Advancing Discoveries: Adaptive Designs in Clinical Trials

What is Adaptive?

In the past several decades there has been a recognized trend of increased spending within pharmaceutical, biopharmaceutical, medical device as well as biotechnology research without a proportional increase in success rate of clinical trials - there used to be 8 IDAs for 1 commercial success; now 16 INDs for 1 commercial success. Some of these could be due to diminishing improvement margins for new drugs, unchanging failure rates, escalating costs, and other clinical limitations. By advancing discoveries, Advanced Clinical seeks to determine the most efficient and effective way to conduct clinical trials without decreasing the safety or efficacy of the trial. Adaptive designs have recently become the frontrunner in advancing clinical trials. Adaptive designs are clinical study designs that utilize accumulating clinical data to modify the study as it progresses, without undermining the validity and integrity of the trial. Not all clinical trials are suited for adaptive design. Stay tuned for our next blog post on Adaptive Risk Management, and FDA accepted adaptive designs/regulatory perspectives!

Why do it?

Adaptive clinical designs save resources and increases efficiency of the clinical trial. Greater flexibility within the adaptive design framework can translate into better treatment of patients within trials (stopping ineffective/dangerous doses early), more efficient drug development, and better use of available resources (need for less patients). Adaptive designs are not only advantageous to drug development, but they are ethically beneficial to the patients. Trials can be cut earlier if they are ineffective, thus efficiently and effectively ensuring patients are well served with the appropriate dosages. This is most important not only because the clinical trial can save resources by cutting off ineffective arms, but the trial can also stop harmful treatments early on in order to prevent patient harm and preserve the overall safety of the clinical trial. Adaptive designs for clinical trials provide efficient tools to demonstrate the safety and effectiveness of new medical products in faster timeframes with more certainty, at lower costs, and with better information.

With adaptive study design, there are many design options that affect different aspects of a trial. above are some of the more widely known adaptive options.

Adaptive designs, though having a lot of advantages, can have some disadvantages as well. Stay tuned for our next blog posting about the risks and regulatory perspectives surrounding adaptive designs.
