Adaptive & Flexible Trials

Listening, learning, adapting.

Flexibility is one of the most powerful tools in your trial design arsenal. That’s why Adaptive Trial Designs give you the opportunity to reduce risk of failure by factoring in analyses at key points so study design parameters like sample size, dosage, or patient selection can be adjusted accordingly. 

In fact, a 2018 report we commissioned called The Innovation Imperative: The Future of Drug Development by The Economist Intelligence Unit (EIU) found that adaptive trial designs boost a new therapy’s likelihood of launch by 13% on average. That percentage climbs even higher in certain therapeutic areas – up to 32% for oncology. However, although this approach is encouraging, it’s still not widely used.

By implementing Adaptive Trial Designs you have the opportunity to carefully evaluate clinical data in real-time, so you can make informed decisions to change the direction of the study for a better chance of success. A well-designed and executed Adaptive Trial Design can:

  • increase the probability of success for your new therapy
  • maximize the information from the trial
  • shorten development timelines
  • reduce overall development costs and
  • reduce the risk for study volunteers and sponsors
  • maximize the probability of success with regulators and payers
