Case Study: Improving Go/No-go Decision-Making with Custom Software

Posted by Cytel

Mar 24, 2017 9:27:00 AM

 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.

Pattern Recognition and 'Big Data'

Posted by Cytel

May 19, 2016 6:00:00 AM

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...

What's the Value of P?

Mar 23, 2016 9:30:00 AM

“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...

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.

As...

How Bayesian Strategies Can Expedite a Pediatric Clincial Trial Time by 20 - 40%

Posted by Esha Senchaudhuri

Mar 20, 2015 4:29:00 PM

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...

Drug Supply Planning for Dose-Ranging Adaptive Trials

Posted by Esha Senchaudhuri

Dec 9, 2014 12:17:28 PM

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...

A Bayesian Industry Approach to Phase I Combination Trials in Oncology

Posted by Esha Senchaudhuri

Nov 18, 2014 4:32:00 PM

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...
