FDA 22 Case Studies and Mitigating Phase 3 Risks

Posted by Cytel

Apr 11, 2017 10:29:00 AM

In a January 2017 paper (1), the FDA reviewed 22 case studies where promising Phase 2 trials did not result in efficacy, safety or both being confirmed in a Phase 3 trial.

At the outset, the authors of the paper are careful to state that the aim is not to assess why these unexpected results occurred, but rather to demonstrate how different trials contribute to developing our scientific understanding of the product.

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 complexity in the data collection itself, so knowledgable data management support is needed to successfully execute an innovative trial design.  In this blog, we take a look at 5 top considerations for successful adaptive trial data management.

Adaptive Design in the limelight with NEJM article

Posted by Cytel

Jul 18, 2016 8:00:00 AM

In order for adaptive designs to reach their potential, it’s critical that knowledge is effectively dissemirnated within the medical research community – in particular detailed information about the operating and statistical characteristics of specific designs and insights as to their benefits and limitations. 

Cytel recently announced the publication of an important article in the New England Journal of Medicine which takes a leap forward in promoting better understanding of adaptive designs particularly in a confirmatory setting.  We'll discuss some of the highlights of the article in this blog.

Dual Agent Dose Escalation Designs

Posted by Cytel

Apr 22, 2016 9:30:00 AM

FDA draft guidance on “Co development of two or more unmarketed investigational drugs for use in combination”  notes that:

“Combination therapy is an important treatment modality in many disease settings, including cancer, cardio-vascular disease, and infectious diseases. Recent scientific advances have increased our understanding of the pathophysiological processes that underlie these and other complex diseases. This increased understanding has provided further impetus for new therapeutic approaches using combinations of drugs directed at multiple therapeutic targets to improve treatment response or minimize development of resistance.” In this setting, it’s important to be able to design dose escalation studies which can identify the synergistic activity of compounds, and less toxic combinations.

Adaptive SSR: Debunking the inefficiency myth

Posted by Cytel

Mar 3, 2016 3:00:00 PM

 'The aim of a discussion should not be victory but progress.'

This principle, expressed by the French essayist Joseph Joubert, applies effectively to the spirit of scientific debate. More specifically, within the clinical development space, the field of adaptive designs has seen its fair share of both discussion and progress. In this blog we’ll take a look at one debated area- the efficiency of Adaptive SSR designs.

It’s Time to Bridge the Gap Between Pharmacometrics and Biostats

Posted by Esha Senchaudhuri

Oct 1, 2015 5:22:00 PM

This week marks the sixth annual American Conference on Pharmacometrics, held this year in Crystal City, VA. Situated at the intersection of mathematical modeling, simulation and big data, the field of pharmacometrics is delivering on its promise to revolutionize clinical research and by extension clinical development.

No wonder then that biostatisticians are now fully engaged with the enterprise.

Inference on Confidence Intervals for Adaptive Designs: The Latest Breed of Adaptive Clinical Trials

Sep 17, 2015 3:51:00 PM

Most people familiar with adaptive clinical trial designs are familiar with those statistical designs that reject the null hypothesis. These include now familiar designs like the promising zone design and the adaptive switch design

A newer breed of adaptive designs, however, aims to apply adaptation techniques to confidence intervals.

Special Update: US House of Representatives Passes 21st Century Cures Act

Posted by Cytel

Jul 10, 2015 12:54:00 PM

Here at Cytel, we are engaging in a small celebration this afternoon, as the US House of Representatives has just passed the FDA Reform Bill more generally known as the 21st Century Cures Act.

Although this bill is widely viewed as a reform bill, it will provide extensive funding to both the FDA and NIH to ensure that clinical and pharmaceutical research lives up to its potential to deliver life-saving technologies in a faster, smarter way.

Title II of the act contains approximately 150 pages on drug development. We're sure some of you have read it through and through. However, for those putting off their summer reading until August, here are 4 exciting developments that we want all of our friends and affiliates to be aware:

Aligning Clinical Development & Regulatory Objectives for Cardiovascular Outcome Trials

Posted by Esha Senchaudhuri

Jun 11, 2015 5:21:09 PM

DIA_DC_Cyrus

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 [2][3]. The sheer number of patients and size of the trial increases the time that it takes for these drugs to get to market.

So what is it the makes US and EU regulatory strategy different for diabetes and weightloss drugs, and how should this effect clinical development strategy?

Seamless Adaptive Clinical Trials: Now that we get the statistics, what’s really at stake?

Posted by Esha Senchaudhuri

May 20, 2015 5:56:47 PM

Seamless adaptive clinical trials have gained popularity for reducing the projected time it takes to complete the process of drug development.  However, a study by Cuffe et al., shows that despite a tremendous amount of statistical knowledge about seamless trials, sponsors remain unsure about how to calculate the financial and operational costs of a seamless clinical development program [1]. This in turn results in many unnecessary risks and missed opportunities. This post offers advice on what you need to keep in mind in order to implement a successful seamless adaptive clinical study.

New Articles on Adaptive Clinical Trials & Adaptive Financing

Posted by Esha Senchaudhuri

Apr 30, 2015 5:00:00 PM

Adaptive financing (not to be confused with adaptive licensing) explores how biotechs, pharmaceuticals and potential investors, can use adaptive designs for more strategic financial decision-making, as well as for efficient drug development.  

“For example,” writes Zoran Antonijevic, Senior Director at Cytel Consulting, “Reduction in costs and development time can be accomplished by combining stages of development, or by early stopping for efficacy or futility. Investment risks at late stage of development can be reduced by incorporating a sample size reassessment at an interim analysis, or simply by incorporating stopping rules for efficacy and/or futility."

Zoran has just edited a volume of Clinical Investigation featuring articles on the financial and developmental benefits of adaptive clinical trial design. The volume contains a broad spectrum of issues beginning with a couple of articles on adaptive financing by Tessella’s Tom Parke, and Christopher Weir of the Health Services Research Unit at the University of Edinburgh. 

The volume also stresses the pivotal nature of dose-finding for efficient development, with contributions on Phase 2 oncology trials from Anastasia Ivanova, Guochen Song, Olga Marchenko and Stergios Moschos; as well as Meinhard Kieser, Stefan Englert and Geraldine Rauch. Thomas Jaki also explains the use of multi-arm trials in treatment selection with a look at an Alzheimer’s case.
