A box of Erlotinib 100mg tablets, also known by its brand name Tarceva, a cancer treatment drug manufactured by Roche Holding AG, sits alongside a blister pack of five tablets in this arranged photograph in London, U.K., on Friday, April 27, 2018. Tarceva, which is relatively unusual among cancer treatments in that it is given by mouth rather than injection, is for the initial treatment of people with EGFR mutation-positive metastatic non-small cell lung cancer.
