NEGATIVE IMPACT
Atara Biotherapeutics' stock was downgraded by multiple firms following the failure of its Phase 2 EMBOLD study of ATA188 to meet its primary endpoint.
The failure of a clinical trial is a significant negative event for a biotech company, as it indicates that the drug in question may not be effective. This can lead to downgrades from analysts, as they may believe that the company's future revenue potential is lower than previously expected. This is likely to have a negative impact on the company's stock price in the short term.
