AbbVie faces $3.5B loss after emraclidine fails phase 2 in schizophrenia

13 January 2025
In December 2023, pharmaceutical giant AbbVie made headlines with its acquisition of Cerevel Therapeutics for a substantial $8.7 billion. At the forefront of Cerevel's portfolio was emraclidine, a drug that had shown promise before a significant setback in its development. Despite the optimism surrounding emraclidine, the drug's failure in phase 2 clinical trials for treating schizophrenia has led to financial consequences for AbbVie, including a substantial impairment charge.

The phase 2 trials for emraclidine aimed to evaluate its efficacy as a once-daily, oral monotherapy for adults with schizophrenia experiencing acute exacerbations of psychotic symptoms. However, these trials did not meet their primary endpoints. Specifically, emraclidine did not demonstrate a significant difference from a placebo in the positive and negative syndrome scale total score, a key measure used in assessing schizophrenia symptoms. The disappointing results were publicly disclosed by the company in November.

As a result of this setback, AbbVie faces an impairment charge of approximately $3.5 billion. Despite this financial hit, the company remains optimistic about the remaining programs from Cerevel, which are estimated to hold a value of around $3.6 billion. AbbVie continues to assess and evaluate the clinical development programs associated with Cerevel, indicating that they are not yet ready to abandon these assets.

Aside from schizophrenia, emraclidine is also under investigation for its potential application in treating Alzheimer's disease. Notably, AbbVie had previously decided to discontinue another Alzheimer's-related project in July 2024, shortly before completing the acquisition of Cerevel. This decision underscores the challenges and complexities involved in developing effective treatments for Alzheimer's, a disease that has eluded medical breakthroughs for decades.

On a more positive note for AbbVie, another drug from the Cerevel acquisition, tavapadon, has shown encouraging results. Tavapadon successfully achieved its primary endpoint in a phase 3 clinical trial for Parkinson's disease. The subsequent analyses of these trials have exceeded the initial expectations of AbbVie's Chief Scientific Officer, Roopal Thakkar, M.D. The promising outcomes of tavapadon have prompted AbbVie to plan for a submission to the U.S. Food and Drug Administration (FDA) for approval within the year.

The contrasting fortunes of emraclidine and tavapadon illustrate the unpredictable nature of drug development and the inherent risks pharmaceutical companies take when investing in experimental treatments. While the failure of emraclidine poses a financial setback for AbbVie, the success of tavapadon offers a glimmer of hope and a potential opportunity for advancement in the treatment of Parkinson's disease.

The acquisition of Cerevel, despite its challenges, reflects AbbVie's commitment to expanding its research pipeline and exploring new therapeutic areas. As the company navigates the complexities of integrating Cerevel's assets, it remains to be seen how these developments will influence AbbVie's strategic direction and its pursuit of innovative solutions for challenging neurological conditions.
