Adaptive Designs: A Data Management Perspective

Posted by Cytel

Oct 7, 2016 8:29:00 AM

Adaptive designs have the potential to accelerate clinical development, and improve the probability of trial success. While the principle is simple- to reduce the uncertainty in clinical development by obtaining additional information from the ongoing trial- the statistical methodologies can be complex, and expert support is often required to conduct the clinical trial design. There's also...

Oftentimes people perceive a tradeoff between speed and quality. The faster you do something the more likely you are to make mistakes. Then again, checking everything carefully means things take a longer time.

Right?  

What if you could promise a team that could work 24-7?

Modern Early Phase Clinical Trial Design Primer

Posted by Cytel

Sep 1, 2015 4:01:39 PM

If you’re in the practice of conducting early phase clinical trials, you’ve probably heard that modern trial designs include a number of new methodologies. There’s CRM and BLRM, model-based methods versus rule-based methods, and a number of other developments that might affect your clinical strategy. Each of these methods affects operational, financial and regulatory objectives in unique ways.

Aligning Clinical Development & Regulatory Objectives for Cardiovascular Outcome Trials

Posted by Esha Senchaudhuri

Jun 11, 2015 5:21:09 PM

When the FDA first began to require pharmaceuticals to perform cardiovascular outcome trials to establish the safety of certain new drugs, many worried that this new regulatory requirement would diminish investments in therapeutic areas like diabetes and obesity [1]. CVOTs are typically designed as massive time-to-event trials that need to enroll several thousands of patients to establish safety...

How to Use Outsourcing to Reduce Clinical Development Risk

Posted by Esha Senchaudhuri

May 28, 2015 4:47:00 PM

Risks in drug development range from taking the wrong drugs forward to Phase 3 to investing in a drug development program at a time when regulatory standards are evolving, or competition is catching up with comparable products.

There is a particular source of risk, however, which deserves special attention. Currently, the pharmaceutical and biologics industry outsources approximately $25...

Last week the Cytel Blog discussed the benefits of using the Adaptive Maximizing Design [AM Design] for dose-finding trials involving clinical utility limiting therapies. However, there are other ways that a dose-finding trial can make use of frequent-adaptation maximizing designs. Here we look at what happens to early phase clinical development when an AM Design combines with another adaptive...

Adaptive SSR for Small Sample Sizes?

Posted by Esha Senchaudhuri

Apr 21, 2015 6:09:28 PM

“We shouldn’t use an adaptive design, our sample size is too small.”

Most clinical trial planners have heard this line of reasoning so often it has come to be taken as true. Never mind the fact that the first product to receive FDA approval using an adaptive sample size re-estimation design, was for a genetic condition affecting fewer than two thousand children worldwide [1].

Last year. Nature Reviews Drug Discovery asked the FDA’s Tatiana Prowell (Hematology & Oncology Products Division) about the most common pitfalls confronting clinical trials in oncology. She cited the late stage evaluations of biomarkers as one of three critical issues leading to regulatory failure [1]. The primary lesson: those who want to test biomarkers need to start earlier.

Monte Carlo Simulations II: Reassessing Strategic Options During an Interim Look

Midway through a trial is a terrible time to realize that you need a new strategy to complete the study. Sadly, it is typically midway through a trial when drug supply, patient recruitment and budget all tend to deviate from the planned development path. Sometimes this is because the initial plan utilized idealized assumptions, (i.e. non-random patient enrollment), which failed to give the...

Leveraging the Flexibility of an Adaptive Clinical Trials: A Case Study

Posted by Esha Senchaudhuri

Mar 27, 2015 5:43:52 PM

We have often said that one of the greatest benefits of an adaptive clinical trial is the flexibility it affords for decision-making [1]. Often this flexibility is taken to mean that sponsors have some leeway to accommodate events - foreseen or unforeseen, challenging or advantageous - midway through a trial. However, when designing a trial, it is often possible to leverage this flexibility...
