From early-stage studies to global, late-stage trials, oncology research is expanding at a rapid rate, and this advancing innovation has resulted in increasingly complex clinical trial protocols. Managing patient enrolment, randomisation, dosing and clinical supplies, not to mention tackling low patient recruitment levels, inefficient trial design and economic constraints, are just some of the challenges facing researchers. Brian Dunton of CRF explains how simplicity is the key to creating IRTs that enable efficient clinical trials.
