An Introduction to BLRM

Posted by Cytel

Aug 31, 2016 1:11:57 PM

Traditional rule-based approaches to dose escalation such as 3+3 are widely used in early clinical development. They can be appealing due to the simplicity of execution. However, estimates produced may be highly variable and the targeting of true Maximum Tolerated Dose may be poor.  Bayesian dose escalation approaches in early phase trials can offer an effective alternative to determining the...

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...

Adaptive Designs for Evidence Based Oncology: Insights from the Experts

Posted by Esha Senchaudhuri

Sep 4, 2014 1:10:00 PM

Imagine if we were to count the number of possible reasons that investigators might have for monitoring a biomarker during a clinical trial, and multiply that number by the number of possible adaptive designs available for such investigation. We would naturally assume that whatever the number, it would be rather large. This poses an interesting question for a sponsor of an adaptive clinical...

Bayesian Trial Designs are Safe, Efficient & Flexible: A Review of Published Phase 1 Studies

Posted by Charles Liu

Aug 21, 2014 10:03:33 AM

 

 

Use of the continual reassessment method (CRM) is safe, efficient, and flexible, according to a comprehensive review of 53 published Phase I trials from 2003-2013. The review, just published in the Journal of Clinical Oncology by leading researchers Iasonas and O'Quigley, challenges common misconceptions about model-based dose escalation designs.

Photos leaked from JSM 2014 appear to show the Reverend Bayes partying with his entourage at the Cytel Cocktail Hour, held at Boston’s Seaport Hotel on August 4, 2014. Bayes is, of course, one of the stars of Cytel’s East 6.3, a modular software package driving drug development through high quality trial design and simulations. Bayes's contributions to the East ESCALATE and East PREDICT...

5 Reasons to Invest in Bayesian Dose-Escalation Methods

Posted by Esha Senchaudhuri

May 8, 2014 7:54:00 AM

( Editor's note: This post has been refreshed in December 2016)

Model based algorithms for Phase I dose-escalation have been in existence for nearly thirty years. Despite guarantees of increased statistical power and greater accuracy, there remains a clear preference for rule based algorithms amongst clinicians. The explanation for this is as old as the models themselves.
