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.

Setting the Right Foundations: The Role of the Independent Randomization Center

Posted by Liz Cole

Mar 20, 2017 9:54:00 AM

 In the randomized clinical trial (RCT), the process of deciding the randomization method and implementing is critically important. Unfortunately, it is not unheard of for problems to arise. In an article (Downs et al 2010 1), it is noted that as well as initial errors of trial design, problems can arise from errors with programming of the randomization or even human error during the course of...

The Data Management Plan Takes Center Stage- why is it so important?

Posted by Cytel

Mar 15, 2017 8:51:00 AM

 

A precise and thorough approach to planning is key for success in data management.

The Data Management Plan (DMP) is a critical document in any data management project. It outlines all of the data management work to be done, the timelines and milestones to be achieved, as well as the outputs to be produced. The DMP lets all of the stakeholders know what to expect, how to expect it and when...

Accelerating development with combined SAD/MAD approach

Posted by Cytel

Jan 30, 2017 9:50:24 AM

Single ascending dose (SAD) and multiple ascending dose (MAD) studies are typically the first in human studies.  They seek to gain information on safety and tolerability, general pharmacokinetic (PK) and pharmacodynamic ( PD)  characteristics, and of course identify the maximum tolerated dose (MTD).

Conventionally, SAD  and MAD studies were conducted separately, but increasingly are combined...
