Feb 29 (Reuters) - GSK said it agreed to confidentially settle another lawsuit in California that had alleged its discontinued heartburn drug Zantac caused cancer, the latest in a series of settlements made by the British drugmaker to end costly litigation.

The case, which was set to begin trial on April 2, will be dismissed. GSK does not admit to any liability in this settlement with Boyd/Steenvoord, it said on Thursday. (Reporting by Eva Mathews in Bengaluru; Editing by Rashmi Aich)
