Merck 10Q: Global sales of Keytruda , an anti-PD-1 (programmed death receptor-1) therapy, were $881 million in the second quarter of 2017 compared with $314 million in the second quarter of 2016 and were $1.5 billion in the first six months of 2017 compared with $563 million in the first six months of 2016. Sales growth in both periods was driven by volume growth in all markets, particularly in the United States, as the Company continues to launch Keytruda with new indications. Sales in the United States continue to build across the multiple approved indications, in particular for the treatment of non-small-cell lung cancer (NSCLC). During the second quarter of 2017, Keytruda received four new indications in the United Sates and an additional indication in Europe.
