Schizophrenia
Emraclidine was the centerpiece of AbbVie’s $8.7 billion acquisition of Cerevel in December 2023 but failed two mid-stage trials. Tavapadon, meanwhile, has been a more rewarding asset for the pharma, clearing three Phase III Parkinson’s studies in 2024.
Among the 55 novel drugs that crossed the regulatory finish line last year were notable new mechanisms of action, coming particularly in the oncology and neurosciences spaces.
This year saw lofty highs and devastating lows for neuroscience drug developers like Bristol Myers Squibb, Eli Lilly and AbbVie, following the predictable pattern of successes and failures that characterizes this space.
Some 90% of investigational drugs fail—and success rates are even more dire in the neuro space. Here, BioSpace looks at five clinical trial flops that stole headlines over the past 12 months.
Tavapadon improved motor and daily living complications at week 26. The news comes nearly one month to the day after AbbVie announced the Phase II failure of another key Cerevel asset, emraclidine.
With the failure of AbbVie’s emraclidine in two mid-stage trials, Bristol Myers Squibb’s Cobenfy is ‘sole muscarinic winner.’
A tale of two multi-billion schizophrenia deals, AstraZeneca touts strong sales while deflecting questions about an investigation into China exec, the Huntington’s pipeline builds momentum and layoffs continue with Sana Biotechnology and 23andMe.
The shocking failure of AbbVie’s emraclidine has investors questioning the Big Pharma’s long-term neuroscience strategy, which put the drug at the center of expectations.
Bristol Myers Squibb’s third-quarter results benefited from sales of its legacy brands Eliquis and Revlimid, as well as growth portfolio products such as Abecma, Breyanzi and Reblozyl.
Bristol Myers Squibb wins approval for the first novel schizophrenia drug in decades; Pfizer pulls Oxbryta from the market; new IVF and abortion laws could derail women’s health research; Roche touts CDK inhibitor deal and obesity pipeline and BioSpace heads to Meeting on the Mesa.
