Adaptive Clinical Trials
Lead Research Organisation:
University of Cambridge
Department Name: UNLISTED
Abstract
Classically designing a clinical trial involves making assumptions about various attributes, such as the treatment effect, before any data are collected. The aim of our programme is to introduce novel designs that are more flexible. The rigidity of the classic design can lead to failed studies due to wrong assumptions such as using an optimistic treatment effect to limit the size of the study. Our novel designs will allow the use of accrued information in many ways; this includes stopping the study early for futility or efficacy, re-assessing the size of the study and recruiting more patients if need be altering dose choices during the study and identifying subgroups of patients who respond the best to treatment. Our overall goal is to minimise the number of people needed within a study whilst maintaining the statistical rigour needed to correctly answer the scientific questions.
Technical Summary
Clinical trials are considered the gold-standard study design when testing for a causal effect of a new treatment or intervention. There are, however, many challenges to be faced in the future. The high, and increasing, cost of clinical trials has caused the drug development process to become more and more expensive (DiMasi, Grabowski, and Hansen 2016), meaning new design and analysis methods to increase efficiency are greatly needed. The barriers to using adaptive clinical trials are lifting, which is leading to an increasing uptake (Hatfield et al. 2016). Members of my team are working on several current and future trials that are implementing novel methods. This portfolio of trials forms a strong basis for our future methodology research plans. I have the capacity, skills and track-record to push the methodology forward to tackle even more ambitious problems. These include dealing with patient heterogeneity, exploiting multivariate outcomes in dose-finding/ranging trials, using historical data, applying bandit methodology to improve patient benefit in trials, and conducting trials within large cohorts.
I have been successful in building links with industry with several ongoing collaborations and two postdoctoral positions jointly funded by GlaxoSmithKline (GSK) and AstraZeneca (AZ).
My proposed future work includes five main objectives:
1. proposing novel trial design and analysis approaches for patient stratification to predict treatment benefit;
2. developing multi-arm multi-stage methodology that can be applied to a broader range of trial designs and types of endpoint;
3. extending and further enhancing model-free and model-robust methodology for dose- finding and ranging trial designs;
4. improving the efficiency of trials within small populations;
5. using the richness of complex outcomes to give more informative inference.

An eminent medical statistician visits for a week and works with members of the unit. The highlight is the Armitage Lecture, where more than 100 delegates attend. This event raises the unit research profile and creates new collaborations. |

The aim of the open day was to welcome secondary school students and members of the general public to come to the unit, find out about the research the unit does, and to take part in activities that illustrate BSU research, with the overall theme being 'Fun with statistics'. An open day of this format was a first for the unit and overall it was a very successful event. There were 40 attendees over a 4 hour event. All attendees pre-booked and were split into 4 groups for a 1 hour session comprising of an introduction, participation in hands-on activities, and a brief careers talk. The small groups and length of session allowed for quality engagement between the scientists and the audience. Feedback from the attendees was very positive, and the wider MRC Festival activities that took place in Cambridge demonstrated the benefits in delivering these types of events. |

The festival also aims to raise aspirations by encouraging young people to consider a career in science, technology, engineering or mathematics. BSU take part over two full days - 'Science Saturday' and the 'Cambridge Biomedical Campus' day. The unit presents a stand with 4 - 5 interactive activities that each communicate a basic statistical method or idea, representing one of the four research themes in the unit. Each year a new activity is developed and delivered requiring scientific input from staff and students across the unit. Over the two days, BSU engage with approximately 500 adults and children who visit the festival. |
