BERLIN, Aug 23 (Reuters) - Roche (ROG.S) inadvertently published positive lung cancer drug trial data from an interim analysis, boosting the Swiss drug maker's shares even though more data will be needed to confirm the treatment's efficacy. Roche said on Wednesday that market participants had made it aware of the inadvertent disclosure of an interim data analysis on new immunotherapy tiragolumab, part of an experimental class of drugs known as anti-TIGIT. The data lifted Roche shares by 5% and sent shares of other companies testing anti-TIGIT drugs higher. J.P. Morgan analysts said the interim data suggested a survival benefit was within reach in the final analysis, but the clinical relevance remained uncertain. The unintended disclosure regards the second interim analysis of a Phase III trial known as Skyscraper 1.
