A recent paper The case for Bayesian methods in benefit-risk assessment: Overview and future directions (1) co-authored by Cytel Senior Vice President Consulting Yannis Jemiai and published in Therapeutic Innovation and Regulatory Science, tackles the critical issue of benefit risk assessment, and the part Bayesian approaches can play in resolving their challenges.
There is certainly an...

Robust go/no-go (GNG) decision-making is essential for effectively managing risk across a clinical portfolio. In early phase development, it is particularly important to have the correct tools in place to terminate ineffective compounds quickly, while accelerating promising ones through the process.

We continue our case study series with this example of a Phase 3 design that uses Bayesian decision making combined with frequentist final analysis.
Clinical Development Background
Our biopharmaceutical client’s lead drug candidate is a late clinical-stage cancer immunotherapy for treatment of a rare oncology indication. Clinical development of therapies in this indication faces inherent...

Last week, we were delighted to announce the release of East 6.4 bringing further cutting –edge approaches to the East user community. East is the industry standard platform for clinical trial design, simulation, and monitoring, improving scientific productivity during the critical planning stages of clinical development. In this blog we catch up with Yannis Jemiai, VP of Cytel to gain some...

The explosion in healthcare information and “big data “has been one of the most written about topics in the last few years. These big data in the form of electronic health records, diagnostic tests, genomics, proteomics, not to mention data from wearable devices and apps have the potential to transform healthcare. That potential can only be realized though through the application of advanced...

On March 16th and 17th the 5th East User Group Meeting took place in London. This very successful 2 days saw a variety of talks on aspects of clinical trial design innovation. Over the next couple of weeks, we will be reviewing some of the key topics which were addressed during the meeting.
In this post, we'll take a look at Paul Frewer of Astrazeneca's presentation on Decision Making in...

“How many statisticians does it take to ensure at least a 50% chance of a disagreement about p-values?”
So questions George Cobb of Mt. Holyoke College in his commentary on the ASA’s 7th March ‘Statement on P Values: context, process and purpose’
The association took the unprecedented step of publishing the statement following a long litany of criticism of misuse of the P value. This included...

Last week Cytel joined forces with Sanofi/Genzyme to devote a full day of workshops and talks related to modern methods in early phase oncology. Patrick Mitchell, an Associate Director of Statistical Sciences at Astra Zeneca, gave this talk on Bayesian go/no-go decision-making in an early phase oncology event study.
Astra Zeneca recently invited Cytel to take part in a collaborative initiative...

Here at Cytel we have enjoyed following the debates on the p-value controversy currently taking place on the ASA website, and indeed debating the issue ourselves. While we plan to post our views on the topic in the weeks to come, we would like to invite your thoughts on the issue as well.

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.
As...

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...

Sometimes a new candidate drug for a pediatric study has already been tested on adults for safety and efficacy. We know that the drug is likely to work quite differently in children, but we do not know the degree to which the effects will be different. As a result, a conventional approach is to discard much of the information that has already gathered during studies of adults, and then to start...

21st Century Cures (also called Cures2015) is a bipartisan initiative undertaken by the Committee on Energy and Commerce of the US House of Representatives. Amongst the many factors motivating this landmark legislation is the concern that regulatory procedures must keep up to date with innovations in clinical development. Cures2015 aims to reform the regulation of drugs, biologics and medical...

February 2015 marks the five year anniversary of the FDA’s Guidance on Adaptive Design Clinical Trials for Drug and Biologics, as well as the FDA’s Guidance on the Use of Bayesian Statistics in Medical Device Clinical Trials. In honor of the five year anniversary of both sets of guidance, the DIA will hold a special joint conference between its Adaptive Design working group and its working group...

When planning a conventional trial, one can anticipate the drug supply necessary for the trial by determining how the number of patients reflected in the sample size will distribute across the trial sites. Implementing an adaptive trial, by contrast, raises many challenges for predicting the necessary drug supply. It can require planning for different sample sizes depending on the outcome of...

Statisticians and scientists at Novartis have been at the forefront of developing a new method in early phase oncology trials called the BLRM. Many believe that the BLRM, (short for the Bayesian Logistic Regression Method,) allows for the construction of clinical trials that have the dual benefit of improving treatment for patients participating in the trials, and allowing the trial to complete...
