The company will release the data later this quarter.
Deutsche Bank said Tuesday it believes the stock price decline is an overreaction, as the firm used Achillion's timeline as guidance and does not see the lack of data as a delay.
The stock plunged despite Achillion's third-quarter earnings beat. The New Haven, CT-based company reported a loss of $15.7 million, or a loss of 16 cents a share, compared to a loss of $13.9 million, or 14 cents a share, in the same quarter one year ago. This was narrower than the consensus estimate of a loss of 18 cents a share from Zacks Investment Research.ACHN data by YCharts
