Clinical Trials: World Market

2010-2025

Trends for outsourcing and off-shoring of clinical testing

The market for clinical trial services has been expanding rapidly, with impressive revenue growth and expansion of the sector in recent years.

Our new study shows how that sector will develop from 2010 onwards, with benefits to the pharma industry and clinical service providers. Clinical research organisations (CROs) are playing increasingly important roles in drug development worldwide, from conducting phase I trials to post-marketing studies.

Ageing populations, increasing prevalence of chronic diseases, growing demand for improved therapies and high growth of the pharmaceutical and biotechnology markets worldwide are driving the clinical trials sector and market. The globalisation of development programmes and the increasing complexity of trials - with regulatory developments - are heightening the need for larger trials and greater numbers of trials.

Many pharma companies are outsourcing clinical trials to gain cost savings/efficiencies, greater flexibility and specialist expertise. That trend will continue from 2010 onwards, our new study - Clinical Trials: World Market 2010-2025 - reveals. The emerging clinical trial destinations, including CEE countries, India and China, are achieving double-digit growth, our analyses show.

Our new report considers perspectives of sponsors and CROs for clinical trial outsourcing/off-shoring. We analyse the sector's strengths, weaknesses and financial prospects from 2010 to 2025 through quantitative and qualitative analyses. This report provides hard-to-find data on the current and future values of clinical trial spending and the CRO market, worldwide and regionally. We address global questions, such as: what proportion of the sector will be held by contract research organisations in future years? Our report also addresses regional questions. For example, how will India's share of global spending change between 2010 and 2025? Will the Central and Eastern European sector expand more rapidly than that of China? Our new report answers questions such as those, providing the information that you need.

Clinical Trials: World Market 2010-2025 examines that sector critically, through a comprehensive review of information sources. We harness primary and secondary research.
