According to Igea Hub, the global cancer therapeutics market in 2017 was worth $121bn and it is predicted to reach $176bn in 2022. Blockbuster drugs are crucial to oncology’s continuing dominance of the pharma market; Igea Hub identifies Celgene’s Revlimid as the leading product, but others include Merck’s Keytruda and Bristol Myers-Squibb’s Opdivo.
