CRO service industry is highly fragmented with the presence of numerous small and medium-sized limited-service providers, and a small number of large, full-service, global CROs. Smaller CROs face a few barriers while entering into the global market, whereas the full-service CROs with global capabilities needs to build the necessary infrastructure; moreover, they should be capable of simultaneously managing multiple complex testing services across different countries and regions, establishing the required relationships with strategic partners, developing relevant therapeutic expertise to serve the needs of their customers. Since the past few years, consolidation is emerging as a prominent trend across the CRO industry, which is followed by the majority of the prime players to strengthen their service offerings and garner the major market share in the global CRO market. For instance, Parexel International Corp. acquired The Medical Affairs Company in 2017. This has led to the generation of larger CROs benefiting pharmaceutical and biopharmaceutical companies through the wide geographic diversification, extensive therapeutic and development expertise, and enormous capital and technical resources to manage the demanding drug development programs, medical device designing and research, and regulatory affairs.
