Randomised trials are the best way to find out what treatments work, but they can be slow and expensive. We are inventing new and efficient ways to design randomised trials that can give clear answers, often answering multiple questions within the same trial. This work is supported by detailed statistical modelling to show how to analyse the new designs while strictly controlling the risk of wrongly concluding that a treatment is effective when in truth it isn’t. The new designs are implemented in our own trials, and this helps us to refine the designs and demonstrate their value for other trials.Our novel designs are for 1. trials to evaluate whether it is safe to shorten the duration of treatment or use a treatment with fewer side effects;2. trials to evaluate multiple treatments, where we can drop treatments that are found to be ineffective, adopt the use of treatments that are found to be effective, and start evaluating new promising treatments;3. trials that work even when the benefit of treatment is short-term or delayed; 4. trials where groups of patients are randomised rather than individual patients; 5. trials specifically designed to evaluate treatments tailored to specific types of patient; and6. trials comparing a number of treatments, where some patients cannot receive some of the treatments.The results of our work are that treatments can be evaluated faster, more effectively and more cost-effectively.

随机试验是找出哪种治疗方法有效的最佳方法，但它们可能缓慢且昂贵。我们正在发明新的有效方法来设计随机试验，这些试验可以给出明确的答案，通常在同一试验中回答多个问题。这项工作得到了详细的统计模型的支持，该模型展示了如何在分析新设计的同时严格控制错误地得出治疗有效的结论的风险，而实际上治疗无效。新设计在我们自己的试验中实施，这有助于我们改进设计并展示其对其他试验的价值。我们的新颖设计是给1个人的。2.评估缩短治疗时间或使用副作用较少的治疗方法是否安全的试验；2 .评估多种治疗方法的试验，我们可以放弃发现无效的治疗方法，采用发现有效的治疗方法，并开始评估新的有希望的治疗方法；即使治疗的益处是短期的或延迟的，试验也能起作用；4. 随机分组患者而非单个患者的试验；5. 专为评估针对特定类型患者的治疗方法而设计的试验；and6。试验比较了一些治疗方法，其中一些患者不能接受某些治疗。我们工作的结果是可以更快、更有效、更经济地评估治疗。
