On July 12, 2022, Atara issued a press release updating the market on its preliminary analysis phase 2 EMBOLD study for product candidate ATA188. Atara stated, 'Based on the analysis of the EMBOLD data available at the time of the IA [interim analysis], there was not a sufficient dataset to draw conclusions about the predictive value of six months EDSS improvement for 12 months EDSS improvement. The IDSMC [Independent Data and Safety Monitoring Committee] believes the six-month interim endpoint may be an inaccurate measure of the potential of this intervention in this condition.' Following this news, Atara stock dropped sharply.
