REUTERS/Phil Noble/File Photo Acquire Licensing RightsOct 18 (Reuters) - Shares in AstraZeneca (AZN.L) fell more than 4% on Wednesday after a data abstract on its experimental precision drug's use in lung cancer patients in a late-stage trial disappointed some analysts. Fernandez added that progression-free survival in lung cancer patients came in below expectations. Barclays analyst Emily Field also said in a note that safety looked better than expected for lung cancer patients and the data abstracts were "collectively positive" for AstraZeneca. London-listed shares of AstraZeneca were down 3.7% at 1219 GMT, while the broader STOXX Health Care (.SXDP) index was off 1%. Shares of AstraZeneca's Japanese partner Daiichi Sankyo (4568.T), which is jointly developing the cancer drug, closed 4.6% lower on Tuesday.
