Geeeez. You are talking about two entirely different drug combo therapies; one was with Tarceva and the other is with Tagrisso. We "pivoted" from combo with Tarceva to a combo with Tagrisso. Nothing has been leaked. There's no technical or non technical phase 3. Learn something about Fast Track and accelerate Review.
Phase 1 and 2 have been completed late 2019. Further clinical studies are underway (as of January, 2020). These studies may not be technically designated Phase 3. But, "further clinical studies are underway" (January, 2020). I believe that the results of these "further clinical studies" have been leaked to large investors resulting in 84 million share sales on the open market on Feb. 14.
