to meet their primary goal, a blow to the company’s $8.7 billion acquisition of Cerevel Therapeutics earlier this year.

AbbVie’s experimental treatment for schizophrenia failed to significantly help patients in two trials, a blow to the company.
