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 trial. Maintaining the rigor of the RCT relies on robust and reliable randomization with no errors. If treatment allocation is inadequately concealed then overestimation of treatment effect can occur, and the ‘randomized’ control trial becomes effectively ‘non-randomized’ – putting the entire study at risk (2).

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 to expect it.

The Society for Clinical Data Management (SCDM)‘s publication, Good Clinical Data Management Practices (GCDMP) (1), provides a complete chapter on Data Management Plans. (The GCDMP is available, even to non-members of the society, at their webpage).   It is important to note that while DMPs are not regulated documents, they are in fact so commonly used across the industry they have become auditable, and therefore scrupulously close attention needs to paid to getting them right.

We outline 4 key points to bear in mind when creating or reviewing a Data Management plan.

Use a Standard Template for Consistency 

To a great extent, the DMP can, and should be standardized across projects for a consistent approach. When using a centralized biometrics model, where data services( data management, statistics, statistical programming) are conducted by a single provider, the development of such standard documents can represent an efficiency in the study set up, and also reduce the oversight burden for the sponsor.  Indeed, for any trial project, a robust Data Management Plan template provides a solid starting point.   One of the important challenges facing industry professionals today is the increasing complexity of clinical trials, and as such, great care needs to be taken to ensure the DMP accurately documents what actions will be taken with the trial data.  Having a highly experienced data management team working on your project, with a track record of implementing innovative and complex trial designs, therefore, becomes increasingly important in this environment.

The Making of a CDISC Trainer

Posted by Cytel

Feb 6, 2017 9:10:00 AM

 

CDISC is a global, nonprofit charitable organization whose mission is ‘to inform patient care and safety through higher quality medical research’.  The organization delivers this mission through the development of data standards designed to streamline clinical research- these standard formats are increasingly expected for use in data submissions by regulatory authorities. Importantly, data standardization also brings significant benefits to the industry- in the CDISC 2014 Business Case (1),  it is noted that:

 “For those developing regulatory eSubmissions, using updated baseline numbers for the time and cost of getting a drug to market, it can be found that ~ $180M can be saved per submission (18% of the total cost). An average of two years can be saved off of an average 12-year clinical development program lifecycle – just by standardizing data”.

It’s therefore critical that the biopharma and CRO industries develop the next generation of data managers, statisticians and programmers with strong knowledge of the CDISC standards.


Angelo Tinazzi has more than 20 years’ experience in data-management and statistical programming and is Director of Clinical Data Standards and Data Submission at Cytel.  He has been a member of the European CDISC Committee since 2015 and is a member of the CDISC ADaM team. Taking the next step in his journey as a data standards expert, Angelo is now a "candidate trainer" with CDISC –working towards becoming an “Authorized CDISC Instructor”.  In this blog we find out more from Angelo about his experiences and the role of the CDISC trainer.

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 into an ‘umbrella’ protocol which addresses both SAD and MAD objectives.

CDISC submissions- are you up to speed?

Posted by Cytel

Dec 21, 2016 9:45:00 AM

 

December 18th 2016 was a significant date for the pharmaceutical industry and regulatory submissions. For trials which commence after this date, the FDA will no longer accept non-CDISC data submissions for new drug applications ( NDAs) , certain investigational new drug applications, abbreviated new drug applications (ANDAs)  and certain biologics license applications (BLAs).

 The FDA guidance Providing Regulatory Submissions  In Electronic Format —  Standardized Study Data (1)  also notes that the requirement will include ‘all subsequent submissions, including amendments, supplements, and reports’  to the submission types.

With regard to other regulatory agencies position on CDISC, the Japanese Pharmaceuticals and Medical Devices agency ( PMDA) will now request CDISC compliant submissions after October 2016 with a certain transitional period. This will be fully mandatory by 2018. While the European Medicines Agency (EMA)  is adopting a top-down approach and therefore more focused on topics such as data transparency, issues of data integration and interoperability will also form part of the EMA’s future plans.  

With this in mind, any sponsor planning an NDA, BLA or other regulatory submission needs to make sure they are observing best practice with regards to CDISC.  In this blog, we outline some of the key issues to bear in mind as you prepare for your data submission.

How do CDASH standards build data quality?

Posted by Cytel

Dec 20, 2016 9:21:00 AM

 

Data Standards play a crucial role in structuring and promoting long term value of clinical data.

Clinical Data Acquisitions Standards Harmonization or CDASH was developed with participation from all three ICH regions (US, Europe and Japan) with recommended data collection fields for 16 domains-> DEMOG, AE etc. It also includes  implementation guidelines, best practice recommendations, and regulatory references.  There is sometimes a misconception that CDASH defines the layout of the CRF and eCRF.  This is not the case.  The function of CDASH is to define the naming conventions for the clinical database, and outline how variables are mapped to SDTM. It defines how questions should be formulated for data collection within the CRF and eCRF making use of standard CDISC controlled terminology. In this blog, we will provide an example of CDASH implementation.
