Market Dynamics

Drivers

Adoption of New Technology in Clinical Research

Digitization in biomedical research is also paving the way for market growth within the clinical trials market. Digitization also helps in meeting stringent regulations by maintaining patient data records that reduce trial process errors through the adoption of software such as electronic clinical outcome assessment (e-COA). This shift toward digital clinical trial technology helps streamline the clinical trial process, prompting sponsors to invest more in the clinical trial process, as chances of successful clinical trials increase through the adoption of newer technologies.

Shift Toward Personalized Medicine

The paradigm shift towards personalized medicine clinical trials is expected to have a positive impact on the clinical trial market. The classic clinical trial process is carried out on thousands of people, while personalized medicine focuses only on the effect of drugs on individual patients over a specific period. Very few medicines in the development phase pass all phases of a clinical trial due to the traditional clinical trial approach. The mentality of "one size fits all" acts as a barrier for drugs currently in the pipeline that would otherwise never see the day. The growing use of pharmacogenetics in clinical trials is expected to increase the number of drugs passing all phases of the clinical trial process. This shift towards personalized medicine is expected to increase the use of pharmacogenetics in the clinical trial phase, thereby increasing the drug pipeline. This trend is expected to instigate biopharmaceutical companies to invest more in the clinical trial phase.

Growing Disease Variation and Prevalence

Growing prevalence of disease and incidence of new disease is expected to give a further boost to the clinical trial market. The worldwide population has a varied disease profile, with emerging countries having the most diverse disease profile. This is expected to boost the rare disease clinical trials market for new or rare conditions that would otherwise not have found sponsors. A greater number of patients having a specific disease would act as a stimulus for biopharmaceutical companies to invest more in clinical trials for that disease segment. A diverse population would also mean easier patient recruitment and a faster clinical trial process. Rare diseases are given "Orphan disease" status in the U.S., and biopharmaceutical companies that sponsor orphan drug clinical trials receive incentives for the process. This trend is likely to have a positive impact on clinical trials for rare diseases, thereby increasing the global clinical trials market.

Increasing Collaboration in Biomedical Research

The trend of combination trials and collaborations in clinical trials is expected to rise, which would further boost the global clinical trials market. Due to high drug development costs, biopharmaceutical companies are increasingly forming alliances with each other to pool resources and share the risk of high costs. Immuno-oncology collaborations in 2015 are a prime example of increased collaboration to manage the risk associated with clinical trials. A recent example of an immuno-oncology collaboration is that of MSD and Lilly for the clinical trial phase for the treatment of advanced soft tissue sarcoma.

The race to launch molecules in the market within a feasible timeline and cost will propel demand within the clinical trials market. Pharmaceutical companies, along with increased research costs, also face growing global regulatory complexity. All these variables create a need for expertise across different portfolios, driving demand for pharma CRO partnerships. Drug companies are not only outsourcing the production of medicines but also clinical trials themselves. With increasing clinical trial privatization, there is a surge in outsourcing to developing countries such as India, China, and Latin America.
